The policemans mysterious shooting, while he was with the woman on a moonlit dock late at night, shows even those living the life of luxury can lose it all in an instant. Im not surprised at this bizarre turn of events at all.

The strange circumstances surrounding the fatal late-night shooting of a police superintendent, allegedly by the daughter-in-law of a UK billionaire with whom he was watching the moon, have caught the imagination of people across the world, but on this beautiful tropical island, the bizarre and the brutal are never too far away.

As a former long-time resident of Ambergris Caye, a sun-soaked stretch of sand, mangroves and coconut palms in the Caribbean Sea 16 miles (25 kilometers) off the mainland of Belize, Central America, nothing that happens there would surprise me.

So, when I heard of Canadian businesswoman Jasmine Hartins arrest over the death of police superintendent Henry Jemmott, it was not a case of but that sorta thing never happens there. And even once the facts began to emerge that the 38-year-old was the partner of megabucks Tory party donor Lord Ashcrofts youngest son, Andrew, that she and the superintendent, 42, were enjoying the moonlight alone together on a dock at 1am after an evening of drinking together, that she was giving him a shoulder rub and accidentally shot him in the head with his own gun, that the dead man fell on her and so she pushed his body into the water it was still not that surprising.

After all, this is the place where, once, on a visit to a police station, I couldnt help but admire the flourishing marijuana plant on a windowsill. Where a local family used to buy chickens from the supermarket to feed a 15-foot-long (4.5-meter-long) crocodile that visited their front yard each evening watched by spectators, like me, sitting in golf carts. They might have lost two dogs to the insatiable beast, but no one messed with the kids at school. Unusual things elsewhere are commonplace on Ambergris Caye.

The incident marks the first murder of the year in San Pedro, the islands only town, which, since Covid-19 struck and lockdown was imposed, has seen a drop in crime, recording just one murder last year: the slaying of Marisela Gonzales, for which her husband, David, was later charged.

There were still plenty of other crimes, however, and even a bizarre case in which disciplinary action was meted out to a female San Pedro police officer who was caught on CCTV helping herself to a prisoners belongings.

There were two separate armed robberies in just one day in September; in November, there was the spectacular bonfire of more than 220 pounds (100 kilograms) of seized drugs, including marijuana, cocaine and ecstasy tablets; a former San Pedro policeman was charged with rape of a minor; three fishermen were remanded in custody for an attempted kidnapping, burglary and wounding; and all this on top of the usual seizures of cash proceeds from drug-dealing, the items taken illegally from the offshore marine reserve, and the deportation of border-jumpers and US felons who regularly turn up in town looking to lay low.

Nevertheless, 2020 was quiet, particularly when compared with the year before, which saw a total of 12 murders on an island of just 15,000 citizens which was part of a 30% reduction in crime compared to 2018.

While the tourist brochures paint an alluring picture of No shoes? No shirt? No problem!, San Pedro is actually a hustling, traffic-choked Central American town. As on many Caribbean islands, once you stray from the bars, restaurants and colourful shops of the beachfront, what my Belizean friends call Second World poverty stares you straight in the face. Its an unsettling and stark contrast to the carefree, cocktail-enhanced, hammock-swinging hedonism the tourists enjoy.

Ambergris Caye is a well-known drop-off point for the drug cartels of South America on the way to Mexico and further north, and plenty of funny money and drugs washes around in the local economy, so it pays to stay alert.

Away from prying eyes, to the north of the caye, which extends around 28 miles towards the Yucatan Peninsula, criminals go about their business unmolested, trafficking drugs, smuggling contraband among the mangroves and even settling scores as the two bodies found in a shallow grave a few years ago would suggest.

Popular American singer-songwriter Jimmy Buffett is a regular visitor to San Pedro, Hes currently building a Margaritaville resort named after his 1977 hit and aimed at enticing island dreamers from the US to invest in a condo in paradise and no doubt hell have plenty of takers.

Its the same idea that Jasmine Hartin and her partner Andrew Ashcroft had with the beachfront resort they run. But, unfortunately for them, their tropical dream has turned into a nightmare. A policeman is dead. The daughter-in-law of a rich, powerful man with extensive business interests in Belize is being held responsible, and the authorities are under intense scrutiny to ensure justice is not only done, but is seen to be done.

To holidaymakers, the Caribbean lifestyle is all about lazy days, wide smiles and sand between your toes, with a ready drink to hand. For those who live there all year round, alarming encounters with the darker side of life in the tropics are all too often unavoidable.

NASAs Mars Exploration Program

Astrobiology is a relatively new field of study, where scientists from a variety of disciplines (astronomy, biology, geology, physics, etc.) work together to understand the potential for life to exist beyond Earth. However, the exploration of Mars has been intertwined with NASAs search for life from the beginning. The twin Viking landers of 1976 were NASAs first life detection mission, and although the results from the experiments failed to detect life in the Martian regolith, and resulted in a long period with fewer Mars missions, it was not the end of the fascination that the Astrobiology science community had for the red planet.

The field of Astrobiology saw a resurgence due to the controversy surrounding the possible fossil life in the ALH84001 meteorite, and from the outsized public response to this announcement, and subsequent interest from Congress and the White House, NASAs Astrobiology Program (https://astrobiology.nasa.gov/ )and one of its major programs, the NASA Astrobiology Institute (https://nai.nasa.gov/ ) were formed.

Also at this time, NASAs Mars Exploration Program began to investigate Mars with an increasing focus on missions to the Red Planet. The Pathfinder mission and Mars Exploration Rovers (Spirit and Opportunity) were sent to Mars to Follow the Water, recognizing that liquid water is necessary for life to exist on Earth. After establishing that Mars once had significant amount of water on its surface, the Mars Science Laboratory (which includes the Curiosity rover) was sent to Mars to determine whether Mars had the right ingredients in the rocks to host life, signaling a shift to the next theme of Explore Habitability. MEP is now developing the Mars 2020 rover mission (https://mars.jpl.nasa.gov/mars2020/ ) to determine whether life may have left telltale signatures in the rocks on Marss surface, a further shift to the current science theme Seek the Signs of Life.

Finding fossils preserved from early Mars might tell us that life once flourished on this planet. We can search for evidence of cells preserved in rocks, or at a much smaller scale: compounds called biosignatures are molecular fossils, specific compounds that give some indication of the organisms that created them. However, over hundreds of millions of years these molecular fossils on Mars are subject to being destroyed or transformed to the point where they may no longer be recognized as biosignatures. Future missions must either find surface regions where erosion from wind-blown sand has recently exposed very ancient material, or alternately samples must be obtained from a shielded region beneath the surface. This latter approach is being taken by the ExoMars rover (http://exploration.esa.int/mars/48088-mission-overview/ ) under development where drilled samples taken from a depth of up to 2 meters will be analyzed.

What makes a planet a dwarf planet? How many miles are in a light-year? What exactly is a quasar? Launch into other worlds while testing your knowledge about space, celestial bodies, and the solar system.

Sometimes called the Red Planet, Mars has long been associated with warfare and slaughter. It is named for the Roman god of war. As long as 3,000 years ago, Babylonian astronomer-astrologers called the planet Nergal for their god of death and pestilence. The planets two moons, Phobos (Greek: Fear) and Deimos (Terror), were named for two of the sons of Ares and Aphrodite (the counterparts of Mars and Venus, respectively, in Greek mythology).

In recent times Mars has intrigued people for more-substantial reasons than its baleful appearance. The planet is the second closest to Earth, after Venus, and it is usually easy to observe in the night sky because its orbit lies outside Earths. It is also the only planet whose solid surface and atmospheric phenomena can be seen in telescopes from Earth. Centuries of assiduous studies by earthbound observers, extended by spacecraft observations since the 1960s, have revealed that Mars is similar to Earth in many ways. Like Earth, Mars has clouds, winds, a roughly 24-hour day, seasonal weather patterns, polar ice caps, volcanoes, canyons, and other familiar features. There are intriguing clues that billions of years ago Mars was even more Earth-like than today, with a denser, warmer atmosphere and much more waterrivers, lakes, flood channels, and perhaps oceans. By all indications Mars is now a sterile frozen desert. However, close-up images of dark streaks on the slopes of some craters during Martian spring and summer suggest that at least small amounts of water may flow seasonally on the planets surface, and radar reflections from a possible lake under the south polar cap suggest that water may still exist as a liquid in protected areas below the surface. The presence of water on Mars is considered a critical issue because life as it is presently understood cannot exist without water. If microscopic life-forms ever did originate on Mars, there remains a chance, albeit a remote one, that they may yet survive in these hidden watery niches. In 1996 a team of scientists reported what they concluded to be evidence for ancient microbial life in a piece of meteorite that had come from Mars, but most scientists have disputed their interpretation.

Since at least the end of the 19th century, Mars has been considered the most hospitable place in the solar system beyond Earth both for indigenous life and for human exploration and habitation. At that time, speculation was rife that the so-called canals of Marscomplex systems of long, straight surface lines that very few astronomers had claimed to see in telescopic observationswere the creations of intelligent beings. Seasonal changes in the planets appearance, attributed to the spread and retreat of vegetation, added further to the purported evidence for biological activity. Although the canals later proved to be illusory and the seasonal changes geologic rather than biological, scientific and public interest in the possibility of Martian life and in exploration of the planet has not faded.

During the past century Mars has taken on a special place in popular culture. It has served as inspiration for generations of fiction writers from H.G. Wells and Edgar Rice Burroughs in the heyday of the Martian canals to Ray Bradbury in the 1950s and Kim Stanley Robinson in the 90s. Mars has also been a central theme in radio, television, and film, perhaps the most notorious case being Orson Welless radio-play production of H.G. Wellss novel War of the Worlds, which convinced thousands of unwitting listeners on the evening of October 30, 1938, that beings from Mars were invading Earth. The planets mystique and many real mysteries remain a stimulus to both scientific inquiry and human imagination to this day.

Mars, the red planet: Facts and information

The red planet Mars, named for the Roman god of war, has long been an omen in the night sky. And in its own way, the planets rusty red surface tells a story of destruction. Billions of years ago, the fourth planet from the sun could have been mistaken for Earths smaller twin, with liquid water on its surfaceand maybe even life.

Now, the world is a cold, barren desert with few signs of liquid water. But after decades of study using orbiters, landers, and rovers, scientists have revealed Mars as a dynamic, windblown landscape that couldjust maybeharbor microbial life beneath its rusty surface even today.

With a radius of 2,106 miles, Mars is the seventh largest planet in our solar system and about half the diameter of Earth. Its surface gravity is 37.5 percent of Earths.

Mars 101

Recent NASA exploratory expeditions revealed some of the red planet's biggest mysteries. This video explains what makes it so different from Earth and what would happen if humans lived there.

Mars rotates on its axis every 24.6 Earth hours, defining the length of a Martian day, which is called a sol (short for solar day). Marss axis of rotation is tilted 25.2 degrees relative to the plane of the planets orbit around the sun, which helps give Mars seasons similar to those on Earth. Whichever hemisphere is tilted closer to the sun experiences spring and summer, while the hemisphere tilted away gets fall and winter. At two specific moments each yearcalled the equinoxesboth hemispheres receive equal illumination.

But for several reasons, seasons on Mars are different from those on Earth. For one, Mars is on average about 50 percent farther from the sun than Earth is, with an average orbital distance of 142 million miles. This means that it takes Mars longer to complete a single orbit, stretching out its year and the lengths of its seasons. On Mars, a year lasts 669.6 sols, or 687 Earth days, and an individual season can last up to 194 sols, or just over 199 Earth days.

The angle of Marss axis of rotation also changes much more often than Earth's, which has led to swings in the Martian climate on timescales of thousands to millions of years. In addition, Marss orbit is less circular than Earths, which means that its orbital velocity varies more over the course of a Martian year. This annual variation affects the timing of the red planets solstices and equinoxes. On Mars, the northern hemispheres spring and summer are longer than the fall and winter.

Theres another complicating factor: Mars has a far thinner atmosphere than Earth, which dramatically lessens how much heat the planet can trap near its surface. Surface temperatures on Mars can reach as high as 70 degrees Fahrenheit and as low as -225 degrees Fahrenheit, but on average, its surface is -81 degrees Fahrenheit, a full 138 degrees colder than Earths average temperature.

The primary driver of modern Martian geology is its atmosphere, which is mostly made of carbon dioxide, nitrogen, and argon. By Earth standards, the air is preposterously thin; air pressure atop Mount Everest is about 50 times higher than it is at the Martian surface. Despite the thin air, Martian breezes can gust up to 60 miles an hour, kicking up dust that fuels huge dust storms and massive fields of alien sand dunes.

Once upon a time, though, wind and water flowed across the red planet. Robotic rovers have found clear evidence that billions of years ago, lakes and rivers of liquid water coursed across the red planets surface. This means that at some point in the distant past, Marss atmosphere was sufficiently dense and retained enough heat for water to remain liquid on the red planets surface. Not so today: Though water ice abounds under the Martian surface and in its polar ice caps, there are no large bodies of liquid water on the surface there today.

Mars also lacks an active plate tectonic system, the geologic engine that drives our active Earth, and is also missing a planetary magnetic field. The absence of this protective barrier makes it easier for the suns high-energy particles to strip away the red planets atmosphere, which may help explain why Marss atmosphere is now so thin. But in the ancient pastup until about 4.12 to 4.14 billion years agoMars seems to have had an inner dynamo powering a planet-wide magnetic field. What shut down the Martian dynamo? Scientists are still trying to figure out.

Like Earth and Venus, Mars has mountains, valleys, and volcanoes, but the red planets are by far the biggest and most dramatic. Olympus Mons, the solar systems largest volcano, towers some 16 miles above the Martian surface, making it three times taller than Everest. But the base of Olympus Mons is so widesome 374 miles acrossthat the volcanos average slope is only slightly steeper than a wheelchair ramp. The peak is so massive, it curves with the surface of Mars. If you stood at the outer edge of Olympus Mons, its summit would lie beyond the horizon.

Mars has not only the highest highs, but also some of the solar systems lowest lows. Southeast of Olympus Mons lies Valles Marineris, the red planets iconic canyon system. The gorges span about 2,500 miles and cut up to 4.3 miles into the red planets surface. The network of chasms is four times deeperand five times longerthan Earths Grand Canyon, and at its widest, its a staggering 200 miles across. The valleys get their name from Mariner 9, which became the first spacecraft to orbit another planet when it arrived at Mars in 1971.

About 4.5 billion years ago, Mars coalesced from the gaseous, dusty disk that surrounded our young sun. Over time, the red planets innards differentiated into a core, a mantle, and an outer crust thats an average of 40 miles thick.

Its core is likely made of iron and nickel, like Earths, but probably contains more sulfur than ours. The best available estimates suggest that the core is about 2,120 miles across, give or take 370 milesbut we dont know the specifics. NASAs InSight lander aims to unravel the mysteries of Marss interior by tracking how seismic waves move through the red planet.

Marss northern and southern hemispheres are wildly different from one another, to a degree unlike any other planet in the solar system. The planets northern hemisphere consists mostly of low-lying plains, and the crust there can be just 19 miles thick. The highlands of the southern hemisphere, however, are studded with many extinct volcanoes, and the crust there can get up to 62 miles thick.

What happened? Its possible that patterns of internal magma flow caused the difference, but some scientists think it's the result of Mars suffering one or several major impacts. One recent model suggests Mars got its two faces because an object the size of Earths moon slammed into Mars near its south pole.

Both hemispheres do have one thing in common: Theyre covered in the planets trademark dust, which gets its many shades of orange, red, and brown from iron rust.

At some point in the distant past, the red planet gained its two small and irregularly shaped moons, Phobos and Deimos. The two lumpy worlds, discovered in 1877, are named for the sons and chariot drivers of the god Mars in Roman mythology. How the moons formed remains unsolved. One possibility is that they formed in the asteroid belt and were captured by Marss gravity. But recent models instead suggest that they could have formed from the debris flung up from Mars after a huge impact long ago.

Deimos, the smaller of the two moons, orbits Mars every 30 hours and is less than 10 miles across. Its larger sibling Phobos bears many scars, including craters and deep grooves running across its surface. Scientists have long debated what caused the grooves on Phobos. Are they tracks left behind by boulders rolling across the surface after an ancient impact, or signs that Marss gravity is pulling the moon apart?

Either way, the moons future will be considerably less groovy. Each century, Phobos gets about six feet closer to Mars; in 50 million years or so, the moon is projected either to crash into the red planets surface or break into smithereens.

Since the 1960s, humans have robotically explored Mars more than any other planet beyond Earth. Currently, eight missions from the U.S., European Union, Russia, and India are actively orbiting Mars or roving across its surface. But getting safely to the red planet is no small feat. Of the 45 Mars missions launched since 1960, 26 have had some component fail to leave Earth, fall silent en route, miss orbit around Mars, burn up in the atmosphere, crash on the surface, or die prematurely.

More missions are on the horizon, including some designed to help search for Martian life. NASA is building its Mars 2020 rover to cache promising samples of Martian rock that a future mission would return to Earth. In 2020, the European Space Agency and Roscosmos plan to launch a rover named for chemist Rosalind Franklin, whose work was crucial to deciphering the structure of DNA. The rover will drill into Martian soil to hunt for signs of past and present life. Other countries are joining the fray, making space exploration more global in the process. In July 2020, the United Arab Emirates is slated to launch its Hope orbiter, which will study the Martian atmosphere.

Perhaps humans will one day join robots on the red planet. NASA has stated its goal to send humans back to the moon as a stepping-stone to Mars. Elon Musk, founder and CEO of SpaceX, is building a massive vehicle called Starship in part to send humans to Mars. Will humans eventually build a scientific base on the Martian surface, like those that dot Antarctica? How will human activity affect the red planet or our searches for life there?

Time will tell. But no matter what, Mars will continue to occupy the human imagination, a glimmering red beacon in our skies and stories.

Mars, the red planet: Facts and information

How NASA is hunting for signs of life on Mars – PBS NewsHour

Perseverance, NASAs latest rover, landed on Mars in February with a mission to answer questions about the past and future of life on the Red Planet.

Over the course of that mission lasting nearly two years, or one Martian year the rover will conduct research using a range of instruments designed to probe the planets landscape for glimpses into its ancient past.

Researchers hope to gain a better sense of whether primordial life once existed on our celestial neighbor (and if so, where and when), and how technology may pave the way for astronauts to sustain their own lives during future voyages to its now-desolate surface.

In a few short months, the rover and its companions have achieved massive technological feats and uncovered a trove of meaningful data and fascinating photos. Perseverance has already overseen the successful demonstration of two pieces of experimental technology a small helicopter named Ingenuity and a toaster-sized contraption called MOXIE that converts Marss carbon dioxide-heavy atmosphere into oxygen.

The rover is stationed in Marss Jezero Crater, which researchers believe was home to a lake more than 3.5 billion years ago. Researchers back home have been rolling out software updates and checking out the highly autonomous vehicles accessories. Over the next few weeks, Perseverance will begin evaluating local geology in search of rock samples that may hold important clues.

Ultimately, the hope is that a future mission can pull off the complicated task of transporting a cache of those samples to Earth for further study. (That plan is still a proposal for now, and hasnt yet been signed off on by NASA.)

Its been an eventful first few months for Perseverance, its technological companions and the hundreds of researchers who monitor and operate them here on Earth. Heres a look at what they have accomplished, and whats next for the mission.

In NASAs Mars mission, MOXIE means more than spunk and determination it stands for Mars Oxygen In-Situ Resource Utilization Experiment (in-situ means in place). In April, the pint-sized piece of tech achieved its goal of extracting oxygen from the Martian atmosphere.

Pulling carbon dioxide from the atmosphere and splitting it into carbon monoxide and oxygen, the device produced about 5 grams of oxygen, roughly enough for an astronaut to breathe for 10 minutes.

During the missions first year, MOXIE will perform that demonstration up to 10 times. The density of the planets atmosphere changes dramatically depending on factors like whether its night or day which significantly influences temperature as well as which season it is. Researchers aim to determine whether it will work in those varying conditions.

The basic idea is to produce oxygen during all seasons, during all times of day, and thats the plan, said Jeffrey Hoffman, a former astronaut and current deputy principal investigator of the MOXIE experiment.

An air pump pulls in carbon dioxide gas from the Martian atmosphere, which is then regulated and fed to the Solid OXide Electrolyzer (SOXE), where it is electrochemically split to produce pure oxygen. Credit: NASA/JPL-Caltech

If future generations of MOXIE ever accompany astronauts on trips to Mars, the machine will have to be equipped to run at all times the existing MOXIE must be turned on and allowed to heat up to about 1,400 degrees Fahrenheit ahead of each demonstration and automatically calibrate itself to safely convert atmosphere at any density.

One of the purposes of MOXIE is not just to demonstrate that it works, but to learn enough about the whole system so that we can actually help inform the design of a much larger scale autonomous oxygen producing system, which is the ultimate goal of this whole enterprise, Hoffman said.

A crew of six astronauts sustaining themselves on Mars for two or so years would need maybe a ton of oxygen, he added. The rocket theyd rely on to lift them off Mars and return them home would need about 25 to 30 times as much oxygen to fire up.

Sending all of that oxygen with any given mission would be a monumental and expensive feat. If you can produce the oxygen you need on Mars instead of lugging it there, youre way ahead of the game, Hoffman said.

The Ingenuity helicopter is the first remotely controlled aircraft to successfully take flight on a planet other than our own.

This mission makes a huge difference in showing its not just a dream, said Havard Grip, who serves as Ingenuitys chief pilot and flight control lead. This is reality.

Five test flights were planned for Ingenuity, each planned to be a little bit farther or faster than the one before it. The experiment was such a resounding success that Ingenuity keeps taking to the air.

During its sixth flight, an error occurred for the first time: One of images that Ingenuity regularly takes to orient itself was lost, meaning that each subsequent image had an inaccurate timestamp. That confused the helicopters system, Grip explained. It began trying to correct things that werent really errors, which impacted the algorithm thats used to keep Ingenuity stable and under control.

Fortunately, NASA engineers designed the helicopter to account for timing errors, so Ingenuity was able to complete a safe landing.

This obstacle, an unknown unknown challenge, as researchers sometimes put it, offered a kind of stress test, which Ingenuity passed handily.

We were extremely pleased with how everything has been performing up until this point, Grip said. And really that can be said for flight six, too, in many ways.

This black-and-white image was taken by the navigation camera aboard NASAs Ingenuity helicopter during its third flight, on April 25, 2021. Credit: NASA/JPL-Caltech

Plans for flight seven involve sending the helicopter around 350 feet south of where it now sits, and will be the second time Ingenuity will land at an airfield that it did not survey from the air during a previous flight, according to NASA. Researchers are confident that this location is relatively flat and has few surface obstructions based on images captured by NASAs Mars Reconnaissance Orbiter.

Ingenuitys performance so far has generated mountains of useful data, Grip said, especially regarding how the helicopter itself has behaved in real-life conditions on Mars. Much like MOXIE, that information will be invaluable when it comes to engineering future generations of comparable technology.

Grip emphasized that theres no expectation that anything Ingenuity does from here on out will help Perseverance achieve its goals, but any useful information it can offer is a kind of welcome bonus. He noted that aerial images Ingenuity snapped during a recent flight may be of interest to the researchers who work on Perseverance.

Ingenuitys time is expected to wrap up at some point this August, after which point it will be left behind. Until then, it will remain in the general vicinity of Perseverance, which serves as a kind of communication hub that connects it to researchers on Earth.

Regardless of what becomes of Ingenuity, the helicopter has already achieved an objectively impressive goal. We actually have an operating helicopter on Mars, and its doing its job fabulously, Grip said.

After many Martian days, called sols, of supporting these tech demonstrations and having its myriad tools and accessories meticulously evaluated by researchers back home, Perseverance is ready to kick off its own scientific journey.

The team on Earth has been transmitting software updates that enable crucial features, like improving the rovers navigation system so that its able to map and avoid any hazards that are in the way of its predetermined path.

Perseverance was built with very smart, very autonomous software, said Jennifer Trosper, deputy project manager at NASAs Jet Propulsion Laboratory. But rather than put all of its bells and whistles into action upon arrival, researchers instead took a more cautious approach that involved taking baby steps to make sure everything was working properly.

So far, the rover is looking good and is expected to collect its first samples in late June or early July, once researchers can confirm key capabilities, like its auto-navigation and final sampling systems, are in order.

Perseverance is expected to pick up four times as many samples as did Curiosity, NASAs previous rover. The rover is more advanced than its predecessor, which allows it to get more done in less time and with more autonomy.

We have to be faster. We have to be more efficient. We have to drive to locations much more quickly, Trosper said. So thats what these things are enabling us to do.

At the moment, Perseverance is residing in one of the oldest parts of the lake bed that Jezero Crater once housed a lucky accident resulting from the rover landing a bit off its intended target. Its possible that the rover never would have made it to this particularly aged spot otherwise, Trosper noted.

The ancient, exposed terrain, which lies to the east of a nearby sand dune field, may offer some of the oldest samples Perseverance gets on its mission.

When it comes to geological sampling, older is better because, Trosper explained, geology is just layers of information that tells you what happens over time. Samples from this location should help answer questions about the farthest reaches of Jezeros primordial past.

Being able to get samples from this very old part of the crater is really important to making the whole story fit together, she added. Its a significant piece of the puzzle.

Perseverance is equipped with tools that will allow researchers to examine the rocks it comes across and determine which ones are worth sampling. When faced with a rock of interest, Perseverances drill can use one bit to abrade, or gently shave down, part of its surface, and another to blow a puff of air that removes the resulting dust. The rovers remote science instruments can then determine the elemental composition of the rock itself, and what information it might hold.

Sedimentary rocks are particularly useful in the lakebed because theyre more likely to have captured evidence or biosignatures of ancient life, if any ever existed there.

Igneous rocks, according to NASA, act as geological clocks that can help researchers map a more precise timeline of how the local landscape formed billions of years ago.

For Trosper, Perseverances high-tech capabilities are just as exciting as the mysteries its set out to solve.

Obviously the science itself is phenomenal, because this is the best place on Mars to look for evidence of ancient microbial life, and were here, Trosper said. But the [rovers] autonomy is also one of the hallmarks of this mission that I really am excited about.

China’s Mars rover spotted on the surface by orbiting spacecraft – CNET

This before and after set of images shows the landing site of the Zhurong rover in Utopia Planitia on Mars. The rover is the smaller of the two dots in the upper right-hand corner.

There's a long tradition of orbiting spacecraft looking down on Mars and picking out the tiny machines on the surface below. The latest entry in this lineage comes from China's Tianwen-1 mission. The orbiter snapped a picture of the Zhurong rover and its lander on June 2.

The China National Space Administration shared a look at the landing zone in Utopia Planitia, a broad plains region, on Monday. China is only the second nation to operate a rover on Mars, after the US.

From the lab to your inbox. Get the latest science stories from CNET every week.

The rover and lander can be seen as small specks near each other in the top right-hand side of the image. Zhurong is the lower of the two dots. The other notable spots are where parts of the landing system, including the parachute and heat shield, landed.

The Zhurong rover is the smaller dot just below the lander.

"The dark area surrounding the landing platform might be caused by the influence of the engine plume during landing," CNSA said in a statement. "The symmetrical bright stripes in the north-south direction of the landing platform might be from fine dust when the landing platform emptied the remaining fuel after landing."

Images from the Tianwen-1 mission -- which consists of the spacecraft, the lander and the rover -- have been few and far between. Most recently in late May, we saw some wheel tracks left by the rover's first moves across the dusty and rocky ground.

The solar-powered rover has been rolling since May 22 and has an expected life span of around three months. It's gathering images of the surface and studying the planet's subsurface as it looks for signs of ice below.

CNSA doesn't typically release as much information on its space exploits as we're used to seeing from agencies like NASA and the European Space Agency, so tidbits like the orbital images give us an enticing glimpse into the mission.

WSAV NOW Weather: Rare clouds spotted on Mars – WSAV-TV

SAVANNAH, Ga (WSAV) The Curiosity Rover captures pictures of the Martian skyline and atmosphere every day. However in late May, Curiosity captured rare clouds in the sky using its in color Mast camera. These types of clouds dont occur that often in the very thin and dry atmosphere. Most clouds are typically found at the Planets equator when Mar is farthest from the Sun.

Two Earth years ago, NASA scientists noticed clouds forming earlier than expected. They made sure Curiosity would be set up to start documenting these rare clouds as soon as they appeared in January. The Rover captured images of wispy clouds of ice crystals.

Most Martian clouds are no higher than about 37 miles in the sky and are made of water ice. These rare clouds are at higher altitudes, at colder temperatures, and are most likely made of frozen carbon dioxide.

The Curiosity team was able to pin point the height of the rare clouds by following the position of the sun in the sky and the color of the Noctilucent clouds. The high level clouds glowed brighter as the sun was high in the sky. As the sun began to drop below their altitude, the ice crystals would darken. This is one useful way they can determine how high the clouds are.

Another cool discovery NASA found by looking at these rare clouds is that they have a pastel shimmer to them when the sun is at certain positions. These are called Mother of Pearl clouds. They tend to have a light colorful shimmer like a pearl would have. The shimmer comes from the cloud particles growing at the same rate and growing to the same size.

NASA scientists were able to solve the mystery of what is creating a long stream of thin clouds coming from a now-existent volcano. Arsia Mons is south of the Martian equator. These mysterious clouds formed seasonally during spring and summer morning due to the combination of orographic lift of the existent volcanos height (12 miles tall) and meteorological conditions.

For comparison, Mount Everest is only about 5 1/2 miles tall. The spring and summer morning weather conditions plus the height also explains why the clouds would dissipate by midday. Much like how morning fog can form here on Earth but clear by midday.

The flowing cloud formation can stretch as long as 1,100 miles and around 93 miles wide. The Mars Express Visual Monitoring Camera caught the formation on the Red Planet. The images from the camera showed the clouds forming every spring and summer morning.

NASA’s Perseverance Mars Rover heads south to search for Signs of Life in Jezero Crater’s Lakebed – Clarksville, TN Online – Clarksville Online

Pasadena, CA On June 1st, NASAs Perseverance Mars rover kicked off the science phase of its mission by leaving the Octavia E. Butler landing site. Until recently, the rover has been undergoing systems tests, or commissioning, and supporting the Ingenuity Mars Helicopters month of flight tests.

During the first few weeks of this first science campaign, the mission team will drive to a low-lying scenic overlook from which the rover can survey some of the oldest geologic features in Jezero Crater, and theyll bring online the final capabilities of the rovers auto-navigation and sampling systems.

By the time Perseverance completed its commissioning phase on June 1st, the rover had already tested its oxygen-generating MOXIE instrument and conducted the technology demonstration flights of the Ingenuity helicopter. Its cameras had taken more than 75,000 images, and its microphones had recorded the first audio soundtracks of Mars.

We are putting the rovers commissioning phase as well as the landing site in our rearview mirror and hitting the road, said Jennifer Trosper, Perseverance project manager at NASAs Jet Propulsion Laboratory in Southern California.

Over the next several months, Perseverance will be exploring a 1.5-square-mile [4-square-kilometer] patch of the crater floor. It is from this location that the first samples from another planet will be collected for return to Earth by a future mission, Trosper stated.

The science goals of the mission are to study the Jezero region in order to understand the geology and past habitability of the environment in the area, and to search for signs of ancient microscopic life. The team will identify and collect the most compelling rock and sediment samples, which a future mission could retrieve and bring back to Earth for more detailed study.

Perseverance will also take measurements and test technologies to support the future human and robotic exploration of Mars.

Spanning hundreds of sols (or Martian days), this first science campaign will pursue all of the missions science goals as the rover explores two unique geologic units in which Jezeros deepest (and most ancient) layers of exposed bedrock and other intriguing geologic features can be found.

The first unit, called the Crater Floor Fractured Rough, is the crater-filled floor of Jezero. The adjacent unit, named Stah (meaning amidst the sand in the Navajo language), has its fair share of Mars bedrock but is also home to ridges, layered rocks, and sand dunes.

To do justice to both units in the time allotted, the team came up with the Martian version of an old auto club-style map, said JPLs Kevin Hand, an astrobiologist and co-lead, along with Vivian Sun, of this science campaign. We have our route planned, complete with optional turnoffs and labeled areas of interest and potential obstructions in our path.

Most of the challenges along the way are expected to come in the form of sand dunes located within the mitten-shaped Stah unit. To negotiate them, the rover team decided Perseverance will drive mostly either on the Crater Floor Fractured Rough or along the boundary line between it and Stah. When the occasion calls for it, Perseverance will perform a toe dip into the Stah unit, making a beeline for a specific area of interest.

The goal of the campaign is to establish what four locations in these units best tell the story of Jezero Craters early environment and geologic history. When the science team decides a location is just right, they will collect one or two samples.

Starting with the Crater Floor Fractured Rough and Seitah geologic units allows us to start our exploration of Jezero at the very beginning, said Hand. This area was under at least 100 meters [328 feet] of water 3.8 billion years ago. We dont know what stories the rocks and layered outcrops will tell us, but were excited to get started.

The first science campaign will be complete when the rover returns to its landing site. At that point, Perseverance will have traveled between 1.6 and 3.1 miles (2.5 and 5 kilometers) and up to eight of Perseverances 43 sample tubes could be filled with Mars rock and regolith (broken rock and dust).

Next, Perseverance will travel north then west toward the location of its second science campaign: Jezeros delta region. The delta is the fan-shaped remains of the confluence of an ancient river and a lake within Jezero Crater. The location may be especially rich in carbonates minerals that, on Earth, can preserve fossilized signs of ancient life and can be associated with biological processes.

From Sojourner to Spirit and Opportunity to Curiosity to Perseverance, Matt has played key roles in the design, construction, and operations of every Mars rover NASA has ever built, said Trosper. And while the project is losing a great leader and trusted friend, we know Matt will continue making great things happen for the planetary science community.

A key objective for NASAs Perseverance Mars Rovers mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planets geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.

The Mars 2020 Perseverance mission is part of NASAs Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.

JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.

Sols 3142-3143: Workspace of the Imagination NASA’s Mars Exploration Program – NASA Mars Exploration

This image was taken by Left Navigation Camera onboard NASA's Mars rover Curiosity on Sol 3140. Credits: NASA/JPL-Caltech Download image

Another successful long drive brought us to another wondrous workspace, filled with textures and structures the team could not wait to explore. The engineers made it possible to get the arm to two targets for MAHLI and APXS analyses. The first, Minzac, is a small area of bedrock relatively free of veins and nodules. The second, Terrasson Lavilledieu, which in France is home to The Garden of the Imagination (a contemporary public park designed to represent the history of gardens), is a patch of gray vein material opportunistically lying flat for easy arm access. This vein material was sufficiently interesting to the team that it will also be the subject of Mastcam multispectral and ChemCam passive observations at the target Videix. Videix and Terrasson Lavilledieu are in very close proximity on the vein target, unlike their counterparts in France.

ChemCam will shoot across a nodule and bedrock at the target Vayres, and Mastcam will get another multispectral observation at this same target. The mid- and farfield terrain was as interesting as our workspace, and garnered imaging attention from both Mastcam and ChemCam. Mastcam will acquire a small mosaic of Larzac, a three dimensional jumble of intersecting veins standing up above the bedrock, a ten-image mosaic of the foot of a ridge extending down from higher on Mount Sharp, and a larger mosaic stretching from the workspace along the starboard side of the rover. ChemCam will acquire a long distance RMI mosaic of a butte in the sulfate unit many kilometers up the road from our current position.

As we sit at our current workspace, as we drive to our next one, and after we arrive there, DAN will ping the ground beneath the back wheels of the rover, tracking the H signal within the subsurface. RAD and REMS run regularly throughout the plan, continuing to build their steady records of the radiation and weather conditions in Gale. Navcam will acquire dust devil and cloud movies on the first sol of the plan, and both Navcam and Mastcam will measure the amount of dust in the atmosphere with images on second sol of the plan.

Adam Mars-Jones He blinks and night is day: ‘Light Perpetual’ LRB 17 June 2021 – London Review of Books

Light Perpetual starts with a description of a V2 about to explode on a Saturday in 1944. The tone is one of uneasy technological rapture: a thread-wide front of change propagating outward from the electric detonator, through the heavy mass of amatol. Francis Spufford has written about rockets before, in his non-fiction, engaging imaginatively with the Russian space race in Red Plenty and playing the V2 campaign at least partly for comedy in Backroom Boys, where he assessed the impact on morale of the V2 in Lowestoft. It was nil: thanks to the inaccuracy of the weapons sent against them, the people of Lowestoft had no idea they were targets.

Here the point of impact (target is exactly the wrong word for so approximate a missile) is a crowded Woolworths in South-East London. The place and time correspond with a particularly terrible missile strike on New Cross on 25 November 1944. The novel is a sort of counter-history, imagining that five of the children killed on that day escaped unharmed, and charting the lives that they might have gone on to lead. Although Spufford makes clear in his acknowledgments that the book is partly written in memory of the children who died in the New Cross attack, he also insists that Alec, Vern, Jo, Val and Ben are invented souls without real-life counterparts, just as Bexford the fictional London borough in which the novel is set is not New Cross.

The children are unprivileged rather than underprivileged and the narrative chronicles a range of opportunities for this socially homogenous group one that earlier generations could hardly have imagined. There is sociological truth to this, though theres also the sense of a writer trying to bring as much of the world as possible into a book that is remarkably ambitious for its size. The twin girls, Jo and Val, lead almost caricaturally contrasting lives, determined at least in part by their different reactions to growing up in a family without men. Jo savours her independence while Val is mesmerised and then entrapped by a masculinity that turns out to be almost purely toxic. Jo has a career as a backing singer for a British pop star who has made it big in the United States, an ex-lover with whom her connection is never quite broken. She doesnt have the push to turn herself into a solo artist, but enjoys the consolation prize of a little house with its own little crease in the hillside filled with the deep green shade of pines and succulents, bamboo and yucca: the California green that can make you forget the California brown all around it. Of all the books characters, Jo makes the most determined attempt to escape the pull of London, and it doesnt last. Val, meanwhile, never thinks of leaving, and acts as a sort of den mother to a group of racist thugs, some of them all too sincere in their belief in their mission and in her man, Mike, the only beautiful thing in her life, as well as being the cause of all the ugly ones.

To choose a group for its representative quality, its ordinariness, implies a recognition of individual limitation. But fiction chafes against ordinariness. Jo has the advantage an advantage in a novel at least of synaesthesia, with sounds bleeding into colours in her head: Under the bridge at the streets end a train rushes by: a scuffing of rust brown at the hushs edge, and then a long feathering liquid streak of purple across it. Theres no danger of Jo herself lacking colour. Ben, an outsider in the book partly by virtue of being the youngest, has his visual perceptions rendered with at least as much intensity. The first time he goes to a football match, aged seven, his gaze strays upwards:

With all this noisy air open round him Ben follows the brightness up, and up. He sees the London smoke is only a footstool. Above, the rain as it leaves mounts in a curving wall, immense, slate grey, slate purple. An anvil, pulling back. At the very top, it cauliflowers. It goes to bumps and lumps and smoothed-out tiny battlements too complicated for your eyes, but all crisp and clear.

Even in his first appearance, on the day of the V2 detonation that the book cancels, he is described as looking slightly mazed, as usual. He cant be more than two. His later history suggests a predisposition to obsessive thoughts and, as at the football match, he is always shifting his focus away from the world around him. He doesnt notice the goal that everyone else is cheering, dwelling instead on the point of gold the ball made when the sun caught it as it flew its an epiphany or a seizure or a bit of both. The conventions in play are similar to those in Updikes Rabbit books, where the protagonists lack of large-mindedness does not prevent Updike from imagining him largely, as Roger Sale put it in the New York Times, though they are stretched when very literary formulations are meant to be Bens unspoken words: Each tree stands in a ragged oval of leaf-fall, summers discarded yellow petticoat. This seems too sharply eloquent, at a time when his thoughts are described as being wrapped in dustsheets, like furniture in an unused room.

As far as large-mindedness goes, Vern is a non-starter. Its not easy to find the sparkle in a life devoted to acquisitiveness and double-dealing, to amoral manoeuvres that are shrewd but not shrewd enough. Spufford gives Vern a perverse streak of sensitivity in one supremely aestheticised area. He has a responsiveness to opera that makes it hard, when he spots Maria Callas in a restaurant, to concentrate on tricking a footballer into accepting liability for any debts his latest enterprise runs up. Out of the chrysalis of the usual him has crept this damp-winged other Vern, who only wants to stare even if the footballer, following Verns eyes, can see only a skinny, foreign-looking woman in her forties.

This aspect of Verns character is introduced early enough to substantiate later scenes, when for instance he stages a lavish banquet for himself on the lawn at Glyndebourne, the waiter cooking an omelette aux fines herbes over a silver spirit lamp, its blue flame almost invisible in the June sunlight, the aroma of chervil and butter advertising the success of the outer Vern, while the inner one waits for the rapture of curtain up. At other times he is called on to channel abstract thought, a cool examination of his own instinctive recoil from the old houses he specialises in renovating and selling on:

Chewed up by time, used up by time, in a funny way contaminated by time, as if all the lives lived in this heavy rookery for humans, first the posh ones with the wigs and ball dresses, then all the ever poorer clerks and labourers and flotsam from around the world, with their coughing children, and their meals cooked on gas rings in dirty corners, have made it impossible for there ever to be a fresh start here, a new beginning, there being so much living and dying already ingrained here, stuck to surfaces like grease, laid down in scungy thicknesses.

He even contemplates the idea that these buildings will still be standing when we are removed as mortal rubbish. The sense that Vern is a pint pot having a quart of insight poured into it is inseparable from the way this unspectacularly ambitious book works as a whole, as it seeks not only to track five individuals across two-thirds of a century but to sketch their city on a grander time scale. At one point, driving past Eltham on the A20, listening to Joan Sutherland in Lucia di Lammermoor on his cars sound system, what Vern sees comes close to a rival aria:

The 1930s semis with their triangular raised eyebrows; the Edwardian schools and the brutalist ones; the corner shops now selling lentils and fenugreek; the railway arches filled with little garages; everywhere the plane trees, the sycamores, the horse chestnuts, so wet now they stand like pulpy chandeliers, dribbling and drooling, filtering the light away so the pavements are dim beneath.

Some writers who started their careers with non-fiction are drawn to the freedom the novel offers, and this must in some way be true of Spufford, but the spirit of scrupulousness in his research carries over, deepening invention rather than confining it. Readers of his first novel, Golden Hill, could almost believe they understood the intricacies of 18th-century American monetary practice, unless called on to explain it themselves. He has admitted to a tiny slip in that book, the mention of liquorice as a confection rather than a medicinal root before the apothecary George Dunhill had the idea of adding sugar to it. A chance encounter on my part with an episode of the Antiques Roadshow suggests that a characters having trouble sleeping thanks to a loose spring is also (undamagingly) anachronistic for 1745.

Readers of Light Perpetual can get precise and unfussy answers to any number of questions. Who is responsible for Mikes version of power dressing? Val, the friend of British nationalists, of course.

There arent enough members of the white races vanguard for the uniforms to come from a factory. They have to be home-made. The blue BM crossed-circle came as a machine-embroidered patch, but she was the one who had to get it to work on a khaki shirt, who had to make the jacket and the armband, to improvise the Sam Browne belt He got photographed in it for his membership card, and now it hangs in the wardrobe in a dry-cleaning bag.

What makes of car would be driven by the first, semi-bohemian wave of gentrifiers in South-East London? Elderly green Saab, mossy Audi, silver Volvo estate missing a hubcap. What is the music like on the Assemblies of Salvation circuit of evangelical churches? Gospel settings of old hymns, and a touch of Highlife for those nostalgic for Ibadan, and new worship songs from the sacred (but still funky) end of soul. What sources of funding could an enterprising head teacher hope to tap in the first decade of this millennium? SEAL money, EiC money, EMAG money, LIG money, NDC money, NRF money. Nowhere does the virtue of compression become the vice of density or cross the line into knottiness of texture.

The paths of characters who were close as children hardly cross in later life. As a result, the single episode in which a main character intervenes in the life of another has an almost allegorical quality, something Spufford is unlikely to want if he did, he would have indulged the trope more freely. Alecs father was in the print, and Alec follows him into the business. In one lovely, lucid pageSpuffordhymns the compositors trade. Alec joyfully immerses himself in the physicality of work, held in a womb of mechanical noise, to be monitored with some spare fraction of a busy mind, because a variation or blockage in it could be a sign that Mama Linotype is about to squirt molten metal at your legs. By 1979, Alec is on strike. It turns out that he has committed his life to an obsolete technology. Now he must acquire some domestic skills while his wife, Sandra, goes out to work. Theres a knock on the door, and he recognises Vern, who is also at a low ebb, in search of any council tenant ill, old or lonely who can be persuaded to sell. With discounts available for council house buyers, at last theres a government thats on his side the same government that is busy crushing unions like Alecs. A chance remark of Alecs alerts Vern to the gentrifying trend on Bexford Rise. This is news to Vern, but hes not the type to waste time. The reader is offered a tableau: Opportunism superseding Principle.

The outward-facing aspect of the novel extends to the way its characters pay attention to people outside their own social groups. I remember Angela Carter saying that she warmed to any novel (I think she mentioned Maureen Duffys Capital) whose characters used public transport it made a nice change. Late in life, Alec makes vivid mental notes on his fellow passengers while travelling on the tube (Square-faced pasty white boy, with swags of beard at the corners of his jaw, like a playing-card kings). At the same age Jo, riding a 54 bus, observes white girls whose thongs show above the back of their low-rise jeans (God, what a stupid fashion) and black boys with heads shaved into cryptic sigils, getting on and off in obedience to the invisible frontiers of their postcode wars. Her favourite place on a bus has always been at the front of the top deck, enjoying that stilt-walkers sway, that giraffe-riders ungainly perch above the street. Alec imagines the future London he wont live to see, its green porcelain architecture borrowed from H.G. Wellss Time Machine a book he has never forgotten. Or the towers a kilometre high from which it will be possible to see the Channel gleaming in the sun. Or the shrunken half-drowned settlement ringed by steaming paddies. In the section describing Jos bus ride, Spufford inserts a complementary vision of the citys distant past: Bexford, Lewisham, Woolwich: permanent-sounding names for gravel beds left behind by the rivers random swinging this way and that across a basin of clay between hills, for millions of years during which there were no names, no city, no humans. Here is a speculation that cant easily be given to one of the novels characters, and so it appears as a paragraph within brackets, extraterritorial.

The initial set-up of Light Perpetual, with five figures, three male and two female, silhouetted against catastrophe, suggests an inverted version of The Bridge of San Luis Rey, Thornton Wilders critical and popular triumph of 1927. Wilder also began and ended his novel with the death of a group: five characters fall into a ravine when a fictional bridge in Peru collapses on 20 July 1714. This dramatic beginning allows Wilder to investigate the event under the symmetrical chapter headings of Perhaps an Accident and Perhaps an Intention. The early announcement of serious intention licenses him to explore playful and comic tones without fear of seeming trivial. Like the lead weights sewn into curtain hems, it makes sure the material hangs properly.

The framing device in Light Perpetual doesnt have so much to offer. Its a strange commemoration of the children who died in the New Cross Woolworths that unwrites the original disaster. The conceit of those non-deaths, announced and immediately annulled, seems to be a way of symbolically starting from zero, wiping the board clean. The novel could have followed any group of children over the same period and had as much to say about the sights, smells, sounds and social economy of a city in flux. It isnt a necessary or even an efficient way of enabling the reader to enter the narrative.

The book is structured in separate chronological sections, starting in 1949 and proceeding in leaps of fifteen years. They are announced by headings that use t to represent the time of the explosion (t + 5, t + 20 and so on), but the time scheme is arbitrary. A choice has been made to excise vast tracts of time so that what remains can be modelled with superlative fullness. Each of Updikes Rabbit novels concentrated on a single period, and Richard Ford did something similar in the sequence that began with The Sportswriter, meaning that no event need be skipped. Alec, dancing with his ex-wife, may feel that fifteen years are nothing, but fifteen years in these pages is long enough to contain a long prison sentence, subsequent rehabilitation and eventually the training required to answer phones as a Samaritan. Its long enough for a mod to become a skinhead, for a teaching career to begin and end. Its long enough for a black woman seen by her family as a QC in the making to become an MP in reality. For one of the characters, dying in a hospice, able to control the dosage of his morphine pump, time blurs and moves in jumps. People come and are suddenly gone, he blinks and night has become day or day become night. We wake to a changed world without any memory of having left it. Vicky is seriously ill with bulimia? We had no idea. Her grandfather Alec is shocked too, not having seen her for a while, but readers havent encountered Vicky since she was a toddler. When Jo refers to a toe-stubbing trip over times doorstep she is talking about a technical problem in synchronising a recording, but the phrase could be taken as a description of how the novel itself unfolds. A gap of fifteen years between sections seems to set the mesh of the net too wide.

In Seven Up!, Michael Apted chose a group of seven-year-olds and returned to his interview subjects at intervals of seven years. In 20 Sites n Years, a different sort of documentary project, Tom Phillips set out in 1973 to take pictures of twenty London streets on (roughly) the same day every year, at the same time of day and from the same position. There is only incidental human presence in the images, and at first the succession of years gives an impression of changelessness, but then there are sudden leaps, and even in the absence of drastic transformation there are nuances to be extracted, as Phillips describes: Although a quiet side street (or perhaps because of that) it seems to get dug up more frequently than any other: changes in the post-operative tar show where the latest incision has been made.

The human eye allows us to see a succession of still images projected at the appropriate speed as moving pictures. Readers of fiction have much more flexibility to generate an illusion of continuity, but at a certain point it breaks down. In his most recent novels, The Strangers Child and The Sparsholt Affair, Alan Hollinghurst introduced long gaps into the narrative in a way that requires the readers relationship with the story to be renegotiated almost from scratch (the new time period tends to bring with it new points of view, further testing the relationship). The obvious choice of fictional genre to combine coherence and a long, interrupted timespan is that undemanding form the family saga, and although it would be slightly mad to urge such a thing on writers as sophisticated and accomplished as Hollinghurst and Spufford, their solutions pose problems of their own. In Proust and Anthony Powell, the shock of character as it develops over time is situated within an immense continuity. Even so there can be a limit to what is plausible. Not every reader is convinced by the last incarnation of Powells Widmerpool, or by the transformation of Prousts Bloch or Gilberte. They would be still less persuasive if they werent part of an apparently seamless whole.

If time isnt continuous, it becomes barely recognisable. In Robert Coovers great story Going for a Beer, barely a thousand words long, the continuousness is deceptive, belonging to language and not to the experience language claims to represent. He finds himself sitting in the neighbourhood bar drinking a beer, it starts,

at about the same time that he began to think about going there for one. In fact, he has finished it. Perhaps hell have a second one, he thinks, as he downs it and asks for a third. There is a young woman sitting not far from him who is not exactly good-looking but good-looking enough, and probably good in bed, as indeed she is. Did he finish his beer? Cant remember. What really matters is: Did he enjoy his orgasm? Or even have one?

The reading brain smooths out the first slip forward in time, but they just keep coming until they cant be ignored. The effect is both rich and desolating, whether you read the story as a realistic account of the damage done to memory through alcohol, or as a wild exaggeration of inhabiting the consequences of decisions you dont quite remember making. Spufford refers to something similar in Light Perpetual when Alec, attending a family wedding, thinks of marriage as an exceptional event on precisely this basis, the astonishment of standing on the magic pivot, the trampoline of transformation, where your life is being changed and for once you know it.

In the weakest part of the novel, Ben is in his late thirties and working as a bus conductor. He is prey to obsessive thoughts (specifically, images of cannibalistic barbecue) that leave him barely able to function. Images of dripping fat and bubbling skin fill his mind, and the page fills up with the words charred ribs, first in italics and then full caps. This is new: in the 1964 episode Ben was a voluntary patient in a mental hospital, dosed up on Largactil and grateful for it, escaping awareness of an unnamed Trouble. In 1979 his misery can be blurred in the evening by dope, but must be endured during the day, and the episode ends with a one-phrase paragraph: So many days like this.

Its precisely this dailiness thats been removed from Light Perpetual, and fifteen yearliness cant take its place. Apteds seven-year gaps meant the series couldnt offer dailiness, but it did give a sense of how intractable, how chronic, things like class position and mental illness could be. When Ben next appears, in 1994, his demons have been exorcised. He is a new man, redeemed by love and faith; although his transformation is tenderly described, it seems unreal. The conjurors wand that abolishes fifteen years at a go cant also restore the magic continuity of time.

The rest is here:

Full-Length Trailer: The Rise and Fall of Mars Hill – ChristianityToday.com

When Mars Hill Church was planted in Seattle in 1996, few would have imagined where it would lead. But in the next 18 years, it would become one of the largest, fastest-growing, and most influential churches in the United States. Controversy plagued the church, though, due in no small part to the lightning-rod personality at its helm: Mark Driscoll.

By 2014, the church had grown to 15,000 people in 15 locations. But before the year was over, the church collapsed. On January 1, 2015, Mars Hill was gone.

Hosted by Mike Cosper, The Rise and Fall of Mars Hill explores the inside story of this church, its charismatic leader, and the conflicts and troubles that brought about its end. Youll hear from insiders and experts, tracing the threads of this story to so many others that shape the church today.

With cyberattacks on the rise, organizations are already bracing for devastating quantum hacks – CNBC

Amidst the houses and the car parks sits GCHQ, the Government Communications Headquarters, in this aerial photo taken on October 10, 2005.

LONDON A little-known U.K. company called Arqit is quietly preparing businesses and governments for what it sees as the next big threat to their cyber defenses: quantum computers.

It's still an incredibly young field of research, however some in the tech industry including the likes of Google, Microsoft and IBM believe quantum computing will become a reality in the next decade. And that could be worrying news for organizations' cyber security.

David Williams, co-founder and chairman of Arqit, says quantum computers will be several millions of times faster than classical computers, and would be able to break into one of the most widely-used methods of cryptography.

"The legacy encryption that we all use to keep our secrets safe is called PKI," or public-key infrastructure, Williams told CNBC in an interview. "It was invented in the 70s."

"PKI was originally designed to secure the communications of two computers," Williams added. "It wasn't designed for a hyper-connected world where there are a billion devices all over the world communicating in a complex round of interactions."

Arqit, which is planning to go public via a merger with a blank-check company, counts the likes of BT, Sumitomo Corporation, the British government and the European Space Agency as customers. Some of its team previously worked for GCHQ, the U.K. intelligence agency. The firm only recently came out of "stealth mode" a temporary state of secretness and its stock market listing couldn't be more timely.

The past month has seen a spate of devastating ransomware attacks on organizations from Colonial Pipeline, the largest fuel pipeline in the U.S., to JBS, the world's largest meatpacker.

Microsoft and several U.S. government agencies, meanwhile, were among those affected by an attack on IT firm SolarWinds. President Joe Biden recently signed an executive order aimed at ramping up U.S. cyber defenses.

Quantum computing aims to apply the principles of quantum physics a body of science that seeks to describe the world at the level of atoms and subatomic particles to computers.

Whereas today's computers use ones and zeroes to store information, a quantum computer relies on quantum bits, or qubits, which can consist of a combination of ones and zeroes simultaneously, something that's known in the field as superposition. These qubits can also be linked together through a phenomenon called entanglement.

Put simply, it means quantum computers are far more powerful than today's machines and are able to solve complex calculations much faster.

Kasper Rasmussen, associate professor of computer science at the University of Oxford, told CNBC that quantum computers are designed to do "certain very specific operations much faster than classical computers."

That it is not to say they'll be able to solve every task. "This is not a case of: 'This is a quantum computer, so it just runs whatever application you put on there much faster.' That's not the idea," Rasmussen said.

This could be a problem for modern encryption standards, according to experts.

"When you and I use PKI encryption, we do halves of a difficult math problem: prime factorisation," Williams told CNBC. "You give me a number and I work out what are the prime numbers to work out the new number. A classic computer can't break that but a quantum computer will."

Williams believes his company has found the solution. Instead of relying on public-key cryptography, Arqit sends out symmetric encryption keys long, random numbers via satellites, something it calls "quantum key distribution." Virgin Orbit, which invested in Arqit as part of its SPAC deal, plans to launch the satellites from Cornwall, England, by 2023.

Some experts say it will take some time before quantum computers finally arrive in a way that could pose a threat to existing cyber defenses. Rasmussen doesn't expect them to exist in any meaningful way for at least another 10 years. But he's not complacent.

"If we accept the fact that quantum computers will exist in 10 years, anyone with the foresight to record important conversations now might be in a position to decrypt them when quantum computers come about," Rasmussen said.

"Public-key cryptography is literally everywhere in our digitized world, from your bank card, to the way you connect to the internet, to your car key, to IOT (internet of things) devices," Ali Kaafarani, CEO and founder of cybersecurity start-up PQShield, told CNBC.

The U.S. Commerce Department's National Institute of Standards and Technology is looking to update its standards on cryptography to include what's known as post-quantum cryptography, algorithms that could be secure against an attack from a quantum computer.

Kaafarani expects NIST will decide on new standards by the end of 2021. But, he warns: "For me, the challenge is not the quantum threat and how can we build encryption methods that are secure. We solved that."

"The challenge now is how businesses need to prepare for the transition to the new standards," Kaafarani said. "Lessons from the past prove that it's too slow and takes years and decades to switch from one algorithm to another."

Williams thinks firms need to be ready now, adding that forming post-quantum algorithms that take public-key cryptography and make it "even more complex" are not the solution. He alluded to a report from NIST which noted challenges with post-quantum cryptographic solutions.

In Quantum Physics, Everything Is Relative – The New York Times

The conceptual breakthrough initiated by Heisenberg (who was mentored by Niels Bohr), and firmed up with contributions from Max Born, Wolfgang Pauli, Paul Dirac, Erwin Schrdinger and others, makes it clear that the world of the very small that of photons, electrons, atoms and molecules obeys rules that go against the grain of our everyday physical reality.

Take an electron that is emitted at Point A and is detected at Point B. One would assume that the electron follows a trajectory, the way a baseball does from a pitchers hand to a catchers mitt. To explain experimental observations, Heisenberg rejected the notion of a trajectory for the electron. The resulting quantum theory deals in probabilities. It lets you calculate the probability of finding the electron at Point B. It says nothing of the path the electron takes. In its most austere form, quantum theory even denies any reality to the electron until it is detected (leading some to posit that a conscious observer somehow creates reality).

Since the 1950s, scientists have tried to make quantum theory conform to the dictates of classical physics, including arguing for a hidden reality in which the electron does have a trajectory, or suggesting that the electron takes every possible path, but these paths are manifest in different worlds. Rovelli dismisses these attempts. The cost of these approaches is to postulate a world full of invisible things.

Instead, in Helgoland Rovelli explains his relational interpretation, in which an electron, say, has properties only when it interacts with something else. When its not interacting, the electron is devoid of physical properties: no position, no velocity, no trajectory. Even more radical is Rovellis claim that the electrons properties are real only for the object its interacting with and not for other objects. The world fractures into a play of points of view that do not admit of a univocal, global vision, Rovelli writes. Or, as he puts it, Facts are relative. Its a dramatic denunciation of physics as a discipline that provides an objective, third-person description of reality.

This perspective blurs the distinction between mental and physical phenomena. Both are products of interactions between parts of the physical world, Rovelli says. In arguing that the mind is itself the outcome of a complex web of interactions, Rovelli takes on dualists who distinguish between the mental and the physical and nave materialists who say that everything begins with particles of matter with well-defined properties.

CU Boulder the site of 53-year-old report on UFOs. What do the findings say? – CU Boulder Today

Later this month, U.S. intelligence agencies are expected to present to Congress a highly anticipated unclassified report detailing what they know about unidentified flying objects (UFOs).

According to unnamed officials reported to have been briefed on its contents, the task forcedid not find evidence that the unexplained aerial phenomena (likened to UFOs) that Navy pilots have witnessed in recent years are alien spacecrafts. But the report does not definitively say they aren't.

One of the last government-commissioned reports on UFOs was conducted right here at CU Boulder and resides in the archives at University Libraries. Edward Condon, a former professor of physics and astrophysics, was given $300,000 to produce a thousand-page report named The Scientific Study of Unidentified Flying Objects,or the Condon Report, as it became known.

Heather Bowden, head of Rare and Distinctive Collections, has preserved and reviewed the Condon Reportand spoke with CU Boulder Today about what it found.

Head of Rare and Distinctive Collections Heather Bowden

Edward U. Condon (190274), a former professor of physics and astrophysics and fellow of the Joint Institute of Laboratory Astrophysics (JILA), was a prominent theoretical physicist who made substantial contributions in academia, industry and government. He had a major impact in the development of scientific fields such as quantum mechanics, nuclear science and electronicsbut was most known for his report on UFOs.

The Condon Report was commissioned by the United States Air Force in the mid-1960s with the aim of producing an unbiased scientific investigation into the possibility that unidentified flying objects may be of extraterrestrial origin. The decision to conduct the study came from a March 1966 report from an ad hoc committee of the Air Force Scientific Advisory Board tasked with reviewing this issue.

The collection contains documents, journals, research papers, international newsletters, film reels of suspected sightings and books gathered during Condon's commissioned study.

In the first section, Condon reported, Our general conclusion is that nothing has come from the study of UFOs in the past 21 years that has added to science knowledge, meaning the researchers involved in the project did not find conclusive evidence there have been sightings of UFOs that were crafted by remote galactic or intergalactic civilizations.

The 2021 government-commissioned UFO report came to a similar conclusion, according to unnamed sources cited in articles from The New York Times and CNN, but did not rule out the possibility that alien life exists.

How studying UFOs could lead to new scientific breakthroughs

This month, a Pentagon task force will release a long-awaited report digging into a topic typically relegated to science fiction movies and tabloids: unidentified flying objects. Professor Carol Cleland talks about the report and why scientists should take weird and mysterious observations seriously.

Im always most fascinated by the handwritten materials and scraps of notes that accompany published pieces like the report, because it lends a human element to something that could otherwise be considered clinical and dry.I also think the film reels would be fascinating to watch.

Students can access materials from the collection when Norlin Library reopens this fall by contacting rad@colorado.edu to schedule an appointment in the Rare and Distinctive Collections (RaD) Reading Room. Students can also check out additional UFO-related University Libraries resources online.

British innovation will be key to success of merger dubbed the ‘Apple of quantum computing’ – Sky News

Quantum computing is one of those technologies that, like artificial intelligence, has been attracting the interest of investors for some time - even though few can actually explain what it involves.

The technology, put very simply, involves harnessing quantum physics - the branch of the science that seeks to describe and explain how and why objects behave and move in the way that they do - to store data or perform computations to a vastly more efficient degree than traditional computers.

Quantum computers are said to be able to operate millions of times faster than existing ones.

A number of governments around the world are pumping capital into the sector in the hope of establishing a lead in the field. They include Germany which, in June last year, announced a 2bn (1.7bn) investment into two new quantum computers.

China, meanwhile, is setting up a national laboratory for quantum information sciences.

But the technology has also been the topic of much debate in investment circles.

Supporters believe it has the potential to transform many industries and sectors, including genetic medicine, pharmacology, financial services and materials development.

Sceptics argue that its vast potential may take many years, if ever, to be realised.

Wednesday, however, brought news of a deal that suggests quantum computing may indeed be on the verge of a breakthrough that could see it being applied more widely across business and industry.

Cambridge Quantum Computing, a British business founded in 2014, announced it is to combine with the quantum solutions arm of the US industrial giant Honeywell.

The pair said the combined business would be "extremely well-positioned to lead the quantum computing industry by offering advanced, fully integrated hardware and software solutions at an unprecedented pace, scale and level of performance to large high-growth markets worldwide".

Honeywell will be the majority shareholder of the new company, with CQ's shareholders, including Ilyas Khan, its founder and chief executive, owning just over 45% of the business.

Mr Khan said that he believed a breakthrough in the quantum computing had already arrived.

He told Sky News: "I think the tipping point was probably in the last 18 months. China, the United States, the United Kingdom, of course, have major programmes and lots of countries and companies have said that they face an existential risk if they don't get quantum computing right.

"In terms of applications, things that we will use on a day to day basis, I think a good analogy is mobile phones - at the end of the 1980s, before they arrived, nobody really knew that they're going to use them and of course, when they did arrive, the markets and their usage exploded.

"I would imagine that later on this year things like cyber security, for example, will be offering unhackable keys using the quantum computer, and it will begin to be more and more useful. Maybe the more esoteric uses are probably a couple of years away, machine learning, for example, [or] material discovery."

He said the combined business would be a "global powerhouse" capable of creating and commercialising quantum solutions that address "some of humanity's greatest challenges".

British tech start-ups are often accused of selling out too early but Mr Khan, who will lead the combined business, could not be described as such.

He added: "The UK is the leader in quantum and this is the first time since the Second World War that a major technology initiative is not being driven by Silicon Valley. We are a software and an algorithm provider and the merger creates an integrated business.

"[It will be] what I would describe as an Anglo American, actually a global business. The characterisation of a sell-out, I think, is probably not one I would agree with."

Honeywell will be investing between $270m (190m) and $300m (211m) in the new venture and Mr Khan said this money would be invested, predominantly, in people.

At the start of its life, the enlarged business will be employing around 350 people, of whom 200 are scientists - more than half of them boasting doctorates in disciplines such as chemistry, physics and maths.

Mr Khan went on: "This is a business where we are in scaling and growth mode - so it's primarily people. We will probably grow quite rapidly as far as the numbers are concerned, both in the United Kingdom, and in the United States, and then a reasonable amount of that capital will be in continuing to increase the capacity of the quantum computers. We have the world's best performing computer right now - and we will be deploying that for customer usage over the course of the next few years."

Hinting at a forthcoming stock market flotation of the business, Mr Khan said there would also be a fund-raising at some point in the near future, in which outside investors would be able to buy a stake in the business.

He declined to say what valuation had been put on Cambridge Quantum under the transaction but said some numbers would be released "over the course of the next week or two".

Mr Khan went on: "This is something which is obviously something that I'm very proud of. It's a British winner. The United Kingdom is the leader in this. We are the world's leader and, of course, consequently very valuable."

That reluctance to talk specific numbers is, perhaps, understandable.

Barron's, the influential US financial publication, has already suggested that the enlarged business could be the 'Apple of quantum computing' because the deal brings together Honeywell's expertise in quantum hardware with Cambridge Quantum's expertise in software and algorithms - emulating the way Apple straddles hardware, operating systems, and software applications. Honeywell itself has said that quantum computing will one day be a trillion dollar-a-year industry.

The deal marks another twist in what has been an inspiring story.

Born in Haslingden, in Lancashire, Mr Khan's father was a bus driver and he was brought up in what he told the Lancashire Telegraph in 2009 was a "two up, two down terrace". Educated at Haslingden Grammar School and University of London School of Oriental and African Studies, he want into banking on graduating, spending 20 years of his career in Hong Kong.

He first came to public attention when, in 2009, he rescued Accrington Stanley FC and later served as its chairman for three years. He has reportedly sunk more than 2m of his own money into the club over a 20-year period.

On returning to the UK he joined the University of Cambridge's Judge Business School and chairman of the Stephen Hawking Foundation and it was a comment from the late Professor Hawking, a friend, who prompted him to start Cambridge Quantum.

He told The Quantum Daily last year: "The prompt really came from a comment that Stephen made to me in a meeting that we were attending and Stephen said 'this is for real'. This really opened my eyes."

It is just possible that those investors still sceptical about quantum computing may well have had their eyes opened, too, following this deal.

Spintronics: what you need to know about electron control – Verdict

Spintronics has already had profound impact on the computing industry and there is more to come.

The electron is a subatomic particle that plays an essential role in numerous physical phenomena like electricity and magnetism. It has been responsible for much of the technological marvels we see today.

Computers, reliant on the movement of electrons and their intrinsic charge, have ushered in a new era of innovation and societal development. However, as computers become small enough to fit on our wrists, quantum mechanics (the rules which govern subatomic physics) will soon prevent chips from getting any smaller.

The presence of electrons, and hence charge, on one side of a transistor (a semiconductor device which amplifies electric current) acts as something of an on switch representing a 1 and the lack of electrons represents a 0. But electrons dont really like staying in one place. They jump around. Soon, transistors will be so small that this becomes a problem.

Thankfully, electrons have another property that we can exploit. Its called spin, and manipulating electron spins could pave the way to the next generation of nanoelectronic devices.

Reduced power consumption, increased memory capacity, and improved processing capability can all be realised in applications from medicine to space research, with the aid of spintronics spin electronics.

What is spin?

Spin is a confusing area of physics but the essence of it is this: imagine the electron as a tiny bar magnet, with north pointing one way, and south the other. If the north side points up, it is a spin up electron, and if north points down it is spin down. This has nothing to do with the electron spinning like a billiard ball physicists do have a penchant for giving things confusing names.

What does this mean for our devices? Well, spin can be used to change how electrons flow which gives us more control.

Dr Amalio Fernandez-Pacheco, an EPSRC Early Career Fellow in the University of Glasgows School of Physics and Astronomy, describes it as like being given an extra note in a musical scale to play with.

Why does spintronics matter?

Giant magnetoresistance (GMR) is a spintronic effect whereby electric current can flow between layers of magnetic and non-magnetic material, depending on the spins of the magnetic layers. The 2007 Nobel Prize in Physics was awarded to Albert Fert and Peter Grnberg for its discovery.

GMR is at the heart of todays read heads for hard disk drives (HDDs), which manipulate the structure of the disk to store information. GMR-based read heads were introduced by IBM in 1997 and led to an increase in information density by a factor of 1000.

Random access memory (RAM), hardware that stores data temporarily, can usually only hold onto data if there is an electric current supplied. Magnetic RAM (MRAM) has been in development over the past ten years, which uses spintronic effects to allow data storage without the supply of electricity. MRAM can resist high temperatures and radiation, which has led to applications in space research and a potential future in the automotive industry.

Spintronics is set to play a key role in the development of neuromorphic computing, which aims to create artificial circuits that mimic the structure of the brain. Quantum computers, which could speed up calculations of certain tasks by orders of magnitude, can also be spin-based.

The study of spintronics encompasses a wide variety of applications and has so far proved successful in areas such as HDDs. It is the subject of intense study, and those in the tech industry should expect more spin-based revolutions in the years to come.Related Report Download the full report from GlobalData's Report StoreGet the Report

Spintronics: what you need to know about electron control - Verdict

What happened before the Big Bang? – Big Think

Let's face it: to think that the universe has a history that started with a kind of birthday some 13.8 billion years ago is weird. It resonates with many religious narratives that posit that the cosmos was created by divine intervention, although science has nothing to say about that.

If everything that happens can be attributed to a cause, what caused the universe? To deal with the very tough question of the First Cause, religious creation myths use what cultural anthropologists sometimes call a "Positive Being," a supernatural entity. Since time itself had a beginning at some point in the distant past, that First Cause had to be special: it had to be an uncaused cause, a cause that just happened, with nothing preceding it.

Attributing the beginning of everything to the Big Bang begs the question, "What happened before that?" That's a different question when we are dealing with eternal gods, as for them, timelessness is not an issue. They exist outside of time, but we don't. For us, there is no "before" time. Thus, if you ask what was going on before the Big Bang, the question is somewhat meaningless, even if we need it to make sense. Stephen Hawking once equated it with asking, "What's north of the North Pole?" Or, the way I like to phrase it, "Who were you before you were born?"

Saint Augustine posited that time and space emerged with creation. For him, it was an act of God, of course. But for science?

Scientifically, we try to figure out the way the universe was in its adolescence and infancy by going backward in time, trying to reconstruct what was happening. Somewhat like paleontologists, we identify "fossils" material remnants of long-ago days and use them to learn about the different physics that was prevalent then.

The premise is that we are confident that the universe is expanding now and has been for billions of years. "Expansion" here means that the distances between galaxies are increasing; galaxies are receding from one another at a rate that depends on what was inside the universe at different eras, that is, the kinds of stuff that fill up space.

When we mention the Big Bang and expansion, it's hard not to think about an explosion that started everything. Especially since we call it the "Big Bang." But that's the wrong way to think about it. Galaxies move away from one another because they are literally carried by the stretch of space itself. Like an elastic fabric, space stretches out and the galaxies are carried along, like corks floating down a river. So, galaxies are not like pieces of shrapnel flying away from a central explosion. There is no central explosion. The universe expands in all directions and is perfectly democratic: every point is equally important. Someone in a faraway galaxy would see other galaxies moving away just like we do.

(Side note: For galaxies that are close enough to us, there are deviations from this cosmic flow, what's called "local motion." This is due to gravity, The Andromeda galaxy is moving toward us, for example.)

Playing the cosmic movie backward, we see matter getting squeezed more and more into a shrinking volume of space. Temperature rises, pressure rises, things break apart. Molecules get broken down into atoms, atoms into nuclei and electrons, atomic nuclei into protons and neutrons, and then protons and neutrons into their constituent quarks. This progressive dismantling of matter into its most basic constituents happens as the clock ticks backward toward the "bang" itself.

For example, hydrogen atoms dissociate at about 400,000 years after the Big Bang, atomic nuclei at about one minute, and protons and neutrons at about one-hundredth of a second. How do we know? We have found the radiation left over from when the first atoms formed (the cosmic microwave background radiation) and discovered how the first light atomic nuclei were made when the universe was merely a few minutes old. These are the cosmic fossils that show us the way backward.

Currently, our experiments can simulate conditions that happened when the universe was roughly one trillionth of a second old. That seems like a ridiculously small number for us, but for a photon a particle of light it's a long time, allowing it to travel the diameter of a proton a trillion times. When talking about the early universe, we must let go of our human standards and intuitions of time.

We want to keep going back as close to t = 0 as possible, of course. But eventually we hit a wall of ignorance, and all we can do is extrapolate our current theories, hoping that they will give us some hints of what was going on much earlier, at energies and temperatures we cannot test in the lab. One thing we do know for certain, that really close to t = 0, our current theory describing the properties of space and time, Einstein's general theory of relativity, breaks down.

This is the realm of quantum mechanics, where distances are so tiny that we must rethink space not as a continuous sheet but as a granular environment. Unfortunately, we don't have a good theory to describe this granularity of space or the physics of gravity at the quantum scale (known as quantum gravity). There are candidates, of course, like superstring theory and loop quantum gravity. But currently there is no evidence pointing toward either of the two as a viable description of physics.

Physics' greatest mystery: Michio Kaku explains the God Equation | Big Think http://www.youtube.com

Still, our curiosity insists on pushing the boundaries toward t = 0. What can we say? In the 1980s, James Hartle and Stephen Hawking, Alex Vilenkin, and Andrei Linde separately came up with three models of quantum cosmology, where the whole universe is treated like an atom, with an equation similar to the one used in quantum mechanics. In this equation, the universe would be a wave of probability that essentially links a quantum realm with no time to a classical one with time i.e., the universe we inhabit, now expanding. The transition from quantum to classical would be the literal emergence of the cosmos, what we call the Big Bang being an uncaused quantum fluctuation as random as radioactive decay: from no time to time.

If we assume that one of these simple models is correct, would that be the scientific explanation for the First Cause? Could we just do away with the need for a cause altogether using the probabilities of quantum physics?

Unfortunately, not. Sure, such a model would be an amazing intellectual feat. It would constitute a tremendous advance in understanding the origin of all things. But it's not good enough. Science can't happen in a vacuum. It needs a conceptual framework to operate, things like space, time, matter, energy, calculus, and conservation laws of quantities like energy and momentum. One can't build a skyscraper out of ideas, and one can't build models without concepts and laws. To ask from science to "explain" the First Cause is to ask science to explain its own structure. It's to ask for a scientific model that uses no precedents, no previous concepts to operate. And science can't do this, just as you can't think without a brain.

The mystery of the First Cause remains. You can choose religious faith as an answer, or you can choose to believe science will conquer it all. But you can also, like the Greek Skeptic Pyrrho, embrace the limits of our reach into the unknowable with humility, celebrating what we have accomplished and will surely keep on accomplishing, without the need to know all and understand all. It's okay to be left wondering.

Curiosity without mystery is blind, and mystery without curiosity is lame.

Is This a Real Science Textbook Introduction? – Snopes.com

Advanced science textbooks are not generally known for their jocularity, but a purported image showing the introductory sentences from one such work is downright gloomy:

This chapter on Thermodynamics and Statistical Mechanics opens, according to the displayed snippet, by discouragingly informing readers that Ludwig Boltzmann, who spent much of his life studying statistical mechanics, died in 1906, by his own hand. Paul Ehrenfest, carrying on his work, died similarly in 1933. Now it is our turn to study statistical mechanics. Perhaps it will be wise to approach the subject cautiously.

These words do in fact form the beginning of the first chapter of the book States of Matter, a text by CalTech physicist David L. Goodstein, as documented by the following extract from a digital copy of the book:

For the curious, Boltzmann was an Austrian physicist whose greatest achievements were the development of statistical mechanics, and the statistical explanation of the second law of thermodynamics and whose efforts radically changed several branches of physics. Boltzmann, who is thought to have experienced bipolar disorder, hanged himself while on vacation in Italy in 1906.

Boltzmann was the doctoral adviser of Austrian/Dutch theoretical physicist Ehrenfest, the latter of whom made major contributions to the field of statistical mechanics and its relations with quantum mechanics. Apparently suffering from depression, in 1933 Ehrenfest traveled to Amsterdam, where he shot his 15-year-old son (a Down syndrome child who was living in a care facility) and then killed himself.

Perhaps it will be wise to approach the subject cautiously, indeed.

What is an Electron: Its Discovery, Nature and Everything Else | IE – Interesting Engineering

An electron is a stable and negatively charged subatomic particle that also acts as the carrier of electricity. Each electron carries one unit of negative charge (1.602 x 10-19coulomb) and has a mass of just about 1/1836th of a proton.Electrons are found both not permanently attached to atoms andwithin the nucleus.

Quantum mechanics states that electrons can not be distinguished on the basis of any intrinsic property, so all electrons have thesamemass, thesameelectric charge, and thesamespin, so they can freely interchange their positions within a system without causing a noticeable change.

The possibility of electrons was predicted by Richard Laming (1838-1851), and other scientists.Irish physicistG. Johnstone Stoney(1874) coined the term electron in 1891, to refer to the unit of charge in his experiments. In 1897, English physicist Joseph John Thomson discovered electrons while conducting experiments with cathode-ray tubes. He called electrons "corpuscles".

Thomsondirected cathode rays between two parallelaluminumplates to the end of a tube, where they could be observed as luminescence on the glass. When the top aluminum plate was negative, the rays moved down; when the top plate was positive, the rays moved up. This deflection was proportional to the difference in potential between the plates, demonstrating that cathode rays were negatively charged particles.

From this,Thomson made the following hypotheses:

Today, we know that the third hypothesis is not accurate, but this discovery of the electron revolutionized physics and paved the way for developments concerning electricity, gravitation, electromagnetism, thermal conductivity, and many other areas. For his work, Thomson was awarded the 1906 Nobel Prize in Physics.

Prior to Thomson, scientists such as Richard Fleming had previously predicted the possible existence of electrons. The ancient Greeks are said to have discovered that when amber is rubbed with fur, it attracts small objects. The Greek word for amber,elektronwas used for the force that caused this attraction.

Protons and electrons have equal, but opposite charges. Electrons are attracted to positively charged particles, such as protons. Whether or not a substance has a net electric charge is determined by the balance between the number of electrons and the positive charge of atomic nuclei. If there are more electrons than positive charges, a material is said to be negatively charged. If there is an excess of protons, the object is considered to be positively charged. If the number of electrons and protons is balanced, a material is said to be electrically neutral.

The radius of an electron is approximately 2 x 10-10cm.Neutrons and protons, together known as nucleons, form 99.9% of the total atomic massof an atom, and as compared to these particles, electrons have negligible mass value, therefore, the mass of electrons is not considered when the mass number of an atom is calculated.

The symbol for an electron is e and for proton is p+ but, interestingly, protons are not the true antiparticles to electrons. The antiparticle of the electron is the positron, whichhas an electric charge of +1 e, a spin of 1/2 (the same as the electron), and has the same mass as an electron.

Positronsare not found in nature but are formed during the decay of nuclides that have an excess of protons in their nucleus. When decaying takes place, these radionuclides emit apositronand a neutrino.

For any element, the atomic mass number is the total number of protons and neutrons in the nucleus. It is measured in the atomic mass units (amu).

Atomic Mass Number = (Number of Protons) + (Number of Neutrons)

Whereas, the atomic number is the number of protons only. For example, the atomic number of carbon is six, therefore, carbon has six protons in its nucleus and six electrons in the energy orbits surrounding the nucleus.

Electrons are described as surrounding the nucleus of an atom in shells. These are not actual structures but are regions of probability.

Atomic Number = Number of Protons

However, in the case of charged atoms also known as ions, the number of protons and electrons differ and depends on the charge on the atom. The number of neutrons for an atom can be easily calculated by subtracting the number of protons from the total atomic mass number.

Number of Neutrons = Atomic Mass Number - Number of Protons

The nature of the electric charge on any substance is defined by the number of protons and electrons in its nuclei. If the number of protons exceeds the number of electrons, then the substance is positively charged. Where there are more electrons than protons, the substance is said to have an overall negative charge. Any substance is said to be balanced or electrically neutral when the number of protons and electrons is equal.

French physicist Louis De Broglie proposed the wave nature of electrons in his 1924 Ph.D. thesis. He stated that if light and radiation can show dual behavior, then the matter can also exist as both particle and wave.

De Broglie was influenced byAlbert Einsteins theory of relativity and the photoelectric effect. Twenty years earlier, Einstein has proposedthe idea that matter on the atomic scale might exhibit the properties of a wave and a particle.This idea of the dual nature of light was just beginning to gain scientific acceptance when de Broglie extended the idea to include matter.

According to De Broglies hypothesis, any moving object, whether macroscopic or microscopic has its own wavelength, and this wavelength is inversely proportional to the size of the object.

In the years that followed, the American physicists, Clinton Davisson and Lester Germer conducted electron diffraction experiments that further confirmed the dual nature of matter given by De Broglie. In 1929, De Broglie received the Nobel Prize in Physics for his exceptional contribution to quantum physics.

Exploring The Limitations of Quantum Machine Learning – Analytics India Magazine

In Quantum computing, users can physically control parameters like Electromagnetic fields strength, frequency of a laser pulse, or others to solve problems. Thus, Quantum computers can be trained like neural networks. The biggest advantage of quantum computers is that they can produce patterns that classical systems are thought to have difficulties in producing. Therefore, its reasonable to assume that quantum computers may outperform classical computers on Machine Learning tasks. This has led to a new field called quantum machine learning.

Become AChartered Data ScientistAchieve the highest distinction in the data science professionREGISTER NOW

Quantum technologies can enhance learning algorithms. This is known as quantum-enhanced machine learning. The most common application of quantum computers in the field refers to machine learning algorithms for the analysis of data that couldnt be executed through classical computing.

Quantum Machine Learning increases the computation speed and can manage data storage done by algorithms in a programme. It extends the proof of learning by running machine learning algorithms on new computing devices- quantum computers. The information processing depends on quantum physics and its law, substantially different from computer models.

However, the field of Quantum Machine Learningrightfully still operates in the realms of science that is closer to fiction.The limitations are palpable.

Recent research at the Los Alamos National Laboratory showed that Quantum Machine Learning cannot be used to investigate processes like Quantum Chaos and terminalization. This places a big limit on the learning of any new process linked to it through Quantum computing. The study was based on a Hayden-Preskill thought experiment. A fictitious character Alice tosses her book inside the black hole.

The book was pulled out by Bob, who used entanglement to pull it out. Through any computation bringing the book back to its original state is impossible. Though the book was pulled out using quantum computing algorithms, the information was scrambled and no quantum machine learning model could unscramble the book back to its original state. The research also found out that Bob can unscramble the book by collecting a few photons from the black hole and learning its dynamics but the answer to that cannot be reached through Quantum Machine Learning.

The size of the system determines the scalability and the difficulty in problem-solving increases exponentially when the problem is complex or data is large. The research proves that though Quantum computing is the solution to problems it has its limitations and challenges due to its dependence on raw physics and the unadvanced nature of other technologies that help in the hardware and software development of quantum computers on which complex algorithms can be created and run.

The frequent challenge that troubles researchers is isolation. Quantum decoherence can be caused by heat and light, when subjected to such conditions qubits can lose their quantum properties like entanglement that further leads to a loss in data stored in these qubits. Secondly, rotations in quantum computers logic gates are prone to error and these are also crucial to change the state of the qubit. Any wrong rotation can cause an error in the output. The requirement of computers with a greater circuit length and error correction( with redundancy for every qubit) is also crucial for the field of quantum machine learning.

The developer of algorithms for Quantum computers has to be concerned about their physics. While a classical algorithm can be developed along the lines of the Turing machine, to develop an algorithm for Quantum computers, the developer has to base it along the lines of raw physics with no simple formulas that would link it to logic.

The critical issue in such a design is always scalability. Designing a program to operate on larger data with more processing power. Very little information is available to develop such algorithms for quantum computing. Most of the development is therefore intuitive. Most known Quantum algorithms suffer from a proviso of specific simulations that limit their practical applicability and it becomes difficult to develop models that can have a significant impact on machine learning. The third limitation in quantum computing is that the number of qubits one can have on a quantum circle is limited. Though these limitations are applicable to quantum computing in general, the augmentation of fields such as machine learning can grab more eyeballs and push the field in the right direction.
