Why the attack on JNU is hard to digest – Gulf News

It was the autumn of 1994. The campus of Jawaharlal Nehru University (JNU) on the southern fringes of New Delhi was abuzz with just one thing: The plague scare that had created quite a panic in the western and northern parts of India. JNU wasnt immune to the perceived threat of a looming epidemic and the university authorities declared a weeks holiday.

In the midst of all the chaos over whether one should leave the campus or stay put, one batchmate of mine at the School of Languages had a very innocuous query for one of the senior students in the School for Social Sciences: How serious is the plague threat? Pat came the reply I can only talk about the political angle of plague leaving the questioner befuddled.

My first brush with campus agitation was barely within a few days after I joined the university, when I saw a bunch of students skipping lunch to attend a demonstration outside the vice-chancellors office, demanding sufficient hostel rooms.

Later that day, as dinner was served at the mess in Narmada Hostel, where I was a resident, cyclostyled pamphlets being distributed among students caught my attention. A closer look revealed a charter of demands from a Left-leaning students outfit, asking the World Bank and United States to refrain from their pro-corporate and anti-proletarian policies towards the Third World.

Hyper-sensitive culture

In a nutshell, that has always been the JNU story. Scarcely will one come across an educational institution in India that is politically so active, aware and sensitive. And the best part of this hyper-sensitive political culture, so to speak, was the fact that every single voice, every single shred of opinion was allowed unfettered space and attention without fear or favour.

A JNU Students Union election was the best example of this inclusive atmosphere where two students JNUSU presidential candidates for two different students outfits propounding two opposing views in a fiercely fought presidential debate, would finally be seen having a good laugh at each other over steaming cups of tea and plates of bread-pakoda (a light snack) at the iconic Ganga Dhaba in the middle of the night.

And on the night the ballots were counted in multiple rooms on the first floor of the Administrative Block, or Ad Block in popular JNU parlance, groups of students from rival outfits would sit together in huddles in the courtyard and share their anxiety over cups of tea or coffee as the late-autumn night would progress.

There was political rivalry in JNU; there was a point-counterpoint contour to academics in JNU that went far beyond pedagogy; there was a clash of ideologies among a section of students in JNU the list is long. But there was never an eye-for-an-eye brand of nihilism among a section of JNUites as I presume exists today.

Never in my wildest dreams could I have imagined students and faculty being chased around by masked iron rod- and hockey stick-wielding goons. Never ever could I have imagined blood-soaked faces of members of rival student groups spewing venom at each other on social media.

Rival factions

One major reason why JNU managed to maintain a sense of decorum and sanity amid its super-charged political milieu is the fact that Left-leaning ideology always held sway over campus life in general and its political climate in particular. The rival factions would most often be aligned to Leftist thought, thereby acting as a foil to one another.

Battleground JNU was primarily dominated by either All India Students Association (Aisa) or Students Federation of India (SFI) the former affiliated with the ultra-Left Communist Party of India Liberation and the latter being the students wing of the Communist Party of India-Marxist. Akhil Bharatiya Vidyarathi Parishad, which owes its allegiance to the Bharatiya Janata Party (BJP), and National Students Union of India, the students wing of the Congress, were largely bit-players in this amphitheatre.

And SFI, in particular, with its moderate and more nuanced approach to socio-political issues, served as a perfect antidote to the Aisa brand of gung-ho scepticism, whereby, even the slightest hint of nihilism or anarchy would be nipped in the bud not through stick-wielding outsiders or militant insiders, but through a healthy practice of debate, discussion and a majority-endorsement of views and issues.

Us vs Them

With Aisa and SFI acting as a foil to one another, there was no us-vs-them dialectics on campus. Moreover, neither did the Central Government of the day really feel any serious need to get involved with campus politics, nor did the student outfits on campus ever allow any serious disruption of the academic pursuit in order to promote their agenda.

Since the BJP came to power at the Centre in 2014, two worrying trends have coalesced. Firstly, there has undoubtedly been an attempt to saffronise campus politics by forces outside JNU. Secondly, student politics within the campus has turned increasingly disruptive even to the extent of holding academics to ransom.

If masked goons wreaking havoc in JNU is a poor commentary on the political establishment trying to co-opt intellectual space and free speech, then students trying to disrupt the registration process for new admissions, in order to press with their demand for a rollback of higher fees, is no less worrying a sign of decadence.

Time has come for political forces within and outside the campus to answer this simple question: Do they really want the name JNU to be revered and sought-after; or do they want it to be just a relic of its past glory? That shouldnt be too hard a choice to make.

Middle Class Joe Biden has a corruption problem it makes him a weak candidate – The Guardian

Democrats are trying to choose a candidate to beat Donald Trump, the most corrupt president in history. Some think nominating Joe Biden, a moderate white man who calls himself Middle Class Joe, makes sense.

But Biden has a big corruption problem and it makes him a weak candidate. I know it seems crazy, but a lot of the voters we need independents and people who might stay home will look at Biden and Trump and say: Theyre all dirty.

It looks like Middle Class Joe has perfected the art of taking big contributions, then representing his corporate donors at the cost of middle- and working-class Americans. Converting campaign contributions into legislative favors and policy positions isnt being moderate. It is the kind of transactional politics Americans have come to loathe.

There are three clear examples.

First, Bidens support for finance over working-class Americans. His career was bankrolled by the credit card industry. He delivered for it by spearheading a bankruptcy bill that made it harder for Americans to reduce their debts and helped cause the financial crisis. He not only authored and voted for that bill, he split with Barack Obama and led the battle to vote down Democratic amendments.

His explanations for carrying water for the credit card industry have changed over time. They have never rung true.

Nominating a candidate like Biden will make it far more difficult to defeat Trump

The simplest explanation is the most likely: he did it for his donors. At a fundraiser last year, Biden promised his Wall Street donors that nothing would fundamentally change for them if he became president. Now the financial world is raising huge money for his campaign. It clearly thinks hes going to be its friend if elected. Most Americans, who get ripped off by the financial sector on a daily basis, arent looking for a candidate who has made their life harder.

Second, healthcare. On 25 April, the day he announced his campaign, Biden went straight to a fundraiser co-hosted by the chief executive of a major health insurance corporation. He refuses to sign a pledge to reject money from insurance and pharma execs and continues to raise money from healthcare industry donors. His campaign is being bankrolled by a super Pac run by healthcare lobbyists.

What did all these donors get? A healthcare proposal that preserves the power of the insurance industry and leaves 10 million Americans uninsured.

Third, climate change. Biden signed a pledge not to take money from the fossil fuel industry, then broke his promise. Right after a CNN town hall on climate change, he held a fundraiser hosted by the founder of a fossil fuel conglomerate. He is pushing climate policy that has gotten dismal reviews from several leading environmental groups.

There are plenty of other examples that raise questions, like housing and social security. Big real estate moguls are playing a major role in Bidens campaign. Unlike his rivals, he has no comprehensive housing plan. When he pushed for cuts to Social Security, was he serving donors or his constituents?

I can already hear the howls: But look at Trump! Trump is 1,000 times worse!

You dont need to convince me. I have spent my life writing about and fighting against corruption, and in America I have never seen anything like the current administration. In the last three years, I have made combatting Trumps corruption the heart of my work.

I was on the first lawsuit against him for corrupt constitutional violations and I ran for attorney general in New York on a platform of pointing out just how dangerous he is, and how important unused state laws are to stopping him. My work on corruption was cited in the House judiciary committees report on impeachment.

2020 should be about a crystal clear contrast between truth and lies, corruption and integrity, compassion and cruelty

But heres the thing: nominating a candidate like Biden will make it far more difficult to defeat Trump. It will allow Trump to muddy the water, to once again pretend he is the one draining the swamp, running against Washington culture. Trump and the Cambridge Analytica of 2020 will campaign, as they did in 2016, on a message of radical nihilism: everybody lies, everybody is corrupt, nothing matters, there is no truth.

Corrupt politicians always use whataboutism. With Biden, we are basically handing Trump a whataboutism playbook. The comparison wont be fair, but if you think he wont use Bidens closeness to donors as a cudgel to try to keep people home, you havent been paying attention. Unlike Democrats, who must give voters a reason to come out, Trump doesnt need voters to love him. He just needs to convince people the whole game is ugly.

Whether or not Biden is making choices to please donors, there is no doubt his record represents the transactional, grossly corrupt culture in Washington that long precedes Trump. We cannot allow Trump to so lower our standards that we arent even allowed to call out that culture, which has not only stymied progress but also harmed the Democratic party.

The good news is that we still have time to break with this culture of corruption. We dont have to choose Bidens way, which would give Trump a perfect foil. The 2020 election should be about a crystal clear contrast between truth and lies, corruption and integrity, compassion and cruelty.

We have a rare opportunity to end a larger culture of corruption and we should take it we will regret it if we dont.

The Districts have debuted a brand new track, ‘Cheap Regrets’ – Dork Magazine

It's the second single to arrive from their new record 'You Know I'm Not Going Anywhere'.

The Districts have debuted a brand new track.

Titled 'Cheap Regrets', it's the second single to arrive from their new record 'You Know I'm Not Going Anywhere', and follows up on last year's lead offering 'Hey Jo'.

Singer and guitarist Rob Grote explains: ""Cheap Regrets" is some late capitalist nihilism channeled into a Districts dance party. It's about the extremes of American culture constantly reinforcing the self. The mirror reconfirms you. It's all iPhone, selfies, and mirrors. Sell yourself baby. The consumer gets consumed. I wanted people to dance together to a song about alienation to find some collective transcendence in that."

'You Know I'm Not Going Anywhere' is set to be released on 13th March. You can check out 'Cheap Regrets' below.

Malami: Bring It On… Or Go To Blazes! By Bayo Oluwasanmi – SaharaReporters.com

All things considered, General Muhammadu Buharis regime is an anathema. General Buhari as President, continues to govern Nigeria as a nation where the lion is led by monkeys.

Buharis attorney general of the federation Abubakar Malami, is one of the most infamous members of Buharis cabinet. Malami always search for a banana peel to step on. When he cant find one to step on, he supplies his own. While we are yet to recover from his juvenile and primitive interpretation and application of court orders that granted Omoyele Sowore and Olawale Bakare bail, he came out like a confused lost cow and declared Amotekun illegal.

Amotekun is the security outfit established by the six governors of south west states to protect lives and properties of their citizens. Amotekun was conceived and birthed due to the abysmal failure of Buharis regime to secure life and properties of Nigerians. Political science 101 informs us that any government that fails to discharge the primary function of protecting life and properties of its citizens should cease to exist.

Only cowheads like Malami, Ibrahim Babangida and other backward feudal herdsmen terrorists need be reminded that as oxygen is to life, so also Amotekun is oxygen to Yoruba people for security. Malami, from time to time, believes administration of justice should be rationed selectively to different parts of the federation. He sees the application of justice as his prerogative to dispense to the ethnic group or groups he favours or the ones his northern terrorists recommend.

Malami is the worst unintelligent and professionally crude attorney general in modern Nigerian history. Malamis ethical and professional flagrant dishonesty in handling important national legal and constitutional issues that border on rule of law, equal justice, and the upholding of the constitution, shows how crooked the justice system has become under Buhari.

At every opportunity, Malami has managed to rewrite the constitution and redefine our laws: RUGA, court orders on bail, the supremacy of SSS, the illegal detention of Nigerians. The list goes on.

Malami has installed two systems of justice in the country - one for the south and another for the north with the north as superior to the south. As far as hes concerned, the north should be treated with special favour. Few examples will suffice: the security outfits of Hisbah and JTF in the north are legal and constitutional. Whereas Amotekun in the south is illegal and unconstitutional. Miyetti Allah is legal, but IPOB is a terrorist group.

Malamis ethical nihilism, his utter indifference to ordinary norms of professional behaviour, and his prostitution of justice, spell doom for the unity and co-existence of multi ethnic, multi culture, multi religion of different groups that make up Nigeria. Malami as the arrow head of northern feudal jihadists, is carrying out the larger agenda of the northern emirates: to suppress, oppress and subdue the south and Islamise Nigeria. This is why hes so concerned about the security and safety of northerners. But when it comes to the security of life and properties in the south, hes not affected. He could care less!

Malami has insufficient intelligence experience. As a lawyer and attorney general, he lacks the strong intelligence background to serve as attorney general. He does not represent the collective view of Nigerias intelligence community that believes in a fair, objective, and impartial one justice system for different ethnic groups in the country.

Justice security are key to a united Nigeria. Without justice and security, there can be no peace. Without peace, theres no Nigeria. Malami cannot sit in the comfort of his Abuja office and decree who has the right to live, who to wipe out, who Fulani herdsmen terrorists to kill or spare, where to deploy the police, which security agencies are legal or illegal. Yorubas will defend Amotekun with their last breath. No one can stop Amotekun. Amotekun is here and here for good and for life. Malami, bring it on... or go to blazes!

Jenee Halstead eyes the vacuum of the Internet age with ‘Disposable Love’ – Vanyaland

Sponsored by Studio 52. A community artist space located in the heart of Allston, and is proud to support the Boston music scene and local artist community.

Theres a certain freedom in acknowledging were all fragments of disposable data. Sure, weve all been slapped with an inevitable expiration date, but so has all human life since the dawn of time (and, come the information-harvesting, climate-crisis-ridden age of 2020, isnt it a relief that no one was built to last forever?) Call it cheerful nihilism, if you will.

Thats the exact lens though which Jenee Halstead chooses to view the world in her new tune Disposable Love, out today (January 17).

Disposable Love is an attempt to capture the hollowness and horror of the dark side of the digital/social media age, Halstead tells Vanyaland. Artificial Intelligence and big data serve as our new guiding principles and a compass for making sense of the world. This is a world that promises ease and accessibility, at the behest of turning over our valuable personal information. The dangers of a world driven by algorithm serves only to turn us further into consumers commodifying every human interaction and need as transaction.

Halsteads lyrics stalk her pop-rock noir melodies, eventually constricting the dampened heartbeat of this photoshopped hero wandering through the Internet age. Its morbid, yes, but its also revealing a kernel of truth.

Social media in particular plays off and takes advantage of our fundamental human needs: A desire for connection, to be informed and for recognition and relay with one another, Halstead adds. The companies behind these platforms manipulate our basest egoic nature seeking to profit off an environment steeped in voyeurism, comparison and competition. Digital devices further separate us into worlds of our of imagination, a hall of mirrors. Its lonely out there.

Fill some of the void with Halsteads new tune below, and catch her performing with Melissa Ferrick at The Burren for her single release party on Thursday (January 23).

Why string theory persists despite the knotty physics – Space.com

Paul M. Sutteris an astrophysicist at SUNY Stony Brook and the Flatiron Institute, host of Ask a Spaceman and Space Radio, and author of Your Place in the Universe.

String theory is a hypothetical idea that purports to be a theory of everything, able to explain the fundamental microscopic aspects of all of reality, from the forces of nature to the building blocks of all matter. It's a powerful idea, unfinished and untested, but one that has persisted for decades.

But the theory itself had rather inauspicious beginnings, employed to explain the strong nuclear force. And it wasn't very good at it.

Up until the 1960s, physicists were feeling pretty confident: They had discovered what they thought to be the fundamental constituents of matter (protons, neutrons and electrons). And they had recently accomplished the feat of unifying quantum mechanics and special relativity with what they called quantum electrodynamics (QED), which was a completely quantum description of the electromagnetic force.

But then, they started developing incredibly powerful particle colliders, and suddenly, they weren't really liking what they were finding. In these instruments, the physicists found a bunch of broken-up protons and neutrons, revealing that these particles were not fundamental at all. And what's worse, the colliders started spitting all sorts of new kinds of particles: mesons, pions, kaons, resonances, the works.

And governing them all was an apparently new force of nature: the strong force.

The tools used to develop QED were simply falling apart with this diverse host of particles popping out of the colliders. Physicists were at a loss and willing to try new ideas.

So some theorists started rummaging around in the attic, looking for any mathematical tools that might prove useful. And there they found an interesting set of ideas first proposed by Werner Heisenberg, one of the founders of quantum mechanics.

In the early days of quantum mechanics (the first half of the 20th century), it wasn't exactly clear what would be the best mathematical approach to explain all that weirdness. In the 1930s, Heisenberg suggested a rather extreme idea: instead of taking the normal classical physics approach of 1) write down the starting positions of all the particles involved in an interaction, 2) have a model of that interaction, and 3) follow the evolution through time of those particles, using your model to predict a result.

Instead, he argued, why don't we just skip all that work and develop a machine, called the scattering matrix, or s-matrix, that immediately jumps from the initial state to the final state, which is what we really want to measure. That machine encodes all the interaction in a giant box without actually worrying about the evolution of the system.

It was a cool idea but proved too difficult for anybody to get excited about, and it died on the vine until physicists got desperate in the '60s.

Reviving this approach to the newfound strong nuclear force, theorists extended and developed the s-matrix idea, finding that certain mathematical functions that repeated themselves were especially powerful.

Other theoretical physicists dived in, and couldn't resist the urge to give the framework a traditional interpretation in terms of time and space and following the evolution of particles. And there they found something surprising: in order to describe the strong force, it had to be carried by tiny, vibrating strings.

These strings appeared to be the basic building block of the strong force, with their quantum mechanical vibrations determining their properties in the microscopic world in other words, their vibrations made them look and act like tiny little particles.

In the end, this early version of string theory, known as baryonic string theory for the kinds of particles it tried to explain, didn't quite cut the mustard. It was fiendishly difficult to work with, making predictions nearly impossible. It also required the existence of particles that travel faster than the speed of light, called tachyons. That was a major problem for early string theory, since tachyons don't exist, and if they did they would flagrantly violate the incredibly successful special theory of relativity.

Oh, did I mention that baryonic string theory required 26 dimensions to make sense mathematically? That was a pretty big pill to swallow, considering that the universe has only four dimensions.

Ultimately, baryonic string theory died for two reasons. First, it made predictions that disagreed with experiments. That's a big no-no. And second, an alternative theory of the strong force, involving a new hypothetical particle called the quark and a force carrier called the gluon, was able to be folded into the quantum framework and successfully make predictions. This new theory, called quantum chromodynamics, or QCD, today remains our theory of the strong nuclear force.

And as for string theory, it mostly faded into the background. It would be revived in the 1970s, once theorists realized that it could describe more than the strong force and after they found a way to get rid of the tachyon predictions in the theory. The theory still needed extra dimensions, but physicists were able to reduce the number to a more reasonable-sounding 10. And with the realization that those dimensions could be tiny and curled up below the scale at which we could directly observe it, string theory didn't seem to wacky after all.

And today, that string theory also remains, still attempting to explain the strong force and so much more.

Nothingness Has Friction, And The Fastest Spinning Object Ever Made Could Measure It – ScienceAlert

Scientists have created the fastest spinning object ever made, taking them a big step closer to being able to measure the mysterious quantum forces at play inside 'nothingness'.

The record-breaking object in question is a tiny piece of silica, capable of whipping around billions of times per second - creating sufficient sensitivity that the team think they'll be able to use it to detect unfathomably small amounts of drag caused by the 'friction' within a vacuum.

Thescience of nothingnessis quickly becoming a big deal in physics, as we strive to understand how the Universe operates at its very foundations.

Researchers are now comfortable with the fact that empty space isn't empty at all - it's actually full of quantum fluctuations that we're only just now learning how to detect. But we're still struggling to find tools sensitive enough to measure these tiny forces at play.

Several years ago, researchers from Purdue University in the US took a step forward bydeveloping a method for measuring the torque or twisting force acting on a tiny oblong piece of diamond.

By using a laser to suspend the material in a vacuum, physicists had an incredibly finely-tuned device for working out the gentle nudge of surrounding fields.

"A change of the orientation of the nanodiamond caused the polarisation of the laser beam to twist," physicist Tongcang Li explained in 2016.

"Torsion balances have played historic roles in the development of modern physics. Now, an optically levitated ellipsoidal nanodiamond in a vacuum provides a new nanoscale torsion balance that will be many times more sensitive."

Three years later, Li and his team have replaced the diamond with tiny balls of silica just 150 nanometres in diameter, which were held aloft inside a vacuum chamber with a 500 milliwatt laser.

Using polarised pulses from a second laser, the tiny silica blobs could be set spinning.

And spin they did, with the dumbbell-shaped particles reaching an astonishing 300 billion rpm, breaking the limits on previous attempts which barely managed one fifth of that speed.

Revolutions aside, it was the sensitivity of the rotation's forces that the researchers were aiming to improve upon.

While this experiment relies on modern technology, it's has its roots in an experiment that's centuries old.

At the end of the 18th century, British scientist Henry Cavendish set out to put hard figures to Newton's laws on gravity by attempting to measure the force using two pairs of lead weights.

Two relatively light lead spheres balanced on either end of a 1.8-metre-wide beam were hung from a wire near a second pair of heavy masses locked in place. A measure of the torsion on the wire provided the first real measure of a gravitational constant.

This new, nanosized version of Cavendish's experiment could be so sensitive, it could theoretically be used to measure the faint tugging of electromagnetic fields that creates a kind of friction in empty space, formed by the inherent uncertainty of quantum physics.

"A fast-rotating neutral nanoparticle can convert quantum and thermal vacuum fluctuations to radiation emission," the researchers write in their report.

"Because of this, the electromagnetic vacuum behaves like a complex fluid and will exert a frictional torque on a nanorotor."

Twisting force of torsion is measured in units called 'newton metres', where one newton metre is a newton of force applied to a point of leverage from one metre away.

An experiment in 2016 developed a method that could measure torque as sensitive as around 3 x 10^-24 newton metres, a process that required temperatures just a fraction of a degree above absolute zero.

Li and his team blitzed this previous record as well, comparing the way the silica blobs spun between laser cycles to come up with torque measurements of just 1.2 x 10^-27 Newton metres. At room temperature too, no less.

In the future, experiments varying the make-up of the spinning material as well as environmental factors such as temperature and objects in the vicinity, could be used to finallymeasure how undisturbed quantum fieldsbubble away at the lowest energies.

Focus: Detecting the Rotation of a Quantum Spin – Physics

January 17, 2020• Physics 13, 5

Researchers detected the effect of rotating a crystal on the spin of an embedded particle, a result that could lead to ultrasensitive rotation sensors.

A. Wood/Univ. of Melbourne

A. Wood/Univ. of Melbourne

A new experiment has demonstrated that rotating a quantum object affects its spin in a way that can be detected. Researchers whirled a crystal at 200,000 rpm and detected the effects on a single quantum spin within the crystal. The finding was theoretically expected, but it could lead to new techniques for sensing rotation at the nanometer scale.

Particles such as electrons and protons have fixed values of quantum spin, an intrinsic angular momentum that does not correspond to physical rotation of the particle as it does for classical objects. Place such a particle (a single spin) in a magnetic field, and its spin vector rotates, or precesses, around the direction of the field vector, rather like a gyroscope. The speed of precession depends on the magnetic-field strength. Many influences, such as the fields of neighboring atoms, can affect the field that the spin experiences and thus the precession speed. If the particle has spin 1/2, then in an upward-pointing magnetic field it has a lower-energy (spin-up) state and a higher-energy (spin-down) state. Electromagnetic radiation with the same frequency as the precession can excite transitions between these two states.

It has been known for some time that the physical rotation of quantum spins (say, as part of a crystal) can alter the rate at which they precess, and some researchers hope that this fact might lead to a device for ultrasensitive detection of rotation [1]. Previous experiments have shown the effect for a large collection of spins, but doing so with a single spin would provide the ultimate in miniaturization and high spatial resolution. How do you get a single spin to tell you that its rotating? asks Alexander Wood of the University of Melbourne in Australia. The challenge, he says, is to show unambiguously that it is the rotation, and not some other influence such as a stray magnetic field, that has produced the effect on precession. The team overcame this difficulty by developing a complicated experiment that shows the effect of rotation indirectly.

Wood and his colleagues looked at diamond-crystal defects called nitrogen vacancy centers (NVs): places in the lattice where a lone nitrogen atom has replaced a carbon atom immediately adjacent to a vacancy (missing atom). This replacement leaves an unpaired electron, and it interacts with other electrons to create what is effectivelyin the appropriate magnetic fieldsan isolated spin-1/2 particle. If the NVs are very sparse, each spin can be seen and studied individually.

The team attached a small slab of diamond containing NVs to a motor spinning at 200,000 rpm in an external magnetic field. They looked at one NV and applied a technique called optically detected spin-echo magnetic resonance. For each rotation cycle (lasting a fraction of a millisecond), the team placed the spin in a lower-energy state using a green light pulse and then hit the spin with three carefully-timed microwave pulses. Finally, at the end of each rotation cycle, they measured the fluorescence emitted, which signaled whether the spin had been excited to the higher-energy state.

The orientations of the microwaves field vectors (polarizations) with respect to the spin determined the probability of the spin being excited to the higher-energy level. Using a theory accounting for this effect, the precession of the spin in the applied and microwave fields, and other effects, the team predicted the change in fluorescence as they varied the microwave polarization angle. These predictions agreed with the experiments. It turned out that the effect of varying the microwave orientation provided a signature in the fluorescence that uniquely signaled the NVs rotation and could not be explained by other factors.

The current experiment is a proof-of-principle with limited sensitivity, Wood says, but in the future, similar measurements could be used to detect rotation with high precision. The low sensitivity results from the tiny sensor volume, essentially a single atom. But he says that this probe size could also be an advantage: a nanometer-sized diamond containing a single NV might act as a probe for sensing rotation of living cells or biological fluids.

Pauli Kehayias of Sandia National Laboratory in Albuquerque, New Mexico, says that some researchers are already trying to use diamond NVs as the basis for a gyroscope that detects slow rotation [24], for example in navigation. But he says that using individual spins could lead to fast-rotation sensors that work at the atomic scale. In addition, a single spin would avoid complications from the inhomogeneity that might exist in a group of many NVs.

This research is published in Physical Review Letters.

Are the aliens us? UFOs may be piloted by time-traveling humans, book argues – Space.com

Unidentified flying objects (UFOs) have captured the public's attention over the decades. As exoplanet detection is on the rise, why not consider that star-hopping visitors from afar might be buzzing through our friendly skies by taking an interstellar off-ramp to Earth?

On the other hand, could those piloting UFOs be us our future progeny that have mastered the landscape of time and space? Perhaps those reports of people coming into contact with strange beings represent our distant human descendants, returning from the future to study us in their own evolutionary past.

The idea of us being them has been advanced before. But a recent book, "Identified Flying Objects: A Multidisciplinary Scientific Approach to the UFO Phenomenon" (Masters Creative LLC, 2019), takes a fresh look at this prospect, offering some thought-provoking proposals.

Related: UFO Watch: 8 Times the Government Looked for Flying Saucers

The book was written by Michael Masters, a professor of biological anthropology at Montana Technological University in Butte. Masters thinks that given the accelerating pace of change in science, technology, and engineering it is likely that humans of the distant future could develop the knowledge and machinery necessary to return to the past.

The objective of the book, Masters said, is to spur a new and more informed discussion among believers and skeptics alike.

"I took a multidisciplinary approach in order to try and understand the oddities of this phenomenon," Masters told Space.com. "Our job as scientists is to be asking big questions and try to find answers to unknown questions. There's something going on here, and we should be having a conversation about this. We should be at the forefront of trying to find out what it is."

Dubbing these purported visitors "extratempestrials," Masters notes that close-encounter accounts typically describe UFO tenants as bipedal, hairless, human-like beings with large brains, large eyes, small noses and small mouths. Further, the creatures are often said to have the ability to communicate with us in our own languages and possess technology advanced beyond, but clearly built upon, today's technological prowess.

Masters believes that through a comprehensive analysis of consistent patterns of long-term biocultural change throughout human evolution as well as recent advances in our understanding of time and time travel we may begin to consider this future possibility in the context of a currently unexplained phenomenon.

"The book ties together those known aspects of our evolutionary history with what is still an unproven, unverified aspect of UFOs and aliens," he said.

But why not argue that ET is actually a traveler from across the vastness of space, from a distant planet? Wouldn't that be a simpler answer?

"I would argue it's the opposite," Masters responded. "We know we're here. We know humans exist. We know that we've had a long evolutionary history on this planet. And we know our technology is going to be more advanced in the future. I think the simplest explanation, innately, is that it is us. I'm just trying to offer what is likely the most parsimonious explanation."

As an anthropologist who has worked on and directed numerous archaeological digs in Africa, France and throughout the United States, Masters observes that it is easy to conceptualize just how much more could be learned about our own evolutionary history if we currently possessed the technology to visit past periods of time.

"The alleged abduction accounts are mostly scientific in nature. It's probably future anthropologists, historians, linguists that are coming back to get information in a way that we currently can't without access to that technology," Masters said.

"That said, I do think that some component of it is also tourism," he added. "Undoubtedly in the future, there are those that will pay a lot of money to have the opportunity to go back and observe their favorite period in history. Some of the most popular tourist sites are the pyramids of Giza and Machu Picchu in Peru old and prehistoric sites."

Masters calls his UFO research "an evolving project."

"There's certainly still missing pieces of the puzzle," he said. "There are aspects of time that we don't yet understand. Wanted is a theory of quantum gravity, and we can meld general relativity and quantum mechanics. I'm just trying to put forth the best model I can based on current scientific knowledge. Hopefully, over time, we can continue to build on this."

"Masters postulates that using a multidisciplinary scientific approach to the UFO phenomenon will be what it takes to solve this mystery once and for all, and I couldn't agree more," said Jan Harzan, executive director of the nonprofit Mutual UFO Network (MUFON).

"The premise that UFOs are us from the future is one of many possibilities that MUFON is exploring to explain the UFO phenomenon. All we know for sure is that we are not alone," Harzan added. "Now the question becomes, 'Who are they?' And Masters makes a great case for the time-traveler hypothesis."

But not everybody is on board with the idea, as you might imagine.

"There is nothing in this book to take seriously, as it depends on the belief that 'time travel' is not only possible, but real," said Robert Sheaffer, a noted UFO skeptic.

Supposedly our distant descendants have mastered time travel, Sheaffer said, and have traveled back in time to visit us. "So, according to Masters, you just spin something fast enough and it will begin to warp space, and even send stuff backwards in time. This is a highly dubious claim," he said.

Moreover, Sheaffer said that Masters tries to deduce aliens' evolutionary history from witness descriptions, "suggesting that he takes such accounts far too literally."

David Darling is a British astronomer and science writer who has authored books on a sweeping array of topics from gravity, Zen physics and astrobiology to teleportation and extraterrestrial life.

"I've often thought that if some UFOs are 'alien' craft, it's just as reasonable to suppose that they might be time machines from our own future than that they're spacecraft from other stars," Darling told Space.com. "The problem is the 'if.'

Darling said that, while some aerial phenomena have eluded easy identification, one of the least likely explanations, it seems to him, is that they're artificial and not of this world.

"Outside of the popular mythos of flying saucers and archetypal, big-brained aliens, there's precious little credible evidence that they exist," Darling said. "So, my issue with the book is not the ingenuity of its thesis, but the fact that there's really no need for such a thesis in the first place."

Larry Lemke, a retired NASA aerospace engineer with an interest in the UFO phenomenon, finds the prospect of time-travelling visitors from the future intriguing.

"The one thing that has become clear over the decades of sightings, if you believe the reports, is that these objects don't seem to be obeying the usual laws of aerodynamics and Newtonian mechanics," Lemke said, referring to the relationship, in the natural world, between force, mass and motion.

Toss in for good measure Einstein's theory of general relativity and its consequences, like wormholes and black holes, along with other exotic physics ideas such as the Alcubierre warp-drive bubble.

"There's a group of thinkers in the field of UFOs that point out that phenomena reported around some UFOs do, in fact, look exactly like general relativity effects," Lemke said. Missing time is a very common one."

Lemke said that the idea that somebody has figured out how to manipulate space-time, on a local scale with a low-energy approach, would explain a lot of things across the UFO phenomenon, including those baffling Tic-Tac-shaped objects recently reported by jet-fighter pilots and radar operators.

"No matter how much knowledge we have, how much we think we know, there's always some frontier beyond," he said. "And to understand that frontier is getting more and more esoteric."

‘How can we compete with Google?’: the battle to train quantum coders – The Guardian

There is a laboratory deep within University College London (UCL) that looks like a cross between a rebel base in Star Wars and a scene imagined by Jules Verne. Hidden within the miles of cables, blinking electronic equipment and screens is a gold-coloured contraption known as a dilution refrigerator. Its job is to chill the highly sensitive equipment needed to build a quantum computer to close to absolute zero, the coldest temperature in the known universe.

Standing around the refrigerator are students from Germany, Spain and China, who are studying to become members of an elite profession that has never existed before: quantum engineering. These scientists take the developments in quantum mechanics over the past century and turn them into revolutionary real-world applications in, for example, artificial intelligence, self-driving vehicles, cryptography and medicine.

The problem is that there is now what analysts call a quantum bottleneck. Owing to the fast growth of the industry, not enough quantum engineers are being trained in the UK or globally to meet expected demand. This skills shortage has been identified as a crucial challenge and will, if unaddressed, threaten Britains position as one of the worlds top centres for quantum technologies.

The lack of access to a pipeline of talent will pose an existential threat to our company, and others like it, says James Palles-Dimmock, commercial director of London- and Oxford-based startup Quantum Motion. You are not going to make a quantum computer with 1,000 average people you need 10 to 100 incredibly good people, and thatll be the case for everybody worldwide, so access to the best talent is going to define which companies succeed and which fail.

This doesnt just matter to niche companies; it affects everyone. If the UK is to remain at the leading edge of the world economy then it has to compete with the leading technological and scientific developments, warns Professor Paul Warburton, director of the CDT in Delivering Quantum Technologies. This is the only way we can maintain our standard of living.

This quantum bottleneck is only going to grow more acute. Data is scarce, but according to research by the Quantum Computing Report and the University of Wisconsin-Madison, on one day in June 2016 there were just 35 vacancies worldwide for commercial quantum companies advertised. By December, that figure had leapt to 283.

In the UK, Quantum Motion estimates that the industry will need another 150200 quantum engineers over the next 18 months. In contrast, Bristol Universitys centre for doctoral training produces about 10 qualified engineers each year.

In the recent past, quantum engineers would have studied for their PhDs in small groups inside much larger physics departments. Now there are interdisciplinary centres for doctoral training at UCL and Bristol University, where graduates in such subjects as maths, engineering and computer science, as well as physics, work together. As many of the students come with limited experience of quantum technologies, the first year of their four-year course is a compulsory introduction to the subject.

Rather than work with three or four people inside a large physics department its really great to be working with lots of people all on quantum, whether they are computer scientists or engineers. They have a high level of knowledge of the same problems, but a different way of thinking about them because of their different backgrounds, says Bristol student Naomi Solomons.

While Solomons is fortunate to study on an interdisciplinary course, these are few and far between in the UK. We are still overwhelmingly recruiting physicists, says Paul Warburton. We really need to massively increase the number of PhD students from outside the physics domain to really transform this sector.

The second problem, according to Warburton, is competition with the US. Anyone who graduates with a PhD in quantum technologies in this country is well sought after in the USA. The risk of lucrative US companies poaching UK talent is considerable. How can we compete with Google or D-Wave if it does get into an arms race? says Palles-Dimmock. They can chuck $300,000-$400,000 at people to make sure they have the engineers they want.

There are parallels with the fast growth of AI. In 2015, Ubers move to gut Carnegie Mellon Universitys world-leading robotics lab of nearly all its staff (about 50 in total) to help it build autonomous cars showed what can happen when a shortage of engineers causes a bottleneck.

Worryingly, Doug Finke, managing editor at Quantum Computing Report, has spotted a similar pattern emerging in the quantum industry today. The large expansion of quantum computing in the commercial space has encouraged a number of academics to leave academia and join a company, and this may create some shortages of professors to teach the next generation of students, he says.

More needs to be done to significantly increase the flow of engineers. One way is through diversity: Bristol has just held its first women in quantum event with a view to increasing its number of female students above the current 20%.

Another option is to create different levels of quantum engineers. A masters degree or a four-year dedicated undergraduate degree could be the way to mass-produce engineers because industry players often dont need a PhD-trained individual, says Turner. But I think you would be training more a kind of foot soldier than an industry leader.

One potential roadblock could be growing threats to the free movement of ideas and people. Nations seem to be starting to get a bit protective about what theyre doing, says Prof John Morton, founding director of Quantum Motion. [They] are often using concocted reasons of national security to justify retaining a commercial advantage for their own companies.

Warburton says he has especially seen this in the US. This reinforces the need for the UK to train its own quantum engineers. We cant rely on getting our technology from other nations. We need to have our own quantum technology capability.

World’s Fastest Spinning Object Created by Scientistsand It Rotates at 300 Billion RPM – Newsweek

Scientists have set a new record for the world's fastest spinning object by creating a tiny device which spins at a staggering 300 billion revolutions per minute.

To put that into perspective, the device spins about 500,000 times faster than a dentist's drill, according to the team from Purdue University who designed it.

"It's always exciting to set a world record," Tongcang Li, an assistant professor of physics and astronomy, and assistant professor of electrical and computer engineering at Purdue, said in a statement.

The object is an incredibly small silica nanoparticlewhich looks like two spheres joined together when viewed through an electron microscope.

To make it spin extremely fast, the scientists simply used the power of light. First, they levitated the object in a vacuum using a laser, and then used another laser to accelerate it, according to a study published in the journal Nature Nanotechnology.

This is possible because particles of lightknown as photonsexert a tiny but measurable force on any object it comes into contact with. This force is known is light radiation pressure and its millions of times weaker than gravity.

"In the 1600s Johannes Kepler saw that the tails of comets always pointed away from the sun because of radiation pressure," Li said. "We use the same thing, but with concentrated lasers, to levitate and rotate the nanoparticles."

In addition to being the world's fastest spinning object, the nanoparticle also serves as the most sensitive known torque detector, the scientists said. Torque is a measure of the force that causes an object to rotate around an axis.

In fact, the device is 600-700 times more sensitive than any other previous device that's capable of measuring torque. The Purdue team say this will enable them to measure and investigate special effects in quantum mechanicsthe bizarre physics of the very small.

In 2018, the team set the previous world record for the fastest spinning object with a similar device that could spin at 60 billion rotations per minutea fifth as fast as the latest device.

While light radiation pressure is an incredibly weak force, the idea is being used to test new methods of spacecraft propulsion. For example, last year, the Planetary Society, launched a spacecraft known as LightSail 2 which propels itself by harnessing the gentle push of photons from the sun, similarly to how conventional sails use the power of the wind to propel boats.

Light Powers Worlds Fastest-Spinning Object to 300 Billion Revolutions per Minute – SciTechDaily

Scientists at Purdue University have created the worlds fastest-spinning human-made object and the most sensitive torque detector by suspending a nanoparticle in a vacuum with a laser, and then using a second laser to test its torque sensitivity. Credit: Purdue University image/Jonghoon Ahn

Nanoparticle levitated by light rotates at 300 billion rpm

A dumbbell-shaped nanoparticle powered just by the force and torque of light has become the worlds fastest-spinning object.

Scientists at Purdue University created the object, which revolves at 300 billion revolutions per minute. Or, put another way, half a million times faster than a dentists drill.

In addition, the silica nanoparticle can serve as the worlds most sensitive torque detector, which researchers hope will be used to measure the friction created by quantum effects.

The research was published this week in Nature Nanotechnology.

The researchers levitated the object in a vacuum using light in the form of a laser, and then used a second laser with a polarizing plate to alternate the optical torque on the object in order to test its torque detection sensitivity.

Its always exciting to set a worlds record, said Tongcang Li, assistant professor of physics and astronomy, and assistant professor of electrical and computer engineering.

The fastest-spinning object ever created is a nano-scale rotor made from silica at Purdue University. This image of the rotor at rest was created using a scanning electron microscope. For scale, the yellow bar in the image is 200 nanometers. Credit: Purdue University photo/Jaehoon Bang

In 2018, Li and his colleagues had set the previous world record for the fastest-spinning object with a similar device that was one-fifth as fast.

Hearing that the nanoparticle is powered by light could lead one to mistakenly think that the particle contains some sort of solar-powered capability. In fact, light itself exerts a miniscule, but measurable, amount of force on nearly any object.

You may not be able to feel it physically (only emotionally perhaps), but the light from those fluorescent lights in your office is literally and constantly pressing down on you because of something known as light radiation pressure. Its a force millions of times weaker than the gravity on you, but it is still there. In space, light can even propel satellites using light sails.

In the 1600s Johannes Kepler saw that the tails of comets always pointed away from the sun because of radiation pressure, Li says. We use the same thing, but with concentrated lasers, to levitate and rotate the nanoparticles.

In addition to the new track record in terms of rotation speed, the nanoparticles can measure torque at levels 600700 times more sensitive than any device before.

Li says this nano-torque detector will be used to measure and investigate quantum effects such as vacuum friction.

Its theorized that even objects in a vacuum levitated by light experience some very minuscule level of drag caused by virtual photons, a quantum fluctuation in a vacuum that is limited by the uncertainty principle. The nano-torque detector could also be used to measure related effects, including the Casmir effect and nanoscale magnetism, which could eventually allow engineers to develop and control nanoelectronic devices.

Tesla is on a tear, with no end in sight. That means the naysayers’ case is in ruins. – Business Insider

At the risk of invoking a clich, I'll point out that Tesla isn't a company whose stock trades on fundamentals, but rather on a story.

Think about that. At a simple level, the fundamentals are facts, while the story is an illusion a suspension of disbelief. When I was in my 20s, I spent a lot of time on story, before I dropped out of a doctorate program in literature at NYU. Stories have plots, subplots, plot twists, complicated characters who do complicated things. Stories can turn on a dime: in the space of a page, comedy becomes tragedy. As an author, you want to take readers on a ride.

For years now, story has dominated the debate around Tesla. And some large-scale characters, ranging from CEO Elon Musk to big-name hedge-funders like Jim Chanos and David Einhorn, have populated the tale. Even the minor characters have been interesting, and the plotlines and plot twists have been endless.

But the truth is that this story something of an epic, really filled a vacuum. Established automakers such as Ford and General Motors, have less lively stories because their actual businesses are so ... busy. The fundamentals the business facts produce millions of vehicles every year.

Tesla has only recently joined that club: 2019's total sales were about 367,000, a notable move up from 2018's roughly 250,000. But just a couple of years back, the company barely sold 50,000.

Sorry, shorts. Markets Insider

The sprawling, obsessively detailed, constantly argued over Tesla story happened only because there wasn't enough production or sales to stop it. If Tesla had built a competent franchise dealer network in the US (or joined with an existing mega-dealer) rather than trying to sell vehicles direct to customers, and if Tesla had hired a seasoned contract manufacturer to build some vehicles and meet demands sooner, the story would have petered out in 2017 or 2018.

Didn't go that way, and thus we got an insane episode of Musk tweeting his way into an SEC investigation and eventual settlement, a pitched battle between the #TSLA fanboy and the #TSLAQ bankruptcy crowds, and a preoccupation with Tesla's inner-workings that resembled Cold War Kremlinology.

But look what's happened since Tesla's output of actual cars has picked up: the stock has been on a tear, blasting through $300 per share, $400 per share, and (remarkably) $500 per share in a matter of months. Tesla's market cap, at $90 billion, is nearly equal to GM's and Ford's combined.

This isn't a rally story. Tesla completely dominates the electric vehicle market and can now look forward to potential competitors having to spend, spend, and spend some more if they want to duke it out for market share. This is going to be painful because the traditional automakers won't have to break a sweat to build EVs, but they'll be forced to expend millions if not billions of dollars convincing consumers to buy them.

Tesla, meanwhile, isn't spending anything, and hasn't. That doesn't constitute a first-move advantage so much as an only-mover leg up. Electric cars were stupid risky in the past, but Tesla gobbled up that risk. Now, the reward.

Busting through three resistance levels on the stock in three months is mind-blowing. And there isn't necessarily anything on the horizon to slow Tesla down. It reports fourth-quarter and full-year 2019 earnings in late January, and they're expected to be positive. If Tesla meets or beats, look out above. The 100% return of the past three months could look like a tame precursor, as Tesla's substantial short interest is decisively flushed out of the action.

Tesla has some looming challenges. The biggest is that as it sells more Model 3 vehicles and soon, Model Y SUVs at lower price points to less well-heeled buyers, it's going to be highly stressed on the service front. Like any relatively new automaker, Tesla's vehicles lack ironclad reliability, so the company compensates consumers with a great warranty.

But without dealerships, Tesla doesn't have a solid built-in servicing model. Poor service means often means that owners who aren't living with fleets of vehicles at home fail to buy again from a manufacturer. Up to this juncture, Tesla has been selling to patient early adopters who probably own two or three cars; now that it's moving toward single-vehicle households, it could endure some pain.

That's merely the cost of doing business, however. With shares above $500, Tesla can now effortlessly make good on its convertible debt obligations and, should it want to, raise additional capital to bolster its balance sheet. I think that would be smart, and if Tesla goes for it in 2020, the approximately $5 billion that the company has in cash could swell to $10 billion, and Tesla could start to deleverage.

This leaves Tesla's naysayers, so previously dependent on a story, with not much to use to push the stock around. The facts are the facts, the fundamentals are the fundamentals, and if you think the market for EVs could grow in the US, Europe, and China, then Tesla stock looks cheap in a world were EVs now make up just 2% of global sales.

I'll use the analogy of a predicted snowstorm to depict the naysayers' plight. The weather report is uncertain: we could get a few inches, but we could also get a blizzard. The discussion is speculative: What would we do in the worst case, assuming that it probably won't happen?

But then, the blizzard comes. And you have no choice but to surrender and dig yourself out.

Federal agency looking into Tesla driver complaints of sudden unintended acceleration – CNBC

Tesla Model 3

A division of the U.S. Department of Transportation is looking into driver complaints that Tesla electric vehicles may suddenly accelerate on their own.

CNBC has learned that an independent investor, Brian Sparks, submitted a petition to the National Highway Traffic Safety Administration and its Office of Defects Investigations asking them to look into the drivers' claims.

The petition includes a collection of 127 complaints that were either submitted to the government by Tesla owners, or others filing on their behalf. These complaints, when tallied, allege that unintended acceleration of Tesla electric vehicles may have contributed to or caused 110 crashes and 52 injuries.

Sparks said he conducted primary research and submitted the petition, which CNBC obtained, because he was moved by the personal story of Jennifer Terry. Sparks is currently shorting Tesla stock, but has hedged his bets and been long shares of Tesla in the past.

Terry was driving a new 2019 Tesla Model 3 in the summer of 2019, she says, when the vehicle's systems apparently failed and the car accelerated suddenly. She regained control of the Model 3, but was badly shaken by the incident.

She told CNBC she notified Tesla and requested an immediate service appointment, but the company offered her an appointment that was several weeks out. Just one week later, while she was waiting to have the car evaluated, the same thing happened to her again. This time, what Terry describes as sudden unintended acceleration (SUA) led to a four-car crash that injured two people. In her driver complaint to NHTSA in July 2019, Terry also said that some airbags in her vehicle failed to deploy.

Terry said on Friday that, although she has requested data and a resolution from the company, Tesla has yet to provide any diagnosis regarding what happened within her vehicle.

Sparks told CNBC, "I briefly looked on the NHTSA website to see if other Tesla drivers experienced the same. I didn't expect to see such a large number of [sudden unintended acceleration] complaints, most with similar fact patterns. That's when I decided to dig in."

NHTSA said, in a notice about the petition, that the scope of these allegations are broad and could apply to 500,000 Tesla vehicles including Model 3, Model S and Model X sedans and SUVs, made from 2013 through 2019.

Once it evaluates the contents of the petition, NHTSA -- which has the power to mandate vehicle recalls, or recalls of components and other technology in vehicles -- will decide if it should open a formal probe. If it decides not to offer a formal probe, it is expected to say why not, with an entry on a federal registry. The NHTSA investigator assigned to evaluate the petition is Ajit Alkondon.

Historically, the Department of Transportation (and NHTSA) receives myriad complaints about possible unintended acceleration incidents in a wide number of vehicles.

Both evaluated Toyota and Lexus vehicles in the 2000s to determine if defects in their electrical systems led to sudden acceleration and crashes. Many incidents that drivers ascribe to unintended acceleration, upon investigation, are found to be caused by driver errors, like pedal misapplication.

Tesla vehicles include newer technologies, such as the company's signature advanced driver assistance system, Autopilot, and "Ludicrous mode" acceleration, which allows drivers of some Model 3 variants to go from 0 to 60 mph in less than 4 seconds.

Tesla's press and investor relations teams did not respond to a request for comment.

Tesla is now worth more than Ford and GMcombined – Ars Technica

Enlarge / Elon Musk celebrates the opening of a new Tesla factory in Shanghai, China.

Less than a month after Tesla's stock first rose above $400, the company's shares have now soared past $500 per share. As I write this, one share of Tesla stock is worth $516, which means the company as a whole is worth more than $93 billion.

The latest rally was sparked by a new report fromColin Rusch, an analyst at the Wall Street firm ofOppenheimer & Co. He revised his Tesla price target upward from $385 to $612. But more fundamentally, the rising stock price reflects the fact that, after a couple years of near-constant chaos, the company seems to finally be executing smoothly.

Tesla delivered 112,000 cars in the fourth quarter of 2019 and367,500 for the full year. Both were new records for the company; Tesla barely achieved its goal to deliver at least 360,000 cars for the year.

And the company is poised for continued growth. Tesla opened its new factory in China earlier this month, just a year after breaking ground on the new facility. The electric carmaker plans to build a third major car factory in Germany.

Tesla's rising stock price has put Elon Musk within striking distance of winning the first of 12 performance-based stock grants he negotiated in his 2018 compensation package. To win an award of 1 percent of the company's stockworth around $1 billionMusk must pass two milestones. First, Tesla stock must be worth more than $100 billionit's $93 billion now. Second, Tesla must hit specified targets for revenues and earningsfor example, $20 billion in annual revenue.

Tesla said in an October regulatory filing that the company has already hit this $20 billion revenue figure. That clears the way for Musk to collect his stock award if Tesla's share price rises above $553 in the coming months.

Tesla is now by far the most valuable car company in America. As I write this on Monday afternoon, Tesla's market capitalization is $93 billion, compared to $50 billion for General Motors and $37 billion for Ford. That's especially remarkable because GM sold around 20 times as many cars as Tesla in 2019, while Ford sold more than six times as many.

So what explains Tesla's astronomical stock price? You can never be sure what Wall Street is thinking, but two factors likely contribute to investor bullishness about Tesla.

One is growth. The global car market overall is pretty saturated, but many experts expect electric vehicles to be a growth market over the next decade. Governments around the world have created incentives for people to buy electric vehicles. Meanwhile, battery costs have been falling rapidly over the last decade and are expected to continue falling in the 2020s. That should mean falling electric car prices, which should expand the market for electric vehicles in the coming years.

And while most major carmakers are working on their own electric vehicles, Tesla's rivals have struggled to design vehicles that can capture the public imagination the way Tesla's cars do. The Model 3 was by far the most popular all-electric car in the United States in 2019, with substantial sales overseas as well. If Tesla can maintain its share of the electric vehicle market as the overall electric car market grows, Tesla could wind up being one of the world's leading automakers.

The other factor that could justify Tesla's high valuation is the potential for high margins.

Right now, Tesla is not an especially profitable company. But things could improve dramatically over time. Declining battery prices will improve Tesla's margins. As a young and inexperienced carmaker, Tesla may have greater room to improve the efficiency of its manufacturing.

At the same time, Tesla has something no other carmaker can match: a loyal, enthusiastic, and growing customer base.

I'm not the first person to compare Tesla to Apple, but I think the comparison makes sense. Apple only has 15 to 20 percent of the global smartphone market, well below Google's Android. But the distinctiveness of the iPhone platform combined with the loyalty of the Apple customer base means that Apple can charge a premium for the iPhone. As a result, Apple's share of smartphone industry profits is much larger than its share of unit shipments or revenue.

We don't know what the electric car marketplace will look like a decade from now. But it's not hard to imagine that marketplace evolving in a similar direction, with Tesla becoming the Apple of transportation. People will be willing to pay a few thousand dollars extra for the prestige and unique features of a Teslajust as they're willing to pay a few hundred extra dollars for an iPhone. And in the ruthlessly competitive car industry, even a small difference in price can translate into a big difference in profits.
