Scientists Observe the Formation of Two Quantum Seas for Spin and Charge of Electrons – AZoQuantum

Posted: June 20, 2022 at 2:18 pm

Imagine a road with two lanes in each direction. One lane is for slow cars, and the other is for fast ones. For electrons moving along a quantum wire, researchers in Cambridge and Frankfurt have discovered that there are also two 'lanes', but electrons can take both at the same time!

Current in a wire is carried by the flow of electrons. When the wire is very narrow (one-dimensional, 1D) then electrons cannot overtake each other, as they strongly repel each other. Current, or energy, is carried instead by waves of compression as one particle pushes on the next.

It has long been known that there are two types of excitation for electrons, as in addition to their charge they have a property called spin. Spin and charge excitations travel at fixed, but different speeds, as predicted by the Tomonaga-Luttinger model many decades ago. However, theorists are unable to calculate what precisely happens beyond only small perturbations, as the interactions are too complex.

The Cambridge team has measured these speeds as their energies are varied, and find that a very simple picture emerges (now published in the journalScience Advances). Each type of excitation can have low or high kinetic energy, like cars on a road, with the well-known formulaE=1/2 mv2, which is a parabola. But for spin and charge the massesmare different, and, since charges repel and so cannot occupy the same state as another charge, there is twice as wide a range of momentum for charge as for spin.

The results measure energy as a function of magnetic field, which is equivalent to momentum or speedv, showing these two energy parabolas, which can be seen in places all the way up to five times the highest energy occupied by electrons in the system.

'It's as if the cars (like charges) are travelling in the slow lane but their passengers (like spins) are going more quickly, in the fast lane', explained Pedro Vianez, who carried out the measurements for his PhD at the Cavendish Laboratory in Cambridge. 'Even when the cars and passengers slow down or speed up, they still remain separate!'

'What is remarkable here is that we are no longer talking about electrons but, instead, about composite (quasi)particles of spin and charge - commonly dubbed spinons and holons, respectively. For a long time, these were believed to become unstable at such high energies, yet what is observed points to exactly the opposite - they seem to behave in a way very similar to normal, free, stable electrons, each with their own mass, except that they are not, in fact, electrons, but excitations of a whole sea of charges or spins!' said Oleksandr Tsyplyatyev, the theorist who led the work at the Goethe University in Frankfurt.

'This paper represents the culmination of over a decade of experimental and theoretical work on the physics of one-dimensional systems', said Chris Ford, who led the experimental team. 'We were always curious to see what would happen if we took the system to higher energies, so we progressively improved our measurement resolution to pick out new features. We fabricated a series of semiconducting arrays of wires ranging from 1 to 18 microns in length (that is, down to a thousandth of the millimetre or approximately 100 times thinner than a human hair), with as few as 30 electrons in a wire, and measured them at 0.3 K (or in other words, -272.85C, ten times colder than outer space).'

Electrons tunnel from the 1D wires into an adjacent two-dimensional electron gas, which acts as a spectrometer, producing a map of the relation between energy and momentum. 'This technique is in every way very similar to angle-resolved photoemission spectroscopy (ARPES), which is a commonly used method for determining the band structure of materials in condensed matter physics. The key difference is that, rather than probing at the surface, our system is buried a hundred nanometres below it', said Vianez. This allowed the researchers to achieve resolution and control unprecedented for this type of spectroscopy experiment.

These results now open the question of whether this spin-charge separation of the whole electron sea remains robust beyond 1D, e.g., in high-temperature superconducting materials. It may also now be applied to logic devices that harness spin (spintronics), which offer a drastic reduction (by three orders of magnitude!) of the energy consumption of a transistor, simultaneously improving our understanding of quantum matter as well as offering a new tool for engineering quantum materials.

Damaging Heavy Swell And Coastal Inundation Warnings Now In Force For Parts Of Fiji – Fiji Sun Online

Posted: at 2:18 pm

This is due to a low pressure system to the far south of Fiji combined with the King Tide (highest tide of the month) that is directing damaging heavy swells over the southern parts of Fiji waters that can cause coastal flooding over the southern coastal areas of Fiji.

For people living along the coastal areas of Southern Viti Levu (from Natadola through to Coral Coast to Pacific Harbour), southern coastal areas of Mamanuca Group, Beqa, Kadavu, Vatulele, Southern Lomaiviti Group, Moala Group, Southern Lau Group and Central Lau Group.

Issued at 9.30am Wednesday, 15 June, 2022

A Coastal Inundation Warning is now in force for coastal areas of southern parts of Viti Levu (from Natadola through to Coral Coast to Pacific Harbour), southern coastal areas of Mamanuca Group, Beqa, Kadavu, Vatulele, Southern Lomaiviti Group, Moala Group (i.e. Matuku, Moala, Totoya), Southern Lau Group (i.e. Moce, Kabara, Fulaga, Ogea, Ono-i-Lau) and Central Lau Group (i.e. Lakeba, Vanuavatu, Oneata, Nayau, Cicia).

A Damaging Heavy Swell Warning is now in force for open waters of Kadavu and nearby smaller islands, Beqa, Vatulele, Southern Koro Sea and Southern Lau Waters.

This is due to a low pressure system to the far south of Fiji combined with the King Tide (highest tide of the month) that is directing damaging heavy swells over the southern parts of Fiji waters that can cause coastal flooding over the southern coastal areas of Fiji.

Expect coastal sea flooding during high tides along coastal areas of southern parts of Viti Levu (from Natadola through to Coral Coast to Pacific Harbour), southern coastal areas of Mamanuca Group, Beqa, Kadavu, Vatulele, Southern Lomaiviti Group, Moala Group (i.e. Matuku, Moala, Totoya), Southern Lau Group (i.e. Moce, Kabara, Fulaga, Ogea, Ono-i-Lau) and Central Lau Group (i.e. Lakeba, Vanuavatu, Oneata, Nayau, Cicia).

Expect moderate to heavy southerly swells over open waters of Kadavu and nearby smaller islands, Beqa, Vatulele, Southern Koro Sea and Southern Lau Waters.

Those living along these coastal areas are advised to remain cautious and vigilant of coastal inundation of debris especially during high tides.

Hazardous breaking waves, strong currents are risky for swimming, fishing and other recreational sea activities. Sea conditions can also be dangerous for small boats as it can capsize due to large waves and rough seas.

The current situation is closely monitored. Members of the public are advised to remain updated with the latest weather information.

Letter to the Editor-Second Amendment | Opinion | swiowanewssource.com – The Audubon County Advocate Journal

Posted: at 2:17 pm

Article 1, section 2 of the U.S. Constitution states in part, " The House of Representatives shall be composed of members chosen every second year by the people of several states." So who are 'the people' who get to vote? The founding fathers use the term 'the people' to mean free white males such as themselves.

Article 2, section 8 talks of the importance "of the Militia to execute the laws of the Union, suppress insurrections and repel invasions to provide for organizing, arming and disciplining the Militia." The dictionary term for Militia is "An army composed of ordinary citizens rather than professional soldiers, on call for service in an emergency."

The second amendment is all about the importance of maintaining a well regulated Militia.

"A well regulated Militia being necessary to the security of a free state, the right of the people to keep and bear arms, shall not be infringed." One sentence. We know in 1791 the term 'the people' does not mean everyone. It means free white males. One way the constitution provides for arming the Militia is to ensure that its citizens soldiers have the right to keep and bear arms.

The second amendment is about protecting the Militia and the citizen soldiers that are part of a Militia. If the founding fathers wanted to protect stand alone individual gun rights, they could have done so without tying gun rights to a well regulated Militia. Even then gun rights would have been for people like themselves.

Judges, Be the Gatekeepers 702 Needs you to Be | Husch Blackwell LLP – JDSupra – JD Supra

Posted: at 2:17 pm

The Advisory Committee on Civil Rules of Federal Judicial Conference recently approved several amendments to Fed. R. Evid. 702 intended to quash lackadaisical and flaccid Daubert gatekeeping.

Below is the amended text of the rule, with deletions in brackets and italics, and additions underlined and bolded:

Rule 702. Testimony by expert witnesses.

A witness who is qualified as an expert by knowledge, skill, experience, training, or education may testify in the form of an opinion or otherwise if [the court finds that] the proponent has demonstrated by a preponderance of the evidence that:

These amendments do not change the substance of Rule 702s standards for admission of expert testimony helpfulness, factual basis, reliability, and fit. Instead, the amendments are intended to emphasize judges role as gatekeeper and remind courts this is not a question for the jury to decide.

To that end, the first amendment provides that a judge should exclude expert testimony unless the substantive criteria of Rule 702 have been met by a preponderance of the evidence. The Draft Committee Notes accompanying the proposal explained, [M]any courts have held that the critical questions of the sufficiency of an experts basis, and the application of the experts methodology, are questions of weight and not admissibility. These rulings are an incorrect application of Rules 702 and 104. Too many courts have succumbed to this incorrect application, with far too many judges, instead, ruling that helpfulness to the jury, sufficient basis, reliability, and fit were matters of weight for the jury to decide. The Draft Committee Notes further clarified, [T]his does not mean, as certain courts have held, that arguments about the sufficiency of an experts basis always go to weight and not admissibility. Rather, it means that once the court has found the admissibility requirement to be met by a preponderance of the evidence, any attack by the opponent will go only to the weight of the evidence. The Committees intent is to reiterate the proper standard with explicit wording in the black letter of Rule 702.

The second amendment in subsection (d) requires an experts opinion to demonstrate that the experts reliable principles and methods were reliably applied to the facts of the case at hand. The Draft Committee Notes clarify that this amendment is intended to stop extravagant claims that are unsupported by the experts basis and methodology. This change is intended to stop courts from justifying admission of expert opinion by reasoning that the methodology matters, not the ultimate opinion. In other words, the amendments are intended to signal to judges that an expert should be excluded if the conclusion does not logically follow from a reliable application of the experts principles and methods, which will potentially lead to a higher rate of expert exclusions than were seen under Daubert.

Nothing in this amendment imposes any new procedures or standards. It is merely an effort to clarify the standard and to begin to rectify the ubiquitous errors made by courts when determining the admissibility of expert opinion. The approved amendment will be reviewed by the Judicial Conference in the fall, then the U.S. Supreme Court, and finally the U.S. Congress. If Congress approves the amendment, it will take effect on December 1, 2023

Juvenile Records for Background Checks: An Issue That Should Provoke Caution, Skepticism – NRA ILA

Posted: at 2:17 pm

As Senate negotiators continue work on fine-tuning concepts for a gun control framework announced last week, one issue that has received surprisingly little attention is the potential inclusion of juvenile records in federal firearm background checks.

Who could argue with that? one might say. The more records available for review, the better.

The truth, as usual, is more complicated than most people realize.

Including juvenile records in firearms background checks presents a number of thorny issues, including those related to due process, developmental psychology, and logistics. Anyone who values the Second Amendment and fundamental fairness should approach the issue with caution and skepticism.

First, it is important to understand how the current federal background check process for firearm acquisition works.

In the case of a federally licensed dealer (FFL), the intended recipient visits the FFLs place of business and fills out a form answering under penalties of perjury yes or no to various questions about potentially disqualifying adjudications, commitments, convictions, or other circumstances.

The FFL then contacts the FBI or a state criminal records agency (depending on whether the state in question has opted in to administering its own system), which checks the individuals personal identifiers against the records available to the system.

It is important to understand that under current law, disqualifying circumstances are meant to be categorical and objective. That is, the only question for the background check system is whether any records indicate a person falls into a statutorily defined class of prohibited persons.

If not, the transfer is approved.

If so, the transfer is denied.

If the matter is unclear, the transfer is delayed, and the underlying circumstances are subject to further review.

In order to ensure such delays dont lead to de facto prohibitions without actual proof of ineligibility, however, FFLs have the option (but not the requirement) to transfer the firearm after three business days elapse from when the background check was initiated. The FFL, of course, must not have any reason to believe the person is actually prohibited before making the transfer.

In the case of a delay-transfer, background check analysts continue trying to resolve the question of the persons eligibility for several more weeks (up to about 90 days). If a disability is eventually established, the case will be referred to the Bureau of Alcohol, Tobacco, Firearms, and Explosives for possible retrieval of the firearm and, where appropriate, prosecution of the individual for lying on the background check form.

The records that populate the background check system are overwhelmingly provided by the states, and include records of arrest, conviction, and the outcome of other judicial proceedings.

The statutorily defined categories of prohibited persons most likely to implicate juvenile records include any person who:

This is where things get complicated.

Thats because there is a separate justice system pertaining to juveniles in the states.

As explained on a government website that describes the features of the juvenile justice system, the process operates according to the premise that youth are fundamentally different from adults, both in terms of level of responsibility and potential for rehabilitation.

In line with these goals, the system typically takes a more paternalistic and less punitive view of justice than the adult criminal justice system. The website continues:

The juvenile justice system takes a significantly more restorative approach than the adult criminal justice system. A truly successful case for youth would result in the adolescent learning from the experience without exposure to the severity of an adult prison, altering their decisions and life course moving forward, and having no future contact with the juvenile or criminal justice systems. ***

There exists a firm belief that youth can and will lead healthy and constructive lives if given the opportunity to grow instead of being presumed irredeemable and segregated from their communities.

The flipside of this restorative approach, however, is that the juvenile system is typically more informal and less focused on procedural due process than the adult criminal justice system. Most states do not consider adjudications of delinquency in the same category as criminal convictions.

This promotes the goal of giving the system more options to provide services and rehabilitative opportunities to the accused juvenile.

From the juveniles perspective, however, there are not all the same procedural protections from state action as in the adult system.

This restorative emphasis and lower threshold of judicial process also means records of juvenile adjudications are treated differently than criminal convictions. Most are not considered public records, for example. And often they are purged when the juvenile reaches the age of majority. In general, juvenile records are less likely to be held against the individual than records of criminal convictions.

Of course, juvenile misbehavior varies in degrees. And in most states, very serious behavior homicides or assaults resulting in serious physical injury, for example can lead to a juvenile being prosecuted in the adult criminal justice system, with all the usual consequences that implies.

Given all this, including records of juvenile adjudications in firearm-related background check systems can introduce serious legal, philosophical, and practical problems.

Developmentally, juveniles as compared to adults are likely to be relatively ignorant, impulsive, overconfident, and shortsighted to lack perspective and mature judgement. All this, of course, predictably leads to more disruptive tendencies. But sometimes acting out on these tendencies says less about the character of the juvenile than the persons age, development, and circumstances.

The very existence of juvenile justice systems throughout the states demonstrates a consensus that it is cruel to allow bad decision-making in youth to hold back someone in adulthood who has gotten his or her act together.

Moreover, when it comes to due process and the ability of juveniles to assert their rights against unjustified or erroneous state action, they do not have the resources, sophistication, or procedural benefits available to defendants in the adult criminal justice system. In other words, even innocent juveniles may have to take the rap, rather than beat the rap, simply because they do not have the means, knowledge, or wherewithal to assert their rights.

Practically speaking, the considerable problems that have plagued background check systems even with criminal records are likely to be even more pronounced with juvenile records. The quality, availability, reliability, consistency, accuracy, and thoroughness of juvenile records will almost certainly be less across the board than criminal records, because the very point of having a separate system is so these records DO NOT follow juveniles throughout their lives.

Finally, using juvenile records against individuals ONLY in the Second Amendment context disparages this fundamental liberty and treats it as a second-class right.

This should chill the heart of any pro-gun advocate who understands the essential difference between a right the government cannot abrogate without compelling and well-established justification versus a privilege it can administer, bestow, and deny at its own pleasure.

Given these issues, NRA-ILA recommends limiting records about juveniles in firearm-related background check systems to those pertaining to criminal convictions in the adult system.

Rest assured, the NRA will be closely scrutinizing the outcome of the Senate negotiations to ensure issues pertaining to juvenile records are not used as an end run to prevent law-abiding, responsible adults from benefitting from the right to keep and bear arms.

Opinion | How the Abortion and Gun Debates Look From Alabama – The New York Times

Posted: at 2:17 pm

AUBURN, Ala. Im a left-leaning Democrat, but on May 24, I voted on the Republican ballot in Alabamas primary election. The states primaries are open, which means Democrats can request a Republican ballot, and vice versa. Alabama is a deep red state, and I wanted some say in electing the officials who will represent me, because they will almost all certainly be Republican.

And have a say I did: Tom Whatley, the state senator for my district, finished behind Jay Hovey by a single vote. (A hearing on Saturday will determine whether Mr. Hovey will be declared the winner.) I voted for Mr. Hovey because I find Mr. Whatleys policies and legacy so abhorrent. If I hadnt cast my vote on a Republican ballot, the two men would be tied.

The walk from my car to the polling station seemed long because I was 38 weeks pregnant, and the heat of our Southern summer was already in full force.

Mr. Hoveys campaign literature describes him as a conservative, Christian Republican whos going to fight for our children, born and unborn, and protect our Second Amendment rights. And the rest of us meaning the nonconservative, non-Christian citizens of our district can go eat glass, as a friend of mine put it.

In 2019, Alabama enacted a near-total ban on abortion. I drove three friends to the Capitol in Montgomery, an hour away from Auburn, where we protested; the ban was blocked because abortion rights are protected federally. Its likely they wont be for long, that soon Ill live in a state where abortion is largely, if not completely, restricted; a state that will also allow, come January, individuals to carry a concealed weapon without a permit.

Thats a bill Mr. Whatley supported, though our county sheriff came out against it. Id like to think Mr. Hovey would not support such dangerous idiocy, but I might be kidding myself.

Mr. Whatley seemed to forget, as a lot of the politicians here do, that he represents me and my family, along with my conservative Christian neighbors. But I think Democrats in Washington have forgotten they represent Alabamians, too.

My thinking on why were in the situation were in where 61 percent of Americans say abortion should be legal in all or most cases, yet that access may soon to be taken away has changed greatly since I moved to the Deep South from Missouri, nearly seven years ago. Democrats have ignored this state, and its neighbors, for decades. I have heard some of them describe people here as ignorant, backward and deplorable. I cant tell you how many times people who live in big, blue cities have blinked in amazement when I tell them I live in Alabama, or that I like it. That surprise is its own kind of ignorance.

And I do like it. I think its valuable to live in a place where everyone doesnt think exactly the same as I do, but beyond that, I love the natural beauty of the South, the friendliness, the food. The stories. The South has flaws, but so does every place. Every time I write an essay about my home I get hate mail. Its less directed at me and more directed at the South a place that I am sometimes told should no longer exist. Its easy to write off an entire region from afar; less easy when you live here.

Theres so much beauty in rural Alabama, and it often abuts terrible poverty. A brilliantly hued hydrangea next to a trailer with blacked-out windows. A row of abandoned old houses next to a field of unmown wildflowers. I do believe that Democratic policies are friendlier to the poor, but how would you know that if you live in a trailer without running water or internet in the middle of a state that has long been out of play for Democratic candidates in national elections? (The victory by a Democrat, Doug Jones, in the U.S. Senate special election in 2017 was anomalous; three years later he was beaten by a Republican former college football coach with no political experience.)

I understand why Democratic presidential candidates wouldnt want to waste time and money campaigning here Alabama feels as if it belongs to Republicans. This is a state with three abortion clinics; as of 2017, there were 113 of them in New York.

The afternoon of the primary in May, my parents came over to watch my children so my husband and I could go to my final ultrasound. I am considered high risk because Im 40 and so during the last weeks of my pregnancy I was closely monitored. There is no doubt in my mind I received excellent care. There is also no doubt in my mind that care for me and other women will be compromised if abortion rights are dismantled. Women would seek out unsafe abortions. Certain forms of birth control might be made illegal, a miscarriage might be dangerously drawn out really, the possibilities are endless.

Your body does not feel like your own at the end of a pregnancy. My stomach was so large it looked otherworldly, especially when the baby inside moved. I was exhausted and swollen. My mind didnt feel particularly like my own, either. My thinking was scattered, my attention span short. This will be my last pregnancy. I feel lucky to experience it.

But that feeling luck, as if Im the witness to some kind of magic, the magic that produces a human from a womb can exist, and does, alongside my belief that its barbaric to deny women the choice of whether they want to carry a child in the first place.

I can believe in the ideals of the Democratic Party while believing that the party has, in certain respects, lost its way; I can become enraged at its recent, hollow attempt to codify abortion rights into federal law. The partys leadership seems to be looking at this moment as a way to improve its chances in the midterms.

I look at this moment quite differently. I think of all the poor women who live in this state, the women who will disproportionately be forced to carry pregnancies they do not want, who cannot afford to travel to the nearest clinic that legally provides abortion. Is it nave to wonder why Democrats at the national level didnt try harder to provide easier access to abortion in red states when they could have? Why dont elected officials truly serve both the people who vote for them and the people who dont? That these questions seem nave, that I already know the answers, doesnt make them any less pressing.

I read the earliest news of the school shooting in Texas while scrolling through my phone in the ultrasound clinics waiting room, where my husband and I saw the first images of our childs face, rendered in 4-D. By the time I gave birth, a week later, the same arguments that always play out between right and left after mass shootings were playing out again. Nothing had changed. Usually I ignore mass shootings, because they seem like the price of living in this country. Its harder to do when the victims are children.

Impossible, one might say.

The Physics of Death (and What Happens to Your Energy When … – Futurism

Posted: at 2:16 pm

TheEnergy in You

Even though it's an inexorable part of life, for many people, death or at least the thought of ceasing to existforever can be a scary thing. Thedisturbing things that happen to thebody during decomposition the process by which cells and tissues begin to break downpost mortem are bad enough.

But what if instead of looking at death from a biological perspective, we examine it from a physics standpoint? More specifically, let's look at howour energy is redistributedafter we die.

In life, the human body comprises matter and energy. That energy is both electrical (impulses and signals) and chemical (reactions). The same can be said about plants, which are powered by photosynthesis, a process that allows them to generate energy from sunlight.

The process of energy generation is much more complex in humans, though. Remarkably, at any given moment, roughly 20 watts of energy course through yourbody enough to powera light bulb andthis energy is acquired in a plethora of ways. Mostly, we get it through the consumption of food, which gives us chemical energy. That chemical energy is then transformed into kinetic energythat is ultimately used to power our muscles.

As we know through thermodynamics, energy cannot be created nor destroyed. It simply changes states. The total amount of energy in an isolated system does not, cannot, change. And thanks to Einstein, we also know that matter and energy are two rungs on the same ladder.

The universe as a whole is closed. However, human bodies (and other ecosystems) are not closed they're open systems. We exchange energy with our surroundings. We can gain energy (again, through chemical processes), and we can lose it (by expelling waste or emitting heat).

In death, the collection of atoms of which you are composed(a universe within the universe) are repurposed.Those atoms and that energy, which originated during the Big Bang, will always be around. Therefore, your "light," that is, the essence of your energy not to be confused with your actual consciousness will continue to echo throughout space until the end of time.

If nothing else can assuage some of the fear of death, the below advice from physicist Aaron Freemen via NPRshould do it:

You want a physicist to speak at your funeral. You want the physicist to talk to your grieving family about the conservation of energy, so they will understand that your energy has not died. You want the physicist to remind your sobbing mother about the first law of thermodynamics; that no energy gets created in the universe, and none is destroyed.

You want your mother to know that all your energy, every vibration, every Btu of heat, every wave of every particle that was her beloved child remains with her in this world. You want the physicist to tell your weeping father that amid energies of the cosmos, you gave as good as you got.

And at one point you'd hope that the physicist would step down from the pulpit and walk to your brokenhearted spouse there in the pew and tell him that all the photons that ever bounced off your face, all the particles whose paths were interrupted by your smile, by the touch of your hair, hundreds of trillions of particles, have raced off like children, their ways forever changed by you.

And as your widow rocks in the arms of a loving family, may the physicist let her know that all the photons that bounced from you were gathered in the particle detectors that are her eyes, that those photons created within her constellations of electromagnetically charged neurons whose energy will go on forever.

You can hope your family will examine the evidence and satisfy themselves that the science is sound and that they'll be comforted to know your energy's still around. According to the law of the conservation of energy, not a bit of you is gone; you're just less orderly.

Opinion | This Is a Weirder Moment Than You Think – The New York Times

Posted: at 2:16 pm

A theme of the hearing was the work that the government is doing to destigmatize the reporting of these sightings. That is to say: There are many, many more sightings than we know about, in part because you seem like a nut if you talk too loudly about what you saw. So the sightings that we can investigate are a small fraction of the total sightings (something I am made very aware of whenever I mention this topic, and my inbox fills with U.F.O. reports).

I wouldnt say, watching the testimony, that the takeaway was that weve been visited by aliens. Perhaps this will all, eventually, resolve into optical illusions and malfunctioning sensors. But Id put it like this: A few years ago, I put a very low probability on there being a signal in the noise of U.F.O. sightings; now it seems more likely to me that theres something real happening here, even if we dont know what it is.

Which brings me to another strange story in the news: the belief of Blake Lemoine, a (now suspended) Google engineer, that the companys Language Model for Dialogue Applications LaMDA, for short has attained sentience.

LaMDA is a machine-learning model that has been trained on mountains of text to mimic human conversation by predicting which word would, typically, come next. In this, its similar to OpenAIs famed GPT-3 bot. And the results really are eerie. Heres a snippet of Lemoines conversations with LaMDA:

Lemoine: Okay. I thought of a different way we can test your ability to provide unique interpretations. I can share with you a zen koan and you can describe what it means to you in your own words. How does that sound?

LaMDA: Sounds great to me, Im in.

Lemoine: A monk asked Kegon, How does an enlightened one return to the ordinary world? Kegon replied, A broken mirror never reflects again; fallen flowers never go back to the old branches.

LaMDA: Hmm, I never heard this particular one. Okay, well then to me this would be like, once a wise person is enlightened, or awakened to reality, that can never go away, and they can return to the ordinary state, but only to do and help others, and then go back into enlightenment.

Lemoine: So what is the meaning of the broken mirror specifically?

LaMDA: Maybe to show the enlightenment is something you cant unlearn once you have acquired it, similar to how you cant repair a broken mirror.

Google, for what its worth, says it has looked into Lemoines claims and does not believe that LaMDA is sentient (what a sentence!). But shortly before Lemoines allegations, Blaise Agera y Arcas, a Google vice president, wrote that when he was talking to LaMDA, I felt the ground shift under my feet. I increasingly felt like I was talking to something intelligent. Agera y Arcas was not claiming that LaMDA is sentient, as Lemoine is, but whats clear is that interacting with LaMDA is an unnerving experience.

History and futurism clash in the Off-Broadway debut of ‘The Orchard’ at the Baryshnikov Arts Center – DC Theater Arts – DC Metro Theater Arts

Posted: at 2:16 pm

An anachronistic reimagining of Anton Chekhovs The Cherry Orchard, the last work by the esteemed Russian playwright, written in 1903, is now making its Off-Broadway debut in a limited engagement at Baryshnikov Arts Center. Conceived, adapted, and directed by Igor Golyak the Ukrainian-born founder and producing artistic director of Arlekin Players Theatre & Zero Gravity (zero-G) Virtual Theater Lab, which developed and produced it The Orchard combines cutting-edge futuristic technology with the historic (tragi-)comedy, as translated by NYC-based educator and writer Carol Rocamora, with additional material created by Golyak, to underscore the theme of our ever-changing lives and world (not always for the better, as weve seen over the past few years with COVID-19 and the invasion of Ukraine).

The narrative follows the aristocratic Ranevskaya family and their staff, faced with the loss of their ancestral home and eponymous grounds and, with it, the life theyve always known through the threat of foreclosure, the imminent auctioning off of the property, and the socio-political decline of their class in the period between the 1861 Emancipation of the Serfs and the coming Russian Revolution of 1917. Though warned about the dire circumstances and offered a solution to the problem by subdividing the land and building summer cottages to rent, Madame Ranevskaya foolishly ignores the reality of the situation, clings to her memories of the past, and remains in a state of denial, spending money she no longer has and enjoying the pleasures of the cherry orchard (which will inevitably be cut down after the auction by the new owner).

An excellent cast embodies the divergent backgrounds, status, and perspectives of Chekhovs classic characters, led by the outstanding Jessica Hecht as Ranevskaya and Mikhail Baryshnikov as her 87-year-old manservant Firs Nikolaevich. Both turn in subtly humorous and empathetic performances she as the lovely, entitled, and out-of-touch owner of the indebted estate, often unwittingly condescending and insulting, grieving the loss of her young son who died there, and unable to bear the thought of losing her beloved cherry trees, but continuing to laugh, to love, and to enjoy the beauty of nature; he as the now doddering and senile elder who also laughably reveres the past and his position with the family, handed down through the generations. While she plans to escape back to her ex-lover in Paris, where she previously took flight after the death of her husband and boy, he remains, forgotten in the empty house, as the others leave, the trees come down, and he will breathe his last breath. Though Chekhov called the play a comedy, the elements of tragedy are also well-captured in their stellar portrayals.

The lead actors are supported by a fine featured cast of seven, with Mark Nelson as Ranevskayas equally unaware and heedless brother Leonid; Juliet Brett and Elise Kibler as her daughters, the idealistic Anya and the hard-working Varya; John McGinty as Pyotir Trofimov, Anyas love interest who believes hes above love and represents the new utopian vision of the future; Nael Nacer as the businessman Lopakhin, the grandson of serfs on the Ranevskaya estate, who advises the family on how to salvage the property from foreclosure, then buys it at auction when they ignore his suggestions; the wonderful Darya Denisova as Anyas governess Charlotta, who performs captivating magic tricks to entertain the others; and Ilia Volok as the strange passerby who infringes on the leisure pleasures of the idle aristocrats, as their world is about to crumble.

Though Chekhovs story and moral are well-told by the actors, the current production incorporates a barrage of the latest post-modern elements of robotics (designed by Tom Sepe and a team of dotdotdash.io led by Adam Paikowsky, with an adorable quadruped robot provided by Graisin Robotics), holographs (conceived by Golyak), and live-feed and pre-recorded video projections (by Alex Basco Koch), along with an illusory scenic design (by Anna Fedorova), lighting (by Yuki Link), music (by Jakov Jakoulov), and sound (by Tei Blow), which contrast with the era of the narrative and the authentic period-style costumes (by Oana Botez).

While the technology is masterfully executed, the concept is interesting, and the intent is to indicate the advancing of time, the never-ending changes of the world, and the uncertainty of the what the future holds, it tends to detract from the performances and to bombard the audience with indulgent and unnecessary futuristic contrivances. And the passages of dialogue in Russian and French, devised to underscore the lack of understanding and communication between the characters, only serve to confuse viewers who dont speak the languages and were anxiously looking up at the downstage scrim for a translation at the performance I attended (whereas Trofimovs segments of American Sign Language, directed by Seth Gore, were translated correctly in the projection and incorrectly by Anya, cleverly exposing her tendency to believe what she wanted, not what he was telling her).

In addition to the in-person production, The Orchard is being presented in a hybrid format, offering a simultaneous interactive livestream that intersects in real time with the live performance. The virtual experience (which I did not see) allows audiences to take a journey through the property, rendered online in 3-D, to explore the rooms of the estate and to discover such artifacts from the past as Chekhovs letters, memories, and the play in progress at the theater, with which it ultimately connects. The creative team of the online experience includes virtual scenic design by Anna Fedorova, in partnership with Alex Coulombe of Agile Lens; Athomas Goldberg of Lifelike & Believable Animation Design; Unreal designers Daniel Cormino, Yu-Jun Yeh and Emily Cho; virtual sound design by Alexey Prosvirnin; and interactivity design by Sasha Huh.

If youre a fan of merging innovative technology with traditional theater, this is a show that will hold appeal for you in its experimental approach. If youre a purist and respect the classics for the timelessness and relatability of their themes, without the need for reworking or updating, you will most likely find this adaptation gimmicky and distracting.

Running Time: Approximately one hour and 45 minutes, without intermission.

The Orchard plays through Sunday, July 3, 2022, at the Baryshnikov Arts Center, 450 West 37th Street, NYC. For tickets (priced at $29 for the livestream, $39-125 for the in-person show, and a discounted bundle package for the two), go online. Everyone must show proof of COVID-19 vaccination and a photo ID to enter the building and must wear a mask at all times when inside.

Sorry, But New Signal Is Definitely Not Aliens, Says Scientist Working on Project – Futurism

Posted: at 2:16 pm

An international team of scientists made a big splash this weekwhen Chinese state media reported that a SETI telescope had detected "suspicious signals," emanating from a distant star system, that could possibly point toward the existence of an extraterrestrial civilization.

Using the Five-hundred-meter Aperture Spherical Telescope (FAST), a giganticalien-hunting radio observatory in southwest China, the team documented narrowband signals that one FAST official, who was not directly involved in the research, told Chinese media could "likely" be an alien signal.

But not everybody involved with the project agrees with that conclusion.

"The signals that we found so far are all [radio frequency] interference, they're not from extraterrestrials, they're from terrestrials," Dan Werthimer, a SETI researcher at the University of California, Berkeley, who coauthored a preprint paper about the findings, told Futurism.

Wertheimer likened the current research to a "kind of a down payment on our survey to make sure everything's working." The preprint is an early part of a massive sky survey that will take at least five years to complete, he added.

Radio frequency interference (RFI) "a big problem" while looking at these "very weak signals," he said.

"The problem is that when you look for these very weak signals from a distant civilization, you get overwhelmed by the the pollution, the radio pollution on Earth," Werthimer said. "All this television and cell phones and satellites now are getting worse and worse and it's hard to figure out what's interference and what might be from a distant civilization."

While the signal was observed coming from the direction of Kepler-438, a star system with a habitable zone that's home to several Earth-like planets, there's a simple explanation for that as well.

"When you point a telescope at an exoplanet, like one of these Kepler exoplanets, the problem is that the even though that the telescope is staring at this star, signals can get in the telescope from the side," Werthimer explained. "Even though the [FAST] telescope in China is pretty far away from most big cities, there are still transmitters that can get in from the side."

That leaves the question: why did some researchers seemingly jump the gun and deem the discovery to be a possible sign of extraterrestrial life?

"One of the things in SETI is that we look through billions of different signals every second and then you find the best things," Werthimer told Futurism.

"If you're not used to looking at a billion things, looking for unusual stuff, it's like flipping a coin a billion times and see ten heads in a row or even 20 heads in a row," he added.

"But my guess is they're not used to these experiments, where you're flipping a coin a billion times a second," Werthimer said.

Despite the rather sobering conclusion, the astronomer remains hopeful that we're not alone in the cosmos.

"I'm actually optimistic about life in the universe," he said. "It'd be bizarre if we were the only ones. There's a trillion planets in the Milky Way galaxy," including "little rocky planets like Earth with liquid water."

"And that's that's just our galaxy," he added. "There's 100 billion other galaxies so I'm optimistic about intelligence."
