Note: After presenting my research proposal and acceptance by my committee, I've been taking a well-needed break from blogging. I'll post on and off until the New Year, which isn't too far off. Happy holidays!

In recent years, evidence has emerged that quantum physics seems to play a role in some of life’s fundamental processes. But just how it might do this is something of a mystery.

On the one hand, quantum phenomena are generally so delicate that they can only be observed when all other influences are damped – in other words in carefully controlled systems at temperatures close to absolute zero. By contrast, the conditions for life are generally complex, warm, and damp. Understanding this seemingly contradictory state of affairs is an important goal.

So physicists and biologists are keen to explore the boundaries of these very different regimes—life and quantum mechanics—to better understand where they might overlap.

Now Rainer Dumke at the Nanyang Technological University in Singapore and colleagues have created an exotic quantum state called entanglement using a superconducting qubit and a microscopic animal called a tardigrade. Along the way, the team has created the most extreme form of suspended animation ever recorded. “The tardigrade itself is shown to be entangled with the remaining subsystems,” they say.

To perform their entanglement experiment, Dumke and co cooled their tardigrade to below 10 millikelvins, almost to absolute zero, while reducing the pressure to a millionth of that in the atmosphere. In these conditions, no chemical reaction can occur so the tardigrade’s metabolism must have entirely halted stopped and the processes of life halted.

“This is to date the most extreme exposure to low temperatures and pressures that a tardigrade has been recorded to survive, clearly demonstrating that the state of cryptobiosis ultimately involves a suspension of all metabolic processes given that all chemical reactions would be prohibited with all its constituent molecules cooled to their ground states,” say the researchers.

In this condition, the tardigrade can be thought of as a purely dielectric element. Indeed, the researchers simulated their experiment by treating the tardigrade as a dielectric cube.

The experimental setup consisted of two superconducting capacitors, which when cooled can exist in a superposition of states called a qubit. They placed the tardigrade between the capacitor plates of one qubit so that it became an integral part of the capacitor. The team was then able to measure the effect of the tardigrade on the qubit’s properties.

“We should do away with the absolutely specious notion that everybody has to earn a living. It is a fact today that one in ten thousand of us can make a technological breakthrough capable of supporting all the rest. The youth of today are absolutely right in recognizing this nonsense of earning a living. We keep inventing jobs because of this false idea that everybody has to be employed at some kind of drudgery because according to Malthusian Darwinian theory he must justify his right to exist. So we have inspectors of inspectors and people making instruments for inspectors to inspect inspectors. The true business of people should be to go back to school and think about whatever it was they were thinking about before somebody came along and told them they had to earn a living.”

What do borders do, mean, and look like in different parts of the world? How are they decided? Who or what might they protect? How might they do harm? How and why might they change?

Countries protect their borders for several reasons. This is especially true in areas where two or more countries have fought over the same land. Cambodia and Thailand are countries in Southeast Asia. They have disputed the territory of the Preah Vihear Temple for more than a century.

Sometimes, borders keep citizens from leaving a country. Nations like North Korea, Myanmar, and Cuba rarely allow their residents to cross their borders.

Many border disputes happen when people fight over natural resources. Natural resources are anything a person can use that comes from the natural environment. The countries of Sudan and Egypt have argued for years over a region called Hala'ib. Hala'ib is rich in the mineral manganese, a natural resource. Manganese is important for making iron and steel.

Border problems often come up when people from other regions take over an area and create borders. During the 1800s and 1900s, European countries colonized much of Africa. In other words, outsiders from Europe moved into Africa. They took control of the people there. They took the land as their own. European colonists created the borders of most African countries. However, the borders they made often did not always consider the different groups living in an area.

Excerpts from "Overview: What Are Borders?" Facing History

The Corporation is a 2003 Canadian documentary film written by University of British Columbia law professor Joel Bakan, and directed by Mark Achbar and Jennifer Abbott. The documentary examines the modern-day corporation. Bakan wrote the book, The Corporation: The Pathological Pursuit of Profit and Power, during the filming of the documentary.

A sequel film, The New Corporation: The Unfortunately Necessary Sequel, was released in 2020.

The documentary shows the development of the contemporary business corporation, from a legal entity that originated as a government-chartered institution meant to affect specific public functions to the rise of the modern commercial institution entitled to most of the legal rights of a person. The documentary concentrates mostly upon corporations in North America, especially in the United States. One theme is its assessment of corporations as persons, as a result of an 1886 case in the Supreme Court of the United States in which a statement by Chief Justice Morrison Waite led to corporations as "persons" having the same rights as human beings, based on the Fourteenth Amendment to the United States Constitution.

In a Google Internet search on "the mythology of race," a book that's in my library is in the upper right-hand corner of my search page: "'The Myth of Race: The Troubling Persistence of an Unscientific Idea' is a book by anthropologist Robert Wald Sussman arguing that race is not, and never has been, a valid biological category in humans." As humans migrated out of Africa, they landed in places that didn't have the direct UV light of the equatorial sun. Lack of sunlight, eating or discovering foods native to their new lands, humans like any other animal adapted, and changed appearances with respect to their environments. In Europe, they didn't require Melanin, their hair straightened in the harsh arctic winters. Over time, all they saw was "them," and as long as everyone looked the same, the only thing that spurred conflict was covetousness: property, livestock, attractive lovers, and wives. Once trinkets, bobbles, and currency replaced barter, that encouraged hoarding, and comparisons between neighbors: who has the most "stuff?" As men explored other parts of the globe and found "them" and their stuff, there had to be a justification for taking their stuff as their own, for "some" having most, and "others" having the least. We are at the tipping point in the struggle to maintain three legal fictions: borders, corporations, and racial categories.

• You are NOT in our borders: Mecca, 'Murica, "the promised land," the European Union, Wakanda forever. We are "us," and you are "them": you do not count, you are un-people.
• No Mitt Romney, "corporations are not people." The robber barons used a boondoggle of the 14th Amendment to confer to themselves and their progeny unlimited power. People have lifespans: corporations are practically immortal psychopaths.
• Until we find evidence of intelligent Martians, there is only ONE race, the human race.

Ubuntu (Zulu pronunciation: [ùɓúntʼù]) is a Nguni Bantu term meaning "humanity". It is sometimes translated as "I am because we are" (also "I am because you are"), or "humanity towards others" (in Zulu, umuntu ngumuntu ngabantu). Wikipedia

The aforementioned legal fictions are stifling our development as a species, but enriching the fat pockets of toxic, pathological families that consider themselves royalty, and worthy of worship (and have personality cults to do just that). At our current juncture, world government - genuine cooperation - is laughable. The conned danger of "others" makes us reinforce our borders, erect our walls, intern refugees in Libya, violating human rights with impunity. If there are any vaccines, the so-called First World Nations will receive the jabs first. Our performance during a pandemic has been pitiful. COP26 was whiter than the Oscars due to southern hemisphere nations (i.e., brown people) didn't receive the mRNA vaccines to ARGUE [about] that northern hemisphere nations (i.e., white folks) received first. So for safety reasons, browner nations were placed in political Zoom purgatory as the climate change can is kicked down the road.

The feckless mismanagement of Chief Justice John Roberts over his five radical brethren practically sealed the fate of the former Supreme Court: irrelevance. "Stare decisis is Latin for 'to stand by things decided.' In short, it is the doctrine of precedent. Courts cite stare decisis when an issue has been previously brought to the court and a ruling has already been issued. … Horizontal stare decisis refers to a court adhering to its own precedent" Cornel Law. If Roe v. Wade is overturned, there is no such thing as precedent. Expect same-sex marriage to fall next. After that, voting rights for African Americans, then all women's rights RBG fought for. Avalanches begin with a single snowflake. On the calendar, we barrel to the future; legally we'd be pre-Brown.

Oh, and the "gang of Putin" is chomping at the bit for another government shutdown, because Saint Ronnie saying "government is the problem" started a party grift that hasn't abated in 41 years, managing to "trickle-down" zero dividends, but trickle-up tax cuts without fail. They'd rather do important things like reading Dr. Suess in the well of the Senate or having Twitter battles with Big Bird.

Fear of the Antichrist - a malevolent narcissistic psychopath in a man suit - and the bloodlust for Armageddon fuels our current lunacy. It will not be benevolent aliens, a United Federation of Planets, superluminal space drives, or Heisenberg-defying matter re-sequencers that will spur the elimination of class struggle (and money, apparently). It will be global cooperation heretofore unseen.

"I am because we are." "I am because you are."

Such a world revolves around Ubuntu. We sadly seem bereft of its precepts.

Since it begins with "u" it must be associated with utopia: "nowhere place."

Visual Abstract

Topics: Biology, Biotechnology, COVID-19, Research

To advance a novel concept of debulking virus in the oral cavity, the primary site of viral replication, virus-trapping proteins CTB-ACE2 were expressed in chloroplasts and clinical-grade plant material was developed to meet FDA requirements. Chewing gum (2 g) containing plant cells expressed CTB-ACE2 up to 17.2 mg ACE2/g dry weight (11.7% leaf protein), have physical characteristics and taste/flavor like conventional gums, and no protein was lost during gum compression. CTB-ACE2 gum efficiently (>95%) inhibited entry of lentivirus spike or VSV-spike pseudovirus into Vero/CHO cells when quantified by luciferase or red fluorescence. Incubation of CTB-ACE2 microparticles reduced SARS-CoV-2 virus count in COVID-19 swab/saliva samples by >95% when evaluated by microbubbles (femtomolar concentration) or qPCR, demonstrating both virus trapping and blocking of cellular entry. COVID-19 saliva samples showed low or undetectable ACE2 activity when compared with healthy individuals (2,582 versus 50,126 ΔRFU; 27 versus 225 enzyme units), confirming greater susceptibility of infected patients for viral entry. CTB-ACE2 activity was completely inhibited by pre-incubation with SARS-CoV-2 receptor-binding domain, offering an explanation for reduced saliva ACE2 activity among COVID-19 patients. Chewing gum with virus-trapping proteins offers a generally affordable strategy to protect patients from most oral virus re-infections through debulking or minimizing transmission to others.

KASULO, Democratic Republic of Congo — A man in a pinstripe suit with a red pocket square walked around the edge of a giant pit one April afternoon where hundreds of workers often toil in flip-flops, burrowing deep into the ground with shovels and pickaxes.

His polished leather shoes crunched on dust the miners had spilled from nylon bags stuffed with cobalt-laden rocks.

The man, Albert Yuma Mulimbi, is a longtime power broker in the Democratic Republic of Congo and chairman of a government agency that works with international mining companies to tap the nation’s copper and cobalt reserves, used in the fight against global warming.

Mr. Yuma’s professed goal is to turn Congo into a reliable supplier of cobalt, a critical metal in electric vehicles, and shed its anything-goes reputation for tolerating an underworld where children are put to work and unskilled and ill-equipped diggers of all ages get injured or killed.

“We have to reorganize the country and take control of the mining sector,” said Mr. Yuma, who had pulled up to the Kasulo site in a fleet of SUVs carrying a high-level delegation to observe the challenges there.

But to many in Congo and the United States, Mr. Yuma himself is a problem. As chairman of Gécamines, Congo’s state-owned mining enterprise, he has been accused of helping to divert billions of dollars in revenues, according to confidential State Department legal filings reviewed by The New York Times and interviews with a dozen current and former officials in both countries.

California and the Biden administration are pushing incentives to make the United States a global leader in a market that’s beginning to boom: the production of lithium, the lightweight metal needed for the batteries of electric vehicles, and for the storage of renewable energy from power plants.

At the moment nearly all the lithium used in the United States must be imported from China and other nations. But that trend could shift within two years if an efficient method is found to remove lithium from power plant waste in California.

Since the 1970s, California has built power plants that make electricity from geothermal energy—steam from saltwater heated by magma from the molten core of the Earth. It now accounts for 6 percent of California’s power, but it is more expensive to produce than other forms of renewable energy, such as solar and wind power.

But that calculus could change if the wastewater from the process—a whitish, soup-like brine that contains a mixture of dissolved minerals and metals including lithium—can be separated so the lithium could be extracted.

According to a study by the Department of Energy, the Salton Sea in California’s Imperial Valley—one of two large geothermal energy production sites in the state—could produce as much as 600,000 tons of lithium annually.

Quantum materials known as Mott insulators can “learn” to respond to external stimuli in a way that mimics animal behavior, say researchers at Rutgers University in the US. The discovery of behaviors such as habituation and sensitization in these non-living systems could lead to new algorithms for artificial intelligence (AI).

Neuromorphic, or brain-inspired, computers aim to mimic the neural systems of living species at the physical level of neurons (brain nerve cells) and synapses (the connections between neurons). Each of the 100 billion neurons in the human brain, for example, receives electrical inputs from some of its neighbors and then “fires” an electrical output to others when the sum of the inputs exceeds a certain threshold. This process, also known as “spiking”, can be reproduced in nanoscale devices such as spintronic oscillators. As well as being potentially much faster and energy-efficient than conventional computers, devices based on these neuromorphic principles might be able to learn how to perform new tasks without being directly programmed to accomplish them.

There is a high price for willful ignorance.

The above is Dr. Carl Sagan, an Astrophysicist, five years fresh off of the success of the original Cosmos series. He’s speaking about mitigating the effects of greenhouse gases, what is now referred to as global warming in 1985. The administration was Reagan and Bush I in the first year of their lame duck, a little before the Iran-Contra scandal.

This address to Congress is thirty-six years before COP26, which because the rich European and wealthy nations have refused to pay climate reparations, we are whistling in the dark towards a climate tipping point that we will not be able to escape by penis rockets, virtual reality, or opiates.

The mitigation ideas he suggested weren’t that radical and could have been put in place before our current crisis of once-in-a-century storms on almost a monthly basis (take, for example, Washington State’s flooding). Each occurrence of “The Day After Tomorrow” is met with a collective, societal shrug as distractions are more alluring than impending disasters, unless it directly affects us, and interrupts our current video streaming, or Orwellian “reality TV.” We elected a narcissist in 2016 because WE are a nation of narcissists.

After a century of wielding extraordinary economic and political power, America’s petroleum giants face a reckoning for driving the greatest existential threat of our lifetimes.

An unprecedented wave of lawsuits, filed by cities and states across the US, aims to hold the oil and gas industry to account for the environmental devastation caused by fossil fuels – and cover up what they knew along the way.

Coastal cities struggling to keep rising sea levels at bay, midwestern states watching “mega-rains” destroy crops and homes, and fishing communities losing catches to warming waters, are now demanding the oil conglomerates pay damages and take urgent action to reduce further harm from burning fossil fuels.

Big oil and gas kept a dirty secret for decades. Now they may pay the price, Chris McGreal, The Guardian.

I read the print version of “O is for Oligarchy” in the Austin Chronicle in 2010. Prescient, as the consensus wouldn’t be reported in Business Insider (originally in The Telegraph by Zachary Davies Boren) until 2014. To be fair, Vox published a rebuttal to the oligarchy thesis two years later. Our collective experience belies the rebuke.

Our performance during this pandemic points to a system that is sluggish to the masses of people that funds its tax base, and lightning-fast for the 400 families in the US to get their needs met in whatever legislation they want to be pushed, and whatever new tax break they wish to receive. Critical thinking isn’t encouraged. Tribal “us, versus them” has been used to divide the masses since the founding of the republic, whether Native Americans, kidnapped Africans, women, LGBT, immigrants, genteel “wink-and-nod” racism cum “Critical Race Theory.” It is a con, passed down from father to scion, reinforced by exclusive gatherings at Bilderberg, the Bohemian Club, and Trilateral Commission. These were once the fodder of myth and conspiracy theories, but they actually have websites. I doubt if they’re discussing supporting the spread of democratic ideals across the globe. More likely, how to maintain the gaslighting of disdained "bewildered herds" of humanity and to continue to line their pockets.

They are, unfortunately, in an Ayn Rand-Atlas-Shrugged-Fountain-Head-Elysium of their own minds. A utopia of their zip codes, blithely unaware that as the poet John Donne stated, they are not gods, but “each is a piece of the continent, a part of the main.”

As Dr. Carl Sagan pointed out to a young Senator Al Gore in 1985, before he rendered his concerns in PowerPoint slides to Nobel laureate and an Oscar for the related documentary "An Inconvenient Truth," and the aptly-named "An Inconvenient Sequel: Truth to Power," pushing the problem off to future generations isn’t just intellectually lazy, it has in it a perverse and sadistic callousness. “Eat, drink, and be merry” now Epicurus, for indeed “tomorrow we may die.” However, tomorrow should not be one of the casualties in the pursuit of callous, temporal pleasures. For the lack of starships and despite exclusive cul de sacs, scions and serfs cohabit Terra Firma. I have ONE burning question:

How well can billions spend on a dystopian planet?

The amounts of heavy elements such as gold created when black holes merge with neutron stars have been calculated and compared with the amounts expected when pairs of neutron stars merge. The calculations were done by Hsin-Yu Chen and Salvatore Vitale at the Massachusetts Institute of Technology and Francois Foucart at the University of New Hampshire using advanced simulations and gravitational-wave observations made by the LIGO–Virgo collaboration. Their results suggest that merging pairs of neutron stars are likely to be responsible for more heavy elements in the universe than mergers of black holes with neutron stars.

Today, astrophysicists have an incomplete understanding of how elements heavier than iron are made. In this nucleosynthesis process, lighter nuclei must be able to capture neutrons from their surroundings. Astrophysicists believe this can happen in two ways, each producing about half of the heavy elements in the universe. These are the slow process (s-process) that occurs in large stars and the rapid process (r-process), which is believed to occur in extreme conditions such as the explosion of a star in a supernova. However, exactly where the r-process can take place is hotly debated.

One event that could support the r-process is the merger of a pair of neutron stars, which can result in a huge explosion called a kilonova. Indeed, such an event was seen by LIGO–Virgo in 2017, and simultaneous observations using light-based telescopes suggest that heavy elements were created in that event.

The short answer

We can measure time intervals — the duration between two events — most accurately with atomic clocks. These clocks produce electromagnetic radiation, such as microwaves, with a precise frequency that causes atoms in the clock to jump from one energy level to another. Cesium atoms make such quantum jumps by absorbing microwaves with a frequency of 9,192,631,770 cycles per second, which then defines the international scientific unit for time, the second.

The answer to how we measure time may seem obvious. We do so with clocks. However, when we say we’re measuring time, we are speaking loosely. Time has no physical properties to measure. What we are really measuring is time intervals, the duration separating two events.

Throughout history, people have recorded the passage of time in many ways, such as using sunrise and sunset and the phases of the moon. Clocks evolved from sundials and water wheels to more accurate pendulums and quartz crystals. Nowadays when we need to know the current time, we look at our wristwatch or the digital clock on our computer or phone. 

The digital clocks on our computers and phones get their time from atomic clocks, including the ones developed and operated by the National Institute of Standards and Technology (NIST).

SARS-CoV-2 appears to travel widely across the cerebral cortex

“Brain fog” is not a formal medical descriptor. But it aptly describes an inability to think clearly that can turn up in multiple sclerosis, cancer, or chronic fatigue. Recently, the condition has grabbed headlines because of reports that it afflicts those recovering from COVID-19.

COVID’s brain-related symptoms go beyond mere mental fuzziness. They range across a spectrum that encompasses headaches, anxiety, depression, hallucinations, and vivid dreams, not to mention well-known smell and taste anomalies. Strokes and seizures are also on the list. One study showed that more than 80 percent of COVID patients encountered neurological complications.

The mystery of how the virus enters and then inhabits the brain’s protected no-fly zone is under intensive investigation. At the 50th annual meeting of the Society for Neuroscience, or SFN (held in virtual form this month after a pandemic hiatus in 2020), a set of yet-to-be-published research reports chronicle aspects of the COVID-causing SARS-COV-2 virus’s full trek in the brain—from cell penetration to dispersion among brain regions, to disruption of neural functioning.

Abstract

Hall effect thrusters operating at power levels in excess of several hundreds of kilowatts have been identified as enabling technologies for applications such as lunar tugs, large satellite orbital transfer vehicles, and solar system exploration. These large thrusters introduce significant testing challenges due to the propellant flow rate exceeding the pumping speed available in most laboratories. Even with proposed upgrades in mind, the likelihood that multiple vacuum facilities will exist in the near future to allow long-duration testing of high-power Hall thrusters operating at power levels in excess of 100 kW remains extremely low. In this article, we numerically explore the feasibility of testing Hall thrusters in a quasi-steady mode defined by pulsing the mass flow rate between a nominal and a low value. Our simulations indicate that sub-second durations available before the chamber reaches critical pressure are sufficiently long to achieve the steady-state current and flow field distributions, allowing us to characterize thruster performance and the near plume region.

I. INTRODUCTION

Hall effect thrusters (HETs) are spacecraft electric propulsion (EP) devices routinely used for orbit raising, repositioning, and solar system exploration applications. To date, the highest power Hall thruster flown is the 4.5 kW BPT-4000 launched in 2010 aboard the Advanced EHF satellite¹ (which the HET helped to deliver to the correct orbit after a failure of the primary chemical booster), although a 13 kW system is being readied for near-term flight operation as part of the Lunar Gateway,² and thrusters at 50^3,4–100 kW^s power levels have been demonstrated in the laboratory. Solar cell advancements and a renewed interest in nuclear power have led the aerospace community to consider the use of Hall thrusters operating at even higher power levels. Multi-hundred kW EP systems would offer an economical solution for LEO to GEO orbit raising or for the deployment of an Earth-to-Moon delivery tug, and power levels in excess of 600 kW could be utilized for crewed transport to Mars.^5–9 While such power levels could be delivered using existing devices, a single large thruster requires less system mass and has a reduced footprint than a cluster of smaller devices.¹⁰

Amid the GOP's nationwide push against teaching about race and sexuality in schools, two members of the Spotsylvania County School Board in Virginia advocated for burning certain books, according to the Fredericksburg-based Free Lance-Star newspaper.

This came as the school board directed staff to begin removing "sexually explicit" books from library shelves, after voting 6-0 in favor of the removal, the Lance-Star reported. The board has plans to review how certain books or materials are defined as "objectionable," the paper said, which opens the door for other content to be removed.

Courtland representative Rabih Abuismail and Livingston representative Kirk Twigg both championed burning the books that have been removed.

"I think we should throw those books in a fire," Abuismail said. Meanwhile, Twigg said he wanted to "see the books before we burn them so we can identify within our community that we are eradicating this bad stuff."

November starts with the intensity of electoral politics. For other nations, the election cycle isn't "big business." The only similarity between The New York Times, and Newsmax is each follows a business model that relies on orchestrated anxiety and eyeballs. The "fourth estate" is yellow journalism now if it ever was something else noble.

Elections in other countries have weekends for early voting, and the event is a holiday in many places. The forces that don't want a "crisis of democracy" in the United States prefer to keep our current malaise at the slow speed of the status quo, and if possible, reverse time politically in defiance of the Second Law of Thermodynamics and time's arrow.

November should be the time to remove the October festival/Halloween decorations and begin to think of family gatherings (that we can do now that vaccination rates are going up), and the gentle pressure to advertise the Christmas/Hannukah/Solstice season on radio, television, and department store muzak.

A synagogue in Austin was set ablaze. "Antisemitic and racist stickers and flyers were found at Ramsey Park in central Austin Tuesday morning," according to KXAN.com. The antisemites were arrested for their crimes.

Election workers are getting death threats. This didn't have to happen. The model existed before 2016. Fascism is born of fear.

The conservative democrat survived an assassination attempt by Jared Lee Loughner, answering the call of the former Wasilla Mayor as if it came from Mount Sinai or Mount Olympus.

There is shouting at medical professionals, teachers in classrooms, and people wearing masks on planes, or in public places. For peace of mind, good people will not serve as election officials, seek public office, work in medicine, or education. Since "nature abhors a vacuum," we will see the rise of what used to be the mad quackery that John Boehner and Paul Ryan tolerated from Paul Gosar to "win." The quackery will become the center and the "Grand Old Party" is no longer the "Party of Lincoln," but a banana republic.

Terrorism (noun): the unlawful use of violence and intimidation, especially against civilians, in the pursuit of political aims.

"Kristallnacht, (German: “Crystal Night”), also called Night of Broken Glass or November Pogroms, was the night of November 9–10, 1938, when German Nazis attacked Jewish persons and property. The name Kristallnacht refers ironically to the litter of broken glass left in the streets after these pogroms. The violence continued during the day of November 10, and in some places, acts of violence continued for several more days."

It took eighty-three years to go from the pogroms of Europe to the Kristallnacht of America.

We are on the precipice of a dystopian apocalypse.

Figure 2. Maxwell’s demon is a hypothetical being that can observe individual molecules in a gas-filled box with a partition in the middle separating chambers A and B. If the demon sees a fast-moving gas molecule, it opens a trapdoor in the partition to let fast-moving molecules into chamber B while leaving slow-moving ones behind. Repeating that action would allow the buildup of a temperature difference between the two sides of the partition. A heat engine could use that temperature difference to perform work, which would contradict the second law of thermodynamics.

Thermodynamics is a strange theory. Although it is fundamental to our understanding of the world, it differs dramatically from other physical theories. For that reason, it has been termed the “village witch” of physics.¹ Some of the many oddities of thermodynamics are the bizarre philosophical implications of classical statistical mechanics. Well before relativity theory and quantum mechanics brought the paradoxes of modern physics into the public eye, Ludwig Boltzmann, James Clerk Maxwell, and other pioneers of statistical mechanics wrestled with several thought experiments, or demons, that threatened to undermine thermodynamics.

Despite valiant efforts, Maxwell and Boltzmann were unable to completely vanquish the demons besetting the village witch of physics—largely because they were limited to the classical perspective. Today, experimental and theoretical developments in quantum foundations have granted present-day researchers and philosophers greater insights into thermodynamics and statistical mechanics. They allow us to perform a “quantum exorcism” on the demons haunting thermodynamics and banish them once and for all.

Loschmidt’s demon and time reversibility

Boltzmann, a founder of statistical mechanics and thermodynamics, was fascinated by one of the latter field’s seeming paradoxes: How does the irreversible behavior demonstrated by a system reaching thermodynamic equilibrium, such as a cup of coffee cooling down or a gas spreading out, arise from the underlying time-reversible classical mechanics?2 That equilibrating behavior only happens in one direction of time: If you watch a video of a wine glass smashing, you know immediately whether the video was in rewind or not. In contrast, the underlying classical or quantum mechanics are time-reversible: If you were to see a video of lots of billiard balls colliding, you wouldn’t necessarily know whether the video was in rewind or not. Throughout his career, Boltzmann pursued a range of strategies to explain irreversible equilibrating behavior from the underlying reversible dynamics. Boltzmann’s friend Josef Loschmidt famously objected to those attempts. He argued that the underlying classical mechanics allow for the possibility that the momenta are reversed, which would lead to the gas retracing its steps and “anti-equilibrating” to the earlier, lower-entropy state. Boltzmann challenged Loschmidt to try to reverse the momenta, but Loschmidt was unable to do so. Nevertheless, we can envision a demon that could. After all, it is just a matter of practical impossibility—not physical impossibility—that we can’t reach into a box of gas and reverse each molecule’s trajectory.

Technological developments since Loschmidt’s death in 1895 have expanded the horizons of what is practically possible (see figure 1). Although it seemed impossible during his lifetime, Loschmidt’s vision of reversing the momenta was realized by Erwin Hahn in 1950 in the spin-echo experiment, in which atomic spins that have dephased and become disordered are taken back to their earlier state by an RF pulse. If it is practically possible to reverse the momenta, what does that imply about equilibration? Is Loschmidt’s demon triumphant?

Wearable pressure sensors are commonly used in medicine to track vital signs, and in robotics to help mechanical fingers handle delicate objects. Conventional soft capacitive pressure sensors only work at pressures below 3 kPa, however, meaning that something as simple as tight-fitting clothing can hinder their performance. A team of researchers at the University of Texas has now made a hybrid sensor that remains highly sensitive over a much wider range of pressures. The new device could find use in robotics and biomedicine.

The most common types of pressure sensors rely on piezoresistive, piezoelectric, capacitive, and/or optical mechanisms to operate. When such devices are compressed, their electrical resistance, voltage, capacitance, or light transmittance (respectively) changes in a well-characterized way that can be translated into a pressure reading.

The high sensitivity and long-term stability of capacitive pressure sensors make them one of the most popular types, and they are often incorporated into soft, flexible sensors that can be wrapped around curved surfaces. Such sensors are popular in fields such as prosthetics, robotics, and biometrics, where they are used to calibrate the strength of a robot’s grip, monitor pulse rates, and blood pressure, and measure footstep pressure. However, these different applications involve a relatively wide range of pressures: below 1 kPa for robotic electronic skin (e-skin) and pulse monitoring; between 1 and 10 kPa for manipulating objects; and more than 10 kPa for blood pressure and footstep pressure.

Title source: The Unbearable Lightness of Being, a 1984 novel by Milan Kundera.

The White House correspondent slot is a coveted perch in Washington, DC, media real estate. After landing an excellent job and a press pass, a select few of journalism’s crème de la crème get to march through the White House gates and mix it up with the president’s inner circle; they get the chance, to tell the truth to power at the highest level, or at least to sit in on White House briefings and go to the White House correspondents’ dinner.

Some news organizations have sent reporters to the White House gaggle who have endured fame for their journalistic rigor and iconic visual profiles. Others—like the right-wing television channel Newsmax—seem to have missed the reasonableness memo.

Emerald Robinson, Newsmax’s White House correspondent, was taken to task this week for spewing some of the wildest COVID-19 vaccine disinformation seen on planet Earth to her 437,000 followers on Twitter. Robinson could simply have claimed that highly tested, safe, and effective coronavirus vaccines contain microchips that the government uses to track people. That would have been nonsense, but not far removed from a standard anti-vaxxer line. But Robinson made a more bizarre claim: She implied that the vaccines contain something even more devilish than microchips. The devil himself.

“Dear Christians, the vaccines contain a bioluminescent marker called LUCIFERASE so that you can be tracked. Read the last book of the New Testament to see how this ends,” she wrote in a since-deleted tweet.

What the hell? Newsmax correspondent thinks Satan is in COVID-19 vaccines, Matt Field, Bureau of Atomic Scientists

News flash: Beelzebub is not in your Covid vaccine. I’ve had both shots of Moderna and the booster. I have not spontaneously combusted, levitated furniture, cursed people out in Latin, or regurgitated pea soup (see: Linda Blair, in "The Exorcist").

The propaganda outlet’s title is Orwellian: nothing about it is “news,” nor is it superlative compared to all others.

If you’re a certain age, you recall the news by anchors like Walter Cronkite, Peter Jennings, Dan Rather, and Mike Wallace (Chris Wallace’s father). We had three stations, and a UHF channel on good days. The local news preceded the national news on ABC, CBS, and NBC. You had no idea who these gentlemen voted for. There was no “theme” to the channels: it was the news. Local and national news took ONE HOUR, it wasn't on repeat or loop, there were no smartphones with alerts. There was a morning, an evening newspaper that filled out the rest of what you needed to make sense of the world (we were in a Cold War with Russia). After that hour, the sitcoms and dramas filled the evening and did what they were supposed to do: entertain. There was no merger, no invention of "infotainment." It was what you needed as a citizen to make decisions about managing the republic. Every citizen had the responsibility of governance. Democrats could win one election, Republicans the next. The sacred text of the republic was The Constitution, it was sacrosanct.

Notice, I’m referring to our founding documents in the past tense.

Originally published in 1985, Neil Postman’s groundbreaking polemic about the corrosive effects of television on our politics and public discourse has been hailed as a twenty-first-century book published in the twentieth century. Now, with television joined by more sophisticated electronic media—from the Internet to cell phones to DVDs—it has taken on even greater significance. Amusing Ourselves to Death is a prophetic look at what happens when politics, journalism, education, and even religion become subject to the demands of entertainment. It is also a blueprint for regaining control of our media so that they can serve our highest goals.

“A brilliant, powerful, and important book. This is an indictment that Postman has laid down and, so far as I can see, an irrefutable one.” –Jonathan Yardley, The Washington Post Book World

Amusing Ourselves to Death: Public Discourse in the Age of Showbusiness, Neil Postman

Another book by Neil Postman and Steve Powers: “How To Watch TV News.” A summary:

An important guide to understanding what you’re getting--and not getting--from TV news. Postman and Powers warn that anyone who relies exclusively on TV for knowledge of the world is making a serious mistake and suggest ways to intelligently evaluate TV news shows.

Add to that: Facebook, Snapchat, Tik Tok, Twitter, et al. The sage advice is to read actual books, reputable sources of news, and maybe a course on critical thinking, and civics.

Emerald Robinson knew exactly what she was doing and probably knew enough to delete the tweet after it was sent. It’s the same excuse Rush Limbaugh used for his bombastic rants that were mantra from Budda for ditto heads: “I'm just an entertainer.” By stoking the rage-against-the-brown-boogiemen machine, Fox Propaganda, News Min, and Dumb Bart have made huge profits on what is arguably “white grievance minstrelsy,” previously known as “angry white men.” Neilsen ratings are another harangue, and television has one mission: product sales. It can be meal prep, travel businesses, or erectile dysfunction. "Soap Operas" was the self-pejorative of what are now the few daytime dramas that are left.

The Kyle Rittenhouse murder trial and the trial of the three murderers of Ahmaud Aubrey, miles distant from each other have the distinction of having ONE African American on the jury for EACH trial: 11:1. I was surprised by the Walter Scott murder trial verdict. I was surprised by the George Floyd murder trial verdict. For Briona Taylor and Trayvon Martin, the outcomes weren’t surprises, just infuriating.

There is a callousness to our discourse, as Carl Sagan once said "a celebration of ignorance." There is a difference between true ignorance, willful ignorance, and gaslighting. Ignorance is from a lack of information, that can be remedied. Willful ignorance is when you're speaking to an expert, reading a sourced document, and you willingly choose to combat the information, verbally, or physically, because it causes cognitive dissonance. Gaslighting is the tactic of an abuser, to make you question your reality. Emerald Robinson was gaslighting her Twitter followers, knowing it would get out into the Zeitgeist and fuel vaccine hesitancy, the main factor extending the pandemic her president bungled horribly. Gaslighting is abusive, but when you no longer question or resist the torture, you're a participant. O'Brien broke the will of Winston Smith in Orwell's "1984," there are as many fingers as O'Brien says there are.

For example, the elections Tuesday were predictable: every off-year election in Virginia and New Jersey has elected governors from the opposing party in the White House. The news media pounces on it: "it's a referendum on the current administration" they say, "it's a wakeup call to Democrats" says Kevin McCarthy, who manages to look like a howler monkey in a suit. With the exception of New Jersey, where Phil Murphy held on by a thread, that paradigm has repeated historically. Yet for eyeballs and detergent sales, cue the handwringing and pontification. Nielsen ratings.

Emerald Robinson preys on the existential fears of "the end times" by evangelicals steeped in the folklore and having watched a recent clip from the "Left Behind" series. From Hal Lindsey to Tim LaHay, eschatology is a lucrative business, unless the Chicxulub meteor hits before your booking on Morning Joe. "Christ Returns by 1988: 101 Reasons Why" has obviously fallen out of favor. It was quite a sensation in 1982.

Emerald would have been the head of the spear if the Virginia Governor's Race went Terry 'McAuliffe's way. There was obviously no "voter fraud," just bungling by McAuliffe, and defaulting to the comfortable by the DNC. McAuliffe is "known," but the Democratic Party needs to acknowledge its future isn't appealing to a dwindling white majority, but to constituents that look like "The Squad." Pretending otherwise, or deferring to 80s-style Democratic Leadership Council orthodoxy is political suicide.

Ms. Robinson would have contributed to whipping their audience into a dangerous, armed frenzy. Death Santis has a voter integrity bureau patterned after the Ministry of Truth, to intimidate legitimate voters, more or less brown voters, from participating in the franchise. Any election Republicans win is by definition legitimate. Any elections Democrats lose, they concede gracefully. Any elections Democrats win in the future will be fraudulent, and "stolen." The "Big Lie" is the only thing wanted from the previous occupant of the Oval Office. What they want is the obfuscation as a cudgel. That kind of propaganda leads to armed violence, and a failed state, not Florida: America.

This is not democracy. It is the fractured foundation of a crumbling republic.

I'm not sure if American companies, "woke" or otherwise, will come to our rescue. As long as the Stock Market functions, as long as product ships to customers, the one percent has always been socially distant with mansions in exclusive zip codes, in other countries, penis spaceships to visit Elysium, the investors, and boards will largely ignore societal collapse. The only devils are the architects of the "Big Lie." The hell is our slide into authoritarian rule, "not with a bang, but a whimper" (TS Eliot, "The Hollow Men").
