Vladimir Putin is a reality daytrader. His invasion of Ukraine is a "special military operation," not a war, or more accurately, an ongoing war crime. Gaslighting eleven Russian time zones is as easy to him as flatulence. With the GRU and American social media, he can hack American minds with the wildest conspiracy theories almost at will. The ridiculous QAnon claptrap that democrats are "demon-spawned, blood-drinking pedophiles" sounds like a propaganda tactic from the Kremlin:

Putin befriended and supported European politicians who were willing to defend Russian interests. One was Gerhard Schroder, the retired German chancellor, who was in the employ of the Russian gas company Gazprom. A second was Milol Zeman, elected president of the Czech Republic in 2013 after a campaign partly financed by the Russian oil company Lukoil, and reelected in 2018 after an election financed by unknown sources. A third was Silvio Berlusconi, who shared vacations with Putin before and after leaving the office of Italian prime minister in 2011. In 2013, Berlusconi was convicted of tax fraud and banned from public office until 2019. Putin suggested that Berlusconi's true problem was the persecution of heterosexuals. "If he were gay, no one would ever lay a finger on him." Here Putin was enunciating a basic principle of his Eurasian civilization: when the subject is inequality, change it to sexuality. In 2018, Berlusconi began a political comeback.

"The Road to Unfreedom: Russia, Europe, America," by Timothy Snyder, page 100 (paperback), author of "On Tyranny."

Gallop shows the number of adults self-identifying as LGBT ticking up to 7.1% isn't evidence of lower testosterone any more than it is of mythical cooties. We've gone from "Will and Grace," the sitcom "Soap," Ellen DeGeneres, and Rachel Maddow on primetime television to legalizing same-sex marriage as a Constitutional Right. At least on the surface, we seem to be more tolerant. Math question: isn't 7.1% less than 92.9%?

Or, take nonexistent voter fraud. The Brennan Center "found incident rates between 0.0003 percent and 0.0025 percent." Red states are making laws over something more infinitesimal than pocket lint.

An election happened in 2020, and the Russian asset (emphasis on the first syllable), lost. He couldn't even admit the truth to his friend Piers Morgan, telling him "what if you're not real?" In typical duplicitous snowflake fashion, he stormed out when confronted with the truth: he lost. Did we give this ingrate the nuclear codes?

Vance: Some opposition to Obama ‘comes from the color of his skin’

Vance also previously advanced [a] defense of former President Barack Obama, a Democrat who was the country’s first Black president, and who was falsely labeled a Muslim and was the subject of the racist “birther” conspiracy. Vance said he admired Obama for his personal accomplishments, even though he disagreed with him politically.

J.D. Vance used to admonish Donald Trump’s ‘xenophobic’ appeals to voters. Until he decided to run for Senate. Clevland.com

The "Big Lie" as popularized by Timothy Snyder in "Bloodlands" and executed by Vance and the American "son of perdition" has become less of a loyalty test, and more of a chanted mantra, eerily similar to Orwell's "two minutes hate" ritual. Yet, part of being in a cult means you curate reality: you daytrade it to avoid pain and steamroll up Maslow's pyramid to self-actualized pleasure. "Freedom" isn't the freedom to say two plus two equals four, it's the ability to troll on Twitter without fact check, or the threat of banning. (That worked out really well on January 6th.) What is painful to admit must be a conspiracy, not the outcome of voter mobilization, or concerns about fascism. "Others" - women, people of color, LGBT, youth - who did not vote for their Gollum avatar are "unpersons," and therefore since they do not exist, their votes are by definition fraudulent. Dehumanization is the first stage before slaughter and genocide.

Actual voter fraud committed during the 2020 election was committed by the followers of Putin's asset's personality cult. History has no impact and facts do not matter. Karl Rove opined about "creating realities" and for Putin and Russophiles like Rand Paul, Ukraine doesn't exist because it never existed. Therefore, uncomfortable histories about "your tribe" in the formation of the US must be banned, and I'm sure eventually, burned.

“Who controls the past controls the future. Who controls the present controls the past.”

“The best books... are those that tell you what you know already.”

“If you want to keep a secret, you must also hide it from yourself."

"Oceania has always been at war with Eastasia. Since the beginning of your life, since the beginning of the Party, since the beginning of history, the war has continued without a break, always the same war."

-George Orwell, "1984"

Alternative facts. Big lies. Created realities. These things are not the basis for democracy, and two plus two is not five.

“Now I will tell you the answer to my question. It is this. The Party seeks power entirely for its own sake. We are not interested in the good of others; we are interested solely in power, pure power. What pure power means you will understand presently. We are different from the oligarchies of the past in that we know what we are doing. All the others, even those who resembled ourselves, were cowards and hypocrites. The German Nazis and the Russian Communists came very close to us in their methods, but they never had the courage to recognize their own motives. They pretended, perhaps they even believed, that they had seized power unwillingly and for a limited time, and that just around the corner there lay a paradise where human beings would be free and equal. We are not like that. We know that no one ever seizes power with the intention of relinquishing it. Power is not a means; it is an end. One does not establish a dictatorship in order to safeguard a revolution; one makes the revolution in order to establish the dictatorship. The object of persecution is persecution. The object of torture is torture. The object of power is power. Now you begin to understand me.”― George Orwell, 1984, all quotes in italics from Good Reads

Ukraine foils Russia-backed cyberattack on the power grid, The Statesman

Summary

This joint Cybersecurity Advisory (CSA)—coauthored by the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), and the Department of Energy (DOE)—provides information on multiple intrusion campaigns conducted by state-sponsored Russian cyber actors from 2011 to 2018 and targeted the U.S. and international Energy Sector organizations. CISA, the FBI, and DOE responded to these campaigns with appropriate action in and around the time that they occurred. CISA, the FBI, and DOE are sharing this information in order to highlight historical tactics, techniques, and procedures (TTPs) used by adversaries to target U.S. and international Energy Sector organizations.

On March 24, 2022, the U.S. Department of Justice unsealed indictments of three Russian Federal Security Service (FSB) officers and a Russian Federation Central Scientific Research Institute of Chemistry and Mechanics (TsNIIKhM) employee for their involvement in the following intrusion campaigns against the U.S. and international oil refineries, nuclear facilities, and energy companies.[1]

• Global Energy Sector Intrusion Campaign, 2011 to 2018: the FSB conducted a multi-stage campaign in which they gained remote access to U.S. and international Energy Sector networks, deployed ICS-focused malware, and collected and exfiltrated enterprise and ICS-related data. 
  • One of the indicted FSB officers was involved in campaign activity that involved deploying Havex malware to victim networks. 
  • The other two indicted FSB officers were involved in activity targeting U.S. Energy Sector networks from 2016 through 2018.
• Compromise of Middle East-based Energy Sector organization with TRITON Malware, 2017: Russian cyber actors with ties to the TsNIIKhM gained access to and leveraged TRITON (also known as HatMan) malware to manipulate a foreign oil refinery’s ICS controllers. TRITON was designed to specifically target Schneider Electric’s Triconex Tricon safety systems and is capable of disrupting those systems. Schneider Electric has issued a patch to mitigate the risk of the TRITON malware’s attack vector; however, network defenders should install the patch and remain vigilant against these threat actors’ TTPs.
  • The indicted TsNIIKhM cyber actor is charged with an attempt to access U.S.-protected computer networks and to cause damage to an energy facility.
  • The indicted TsNIIKhM cyber actor was a co-conspirator in the deployment of the TRITON malware in 2017.

Tactics, Techniques, and Procedures of Indicted State-Sponsored Russian Cyber Actors Targeting the Energy Sector, Cybersecurity & Infrastructure Security Agency (CISA)

So the warning by CISA has some connotations we should think about. Since Nexflix bailed on Russia, they could block streaming services and retaliate rather petty. Another is infrastructure such as public utilities. Yeah, getting your AC turned off when it's in the eighties outside sucks, but a hospital getting its power cut during an emergency operation, an episiotomy or sinus surgery can cost lives that otherwise wouldn't be affected. It would affect water and utilities, access to ATMs, and Wall Street trading. Any attack is a move of desperation, not "strength." Any rat trapped in a corner will strike back, even with its last breath. Sean Hannity tried to give Mango Mussolini a layup question that he couldn't answer: "is Putin evil?" After bodies stacked like Hurricane Katrina victims, a plethora of war crimes that would embarrass HITLER, he still can't form his puckered mouth, which strangely looks like an anus, to criticize his handler; he is still the lapdog of a KGB spymaster. I doubt it has anything to do with pee tapes: it's darker than that. He wants to BE Putin, he wants America to be Russia. He wants Jeff Bezos to bow to him on the floor of the New York Stock Exchange in parody to 2 Thessalonians 2:4. Here is a failed businessman, a serial bankruptcy artist, a short-fingered vulgarian whose college professor stated he was the "dumbest student he EVER had," using more colorful metaphors. He takes a gig as host of a reality show to pay just enough of his crumbling life expenses to keep up the facade, and never admitted to himself that whatever his father had, he never had, and never will have. A person like that constructs fantasies because reality, "real reality," is too harsh for malignant narcissists. "Great again" in a sick mind is a dystopian nightmare to the sane rest of us, unless you're QAnon while reading this.

I think of Edward Snowden at this time. He's probably a valuable asset to Vladimir Putin and the GRU, despite his rock star status in exposing corruption: he broke the law and fled the country before it could prosecute him. Funny how he ends up in Russia; funny how the malware the GRU started using in 2016 suddenly "sprang up" spontaneously. I'm surprised no one is discussing this as a possibility. If you look at the link that I've provided, he boasted a top salary of $200,000 working at the NSA, as he put it, as a "computer Guru," without the benefit of a college degree. His paint job and privilege greased the skids to his ascension in the intelligence community (an oxymoron if there ever was one) and his six-figure salary. One thinks of the idioms "blowback" and "chicken's coming home to roost" the second made famous first by Chaucer of The Canterberry Tales before Malcolm X used the idiom to comment on President Kennedy's demise.

As Ukraine goes further in the crapper for the Russian bear, and Putin gets desperate to pull off a "win" in time for the May 9th festivities (the Soviet victory over Nazi Germany in WWII), cyber warfare is his best option to damage, deter the West, and save "face" at home. Moscow's Flagship sunk: either from Ukrainian armaments, or Russian naval incompetence. Social media is making it difficult to blame the "special military operation" on ghost Nazis. Since American billionaires hide their money in the Caymans, and Russian oligarchs (tomato, to-MAH-toe) hide their grand theft in western countries, "nuking the joint" just because you're pissed at looking bad doesn't make financial sense. Neither does the use of chemical weapons because the optics of killing babies in a majority white country can't endear you to the crowd that thinks white people are being "replaced." Free trade after Ukraine is going to have a cost for Vladimir: it's not going to be free, and like Finland and Sweden considering NATO membership, he may have sparked a global "Green New Deal" revolution that mere logic, and the absolutely sane desire to save the planet couldn't. The veneer of invincibility so-called strongmen like to exude can't be as shiny as it was when W "looked into his eyes, and saw his soul." At least the 46th president called "malarky" on that google-eyed tyrant worship, proto the fascism the right is exhibiting daily.

CPAC stands for "conservative political action committee," and the action you would THINK they would like to be politically responsible for is the election of conservative lawmakers to enact a platform and state an agenda. As of 2020, there is none, except supporting the American Orange Fuhrer. CPAC is meeting in Hungary, home of authoritarian leader Viktor Orbán, who has packed the courts, squelched the news down to a cheerleading outlet, attacked the LGBT in his country (guilty of the crime of EXISTING), rigged elections to where he cannot lose, demonized minorities and added to that antisemitism. Just the kind of country American Conservatives cum fascists (prior to WWII, there was a German American Bund that openly supported Hitler and the Nazis) would love to form in the US.

The Growth and Opportunity Project stated things that the right has thus far refused to do: change, evolve, give up the "Southern Strategy," start sounding less racist and appeal to more minorities, and young people. In other words, a functional political party would have taken the 2012 election loss as a wake-up call to course-correct.

What we are currently experiencing isn't a functional party. The party went from GOP to INGSOC, from Mitt Romney to a Boy From Brazil that had a copy of Hitler's speeches on his nightstand, that he obviously read. What he leads is more a Congress of sociopaths, people fearful of the changes their hubris wouldn't let them make. The percentage of black republicans has dwindled steadily since the 2000 RNC convention, but the New York Times managed to cobble a few together to make a point that fascists somehow have "inroads" with the African American community after Associate-Designate Supreme Court Justice Ketanji Brown-Jackson survived what amounted to a Klan coven. Yeah: inroads.

If the DNC isn't making attack ads with the material the insurrection party gave during her marathon, disrespectful confirmation hearings, it amounts to bringing a butter knife to a bazooka fight. It is political malpractice. Batman doesn't negotiate with the Joker: he pummels him and sends him back to Arkham. He does it as many times as necessary.

Racists could care less about diversity, equity, and inclusion, and fascists ONLY care about their "superiority" and making sure the necks they stamp on never shift from their places. Put on your flack jackets and gear up for piles of manure dressed up as political discourse. Get ready for malware blackouts and excuses that this direct attack on our homeland is somehow "our fault" because a psychopath believed his yes men, and got out over his skis. Like Dumbo Gambino, we're finding out the "stable geniuses" are all flatulence and hype.

In the words of Star Trek (any version): "red alert. Shields up!"

A lone black hole gives off no light - but its gravity does distort the path of light traveling around it. Ute Kraus (background Milky Way panorama: Axel Mellinger), Institute of Physics, Universität Hildesheim

Topics: Astrophysics, Black Holes, Cosmology, Einstein, General Relativity

Each second, a brand new baby black hole is born somewhere in the cosmos as a massive star collapses under its own weight.

But black holes themselves are invisible. Historically, astronomers have only been able to detect these stellar-mass black holes when they are acting on a companion.

Now, a team of scientists has made the first-ever confirmed detection of a stellar-mass black hole that’s completely alone. The discovery opens up the possibility of finding even more — an exciting prospect, considering there should be around 100 million such “rogue” black holes drifting through our galaxy unseen.

Relying on the neighbors

Black holes are difficult to find because they don’t shine like stars. Anything with mass warps the fabric of space-time, and the greater the mass, the more extreme the warp. Black holes pack so much mass into such a tiny area that space folds back in on itself. That means that if anything, even light, gets too close, its path will always bend back toward the center of the black hole.

Astronomers have found a couple hundred of these ghostly goliaths indirectly, by seeing how they influence their surroundings. They’ve identified around 20 black holes of the small, stellar-mass variety in our galaxy by watching as stars are devoured by invisible companions. As the black hole pulls matter from its neighbor, the material forms a swirling, glowing accretion disk that signals the black hole’s presence.

From TNT to nitro-glycerine, nitrogen-rich compounds are known for packing an explosive punch. When these materials explode, bonds between atoms in the compounds are broken, which gives a chance for two nitrogen atoms to form very strong triple bonds with each other. This releases an enormous amount of chemical energy due to the high strength of the triple bond, which is almost six times stronger than its single-band counterpart. In fact, the strength of nitrogen-nitrogen triple bonds is one of the reasons that the stable nitrogen gas dominates Earth’s atmosphere.

This chemical property of nitrogen is encouraging scientists to develop new nitrogen-rich compounds for use as high-energy-density materials that can be used as explosives or propellants. Polymeric nitrogen exists in the form of chains and tubes of linked nitrogen atoms with a high number of single or double bonds that can break and form triple bonds, releasing a large amount of energy and no dangerous by-products.

Several types of these polymers have been made at high temperatures and pressures, but they have been notoriously difficult to stabilize under ambient conditions. However, the electrochemical pressure inside the confined walls of carbon nanotubes may be the key to realizing these structures under more practical conditions. In a paper, published in Chinese Physics Letters, a team of scientists led by Jian Sun at Nanjing University provides a theoretical map of the process and the resulting compounds.

Cars – and in particular racecars – might seem the villains in a world grappling with climate change. Racing Green: How Motorsport Science Can Change the World hopes to convince you of exactly the opposite, with science journalist Kit Chapman showing how motorsports not only pioneers new, planet-friendlier machines and materials, but saves lives on and off the track too.

The first part of Chapman’s argument tracks the historical development of cars and competition. His stories show how, from its start, racing has served as a research lab and proving ground for new technologies. The first organized motor races were competitions to encourage innovation, akin to today’s X-Prizes. In 1894 Le Petit Journal offered a purse for the first car to make it from Paris to Rouen, while later races emphasized pure speed or, like the legendary 24 Hours of Le Mans, endurance. Chapman provides a whirlwind tour through the development of the internal combustion engine-powered car and its damning limitations, including the copious greenhouse-gas emissions and the inability to ever achieve more than 50% thermal efficiency.

He then introduces us to new racing series like Formula E and Extreme E, which have changed electric cars “from an eccentric folly to the undisputed future of the automotive industry”. Chapman highlights the advantages of electric vehicles without glossing over their drawbacks: recycling challenges, the potential for difficult-to-extinguish fires resulting from thermal runaway, and ethical/sustainability issues surrounding the materials used. Throughout this section, he links motorsport advances with “real-life” applications. For example, the same flywheels that enabled Audi’s hybrid racecars to take all three podium spots at the 24 Hours of Le Mans in 2012 made London buses more energy efficient. Some connections are a little more tenuous than others, but they are uniformly fascinating.

Reducing carbon dioxide emissions and removing them from the atmosphere is critical to the global fight against climate change. Called decarbonization, it is one of the focal points in the nation’s strategy to ensure a bright future for our planet and all who live on it.

The U.S. Department of Energy’s (DOE) Argonne National Laboratory has been at the forefront of the quest to decarbonize the U.S. economy for decades.

Argonne scientists are developing new materials for batteries and researching energy-efficient transportation and sustainable fuels. They are expanding carbon-free energy sources like nuclear and renewable power. Argonne researchers are also exploring ways to capture carbon dioxide from the air and from industrial sources, use it to produce chemicals, or store it in the ground.

The ultimate goal? To reduce the greenhouse gases that trap heat in the atmosphere and warm the planet.

How can you tell if a material is a superconductor? Four classic signatures are illustrated here. Left to right: 1) It conducts electricity with no resistance when chilled below a certain temperature. 2) It expels magnetic fields, so a magnet placed on top of it will levitate. 3) Its heat capacity – the amount of heat needed to raise its temperature by a given amount – shows a distinctive anomaly as the material transitions to a superconducting state. 4) And at that same transition point, its electrons pair up and condense into a sort of electron soup that allows current to flow freely. Now experiments at SLAC and Stanford have captured this fourth signature in cuprates, which become superconducting at relatively high temperatures, and show that it occurs in two distinct steps and at very different temperatures. Knowing how that happens in fine detail suggests a new and very practical direction for research into these enigmatic materials. (Courtesy: Greg Stewart, SLAC National Accelerator Laboratory)

Researchers in the US report that they have observed the so-called “fourth signature” of superconducting phase transitions in materials known as cuprates. The result, obtained via photoemission spectroscopy of a cuprate called Bi2212, could shed fresh light on how these materials, which conduct electricity without resistance at temperatures of 77 K or higher, transition into the superconducting state.

The superconducting transition occurs when a material loses all resistance to an electrical current below a certain critical temperature T_c. At this temperature, bulk materials exhibit four characteristic “signatures” – electrical, magnetic, thermodynamic, and spectroscopic – indicating that transition has occurred. The electrical signature is the development of zero resistance. The magnetic signature is the onset of the Meissner effect – that is, the material expels magnetic fields. And the thermodynamic signature is that the material’s heat capacity (the amount of heat required to increase its temperature by a given value) displays a distinctive anomaly.

Yeine Arameri is a young girl from a far-off land within The Hundred Thousand Kingdoms that is thrust into political war between her two cousins simply because her mother was a former heir to the kingdom, who turned her back on the throne. What should have been her mother’s position-and problem-to deal with is now hers. Her cousins want to kill her because she exists and is therefore a threat to them and their right to be heir to the throne. If Yeine can survive the first 24 hours in her new home, she just might live long enough to be killed when it is actually time to give up her life. You just have to read this wild-ride fantasy to see what I mean.

In a land where billions of people live alongside everyday magic and gods, The Hundred Thousand Kingdoms by N.K. Jemisin is a breathtakingly fresh take on fantasies. The word-building is rich and seamless intertwined with magic, gods, technology and political intrigue. A gem of a read.

I would like to announce that I have a new short story on my website titled "The Black Cross".It’s a detective yarn set in San Diego in 1940, with the protagonist (left) being a private eye who is called on to recover a black stone cross from Central Africa that he believes has been stolen by Chinese-American gangsters. But little does he know the true origin or significance of the cross, or what his adversaries really plan to do with it…

As for the woman on the right side of the composition, she is connected to the cross in a very important way.

You can read the story for yourself here on my website's blog:

When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10^–15 seconds). The spin, or angular momentum, of the electrons in the material, thus disappears almost instantly. Yet all that angular momentum cannot simply be lost. It must be conserved – somewhere.

Thanks to new ultrafast electron diffraction experiments, researchers at the University of Konstanz in Germany have now found that this “lost” angular momentum is in fact transferred from the electrons to vibrations of the material’s crystal lattice within a few hundred femtoseconds. The finding could have important implications for magnetic data storage and for developments in spintronics, a technology that exploits electron spins to process information without using much power.

In a ferromagnetic material, magnetism occurs because the magnetic moments of the material’s constituent atoms align parallel to each other. The atoms and their electrons then act as elementary electromagnets, and the magnetic fields are produced mainly by the spin of the electrons.

Because an ultrashort laser pulse can rapidly destroy this alignment, some scientists have proposed using such pulses as an off switch for magnetization, thereby enabling ultra-rapid data processing at frequencies approaching those of light. Understanding this ultrafast demagnetization process is thus crucial for developing such applications as well as for better understanding the foundations of magnetism.

In case you had not noticed, computers are hot—literally. A laptop can pump out thigh-baking heat, while data centers consume an estimated 200 terawatt-hours each year—comparable to the energy consumption of some medium-sized countries. The carbon footprint of information and communication technologies as a whole is close to that of fuel used in the aviation industry. And as computer circuitry gets ever smaller and more densely packed, it becomes more prone to melting from the energy it dissipates as heat.

Now physicist James Crutchfield of the University of California, Davis, and his graduate student Kyle Ray have proposed a new way to carry out computation that would dissipate only a small fraction of the heat produced by conventional circuits. In fact, their approach, described in a recent preprint paper, could bring heat dissipation below even the theoretical minimum that the laws of physics impose on today’s computers. That could greatly reduce the energy needed to both perform computations and keep circuitry cool. And it could all be done, the researchers say, using microelectronic devices that already exist.

In 1961 physicist Rolf Landauer of IBM’s Thomas J. Watson Research Center in Yorktown Heights, N.Y., showed that conventional computing incurs an unavoidable cost in energy dissipation—basically, in the generation of heat and entropy. That is because a conventional computer has to sometimes erase bits of information in its memory circuits in order to make space for more. Each time a single bit (with the value 1 or 0) is reset, a certain minimum amount of energy is dissipated—which Ray and Crutchfield have christened “the Landauer.” Its value depends on ambient temperature: in your living room, one Landauer would be around 10–21 joule. (For comparison, a lit candle emits on the order of 10 joules of energy per second.)

ALMATY, March 30 (Reuters) - A U.S. astronaut and two Russian cosmonauts safely landed in Kazakhstan on Wednesday after leaving the International Space Station aboard the same capsule despite heightened antagonism between Moscow and Washington over the conflict in Ukraine.

The flight -- carrying NASA's Mark Vande Hei and Russians Anton Shkaplerov and Pyotr Dubrov back to Earth -- had been closely watched to determine whether escalating strife had spilled over into longtime cooperation in space between the two former Cold War adversaries.

Russian space agency Roscosmos broadcast footage of the landing from the Kazakh steppe and said a group of technical and medical specialists had been dispatched to help the astronauts out of the capsule.

"The crew is feeling good after landing, according to rescuers," Roscosmos chief Dmitry Rogozin wrote on Telegram messenger.

Vande Hei, who had completed his second ISS mission, logged a U.S. space-endurance record of 355 consecutive days in orbit, surpassing the previous 340-day record set by astronaut Scott Kelly in 2016, according to NASA.

With all due respect to the recently departed former Secretary of State Madeline Albright, she started using the phrase "indispensable nation" after political reporter Sydney Blumenthal coined it. From Foreign Policy Magazine:

In his memoir of the Clinton presidency, The Clinton Wars, Blumenthal elaborated on what the phrase was intended to represent: “Only the United States had the power to guarantee global security: without our presence or support, multilateral endeavors would fail.” Albright, then secretary of state, began using the phrase often, and most prominently in February 1998, while defending the policy of coercive diplomacy against Iraq over its limited cooperation with U.N. weapons inspectors when, during an interview on the “Today Show,” she said: “If we have to use force, it is because we are America; we are the indispensable nation. We stand tall and we see further than other countries into the future, and we see the danger here to all of us.”

The Myth of the Indispensable Nation, Micah Zenko, Foreign Policy

Though politically expedient, and in the parlance of activism, it "chants" well, we're not indispensable, nor are we exceptional. We allowed the worst of a pandemic to spread by ineptitude and Twitter addiction, science denialism, and conspiracy theory. Since the introduction of cable news and siloes of news consumption, we have citizens that believe in different versions of reality. It puts the "United States" in the realm of the oxymoron.

Now, we're at this grim milestone. Conservatives live to push buttons, "own the libs," grift off culture issues, and keep their constituents at high levels of anxiety and anger with right-wing echo chambers to ensure they vote for them to "own the libs." Progressives think high-minded logic, social media presence, "woke-ness," diversity, equity, and inclusion by proximity will produce a Star Trek utopia, because of high-minded logic. I purposely made each perspective a grammatical ouroboros. We're at a grim milestone because our major political parties have wholly different means of evaluating reality, and because compromise is frowned upon: "DINO, RINO." There are dark, nefarious forces that only the well-connected to Q-drops or Alex Jones can decipher.

431,000 non-farm jobs were added, and the unemployment rate fell to 3.6%. Yet, the 46th president's approval numbers are in the toilet largely because he isn't as entertaining as the last spastic, pathologically lying, hand-waving caricature of a mob boss with a dead ferret toupee, a metaphor for a lifetime of hiding hard truths from himself.

We are codependent on being perpetually angry, and not wed to the idea of speaking to our neighbors who might not consume the same media. We thus base our understanding of the world and facts on separate lenses we view reality through.

Tom Nichols, former professor at Annapolis Naval Academy, opined about "The Death of Expertise: The Campaign Against Established Knowledge and Why It Matters" in 2017, and it doesn't look like we've turned a corner from that analysis of our national death spiral. Because we can "Google it," we're a Dunning-Kruger nation of narcissists and debase people who put a lot of work into understanding how the world works. We are a byword and a proverb. We are Guy Debord's "Society of the Spectacle."

“The whole idea of a democratic application of skepticism is that everyone should have the essential tools to effectively and constructively evaluate claims to knowledge.”

Laura Jackson feels the loss of her husband Charlie like she is missing a part of herself. He died of COVID early in the pandemic, on May 17, 2020, just weeks after the couple celebrated his 50th birthday. Charlie was an Army veteran who served in Iraq during Desert Storm, and Laura finds herself returning to images of war and loss—to those who have lost a limb but still feel its phantom tingle, who unthinkingly reach for a glass of water or try to step out of bed before realizing what has been lost forever. Even now she still turns to find Charlie, eager to share a joy or a disappointment, only to remember with a jolt that there is a missing space where he once was.

“I don’t know that you ever get over it,” says Jackson, who lives in Charlotte, N.C. “Your person who was supposed to be there for life—to have that tragically ripped away has been a huge, huge adjustment to make.”

The U.S. will record one million confirmed deaths from COVID in the next several weeks. This toll is likely an undercount because there are more than 200,000 other excess deaths that go beyond typical mortality rates, caused in part by the lingering effects of the disease and the strain of the pandemic. These immense losses are shaping our country—how we live, work, and love, how we play and pray and learn and grow.

“We will see the rippling effects of the pandemic on our society and the way it impacts individuals for generations,” says Nyesha Black, director of demographic research at the University of Alabama. “This is definitely a huge marker in the way we will think about society moving forward—it will be that anchor event.” COVID has become the third leading cause of death in the U.S., after heart disease and cancer.

These deaths have wide-ranging consequences. The effects on children may be the longest-lasting. In the U.S., an estimated 243,000 children have lost a caregiver to COVID—including 194,000 who lost one or both parents—and the psychological and economic aftershocks can have lifetime negative impacts on their education and career.

Researchers in the US have developed a perovskite-based device that could be used to create a high-plasticity architecture for artificial intelligence. The team, led by Shriram Ramanathan at Purdue University, has shown that the material’s electronic properties can be easily reconfigured, allowing the devices to function like artificial neurons and other components. Their results could lead to more flexible artificial-intelligence hardware that could learn much like the brain.

Artificial intelligence systems can be trained to perform a task such as voice recognition using real-world data. Today this is usually done in software, which can adapt when additional training data are provided. However, machine learning systems that are based on hardware are much more efficient and researchers have already created electronic circuits that behave like artificial neurons and synapses.

However, unlike the circuits in our brains, these electronics are not able to reconfigure themselves when presented with new training information. What is needed is a system with high plasticity, which can alter its architecture to respond efficiently to new information.

An excerpt. The longer article piece is at the link following.

The COVID-19 pandemic has not only killed a large number of people—approximately 5.5 million worldwide at the time Physics Today went to press in mid-January—it has also disrupted life in a fundamental, nonperturbative manner, forcing large-scale changes in human behavior from without.

It was difficult at the beginning of 2020 to anticipate the great COVID-19 calamity awaiting the world. In February of that year, I was apparently among the first people to have urged the leadership of the American Physical Society to cancel its upcoming March Meeting in Denver, which APS finally did at the last moment after considerable hesitancy.

The logistics of canceling a meeting of 10 000 people right before the event are not trivial. But given the crowd density in APS March Meetings, it is reasonable to assume that the 2020 event would have led to a few thousand COVID-19 cases just among the physicist attendees. Overall, it may have led to many tens of thousands, perhaps even hundreds of thousands, of cases, if not more. That estimate is based on research related to the now-infamous Boston Biogen superspreader conference in late February 2020. Within a month, roughly 100 people in Massachusetts who either went to the conference or were a household contact of someone who went tested positive. The genetic-code-based investigation estimated that the event led to 300 000 COVID-19 cases worldwide by the beginning of the following November. APS made the right call in canceling the meeting.
