Abstract
Hydrogel-polymer hybrids have been widely used for various applications such as biomedical devices and flexible electronics. However, the current technologies constrain the geometries of hydrogel-polymer hybrid to laminates consisting of hydrogel with silicone rubbers. This greatly limits the functionality and performance of hydrogel-polymer–based devices and machines. Here, we report a simple yet versatile multimaterial 3D printing approach to fabricate complex hybrid 3D structures consisting of highly stretchable and high–water content acrylamide-PEGDA (AP) hydrogels covalently bonded with diverse UV curable polymers. The hybrid structures are printed on a self-built DLP-based multimaterial 3D printer. We realize covalent bonding between AP hydrogel and other polymers through incomplete polymerization of AP hydrogel initiated by the water-soluble photoinitiator TPO nanoparticles. We demonstrate a few applications taking advantage of this approach. The proposed approach paves a new way to realize multifunctional soft devices and machines by bonding hydrogel with other polymers in 3D forms.

Quantum Jumps...

8392875501?profile=RESIZE_584x

Topics: Modern Physics, Quantum Mechanics, Theoretical Physics

Quantum mechanics, the theory that describes the physics of the universe at very small scales, is notorious for defying common sense. Consider, for instance, the way that standard interpretations of the theory suggest change occurs in the quantum turf: shifts from one state to another supposedly happen unpredictably and instantaneously. Put another way, if events in our familiar world unfolded similarly to those within atoms, we would expect to routinely see batter becoming a fully baked cake without passing through any intermediate steps. Everyday experience, of course, tells us this is not the case, but for the less accessible microscopic realm, the true nature of such “quantum jumps” has been a major unsolved problem in physics.

In recent decades, however, technological advancements have allowed physicists to probe the issue more closely in carefully arranged laboratory settings. The most fundamental breakthrough arguably came in 1986, when researchers for the first time experimentally verified that quantum jumps are actual physical events that can be observed and studied. Ever since steady technical progress has opened deeper vistas upon the mysterious phenomenon. Notably, an experiment published in 2019 overturned the traditional view of quantum jumps by demonstrating that they move predictably and gradually once they start—and can even be stopped midway.

That experiment, performed at Yale University, used a setup that let the researchers monitor the transitions with minimal intrusion. Each jump took place between two energy values of a superconducting qubit, a tiny circuit built to mimic the properties of atoms. The research team used measurements of “side activity” taking place in the circuit when the system had lower energy. This is a bit like knowing which show is playing on a television in another room by only listening for certain keywords. This indirect probe evaded one of the top concerns in quantum experiments—namely, how to avoid influencing the very system that one is observing. Known as “clicks” (from the sound that old Geiger counters made when detecting radioactivity), these measurements revealed an important property: jumps to the higher energy were always preceded by a halt in the “keywords,” a pause in the side activity. This eventually permitted the team to predict the jumps’ unfolding and even to stop them at will.

Snake vision inspires pyroelectric material design

Bioinspiration and biomimicry involve studying how living organisms do something and using that insight to develop new technologies. Pit vipers have two special organs on their heads called loreal pits that allow them to “see” the infrared radiation given off by their warm-blooded prey. Now, Pradeep Sharma and colleagues have worked out that the snakes use cells that act as a soft pyroelectric material to convert infrared radiation into electrical signals that can be processed by their nervous systems. As well as potentially solving a longstanding puzzle in snake biology, the work could also aid the development of thermoelectric transducers based on soft, flexible structures rather than stiff crystals.

The Path Forward...

Science, as Carl Sagan wrote, has to be our "candle in the dark."

The Scientific Method we developed as a hunter-gatherer species. The tools of hunter-gatherers were utilitarian and pragmatic. Our ancestors observed things and noticed patterns. They made mental notes of these patterns and codified them through rituals, customs, and behaviors into distinct cultures defined by these traditions. Some kept this knowledge in secret, esoteric, as any knowledge is power over others. This probably is the reason why we're so suspicious of any change in what was, or is new knowledge.

Many first-responders are BIPOC, so the resistance to it, probably from the apprehension around the Tuskegee Experiment, has an understandable history, but it's still alarming. We can wear masks. We can contact trace. We can socially distance. We can take the Pfizer, Moderna, or AstraZeneca variants of the vaccine, and mitigate this more quickly.

Or, we can guarantee after a long dark winter, a long slog through the spring, summer, and fall. Herd immunity isn't by brute force: it is intentionally engineered with vaccines.

WASHINGTON — Authorities are reporting early shipments of the COVID 19 vaccine will not cover all essential personnel who are supposed to be first in line to get it. The CDC's immunization advisory panel voted Tuesday to give the first round of COVID-19 vaccines to health care personnel and long-term care facility residents.

Hundreds of thousands of frontline medical workers are at the top of that list. But surveys are showing that not all are eager to be first.

While 63% of health care workers reported to the U.S. Centers for Disease Control that they would accept the vaccine, the agency is concerned about the large numbers who are hesitant. The American Nurses Foundation is reporting 36% of nurses surveyed said they would not voluntarily get the COVID-19 vaccine once it's deployed.

Carbon sequestration involves a lot of technology, or it can involve what Earth did before we discovered technology: plant more trees.

Forty-nine million years ago, a small aquatic fern called Azolla wrested control of Earth’s climate. At the time, the landlocked Arctic Ocean developed a surface layer of fresh water, which allowed the ferns to grow unchecked in a wide-open environment. Billions of tons of plants died and sank to the bottom of the ocean, taking with them the carbon they had sucked from the air when they were alive. 

The consequences were extreme. Geologic evidence indicates that atmospheric carbon dioxide levels plummeted more than 80 percent over 800,000 years, sharply ratcheting down Earth’s thermostat. Prior to the inferred “Azolla Event,” most of the globe was lush and tropical. Afterward, the Arctic cooled by nearly 40 degrees Fahrenheit, the poles froze, and our planet entered a lurching cycle of ice ages that continues to this day. 

How to Bury Carbon? Let Plants Do the Dirty Work, Cory S. Powell, Cold Springs Harbor Laboratory

This seems simple enough, but politicians like Jair Bolsonaro apparently came to power much like our one-term Neo-fascist did: lifted to the office by right-wing Christian zealots in Brazil, particularly of the megachurch kind. From a dominionist view, carbon sequestration shows a "lack of faith." Forty-nine million years ago is a long way from a mere guestimate of ten-thousand years. Burning the Amazon, like for many cheering for Armageddon hastens the Apocalypse, and the Second Coming. It is thus, anathema.

I follow Politics and Prose on YouTube. David K. Johnston gave a speech at their bookstore some time ago on his book: "The Making of Donald Trump." Many things weren't a revelation to me, but one thing, in particular, stuck with me.

People the world over are afraid. Con artists, fascists, and strongmen play on fear.

I'm talking pre-pandemic afraid: afraid of change, afraid of diversity, afraid their particular sacred texts do not line up neatly with new scientific discoveries; afraid of their traditions being challenged in the light of Sagan's candle. Such fear gives political power to strongmen (the antonym more accurate) that assure their crowds on their rise to power that they will return those fearful of change to a "golden age of greatness," which they never really define. The other common thing is there is a scapegoated "other" on which all blame for everything wrong is laid. That is the history of the scapegoat, by the way. For humans, it leads to disdain, disregard, murder, and genocide.

For an otherwise intelligent species, that can lead to extinction.

A preprint paper in ArXiv gives the grim estimate that intelligent species over long stretches of time eventually annihilate themselves. I would really like us all to be the rare exceptions to this possible rule.

Dark Winter, Brighter Spring...

Topics: Biology, Civics, Civil Rights, COVID-19, Existentialism, Human Rights

I have taken the following vaccines this year: Pneumonia, Seasonal Influenza (Flu), Shingles in two booster shots.

Therefore, I am very likely to take the Coronavirus vaccine either offered by Pfizer or Moderna.

Pfizer is pushing back on the Trump administration's suggestion that the company is having trouble producing its COVID-19 vaccine, saying it's ready to ship millions more doses – once the government asks for them. As the company spoke out, several states said their vaccine allocations for next week have been sharply reduced.

Here's what the key players are saying about a complicated situation:

What Pfizer says

"Pfizer is not having any production issues with our COVID-19 vaccine, and no shipments containing the vaccine are on hold or delayed," CEO Albert Bourla said via Twitter. His company says it has completed every shipment the U.S. government has requested.

"We have millions more doses sitting in our warehouse but, as of now, we have not received any shipment instructions for additional doses," Pfizer said in a statement.

The company also noted that in the past week, it shipped 2.9 million doses of the vaccine it developed with BioNTech in what is widely seen as a breakthrough in the nation's fight against the coronavirus.

Pfizer Says Millions Of Vaccine Doses Are Ready, But States Say Shipments Were Cut, Bill Chappell, NPR

Unlike the 1918 pandemic, I don't think it will take us a decade to come to some sense of normalcy. I am concerned, from a cultural perspective, that the vaccine spreads equitably.

We have a reason to be suspicious. The Tuskegee Experiment happened over four decades, affected hundreds of lives, allowing syphilis to infect men, women, and children. It makes trusting authorities with our lives a bit problematic. As I've said, if it helps anyone reading this entry, I will take the vaccine. I would like to get back to some sense of normalcy.

The revelation of the recent Russian hacks is the equivalent of a Cyber Pearl Harbor. Our nuclear triad material, three states (including Austin, Texas), the Central Intelligence Agency, Treasury, NASA, Commerce, et al. This is a stickup. Think the city, lights: sewage. Like a burglar, we could all be held hostage by a foreign power. To paraphrase a false claim attributed to Nikita Khrushchev, Putin could literally "bury us without firing a shot."

The shenanigans of the current obtuse, malignant, narcissistic, and incompetent administration will come to an end. Vaccines will go out, modeled by an incoming administration that like previous democratic ones before them, have to shovel the country out of the smoldering ruin that the previous republican one left the country in. They will, of course, delay vaccines, they will of course, try to sabotage on the way out. They are the steroids equivalent of Clinton-to-Bush removing the W keys, and costing the government approximately $15,000. It was disappointing and sophomoric. This stunt is petty, malevolent, and deadly. We have crossed the Rubicon of 300,000 dead Americans. At a rate of a 9/11 per day, we'll reach 400,000 by inauguration. Delay during a pandemic will kill more Americans, but I guess that's not a big concern to a malignant narcissist.

But I am hopeful for a brighter spring.

Mango Mussolini can do a lot of damage in 33 days, but it's 33 days at noon when he loses access to the nuclear football, he loses the presidential immunity that protects him from an indictment, not that Letitia James, Cyrus Vance, SDNY, or EDNY are bothered by his threats of family and self pardons. His crimes in New York are state felonies, likely involving inflating his wealth, or decreasing it when it suited him. We'll likely find out he's not as rich as he claims to be. He cashed a series of diminishing value checks sent as a gag by Spy Magazine, proving himself a bit player in the New York Real Estate market. He'll need every penny he's grifting from his deluded followers to stay out of prison. Not that I'm sympathetic: but grift on this constant level has to be exhausting, and depleting of finance, and bodily constitution.

The evil energizer bunny has to run out of gas sometimes. His tweets will reach a limited audience. Cities that haven't YET gotten paid for his previous rallies will refuse to book him. He's proposing bringing back The Apprentice because his "power" is his celebrity, and that dwindles quickly without cameras on you constantly. He can call it Apprentice, 2024: Finding a Vice President (a tacit admittance Pence didn't help him win re-election). Several sources say Twitter might finally remove him, not the conviction to "do the right thing," just that if his followers dwindle, they have no one to gather metadata from for marketing purposes. It's business, and a one-term president probably isn't good for the bottom-line.

That's all fine and good, Donald unless you're spending your evenings at Riker's. Maybe they'll station you at the Queens Detention Complex. He can see the old neighborhood, while the rest of us heal from his madness. We will get through this.

That's it for this year. See you in January 2021.

For decades, most physicists have agreed that string theory is the missing link between Einstein's theory of general relativity, describing the laws of nature at the largest scale, and quantum mechanics, describing them at the smallest scale. However, an international collaboration headed by Radboud physicists has now provided compelling evidence that string theory is not the only theory that could form the link. They demonstrated that it is possible to construct a theory of quantum gravity that obeys all fundamental laws of physics, without strings. They described their findings in Physical Review Letters last week.

When we observe gravity at work in our universe, such as the motion of planets or light passing close to a black hole, everything seems to follow the laws written down by Einstein in his theory of general relativity. On the other hand, quantum mechanics is a theory that describes the physical properties of nature at the smallest scale of atoms and subatomic particles. Though these two theories have allowed us to explain every fundamental physical phenomenon observed, they also contradict each other. As of today, physicists have severe difficulties to reconcile the two theories to explain gravity on both the largest and smallest scale.

Invisible structures generated by gravitational interactions in the Solar System have created a "space superhighway" network, astronomers have discovered.

 

These channels enable the fast travel of objects through space and could be harnessed for our own space exploration purposes, as well as the study of comets and asteroids.

 

By applying analyses to both observational and simulation data, a team of researchers led by Nataša Todorović of Belgrade Astronomical Observatory in Serbia observed that these superhighways consist of a series of connected arches inside these invisible structures, called space manifolds - and each planet generates its own manifolds, together creating what the researchers have called "a true celestial autobahn."

 

This network can transport objects from Jupiter to Neptune in a matter of decades, rather than the much longer timescales, on the order of hundreds of thousands to millions of years, normally found in the Solar System.

 

Finding hidden structures in space isn't always easy, but looking at the way things move around can provide helpful clues. In particular, comets and asteroids.

 

There are several groups of rocky bodies at different distances from the Sun. There's the Jupiter-family comets (JFCs), those with orbits of less than 20 years, that don't go farther than Jupiter's orbital paths.

 

Centaurs are icy chunks of rocks that hang out between Jupiter and Neptune. And the trans-Neptunian objects (TNOs) are those in the far reaches of the Solar System, with orbits larger than that of Neptune.

It’s not just your storage unit that’s packed to the gills. According to a new study, the mass of all our stuff—buildings, roads, cars, and everything else we manufacture—now exceeds the weight of all living things on the planet. And the amount of new material added every week equals the total weight of Earth’s nearly 8 billion people.

“If you weren’t convinced before that humans are dominating the planet, then you should be convinced now,” says Timon McPhearson, an urban ecologist at the New School who was not involved with the research. “This is an eye-catching comparison,” adds Fridolin Krausmann, a social ecologist at the University of Natural Resources and Life Sciences, Vienna, who also was not involved in the work.

There are many measures of humanity’s impact on the planet. Fossil fuels have sent greenhouse gases soaring to levels not seen in at least 800,000 years. Agriculture and dwellings have altered 70% of the land. And humans have wiped out untold numbers of species in an emerging great extinction. The transformations are so great that researchers have declared we’re living in a new human-dominated age: the Anthropocene.</em>

Systems biologist Ron Milo of the Weizmann Institute of Science went looking for a new gauge of our impact. He and his colleagues synthesized previous estimates of the biomass of living plants for each year between 1900 and 2017. Those estimates account for about 90% of all living things and are based on field research and computer modeling. From 1990 onward, they also include data from satellites, which researchers have used to track global vegetation.

Reality-Truth...

Leonard Nimoy as Spock from "Amok Time," TOS, first aired September 15, 1967

 

Topics: Civics, Civil Rights, Human Rights, Politics, Star Trek

 

I've been finishing up the semester. I passed my preliminary exam. Now I'm working on refining my research question for my dissertation proposal, due late spring. I usually take a break from blogging around the holidays, and as my Dean put it, dissertations proposals are "a bear." So don't be surprised if I take a blog break for LONG stretches.

 

o'thia
Literally defined as "reality-truth" in Vulcan religion/philosophy, methods of emotional self-control, and teachings of pacifism. The term o'thia is also known simply as logic. Note: there is an error on the wiki - cthia, versus o'thia. See TOS novel: Spock's World, by Diane Duane. See beta wiki: https://memory-beta.fandom.com/wiki/Vulcan_language

 

As I type this, the FDA meeting on the Pfizer version of the coronavirus vaccine has concluded. They have taken the first steps towards approving the vaccine for distribution in America. The first woman in the world to receive it was a 90-year-old grandmother in Bristol. As she gave her arm and consent, many even in the UK expressed misplaced skepticism, expressing their version of European "anti-vax" sentiments. African Americans are still feeling the sting of the Tuskegee Experiment, decades later, and don't trust anything the current administration might have produced after waves of destructive behavior, destroying what was marginal "norms," but the pandemic has shown and is showing, we were not "normal," and we still aren't. The majority of WASP-C (White, Anglo Saxon Protestant Cisgender) countries are scarfing up vaccine supplies because they have the WEALTH to do so. We are still behaving carnally, like warring tribes over the next hill. The pandemic has revealed our world is imbalanced by racism and income inequality. A lot of the epidemics and pandemics stem from people trying their best to survive under circumstances they did not design for themselves. You can't complain about anyone eating a bat any more than you can about someone eating chitterlings and high-salt hog products when the scraps were literally all African Americans had to eat. See Umar Haque's article: "How Covid Proves the World is Even More Racist Than You Think." Start getting used to the term "vaccine nationalism." It's short-sighted: you can't do any international travel for business, or pleasure if developing countries - where we get a lot of precious metals - are still in lockdown.

 

Star Trek is modern mythology, born during the turbulent 1960s when there were the struggle for civil rights, women's rights, LGBT rights (Stonewall), civil unrest, assassinations, and the Cold War with the Soviet Union, "duck-and-cover" drills being as part of the school curriculum as masks are now. Gene Roddenberry envisioned a world in the far future, with fantastic technologies and cooperation among humanity that from September 8, 1966, to June 3, 1969, he obviously hadn't see demonstrated. In many ways, we're trying to "live up" to the optimistic (some would say Pollyannaish) vision today.

 

Star Trek inspired many P.E.E.R.s (People Excluded due to Ethnicity and Race, see David Asai, 2020 here, and here) into STEM, Dr. Ronald E. McNair, for example, and myself.

 

Spock particularly inspired me. He wasn't just Vulcan: he was biracial, not just of two cultures, but two worlds. From the canon, he seemed to experience xenophobia and insults from other "pure" Vulcans, as well as snarky humans like Dr. Leonard McCoy. Seeing myself in the outsider, "the other" in Science Officer Spock wasn't even a little stretch. Empathy for his fellow Vulcan's and some human's racism during the turbulent 1960s was easy.

We are a country in the aftermath of being gaslighted by a man his clinical psychologist niece says is so delusional, he can gaslight himself. We are a country in the aftermath of four-hundred years of gaslighting between "superior" and "inferior." "Reality-truth" is anathema to him and his cult following, primed by forty-years of AM talk radio and four-hundred years of generational brainwashing. The Fairness Doctrine wasn't repealed by Reagan, but it was abandoned in 1987 during his administration's lame-duck years. It affected radio broadcast licenses, so you can say this probably led to Rush Limbaugh and right-wing talk radio. Fox News is television, thus unrestrained by whether we had a fairness doctrine when they arrived in 1996 or not. The Texas AG and seventeen other AG's - all WASP-C males (White, Anglo Saxon Protestant-Cisgender) have filed a frivolous lawsuit to overturn the 2020 election results because the BIPOC (Black, Indigenous People Of Color, and P.E.E.R.s among them) have no votes that they deem credible unless they vote for republicans.

 

[Chief Justice Roger B.] Taney -- a staunch supporter of slavery and intent on protecting southerners from northern aggression -- wrote in the Court's majority opinion that, because Scott was black, he was not a citizen and therefore had no right to sue. The framers of the Constitution, he wrote, believed that blacks "had no rights which the white man was bound to respect; and that the negro might justly and lawfully be reduced to slavery for his benefit. He was bought and sold and treated as an ordinary article of merchandise and traffic, whenever profit could be made by it." PBS - Dred Scott case: the Supreme Court decision, 1857

 

Dr. Mary Trump is the author of "Too Much, and Never Enough: How My Family Created the World's Most Dangerous Man." She's apparently working on a follow-up book on the country's collective trauma due to her uncle's incompetence, and more likely, his many undiagnosed mental disorders. Also, as I listened to her View interview, she wants to talk about how we as a nation - not the BIPOC, or P.E.E.R.s - have collectively ignored our past and never reckoned with the slaughter of Native First Nation Peoples, the kidnap, rape, and slaughter-at-will of the African Diaspora, to the point the current dwindling majority can't see me any more than Taney did my ancestor, Dred Scott: we have no rights they are bound to respect, and our vote is by definition "fraudulent," unless we vote for them as "masters."

 

"Reality-truth" - o'thia - saved the mythical Vulcans from self-annihilation.

 

We might want a steady diet of o'thia if we want to survive as a species.

 

"Wakanda will no longer watch from the shadows. We can not. We must not. We will work to be an example of how we, as brothers and sisters on this earth, should treat each other. Now, more than ever, the illusions of division threaten our very existence. We all know the truth: more connects us than separates us. But in times of crisis, the wise build bridges, while the foolish build barriers. We must find a way to look after one another as if we were one single tribe."

Iran's most senior nuclear scientist Mohsen Fakhrizadeh has been assassinated near the capital Tehran, the country's defense ministry has confirmed.

Fakhrizadeh died in hospital after an attack in Absard, in Damavand county.

Iran's Foreign Minister Mohammad Javad Zarif has condemned the killing "as an act of state terror".

Western intelligence agencies believe Fakhrizadeh was behind a covert Iranian nuclear weapons program.

"If Iran ever chose to weaponize (enrichment), Fakhrizadeh would be known as the father of the Iranian bomb," one Western diplomat told Reuters news agency in 2014.

Iran insists its nuclear program is exclusively for peaceful purposes.

But news of the killing comes amid fresh concern about the increased amount of enriched uranium that the country is producing. Enriched uranium is a vital component for both civil nuclear power generation and military nuclear weapons.

Yes, just like something out of Marvel's Captain America. According to reports by U.S. intelligence, China has conducted human testing on members of the People's Liberation Army with the ambitious goal of developing soldiers with enhanced biological capabilities.

Though it may sound like something out of science fiction, emerging technologies capable of augmenting the human body paired with the rapidly evolving world of genome-editing could arguably spawn the dawn of super-humans.

Concepts like artificial intelligence symbiosis, bionic body parts, and self-regenerating limbs are not too far off into the future.

Though the idea of getting your hands on some highly coveted Marvel-Esque superpowers sounds exciting, there are some real-world fears and ethical questions that need to be asked. Should we if we can?

In July, we were estimated losing a person a minute to COVID-19. We may now lose the equivalent of a 9/11 per day by Christmas. Bah, humbug!

In the constitutional "peaceful transfer of power," you would think the current occupant of the Oval Office would be laser-focused on the pandemic. He would have his agencies coordinating with the incoming administration to ensure its success, and minimize the loss of life due to a virus that spreads exponentially. You would think his Oath of Office would come to mind, the whole "protect and defend the Constitution against all enemies, foreign, and domestic." That the safety of the nation and its citizens would be his highest priority.

Dude, you don't know our current occupant. He's playing president like he played a billionaire. He's never been either one.

No action on the assassination of an Iranian nuclear scientist, no condemnation of the act, or sanctions on an ally that approved this action, nor officially logging our disapproval.

China is on the verge of fielding "Captain China" supermen on a future battlefield we may find our soldiers dying on. They're already on the verge of technological supremacy without augments. Their fascination with Nazi lawyer Carl Schmitt is disturbing.

Of course, his priorities are arguing an election that he clearly lost.

 

Abstract

The aim of this paper is to demonstrate that China's economic and military transformation, under the current Communist regime, has the potential to seriously threaten the future security of Canada and the West. The paper first looks at the economic reforms that have radically changed the Chinese economy. Then, the paper presents the significant changes that have taken place concerning military strategy, equipment modernization, and power projection capability. The strategic view and policies of Canada and the US are discussed in light of these changes and other recent incidents. The paper then presents the argument that there are three potential problem areas in which China could possibly threaten the West. The paper concludes by noting that China is a Communist country that is dissatisfied with its status in the world and that the West must not be naive to its intentions and ambitions.

The economic conditions before the first and second world wars were similarly dire, and related to each other. The gist of each causing massive losses of life (inclusive of the 1918 pandemic) was arrogance and greed.

We live in a cartoon. We think our actions are recoverable and survivable. We think there's a "Season Two" to stupidity. We think that minerals we've given agency over our lives, spewed as the guts of stars parsecs away are valuable enough to hoard, steal, and kill over.

We elect caricatures of gangsters to high office: sociopaths with Twitter followers that are equally psychotic. We're at the Entropy of our political experiment. Chaos is kind of unrecoverable without benevolent aliens and fictional warp signatures.

He's running a con. He's ALWAYS running a con. The con started with Reagan: "government is the problem" is as catchy and myopic a slogan as "defund the police." What does either one mean? I don't think officers should show up to a mental health crisis with guns blazing: that usually doesn't turn out too well. Was there a libertarian rocketeer that had a cost-effective method of getting to the moon? Was there some unknown genius living in his mom's basement that had a better solution than ARPANET (that became the Internet)?

He's making far more money in small-dollar donations by losing the election, whining about it was "rigged," and putting out 46-minute bullshit infomercials to morons than winning it. As a malignant narcissist, he could care LESS who his rhetoric influences to commit violence, whether they're Republicans, Independents, or Democrats.

As he witnessed the first detonation of a nuclear weapon on July 16, 1945, a piece of Hindu scripture ran through the mind of Robert Oppenheimer: “Now I am become Death, the destroyer of worlds”. It is, perhaps, the most well-known line from the Bhagavad-Gita, but also the most misunderstood.

In Hinduism, which has a non-linear concept of time, the great god is not only involved in the creation, but also the dissolution. In verse thirty-two, Krishna speaks the line brought to global attention by Oppenheimer. "The quotation 'Now I am become death, the destroyer of worlds', is literally the world-destroying time,” explains Thompson, adding that Oppenheimer’s Sanskrit teacher chose to translate “world-destroying time” as “death”, a common interpretation. Its meaning is simple: irrespective of what Arjuna does, everything is in the hands of the divine.

"Arjuna is a soldier, he has a duty to fight. Krishna, not Arjuna will determine who lives and who dies and Arjuna should neither mourn nor rejoice over what fate has in store, but should be sublimely unattached to such results,” says Thompson. “And ultimately the most important thing is he should be devoted to Krishna. His faith will save Arjuna's soul." But Oppenheimer, seemingly, was never able to achieve this peace. "In some sort of crude sense which no vulgarity, no humour, no overstatements can quite extinguish," he said two years after the Trinity explosion, "the physicists have known sin; and this is a knowledge which they cannot lose.”

Quasiparticles, and Graphene...

Researchers at the University of Manchester in the UK have identified a new family of quasiparticles in superlattices made from graphene sandwiched between two slabs of boron nitride. The work is important for fundamental studies of condensed-matter physics and could also lead to the development of improved transistors capable of operating at higher frequencies.

In recent years, physicists and materials scientists have been studying ways to use the weak (van der Waals) coupling between atomically thin layers of different crystals to create new materials in which electronic properties can be manipulated without chemical doping. The most famous example is graphene (a sheet of carbon just one atom thick) encapsulated between another 2D material, hexagonal boron nitride (hBN), which has a similar lattice constant. Since both materials also have similar hexagonal structures, regular moiré patterns (or “superlattices”) form when the two lattices are overlaid.

If the stacked layers of graphene-hBN are then twisted, and the angle between the two materials’ lattices decreases, the size of the superlattice increases. This causes electronic band gaps to develop through the formation of additional Bloch bands in the superlattice’s Brillouin zone (a mathematical construct that describes the fundamental ideas of electronic energy bands). In these Bloch bands, electrons move in a periodic electric potential that matches the lattice and does not interact with one another.

Truthiness, to Truth Decay...

Truthiness is the belief or assertion that a particular statement is true based on the intuition or perceptions of some individual or individuals, without regard to evidencelogicintellectual examination, or facts. Truthiness can range from ignorant assertions of falsehoods to deliberate duplicity or propaganda intended to sway opinions.

The concept of truthiness has emerged as a major subject of discussion surrounding U.S. politics during the 1990s and 2000s because of the perception among some observers of a rise in propaganda and a growing hostility toward factual reporting and fact-based discussion.

American television comedian Stephen Colbert coined the term truthiness in this meaning as the subject of a segment called "The Wørd" during the pilot episode of his political satire program The Colbert Report on October 17, 2005. By using this as part of his routine, Colbert satirized the misuse of appeal to emotion and "gut feeling" as a rhetorical device in contemporaneous socio-political discourse.

Roger Ailes was very explicit as to why he wanted, and created Fox News: he wanted a news outlet friendly to conservative interests in the wake of Watergate, and the resignation of President Richard Nixon. I don't think we realize how astonishing that was, and that we've mythologized those times as "halcyon days" of yore.

Richard Nixon ran on "law and order," and the fear of violence in the wake of the deaths of Martin Luther King and Robert Kennedy. He subtly stoked white grievance, the so-called "Southern Strategy," infamously described by political operative Lee Atwater. It worked. He rode to power in 1968, and a landslide forty-nine out of fifty state win in 1972, where he became the first Republican to sweep the south.

Nixon didn't need the plumbers to break into the DNC headquarters Watergate building, but there's evidence he used government resources instructing them to do so. His Vice President, Spiro Agnew, was accepting "bags of money" at the White House - as he did as governor of Maryland - to do political "favors" on Capitol Hill. For all intents and purposes, that is bribery. Nowadays, they attach lawyers to it, and call it lobbying.

The Justice Department was in a conundrum: if they indict the sitting president for an illegal break-in, they have to indict the sitting Vice President for usury. Plus, that pesky thing called The Constitution said if removed from office, the next in line was the Speaker of the House of Representatives, then, as now, a Democrat. The "memo" came out, without legal standing, or precedence, that you "cannot indict a sitting president."

We did not have cable television, cell phones, or social media apps. Every single American, presumably many who voted for Nixon's landslide victory, got the same information from three television outlets: ABC, CBS, and NBC news. Telegrams, letters, phone calls, letters to the editor in local newspapers and polls showed the country's mood had turned against Nixon, plus his promise to get us out of the Vietnam War turned out to be a boondoggle: many families were welcoming their loved ones home in body bags in a war it clearly looked like we weren't going to win. Altruism and fealty to The Constitution had nothing to do with republicans then, or now. The party talked Agnew into leaving on a lesser charge to get Gerald Ford - a congressman from Ohio, with no association to Nixon, or Agnew - in as Vice President. Then, the Republicans could keep power at the Executive Branch if an Impeachment in the House led to a conviction in the Senate, and forced removal.

 

The speed of a sprinter, a thrown fastball, the luminescence of a distant star, or the Hawking's Radiation of a Black Hole is demonstrable, measurable facts. They are not subject to opinions, "alternative facts," quackery, or spin. On the one hand, first, second, and third place is determinable. The speed of a Rookie fastball pitched from a mound can be logged; the astrophysical properties of distant objects can be studied because there is an agreement on what IS true and what is false in sports and physics.

“Science is far from a perfect instrument of knowledge. It's just the best we have. In this respect, as in many others, it's like democracy. Science by itself cannot advocate courses of human action, but it can certainly illuminate the possible consequences of alternative courses of action.”

"The scientific way of thinking is at once imaginative and disciplined. This is central to its success. Science invites us to let the facts in, even when they don’t conform to our preconceptions. It counsels us to carry alternative hypotheses in our heads and see which best fit the facts. It urges on us a delicate balance between no-holds-barred openness to new ideas, however heretical, and the most rigorous skeptical scrutiny of everything — new ideas and established wisdom. This kind of thinking is also an essential tool for a democracy in an age of change."

“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.”

The premiere of Stephen Colbert's witty and insightful show probably had a lot to do with the "truthiness" on Weapons of Mass Destruction in Iraq. That was demonstrably a lie. Yet, time and comparison to our current tweet-addicted sociopath make memories fail, as even George W. Bush now can pay respects to John Lewis: he was one of three living presidents to do so. The current occupant is too racist, devoted to his base, and fantasy to do so.

Ted Cruz is a Harvard-trained lawyer, and like President Obama, an editor of the Harvard Law Review. He's taken to Twitter to spread baseless conspiracy theories, and promote a right-wing social media app, Parler, financed by Rebecca Mercer, who like her billionaire hedge fund father, funds right-wing causes around the globe. It also shows his disdain for the people in Texas that are his constituents: he thinks they're fools, and probably wants to run for president again on the gravy train of lunacy Orange Satan built. The Republican Party genuinely fear their own base. They've stoked them every time a Democrat ascends to the presidency that the great purge of "coming to take your guns" is around the corner, any minute now. There were more guns sold during the Obama administration than the current imbecilic nightmare. I assume gun industry sales will improve apace.

The irony is, Parler is a completely enclosed silo. Part of the perverse joy of social media by sociopaths is "owning the libs," a badge of honor after frustrating arguments back and forth on a platform that you get blocked. Similar I'm sure, to throwing pollutants in the air from smokestacks on trucks, thinking oneself immune from the effects on Earth-Two. There are few "libs" on Parler to own. It also shows the tech company's regard for the intelligence of conservatives is limited, but they can see an opportunity, like most snake oil salesmen and conmen, to make a fast buck off gullible marks.

You cannot measure a sporting achievement without a knowledge of the rules, and adherence to them to make a judgment on performance.

You cannot have a STEM field without knowing the foundations of its knowledge, what is, and is not possible, and adherence to The Scientific Method to make an evaluation of the outcome of an experiment, and the world.

You cannot have a Democratic Republic with truth decay. To list them together is an oxymoron. Unless your ultimate goal is a fascist state.

(Nanowerk News) Physicists at Münster University have succeeded in fully integrating nanodiamonds into nanophotonic circuits and at the same time addressing several of these nanodiamonds optically. The study creates the basis for future applications in the field of quantum sensing schemes or quantum information processors.

The results have been published in the journal Nano Letters ("Integration of Diamond-Based Quantum Emitters with Nanophotonic Circuits").

Using modern nanotechnology, it is possible nowadays to produce structures that have feature sizes of just a few nanometers.

This world of the most minute particles – also known as quantum systems – makes possible a wide range of technological applications, in fields which include magnetic field sensing, information processing, secure communication, or ultra-precise timekeeping. The production of these microscopically small structures has progressed so far that they reach dimensions below the wavelength of light.

In this way, it is possible to break down hitherto existent boundaries in optics and utilize the quantum properties of light. In other words, nanophotonics represents a novel approach to quantum technologies.

With COVID-19 reaching the most dangerous levels the U.S. has seen since the pandemic began, the country faces a problematic holiday season. Despite the risk, many people are likely to travel using various forms of transportation that will inevitably put them in relatively close contact with others. Many transit companies have established frequent cleaning routines, but evidence suggests that airborne transmission of the novel coronavirus poses a greater danger than surfaces. The virus is thought to be spread primarily by small droplets, called aerosols, that hang in the air and larger droplets that fall to the ground within six feet or so. Although no mode of public transportation is completely safe, there are some concrete ways to reduce risk, whether on an airplane, train or bus—or even in a shared car.

At a casual glance, air travel might seem like the perfect recipe for COVID transmission: it packs dozens of people into a confined space, often for hours at a time. But many planes have excellent high-efficiency particulate air (HEPA) filters that capture more than 99 percent of particles in the air, including microbes as SARS-CoV-2, the coronavirus that causes COVID. When their recirculation systems are operating, most commercial passenger jets bring in outside air in a top-to-bottom direction about 20 to 30 times per hour. This results in a 50–50 mix of outside and recirculated air and reduces the potential for the airborne spread of a respiratory virus. Many airlines now require passengers to wear a mask during flights except for mealtimes, and some are blocking off middle seats to allow more distancing between people. Companies have also implemented rigorous cleaning procedures between flights. So how does this translate into overall risk?

“An airplane cabin is probably one of the most secure conditions you can be in,” says Sebastian Hoehl of the Institute for Medical Virology at Goethe University Frankfurt in Germany, who has co-authored two papers on COVID-19 transmission on specific flights, which were published in JAMA Network Open and the New England Journal of Medicine, respectfully. Still, a handful of case studies have found that limited transmission can take place on board. One such investigation of a 10-hour journey from London to Hanoi starting on March 1 found that 15 people were likely infected with COVID-19 in-flight—and that 12 of them had sat within a couple of rows of a single symptomatic passenger in business class. (The results were published this month in the U.S. Centers for Disease Control and Prevention’s journal Emerging Infectious Diseases.) Most of these flights occurred early on in the pandemic, however, and in the case of the March 1 flight, masks were likely not worn, the researchers wrote. Meanwhile, a recent Department of Defense study modeled the risk of in-flight infection using mannequins exhaling simulated virus particles and found that a person would have to be exposed to an infectious passenger for at least 54 hours to get an infectious dose. This finding assumes the infected passenger is wearing a surgical mask, however, and it does not account for the dangers involved in removing the mask for meals or talking or in moving about on the plane.

"The human understanding is no dry light, but receives infusion from the will and affections; whence proceed sciences which may be called 'sciences as one would.' For what a man had rather were true he more readily believes. Therefore he rejects difficult things from impatience of research; sober things, because they narrow hope; the deeper things of nature, from superstition; the light of experience, from arrogance and pride; things not commonly believed, out of the deference to the opinion of the vulgar. Numberless in short are the ways, and sometimes imperceptible, in which the affections color and infect the understanding." Sir Francis Bacon, NOVUM ORGANON (1620)

 

"A clairvoyance gap with adversary nations is announced, and the Central Intelligence Agency, under Congressional prodding, spends tax money to find out whether submarines in the ocean depths can be located by *thinking hard* at them."

The steps of the scientific method go something like this:
1. Make an observation or observations. 2. Ask questions about the observations and gather information. 3. Form a hypothesis — a tentative description of what's been observed, and make predictions based on that hypothesis. 4. Test the hypothesis and predictions in an experiment that can be reproduced. 5. Analyze the data and draw conclusions; accept or reject the hypothesis or modify the hypothesis if necessary. 6. Reproduce the experiment until there are no discrepancies between observations and theory. Source: Live Science - Science & the Scientific Method

 

Writing a physics and nano blog, one wants the audience (be they somewhat limited), to catch on to the central theme of the weblog: science, and the promotion of science literacy, for citizens of this country, and since this is the web, Earth.

 

SCIENCE IS FOR ALL STUDENTS. This principle is one of equity and excellence. Science in our schools must be for all students: All students, regardless of age, sex, cultural or ethnic background, disabilities, aspirations, or interest and motivation in science, should have the opportunity to attain high levels of scientific literacy.

 

Scientific literacy implies that a person can identify scientific issues underlying national and local decisions and express positions that are scientifically and technologically informed.

 

National Science Education Standards (1996), Chapter 2: Principles and Definitions, National Academies Press

 

This blog is a continuing, meaningful discussion about scientific and technological literacy (STL), and its importance in fostering a society of informed citizens – indeed, a prerequisite for participatory democracy – conversant in emerging fields as consumers and eventual future participant contributors. In the language of scripture, I would like to "begat" citizens versed in technology that want to research, discover, and publish in it. For a world so impacted by it, it is imperative we're all versed in it, scientists, engineers, artists, and lay citizens alike.

 

We have gone through a dizzying four-year experiment with technology and authoritarianism. No less than Foreign Affairs (Does Technology Favor Tyranny?) has studied the impact. It was fostered by a birther lie, and technology (Twitter). Though I doubt the current flailing will change election results, we have a number of citizens, in the words of Tom Nichols, who voted for the sociopath. Some of our fellow citizens "created their own realities" (Karl Rove), or delved into "alternative facts" (Kellyanne Conway). His political party could stop him, but they're too cowardly, afraid of him and his base. Sadly, these are NOT their constituents: most members of Congress are multimillionaires, worth well over the salaries we pay them. They serve, for want of a better term, American Oligarchs (Andrea Bernstein), and the businesses they give endless tax breaks to.

 

E Pluribus Unum is probably the first Latin phrase you've ever heard, or read: "out of many, one." It's the nation's motto, and poetic, but in the era of news feeds, echo chambers, and social media groups, E Pluribus Multis is more illustrative and quite apropos.

We must depart, somehow, in the next succession of days, from the false empowerment of divisive Multis, into a future fully embracing science literacy, and Unum for the survival of the species. Our baloney detection kits must be tuned to high gear.

 

“I have a foreboding of an America in my children's or grandchildren's time -- when the United States is a service and information economy; when nearly all the manufacturing industries have slipped away to other countries; when awesome technological powers are in the hands of a very few, and no one representing the public interest can even grasp the issues; when the people have lost the ability to set their own agendas or knowledgeably question those in authority; when clutching our crystals and nervously consulting our horoscopes, our critical faculties in decline, unable to distinguish between what feels good and what's true, we slide, almost without noticing, back into superstition and darkness…

 

The dumbing down of American is most evident in the slow decay of substantive content in the enormously influential media, the 30 second sound bites (now down to 10 seconds or less), lowest common denominator programming, credulous presentations on pseudoscience and superstition, but especially a kind of celebration of ignorance”

 

“We've arranged a global civilization in which most crucial elements profoundly depend on science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster. We might get away with it for a while, but sooner or later this combustible mixture of ignorance and power is going to blow up in our faces.”

We owe it to Carl's grandkids, and our children's futures, to get this right.

Clocking Dark Matter...

Clocking dark matter: optical clocks join the hunt for dark matter. (Courtesy: N Hanacek/NIST)

Topics: Dark Matter, Modern Physics, Quantum Mechanics

An optical clock has been used to set new constraints on a proposed theory of dark matter. Researchers including Jun Ye at JILA at the University of Colorado, Boulder, and Andrei Derevianko at the University of Nevada, Reno, explored how the coupling between regular matter and “ultralight” dark matter particles could be detected using the clock in conjunction with an ultra-stable optical cavity. With future upgrades to the performance of optical clocks, their approach could become an important tool in the search for dark matter.

Although it appears to account for about 85% of the matter in the universe, physicists know very little about dark matter. Most theoretical and experimental work so far has been focussed on hypothetical dark-matter particles, including WIMPS and axions, which have relatively large masses.  Alternatively, some physicists have proposed the existence of “ultralight” dark matter particles with extremely small masses that span many orders of magnitude (10−16–10−21 eV/c2).

According to the laws of quantum mechanics, the very smallest of these particles would have huge wavelengths, comparable to the sizes of entire dwarf galaxies – meaning they would behave like classical fields on scales we can easily measure.

If you ever manage to deform a diamond, you’re likely to break it. That’s because the hardest natural material on Earth is also inelastic and brittle. Two years ago, Ming Dao (MIT), Subra Suresh (Nanyang Technological University in Singapore), and their collaborators demonstrated that when bulk diamonds are etched into fine, 300-nm-wide needles, they become nearly defect-free. The transformation allows diamonds to elastically bend under the pressure of an indenter tip, as shown in the figure, and withstand extremely large tensile stresses without breaking.

The achievement prompted the researchers to investigate whether the simple process of bending could controllably and reversibly alter the electronic structure of nanocrystal diamond. Teaming up with Ju Li and graduate student Zhe Shi (both at MIT), Dao and Suresh have now followed their earlier study with numerical simulations of the reversible deformation. The team used advanced deep-learning algorithms that reveal the bandgap distributions in nanosized diamond across a range of loading conditions and crystal geometries. The new work confirms that the elastic strain can alter the material’s carbon-bonding configuration enough to close its bandgap from a normally 5.6 eV width as an electrical insulator to 0 eV as a conducting metal. That metallization occurred on the compression side of a bent diamond nanoneedle.

Note: A primer on quarks at Hyperphysics</a>

On 17 January 1957, a few months after Chien-Shiung Wu’s discovery of parity violation, Wolfgang Pauli wrote to Victor Weisskopf: “Ich glaube aber nicht, daß der Herrgott ein schwacher Linkshänder ist” (I cannot believe that God is a weak left-hander). But maximal parity violation is now well established within the Standard Model (SM). The weak interaction only couples to left-handed particles, as dramatically seen in the continuing absence of experimental evidence for right-handed neutrinos. In the same way, the polarisation of photons originating from transitions that involve weak interaction is expected to be completely left-handed.

The LHCb collaboration recently tested the handedness of photons emitted in rare flavor-changing transitions from a b-quark to an s-quark. These are mediated by the bosons of the weak interaction according to the SM – but what if new virtual particles contribute too? Their presence could be clearly signaled by a right-handed contribution to the photon polarization.

Argonne Educational Programs and Outreach transitioned to virtual summer programming, ensuring that Argonne continues to build the next generation of STEM leaders.

At the U.S. Department of Energy’s (DOE) Argonne National Laboratory, scientists and educators have found new ways to balance their work with safety needs as the laboratory’s Educational Programs and Outreach Department successfully transitioned all of its summer programming to a virtual learning environment.

By connecting scientific and research divisions across the laboratory, Argonne was able to create multiple virtual programs, helping young people stay connected and engage with the laboratory’s science, technology, engineering and math (STEM) education opportunities.

“Providing STEM opportunities and a constant presence with our next generation of STEM professions during a time that is unsettling and turbulent for everyone, but especially our school age and university student populations, was our top priority.” — Meridith Bruozas, Educational Programs, and Outreach manager

“Argonne continues to adapt and lead impactful science during the ongoing pandemic, a strategy that includes strengthening the STEM pipeline with unique educational programs for future scientists and engineers,” said Argonne Director Paul Kearns. ​“For years, hundreds of students have pursued summer learning opportunities at Argonne that are not available anywhere else. I’m pleased that in 2020 our lab community came together to maintain these high-quality STEM experiences through a successful virtual program for next-generation researchers.”

“All governments suffer a recurring problem: Power attracts pathological personalities. It is not that power corrupts but that it is magnetic to the corruptible.” Frank Herbert

 

No less than "created realities" Karl Rove and "the room where it happened," and knock off Yosemite Sam, John Bolton, have said it's time to throw in the towel. Twitter has flagged his gaslighting and will have to decide if a lame-duck lunatic is beneficial to its bottom-line. Unlike Bolton, I don't think the GOP (gang of Putin) is "coddling" him.

 

I think they completely understand their audience.

 

Mike Pompeo is a West Point Graduate and Harvard-trained lawyer. He knows the State Department is supposed to coordinate the transition, and magical thinking announced to his boss's rabid followers only delays the inevitable. He plans to run for president one day, and he's trying to "ride the dragon" the right-wing has created over 40 years. 70 million Americans are the byproducts of 40 years of hate radio, Alex Jones, dark Internet sites, and Fox propaganda. They all decided to despite evidence, in the words of Tom Nichols, vote for the sociopath. That for all intents and purposes is their "base."

 

Reagan is a paper saint: he started the birth of this dragon in Philadelphia, Mississippi, blocks from where Cheney, Goodman, and Schwerner were found. The "wink-and-nod" to white supremacy had begun. It metastasized in four decades to a racist bullhorn after the nation's first and only black president.

 

Mitch McConnell and Lindsey Graham used the pushed-on-the-bench Amy Coney Barrett to secure their positions in the Senate, where they do absolutely NOTHING, except hold on to power for mostly their rich constituents, and the poor white rubes that think they hate the demographics shift as racially as they do. They are cynically playing this game because of the close races that should not be close in Georgia for control of the Senate. The miracles of Jon Ossoff and Reverend Warnock, both poised to oust incumbent Republican senators, will cement Stacey Abrams' Fair Fight as a blueprint that should be replicated nationally, that is if the democrats want to have power going-forward. She will win the governorship in 2022. However, the House lost 10 seats, and Georgia is in a runoff that shouldn't have been this close in a pandemic where the leader of their party is woefully inept and WAY out over his skis. But competence isn't necessary for authoritarians.

 

Authoritarianism, the principle of blind submission to authority, as opposed to individual freedom of thought and action. In government, authoritarianism denotes any political system that concentrates power in the hands of a leader or a small elite that is not constitutionally responsible to the body of the people. Authoritarian leaders often exercise power arbitrarily and without regard to existing bodies of law, and they usually cannot be replaced by citizens choosing freely among various competitors in elections. The freedom to create opposition political parties or other alternative political groupings with which to compete for power with the ruling group is either limited or nonexistent in authoritarian regimes.

What Republicans should worry about is a more serious run of failure. Republican presidents — Donald Trump and George W. Bush — have now spent almost all of their last nine consecutive years below 50% approval. Add George H.W. Bush’s final year, and that makes 10 of the last 13 Republican presidential years, with the only significant exception coming in the period after the Sept. 11 attacks (we can’t know for sure, but it seems likely that George W. Bush was heading underwater by then).

 

In other words: Whether or not Republicans have a popularity problem, they certainly seem to have a governing problem, one that at this point could be symbolized by Trump’s utter inability to deal with the pandemic or by the party’s years-long attempt to dismantle the Affordable Care Act without having any alternative to offer. Of course, it is perhaps just the luck of events that dealt Republican presidents five of the last five recessions. And the Iraq War. And the coronavirus. But my suggestion to the party, if it has lost the presidency, is to spend some time trying to figure out why its presidents seem to have such a tough time in office.

 

Why Can’t Republicans Win the Popular Vote? Jonathan Bernstein, Bloomberg News

 

When you cannot win a popular vote, you probably won't want people voting. This is why I don't think we can afford to relax, even after this Herculean effort.

 

There are the runoff elections in Georgia's Senate race that will decide if Mitch McConnell maintains his majority leadership, or Chuck Schumer finally assumes it. It will decide if Joe Biden and Kamala Harris can get their agenda done, or this is a unique one-off due to the pandemic. It will decide how LONG we're suffering from the pandemic long after 45 is fighting subpoenas for his taxes, business practices, and trying to stay out of prison. I doubt his running for president in 2024. There are too many ambitious republicans that want to ride the dragon Kraken he's summoned. They don't necessarily NEED him for that, and they are hopelessly dependent (and afraid) of their base. There's an off-year election in 2021, where the Koch brothers or local citizens can decide local seats. There will be a midterm in 2022, where Kevin McCarthy is already eyeing the Speakership for himself. We don't get a break because authoritarianism and fascism will never take a break.

 

The next authoritarian will likely, not be a buffoon.
