What happens when media and politics become forms of entertainment? As our world begins to look more and more like Orwell’s 1984, Neil’s Postman’s essential guide to the modern media is more relevant than ever.

“It’s unlikely that Trump has ever read Amusing Ourselves to Death, but his ascent would not have surprised Postman.” –CNN

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

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

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

The "corrosive effects of television" Dr. Postman's polemic critiqued was [ironically], CNN, launched June 1, 1980, on a television executive's "big idea."

Movies like the Rocky Horror Picture Show and Star Wars became cult classics because as long as customers were buying tickets and popcorn, theater owners would play the show for months, and in the case of the two mentioned, each over a year. Ted Turner's "big idea" was inspired by the creation of HBO: Home Box Office. It was the single, and only cable entertainment that expanded Hollywood's earning power, as measured by Nielsen ratings. It was unique as most television stations ended their day's programming at midnight, and so did HBO, initially. Mission creep extended their air time to twenty-four hours. "Saturday Night Live" -- essentially, an improv show was crafted for night owls, as it tiptoed past that demarcation point, by design. Ted would develop a 24-hour news service of "infotainment." The Nielsen altar gods needed satisfaction and a gimmick.

I always thought infotainment was coined by actor, and filmmaker Mario Van Peeples, but its origin was as a pejorative: "soft" news, versus hard, serious news. At a joint conference in the UK for media academicians, the infotainers put on comedy skits from 1980 - 1990 in their gatherings. The madness became a method as it's obviously been copied on either of the cable news outlets that cloned themselves on Ted Turner's model. We evolved from a nation that went from President Richard Nixon winning forty-nine out of fifty states, thereby becoming the first Republican to sweep the south with his "Law and Order" shtick post-Kent State and the violence at the Democratic National Convention, to the reality that he would be impeached in the House, and likely convicted in the Senate by members of his party due to the Watergate break-ins. It was the sober digestion of information from ABC, CBS, NBC -- noncable, pre-infotainment outlets, by an "informed citizenry" regarding the culpability of a criminal president, a president that many had voted for.

Star Trek: Enterprise premiered on September 26, 2001. Due to its unfortunate timing fifteen days after 9/11, and theme of a hopeful future, as well as the former CBS president Les Moonves' stated aversion to science fiction, ended after four seasons. His helm at CBS imploded with a sex scandal thanks to #MeToo movement accountability.

"24": I've only seen two episodes, and my casual observation is Kiefer Sutherland as Jack Bauer reasonably kept audiences on edge. The show entered the national zeitgeist in 2001: In a post-Vietnam, post-9/11 world, we needed some heroes, Tom Clancy novels were the water cooler conversation rage, Sly Stallone in Rocky version 17, or Rambo; Arnold Schwarzenegger in just about anything: we were itching for some ass to kick. Dennis Haysbert introduced the idea of an African American president before Barack Obama appeared on the scene, then all of a sudden, it wasn't a good idea beyond fantasy and Nielsen ratings. The show ran from 2001 - 2010. Liz Cheney is lionized for upholding The Constitution since the January 6, 2021 insurrection, but her dad fantasized he was a character on 24, Jack Bauer maybe, or Jack Ryan from Tom Clancy novels. In our discernment between reality and fantasy, we were collectively "jacked." The intersection between information and entertainment might have impacted her dad's decisions that led to launching a 20-year war in Afghanistan, prior to which the Taliban offered Osama Bin Laden (but war makes more money than justice); lying about, or "sexing up" intelligence about weapons of mass destruction in Iraq, destabilizing that nation birthing ISIS, and the atrocities at Abu Ghraib, and Guantanamo. Lawmakers on both sides profit mightily from world instability, not world peace. But we live in reality, not a cartoon.

What South Dakota Governor Kristi Noem is doing, what Texas Governor Greg Abbot is doing, what Florida Governor Ron DeSantis is doing, what Arkansas Governor Asa Hutchinson was doing, the lamentations of Alabama Governor Kay Ivey-post her lifting mask orders and encouraging "common sense," is the multigenerational poisoning of "whiteness," where, in a self-fictitious story, every move you make works out; every conclusion is Pollyannaish with white picket fences: the "good guys" (you) always "win" at the end of a bloodless cartoon, roll credits. This alternative, fact-free non-reality isn't five-dimensional chess: it's a societal dissociative disorder. It's the aftermath of centuries of lying to one's selves and preferring the lie over the truth. Pollyannaish vision is why after 20 years and trillions of dollars, we're shocked that our efforts in Afghanistan, or Iraq didn't work, that "when they stand up, we'll stand down" was always an empty slogan. Not facing the realities of a deadly pandemic, and its to-be-announced future Greek letter variants because of "free dumb" is figuratively, and literally a "no-brainer."

Apocalypse: It's a great title to a movie, story, supervillain, or blog post. It literally means "to uncover," or "to reveal." Biblical tradition translates and assigns it to the entire last book of the sacred text. Barbara Rossing tried to reclaim the negative interpretation of doom-and-gloom from evangelicals in her 2005 book "The Rapture Exposed." She saw this interpretation as dangerous, and lending to the United States engaging in risky international actions that could lead to Mutually Assured Destruction, or totally ignore climate change as a problem that will be solved only by the Second Coming. Fatalism like this led to our actions in Afghanistan, and Iraq. Pollyannaish viewpoints like this "kick the can down the road" to the next presidential administration, trillions of dollars wasted on corruption in Kabul that could have been invested in roads, education; universal healthcare in the US. Former Secretary of State Mike Pompeo is an example of the peril of someone in power taking our continued existence for granted, and that "their side" will be the ones to survive. Not many former Secretaries of State have ever been called "doomsday clowns."

All Americans, Native Americans, African Americans, Asian Americans, Hispanic Americans, LGBTQ Americans, Women, immigrants are being affected by the anti-democratic efforts of Republican legislatures to either pick the voters they want to be counted or if elections don't quite go their way, THROW out the results! Dr. King referred to that as "interposition, and nullification." The reason Democrats pass symbolic bills in the House named for John Lewis, or the "For the People Act" is because they KNOW they will die in the Senate. The filibuster has been adjusted, carved out, flipped, manipulated for less than our ability to call ourselves a federal republic than for billionaire Oligarchs' tax cuts. Both parties are invested in the "status quo." It is ghoulish. It needs to change, our leadership needs to change, or our continuance as a country, as a human species, is in serious question.

I hope this post is a revelation, and with its act of uncovering and facing reality, we take different actions. I'm sure that was the whole intent of Dr. Neil Postman's warnings of simply cable; before social media proliferated; before phone apps were invented, before our news outlets consolidated, and morphed into self-deluding echo chambers kowtowing to Nielsen ratings, before politicians became craven liars in stark evidence of insurrection, and would rather rule over a smoldering ruin of feces than serve in an actual democracy. Our nation and the world deserve better.

Our nation and the world get better when "we the people" demand better.

More than a decade ago, the world’s most energetic laser started to unleash its blasts on tiny capsules of hydrogen isotopes, with managers promising it would soon demonstrate a route to limitless fusion energy. Now, the National Ignition Facility (NIF) has taken a major leap toward that goal. Last week, a single laser shot sparked a fusion explosion from a peppercorn-size fuel capsule that produced eight times more energy than the facility had ever achieved: 1.35 megajoules (MJ)—roughly the kinetic energy of a car traveling at 160 kilometers per hour. That was also 70% of the energy of the laser pulse that triggered it, making it tantalizingly close to “ignition”: a fusion shot producing an excess of energy.

 “After many years at 3% of ignition, this is super exciting,” says Mark Herrmann, head of the fusion program at Lawrence Livermore National Laboratory, which operates NIF.

NIF’s latest shot “proves that a small amount of energy, imploding a small amount of mass, can get fusion. It’s a wonderful result for the field,” says physicist Michael Campbell, director of the Laboratory for Laser Energetics (LLE) at the University of Rochester.

“It’s a remarkable achievement,” adds plasma physicist Steven Rose, co-director of the Centre for Inertial Fusion Studies at Imperial College London. “It’s made me feel very cheerful. … It feels like a breakthrough.”

And it is none too soon, as years of slow progress have raised questions about whether laser-powered fusion has a practical future. Now, according to LLE Chief Scientist Riccardo Betti, researchers need to ask: “What is the maximum fusion yield you can get out of NIF? That’s the real question.”

Fusion, which powers stars, forces small atomic nuclei to meld together into larger ones, releasing large amounts of energy. Extremely hard to achieve on Earth because of the heat and pressure required to join nuclei, fusion continues to attract scientific and commercial interest because it promises copious energy, with little environmental impact.

Even as a child, before he devoted his life to the search for extraterrestrial life, Frank Drake wondered whether Earth was alone in its ability to harbor life. He wasn’t the first or the only one to wonder. There’s a reason so many are fascinated by the question: Its answer helps reveal humankind’s place in the cosmos.

Drake’s musings inspired him to pursue astronomy, serving as director of the Arecibo Observatory in Puerto Rico and president of the SETI Institute — which, as the acronym suggests, is devoted to the Search for Extraterrestrial Intelligence, and exploring the possibilities of life elsewhere in the universe. Drake is perhaps most famous for his eponymous equation — an estimate of how many alien civilizations might exist in our galaxy. Presented in 1961, the equation is generally considered as the start of a new era of searches for extraterrestrial intelligence.

But decades after the invention of that famous equation, Drake has conceded that his estimates were overly conservative. Among the too-moderate assumptions was that a potentially inhabited other world must be orbiting a star — overlooking the possibility of life on rogue planets.

Sometimes called “nomads of the galaxy” or “orphan planets,” these cold, dark worlds careen through space with no home, no solar system, no sun to orbit. Long ago, they formed around a star but were flung out, abandoned by their parents. There are billions of rogue planets — astronomers estimate there could be at least one for every star — wandering the galaxy.

It may seem futile to search for life in such cold, desolate environments, but over the last two decades, astronomers have come up with a number of possible scenarios that would make life possible on a planet without a star.

NASA’s Integrated System for Autonomous and Adaptive Caretaking, or ISAAC, is advancing new technology for robots to take care of spacecraft. Researchers recently demonstrated the tech aboard the International Space Station using Astrobee, NASA’s free-flying robotic assistants.

In April 2021, Bumble, one of the free-flying Astrobee robots aboard the International Space Station, was put to the test to investigate a simulated anomaly. In the simulation, the station’s life support systems detected a high concentration of carbon dioxide. A similar situation, in reality, could be very dangerous for the seven people who are living and working aboard the microgravity laboratory.

During the test, the small, cube-shaped robot adeptly navigated the station to find the location designated as a "vent" used for cabin air circulation and used computer vision to automatically detect the foreign object blocking the vent – an "astronaut sock," represented by a printed image of a sock. Then, Bumble called for help to clear the blockage. For its next test, Bumble completed a survey of Bay 6 of the space station’s Japanese Exploration Module, building a high-resolution multi-sensor 3D map. During this journey, Bumble found itself bumping into and untangling itself from stray cables, and coping with simulated space-to-ground communication interruptions. It ultimately persevered and completed its mission objectives, with a little timely help from ground operators.

This simulated fault scenario marked the end of the first phase of testing for software designed to enable autonomous operations of a spacecraft’s operating and robotic systems. The software’s name is ISAAC – the Integrated System for Autonomous and Adaptive Caretaking.

"ISAAC is far more than just a management tool for our robotics and spacecraft systems," said Trey Smith, the project manager for ISAAC at NASA’s Ames Research Center in California's Silicon Valley. "Our long-term vision is that it can transform a spacecraft into an autonomous robotic system itself."

NASA's future Artemis missions to the Moon and beyond will take humans farther than they ever have before – and a host of robotic and mechanical systems will go with them. On the space station, much closer to home, astronauts have been able to stay full time, surpassing 20 years of continuous human presence – something that won’t be possible in deep space for some time. How can future spacecraft operate smoothly without that consistent human touch? ISAAC aims to deliver technologies to enable remote and autonomous caretaking during long periods of time when the astronauts are not aboard to perform maintenance, logistics management, and utilization tasks, as well as when communicating with ground controllers is limited or simply unavailable.

A statement by Michael Scriven & Richard Paul, presented at the 8th Annual International Conference on Critical Thinking and Education Reform, Summer 1987.

Critical thinking is the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action. In its exemplary form, it is based on universal intellectual values that transcend subject matter divisions: clarity, accuracy, precision, consistency, relevance, sound evidence, good reasons, depth, breadth, and fairness.

The Foundation For Critical Thinking: Defining Critical Thinking

Matthew Taylor Coleman, 40, is charged with two counts of foreign murder of a United States national in the slaying of his 2-year-old son and 10-month-old daughter. He is accused of shooting them with a spearfishing gun on Monday in Rosarito — a beach community 30 minutes south of Tijuana, according to the U.S. Attorney’s Office.

Coleman runs the Lovewater Surf Co., a surfing school based in Santa Barbara, and is an alumnus of Point Loma Nazarene University in San Diego, according to the company’s website.

Coleman told FBI agents he killed his children by shooting a spear into their chests, explaining that he had been “enlightened by QAnon and Illuminati conspiracy theories” and “believed he was saving the world from monsters,” according to an affidavit in support of the complaint.

Then, there was this: A fraternity brother sent me a Messenger video: "The Vaccine Itself is Dangerous! Please listen." The word vaccine was spelled with "V (o_9) cc," or an emoji. That makes it legit, right?

My response: "I’ve had the vaccine, and so has my family. I’m not magnetic, I don’t have a chip inside of me (except Sun Chip Garden Salsa). As a doctoral student, I have to take and pass EIGHT safely classes annually, specifically now centered on COVID-19 to work in my research facility. I’m not going to listen to this brother, respectfully."

His qualifier for the videographer? She was a young lady he met in passing, whom he found to be very attractive. "No sir I'm not taking anyone's word and I'm not taking anyone's vaccine, my brother from another mother. And, if your job requires it, I think they're infringing on your civil liberties. But I say this again my brother, know exactly what you have put in your body."

I pointed out he didn't know the ingredients of what he eats in a restaurant. He retorted he did, and it was a fellow frat that revealed his recipe secrets. He, of course, left out the fact that there are other restaurants ON THE PLANET he's probably patronized, and every chef in every restaurant is not going to be that forthcoming.

Me: "Do you have a stop sign or a speed limit on your street? Ever heard of 'no shirt, no shoes, no service?' How did those things NOT violate your 'civil liberties?' The only people I encounter that know nothing about civil liberties, or civics are libertarians. Fun fact: there aren’t any countries that follow libertarian philosophy. There might be a good reason why."

That was the end of it. I blocked him. I guess I'll see him at the convention (maybe).

From medical professionals being threatened by parents that somehow think "freedom" (rhymes with "free dumb") is more important than keeping their kids from being intubated or dying, to my fraternity brother accepting info from a pretty passing face, as a nation, we're bereft not only in civics but critical thinking. We're at the end of a fifty-year campaign of gaslighting that started with the 1971 Powell memo. Summarized excellently by Thom Hartmann, it's a corporate reaction to Rachel Carson's "Silent Spring," DDT, and avoiding environmental catastrophe, leading to cigarettes-not-causing-lung-cancer disinformation, continued with fossil fuel industry obfuscations on climate change since the 1970s; launched 10 years later by Ronald Reagan with his famous "government is the problem" inauguration speech, culminating in the current "American Carnage" we're all living through. We've gotten used to lying to ourselves: our nation's full history with all its brutality, mistakes, scars, and being lied to. We're all primed to likely take advice from a pretty stranger passing in a stairwell that you might want to date or a social media post that conforms and confirms your internal biases.

The abject stupidity of this moment is by design; it does not lead to a stable republic.

"One of the things taken out of the curriculum was civics," Zappa went on to explain. "Civics was a class that used to be required before you could graduate from high school. You were taught what was in the U.S. Constitution. And after all the student rebellions in the Sixties, civics was banished from the student curriculum and was replaced by something called social studies. Here we live in a country that has a fabulous constitution and all these guarantees, a contract between the citizens and the government – nobody knows what's in it. And so, if you don't know what your rights are, how can you stand up for them? And furthermore, if you don't know what's in the document, how can you care if someone is shredding it?"

A novel semiconducting material with high thermal conductivity can be integrated into high-power computer chips to cool them down and so improve their performance. The material, boron arsenide, is better at removing heat than the best thermal-management devices available today, according to the US-based researchers who developed it.

The size of computer chips has been shrinking over the years and has now reached the nanoscale, meaning that billions of transistors can be squeezed onto a single computer chip. This increased density of chips has enabled faster, more powerful computers, but it also generates localized hot spots on the chips. If this extra heat is not dealt with properly during operation, computer processors begin to overheat. This slows them down and makes them inefficient.

Defect-free boron arsenide

Researchers led by Yongjie Hu at the University of California, Los Angeles, recently developed a new thermal-management material that is much more efficient at drawing out and dissipating heat than other known metals or semiconducting materials such as diamond and silicon carbide. This new material is known as defect-free boron arsenide (BAs), and Hu and colleagues have now succeeded in interfacing it with computer chips containing wide-bandgap high-electron-mobility gallium nitride (GaN) transistors for the first time.

Using thermal transport measurements, the researchers found that processors interfaced with BAs and running at near maximum capacity had much lower hot-spot temperatures than other heat-management materials at the same transistor power density. During the experiment, the temperature of the BAs-containing devices increased from room temperature to roughly 360 K, compared to around 410 K and 440 K, respectively, for diamond and silicon carbide.

The hundreds of climate experts who compiled the mammoth new climate report released today by the U.N. Intergovernmental Panel on Climate Change (IPCC) had to work under unprecedented pandemic conditions. At vast meetings forced online, scientists wrestled with how to convey the extent of the global crisis and the urgent need to act. It was uncanny to see “the echoes of one crisis in another,” says Claudia Tebaldi, a climate scientist at Pacific Northwest National Laboratory and one of the authors of the report.

The report paints an alarming picture but emphasizes there is still time for swift action to mitigate the worst of the projected impacts of climate change. Current average warming is now estimated at 1.1°C compared to preindustrial records, a revision based on improved methods and data that adds 0.1°C to previous estimates. Under every emissions scenario explored by the report, average warming of 1.5°C—a major target of the Paris climate accord—will very likely be reached within the next 20 years.</em>

That timetable “underscores a sense of urgency for immediate and decisive action by every country, especially the major economies,” says Jane Lubchenco, deputy director for climate and the environment at the White House ​Office of Science and Technology Policy. “This is a critical decade for keeping the 1.5°C targets within reach.” And the projections mean countries should come to the United Nations Climate Change Conference, scheduled for November, with the most “aggressive, ambitious” targets possible, she says.

A team of researchers created a new method to capture ultrafast atomic motions inside the tiny switches that control the flow of current in electronic circuits. Pictured here are Aditya Sood (left) and Aaron Lindenberg (right). Courtesy: Greg Stewart/SLAC National Accelerator Laboratory

Topics: Applied Physics, Electrical Engineering, Nanotechnology, Semiconductor Technology

A new ultrafast imaging technique that captures the motion of atoms in nanoscale electronic devices has revealed the existence of a short-lived electronic state that could make it possible to develop faster and more energy-efficient computers. The imaging technique, which involves switching the devices on and off while taking snapshots of them with an electron diffraction camera, could also help researchers probe the limits of electronic switching.

“In general, we know very little about the intermediate phases materials pass through during electronic switching operations,” explains Aditya Sood, a postdoctoral researcher at the US Department of Energy’s SLAC National Accelerator Laboratory and lead author of a paper in Science about the new method. “Our technique allows for a new way to visualize this process and therefore address what is arguably one of the most important questions at the heart of computing – that is, what are the fundamental limits of electronic switches in terms of speed and energy consumption?”

Ultrafast electron diffraction camera

Sood and colleagues at SLAC, Stanford University, Hewlett Packard Labs, Pennsylvania State University, and Purdue University chose to study devices made from vanadium dioxide (VO₂) because the material is known to transition between insulating and electrically conducting states near room temperature. It thus shows promise as a switch, but the exact pathway underlying electric field-induced switching in VO₂ has long been a mystery, Sood tells Physics World.

To take snapshots of VO₂’s atomic structure, the team used periodic voltage pulses to switch an electronic device made from the material on and off. The researchers synchronized the timing of these voltage pulses with the high-energy electron pulses produced by SLAC’s ultrafast electron diffraction (UED) camera. “Each time a voltage pulse excited the sample, it was followed by an electron pulse with a delay that we could tune,” Sood explains. “By repeating this process many times and changing the delay each time, we created a stop-motion movie of the atoms moving in response to the voltage pulse.”

This is the first time that anyone has used UED, which detects tiny atomic movements in a material by scattering a high-energy beam of electrons off a sample, to observe an electronic device during operation. “We started thinking about this subject three years ago and soon realized that existing techniques were simply not fast enough,” says Aaron Lindenberg, a professor of materials science and engineering at Stanford and the study’s senior author. “So we decided to construct our own.”

After decades of exploration in nature’s smallest domains, physicists have finally found evidence that anyons exist. First predicted by theorists in the early 1980s, these particle-like objects only arise in realms confined to two dimensions, and then only under certain circumstances — like at temperatures near absolute zero and in the presence of a strong magnetic field.

Physicists are excited about anyons not only because their discovery confirms decades of theoretical work, but also for practical reasons. For example, Anyons are at the heart of an effort by Microsoft to build a working quantum computer.

This year brought two solid confirmations of the quasiparticles. The first arrived in April, in a paper featured on the cover of Science, from a group of researchers at the École Normale Supérieure in Paris. Using an approach proposed four years ago, physicists sent an electron gas through a teeny-tiny particle collider to tease out weird behaviors — especially fractional electric charges — that only arise if anyons are around. The second confirmation came in July when a group at Purdue University in Indiana used an experimental setup on an etched chip that screened out interactions that might obscure anyon behavior.

MIT physicist Frank Wilczek, who predicted and named anyons in the early 1980s, credits the first paper as the discovery but says the second lets the quasiparticles shine. “It’s gorgeous work that makes the field blossom,” he says. Anyons aren’t like ordinary elementary particles; scientists will never be able to isolate one from the system where it forms. They’re quasiparticles, which means they have measurable properties like a particle — such as a location, maybe even a mass — but they’re only observable as a result of the collective behavior of other, conventional particles. (Think of the intricate geometric shapes made by group behavior in nature, such as flocks of birds flying in formation or schools of fish swimming as one.)

The known universe contains only two varieties of elementary particles. One is the family of fermions, which includes electrons, as well as protons, neutrons, and the quarks that form them. Fermions keep to themselves: No two can exist in the same quantum state at the same time. If these particles didn’t have this property, all matter could simply collapse to a single point. It’s because of fermions that solid matter exists.

The rest of the particles in the universe are bosons, a group that includes particles like photons (the messengers of light and radiation) and gluons (which “glue” quarks together). Unlike fermions, two or more bosons can exist in the same state at the same time. They tend to clump together. It’s because of this clumping that we have lasers, which are streams of photons all occupying the same quantum state.

I read Mary Trump's book "Too Much, and Never Enough," feeling a chill when in the epilogue she predicted: "my uncle is going to get a lot of people killed." Realize, when those words were typed on presumably her laptop, she, and all of us were not wearing masks, washing hands, or standing six feet from each other in public places. Our garden-variety doomsday centered on mushroom clouds, and nuclear codes. I have preordered "Reckoning."

The fetishization of guns in America, the violence in popular entertainment, online and streaming, the rationalization of every gory and gruesome mass killing has left the public numb, and conditioned to death on a massive scale. It is no wonder we're so nonchalant about the Coronavirus: "they probably had to die of something" -- this is systemic sadism.

Governor Asa Hutchinson in Arkansas looked so nonplussed at the lectern as he tried to explain to his constituents that he had been wrong to sign an anti-mask executive order, that he was beyond just "owning the libs." With the Delta variant, and Delta plus up to bat in South Korea, conditions on the ground had decisively changed. The fact that they were shouting the latest conspiracy theories gleaned from the Internet shouldn't have surprised him: he was the source of their original gaslighting. Alabama Governor Kay Ivey admitted the unvaccinated are making the pandemic more prolonged, and worse, without a shred of guilt at her previous anti-mask stance, or irony. Leave it to Death Santis to double-down, despite falling poll numbers. His go-to stance: attack Biden, pivot to brown migrants on the border; hope for racism. He's really using that Harvard law degree.

You can't have reparations without a reckoning.

According to Jacqueline Battalora, MD, JD, in "Birth of a White Nation: The Invention of White People and Its Relevance Today," white people became an official thing in America in 1681. Dr. Gerald Horne makes similar points in his book "Race to Revolution: The U.S. and Cuba during Slavery and Jim Crow." Prior to this legislative fiat, Europeans knew each other by their home nations, in essence, their tribes. The European continent was soaked in the blood, not of Moors, but other Europeans. America organized American society as "us," and "them," the civilized, and the savages, the "correct" ethos to enslave the kidnapped, and genocide the native. It's the perfect crime that has turned a profit for a small family of the wealthy for four centuries, the "vast sucking sound," to coin a phrase from Ross Perot. All they have to do is keep us at each other's throats. We now have the pejorative “RINOs,” and “DINOs,” when an earlier descriptor labeled such politicians “moderates.” There were litmus tests of loyalty to tribes driven by cults of personality, but tribesmen didn't make laws, moderates did. It’s how things got done, or euphemistically “how the sausage got made.”

We need to teach beyond the poetry of "Manifest Destiny," that the expansion and founding of the United States were for a created class: American oligarchs. They initially just didn't want to pay taxes to their benefactor, England. Thomas Paine clarified and made the reasons to break away from Europe profound, and noble, but his progressive ideas like equal education for men, and women, a progressive income tax, welfare for the poor, and the canard that could unravel the budding dominant world economy: he opposed slavery. It's probably why you haven't heard a thing about him.

Without a reckoning, there can be no healing, no atonement, or reconciliation. Without a reckoning of January 6, there can be no justice, and the "rule of law" is meaningless. Without a reckoning, the attempted coup was practice for the next. There can be no reckoning without accurate history. Eighteen states have passed interposition, and nullification laws to keep black, indigenous people of color (BIPOC) from exercising the voting franchise, in addition to overturning elections whose outcomes they don't like. If Republicans don't want to be called fascists, they should stop acting like them.

A reckoning will enable the next reconstruction since the first one after the Civil War was interrupted by white supremacy; the second - 1964 Civil Rights Act, 1965 Voting Rights Act, 1968 Fair Housing Act - by a relentless, fifty-year right-wing backlash. History told right tends to make readers uncomfortable, but information can and should change the reader or student for the better. Showing our flaws, and blemishes should make us strive to do better, not hide our past that can easily be sourced within a few clicks, our hypocrisy laid bare.

The future is mist and mystery. It doesn't exist, except for the decisions we make today. One of those is what the fictional Vulcans of Star Trek called O'thia: reality-truth. For us to build the future, we have to reckon with our past, our real past, where we’re not always the heroes of a mythologized story we’ve gaslighted over four centuries.

Reckoning: the action or process of calculating or estimating something; the moment of truth.

Ragnarok: the final destruction of the world in the conflict between the Aesir and the powers of Hel led by Loki, the god of lies and chaos — also called Twilight of the Gods.

Without true reckoning, there is only Ragnarok.

In what could prove to be a momentous accomplishment for fundamental physics and quantum physics, scientists say they’ve finally figured out how to manufacture a scientific oddity called a time crystal.

Time crystals harness a quirk of physics in which they remain ever-changing yet dynamically stable. In other words, they don’t give off energy as they change conformation, making them an apparent violation of the natural law that all things gradually turn towards entropy and disorder.

Now, it seems like it’s possible for these things to exist, after all, Quanta Magazine reports. At least, that’s according to what a massive team of researchers from Stanford, Princeton, and elsewhere working with Google’s quantum computing labs claimed in preprint research shared online last week. Aside from being an incredible scientific discovery in abstract — time crystals represent a new, bizarre phase of matter — the discovery could have profound implications for the finicky world of quantum computing.

“The consequence is amazing: You evade the second law of thermodynamics,” study coauthor and Max Planck Institute for the Physics of Complex Systems director Roderich Moessner told Quanta.

When we gaze up at the night sky, we might be accidentally eavesdropping on an alien conversation.

At least, that’s according to Imperial College London quantum physicist Terry Rudolph, who last week published preprint research theorizing that an advanced extraterrestrial civilization might alter the light coming off stars in order to communicate across a great distance, almost like a series of interstellar smoke signals.

The physics of the ordeal gets a bit dense — which is probably reasonable if aliens are rapidly communicating across star systems — but the basic idea is to use entangled photons from different stars to transmit messages that appear to be random twinkling to any nosy onlookers.

Roaming Charges

The idea, Rudolph notes, is technically possible as far as the physics are concerned, but pure speculation when it comes to any discussion of alien technology. But as he writes in the paper, any entangled communication among stars “can be rendered in principle indiscernible to those of us excluded from the conversation.”

So if there were a mega-advanced civilization out there colonizing the Milky Way galaxy, communication along the lines of what Rudolph has proposed could explain why we haven’t found any evidence of life beyond Earth.

Your desk is made up of individual, distinct atoms, but from far away its surface appears smooth. This simple idea is at the core of all our models of the physical world. We can describe what’s happening overall without getting bogged down in the complicated interactions between every atom and electron.

So when a new theoretical state of matter was discovered whose microscopic features stubbornly persist at all scales, many physicists refused to believe in its existence.

“When I first heard about fractons, I said there’s no way this could be true because it completely defies my prejudice of how systems behave,” said Nathan Seiberg, a theoretical physicist at the Institute for Advanced Study in Princeton, New Jersey. “But I was wrong. I realized I had been living in denial.”

The theoretical possibility of fractons surprised physicists in 2011. Recently, these strange states of matter have been leading physicists toward new theoretical frameworks that could help them tackle some of the grittiest problems in fundamental physics.

Fractons are quasiparticles — particle-like entities that emerge out of complicated interactions between many elementary particles inside a material. But fractons are bizarre even compared to other exotic quasiparticles because they are totally immobile or able to move only in a limited way. There’s nothing in their environment that stops fractons from moving; rather it’s an inherent property of theirs. It means fractons’ microscopic structure influences their behavior over long distances.

“That’s totally shocking. For me it is the weirdest phase of matter,” said Xie Chen, a condensed matter theorist at the California Institute of Technology.

When it comes to making steel greener, “only the laws of physics limit our imagination,” says Christina Chang of the Advanced Research Projects Agency-Energy (ARPA–E). Chang, an ARPA–E fellow, is seeking public input on a potential new agency program titled Steel Made via Emissions-Less Technologies. During her two-year tenure, she will guide program creation, agency strategy, and outreach. Steelmaking currently accounts for about 7% of the world’s carbon dioxide emissions, and demand for steel is expected to double by 2050 as low-income countries’ economies grow, according to the International Energy Agency.

Founded in 2009, ARPA–E is a tiny, imaginative office within the Department of Energy. SMELT is one part of a three-pronged thrust by ARPA–E to green up processes involved in producing steel and nonferrous metals, from the mine through to the finished products. Another program seeks ways to make use of the vast volumes of wastes that accumulate from mining operations around the globe—and reduce the amounts generated in the future. The agency is also exploring the feasibility of deploying plants that suck up from soils elements such as cobalt, nickel, and rare earths. Despite being essential ingredients in electric vehicles, batteries, and wind turbines, the US has little or no domestic production of them. (See Physics Today, February 2021, page 20.)

Steelmaking

The first step in steelmaking is separating iron ore into oxygen and iron metal, which produces CO₂ through both the reduction process and the fossil-fuel burning necessary to create high heat. An ARPA–E solicitation for ideas to clean up that process closed on 14 June. The agency is looking to replace the centuries-old blast furnace with greener technology that can work at the scale of 2 gigatons of steel production annually. It may or may not follow up with a request for research proposals to fund.
