Small Steps, Large Changes...

10952388074?profile=RESIZE_400x

A vertical shock tube at Los Alamos National Laboratory is used for turbulence studies. Sulfur hexafluoride is injected at the top of the 5.3-meter tube and allowed to mix with air. The waste is ejected into the environment through the blue hose at the tube tower’s lower left; in the fiscal year 2021, such emissions made up some 16% of the lab’s total greenhouse gas emissions. The inset shows a snapshot of the mixing after a shock has crossed the gas interface; the darker gas is SF6, and the lighter is air. The intensities yield density values.

Reducing air travel, improving energy efficiency in infrastructure, and installing solar panels are among the obvious actions that individual researchers and their institutions can implement to reduce their carbon footprint. But they can take many other small and large steps, too, from reducing the use of single-use plastics and other consumables and turning off unused instruments to exploiting waste heat and siting computing facilities powered by renewable energy. On a systemic level, measures can encourage behaviors to reduce carbon emissions; for example, valuing in-person invited job talks and remote ones equally could lead to less air travel by scientists.

So far, the steps that scientists are taking to reduce their carbon footprint are largely grassroots, notes Hannah Johnson, a technician in the imaging group at the Princess Máxima Center for Pediatric Oncology in Utrecht and a member of Green Labs Netherlands, a volunteer organization that promotes sustainable science practices. The same goes for the time and effort they put in for the cause. One of the challenges, she says, is to get top-down support from institutions, funding agencies, and other national and international scientific bodies.

At some point, governments are likely to make laws that support climate sustainability, says Astrid Eichhorn, a professor at the University of Southern Denmark whose research is in quantum gravity and who is active on the European Federation of Academies of Sciences and Humanities committee for climate sustainability. “We are in a situation to be proactive and change in ways that do not compromise the quality of our research or our collaborations,” she says. “We should take that opportunity now and not wait for external regulations.”

Suppose humanity manages to limit emissions worldwide to 300 gigatons of carbon dioxide equivalent (CO2e). In that case, there is an 83% chance of not exceeding the 1.5 °C temperature rise above preindustrial levels set in the 2015 Paris Agreement, according to a 2021 Intergovernmental Panel on Climate Change special report. That emissions cap translates to a budget of 1.2 tons of CO2e per person annually through 2050. Estimates for the average emissions by researchers across scientific fields are much higher and range widely in part because of differing and incomplete accounting approaches, says Eichhorn. She cites values from 7 to 18 tons a year for European scientists.

Reimagining ET...

Sarah Stewart Johnson was a college sophomore when she first stood atop Hawaii’s Mauna Kea volcano. Its dried lava surface differed from the eroded, tree-draped mountains of her home state of Kentucky. Johnson wandered away from the other young researchers she was with and toward a distant ridge of the 13,800-foot summit. Looking down, she turned over a rock with the toe of her boot. To her surprise, a tiny fern lived underneath it, sprouting from ash and cinder cones. “It felt like it stood for all of us, huddled under that rock, existing against the odds,” Johnson says.

Her true epiphany, though, wasn’t about the hardiness of life on Earth or the hardships of being human: It was about aliens. Even if a landscape seemed strange and harsh from a human perspective, other kinds of life might find it quite comfortable. The thought opened up the cosmic real estate and the variety of life she imagined might be beyond Earth’s atmosphere. “It was on that trip that the idea of looking for life in the universe began to make sense to me,” Johnson says.

Later, Johnson became a professional at looking. As an astronomy postdoc at Harvard University in the late 2000s and early 2010s, she investigated how astronomers might use genetic sequencing—detecting and identifying DNA and RNA—to find evidence of aliens. Johnson found the work exciting (the future alien genome project!), but it also made her wonder: What if extraterrestrial life didn’t have DNA, RNA, or other nucleic acids? What if their cells got instructions in some other biochemical way?

As an outlet for heretical thoughts like this, Johnson started writing in style too lyrical and philosophical for scientific journals. Her typed musings would later turn into the 2020 popular science book The Sirens of Mars. Inside its pages, she probed the idea that other planets were truly other. So their inhabitants might be very different, at a fundamental and chemical level, from anything in this world. “Even places that seem familiar—like Mars, a place that we think we know intimately—can completely throw us for a loop,” she says. “What if that’s the life case?”

Climate change is already disrupting the lives of billions of people. What was once considered a problem for the future is raging all around us right now. This reality has helped convince a majority of the public that we must act to limit suffering. In an August 2022 survey by the Pew Research Center, 71 percent of Americans said they had experienced at least one heat wave, flood, drought, or wildfire in the past year. Among those people, more than 80 percent said climate change had contributed. In another 2022 poll, 77 percent of Americans who said they had been affected by extreme weather in the past five years saw climate change as a major crisis.

Yet the response is not meeting the urgency of the crisis. A transition to clean energy is underway, but it is happening too slowly to avoid the worst effects of climate change. The U.S. government finally took long-delayed action by passing the Inflation Reduction Act in August 2022, much more progress is needed, and entrenched politics hamper it. The partisan divide largely stems from conservatives’ perception that climate change solutions will involve big government controlling people’s choices and imposing sacrifices. Research shows that Republicans’ skepticism about climate change is largely attributable to a conflict between ideological values and often-discussed solutions, particularly government regulations. A 2019 study on Climatic Change found that political and ideological polarization on climate change is particularly acute in the U.S. and other English-speaking countries.

One thing we can all do to ease this gridlock is to alter the language and messages we use about climate change. The words we use and the stories we tell matter. Transforming the way we talk about climate change can engage people and build the political will needed to implement policies strong enough to confront the crisis with the urgency required.

To inspire people, we need to tell a story not of sacrifice and deprivation but of opportunity and improvement in our lives, health, and well-being—a story of humans flourishing in a post-fossil-fuel age.

The New McCarthyism...

Debt Ceiling and Dystopia

The debt limit does not authorize new spending commitments. It simply allows the government to finance existing legal obligations that Congresses and presidents of both parties have made in the past.

Failing to increase the debt limit would have catastrophic economic consequences. It would cause the government to default on its legal obligations – an unprecedented event in American history. That would precipitate another financial crisis and threaten the jobs and savings of everyday Americans – putting the United States right back in a deep economic hole just as the country is recovering from the recent recession.

Congress has always acted when called upon to raise the debt limit. Since 1960, Congress has acted 78 separate times to permanently raise, temporarily extend, or revise the definition of the debt limit – 49 times under Republican presidents and 29 times under Democratic presidents. Congressional leaders in both parties have recognized that this is necessary.

The Old McCarthyism

Elected to the Senate in 1946, Joseph McCarthy (1908-1957) did not draw major national attention until 1950. On February 9th of that year, he delivered a Lincoln Day address in Wheeling, West Virginia, blaming failures in American foreign policy on Communist infiltration of the U.S. government. The Wisconsin Republican claimed to have a list of known Communists still working in the Department of State. A special subcommittee investigated McCarthy’s charges and rejected them as “a fraud and a hoax.” Still, the outbreak of the Korean War and the highly publicized conviction of Alger Hiss lent credibility to the charges. When McCarthy became chairman of the Permanent Subcommittee on Investigations in 1953, he launched a series of investigations into alleged subversion and espionage. In 1954 a confrontation with the army led to the nationally televised Army-McCarthy hearings, which tarnished McCarthy’s public image, undermined his charges, and prompted his censure by the U.S. Senate.

The New McCarthyism, or the New Testament of the Soulless

“If you tell a lie big enough and keep repeating it, people will eventually come to believe it. The lie can be maintained only for such time as the State can shield the people from the political, economic, and/or military consequences of the lie. It thus becomes vitally important for the State to use all of its powers to repress dissent, for the truth is the mortal enemy of the lie, and thus by extension, the truth is the greatest enemy of the State.

This is an excellent definition of the “Big lie,” however, there seems to be no evidence that it was used by Nazi propaganda chief Joseph Goebbels, though it is often attributed to him.

The OSS psychological profile of Hitler described his use of the big lie:

His primary rules were: never allow the public to cool off; never admit a fault or wrong; never concede that there may be some good in your enemy; never leave room for alternatives; never accept blame; concentrate on one enemy at a time and blame him for everything that goes wrong; people will believe a big lie sooner than a little one; and if you repeat it frequently enough people will sooner or later believe it.

Source: Jewish Virtual Library/Joseph Goebbels: The Big Lie

"Then if anyone at all is to have the privilege of lying, the rulers of the State should be the persons; and they, in their dealings either with enemies or with their [own] citizens, may be allowed to lie for the public good. But nobody else should meddle with anything of the kind." Plato, The Republic

We tell ourselves lies: E Pluribus Unum - out of many, one, or the "melting pot," Emma Lazarus's poem at the Statue of Liberty, whitewashing the kidnapping of Africans, the indentured servitude of poor whites and Native Americans, the disdain our immigration laws treated immigrants from the Chinese Exclusion Act, Catholics, Italians, Czecholovacians, Russians, to the recently attempted Muslim Ban.

One lie a sizable number of citizens are telling themselves: a demographic shift either isn't happening or can be mitigated by either denying electoral losses or keeping certain people from voting.

America Looks Different

The nation’s demographic changes add to the urgency of recognizing how precarious our position has become.

America is changing demographically, and unless Republicans can grow our appeal the way GOP governors have done, the changes tilt the playing field even more in the Democratic direction.

In 1980, exit polls tell us that the electorate was 88 percent white. In 2012, it was 72 percent white. Hispanics made up 7 percent of the electorate in 2000, 8 percent in 2004, 9 percent in 2008, and 10 percent in 2012. According to the Pew Hispanic Center, in 2050, whites will be 47 percent of the country, while Hispanics will grow to 29 percent and Asians to 9 percent.

If we want ethnic minority voters to support Republicans, we must engage them and show our sincerity.

Source: The Growth and Opportunity Project (the so-called autopsy), page 7, paragraph 2

A functional party would look at this and disseminate it. They might hire consultants to form focus groups. The message would be broadcast from radio stations, television, and the Internet: Republicans want to be a "big tent" party. We (republicans) want to expand to minorities, women, and youth. A function party acting on these practical, fact-based conclusions would look completely different than the fiasco we are currently witnessing. They have shown since this report to be racing in the opposite direction, heading over the proverbial lemming cliff. Maybe they tried, but most of their electorate wasn't receptive to "others" being under their red tent.

Rural Americans reliably votes republican and guaranteed the re-elections of Greg Abbott and Ron DeSantis, miniatures of Trump showing after higher infection rates and deaths from Covid, gun massacres, faux crusades against asylum seekers, undocumented immigrants - usually coming for construction jobs at American companies paying them cash under the table, and wars against Critical Race Theory (i.e., accurately taught American history), Nazi book bans, and assaulting the beach of Drag Queen story hour with AR15s - all it takes to win elections is the scare and make angry the right number of white people.

The New McCarthyism is based on Goebbels's "Big Lie," the current one given by a septuagenarian that could not accept another septuagenarian who beat him in the 2020 election. So narcissistic and pathological was the loser he fomented a coup in the 21st Century, 20 years after 9-11. Osama Bin Laden is gone, a casualty of Seal Team Six, but his chief aim of destabilizing the west of showing the "Great Satan" to be a paper tiger. To show that the ideals we espoused overseas couldn't even be maintained at home. The Civil Rights Movement, the killing of African Americans: all of this has been televised and broadcast. Osama and Vladimir Putin only pushed on an open sore and poured in salt. The culmination of Osama and Vladimir's wildest dreams was the election of a mop-headed, fake billionaire that has lost more money than he's ever earned. The book I believe he read from cover to cover and emulated in his rallies was "My New Order," a collection of speeches by Adolf Hitler. It is in its original form, 1,008 pages long. At one time, he had an attention span beyond that of a gnat. He seems to have committed it to memory. The only person who would know for sure, Ivana, is buried surreptitiously on his golf course in New Jersey.

Concealed carry devolved to open carry, in many states requiring no registration or training, studies showing the threats to African Americans getting shot elevated by such conditions. The goal of the New McCarthyism is the same as old-time American Klan-robed fascism: it frightens African Americans first, then the general public. Where does anyone feel safe now when schools, malls, and places of worship have become killing fields? The government dysfunction we’ve seen since the Speaker vote debacle and the threat not to raise the debt ceiling (25% of which was accrued during the previous administration) is by design. It is to “wear out” the electorate; it is the proverbial “pox on both houses,” and the convenient discovery of classified documents with former Vice Presidents Biden and Pence is both sides-ism on steroids and textbook gaslighting. It is to give us no reason to believe voting will change anything. It is voter suppression by gaslighting because the Growth and Opportunity Project would take too much work. and change. They are not a serious governing party: they are the comments section on Facebook reading "Green Eggs and Ham."

The Republic is a repudiation of the rights of kings to rule over a country, the lives of peasants, and hoard wealth for themselves. The new world kings/billionaires/oligarchs are trying to reestablish that through means of fear, violence, and terror.

Kevin McCarthy will cement his legacy as this nation's weakest (and likely, short-lived) Speaker of the House. He's given away his power and threatened the default of the full faith and credit of the United States. This would defund the Ukraine war on Ukraine's and Russia's sides. It would raise U.S. unemployment from record lows to third-world levels. It would pitch the world over that same lemming's cliff into the Greatest Depression, possibly the last. It would guarantee an electoral loss for the Grand Old Party that rejected the price of growth and opportunity: diversity, equity, and inclusion.

Currently authorized bivalent COVID-19 boosters demonstrated similar protection against symptomatic illness from the XBB/XBB.1.5 Omicron subvariants as from BA.5-related subvariants, according to a CDC study.

From December 2022 to January 2023, the bivalent boosters' vaccine effectiveness (VE) against symptomatic infection was a similar 48% versus XBB/XBB.1.5-related strains and 52% versus BA.5-related sublineages, reported Ruth Link-Gelles, Ph.D., of the CDC's National Center for Immunization and Respiratory Diseases, and colleagues in Morbidity and Mortality Weekly Report (MMWR).

Meanwhile, Pfizer's updated booster demonstrated superior neutralizing antibody activity compared with the company's original product against all the latest Omicron subvariants, including XBB.1, according to Kena Swanson, Ph.D., of Pfizer Vaccine Research and Development in Pearl River, New York and colleagues, writing in the New England Journal of Medicine. Their findings contradict earlier research from other labs that found no significant difference in neutralizing activity with the bivalent over the monovalent vaccine.

According to the latest estimates from the CDC, XBB.1.5 is responsible for 49.1% of new COVID-19 cases in the U.S., while XBB is responsible for another 3.3%.

When Water Outpaces Silicon…

A laser-controlled water-based switch that operates twice as fast as existing semiconductor switches has been developed by a trio of physicists in Germany. Adrian Buchmann, Claudius Hoberg, and Fabio Novelli at Ruhr University Bochum used an ultrashort laser pulse to create a temporary metal-like state in a jet of liquid water. This altered the transmission of terahertz pulses over timescales of just tens of femtoseconds.

With the latest semiconductor-based switches approaching fundamental upper limits on how fast they can operate, researchers are searching for faster ways of switching signals. One unexpected place to look for inspiration is the curious behavior of water under extreme conditions – like those deep within ice-giant planets or created by powerful lasers.

Molecular dynamics simulations suggest water enters a metallic state at pressures of 300 GPa and temperatures of 7000 K. While such conditions do not occur on Earth, it is possible that this state contributes to the magnetic fields of Uranus and Neptune. To study this effect closer to home, recent experiments have used powerful, ultrashort laser pulses to trigger photo-ionization in water-based solutions – creating fleeting, metal-like states.

Abstract

The magnetic response of most natural materials, characterized by magnetic permeability, is generally weak. Particularly in the optical range, the weakness of magnetic effects is directly related to the asymmetry between electric and magnetic charges. Harnessing artificial magnetism started with a pursuit of metamaterial design exhibiting magnetic properties. A plasmonic nanostructure called split-ring resonators gave the first demonstration of artificial magnetism. Engineered circulating currents form magnetic plasmons, acting as the source of artificial magnetism in response to external electromagnetic excitation. In the past two decades, magnetic plasmons supported by plasmonic nanostructures have become an active topic of study. This Perspective reviews the latest studies on magnetic plasmons in plasmonic nanostructures. A comprehensive summary of various plasmonic nanostructures supporting magnetic plasmons, including split-ring resonators, metal–insulator–metal structures, metallic deep groove arrays, and plasmonic nanoclusters, is presented. Fundamental studies and applications based on magnetic plasmons are discussed. The formidable challenges and the prospects of the future study directions on developing magnetic plasmonic nanostructures are proposed.

Scientists have advanced in discovering how to use ripples in space-time known as gravitational waves to peer back to the beginning of everything we know. The researchers say they can better understand the state of the cosmos shortly after the Big Bang by learning how these ripples in the fabric of the universe flow through planets and the gas between the galaxies.

"We can't see the early universe directly, but maybe we can see it indirectly if we look at how gravitational waves from that time have affected matter and radiation that we can observe today," said Deepen Garg, lead author of a paper reporting the results in the Journal of Cosmology and Astroparticle Physics. Garg is a graduate student in the Princeton Program in Plasma Physics, which is based at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL).

Garg and his advisor Ilya Dodin, who is affiliated with both Princeton University and PPPL, adapted this technique from their research into fusion energy, the process powering the sun and stars that scientists are developing to create electricity on Earth without emitting greenhouse gases or producing long-lived radioactive waste. Fusion scientists calculate how electromagnetic waves move through plasma, the soup of electrons and atomic nuclei that fuels fusion facilities known as tokamaks and stellarators.

The modern martial arts belt ranking system first started emerging in 1907 when the creator of Judo, Jigoro Kano, introduced the iconic Judo uniform and belt. Before that, his students practiced traditional Japanese kimonos. However, back then, there existed only two belt colors: white and black. White belts were those in the process of learning the fundamentals, while black belts were students who mastered the basics, knew how to use them functionally, and were ready to pursue Judo on a more serious and advanced level. The white coloring represented purity, avoidance of ego, and simplicity, while the black symbolized a fuller repertoire of knowledge.

A popular belief within the martial arts community is that every student started off with a white belt, then gradually, it darkened in color from all the blood, sweat, and tears of training. However, there exists no real historical evidence of this practice, and it is generally regarded to be little more than a myth. Source: https://stouttrainpitt.com/

Hierarchy (noun): a system in which people or things are arranged according to their importance. Cambridge Dictionary

Every nation has an arrangement of those who are deemed "important." In the United Kingdom, since Charles ascended after the death of his mother, Elizabeth, they are apparently the beneficiaries of the Norman invasion in 1066, which deposed someone named Harald Godwinson and the House of Wessex. After several centuries of colonization, plunder, and slavery, the "Commonwealth" was born, and the fairytale of Camelot was used to justify plunder. One hierarchy is justified with belt colors, the other with propaganda.

In November 2022, we reached eight billion with something of a shrug. We were 4.4 billion my senior year in high school, 1979 - 1980.

The average human takes up an area of approximately one square meter.

The volume of Earth is about 1,000 billion cubic kilometers, per the World Bank.

4,400,000,000,000/1,000,000,000,000,000,000,000 = 4.4E-12

8,000,000,000,000/1,000,000,000,000,000,000,000 = 8.0E-12

Relax. These surface-to-volume ratios only work on the nanoscale. For example, if we were a metal, say gold, the spectrographic analysis would show that due to the S/V ratio being different, the color of a macroscopic (seen) bar of gold would be different on the nanoscale (in many cases, blue or other colors) because the S/Vs are different.

It is a gross and stark illustration that as we exponentially increase in population, we're exponentially decreasing the ability to feed our population. The fraction's denominator did not change, but you can bet feeding the first humans in Africa was a lot simpler math than eight billion. The first thing learned in kindergartens for the 99% is to share. One presumes the first thing learned in nurseries for plutocrats is how to hoard.

Therefore, the castes of royalty, race, and inequality justify hoarding resources in a siphon-up operation (the antonym of "trickledown"). Billionaires, like kings, influence through propaganda the justification of resource theft. To ensure the running of this machine, you need some willing advocates (e.g., Kyrsten Sinema, Boris Johnson, Joe Manchin, Rishi Sunak) in world governments such that the obscenely wealthy will pay little or nothing in taxes in their respective countries. Camouflage the theft with drivel like "free markets" or "God's will." Having a compliant court system to define "money as free speech" helps magnify your megaphone and hides where and from what country your campaign donations are coming [from]. Social media, with the protection of Section 230, can proverbially "shout fire in crowded theaters" without consequences, except the empty "we'll do better" promises. They pay for Members of Parliament, Senators, House Members, and presidents to enact their agendas, despite their nation's constitutions. Democracy is, thus, anathema to avarice.

We have a global hierarchal social construct. Instead of the distribution of resources that ensures the health, safety, and welfare of the human tribe, a justification is given to those more "worthy" of the resources: bloodlines, divine right, "good genes" (eugenics), going to the "right" schools, being born on the "right" side of the tracks, "talented tenths"; secret fraternal orders, and open orgies of oligarch opulence like Davos. It is the justification of high crimes and misdemeanors committed in plain sight. It is the framework of how we justify the "haves" and the "have-nots." It is a form of societal cognitive dissonance. It has justified the grand theft of natural resources, political power, and, thus, wealth over millennia. It has no analog in nature and does not guarantee species survival.

The dinosaurs did not perish from arrogance. They [simply] had no science to tell them that the meteor was coming.

As space missions delve deeper into the outer solar system, the need for more compact, resource-conserving, and accurate analytical tools have become increasingly critical—especially as the hunt for extraterrestrial life and habitable planets or moons continues.

A University of Maryland–led team developed a new instrument specifically tailored to the needs of NASA space missions. Their mini laser-sourced analyzer is significantly smaller and more resource efficient than its predecessors—all without compromising the quality of its ability to analyze planetary material samples and potential biological activity onsite. The team's paper on this new device was published in the journal Nature Astronomy on January 16, 2023.

Weighing only about 17 pounds, the instrument is a physically scaled-down combination of two important tools for detecting signs of life and identifying compositions of materials: a pulsed ultraviolet laser that removes small amounts of material from a planetary sample and an Orbitrap analyzer that delivers high-resolution data about the chemistry of the examined materials.

"The Orbitrap was originally built for commercial use," explained Ricardo Arevalo, lead author of the paper and an associate professor of geology at UMD. "You can find them in the labs of pharmaceutical, medical and proteomic industries. The one in my own lab is just under 400 pounds, so they're quite large, and it took us eight years to make a prototype that could be used efficiently in space—significantly smaller and less resource-intensive but still capable of cutting-edge science."

The team's new gadget shrinks down the original Orbitrap while pairing it with laser desorption mass spectrometry (LDMS)—techniques that have yet to be applied in an extraterrestrial planetary environment. The new device boasts the same benefits as its larger predecessors but is streamlined for space exploration and onsite planetary material analysis, according to Arevalo.

Graphullerene, an atom-thin material made of linked fullerene subunits, gives scientists a new form of modular carbon to play with.

Carbon, in its myriad forms, has long captivated the scientific community. Besides being the primary component of all organic life on earth, material forms of carbon have earned their fair share of breakthroughs. In 1996, the Nobel Prize in Chemistry went to the discoverers of fullerene, a superatomic symmetrical structure of 60 carbon atoms shaped like a soccer ball; in 2010, researchers working with an ultra-strong, atom-thin version of carbon, known as graphene, won the Nobel Prize in Physics.

Today in work published in Nature, researchers led by Columbia chemists Xavier Roy, Colin Nuckolls, and Michael Steigerwald, with postdoc and first author Elena Meirzadeh have discovered a new version of carbon that sits somewhere in between fullerene and graphene: graphullerene. It’s a new two-dimensional form of carbon made up of layers of linked fullerenes peeled into ultrathin flakes from a larger graphullerite crystal—just like how graphene is peeled from graphite crystals (the same material found in pencils).

“It is amazing to find a new form of carbon,” said Nuckolls. “It also makes you realize that there is a whole family of materials that can be made in a similar way that will have new and unusual properties as a consequence of the information written into the superatomic building blocks.”

Massive subsidies to regain the edge of the US semiconductor industry will not likely succeed unless progress is made in winning the global race of idea flow and monetization.

Topics: Applied Physics, Chemistry, Computer Science, Electrical Engineering, Semiconductor Technology

Intelligent use of subsidies for winning the global idea race is a must for gaining and regaining semiconductor edge.

The US semiconductor industry started with the invention of Bell Labs. Subsequently, it attained supremacy in semiconductor production due to the success of making computers better and cheaper. Notably, the rise of the PC wave made Intel and Silicon Valley seemingly unsinkable technology superpowers. But during the first two decades of the 21st century, America has lost it. The USA now relies on Asia to import the most advanced chips. Its iconic Intel is now a couple of technology generation behind Asia’s TSMC and Samsung.

Furthermore, China’s aggressive move has added momentum to America’s despair, triggering a chip war. But why has America lost the edge? Why does it rely on TSMC and Samsung to supply the most advanced chips to power iPhones, Data centers, and Weapons? Is it due to Asian Governments’ subsidies? Or is it due to America’s failure to understand dynamics, make prudent decisions and manage technology and innovation?

Invention and rise and fall of US semiconductor supremacy

In 1947, Bell Labs of the USA invented a semiconductor device—the Transistor. Although American companies developed prototypes of Transistor radios and other consumer electronic products, they did not immediately pursue them. But American firms were very fast in using the Transistor to reinvent computers—by changing the vacuum tube technology core. Due to weight advantage, US Airforce and NASA found transistors suitable for onboard computers. Besides, the invention of integrated circuits by Fairchild and Texas instruments accelerated the weight and size reduction of digital logic circuits. Consequentially, the use of semiconductors in building onboard computers kept exponentially growing. Hence, by the end of the 1960s, the US had become a powerhouse in logic circuit semiconductors. But America remained 2nd to Japan in global production, as Japanese companies were winning the race of consumer electronics by using transistors.

"If you want to say that I was a drum major, say that I was a drum major for justice. Say that I was a drum major for peace. I was a drum major for righteousness." Dr. Martin Luther King, Jr.

I am part of a generation that, when we pass, will have the last memories of hearing your voice on the radio, on television, and not be a documentary or a YouTube embed. Small children, that terrible day when we...lost you.

I remember when after the assassination of Martin Luther King, a pickup truck with a confederate flag flying behind it rode past my kindergarten, shouting epithets and gloating at his death (1968).

I saw my first burning cross at the age of fourteen (1976) during my first overnight encampment with JROTC.

This wasn’t that long ago.

Like your support of the idea of us in the future in Star Trek, we tried to embody that hope in every class we tackled, every Calculus, Physics, and Engineering problem we solved: we strove to make you proud of us, despite the fact you were here and then gone so soon.

Happy birthday sir, and THANK YOU!

"At the end of Star Trek's first season, Nichelle was thinking seriously of leaving the show, but a chance and moving meeting with Martin Luther King changed her mind. He told her she couldn't give up...she was a vital role model for young black women in America. Needless to say, Nichelle stayed with the show and has appeared in the first six Star Trek movies. She also provided the voice for Lt. Uhura on the Star Trek animated series in 1974-75."

Munchausen by Congress...

Research Gate dot net: Epidemiology of Munchausen syndrome by proxy in New Zealand

Topics: Civics, Civil Rights, Civilization, Democracy, Existentialism, Fascism, Human Rights

Tina Depuy (from her website: tee-nuh doo-pwee) wrote an analysis of the Republican Party when the House of Representatives was under John "weed head" Bohner in 2013:

Munchausen Syndrome by Proxy, now referred to as Factious Disorder by Proxy or FDbP, is where a parent or caretaker enjoys the attention of having a sick child. Hence, they exaggerate and sometimes induce their victim’s symptoms. Children are made to be sick; parents are given sympathy for their seeming stoicism. It’s adulation-seeking via child abuse.

In this case, the caretaker is Congress (specifically the Republican-controlled House). The thing they’re enjoying making unwell is, well, us: the country, our economy, postal services, meat inspections, air traffic control, infrastructure, law enforcement, military, credit rating, commerce, and every other part of a country [thought] of around the globe as a superpower.

This disorder can sometimes be traced to an early legit emergency, where the caregiver with FDbP first experiences the rush of admiration they’ll later crave. For the GOP, it’s probably September 11, 2001. It was on that day the then-leader of the Republican party (the same dude the GOP no longer acknowledges exists, they’ll even listen to Mitt Romney speak before uttering his name) finally got to do everything he wanted without question – all with an over (and brief) 80 percent approval rating. He pre-emptively invaded Iraq without paying for it, flattened wages, made the rich richer, and transformed higher education into a profit-driven industry. More importantly, he got Democrats to shut up while he pretended drunken-sailor-spending was compassionate conservatism.

Congress has Munchausen by Proxy, Tina Depuy, March 2, 2013, Post Independent.

The above article and its analysis by analog have aged incredibly well.

Unless you've been living under a rock, we now have the weakest Speaker of the House in the history of the republic who "gave away the store" to MAGA extremists and got his authority weakened. Is George Santos’s real name even George Santos? The only reason the pathological liar is tolerated is that it gives Kev a four-vote thin margin. If he removes him, it triggers a special election in a Blue State in a Democratic-leaning district (that somehow woke up from their drunken stupor and is pissed George is their Representative). If he were to survive the primary, the fictional Klingons have a proverb: "revenge is a dish that is best served cold." That would cut Kev down to three and resorting to public self-immolation. The constituents would send another Democrat to the House, increasing Hakeem Jeffries' numbers and steps toward Speaker in 2024. Under "Kev the Spinless," we can look forward to nothing but show trials, no credible laws proposed that could [possibly] pass the Senate, and going over the debt ceiling cliff in September, if Kev makes it that long.

Newton Gingrich started this mess. His philosophy was playing a zero-sum game, political terrorism, and nihilism. It was always a "Contract ON America," never WITH America, as it ignored a sizeable and growing part of the electorate that demographically, the republicans let themselves get caught flatfooted in the 21st Century, so: voter suppression as a Hail Mary. It was under Gingrich we started seeing the debt ceiling being used as a tool for hostage-taking (the entire government). He somehow (creepily) married his high school Geometry teacher, divorced her for his first mistress, then divorced the second wife (the previously-mentioned first mistress) for his second mistress (and now third wife) Calista WHILE trying to impeach Bill Clinton for the same thing!

Gingrich attempted a soft coup by Constitution: he aimed to impeach Bill Clinton and Al Gore and, by default, become President of the United States. He was both hypocritical and shameless, just like the Republican Party now. Zero-sum became the Tea Party under the first (and only) African American president, then the Orwellian "Freedom Caucus," which led inexorably to MAGA, having the same characteristics and number of letters as "Nazi." After midterm losses, he stepped down as Speaker in the face of full rebellion. Bob Livingston challenged him, then had the same "strayed from his marriage" issues as Gingrich and Clinton. That led to wrestling coach pedophile Dennis "the groomer" Hastert before Nancy Pelosi's first run. After that, John Boehner (ran out by the Tea Party), Paul Ryan (Ibid), and Nancy Pelosi for her last go-around, followed by a slimy, whimpering, limp surfer tan in a suit. Newt posing now as a wisened, sage political philosopher, is gaslighting from a windbag.

Do soft coups then become dry run practice coups like storming the Michigan Capitol under Gretchen Whitmore's first term as governor? Her attempted kidnapping and threats to her administration flukes? I guess Charlottesville, August 11 - 12, 2017, and The Insurrection of January 6, 2021, were all Antifa (antifascists) dressed as conservatives and bringing with them the Grand Pooh-Bah of the Loyal Order of Water Buffalos?

"The Republican Party is the party for normal Americans." Newt Gingrich.

Unlike Depuy's analysis, this didn't age well.

Spooky Action Between Friends...

Reference: Albert Einstein colorfully dismissed quantum entanglement—the ability of separated objects to share a condition or state—as “spooky action at a distance.” Science.org

For the first time, scientists have observed quantum interference—a wavelike interaction between particles related to the weird quantum phenomenon of entanglement—occurring between two different kinds of particles. The discovery could help physicists understand what goes on inside an atomic nucleus.

Particles act as both particles and waves. And interference is the ability of one particle’s wavelike action to diminish or amplify the action of other quantum particles like two boat wakes crossing in a lake. Sometimes the overlapping waves add up to a bigger wave, and sometimes they cancel out, erasing it. This interference occurs because of entanglement, one of the weirder aspects of quantum physics, which was predicted in the 1930s and has been experimentally observed since the 1970s. When entangled, the quantum states of multiple particles are linked so that measurements of one will correlate with measurements of the others, even if one is on Jupiter and another is on your front lawn.

Dissimilar particles can sometimes become entangled, but until now, these [mismatched] entangled particles weren’t known to interfere with one another. That’s because part of measuring interference relies on two wavelike particles being indistinguishable from each other. Imagine two photons, or particles of light, from two separate sources. If you were to detect these photons, there would be no way to determine which source each came from because there is no way to tell which photon is which. Thanks to the quantum laws governing these very small particles, this ambiguity is actually measurable: all the possible histories of the two identical photons interfere with one another, creating new patterns in particles’ final wavelike actions.

Ammonia (NH3), the chemical compound made of nitrogen and hydrogen, currently has many valuable uses, for instance, serving as a crop fertilizer, purifying agent, and refrigerant gas. In recent years, scientists have been exploring its potential as an energy carrier to reduce global carbon emissions and help tackle global warming.

Ammonia is produced via the Haber-Bosch process, a carbon-producing industrial chemical reaction that converts nitrogen and hydrogen into NH3. As this process is known to contribute heavily to global carbon emissions, electrifying ammonia synthesis would benefit our planet.

One of the most promising strategies for electrically synthesizing ammonia at ambient conditions is using lithium metal. However, some aspects of these processes, including the properties and role of lithium's passivation layer, known as the solid electrolyte interphase (SEI), remain poorly understood.

Researchers at the Massachusetts Institute of Technology (MIT), the University of California- Los Angeles (UCLA), and the California Institute of Technology have recently conducted a study closely examining the reactivity of lithium and its SEI, as this could enhance lithium-based pathways to electrically synthesize ammonia. Their observations, published in Nature Energy, were collected using a state-of-the-art imaging method known as cryogenic transmission electron microscopy.

The Decline of Disruptive Science…

The number of science and technology research papers published has skyrocketed over the past few decades — but the ‘disruptiveness’ of those papers has dropped, according to an analysis of how radically papers depart from the previous literature1.

Data from millions of manuscripts show that, compared with the mid-twentieth century, research done in the 2000s was much more likely to incrementally push science forward than to veer off in a new direction and render previous work obsolete. Analysis of patents from 1976 to 2010 showed the same trend.

“The data suggest something is changing,” says Russell Funk, a sociologist at the University of Minnesota in Minneapolis and a co-author of the analysis published on 4 January in Nature. “You don’t have quite the same intensity of breakthrough discoveries you once had.”

Telltale citations

The authors reasoned that if a study were highly disruptive, subsequent research would be less likely to cite its references and instead cite the study itself. Using the citation data from 45 million manuscripts and 3.9 million patents, the researchers calculated a measure of disruptiveness called the ‘CD index,’ in which values ranged from –1 for the least disruptive work to 1 for the most disruptive.

The average CD index declined by more than 90% between 1945 and 2010 for research manuscripts (see ‘Disruptive science dwindles’) and more than 78% from 1980 to 2010 for patents. Disruptiveness declined in all analyzed research fields and patent types, even when factoring in potential differences in factors such as citation practices.

‘Disruptive’ science has declined — and no one knows why, Max Kozlov, Nature.

A team of researchers in China has unveiled a technique that — theoretically — could crack the most commonly used types of digital privacy using a rudimentary quantum computer.

The technique worked in a small-scale demonstration, the researchers report, but other experts are skeptical that the procedure could scale up to beat ordinary computers at the task. Still, they Are quantum computers about to break online privacy. Davide Castelvecchi, Naturewarn that the paper, posted late last month on the arXiv repository1, is a reminder of the vulnerability of online privacy.

Quantum computers are known to be a potential threat to current encryption systems. However, the technology is still in its infancy, and researchers typically estimate that it will be many years until it can be faster than ordinary computers at cracking cryptographic keys.

Researchers realized in the 1990s that quantum computers could exploit peculiarities of physics to perform tasks that seem to be beyond the reach of ‘classical’ computers. Peter Shor, a mathematician now at the Massachusetts Institute of Technology in Cambridge, showed in 19942 how to apply the phenomena of quantum superposition and interference to factoring integer numbers into primes — the integers that cannot be further divided without a remainder.

In 1870s Lincoln County, New Mexico, English cattleman John Tunstall hires a wayward young gunman named Billy to join the "Regulators" who live and work on his ranch: Doc ScurlockJose Chavez y ChavezDick Brewer, "Dirty" Steve Stephens, and Charlie Bowdre. Tunstall tries to educate and civilize the young men in his employ and clashes with rival rancher Lawrence Murphy, a well-connected Irishman in league with the corrupt Santa Fe Ring.

One of Murphy's hired hands, McCloskey, joins Tunstall while Doc attempts to court Murphy's ward, Yen Sun. Murphy's men kill Tunstall, leading his lawyer friend Alexander McSween to arrange for the Regulators to be deputized and given warrants for the killers' arrest. Hotheaded Billy challenges Dick's authority as the group's foreman as the Regulators attempt to take Murphy's henchmen alive. Instead, Billy guns down several unarmed men, including McCloskey, whom he suspects of still working for Murphy. Newspapers paint the Regulators as a deadly gang headed by a larger-than-life outlaw, "Billy the Kid."

Make no mistake: Congressmen Eric Cantor, Paul Ryan, and Kevin McCarthy are proud Republicans. But they believe the party had lost sight of the ideals it believes in, like economic freedom, limited government, the sanctity of life, and putting families first. This isn’t your grandfather’s Republican party. These Young Guns of the House GOP—Cantor (the leader), Ryan (the thinker), and McCarthy (the strategist)—are ready to take their belief in the principles that have made America great and translate it into solutions that will make the future even better, solutions that will create private sector jobs, maximize individual freedom, and establish a better world for our children. This groundbreaking book is a call to action that sets forth a plan for growth, opportunity, and commitment to propel this country to prosperity. Together, the Young Guns are changing the face of the Republican party and giving us a new road map back to the American dream.

Young Guns

A New Generation of Conservative Leaders

By Eric Cantor, Paul Ryan, and Kevin McCarthy, published by Simon & Schuster

A Faustian bargain is a pact whereby a person trades something of supreme moral or spiritual importance, such as personal values or the soul, for some worldly or material benefit, such as knowledge, power, or riches. Britannica online

When Kev sought the Speakership previously, he eighty-sixed himself by his gaffe on Benghazi and Hillary Clinton (saying the quiet part out loud) and an alleged affair (when Republicans CARED about things like that). My favorite Kev-ism is the one that came and went like a silent, deadly fart: "I think Putin pays Trump" a month before Orange Satan clinched the nomination, and we've been in the Twilight Zone ever since.

Kevin McCarthy said that the "President bore responsibility for the Capital Riot on January 6," then voted with the insurrectionists who wanted to overthrow a free and fair election. He followed that up with a whirlwind tour of Butt-kissing down at the gaudy resort of the twice-impeached leader of the Republican Party in Florida. He could have invoked the 25th Amendment. He could have whipped the votes in the House from Republican members to support impeachment BOTH times! He raised money for the "Taliban 20" that voted against his Speakership, and Marjorie Taylor, "Secret Jewish Space Lasers," found out the hard way to get what he wants - power - he would lie to even the QUEEN of MAGA. To enter into a Faustian bargain, one assumes "The Kev" had a soul to haggle with the Orange Devil from Mar-a-Lard-o in trade. Jellyfish have more spine.

“Created realities” and the vote for Speaker.

This is the first time in a century that there’s been a failed vote for Speaker. “Kev” is like the Republican Party: no agenda, no platform, and no ideology to govern. All this after copious Butt-kissing on the altar of the graven image of Orange Cheeto. The party has a problem with facts and reality. Kev is the last man standing for the “Young Guns." The Tea Party drove out the former. Kev-o is being driven crazy in prime time.

*****

The aide said that guys like me [Suskind] were "in what we call the reality-based community," which he defined as people who "believe that solutions emerge from your judicious study of discernible reality." I nodded and murmured something about enlightenment principles and empiricism. He cut me off. "That's not how the world works anymore," he continued. "We're an empire now, and we create our own reality when we act. And while you're studying that reality — judiciously, as you will — we'll act again, creating other new realities, which you can study too, and that's how things will sort out. We're history's actors ... and all of you will be left to study what we do." [The New York Times Magazine] Attributed to Karl Rove, which he denies.

*****

The GOP Leader in the House cursed at his chaotic, fractious, raucous caucus, and Gunboat Barbie, Lauren Boebert, cursed him back.

Hakeem Jeffries got 212 votes (in one round), Kev 202, and Jim Jordan 20 after THREE. He failed to get elected Speaker SIX TIMES on Wednesday (by Thursday, as I type this, that count went to ten), and by the House Clerk not gaveling when time expired, it allowed them to sneak a few more votes in to get the ONE successful vote out of seven: to adjourn, and avoid at the time a seventh defeat. Nathanial Banks of Massachusetts holds the longest, most contentious record at 133 - right before the poorly-named Civil War, and I think Kev-a-Tron is going for the Guinness Book of World Records. We now have Kev-bro, or likely Steve Scalese, self-described as "David Duke without the baggage." What did that MEAN, anyway? Even if Kev managed to limp to the Speakership, he's already the WEAKEST Speaker in the nation's history. We haven't gotten to funding the government, raising the debt ceiling, or funding Ukraine against Russian aggression. Whoever's Speaker, the next two years should be "fun." Thanks to Jonah Goldberg, his "fecal festival" observation has become part of my lexicon. So apropos for the two-year anniversary of an insurrection that sadly involved feces and urine from barbarians.

If spineless Kev-muffins wants to “play Speaker” so badly, why doesn’t he BUY a gavel and podium at Walmart or Amazon? It would be FAR cheaper and less humiliating. He could knock himself out all day and post selfies. That is the only functionality other than breathing and going to the bathroom that the “raucous caucus” appears to have mastered. The House Republicans aren’t lawmakers: they’re the logical conclusion of electing the poorly spelled, grammatically challenged comments on Facebook.

Whatever soulless deals "the Kev" promised with the "Space Lasers Caucus," the next Speaker, if it's not him, will have to continue it to maintain a modicum of sanity for as long as humanly possible before like Ryan, Cantor, Boehner, and Kev-ums to leave Arkham Asylum to save it. Al Qaeda, the Taliban (original, and 20), QAnon, MAGA, and all terrorists have the same common goal: make America (not "great”) but ungovernable. If you truly believe that “Government is not the solution to our problem, the government is the problem” (Reagan), you CAN'T ALLOW it to function for anyone other than billionaires. In such a nihilistic, sadomasochistic, Murchassen-by-proxy worldview, this demonstrated chaos to elect a Speaker, without which there IS no 118th Congress, on the second anniversary of the January 6 Insurrection is not a bug: it’s a desired, psychotic feature.

This is embarrassing and has shown the American people that the slim majority the Republicans enjoy should be erased in 2024. They should not be allowed to govern until they take their jobs more seriously than their social media followers.

He’s a ‘Chaos Candidate,’ and He’d Be a Chaos President,’ Jeb Bush. Truer words have never been spoken, and the chaos has become a contagion.

Only two spacecraft have ever left our solar system and lived to tell the tale. In 2012 and 2019, NASA’s Voyager 1 and 2 spacecraft respectively broke through the heliopause, the boundary at which our sun’s sphere of influence gives way to the interstellar medium. They have sent back remarkable riches from this distant location, humanity’s first foray into the limitless bounds beyond our solar system’s edge. Hot pursuit is a far more advanced vehicle, sporting improved instruments, updated optics, and even a means to sample the interstellar medium itself. New Horizons was launched from Earth in 2006 on a mission to visit Pluto, arriving in 2015 and revealing incredible details during its all-too-brief flyby. The spacecraft has continued its cruise toward interstellar frontiers ever since. It has now begun its second extended mission. It is soon set to wake up from a deep hibernation, opening a wealth of new scientific opportunities in the outer solar system. “It takes a long time to get to where our spacecraft is,” says Alice Bowman, mission operations manager for New Horizons at the Johns Hopkins University Applied Physics Laboratory (JHUAPL) in Maryland. “When you have a spacecraft that is out in that part of the solar system, it is a huge asset to the scientific community. There are so many unique things that a spacecraft that is out that far can do. We definitely want to take advantage of that.”

For New Horizons, those “unique things” include unprecedented studies of the planets Uranus and Neptune, sampling of the local dust, studies of the background light in the universe, and more. The sum total will be a new phase of the mission that is “really unique and interdisciplinary in nature,” says Alan Stern, the lead on the mission at the Southwest Research Institute (SwRI) in Texas. In October, this two-year second extended mission officially began, but in 2023 it will pick up the pace as the spacecraft exits hibernation and begins its scientific program in earnest. “There were lots of good ideas for how to do things in astrophysics, heliophysics, and planetary science,” Stern says. “We took the very best of those.” There is even the tantalizing possibility of visiting another object in the Kuiper Belt, the region of asteroids and icy objects that lurks beyond Neptune, in which New Horizons has already visited one object—Arrokoth in 2019—after its Pluto encounter. Even without such a possibility, there was more than enough reason for NASA to extend the mission. “New Horizons is at a unique location in the solar system with an amazing suite of functioning instruments on board,” says Becky McCauley Rench, New Horizons program scientist at NASA Headquarters in Washington, D.C. “[It] can provide valuable insights to the heliosphere and the solar wind, astronomical observations of the cosmic background radiation, and valuable data about Uranus and Neptune that can be applied to our knowledge about ice giant planets.”
