Farmers feed their pigs slop, a messy, wet mix of various leftovers—and when they do, they can say they slop the pigs. A derogatory way to talk about food that doesn't look very tasty is to call it to slop. And you can call sticky, overly sentimental music, writing, or film slop as well. Source: Vocabulary.com

When President Obama used an executive order for deferred action for childhood arrivals (DACA), that was considered constitutional overreach and tyranny from the executive branch. That was likely the executive at the time and the children in question are both brown. This was due to the GOP-dominated Congress not passing a DREAMS Act for those same children's path to citizenship. Immigration reform used to be a thing with republicans: Saint Ronald Reagan made a whole bunch of illegal immigrants citizens, and that might have contributed to the high numbers his republican successor, George W. Bush enjoyed for his 2004 reelection. That compassionate conservatism advantage has been dwindling ever since, at least until our current moment of discontent.

Ben Sasse called Orange Satan's executive orders unconstitutional slop, which it is. His clap back to the middle school mean-girl tweetstorm from Mango Mussolini is an admittance: "I don't need you to get reelected, you need me." He like a lot of other Republican senators had their constitutional duty to remove a criminal from office. They are the beneficiaries of Jim Crow, the Southern Strategy, Voter Purging, and Suppression. They shirked it because they are criminals themselves. Conditional integrity is still cowardice.

HuffPost senior White House correspondent S.V. Dáte asked the president during Thursday’s coronavirus task force briefing if, after 3½ years, “do you regret at all the lying you’ve done to the American people? All the dishonesties?”

“That who has done?” Trump replied. 

“You have done,” said Dáte, who wrote at length about Trump’s “Ministry of Untruth” earlier this year. 

Trump paused and then moved on to the next question.

In his report, Dáte noted that Trump’s stream of falsehoods across nearly every topic and in any setting is corroding America’s democracy as it normalizes lies coming from the nation’s highest office.

Trump's Response When Asked If He Regrets All The Lies He's Told America: None, Josephine Harvey, HuffPost

We have a view of history that fascism doesn't need competency. Hitler was quite literally a shit show, and the mythology of Nazi efficiency is...just that.

It's poignant that Senator Kamala Harris is African Diaspora through her Jamaican father and Indian Diaspora through her mother - both immigrants who met in Oakland, California where she and her sister were born as American citizens. Both marched and shouted for Civil Rights for all its citizens, especially their daughters, as civil rights have never had a hue, simply for and of humans. America, India, Germany have had and have caste systems that assign portions of humanity to either the apex of the pyramid where all riches are siphoned to or the base where all the weight of society crushes pariahs beneath it. She's a woman that self-identifies with black culture through her HBCU - Howard University and her Sorority, Alpha Kappa Alpha. She married another human that happens to be of European descent. She is above all, an earthling, and Oakland isn't a crater on Mars. Her fraternity brother, Dr. Martin Luther King, Jr - found himself in an inflection of revelation.

Caste (Oprah's Book Club): The Origins of Our Discontents, Isabelle Wilkerson

In 1935, Nazi Germany passed two radically discriminatory pieces of legislation: the Reich Citizenship Law and the Law for the Protection of German Blood and German Honor. Together, these were known as the Nuremberg Laws, and they laid the legal groundwork for the persecution of Jewish people during the Holocaust and World War II.

When the Nazis set out to legally disenfranchise and discriminate against Jewish citizens, they weren’t just coming up with ideas out of thin air. They closely studied the laws of another country. According to James Q. Whitman, author of Hitler’s American Model, that country was the United States.

“America in the early 20th century was the leading racist jurisdiction in the world,” says Whitman, who is a professor at Yale Law School. “Nazi lawyers, as a result, were interested in, looked very closely at, [and] were ultimately influenced by American race law.”

In particular, Nazis admired the Jim Crow-era laws that discriminated against black Americans and segregated them from white Americans, and they debated whether to introduce similar segregation in Germany.

Yet they ultimately decided that it wouldn’t go far enough.

How the Nazis Were Inspired by Jim Crow, Becky Little, History.com

Fascism, like its cousin racism, doesn't need rationality over "us" and "them." It allows one group to dominate another without guilt, or blame for the consequences. It allows you to long for mythological glory times where Germany and America were "great again."

Fascism in Germany or America just needed enablers, and frankly, intellectuals that underestimate how a cornered animal - hog, rodent or narcissist - is its most dangerous and cunning when it figures it's going to die in prison and has nothing - other than its freedom - to lose.

Source: Ceresva.org

WASHINGTON (Reuters) - Ceres, the largest object in the asteroid belt between Mars and Jupiter, is an “ocean world” with a big reservoir of salty water under its frigid surface, scientists said in findings that raise interest in this dwarf planet as a possible outpost for life.

Research published on Monday based on data obtained by NASA’s Dawn spacecraft, which flew as close as 22 miles (35 km) from the surface in 2018, provides a new understanding of Ceres, including evidence indicating it remains geologically active with cryovolcanism - volcanoes oozing icy material.

The findings confirm the presence of a subsurface reservoir of brine - salt-enriched water - remnants of a vast subsurface ocean that has been gradually freezing.

“This elevates Ceres to ‘ocean world’ status, noting that this category does not require the ocean to be global,” said planetary scientist and Dawn principal investigator Carol Raymond. “In the case of Ceres, we know the liquid reservoir is regional scale but we cannot tell for sure that it is global. However, what matters most is that there is liquid on a large scale.”

Photovoltaic cells made from cadmium telluride (CdTe) – already widely used in solar energy generation – also excel at harvesting ambient light indoors, making them an excellent energy source for the fast-growing Internet of Things (IoT). This is the finding of researchers at the Massachusetts Institute of Technology (MIT) in the US and the Tyndall National Institute at the University of Cork, Ireland, who fabricated low-cost CdTe cells and measured their photovoltaic response when exposed to light from various sources, including LED bulbs.

At present, indoor IoT devices such as wireless sensors are typically powered by batteries.  However, study lead author Ian Mathews says that photovoltaic cells would be better because of they require less maintenance and are cheaper and easier to make. In his view, these characteristics present a “significant market opportunity” for CdTe cells in particular, yet researchers have rarely tested their effectiveness at converting ambient light (from incandescent, compact fluorescence, or LED bulbs, for example) into electrical energy. Instead, previous studies of indoor-light energy generation have mainly focused on rival photovoltaic technologies, such as silicon, III-V semiconductors, organic PV devices, and perovskite materials.

Quantum Hush...

Party line: the new protocol allows 10 parties to share information securely. (Courtesy: University of Witwatersrand)

Topics: Cryptography, Quantum Computer, Quantum Mechanics

A “quantum secret sharing” scheme that allows 10 parties to share information securely – the highest number so far – has been developed and demonstrated by researchers in South Africa. The protocol involves each party performing quantum operations on the photon without measuring its state and the team says it could help increase both the rate at which data is shared on secure quantum networks and how many parties can be involved in the sharing.

In the original quantum key distribution (QKD) protocol, two parties, known as Alice and Bob, communicate by exchanging photons polarized in one of two possible bases over an untrusted link, each varying the polarization basis of his or her transmitter or receiver randomly. At the end of the transmission, Alice and Bob reveal to each other which basis they used to measure the photons sent and received, but not the result of the measurements.  Alice and Bob then announce their results for a sample of the photons in which they measured in the same polarization basis, to check that the emitted polarization always agrees with the received one. If it does, they can use the remaining photons that they measured in the same basis to form a secure cryptography key that allows them to communicate securely using conventional telecoms technology. A third party that intercepts the photons inevitably disturbs their state, so some of Alice and Bob’s measurements disagree and they know the line is bugged.

Holographic Microscopy...

Figure

FIG. 1. (a) Schematic of an inline digital holographic microscope. In a typical setup, a collimated laser (light red) illuminates a sample, which scatters light (dark red wavefronts). The transmitted and scattered light passes through an objective and tube lens, which focuses the light onto a digital camera.

Topics: Holography, Optical Physics, Microscopy, Modern Physics

In the past few years, the venerable field of holographic microscopy has been revitalized by computational data analysis. It is now possible to fit a generative (forward) model of scattering directly to experimentally obtained holograms of complex microscopic objects. This approach enables precision measurements: it allows the motion of colloidal particles and biological organisms to be tracked with nanometer-scale precision and their optical properties to be inferred particle by particle. In this Perspective, we discuss how the model-based inference approach to holographic microscopy has opened up new applications. We also discuss how it must evolve to meet the needs of emerging applications that demand lower systematic uncertainties and higher precision. In this context, we present some new results on how modeling the optical train of the microscope can enable better measurements of the positions of spherical and nonspherical colloidal particles. Finally, we discuss how machine learning might play a role in future advances. Though we do not exhaustively catalog all the developments in this field, we show a few examples and some new results that spotlight open questions and opportunities.

Occam's Razor and Scorched Earth...

 

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

As Chancellor, Gerhard Schröder was a strong advocate of the Nord Stream pipeline project, which aims to supply Russian gas directly to Germany, thereby bypassing transit countries.

At the time of the German parliamentary election, according to Rick Noak of The Washington Post:

In 2005, Russian President Vladimir Putin’s friend Schroeder hastily signed the deal just as he was departing the office from which he had been voted out days earlier. Within weeks, he started to oversee the project implementation himself, leading the Nord Stream AG’s shareholder committee.

Wikipedia: Gerhard_Schröder-Relationship_with_Gazprom_and_Rosneft

Occam’s razor, also spelled Ockham’s razor, also called law of economy or law of parsimony, principle stated by the Scholastic philosopher William of Ockham (1285–1347/49) that pluralitas non est ponenda sine necessitate, “plurality should not be posited without necessity.” The principle gives precedence to simplicity: of two competing theories, the simpler explanation of an entity is to be preferred. The principle is also expressed as “Entities are not to be multiplied beyond necessity.” Source: Britannica online

Occam's razor: Orange Satan spoke two consecutive days to Grand Pooh-Bah Putin; 16 or more private conversations last year (in the current Coronavirus apocalypse, we'll refer to that as the "before times"). He's managed to without fail insult every [former] ally we've had since the end of the Second World War, but not even a nickname for Vlad the Impaler of democracies. What he says in those conversations that like his salary, we're paying is apparently none of our business. We can't see his grades, SAT scores, or his taxes. Al Capone wasn't too keen about the idea of revealing his taxes either, and that ultimately is what landed him in prison. A guy who had "Joey No Socks" at his New Year's bash after Pooh-Bah gifted him the 2016 election and planet is probably a crook. The producers and showrunners of "The Apprentice" was in on the joke, as well as most residents of New York City. He's not a businessman, except of the Keystone Cop variety, every decision is a pratfall and every pronouncement word salad. Case-in-point: you're reading this during a pandemic. His lack of talent in his 74 years of wasting oxygen and producing flatulence at wee tweet hours has been covered by white male privilege, his father, the Mafia, Russian money laundering, and republicans that never once believed their own shtick. Enter Bizarro Capone with a dead Propecia ferret on his head yelling manically "he can fix it."

The "empty vessel" model was introduced by Reagan: as he deteriorated, others like William Barr worked the marionette strings from the shadows as Ronnie "aw shucks" himself into B-movie legend. Mind you, "nature abhors a vacuum," but Donnie just "isn't there." He doesn't say "aw shucks": he might say "oh, fuck," or "oh, I'M fucked."

Nixon - Roger "rat fuck" Stone's back tattoo totem - was unscrupulous, but he was competent: Affirmative Action and the Environmental Protection Agency just two of his accomplishments, other than the whole Watergate Plumber's thing. Simultaneously insulting a landmark and a culture by saying "yo-Semite" ("yo-sim-e-T," idiot!) isn't the "stable genius" his twisted mind and cognitively dissonant followers believes himself to be.

EIGHT republican "patriot" senators were in Moscow on July 4, 2018, months before the midterms. That's strange for patriots (Tom Clancy is confused in the hereafter), especially on the nation's birthday. Probably totally innocent. Good luck with the 2nd Amendment, over there: it doesn't exist.

The Republican Party is shrinking. The Southern Strategy was great for Nixon in 1968, and cool for Reagan in the 80's nostalgic "Back to the Future" decade, when Lee Atwater resurrected the ghoulish grog in "welfare queens", "young bucks", and Willie Horton when Pappy ran in '88, which actually means something to white supremacists. 52 years into the future, any milk left on the shelf that long would be rancid, if not mummified.

So, what do you do when your shtick is shit, your base is melting by the 2nd Law of Thermodynamics and you just can't win legitimate elections anymore? Domestically, that takes the form of a faux war on faux voter fraud, voter purges and voter suppression of the groups that probably won't vote for endless tax cuts for the 1%, genteel racism and not-so-subtle sexism and homophobia. Internationally, you might "get a little help" from your Russian friends, and make sure they can still help.

Jill Stein, Gary "Aleppo" Johnson, and for God's sake, red hat KANYE are not going to BE president!

And, what if you lose and you don't accept it? A lunatic currently has the nuclear codes and twitchy Twitter fingers.

It's 87 days to the election (yesterday was 88).

It's 165 days to the inauguration of the NEXT president.

Tomorrow is after that.

Quantum Dots and Diffusion...

QD tracking

Topics: Biology, Diffusion, Quantum Dots, Quantum Mechanics

Quantum dots diffuse within living cells in a nearly two-dimensional fashion. This result, which was obtained using a new 3D microscopy technique that can track single particles, sheds fresh light on intracellular diffusion – a process that is critical for moving molecules around the cell and for mediating other important activities. According to study leader Hui Li, a biophysicist at the Chinese Academy of Sciences in Beijing and Beijing Normal University, the 2D motion he and his colleagues observed is robust and stems from the complex architectures of the flat “adherent” biological cells they studied.

Quantum dots make ideal probes for studying intracellular diffusion in living cells. They are similar in size to intracellular macromolecules and can be made to mimic biological materials relatively easily, by coating their surfaces with organic molecules. Previous studies, however, relied mainly on two-dimensional measurements of their movement, with the assumption that three-dimensional diffusion is an extension of 2D diffusion and is isotropic.</em>

Blind Mice Seeing...

Topics: Bioengineering, Optical Physics, Nanorods, Nanotechnology

Even in the dark, rattlesnakes and their fellow pit vipers can strike accurately at small warm-blooded prey from a meter away. Those snakes, and a few others, can see in the IR—but not with their eyes. Rather, they have a pair of specialized sensory organs, called pit organs, located between their eyes and their nostrils and lined with nerve cells rich in temperature-sensitive proteins that cause the neurons to fire when heated.1 The pits work like pinhole cameras to focus incoming thermal radiation onto their heat-sensitive back walls; the thermal images are then superimposed with visual images in the snake’s brain.

Heat-responsive neurons are not unique to snakes. We have them over every inch of our skin, to feel objects warm to the touch, and on our tongues, to taste spicy food. But the snakes’ ability to resolve the source of radiated heat at a distance is unusual.

Inspired by the snakes, Dasha Nelidova and her colleagues at the Institute of Molecular and Clinical Ophthalmology in Basel, Switzerland, are developing a new treatment for forms of blindness caused by the degeneration of retinal photoreceptors.2 Using gene therapy, they endow remaining retinal cells with thermoresponsive proteins, thereby compensating for their lost light sensitivity with heat sensitivity. The proteins by themselves aren’t sensitive enough to rival normal vision, so the researchers tether them to gold nanorods, as shown in figure 1. The 80-nm-long nanorods strongly absorb near-IR light at 915 nm and convey the concentrated heat to the attached proteins.

Gaming This Out...

Because of the recent changes in my previous platform, I am discontinuing https://www.physics4thecool.blogspot.com and continuing on WordPress and BSFS. What follows is the post I meant for Blogger. I will miss it.

The current first Tuesday of November came into law in the year 1845, when America was an agrarian society, and it took a day’s travel to get to one’s polling place to exercise the franchise. It was also 15 years before the Civil War that ripped the country apart pitting north against south, industrialists against plantation slavery owners. It was a time when my people were considered 3/5th of a person, and the conception of John Robert Lewis and Barack Hussein Obama never would have entered the mostly white male property owner's thinking.

Orange Satan doesn’t have the power to alter the date of the November 3rd election. His tweet came 16 minutes into the speech above. It was also minutes from the GDP dipping 32.9%, lower than it’s ever dipped in history. The Coronavirus has defied all happy talk, magical thinking and vindictive revenge porn, seeing the initial infection hot spots were in blue states. I probably would have wanted to talk about something else as well.

But, what if it’s something far more sinister entirely? He will sincerely try to steal or cast doubt in the election. He will use Russia, China, Iran; the Abominable Snowman, because “playing by the rules” is something his spoiled brat ass never had to do. He will behave like a cornered rat, he’ll do anything to survive, not excluding refusing to leave the Oval Office. We should have contingency plans for a protracted, dramatic, televised brawl: worthy of reality TV. He’s preparing to do what he does best: tie it up in court to wear down his opponents – the American people – to just quit. “Peaceful transition” means prison time for him, and until January 20, 2021, Mango Mussolini has the nuclear codes.

The hallmark of American Democracy was always the “peaceful transition of power.” This assumed everyone played by the same rules, abide by the same reality, and generally of good character, thinking of the country far above anything they could achieve for themselves. We’re obviously not there now. Orange Satan is the personification of fear: fear of the future and the inevitable change in demographics the passage of time brings. It was the core of right wing AM talk radio that evolved to the airwaves and a certain network owned by an Aussie and Saudi prince (so “American”), spewing nightly feces that amounts to mental propaganda and bullshit.

In yesterday’s final lauding of John Robert Lewis by three presidents that didn’t need foreign help and could actually string coherent sentences together, each took their subtle and not-so-subtle swipes at the current Manchurian Puppet. The Civil Rights Movement only looked at the founding documents of this republic, and asked the simple question: are we Americans? After 400 years, and serving this country in every war since Crispus Attucks first died for the American Revolution, the compound interest from “40 acres and a mule” is astronomical, but the wounds of daily racial hatred; the perpetual knee-on-neck of the body politic is exhausting. 400 years to George Floyd is literally, the “patience of Job” on steroids.

The United States is a democracy because of black people.

When in the Course of human events it becomes necessary for one people to dissolve the political bands which have connected them with another and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature’s God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. — That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

Now, that’s the “noble” part.

Peruse down a little further in the document: “He (ahem: King George of England) has excited domestic insurrections amongst us, and has endeavoured to bring on the inhabitants of our frontiers, the merciless Indian Savages whose known rule of warfare, is an undistinguished destruction of all ages, sexes and conditions.” That part wasn’t covered in the Broadway Musical, “Hamilton.”

Reference: U.S. History: Declaration of Independence

Frederick Douglass said: “Knowledge makes a man unfit to be a slave.” As Joy Reid of MSNBC eluded, we read it. We decided we wanted it. People like Crispus Attucks, Frederick Douglass, Medgar Evers, Malcolm X, Martin Luther King and John Robert Lewis struggled and died for it, and their progeny have decided we WANT it.

The United States is nominally a Christian nation because of black people.

The alien who resides with you shall be to you as the citizen among you; you shall love the alien as yourself, for you were aliens in the land of Egypt: I am the Lord your God. Leviticus 19:34

I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me. Matthew 25:35

Do not neglect to show hospitality to strangers, for thereby some have entertained angels unawares. Hebrews 13:2

We are the 400-year strangers and angels among you, that you hang, shoot, and strangle all day long.

We are either human or not. We are either fully Americans or not.

This is either a democracy, or it’s a modern American Bund.

“Though I may not be here with you, I urge you to answer the highest calling of your heart and stand up for what you truly believe. In my life, I have done all I can to demonstrate that the way of peace, the way of love and nonviolence is the more excellent way. Now it is your turn to let freedom ring.

“When historians pick up their pens to write the story of the 21st century, let them say that it was your generation who laid down the heavy burdens of hate at last and that peace finally triumphed over violence, aggression and war. So I say to you, walk with the wind, brothers and sisters, and let the spirit of peace and the power of everlasting love be your guide.” John Robert Lewis, the Angel that was among us, New York Times

"I have fought the good fight, I have finished the race, I have kept the faith." 2 Timothy 4:7

While my time here has now come to an end, I want you to know that in the last days and hours of my life you inspired me. You filled me with hope about the next chapter of the great American story when you used your power to make a difference in our society. Millions of people motivated simply by human compassion laid down the burdens of division. Around the country and the world, you set aside race, class, age, language and nationality to demand respect for human dignity.
 

That is why I had to visit Black Lives Matter Plaza in Washington, though I was admitted to the hospital the following day. I just had to see and feel it for myself that, after many years of silent witness, the truth is still marching on.

Emmett Till was my George Floyd. He was my Rayshard Brooks, Sandra Bland, and Breonna Taylor. He was 14 when he was killed, and I was only 15 years old at the time. I will never ever forget the moment when it became so clear that he could easily have been me. In those days, fear constrained us like an imaginary prison, and troubling thoughts of potential brutality committed for no understandable reason were the bars.

Though I was surrounded by two loving parents, plenty of brothers, sisters, and cousins, their love could not protect me from the unholy oppression waiting just outside that family circle. Unchecked, unrestrained violence and government-sanctioned terror had the power to turn a simple stroll to the store for some Skittles or an innocent morning jog down a lonesome country road into a nightmare. If we are to survive as one unified nation, we must discover what so readily takes root in our hearts that could rob Mother Emanuel Church in South Carolina of her brightest and best, shoot unwitting concertgoers in Las Vegas and choke to death the hopes and dreams of a gifted violinist like Elijah McClain.

Like so many young people today, I was searching for a way out, or some might say a way in, and then I heard the voice of Dr. Martin Luther King Jr. on an old radio. He was talking about the philosophy and discipline of nonviolence. He said we are all complicit when we tolerate injustice. He said it is not enough to say it will get better by and by. He said each of us has a moral obligation to stand up, speak up, and speak out. When you see something that is not right, you must say something. You must do something. Democracy is not a state. It is an act, and each generation must do its part to help build what we called the Beloved Community, a nation and world society at peace with itself.

Ordinary people with extraordinary vision can redeem the soul of America by getting in what I call good trouble, necessary trouble. Voting and participating in the democratic process are key. The vote is the most powerful nonviolent change agent you have in a democratic society. You must use it because it is not guaranteed. You can lose it.

You must also study and learn the lessons of history because humanity has been involved in this soul-wrenching, existential struggle for a very long time. People on every continent have stood in your shoes, through decades and centuries before you. The truth does not change, and that is why the answers worked out long ago can help you find solutions to the challenges of our time. Continue to build union between movements stretching across the globe because we must put away our willingness to profit from the exploitation of others.

Though I may not be here with you, I urge you to answer the highest calling of your heart and stand up for what you truly believe. In my life, I have done all I can to demonstrate that the way of peace, the way of love and nonviolence is the more excellent way. Now it is your turn to let freedom ring.

When historians pick up their pens to write the story of the 21st century, let them say that it was your generation who laid down the heavy burdens of hate at last and that peace finally triumphed over violence, aggression and war.

After years of anticipation, NASA hopes to launch its latest robotic explorer, Perseverance, to Mars on Thursday, July 30, at 7:50 A.M. EDT. Set to depart Earth atop an Atlas V-541 rocket from historic Launch Complex 41 at Cape Canaveral Air Force Station in Florida, the ambitious rover is the latest in a long lineage of rolling robotic explorers that NASA has sent to the Red Planet.

If Mars 2020 is not able to blast off during its two-hour launch window tomorrow morning — due to hazardous weather or unforeseen technical issues — the space agency will have just two more weeks to get it done. That’s because after August 15, Mars and Earth will no longer be aligned in a way that allows for quick interplanetary travel, meaning NASA would have to store the rover for two years until the next favorable alignment.

“We have four objectives,” Ken Williford, Deputy Project Scientist for NASA’s Mars 2020 mission, told Astronomy earlier this year. “The first three are really our core science objectives. And the fourth is … preparing for human exploration.”

Perseverance’s science objects are: seeking out sites that were potentially habitable in the past, looking for signs of ancient microbes within rocks known to preserve life, and collecting and storing promising rock samples for a future return mission.

Quantum Phase Battery...

Topics: Battery, Cooper Pairs, Materials Science, Quantum Mechanics, Superconductivity

Researchers in Spain and Italy have constructed the first-ever quantum phase battery – a device that maintains a phase difference between two points in a superconducting circuit. The battery, which consists of an indium arsenide (InAs) nanowire in contact with aluminium (Al) superconducting leads, could be used in quantum computing circuits. It might also find applications in magnetometry and highly sensitive detectors based on superconductors.

In a classical battery (also known as the Volta pile), chemical energy is converted into a voltage difference. The resulting current flow can then be used to power electronic circuits. In quantum circuits and devices based on superconducting materials, however, current may flow without an applied external voltage, thus dispensing with the need for a classical battery.

The concept of a quantum phase battery was studied theoretically in 2015 by Sebastián Bergeret of the Material Physics Center (CFM-CSIC) and Ilya Tokatly at the University of the Basque Country in Donostia-San Sebastián, Spain. Their battery design comprised a combination of superconducting and magnetic materials and was based on a Josephson junction – a non-superconducting region through which the Cooper pairs responsible for superconductivity can tunnel. This semiconducting “weak link” provides a persistent phase difference between the superconductors in the circuit, similar to the way that a classical battery provides a persistent voltage drop in an electronic circuit. Thanks to this phase difference, a superconducting current (that is, a current with zero dissipation) flows when the junction is embedded in the superconducting circuit.

This will be the first splashdown that's occurred in a while, but particularly during a global pandemic and the internment of a legend. It was germane during the Mercury, Gemini and Apollo programs. The Space Shuttle brought to mind the CGI and FX ease of take offs and landings in Science Fiction movies, regardless of genre: somehow massive spaceships can magically levitate, and "ease" into orbit without accelerating to escape velocity in a planet's gravity well.

Today, we're laying to rest a civil rights icon, John Robert Lewis. He was BLM before the Internet and hashtag. He was notorious for getting in "good trouble," leading a sit-in on the House floor - breaking rules for twenty children and six adults slaughtered at Sandy Hook, for what he and Dr. King called "The Beloved Community." Like moonshots, that was "conspiracy theorized" away, callously, but revelatory of how depraved this republic was before this current moment. Hopefully, the citizens of Alabama will rename the bridge currently carrying the name of a confederate traitor and Klan grand dragon in HIS distinct honor.

During splashdowns and pandemics: I can dream.

NASA will provide live coverage of activities leading up to, during, and following the return of the agency’s SpaceX Demo-2 test flight with the agency’s astronauts Robert Behnken and Douglas Hurley from the International Space Station.

The duo arrived at the orbiting laboratory on May 31, following a successful launch on May 30 on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida.

NASA and SpaceX are targeting 7:34 p.m. EDT Saturday, Aug. 1, for undocking of the Dragon “Endeavour” spacecraft from the space station and 2:42 p.m. Sunday, Aug. 2, for splashdown, which will be the first return of a commercially built and operated American spacecraft carrying astronauts from the space station.

Coverage on NASA TV and the agency’s website will begin at 9:10 a.m., Aug. 1, with a short farewell ceremony on station and resume at 5:15 p.m., with departure preparations through splashdown and recovery at one of seven targeted water landing zones in the Atlantic Ocean or Gulf of Mexico off the coast of Florida.

All media participation in news conferences and interviews will be remote; no media will be accommodated at any NASA site due to the ongoing COVID-19 pandemic. To participate in the briefings by phone or to request a remote interview with the crew members, reporters must contact the newsroom at NASA’s Johnson Space Center in Houston at 281-483-5111 no later than two hours prior to each event.

We have always held to the hope, the belief, the conviction that there is a better life, a better world, beyond the horizon. Franklin D. Roosevelt

At 1 pm eastern, 12 noon in San Antonio, my wife's family laid her favorite uncle to rest, a U.S. veteran. He died due to health complications, non-COVID. Because of the pandemic, we had to say our tearful goodbyes over Facebook live, the participants' voices muffled by masks singing "It is Well." He lived a good life, into his eighties, longer than my own father, but his sons probably don't take solace in his longevity: their hero is gone for now.

Dr. Eddie Glaude, Jr's book on James Baldwin downloaded on my Kindle about a week before Dr. Mary Trump's book about her uncle. They are my mental comfort food between writing a research proposal: a book written by an African American heterosexual professor about an LGBT Civil Rights icon, and a book about an unstable, reckless sociopath, written by his niece, a Lesbian, a notion now in a world with Ellen DeGeneres and Rachel Maddow is almost cliche. "Jimmy" was out and proud before it was relatively safe, or sane. He literally could have been killed for "the color of his skin, and the content of his character." But that did not stop or stifle his boldness.

“I love America more than any other country in the world and, exactly for this reason, I insist on the right to criticize her perpetually.” ― James Baldwin

We are "betwixt and between" the past and the future: one written and one yet-to-be written, first by John Lewis and now, Black Lives Matter et al. We are betwixt and between love and hate, democracy and fascism; working towards a more perfect union, and barreling towards totalitarianism. The philosophies of Hitler, Goebbels and Himmler are personified in Bannon, Gorka and Miller, fascist whisperers recycling hate in the 21st century: the ovens now microscopic, efficient, utterly malevolent, and unseen. We are seeing the NRA's "jackbooted thugs" deployed in American cities - Portland, Oregon, soon Chicago, Illinois; our nation's birthplace in Philadelphia, Pennsylvania and any other blue-governed city, without a peep from them, as deafening a silence now as for the death-by-police of the licensed gun owner, Philando Castile. The second amendment might be outlawed to Melanin in a dictatorship.

The best political weapon is the weapon of terror. Cruelty commands respect. Men may hate us. But, we don't ask for their love; only for their fear. Heinrich Himmler, commander of the German Schutzstaffel (SS) and Gestapo.

“We are now faced with the fact that tomorrow is today. We are confronted with the fierce urgency of now. In this unfolding conundrum of life and history, there "is" such a thing as being too late. This is no time for apathy or complacency. This is a time for vigorous and positive action.” ― Martin Luther King Jr.

For Dr. Eddie Glaude, Jr., that fierce urgency is he, I and previously "Jimmy" living in these black bodies, witnessing the country careen from "hope and change" to this dark moment of running over civil rights demonstrators in Charlottesville, Nazis in polo shirts carrying tiki torches; or teargassing peaceful George Floyd demonstrators on the Washington Mall. Once we got over the "post-racial America" shtick, it didn't take long to see the new black president hung in effigy, called the n-word almost daily, burned at the stake, bone through the nose as witch doctor for the pejorative: Obamacare. They prayed Psalm 109:8-15, for his death and desolation. They are anti-Christians for an Antichrist. Their hatred of immigrants in chat rooms and over the pit of hell summoned eventually a demon, who recycled for them Hitler, the Klan and Reagan's slogan: make America great again. Exposed in Dr. Glaude's treatise was what Eddie and "Jimmy" referred to as the American lie, broadcast with the hubris of a birther foghorn.

For Dr. Mary Trump, that fierce urgency was living through a slow train wreck: watching her father, Freddy - Fred Trump's namesake - taken apart by her grandfather brick-by-brick until there was nothing left. She could still live in the comfort of privilege, station and American aristocracy: her bloodline leading directly to the seat of power almost infinite. All she had to do was keep her head low and flatter a narcissist. Her clinical training tells her there is no pleasing such a person. His needs are a bottomless pit next to a black hole. His loyalty is demanded of others and expendable to the same. Just as the senior sociopath dismantled her father, her training said a prolific lying, mentally disturbed, gaslighting and violent man could dismantle a nation.

Mary L. Trump, Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man

Perhaps she thought of Martin Niemöller:

First they came for the socialists, and I did not speak out—because I was not a socialist.

Then they came for the trade unionists, and I did not speak out— because I was not a trade unionist.

Then they came for the Jews, and I did not speak out—because I was not a Jew.

Then they came for me—and there was no one left to speak for me.

It is easy to fill in the blank now: African Americans, Hispanics/Latinos, Women, Homosexuals, Lesbians, Transgenders: if we do not speak for our fellow humans, we follow them into the COVID ovens. A pandemic as eugenics is far more efficient, less visible and more excusable than public crematoriums.

I still have hope. I have to. I have a granddaughter barely over a year old, and she DESERVES a future.

Politics in America especially is organized tribalism. The factions George Washington warned about in his farewell address express themselves as republicans and democrats, along with greens and independents.

We are all between yesterday and tomorrow, living out our hyphens. We are ever all in "the fierce urgency of NOW" for tomorrow. We all have children, or know children, and a world that looks like a dystopian novel is only appealing to sociopaths, mass murderers and death cult members. A world like that has few children, and the human species - Coronavirus, climate change, or nuclear exchange - is then in peril.

For this election, for humanity, we have to ALL be Americans, and heroes in the spirit of John Lewis: voting by mail, voting early, getting in "good trouble" for this fleeting, precious thing called democracy: made real by the struggles of the downtrodden and "the least of these." For "the fierce urgency of now," for a "better world beyond the horizon"... for tomorrow.

“never lose sight, as we finger the pain and disillusionment of our after times, of the possibility of a New Jerusalem.” ― Eddie S. Glaude Jr., Begin Again: James Baldwin's America and Its Urgent Lessons for Our Own

Twins of a Young Sun...

The first direct image of two exoplanets orbiting a Sun-like star, seen here, was captured by the SPHERE instrument on the ESO’s Very Large Telescope. The system is called TYC 8998-760-1 and is located some 300 light-years from Earth.

In another exoplanetary first, the European Southern Observatory's Very Large Telescope (VLT) in Chile's Atacama Desert has captured an image of two worlds orbiting a younger version of the Sun. The system, called TYC 8998-760-1, is located roughly 300 light-years away in the southern constellation Musca. And although it hides two gas giants orbiting a Sun-like star, we don’t have anything quite like these worlds in our own solar system.

The inner planet lies about 160 astronomical units from its host star (where one astronomical unit, or AU, is the average Earth-Sun distance) and is some 14 times the mass of Jupiter. With that amount of heft, the gas giant skirts the border between planet and brown dwarf, which is a type of almost-star. The more distant planet is located about 320 AU from its star and weighs in at about six Jupiter masses.

Starspots and Red Giants...

Some red-giant stars are rotating much faster than previously thought, according to a study led by Patrick Gaulme at Germany’s Max Planck Institute for Solar System Research. Using NASA’s Kepler space telescope, the astronomers found that about 8% of the red giants they observed are rotating fast enough to display starspots. The team reckons that the elderly stars acquire their rapid rotation by following one of three distinct routes in their evolution.

In main sequence stars like the Sun, the complex interplay that occurs between stellar rotation and the motions of plasma creates incredibly lively magnetic fields. When this magnetic activity is particularly strong, upwelling plumes of plasma in a star’s convective outer layers can be blocked, producing dark patches on its surface. To an observer on Earth, these starspots cause a periodic variation in the star’s brightness as it rotates, bringing the spots in and out of our field of view.

Until recently, starspots were not thought to be present on red giant surfaces. Since these older stars expand rapidly as they move out of the main sequence, while maintaining their angular momentum, previous theories had predicted that they must rotate more slowly than main sequence stars. Slower rotation should reduce magnetic activity, preventing starspots from forming.

Comet NEOWISE...

Topics: Astronomy, Astrophysics, Comets

Comet NEOWISE has been entertaining space enthusiasts across the Northern Hemisphere. Although its official name is C/2020 F3, the comet has been dubbed NEOWISE after the Near-Earth Object Wide-Field Infrared Survey Explorer (NEOWISE) space telescope that first noticed it earlier this year. This “icy snowball” with a gassy tail made its closest approach to the sun on July 3 and is now heading back from whence it came: the far reaches of the outer solar system. Its long, looping orbit around our star ensures that after passing closest to Earth on July 22, Comet NEOWISE will not return for some 6,800 years.

Even though the comet is now bright enough to observe with unaided eyes, inexperienced stargazers might have trouble knowing when and where to look. Scientific American spoke to Jackie Faherty, an astronomer at the American Museum of Natural History in New York City, for observing tips and a better appreciation of why comets are so special.

How does one prepare to watch Comet NEOWISE with the naked eye?

Find the darkest possible swath of sky and make sure your eyes are adjusted so that you give yourself the best possible opportunity to see faint objects. It means: don’t just walk outside after staring at lights or screens and expect to see [the comet] really well. You need 15 minutes or so to adjust your eyes, so that your pupils are adjusted, and they’re used to seeing fainter things. It’s the same as walking into a dark room, and everybody knows that [you] can’t see [things] first—and then, all of a sudden, you start seeing things. You need to do the same thing when you walk outside. And use the Comet NEOWISE app developed by astrophysicist Hanno Rein of University of Toronto Scarborough to see exactly where it is, so that you know what direction you need to look. And then the key would be to find yourself a place that is the darkest possible, that [has] no lights.

On June 21, 1964, three young men disappeared near the town of Philadelphia, Mississippi. Michael (Mickey) Schwerner and James Chaney worked for the Congress of Racial Equality (CORE) in nearby Meridian; Andrew Goodman was one of the hundreds of college students from across the country who volunteered to work on voter registration, education, and Civil Rights as part of the 1964 Mississippi Summer Project. The three men believed their work was necessary, but also dangerous: Ku Klux Klan membership in Mississippi was soaring in 1964 -- with membership reaching more than 10,000. The Klan was prepared to use violence to fight the Civil Rights movement; on April 24 the group offered a demonstration of its power, staging 61 simultaneous cross burnings throughout the state.

The case was drawing national attention, in part because Schwerner and Goodman were both white Northerners. Mickey Schwerner's wife Rita, who was also a CORE worker, tried to convert that attention to the overlooked victims of racial violence. “The slaying of a Negro in Mississippi is not news. It is only because my husband and Andrew Goodman were white that the national alarm has been sounded,” she told reporters during the search.

Throughout July, investigators combed the woods, fields, swamps, and rivers of Mississippi, ultimately finding the remains of eight African American men. Two were identified as Henry Dee and Charles Moore, college students who had been kidnapped, beaten, and murdered in May 1964. Another corpse was wearing a CORE t-shirt. Even less information was recorded about the five other bodies discovered.

Finally, after six weeks of searching, a tip from an informant -- later identified as Mississippi Highway Patrol officer Maynard King -- sent investigators to an earthen dam on the Old Jolly Farm outside Philadelphia. It was there that the FBI uncovered the bodies of Schwerner, Chaney, and Goodman on August 4.

Russian financial traffic got to the Taliban in Afghanistan: intelligence wouldn't use the word "bounty."  The scandal is there was no reaction or retaliation from the Commander-in-Chief*. In schoolyard parlance, Putin knocked the board off Orange Satan's shoulder, and he slunk away to get into a Twitter spat with a pack of mean middle school students. Twitter saw hacks Elon Musk, Barack Obama, Joe Biden (hopefully, the successor of Satan), and a lot of other prominent American accounts for a bitcoin scam. I can't imagine this wasn't Putin: he has no push back to any actions in the world he's taking. (Noticeably, Tangerine Nit Twit's account was fine.) Russians are also interested in our vaccine information, because a recovering America during a pandemic to them, is a threat.

Deafening silence (still) from a law-and-order president* and his politically compromised party complicit with a hostile foreign power.

* Putin's puppet, if you didn't already know.

Realize: This republic's unraveling has been an ongoing project. It was held together by spit, glue and duct tape. Every step forward by the marginalized has always experienced backlash. Corey Robin in "The Reactionary Mind: Conservatism from Edmund Burke to Sarah Palin" states: Conservatism is the theoretical voice of this animus against the agency of the subordinate classes, i.e. people get pissed off about getting pissed on, and the ones over them calling it rain. This spawns Civil Rights, Women's Rights, LGBT rights movements, because a few of us actually read The Constitution. Jimmy Carter was our first openly evangelical president, and supported by none other than types like Michelle Bachmann. However, he ran afoul when he tried to get Bob Jones University to follow the law, and not be so racist with miscegenation (a fancy word for no interracial dating). Hopping on the abortion bandwagon was an easy dodge that I don't think they ever meant to win, as Corey Robin noted, the war against an enemy was the most important thing. This led them to their first sale of a piece of their souls to a B-movie actor, Ronald Reagan.

Reagan knowingly started his campaign within meters of the murders of Chaney, Goodman and Schwerner in Philadelphia, Mississippi. This was genteel wink-and-nod politics, giving plausible denial to moderate whites and black republicans that could then both deny the subtle racism directly before them. Since Charlottesville and before it when IT descended that escalator in Trump tower, it's been a foghorn, and only a blind/deaf/dumb man could miss his self-admittance the alt-right, Neo Nazis and KKK can recognize. Every tax cut, then and since Reagan, has been a damned lie of trickle down; pissing on us, and still telling us it's rain. Hell, why change the shtick if it's still working after forty years? It's not a huge stretch from a B-movie actor to a reality show nincompoop.

I purchased Too Much and Never Enough: How My Family Created the World’s Most Dangerous Man, by Dr. Mary L. Trump, feeling better contributing to its rise on the New York Times Bestseller List than John Bolton's (I canceled it when I found out he influenced the disbanding of the pandemic response team). Not that there wasn't a cottage industry that's used their access to this criminal to like Bolton, cash-in. Dr. Trump is a clinical psychiatrist specializing in psychopathy and sociopathy. She is also, by her last name: his niece. She is similar (to me) Marilyn Munster - "plain" by Munster norms - but normal to everyone else viewing the sitcom. In it, the mansion that Fred Trump met out his sociopathic abuse that produced our current president* was simply referred to as "The House."

The "Fall of the House of Usher" is a classic Gothic short story by the master of the macabre, Edgar Allen Poe. In it, the unnamed narrator makes the dysfunction of the Usher family - only one heir per generation - and the house itself one in the same. There is a suggestion this genetic problem might be the result of incest, since they only manage to have one heir per generation.

The narrator's friend Roderick buries his twin sister, Madeline after suffering catalepsy, defined as the loss of control of one’s limbs. Dictionary.com says "a physical condition usually associated with catatonic schizophrenia, characterized by suspension of sensation, muscular rigidity, fixity of posture, and often by loss of contact with environment." Poe sure could pick the sickness!

Madeline "dies" (even before comics, there's a loophole), buried; only to emerge bloodied from the grave she escaped and attacks her brother (who wouldn't, buried alive?). She dies from her wounds, Roderick dies from apparent cardiac arrest and the house poetically collapses with the death of both heirs as the narrator sprints.

Brian Kemp is suing the city of Atlanta, its mayor and other municipalities to stop them from wearing masks, so...he can spread Coronavirus more efficiently? It's about as sensible as hocking Goya beans as refrigerator trucks and bodies are piling up.

I voted for the smart woman last time. I'm voting for the sane candidate this time as well: he models wearing a mask. I will crawl over broken glass, swim molten lava; wrestle man-eating crocodiles to end this dystopian nightmare. It's way past if we "love" Joe Biden: we need to overwhelm the cheating, voter suppression, the Russians hacking/disinformation and affect repairs to the framework of a crumbling republic.

However: If this house disintegrates, this narrator's passport is current.

Why cannot we write the entire 24 volumes of the Encyclopedia Britannica on the head of a pin? Dr. Richard P. Feynman, "There's Plenty of Room at the Bottom," said to be the seminal talk that started the concept of atomic-level engineering, soon known as nanotechnology, (named by Professor Norio Taniguchi, 1974, of the Tokyo Science University).

The intricate arrangement of base pairs in our DNA encodes just about everything about us. Now, DNA contains the entirety of “The Wonderful Wizard of Oz” as well.

A team of University of Texas Austin scientists just vastly improved the storage capacity of DNA and managed to encode the entire novel — translated into the geek-friendly language of Esperanto — in a double strand of DNA far more efficiently than has been done before. DNA storage isn’t new, but this work could help finally make it practical.

Big tech companies like Microsoft are already exploring DNA-storage technology, as the biomolecule can encode several orders of magnitude more information per unit volume than a hard drive. But DNA is particularly error-prone. It can easily be damaged and erase whatever’s stored on it.

“The key breakthrough is an encoding algorithm that allows accurate retrieval of the information even when the DNA strands are partially damaged during storage,” molecular biologist Ilya Finkelstein said in a UT Austin press release.
