Scientists just captured the first-ever photo of the phenomenon dubbed "spooky action at a distance" by Albert Einstein. That phenomenon, called quantum entanglement, describes a situation where particles can remain connected such that the physical properties of one will affect the other, no matter the distance (even miles) between them.
Einstein hated the idea, since it violated classical descriptions of the world. So he proposed one way that entanglement could coexist with classical physics — if there existed an unknown, "hidden" variable that acted as a messenger between the pair of entangled particles, keeping their fates entwined. [18 Times Quantum Particles Blew Our Minds in 2018]
There was just one problem: There was no way to test whether Einstein's view — or the stranger alternative, in which particles "communicate" faster than the speed of light and particles have no objective state until they are observed — was true. Finally, in the 1960s, physicist Sir John Bell came up with a test that disproves the existence of these hidden variables — which would mean that the quantum world is extremely weird.
This is "the pivotal test of quantum entanglement," said senior author Miles Padgett, who holds the Kelvin Chair of Natural Philosophy and is a professor of physics and astronomy at the University of Glasgow in Scotland. Though people have been using quantum entanglement and Bell's inequalities in applications such as quantum computing and cryptography, "this is the first time anyone has used a camera to confirm [it]."
To take the photo, Padgett and his team first had to entangle photons, or light particles, using a tried-and-true method. They hit a crystal with an ultraviolet (UV) laser, and some of those photons from the laser broke apart into two photons. "Due to conservation of both energy and momentum, each resulting pair [of] photons are entangled," Padgett said.
APOLLO 11 Results from the Apollo 11 mission established key paradigms of lunar and planetary science. After a harrowing descent to the surface, Armstrong set the Eagle down on the cratered basaltic plains of Mare Tranquillitatis. Extravehicular activity was brief—just two and a half hours during that first mission—and included setting up surface experiments and exploring a small cluster of craters near the lunar module and Little West Crater some 60 meters away, as shown in figure 1. Aldrin’s iconic Apollo 11 bootprint photo revealed much about the lunar soil, including its fine-grained nature, its cohesiveness, and its ability to pack tightly together.

On 20 July 1969, Apollo 11 astronauts Neil Armstrong and Edwin “Buzz” Aldrin landed on the Moon while Michael Collins orbited in the command module Columbia. “Tranquility Base here. The Eagle has landed”became one of the most iconic statements of the Apollo experience and set the stage for five additional Apollo landings.
Each of the Apollo missions explored carefully selected landing sites and conducted a variety of experiments to probe the lunar interior and measure the solar wind. Well-trained astronauts made geologic observations and collected samples of rock and regolith, the impact-generated layer of debris that composes the lunar surface. Over a half century of study, the samples have revealed abundant information not only about the Moon’s origin and history but also about the workings of our solar system.

"Diversity is our strength, unity is our power." Speaker of the House Nancy Pelosi
U.S. innovation has long drawn inspiration from a mix of scientific disciplines, academic institutions, research laboratories and industries, yet the scientific enterprise’s workforce lacks diversity of another sort, according to testimony before a House panel on May 9.
In remarks delivered to the House Committee on Science, Space and Technology, Shirley Malcom, a senior adviser at the American Association for the Advancement of Science, said the growing need for a workforce capable of delivering future innovations and meeting the world’s challenges will require “expanding the pool of talent, tapping into the vast well of women, minorities, racial and ethnic, and people with disabilities currently underrepresented in STEM,” the fields of science, technology, engineering and mathematics.
The perspective delivered by Malcom, who also serves as director of AAAS’ STEM Equity Achievement or SEA Change initiative, were echoed by Rep. Eddie Bernice Johnson, D-Texas, chairwoman of the House Science, Space and Technology Committee, as well as by each of the four other panelists who joined Malcom in addressing the committee.
“As the rest of the country becomes more diverse, the STEM workforce has been slow to respond,” said Johnson. “In addition, I have watched with dismay for decades as women have made too few gains in the STEM workforce.”
The "STEM Opportunities Act of 2019, a bill that would require more comprehensive demographic data to be collected on recipients of federal research awards and STEM faculty at universities to help identify and reduce barriers that prevent women and underrepresented groups from entering and advancing in STEM."
The caveat: the House bill will likely stall and die in the Senate if not outright vetoed by a recalcitrant, science-phobic administration basing its next reflexive move on what the previous black president favored. It is the insistence on being the center of the story forever; the hero of the plot. It allows a growing inequality based on zip codes, city funding, cultural maturity and opportunity. Most of the aforementioned zip codes will be urban, but a lot of them rural, currently undergoing an opioid crisis and economic opportunities excavated by bad trade policies. Their being over "colored others" is a warped and sadistic feel-good measure but not a solution - similar to the sentiments expressed with a "send her back" chant at a North Carolina Klan rally Wednesday. It is a de facto redlining scheme to keep the country gerrymandered on the status quo of visual differences reinforced by propagandized compulsory education with schlock creation science; entertainment options meant to numb us and media to reinforce our biases. It is not a path forward to a mythologized lost "greatness." It is proto fascism.
"You may shoot me with your words,
You may cut me with your eyes,
You may kill me with your hatefulness,
But still, like air, I'll rise."
Representative Ilhan Omar quoting Dr. Maya Angelou on Twitter
It is an open invitation for China to take advantage of this blatant racism and ignorance, powering ahead of us to become the world's dominate superpower. Once our lofty perch among nations is lost, we will likely not recover it. We will be a byword, a proverb and in the inimitable words of our current juvenile chief executive "they are [and will likely be] laughing at us"; that throwaway line against his ardent foe that made him sad at the 2011 White House Correspondents Dinner, prophetically projection.

The first time I ran into the notion of the moon landing being "faked," a young coworker showed me a grainy amateurish video on YouTube. I encountered it with a co-vendor at the IBM research facility I supported. To neither, both younger than me, did it matter that "I was there" and they weren't on the planet yet. Evidence and eye witness testimony did not move them from their stances.
Neil Armstrong thought he had a 50–50 shot at pulling it off. "There are so many unknowns," the first man to set foot on the moon said in a 2011 interview with an Australian accounting firm. “There was a big chance that there was something in there we didn’t understand properly and we [would have] to abort and come back to Earth without landing.” That he, Edwin “Buzz” Aldrin and Michael Collins—with the help of thousands of NASA engineers, scientists and mission controllers on Earth—did pull off a moon landing remains one of humanity's most incredible achievements.
Consider that 50 years ago this month a 36-story-tall Saturn V rocket weighing as much as 400 elephants climbed away from Earth atop an explosion more powerful than the output of 85 Hoover Dams. Once in space, the astronauts escaped Earth orbit, traveled to lunar orbit, then undocked part of their spacecraft and steered it down for a soft impact on an alien land. Perhaps even more impressive, after taking a walk around, they climbed back in their lunar lander, launched off the surface of another planetary body (another first), rejoined the command module orbiting roughly 60 miles above the lunar surface, and then flew back to Earth, splashing down safely in the Pacific Ocean two days later. 
The spin offs from the space industry technologically benefited America. Not since the king cotton era (fueled by the free, uncompensated slave labor of my ancestors) had the United States enjoyed such dominance in production, productivity and economic expansion. It would go on for decades, many young people inspired by NASA, Star Trek reruns and conventions to pursue STEM careers out of a passion for exploration, and birthing a more egalitarian society post previous sectarian divisions.
Exactly 50 years ago today, a Saturn V rocket launched from Kennedy Space Center carrying Neil Armstrong, Buzz Aldrin, and Michael Collins to the Moon. Four days later, Armstrong and Aldrin would land on the Moon and inspire a generation of young people to become scientists, engineers, and mathematicians.
The Apollo program's effect of inspiring America's children to pursue careers in STEM fields is one of the most powerful lasting legacies of the Moon race. Unfortunately, this effect seems to be coming to an end.
On the eve of the Apollo 11 anniversary, LEGO asked The Harris Poll to survey a total of 3,000 children in the United States, China, and the United Kingdom about their attitudes toward and knowledge of space. The results reveal that, at least for Western countries, kids today are more interested in YouTube than spaceflight. 
Entertainment and ambition looked upward: the notion of a three nacelle starship with a saucer section that could travel impossible speeds fueled imaginations. The notion of defying relativistic time dilation, traversing vast distances in human lifetimes propelled many of us into STEM to “do our parts” in getting at least close to this lofty goal. A fifth or tenth the speed of light to Proxima Centauri would achieve that aim. Any higher level physics class disabused us of attaining “warp speed,” but we could see the technological benefit and spin off of assisting in things that would promote the “Common Good” here on Terra Firma.
We did not count on the divorce of productivity and cost of living wages, stagnant since the 1970s. We did not count on conspiracy theorists masking themselves as serious news pundits and influencing more than clicks or product purchases from their sites. We did not count on the rapidly increasing (and encouraged) income disparity. We did not count on politicians bought by wealthy families and corporations whose only about getting wealthier and more powerful in our lives. We did not count on science denial, climate or otherwise. Such a dysfunctional dystopia depends on selfies, self-centered attitudes and distractions, like supercomputers in our hip pockets sharing our suppers; websites that reinforce our views and cute cat videos. And we did not count on the cultural division encouraged by authoritarians the world over as their best means of controlling the masses.
It is in such a world young people would rather be YouTube personalities than starship captains.
My previous, gob-smacking encounters with my younger coworkers are now explained.

Cell reproduction, disease detection and semiconductor optimization are just some of the areas of research that have exploited the atomic force microscope. First invented by Calvin Quate, Gerd Binnig and Christoph Gerber in the mid 1980s, atomic force microscopy (AFM) brought the atomic resolution recently achieved by the scanning tunnelling microscope to non-conducting samples, and helped to catalyse the avalanche of science and technology based on nanostructures that now permeates all aspects of modern life from smartphones to tennis rackets. On 6 July 2019 Calvin Quate died aged 95 at his home in Menlo Park, California.
Long before the development of AFM, Quate’s research had made waves in microscopy. 1978 had seen the announcement of the scanning acoustic microscope, which achieved the sensitivity of optical microscopy but probed samples so softly that it could image the interiors of living cells without damaging them. The technique uses high frequency sound waves in place of light, which penetrate deep into structures to image internal structures non-destructively. It is widely used in quality control of electronic component assembly among other applications such as printed circuit boards and medical products.
If the video embed invokes the Bard ("what's past is prologue" - William Shakespeare) his racism came from his environment, not reruns of "All in the Family" with Archie Bunker.
He was a racist when he descended the escalator at Trump Tower, railing against Mexicans as drug dealers and rapist and Muslims as terrorist.
He was a racist as he made "other" the first African American President of the United States in his swiped-from-Orly-Taitz birther campaign that put him in the Oval Office.
He was a racist when he took a full-page ad out in the NY Times calling for at the time a return of the death penalty for the Central Park Five. Even after DNA evidence exonerated them and the actual rapist confessed, he still won't admit his error.
He was a racist when the NIXON administration's justice department came after him and his father in the 1970s for discriminating against African Americans and Puerto Ricans in their rental properties in New York.
I recall the jarring sight of the Robert E. Lee Battle Flag (NOT the flag of the Confederacy as it is misidentified by the lazy) in a village in Wappingers Falls, NY about 80 miles north of Manhattan. The "stars and bars" were flying high in Boston, Massachusetts as I took a class in Implant Engineering in 2016 at the onset of this poorly-scripted, reality-TV slow-rolling nightmare.
First Nation Peoples who speak native tongues are told to "go back where you came from" when they were here before Europeans.
African Americans are told to "go back where we came from" as IF leaping on a slave ship sir named "The Good Ship Jesus" packed like sardines, suffering cholera, diarrhea, dysentery and death; the survivors separated, raped and beaten worse than cattle did it all for a LARK!
Hispanics/Latinos are told to "go back where they came from" when Texas, New Mexico, Arizona, Las Vegas and California USED TO BE Mexico. The Alamo - so "bravely fought" for Texas freedom - was started because the Mexicans would not agree to continue slavery!
This nation is a sham, a facade: a fake! It's told itself a line of bullshit so long, it's become accepted history instead of the propaganda used by a well-moneyed oligarchy to maintain control of the masses.
They WON'T do reparations because this "system" needs pariahs. Without them, the whole thing crumbles like a house of cards: African Americans, First Nation, Hispanic/Latinos, LGBT; Women. It needs someone to be under a stamping boot:
"If you want a vision of the future, imagine a boot stamping on a human face - forever." O'Brien to Winston in "1984."
It's why the struggle isn't left-right as Robert Reich has stated, but between democracy and oligarchy, who have likely gotten plenty tired of democratic freedoms interfering with the Ayan Rand, Atlas Shrugged invisible hand of the "free market."
Keeping poor whites against people of color is the easiest way for them to keep control and not have accountability for their avarice and nihilism.
Naturalized or birth: we're the American melting pot. We're all from here.
"For years, even before mounting a formal bid for the presidency, Trump regaled television news audiences with racist conspiracy theories about former president Barack Obama. He pledged to send investigators out to prove the nation’s 44th president was not born in the United States. He later derided immigrants from Haiti, El Salvador, and African countries, calling those foreign nations “shit hole countries.” He once said immigrants from Haiti all “have AIDS” and that Nigerian immigrants would never “go back to their huts.”
In Trump’s mind, a judge’s Mexican heritage made him incapable of ruling fairly in a civil fraud case against one of his companies and he believes “laziness is a trait in blacks.” Trump, whose real estate company was sued for housing discrimination in the 1970s, went on to place a full-page ad in the New York Times calling for the execution of five innocent black teenagers. Even after the Central Park Five were exonerated, he refused to take it back. After Heather Heyer was murdered in Charlottesville, Virginia, amid a white supremacist protest, he lamented the there were “some very fine people” on “both sides.”
Trump is not a fine person. His words Sunday were not racially “charged,” “fueled,” or “tinged.” They were unapologetically racist.
After many weeks of running experiments, parsing data and writing preliminary conclusions, I had to stand before my committee: my advisor (chemist) and my nano physics professor, the department chair (mechanical engineering) and defend my research. In hindsight, it was the committee on steroids.
I bought coffee and donuts; water for the committee as is the tradition. That exposed me to 95 degree heat and North Carolina humidity. I ended up defending without my suit jacket.
There is the public defense part where you get questions from either the panel or the audience. Then the grueling begins when the audience is encouraged to leave and you are alone with your committee.
I was challenged on my understanding of the data, not in an accusatory way but to foster a better rewrite when I turn in my written product to the Graduate College. Those are due next Wednesday. I should be able to fulfill that request on review with my advisor. The committee also suggested further experiments I could do to verify what I thought I was seeing. After an intense 40 minutes of questioning, I was asked to leave as the committee conferred. For what seemed like an eternity, my advisor came out and shook my hand: "congratulations." I then went in to the committee to get their final suggestions and signatures for completing the process.
I am also moving...within Greensboro mind you, but to a house we own outright versus a rental apartment we don't.
It reminded me of my father proudly burning the last payment record as we owned our modest home - two bedrooms, one bath and less than a thousand square feet - in East Winston-Salem off Cleveland Avenue.
For the move, I had to parse through memorabilia that traveled with us from Texas to New York to North Carolina. It was time to make some decisions.
I found the program and invitation to my mother's graduation from Practical Nursing School in Philadelphia, Pennsylvania. I imagined the trip for her and my father probably took a lot of back roads and the Green Book during that time period.
I found my parents' invitations sent for my high school graduation as well as my acceptance letter saying I had been accepted to North Carolina A&T State University for the fall semester, 1980. I found my first karate promotion certificates from Dr. Casterlow as part of the A&T Dojo.
I found a short story my father kept I had written for catharsis called "The Decision." It was when Pop left it to me to decide the fate of my dog, a Cocker Spaniel named Fala, named after FDR's dog. He was aged, tired and had stopped eating. The gist of the story was "sometimes as a man, you have to make difficult decisions." I was twelve. I didn't own a dog again until I was an adult with sons of my own. Parting with each four-legged friend has never gotten easier.
I found a lot of family photos that will go in albums and on a flash drive soon.
I also found the corroborating evidence I had read on History.com: the GI Bill like the New Deal before it was discriminatory to African Americans. My father passed a college entrance exam with only a sixth grade education formally, due to the fact he and my uncle Moses, Jr. went to work for my grandmother to help out the household. The GI Bill for white soldiers and sailors paid for a college education and loans encouraging home ownership, building a wealth gap that has persisted for generations. Many white service members went on to become professionals and professors. The GI Bill for my father and his fellow WWII veterans of color only covered vocational training, like barber school. So that's what he learned. Pop often cut my hair in the kitchen of our home in a segregated neighborhood crafted by redlining legislation. He faced the indignities of working for a textile company - routinely getting passed over for promotions and getting called "boy" or n-word then his name. He smoked in a chair in his bedroom before he engaged with the family every evening after work. That was his way of coping. It eventually led to lung cancer, the contributing cause of his death.
I sadly had to throw away his literature books he bought for me: I read The Iliad and the Odyssey from that collection. I read snippets of Milton and I meant to read Thomas Paine. They alas were molded and mildewed; unrecoverable. I plan to replace the collection once we're settled in.
Announcing the good news on Facebook numbered in the thousands on the Kappa Alpha Psi page; hundreds on my main feed. It was good to see others, near and far, celebrate this achievement with me.
I passed my Masters Thesis defense.
I like to think I redeemed my father's dreams as well.

I was so incensed Wednesday that a sitting president would accept help from a hostile foreign government if it helped him win, I penned a 5-page letter to Speaker of the House of Representatives Nancy Pelosi, six pages with references I cited.
I then emailed it (the memory cut off six of my eleven references). I posted it on Scribd.com. I then tweeted it to her @SpeakerPelosi. I snail mailed it from the local Post Office and bought Marvin Gaye stamps, finally. Tracking has her office getting it on Tuesday of next week.
The grave disappointment came when I called her number in DC: 202-225-4965. You can try, but you're given three options:
You could leave a message to "voice your opinion, or pass on a personal story," except her mailbox is full. You're given the option to dial "0" and "someone will assist you." After a LONG radio silence, the call was summarily dropped.
This gives you instructions of how to email the Speaker at Speaker.gov/contact. See first statement, second paragraph above.
This gives you a guide to go to Speaker.gov to view her latest policy statements as well as her Twitter feed. See first sentence, second paragraph for which I would have had to GO to her website to do in the first place!
My letter, emailed, tweeted and snail mailed is at the link below. Depending on the platform, it either appears as an embed or a link.Each version will likely be read by a staffer and responded to with a form letter, restating the positions she's taken publicly and stamped with her mimeographed signature. Perhaps we've always been like this: instead of a "separation of powers," there's a separation of the people from the representatives we elect to power, No matter the outcome of the 2020 election, Nancy Pelosi will still be, from her service since the first wave of the "year of the woman" that brought her to prominence, quite wealthy - her children and grandchildren in a class mine probably will never enjoy. This is the kind of result that depresses voter turnout, as votes are a "hope" for a better future as well as an expression of desire by the governed. It is not surprising we are not being listened to, that the "mailbox is full."
And I sincerely hope, in my lamentations regarding this post, that I am horribly wrong.
The sea sloshing beneath the icy surface of Jupiter’s moon Europa just might be the best incubator for extraterrestrial life in our solar system. And yet it is concealed by the moon’s frozen outer shell—presenting a challenge for astrobiologists who would love nothing more than to peer inside. Luckily they can catch a partial glimpse by analyzing the flavor of the surface. And the results are salty.
A new study published this week in Science Advances suggests that sodium chloride—the stuff of table salt—exists on Europa’s surface. Because the exterior is essentially formed from frozen seawater, the finding suggests that Europa’s hidden sea is drenched in table salt—a crucial fact for constraining the possibilities for life on the alien world.
Not that scientists have tasted a slice of the distant moon. To analyze Europa’s composition, astronomers study the light emanating from its surface, splitting it into a rainbow-like spectrum to search for any telltale absorption or emission lines that reveal the world’s chemistry. There is just one problem: Ordinary table salt is white and thus gives off a featureless spectrum. But harsh radiation—which exists at Europa’s surface in abundance—just might add a dash of color. That much was realized in 2015 when two NASA planetary scientists Kevin Hand and Robert Carlson published a study suggesting the yellowish-brown gunk on Europa might be table salt baked by radiation. To reach that conclusion, Hand and Carlson re-created the conditions on Europa within vacuum chambers—or as Hand calls them, “stainless steel shiny objects that are humming and whizzing.” Next, they placed table salt into those chambers, lowered the pressures and temperatures to simulate Europa’s surface, and blasted the samples with an electron gun to simulate the intense radiation.

We all know and love the Higgs boson — which to physicists' chagrin has been mistakenly tagged in the media as the "God particle" — a subatomic particle first spotted in the Large Hadron Collider (LHC) back in 2012. That particle is a piece of a field that permeates all of space-time; it interacts with many particles, like electrons and quarks, providing those particles with mass, which is pretty cool.
But the Higgs that we spotted was surprisingly lightweight. According to our best estimates, it should have been a lot heavier. This opens up an interesting question: Sure, we spotted a Higgs boson, but was that the only Higgs boson? Are there more floating around out there doing their own things?

The simplest home medical tests might look like a deck of various silicon chips coated in special film, one that could detect drugs in the blood, another for proteins in the urine indicating infection, another for bacteria in water and the like. Add the bodily fluid you want to test, take a picture with your smart phone, and a special app lets you know if there's a problem or not.
That's what electrical engineer Sharon Weiss, Cornelius Vanderbilt Professor of Engineering at Vanderbilt University, and her students developed in her lab, combining their research on low-cost, nanostructured thin films with a device most American adults already own. "The novelty lies in the simplicity of the basic idea, and the only costly component is the smart phone," Weiss said.
"Most people are familiar with silicon as being the material inside your computer, but it has endless uses," she said. "With our nanoscale porous silicon, we've created these nanoscale holes that are a thousand times smaller than your hair. Those selectively capture molecules when pre-treated with the appropriate surface coating, darkening the silicon, which the app detects."

By confining single ions of aluminum and magnesium in an electric trap, cooling them to near absolute zero and probing them with laser beams, physicists at the National Institute of Standards and Technology (NIST) in Boulder, Colorado have built what is in effect the world’s most accurate clock. Having fractionally improved on the performance of another clock at NIST, the researchers have shown that their device would neither gain nor lose a second in 33 billion years (if it could run for that long). Such accurate timekeeping, they say, could boost geodesy and lead to new insights in fundamental physics.
The clocks that currently underpin atomic time rely on precisely measuring the frequency of microwaves emitted during a specific transition in cesium atoms. But such devices are limited by the relatively low frequency of that radiation. To keep time even more accurately, and eventually introduce a new definition of the second, physicists are developing clocks based on higher-frequency optical transitions.
The latest work at NIST features what is known as a quantum-logic clock. Built by Samuel Brewer and colleagues, it uses a positive ion of aluminum-27 as its timekeeper. When exposed to ultraviolet laser light at wavelength 267 nm, the ion undergoes a transition with a very narrow line width – making its frequency very well defined. What is more, that transition is largely immune to sources of external noise – such as blackbody radiation – that in other types of optical clock shift the frequency away from its true value.
A magnesium-25 ion is used to cool the aluminum down to the very low temperatures needed to minimize thermal noise. Cooling involves the absorption of photons at another specific frequency, but practical limitations mean that this cannot be done using the aluminum itself. This is because the required frequency in is too high for any practical laser. By entangling the two ions, the magnesium cools the aluminum via Coulomb interactions. This process also allows the quantum state of the aluminum ion to be read-out following exposure to the clock laser.

The Power of Positive Thinking is a self-help book by Norman Vincent Peale, originally published in 1952. It makes use of positive case histories and practical instructions to propose the method of positive thinking. Peale's work describes how to achieve a permanent and optimistic attitude through unending positive conscious thought, usually through affirmations or visualizations. Peale writes that such techniques will give the reader a higher satisfaction and quality of life. Though negatively reviewed by scholars and health experts, The Power of Positive Thinking became popular in public opinion when first published and continues in popularity today.

Come 1953, this legal prodigy was named McCarthy’s boy-wonder chief counsel, and the news photos told the tale: the sharp-faced, heavy-lidded 26-year-old with cherubic cheeks, whispering intimately into the ear of the bloated McCarthy. Cohn’s special skill as the senator’s henchman was character assassination. Indeed, after testifying in front of him, an engineer with the Voice of America radio news service committed suicide. Cohn never showed a shred of remorse.
You knew when you were in Cohn’s presence you were in the presence of pure evil,” said lawyer Victor A. Kovner, who had known him for years. Cohn’s power derived largely from his ability to scare potential adversaries with hollow threats and spurious lawsuits. And the fee he demanded for his services? Ironclad loyalty.
For author Sam Roberts, the essence of Cohn’s influence on Trump was the triad: “Roy was a master of situational immorality . . . . He worked with a three-dimensional strategy, which was: 1. Never settle, never surrender. 2. Counter-attack, counter-sue immediately. 3. No matter what happens, no matter how deeply into the muck you get, claim victory and never admit defeat.” As columnist Liz Smith once observed, “Donald lost his moral compass when he made an alliance with Roy Cohn.”
Yesterday was the 75th anniversary of the Normandy invasion. Our national embarrassment managed to be an embarrassment on the world stage. What I thought was missing was any discussion of the African American soldiers and sailors that sacrificed for this nation during that war, specifically to show their worth as citizens and as human beings. We've fought in every war this nation has prosecuted in its history, yet the descendants of the African Diaspora are still fighting for their rights in this country. I found the absence of any discussion ironic and disturbing under current circumstances.
I cannot attest Donald Trump ever HAD a moral compass to lose. His father was arrested at a Klan rally in NY city, 1927; he and his father discriminated against people of color in their rental apartment buildings; the Central Park 5, for which he refuses to apologize: Charlottesville. He has divided the nation with a racist jigsaw. He's more Darth Vader to Emperor Palpatine, Darth Maul to Darth Sidious; under demon to Lucifer. The degree of evil doesn't matter: it's just evil.
Norman Vincent Peale's philosophy has had it's supporters and critics, both in science and clergy. Marble Church - the spiritual descendant of Peale's philosophy - is claimed by the Trumps, the pathological liar referring in the past to Peale as his pastor. A lot of Norman Vincent Peale's method have other names: "name it and claim it"; "new thought" and "positive mental attitude." It's the kind of thing a sales representative reads to pump up their egos to press on. It is the kind of philosophy an urban youth might use to motivate their enthusiasm to overcome their economic circumstances. It is ripe for warping by a demagogue.
Chris Rodda responded to the pseudo-historical polemics published by David Barton, a "historian" who possesses no PhD in the field as most historians do. He is the go-to "expert" for talk show hosts like Glenn Beck et al to tell their audiences kind fables that comfort their angst regarding the changing demographics of America. He tries to rewrite actual history to fulfill the fables of a group he hucksters, where "facts are stubborn things; and whatever may be our wishes, our inclinations, or the dictates of our passions, they cannot alter the state of facts and evidence."John Adams But those "stubborn things" are of no consequence to Christian fascists.
The only way to see the Venn diagram merger of religion and pathological lying is the nexus formed in the mind of an addled man between these two men: Norman Vincent Peale and Roy Cohn, Yin and Yang; light and darkness. A brain that can only hold onto "Two Corinthians" as a biblical verse he MIGHT have heard in the scant attendance he's logged at the Crystal Cathedral, for his thus far dedicated following, his voluminous tableau of lies doesn't matter. He fulfills what Christian nationalists cum evangelicals and white nationalists the world over want more than eternal salvation - power. The ends justify the means: voter suppression, resistance to "advise and consent" Merrick Garland's appointment to the Supreme Court (a stolen seat); Russian interference so long as white privilege, white supremacy - white power continues to rule. Our bent away from democratic norms predates the Russian attack on our elections in 2016.
The soul of a republic is apparently a small price to pay for this idolatry. It will be the death of our country...and the world.
Two views of galaxy Markarian 1216. The red image on the left shows X-ray observations conducted by NASA's Chandra X-Ray Observatory, and the yellowish image on the right is composed of optical observations taken by the Hubble Space Telescope. The brighter colors at the center of the Chandra image represent the increased density of hot gas in the galaxy's core.

X-ray observations of a peculiar galaxy deep within the constellation Hydra (the Sea Serpent) have revealed more dark matter at its core than expected.
The galaxy is almost as old as the universe itself, representatives from NASA's Chandra X-Ray Observatory said in a statement published Monday (June 3). This celestial body, Markarian 1216, went through a different evolution than typical galaxies and is home to stars that are within 10% of the age of the universe.
To study the dark matter within this compact, elliptically shaped galaxy about 295 million light- years from Earth, researchers conducted new observations with the Chandra spacecraft. Markarian 1216 is packed with more dark matter in its core than researchers expected, according to their findings published June 1.

The main problem I see: the seeking of public funding for a Utopian project could easily benefit the well-healed instead of the needy many. It would be cynical to use government funds, first gaining public support, then diverting funds but not unlikely. The wrong-type of people being preserved after the earth is ravaged by our environmental hubris is the main plot of the movie Elysium.
Humans have a long history of living on water. Our water homes span the fishing villages in Southeast Asia, Peru and Bolivia to modern floating homes in Vancouver and Amsterdam. As our cities grapple with overcrowding and undesirable living situations, the ocean remains a potential frontier for sophisticated water-based communities.
The former tourism minister of French Polynesia, Marc Collins Chen, and architecture studio BIG advanced the proposal. Chen is involved with the Seasteading Institute, which is seeking to develop autonomous city-states floating in the shallow waters of “host nations”.
While this latest proposal has gained UN attention, it is an old idea we have repeatedly returned to over the past 70 years with little success. In fact, the Oceanix City proposal has not reached the same level of technical sophistication as previous models.
