Micro-Gami...

Image Source: Origami Resource Center
Topics: Graphene, Nanotechnology, NEMS, Robotics

Thirty years ago, a professor in Japan folded an origami crane smaller than a pinhead. Peering through a microscope, he used a sewing needle to carefully crimp the paper.

Now researchers at Cornell University in Ithaca, New York, have gone one step further, creating origami about the size of a red blood cell. Too small for human hands, their origami folds itself. This new take on an old tradition is made not from paper, but from sheets of glass and carbon only a few atoms thick.

“It’s the world’s thinnest origami … comparable in size to a biological microorganism,” said Marc Miskin, a postdoctoral associate in the laboratory of applied physicist Itai Cohen at Cornell. He described the new research in a March 14 talk at an American Physical Society meeting in New Orleans.

The simple shapes formed by the micro-gami, such as cubes and pyramids, lack the grace and sophistication of a bird. But they could be a step toward miniature machines that fold themselves up into packages small enough to be injected into the body.

A comet whose identity took nearly 100 years to pin down is making its closest approach to Earth today (April 1), just in time for April Fools' Day, but this is no cosmic prank. It is the comet's closest Earth encounter in more than 50 years, and maybe more than a century, NASA officials said.

Comet 41P/Tuttle-Giacobini-Kresák is named after its three discoverers —Horace Tuttle, Michael Giacobini and L'ubor Kresák — who tracked the comet separately over nearly a century.

Tuttle first spotted the comet in 1858, when 41P was first identified as a sun-orbiting (or periodic) comet, NASA officials wrote, citing the Cometagraphy website by Gary Kronk. But the length of the comet's orbit was unknown at the time. Comet 41P was rediscovered in 1907 by Giacobini, but still not tied to the object seen by Tuttle in 1858.

Another astronomer, Andrew Crommelin, later linked the two observations by Tuttle and Giacobini and predicted Comet 41P would return in 1928 and 1934, but the object went unseen, according to Cometography. It wasn't until 1951, when Kresák spotted the comet and linked it with the earlier observations, that Comet 41P identity was officially pinned down.

The Shattering...

From FBI.gov:

COINTELPRO The FBI began COINTELPRO—short for Counterintelligence Program—in 1956 to disrupt the activities of the Communist Party of the United States. In the 1960s, it was expanded to include a number of other domestic groups, such as the Ku Klux Klan, the Socialist Workers Party, and the Black Panther Party. All COINTELPRO operations were ended in 1971. Although limited in scope (about two-tenths of one percent of the FBI’s workload over a 15-year period), COINTELPRO was later rightfully criticized by Congress and the American people for abridging first amendment rights and for other reasons.

The John Birch Society (TIME):

Had his story ended when he retired as a candy-maker, Robert Welch Jr. might have made his mark on history as the father of the Sugar Daddy, Sugar Babies and Junior Mints. But Welch, whose shrewd leadership helped grow his brother’s Massachusetts candy business a hundred-fold from 1935 to 1956, shifted his aim from caramels to communists.

On this day, Dec. 9, in 1958, Welch — then retired from the candy business — founded the ultraconservative John Birch Society along with 11 like-minded “Americanists,” as they referred to themselves. Their goal was to expose and eradicate the growing leftist threat in America, which they believed to be 40 to 60 percent communist-controlled, according to a 1961 TIME report. Members of the John Birch Society saw communists wherever they looked, from the Oval Office of Dwight Eisenhower (“A conscious agent of the communist conspiracy,” per Welch) to the Bay of Pigs (“a theatrical performance jointly sponsored by Castro and ‘his friends in the U.S. Government’ in order to strengthen the communist hold on Cuba,” as paraphrased in TIME).

The "growing leftist threat"...

COINTELPRO was the government version of John Birch. Though the write up eludes to other groups the FBI had under surveillance, it was felt by African American communities the most, specifically the Black Panther Party; the Nation of Islam; the Southern Christian Leadership Conference, etc. The approval of the Communist Manifesto by the likes of Huey Newton and the unrest in the streets likely gave J. Edgar Hoover much alarm. It couldn't have been the treatment of American citizens by their fellow citizens and de facto/de jure Jim Crow laws against them. It was easy to wrap surveillance in the flag and patriotism to hide the racist overtones of the act.
The "growing leftist threat"...

If the Birch philosophy sounds familiar, it's because one of its ardent members was the famous Koch Brother's father, Frank Koch, an MIT oil engineer. He infamously built oil refineries for Nazi Germany and did a considerable amount of business with the Russians.

The Nazis... the Russians...

It was "American" to oppose godless communism. It was easy for the right to demonize the left as unpatriotic, out-of-touch and not fluent in the deified "free market."

The reclusive billionaire hedge fund manager Robert Mercer has been known to fund right wing groups in this country (Steve Bannon) and overseas (Nigel Farage). Like many of the self-made billionaires he's likely a fan of Ayn Rand and her apotheosis of selfishness in "Fountainhead" and "Atlas Shrugged," lauded by Congressman Ron Paul, Senator Rand Paul, Speaker Paul Ryan and President Ronald Reagan. It's funny how an avowed enemy of religion as a sickness can be so praised by those who put the Ten Commandments, godly masculinity and "family values" on high pedestals.

During the 1960's, COINTELPRO was concerned that foreign powers were infiltrating us and destabilizing our republic in the various Civil Rights organizations. They, along with the John Birch Society, were decidedly anti-communist, such that the Republican Party made this stance a litmus test for two generations. At that time, foreign Russian interference would have been called the KGB (Komitet gosudarstvennoy bezopasnosti, or the Committee for State Security). If they were infiltrating Civil Rights organizations, it was a time and an environment ripe for manipulation.

Fast-forward 40 years: 1968 - 2008. Forty years after the assassinations of Martin Luther King and Robert F. Kennedy, the country has gone through a massive experiment in forced busing that would eventually be objected to and eliminated. Cities would through economic opportunities and structured stratification re-segregate more so than 1968. The former Soviet Union would fall in that window in 1989. Then President George Bush (41) and Prime Minister Margaret Thatcher would opine on the "Peace Dividend." The previous Russian Politburo was their 1%. As I recall from Air Force ROTC class in college, they were the ones with the actual money while their populations starved. They had access to things like fashion, food, sex all the while pretending that the Politburo was "temporary" and eventually there would be pure Communism with no hierarchy, no stratification: no "income inequality" as we now call it. It never came. An attempt at reformation from the previous authoritarian communist regime - Democratization - would be attempted and fail. Some would say it was a weakness of Russian civil society, as in democratization usually entails a beneficial tug-of-war from above and below. If citizens aren't putting pressure on their leadership, that leadership will eventually go back to what they know well: ironclad, authoritarian control.

2008 saw the election of the country's first African American president, Barack Hussein Obama, for the first time in 232 years of the republic during a financial free fall compared quite literally to the Great Depression, a concern that furrowed his brow and eventually grayed his mane. A graduate of two elite schools, a Constitutional Scholar and community organizer, he "dotted every 'i' and crossed every 't'." His crowds were compared to rock concerts. We quickly spat out the bubblegum philosophy of a "post-racial" society. We had "grown up" Dr. Maya Angelou commented; poems were composed, t-shirts were made, tearful hymns were sung: we had finally "overcome."

President Obama's name was a source of angst to his legitimacy. Then the Tea Party arose, AstroTurf-fed by dark money - Koch, Mercer et al - as a faux grass movement, their bigotry was hidden - at least initially from their Tea Party selves - behind clever slogans and jingoism: "I want my country back!" The demographics was decidedly, predominately the only original creation of the American continent: "whiteness," and a few people of color comfortable in tokenism and able to maneuver within a religion of white supremacy, that itself masquerades as a faux evangelical Christianity.

The KGB became the FSB (Federalnaya Sluzhba Bezopasnosti, or Federal Security Service). Some rumors that they would weaponize misinformation on a scale heretofore unseen. As the former KGB observed an opening in the Civil Rights unrest, the FSB noticed Birtherism, the bigotry, the calling out "YOU LIE" during a president's State of the Union; the praying Psalms 109:8 and callously calling themselves "Christians." They saw faux voter integrity ID laws designed to act as a 21st Century poll tax; they saw the slaughter of Trayvon Martin, Jordan Davis, Renisha McBride, Eric Garner, Tamir Rice, John Crawford III, and countless others. Add to it the lack of any jurisprudence/convictions of their slayers (the noted exceptions in Davis and McBride): note also the rush to call them "thugs" and disappointed Kentucky fans "students." The clever bigotry giving way to blatant racism, our national pathology laid naked to any intelligence officers to manipulate. From the ascendancy of a rock star African American president, the situation demanded his precise antithesis as counterbalance.

It was simply a change in strategy: if COINTELPRO was correct (though biased), the infiltration was through some Civil Rights organizations. If our current intelligence is correct, the infiltration was through our obvious bigotry: it was designed to shatter our institutional norms, and internationally like democratic republics from within.

With fake news by bots and hackers, servers between Moscow and New York; backroom deals that may have been caught with (possible) FISA-warranted incidental communications monitoring, the Russians merely enacted in real-time cyber attacks the poignant observation President Lyndon Baines Johnson made on a trip to the south with journalist Bill Moyers:

"If you can convince the lowest white man he's better than the best colored man, he won't notice you're picking his pocket. Hell, give him somebody to look down on, and he'll empty his pockets for you."

With Brexit proceeding in the UK, spurred broadly by bigotry, their next targets to destabilize western democracy are France and Germany, with the ultimate goals of dismantling NATO and the European Union. There would be in essence a "New World Order" - not of the conspiratorial kind - but under the same conditions when "IRA" stood for Irish Republican Army (not Individual Retirement Account): there were a lot of bombings, death and instability. Before the EU, European countries often warred among themselves. That can't be good for tourism, ...or world peace.

We have "given them the store" of white supremacist bigotry, and our republic. I'm concerned apathy, racism, stupidity and tribalism may well not allow us... to get it back.

Lies and Automation...

Image Source: Mining.com link below

Topics: Alternative Energy, Economics, Jobs, Robotics

The times I've talked about automation: here, here, here, here, here, here, here, here, here and finally here. So it's not a new subject broached, hardly.

However the signature of repealing climate change rules merely to roll back your predecessor's executive order will benefit no one except the owners of the mines.

Robotics, not regulations is the reasons your mining jobs aren't coming back. A robot doesn't get sick, it doesn't have sick kids to stay home with; it doesn't require vacation/medical/dental/retirement benefits or get tired, however it will due to the 2nd Law of Thermodynamics (Entropy) wear down and eventually need repair. For that you need technicians, a specialty that can be awarded after two years study for an associates degree or military service in communications electronics or related military occupational specialty. So in this instance, a four year degree or higher is a bit of overcompensation and unnecessary from a cost-point concern, i.e. you could find yourself "overqualified" and not be hired due to the fact the potential employer is likely to think this is an interim assignment and you'll just find a better paying job when one opens.
We are ALL on a giant spaceship on an elliptical trajectory around the sun that takes approximately 365.25 days as we measure it, adjusted every fourth year with a "leap day" on which here in America we've parked our presidential election years. Due to the angle of incidence of ultraviolet light and our respective proximity on the globe, Melanin has rendered identifying pigmentation to different groups. We have no spare planets like it within the solar system or light years in human lifetimes. Learning to share within our respective sandbox is the only immediate surety for species survival in the near future.

Politicians on both sides of the aisle have been ambivalent and avoided discussing it to placate the electorate through another election cycle, our political thinking like our financial reduced to quarterly concerns, not existential ones. The best way to obfuscate is to punt about "clean coal" (an oxymoron), alternative energy (that will take considerable national will and government investment - e.g. the oil industry has literally been on government subsidies since the Bolshevik revolution), and of course demonize "the other" that doesn't look quite like your constituents in the first place (it tends to work "like a charm"; see ultraviolet and Melanin above).
That would take considerable synaptic activity, some long-range planning and a little less solipsism.

Graphic Novel Cover

The Flying Bullet: Graphic Novel/Film---A Sci-Fi; Story going from the Cotton Field to Outer Space

Heroes Like Me Entertainment will release a graphic novel and film called THE FLYING BULLET. It is the tale of Tuskegee Airman, Lt. Curt Masters, who is kidnapped by aliens and has to fight for an Earth that doesn't fight for him. This project has been six years in the making.

Lt. Curt Masters, a Tuskegee Airman, is flying a combat mission over the skies of Nazi Germany in 1945. He encounters an alien craft. He engages the craft unsuccessfully. Soon, he is aboard the UFO and is charged with Obstruction of Galactic Operations. He and the people of earth are on trial for their survival. Can Curt Masters free himself from over a billion miles away? Will he ever return home? Or will he die at the hands of The Warlord. In this new universe, he meets Aliena-a Galactic Police officer, Sutter-a mysterious friend or foe and ARC, who is an android without a will of his own. Curt will learn that once you Look Forward you can Never Go Back. Written by Chris Love, this graphic novel offers new worlds and possibilities. A companion feature film has been adapted from this graphic novel.

This is not a Hollywood blockbuster, but a film by one person, Christopher Love. This film is an independent film made by a fan of sci-fi for fans of sci-fi. The characters in the film will be of african-american, asian and hispanic descent.

"During World War II, Black and White Lives, including First Lady, Eleanor Roosevelt; petioned the government to allow Black Americans to fight and defend their country by training them to fly. All they asked in return was the opportunity to enjoy in the blessings of our great nation. This story is about one person who had to fight and defend the whole planet," says Chris Love.

This graphic novel/film is in the direct response to the lack of diversity in Science Fiction and Fantasy.

"We've waited for Hollywood to present stories of the future that has more than Caucasian characters in it. The Future is for everyone, but on the big screen I do not always see someone like me or my kids in that future. I'm doing this for them and other kids of color and diversity who deserves to see themselves on the big screen, tablet or phone to enjoy. Everyone deserves heroes that look like them," says Chris Love.

This is Mr. Love's first graphic novel and film. He has been writing for over 20 years. He is the Chief Creative Officer of Heroes Like Me Entertainment.

Mr. Love concludes by saying, "If you want something you never had, you must do something you never did."

Failure...

Credit: Getty Images
Topics: Education, Science, STEM, Research

I've failed quite often.

I've received D's on Quantum Mechanics homework from an admired professor with the admonition "SEE THE ANSWER" in all caps as if shouting from the paper. I remember crying, largely out of frustration and out of the fact I truly had deep respect for the professor, who had talked me into majoring in physics in the first place (I was initially a math major). I also remember looking at the solutions in the Mezzanine of the library. I saw where my mistakes were. My next homework grade was a B- and my test score was an A. I passed Quantum with a high B overall.

Failure is a large part of the scientific enterprise. A story I heard years ago from a Thomas Edison experiment with a lab assistant (there had been an explosion):

Assistant: "When are you going to give up this crazy idea? This is the 9,999th time you've tried to invent this light bulb!"

Edison: "Yes. This is the 9,999th time we tried to invent the light bulb. But there's an explosive application that could prove useful later."

"Do not worry too much about your difficulties in mathematics, I can assure you that mine are still greater," Albert Einstein. I think he was referring to learning Tensor Calculus to describe the General Theory of Relativity.

Somehow we miss the fact that when Einstein was working at a patent office in Germany, he probably saw himself as a failure. He took a job because he'd made his then girlfriend pregnant. Being responsible, he took a job to support his new family. His "Miracle Year" was 1905 when he published four papers: The Photoelectric Effect, Brownian Motion, Special Relativity and Mass-Energy Equivalence (E=mc2).

The competitive nature of western civilization doesn't allow or celebrate failure. Reality television, sporting contests, millennials awarded medals for "just showing up" at t-ball doesn't account for the many stutter steps if not downright stumbles a team makes to a championship. We celebrate the aftermath; the end result looking effortless and inevitable, the great discoveries often preceded by a lot of hard work and...failure.

Some of that failure is by design: peer review I've often stated can be brutal and demeaning. It can discourage anyone in the sciences to rethink if this is "what you really wanted to do with your life." A whole comic series was started by Jorge Cham (who has a PhD in Mechanical Engineering) quite literally on this angst.

There are sleepless nights, long experiments that take you through weekends (that everyone else outside seems to be enjoying). "Why am I doing it"? you may ask.

I tend to think of loud explosions and parents that didn't freak out (largely because I didn't die nor their house didn't burn down).

You throw yourself back into the lab, the chalkboard or the computer program...out of love.

People in the sciences are usually there because they love it: solving complex problems is almost meditative; spiritual in the satisfaction of not just solving problems, but birthing in many cases something that didn't previously exist. Someone in their past supported them despite their socioeconomic status, gender, sexual orientation and said four important words: "you can do it."

And to show our love of the area and the support from family and friends, many of us did.

**********

Four weeks into my first semester of college, my academic confidence was completely shredded. I had back-to-back tests in cell biology, chemistry, and calculus, and my time management skills weren’t quite there yet. I failed my calculus exam, and suddenly I wasn’t sure I had the intelligence or the ability to get a degree in science.

My story has a happy ending—at least to me. Through stress eating, meltdowns, and support from my professor and older students, I studied my way to an A-minus in that calculus class. But, even better: I learned how to fail, something I keep learning and relearning as I come to the end of my second semester in graduate school. It’s the fundamental underpinning of scientific resilience—failing repeatedly, and picking yourself up to try again.

It’s what I think is missing from many young Americans’ educational experiences, and, in part, why I think so many of us, as smart and creative and technically adept as we are, shy away from scientific research as our careers.

Learning resilience is fundamental to a successful career as a scientist. The experiments we try will fail many times before they work, whether as an undergraduate, a PhD student, or a postdoc gunning for a faculty position.

But actually overcoming failure is challenging. Many students who began science degrees with me switched to other majors the first time a project failed. One failure and they were gone.

This dropout situation has lasting implications for American science. The US has plenty of scientists, but fewer and fewer are being born in the US. These foreign-born scientists are welcome, as far as I’m concerned, but with all the recent changes in immigration and visa policy, it’s an uncertain future—large numbers of our scientists-in-training could be forced to leave after they finish graduate school or postdocs.

Without these scientists, American science will suffer.

Martian Tsunamis...

Topics: Mars, NASA, Planetary Science, Space Exploration, Spaceflight

Scientists have located an impact crater linked to powerful tsunamis that swept across part of ancient Mars.

The team believe an asteroid triggered 150m-high waves when it plunged into an ocean thought to have existed on northern Mars three billion years ago.

Lomonosov crater in the planet's northern plains fits the bill as the source of tsunami deposits identified on the surface.

Details were outlined at the 48th Lunar and Planetary Science Conference.

Although the idea has lost some of its currency in recent years, some scientists think an ocean might once have filled the vast lowland region that occupies the Red Planet's northerly latitudes.

Growing evidence that tsunami waves washed over the boundary between the southern highlands and northern lowlands help strengthen the hypothesis.

CAL...

NASA will use CAL to better try to understand a highly misunderstood type of matter in space. Image Credit: NASA

NASA has a goal of creating what they say will be the coldest place in the entire universe, as it will help them to understand a property of matter that isn't well-understood. The project has been in development for a number of years, but soon it will come to fruition.

In the near future, an ice chest-sized box that NASA is calling the Cold Atom Laboratory (CAL) will be shipped to the International Space Station aboard a supply rocket.

CAL will come equipped with the tools it needs to hyper-chill gas atoms to just a billionth of a degree above absolute zero, which citing NASA, is about 100 million times colder than even the depths of outer space itself. It's worth noting that at absolute zero, atom activity reportedly freezes. The tools that will make this possible include a vacuum chamber, special lasers, and what NASA calls an “electromagnetic knife.” These tools will essentially slow the gas molecules that get trapped inside to a near-motionless state.

Since there is so much misunderstanding about how these kinds of hyper-chilled properties impact physics, this is a huge opportunity to fill a gap in mankind's expanding knowledge. The gasses that get chilled to these kinds of low temperatures really aren’t even gasses anymore – their atoms become arranged into a state of matter dubbed Bose-Einstein Condensate. This is a unique type of matter that we don’t fully understand yet. Scientists describe it as a type of “super fluid” that lacks any friction.

A supermassive black hole heftier than 1 billion suns has been ejected from the core of its galaxy by gravitational waves, a new study suggests.

The monster black hole has already zoomed 35,000 light-years away from its galaxy's center, farther than Earth and its sun are from the core of our own Milky Way. And the behemoth is currently traveling outward at 4.7 million mph (7.6 million km/h) — fast enough for the black hole to escape its galaxy completely in 20 million years, researchers said.

“We estimate that it took the equivalent energy of 100 million supernovae exploding simultaneously to jettison the black hole,” study co-author Stefano Bianchi, from Roma Tre University in Italy, said in a statement.

Does the brain behave like a spin glass? (Courtesy: Shutterstock / Phonlamai Photo)

Topics: Biology, Biophysics, Neuroscience, Particle Physics

Spin-glass-like states that occur in models of neural networks can provide important insights into states of low and high brain activity that have been observed in mammals. That is the claim of a team of theoretical biophysicists in Spain who are the first to show that disordered states in neurological networks could have a functional role in living brains.

In familiar magnetic materials such as ferromagnets, the interaction between individual spin magnetic moments causes all of the spins to point in the same direction of magnetization. In spin-glass states, the interaction between spins does not allow individual spins to point in the same direction as their neighbours. This leads to "frustration", whereby no direction of magnetization exists and the spins point in random directions.

Brains are not magnetic systems and their working cells – neurons – do not resemble magnetic moments, but mathematically they behave in a similar manner. This is because neurons also have a binary variable – firing or not firing – which is similar to the up or down quantum states of spin. Neurons are also linked by synapses in a way that is similar to how magnetic spins interact with each other. As a result, a neural network in which all of the neurons are firing (or not firing) is similar to a magnetic material in which all of the spins are all pointing up (or down).

New NASA research reveals that the giant Martian shield volcano Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity. The last volcanic activity there ceased about 50 million years ago—around the time of Earth's Cretaceous-Paleogene extinction, when large numbers of our planet's plant and animal species (including dinosaurs) went extinct.

Located just south of Mars' equator, Arsia Mons is the southernmost member of a trio of broad, gently sloping shield volcanoes collectively known as Tharsis Montes. Arsia Mons was built up over billions of years, though the details of its lifecycle are still being worked out. The most recent volcanic activity is thought to have taken place in the caldera—the bowl-shaped depression at the top—where 29 volcanic vents have been identified. Until now, it's been difficult to make a precise estimate of when this volcanic field was active.

"We estimate that the peak activity for the volcanic field at the summit of Arsia Mons probably occurred approximately 150 million years ago—the late Jurassic period on Earth—and then died out around the same time as Earth's dinosaurs," said Jacob Richardson, a postdoctoral researcher at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "It's possible, though, that the last volcanic vent or two might have been active in the past 50 million years, which is very recent in geological terms."

Richardson is presenting the findings on March 20, 2017, at the Lunar and Planetary Science Conference in The Woodlands, Texas. The study also is published in Earth and Planetary Science Letters.

Deciphering Auroras...

Topics: Electromagnetism, High Energy Physics, Plasma Physics

Auroras have long dazzled sky watchers but befuddled physicists. Via a mechanism that remains unclear, electrons get yanked away from the magnetosphere and slammed into the ionosphere, where their collisions with atoms and molecules engender green, red, and blue light. (See the Quick Study by Bob Strangeway, Physics Today, July 2008, page 68.) The leading culprits for scooping up and accelerating auroral electrons are Alfvén waves, oscillations of the ions in a plasma that propagate along magnetic field lines. The oscillations can be triggered by magnetic storms, which often portend auroral displays. And at least in theory, the waves should be able to propel electrons in their path.

Auroras: The sun sends us more than heat and light; it sends lots of other energy and small particles our way. The protective magnetic field around Earth shields us from most of the energy and particles, and we don’t even notice them.

But the sun doesn’t send the same amount of energy all the time. There is a constant streaming solar wind and there are also solar storms. During one kind of solar storm called a coronal mass ejection, the sun burps out a huge bubble of electrified gas that can travel through space at high speeds. Source: NASA

Alfvén waves: In plasma physics, an Alfvén wave, named after Hannes Alfvén, is a type of magnetohydrodynamic wave in which ions oscillate in response to a restoring force provided by an effective tension on the magnetic field lines. Wikipedia

Although the invisible substance known as dark matter dominates galaxies nowadays, it was apparently only a minor ingredient of galaxies in the early universe, a new study finds.

This new finding sheds light on how galaxies and their mysterious "haloes" of dark matter have changed over time, researchers said.

Dark matter is thought to make up about 84 percent of the matter in the universe. Although dark matter is invisible, its presence can be inferred by its gravitational effects on visible matter. For instance, previous work discovered that the outer parts of galactic disks whirl faster than expected around the cores of those galaxies. These findings make sense if one assumes that "haloes" of dark matter envelop those galaxies and gravitationally pull at their outer regions. [The Search for Dark Matter in Pictures]

Now, the researchers unexpectedly find that in the early universe, dark matter played a much smaller role in galaxies than previously thought. The scientists detailed their findings in the March 16 issue of the journal Nature.

Using the European Southern Observatory's Very Large Telescope in Chile, the researchers examined six massive, star-forming galaxies from the early universe during the peak of galaxy formation 10 billion years ago. They analyzed the rotation of these galaxies to calculate how much dark matter they possessed.

History matters. It is "2 a: a chronological record of significant events (as affecting a nation or institution) often including an explanation of their causes, a history of Japan; 3: a branch of knowledge that records and explains past events, medieval history." Merriam-Webster

The more dependent we are on technology, the more we are flippant on history and expertise. Reading (sadly, on the decline) for example, is an interrogation of history, whether fiction or nonfiction, as some basis of an understanding of past events has to go into the crafting of even fanciful tales. Backgrounds are structured such that the verisimilitude seems plausible; if the author has done their work, the realistic realm pulls you to the last page of the book, whether papyrus, I-Pad, Kindle or Nook. If it's a good read, you feel accomplished, better for the effort and time spent away from passive, frequently banal entertainment media. Above all, one feels a sense of empowerment.

Our knowledge of civics has been reduced educationally to multiple testing choices a, b, c, d and e (the last usually, all of the above) and in practice "us versus them"; we won, you lost. The Common Good is virtually unknown as it has no reality show or equivalent entertainment platform. MSNBC seems recently captivated with sports metaphors: Chuck Todd with basketball and Chris Matthews with boxing.

Over the decades I've been voting since 1980, that attitude has solidified. "We The People" have been grouped by tribal affiliations, we vote for "who we like," the current anointed-by-God politician we tweet, and will likely never meet. Consensus, compromise and reconciliation is to be avoided; conciliation is betrayal. Our self-governance is now so toxic, old and vile prejudices open us up to manipulation; our pride allows us to self-delude and mask from the con that we have been duped by extra-national, nefarious agents and complicit wolves within.

I've mentioned my excellent high school Social Studies/Civics teacher Van Bullock. The other instructors I received civics lessons from were my high school JROTC and college AFROTC instructors. Senior Master Sergeant Wilkins at North Forsyth High School used to emphasize that democratic republics can only exist in educated populations. In insular environments such as these, one can assume your classmates are getting some version of the same teaching. I now have my doubts.

Timothy Snyder, author of On Tyranny warns that republics are not "automatic" nor are they inevitable. It requires a buy-in from the governed, a fundamental knowledge of the mechanism of republics and the citizen's responsibilities in keeping them going. One simple aspect is voting; the other is holding our elected officials accountable for their actions towards their constituency, not their donors or the donor class. That alludes to other forms of government that have the labels: autocracy, authoritarianism, corporatism, kleptocracy, oligarchy, totalitarianism that are the basis of very haunting dystopian novels of hopeless futures, Orwell's "boot stamping on a human face forever." Our lethargy in this country and overseas is due to the near instantaneous access to information, resulting in a citizenry in western nations that would "rather not think about it," or in the spirit of Sinclair Lewis, "It Can't Happen Here." In his prescient essay in 2004, Chris Hedges begs to differ *:

* The movement seeks the imprint of law and science. It must discredit the rational disciplines that are the pillars of the Enlightenment to abolish the liberal polity of the Enlightenment. This corruption of science and law is vital in promoting the doctrine. Creationism, or “intelligent design,” like Eugenics for the Nazis, must be introduced into the mainstream as a valid scientific discipline to destroy the discipline of science itself. This is why the Christian Right is working to bring test cases to ensure that school textbooks include “intelligent design” and condemn gay marriage.

The drive by the Christian Right to include crackpot theories in scientific or legal debate is part of the campaign to destroy dispassionate and honest intellectual inquiry. Facts become interchangeable with opinions. An understanding of reality is not to be based on the elaborate gathering of facts and evidence. The ideology alone is true. Facts that get in the way of the ideology can be altered. Lies, in this worldview, become true. Hannah Arendt called this effort “nihilistic relativism” although a better phrase might be collective insanity.

Failure to question alternative facts (lies) or stretched truths, or play by any fairness or rules, the lazy put their cares in the hands of one strong man or woman: as long as "their team" wins.

When sports loyalties becomes the foundation for the administration of a republic, it becomes a zero-sum game. Whatever you need to do to WIN is then justifiable, from secret, ultimately disastrous raids decided flippantly over dinner; deflated footballs to collusion with governments that are not looking at one party or another anymore than Al Qaeda or ISIL/ISIS has a preference of one western nation over another, or the particular Melanin hue of their respective babies.

In each case, they call themselves "us" and we, E Pluribus Unum... are  "them."

Even though this speculation sounds exciting, it makes us wonder if/how/when the lawsuit from Sophia Stewart was ever settled in such a way to spearhead this new chapter. Plus, it makes others ponder if this is a redemption publicity stunt to counter-spin the discrimination lawsuit that African-American employees have against Turner Time Warner right now.

BEAM...

The Bigelow Expandable Activity Module (BEAM) is an expandable habitat technology demonstration for the International Space Station. Expandable habitats greatly decrease the amount of transport volume for future space missions. These “expandables” require minimal payload volume on a rocket, but expand after being deployed in space to potentially provide a comfortable area for astronauts to live and work. They also provide a varying degree of protection from solar and cosmic radiation, space debris, atomic oxygen, ultraviolet radiation and other elements of the space environment.

The journey to Mars is complex and filled with challenges that NASA and its partners are continuously working to solve. Before sending the first astronauts to the Red Planet, several rockets filled with cargo and supplies will be deployed to await the crews’ arrival. Expandable modules, which are lower-mass and lower-volume systems than metal habitats, can increase the efficiency of cargo shipments, possibly reducing the number of launches needed and overall mission costs.

Bigelow Aerospace founder Robert Bigelow‘s company makes in-space habitats. One (the BEAM adds 16 cubic meters of living area to the ISS) is now attached to the International Space Station and he and his company are developing permanent, stand-alone habitats to serve as private space stations in orbit around the Earth, ready to house private astronauts.

Bigelow has talked with United Launch Alliance Chief Executive Tory Bruno about using the company's Atlas V 552 rocket, which has an extra-wide payload fairing, to deliver the B330 into orbit.

United Launch Alliance is developing an advanced upper-stage vehicle, ACES, to provide in-space propulsion.

Two ACES in tandem could be used to move the B330 into a low lunar orbit. They orbit within 75 kilometers of the lunar surface.

Bigelow has spoken SpaceX President Gwynne Shotwell about using the company's Dragon 2 spacecraft to transport astronauts to the B330 in deep space.

By 2020, NASA and commercial astronauts could be living and working in lunar orbit inside a functional space station. [2]

ProtoDUNE...

This 11 m-high structure with thick steel walls will soon contain a prototype detector for the Deep Underground Neutrino Experiment (DUNE), a major international project based in the US for studying neutrinos and proton decay. It is being assembled in conjunction with CERN’s Neutrino Platform, which was established in 2014 to support neutrino experiments hosted in Japan and the US (CERN Courier July/August 2016 p21), and is pictured here in December as the roof of the structure was lowered into place. Another almost identical structure is under construction nearby and will house a second prototype detector for DUNE. Both are being built at CERN’s new “EHN1” test facility, which was completed last year at the north area of the laboratory’s Prévessin site.

DUNE, which is due to start operations in the next decade, will address key outstanding questions about neutrinos. In addition to determining the ordering of the neutrino masses, it will search for leptonic CP violation by precisely measuring differences between the oscillations of muon-type neutrinos and antineutrinos into electron-type neutrinos and antineutrinos, respectively (CERN Courier December 2015 p19). To do so, DUNE will consist of two advanced detectors placed in an intense neutrino beam produced at Fermilab’s Long-Baseline Neutrino Facility (LBNF). One will record particle interactions near the source of the beam before the neutrinos have had time to oscillate, while a second, much larger detector will be installed deep underground at the Sanford Underground Research Laboratory in Lead, South Dakota, 1300 km away.

YAY TEAM!

The engineer's cheer (supposedly from MIT). Lowercase "e" is the natural logarithm (also an irrational number), "dx" in Calculus defines small, infinitesimal change in the variable x; four Trigonometric terms and Pi (symbol: π) you know.

Once you see it, you can't UN-SEE it. I have officially corrupted you.

Also to note: Albert Einstein's birthday happens to be today. In 2015, National Pi Day had some significance as it was his birthday and the year General Relativity was confirmed observing the phenomena we now know as Gravitational Lensing 100 years prior, giving rise to studying a now popular enigma of the universe: Black Holes.

NASA is giving space fans a reason to celebrate Pi Day, the March 14 holiday created in honor of the mathematical constant pi. For the fourth year in a row, the agency’s Jet Propulsion Laboratory has created an illustrated Pi Day Challenge featuring four math problems NASA scientists and engineers must solve to explore space. The challenge is designed to get students excited about pi and its applications beyond the classroom. This year’s problem set, designed for students in grade six through high school – but fun for all – features Mars craters, a total solar eclipse, a close encounter with Saturn, and the search for habitable worlds.

Educators, get the standards-aligned Pi Day Challenge lesson and download the free poster and handouts. The answers to all four problems will be released in a companion infographic on March 16.

Why March 14?

Pi is what’s known as an irrational number, meaning its decimal representation never ends and it never repeats. It has been calculated to more than one trillion digits, but NASA scientists and engineers actually use far fewer digits in their calculations (see “How Many Decimals of Pi Do We Really Need?”). The approximation 3.14 is often precise enough, hence the celebration occurring on March 14, or 3/14 (when written in US month/day format). The first known celebration occurred in 1988, and in 2009, the US House of Representatives passed a resolution designating March 14 as Pi Day and encouraging teachers and students to celebrate the day with activities that teach students about pi.
