In their order of appearance:

Project #21, Burglar alarm (3D snap kit)

Project #11, Flying Saucer

Project #53, Flashing Laser Light with Sound

Project #548, Rechargeable Battery (solar panel)

The Joint School of Nanoscience and Nanoengineering will participate in the USA Science and Engineering Festival as part of the North Carolina Science Festival. Our portion is called "Gateway to Science." I am a humble one of many great exhibits. I'll start 9:00 am at the Nano Energy table (my group), then take the evening shift from 1:00 - 5:00 pm at the electronic snap kits table I spent until 9:30 last night setting up, as well as I saw many other fellow students setting up their displays in the wee hours. Like anything, it's something you're at first "voluntold" to do, but take pride in your particular part coming off without a hitch. It's going to be a long, eventful day. I'll try to get some other photos posted when I get a break.

Cephalopod IR...

A simple device with tuneable infrared reflectivity has been made by mimicking the adaptive properties of the skin of octopuses and related animals. Chengyi Xuat, Alon Gorodetsky and George Stiubianu of the University of California, Irvine created the device using a dielectric elastomer and say that it overcomes many of the limitations of previous adaptive infrared-reflecting systems.

Reflecting infrared radiation is important for many technologies, ranging from building insulation to spacecraft components. But most of the materials used to reflect radiation in the infrared region are static: they are unable to respond and adapt to changes in the environment. Some adaptable infrared-reflecting systems have been developed, but they tend to be complex and difficult to control, while also lacking spectral tunability and requiring high operating temperatures.

Inspired by the skin of cephalopods – squid, octopuses, and cuttlefish – Gorodetsky and colleagues have now developed an adaptable infrared-reflecting system that they say is easy to control, can respond rapidly and be used repeatedly. The system also has a tuneable spectral range and works at low temperatures.

Many cephalopods can rapidly change the colour and patterning of their skin. This is done for both camouflage and signalling, and is enabled by pigment cells with adjustable spectral properties that can response within hundreds of milliseconds. These yellow, red, and brown cells, known as adaptive chromatophores, are packed with pigment granules and can be expanded and contracted by radial muscles. As their size and shape changes so do the wavelengths of light that they absorb and reflect.

Well-heeled space tourists will have a new orbital destination four years from now, if one company's plans come to fruition.

That startup, called Orion Span, aims to loft its "Aurora Station" in late 2021 and begin accommodating guests in 2022.

"Affordable" is a relative term: A 12-day stay aboard Aurora Station will start at $9.5 million. Still, that's quite a bit less than orbital tourists have paid in the past. From 2001 through 2009, seven private citizens took a total of eight trips to the International Space Station (ISS), paying an estimated $20 million to $40 million each time. (These private missions were brokered by the Virginia-based company Space Adventures and employed Russian Soyuz spacecraft and rockets.)

"There's been innovation around the architecture to make it more modular and more simple to use and have more automation, so we don't have to have EVAs [extravehicular activities] or spacewalks," Bunger said of Aurora Station.

Elysium or the Elysian Fields (Ancient Greek: Ἠλύσιον πεδίον, Ēlýsion pedíon) is a conception of the afterlife that developed over time and was maintained by some Greek religious and philosophical sects and cults. Initially separate from the realm of Hades, admission was reserved for mortals related to the gods and other heroes. Later, it expanded to include those chosen by the gods, the righteous, and the heroic, where they would remain after death, to live a blessed and happy life, and indulging in whatever employment they had enjoyed in life.

for sometime now I’ve wanted to complete this Black and white in color.

steven just began the color works. It was submitted as part of an Blackage Anthology Book

that fell through yeatrs ago. It now posted as an extra on line story on Stranger web page

at Ghettostone Publications site. Recently I have attempted to contact director and movie creator Mr. Fuqua

of Training Day fame to ask if they would please take a look. Stranger storyline has been featured in an independence film years ago, but I think the film success of Black Panther has inspired movie goers so why not try again.

Stranger is ageless and bright to America in the hula of a slave ship ( check Universe book O) from ghettostone, but

he is our Universes ultimate evil doer. Always hidden in the shadows The Stranger would be the last thing you see before your demise.

I enjoy writing for villians they are much easier to write that heroes because most people dont

beliveve in heroes any more and ask why would a super powered hero help anyone as opposed to

gettin paid or becoming famous. Villians from a Black perspective I thing should reflect history

and power so The Stranger brought to America in a slaveship morphs into a Werewolf and manipulates

youth into his evil service. He appears in all my stories so far except for RAMZEES.

Here a page from a quick down and dirty Blackage Anthology Book that never was, enjoy

Nanowire Fusion...

Smaller, cheaper neutron sources and new opportunities for simulating the extreme conditions at the center of stars are among the possible benefits of new research carried out by physicists in the US and Germany. The group directed rapid-fire pulses of intense blue light from a compact laser at arrays of nanostructures to generate a dense plasma yielding large numbers of neutrons created by nuclear fusion.

Scientists have built ever more energetic lasers in the quest to demonstrate nuclear fusion’s feasibility as an energy source. The National Ignition Facility (NIF) in California, for example, generates pulses with a whopping 1.8 MJ of energy, in order to compress tiny pellets of deuterium and tritium to the point where the nuclei fuse and emit copious numbers of neutrons. The aim is to achieve ignition, when the alpha particle released by the fusing nuclei provides the heat for a self-sustaining reaction – with the energy of the emitted neutrons ultimately being tapped to produce electricity. However, NIF is enormous – occupying the area of three football pitches – and, like other high-energy lasers, can only fire a handful of times a day.

Some researchers are instead working on less energetic but more rapid-fire lasers. These will never get anywhere close to ignition, but can still achieve exceptionally high intensities – thanks to the extreme brevity and hence power of their pulses. Such lasers can create plasmas with very high energy densities ideal for studying extreme astrophysical environments, for example. These devices could also potentially be used as compact sources of neutrons, which probe atomic structure in ways not possible with X-rays. Neutrons are usually produced at large accelerators or reactors and a compact source would be welcomed by scientists.

Ye Shall Know the Truth...

Posted by Reginald L. Goodwin on April 6, 2018 at 5:23am

Allen Dulles, the fifth and longest-serving Director of Central Intelligence, took a personal interest in the construction of the Original Headquarters Building (OHB). He was the son of a Presbyterian minister and insisted that a Biblical quotation be fixed in stone in the OHB Lobby. The verse – "And Ye Shall Know the Truth and the Truth Shall Make You Free" – John 8:32 – now stands as the Agency motto. At the dedication ceremony for OHB, Dulles included this quotation in his speech. Source: CIA.gov

Whatever your opinions of them, that is the motto of our preeminent spy agency, one of the 17 intelligence agencies along with what's left of our allies that has confirmed Russia interfered in the 2016 elections that our current president* exhaustively and nauseatingly labeled "fake news."

On August 19, 2016, I wrote a blog post titled: "These Truths..." It talked about self-evident, rational truths, such as evolution, the age of the universe; governance. Those were halcyon days, when we had a president and not a president*/embarrassment. When we (at least, as member of the non-bigoted, saner part of the electorate), were convinced our president had fidelity to his marriage, his country and its Constitution.

Excerpt from "These Truths":

This year's election is unique as one political party has nominated such a flimflam artist as its candidate, that has made no bones about his hostility to science: "climate change is a plot by the Chinese against American manufacturing." As the New York Daily News opined on his loose 2nd amendment comments: "this isn't funny anymore."

This is an assault on fact versus fantasy, science versus psychobabble; sanity versus insanity. Flimflam's persona non grata interviewed on Alex Jones - the KING of conspiracy provocateurs - as a casual search of YouTube on his rant compilations attests, many right wing pundits have, as he's complained - mainstreamed his views in the public sphere without crediting him, only nourishing a faux ecosystem around Mr. Flimflam. FF sometimes quotes him verbatim, which Jones says admirably is "surreal."

This president*/flimflam artist denies knowing of $130,000 payment to Stormy Daniels. Unlikely. His lawyer apparently gives it from his own home equity, supposedly not expecting to get repaid. The problem is, if the president* had paid him back, it wouldn't be an in-kind donation during an election, an FEC violation. And why ISN'T a "billionaire" writing a check for his own hush money payments? There is likely a prenuptial agreement he'd be in violation of if this proves out true, and that will cost flimflam what little money Putin lets him dip his toes in.

What it does mean: 1. A lawyer MUST inform his client of any contractual agreement s/he enters into on behalf of her/him. 2. By denying the NDA (non-disclosure agreement) with an adult film star, he may have essentially nullified it. He also has one with a Playboy centerfold with which he supposedly had a long-term affair. Stormy's lawyer salivates at the prospect of questioning the president* and his lawyer under deposition. I relish when, as he did from his first spouse where he invoked his Fifth Amendment right to not self-incriminate ninety-seven times, he does so again - hilariously and maddeningly under oath.

What exactly is "truth" in this president*'s era? He has the all-time Olympic record for fabrications, fibbing; lying and obfuscations. His evangelical base seems unmoved by his past, his present dissembling and twitter ranting. They had conniption fits when President Clinton had a consensual relationship with an ADULT (albeit young) White House intern. A blue dress with spermatozoa was salacious; "grab 'em by the p----" on Access Hollywood deserving of a Mulligan. The rank hypocrisy of what amounts to an authoritarian political movement masking itself as a religious order self-imposed to tell everyone ELSE how to live is breathtaking. The word "EVILGELICALS" should become a thing in our modern lexicon; they should not recover, and the congregations in their immediate futures should be comprised of crickets.

If indeed, "the truth shall make you free"...an avalanche of lies from a president* backed by a faux religious order - evilgelicals - is a prelude to slavery.

Superconducting Nanotech...

Posted by Reginald L. Goodwin on April 5, 2018 at 8:10pm

Almost a century after Heike Kamerlingh Onnes first discovered superconductivity, the factors that determine whether a system will be superconducting and at what temperature remain hard to pin down. However, advances in nanotechnology have given some good pointers where to look, as well as providing promising systems for exploiting superconductivity in real-world applications.

The fundamental requirement for superconductivity is the coupling of fermionic electrons into Cooper pairs. Theory paints a neat picture of how the resulting bosonic behaviour allows occupation of the same energy levels and leads to a host of exotic behaviour - zero electrical resistance and the expulsion of magnetic flux lines so that superconducting objects levitate on magnets, to name a few. Where the picture grows fuzzy is extrapolating from there what specific aspects a material system needs to become superconducting at a given temperature. While design principles to fabricate a room-temperature superconductor remain elusive, a lot has been learnt in the chase, bringing applications of superconductors in a range of sectors from imaging, testing and quantum cryptography ever closer.

2D materials

Among the material systems where unusual electronic behaviour akin to Cooper pairing might be likely is the interface between perovskite oxides – in particular, LaAlO3 and SrTiO3 – where there is a discontinuity in the polarity of the crystalline lattice. Following the initial discovery of a highly mobile “2D electron gas” at the interface in 2004, Jochen Mannhart and colleagues then identified superconducting properties at the interface in a layer limited to just 20 nm in 2007. The transition temperature was a chilly 200 millikelvin, and the exact origins of the effect were unclear, but oxide interfaces remain a hotbed for exploring electronic and spintronic behaviour.

Since then several 2D structures have revealed superconducting behaviour where it does not exist in the bulk, an example being “grey” tin. The form of tin usually considered most useful is “white” tin, which has a conventional metal crystallographic structure, and was among the first superconducting materials to attract study. However, at low temperatures white tin will gradually transform into grey tin, which has a diamond cubic structure and is sometimes described as “tin pest”. To their surprise, Qi-Kun Xue, Ding Zhang and colleagues at Tsinghua University in China found that when they reduced the dimensions of tin to 2D stanene of just 2-20 layers, they could observe superconducting properties in grey tin too. Going even thinner to monolayers resulted in insulating properties.

"What we found is that the grey tin can be scientifically quite interesting," Zhang told nanotechweb.org. As well as the fundamental science the discovery opens up, it also poses the opportunity to produce circuits from all one material, with superconducting wires of few layer stanene separated by insulating monolayers.

Designs Mag - Dr. Martin Luther king Jr. Timeline 2015

Topics: African Americans, Civil Rights, History, Human Rights, Martin Luther King

I believe the little girl with Dr. Martin Luther and Coretta Scott King is Yolanda. She is deceased now along with her parents, but her niece namesake just spoke at the March For Our Lives, looking remarkably like her iconic grandfather. Despite all the reveals of Dr. King as a flawed philanderer as investigative journalists are apt to do, he was at the end of the day a husband, a man and a father. As he said on the previous day, "longevity has its place." His death came year-to-date of his denouncement of his nation's involvement in Vietnam, that would eventually claim the lives of almost 60,000 soldiers, sailors and airmen, affecting survivors with post traumatic stress disorder; drug abuse, alcoholism and suicide. Total deaths numbered in the millions. Had he lived, I'm sure he would have addressed these concerns as part of his vision of "The Beloved Community," which ostensibly included all of humanity.

I would hear my parents cry.

They would still be crying as they tried to get through their daily routine. Getting me ready for kindergarten at Bethlehem Community Center. I had seen my mother cry on occasion - church, funerals - my father's eyes were red and his hands trembled as we drove from our home to school. They were both worried about my older sister - a youth active in the Civil Rights movement. They briefly didn't know here whereabouts. The worry hung over the home like a dark veil. I was too: like every march, every demonstration where it wasn't guaranteed she'd get out of it alive. It was a lot for someone new to the planet sometimes. She turned up, heartbroken. She and my mother hugged each other and cried, inconsolably.

This was a time of emotions - rough, raw and gut-wrenching. I was five years old. I didn't know what to feel until I arrived at Bethlehem.

I remember seeing this the night before from my father's lap:

But I'm not concerned about that now. I just want to do God's will. And He's allowed me to go up to the mountain. And I've looked over. And I've seen the promised land. I may not get there with you. But I want you to know tonight, that we, as a people, will get to the promised land. And I'm happy, tonight. I'm not worried about anything. I'm not fearing any man. Mine eyes have seen the glory of the coming of the Lord.

I didn't quite understand his eloquence. I asked my father. It was April 3, 1968. He honestly didn't know.

These broadcasts were probably what caused the walls of hope to come crashing around my family:

The preschool and kindergarten teachers at Bethlehem decided to explain our loss to us the next day, partly to process what had just happened themselves. We did all cry, finally - as if we had just lost a favorite uncle or grandfather. Barely on the planet, we were suddenly having to contemplate a loss as tears fell like rainwater in a storm. Dr. King would come on the black radio station WAAA in Winston-Salem, NC as they broadcast a program from the Southern Christian Leadership Conference "Martin Luther King Speaks." I remember hearing his distinguished voice; the pitch and pentameter of a preacher well-rehearsed and natural to him. I remember when it wasn't a recording of a deceased ancestor.

We went to nap early. It was all the energy has to do. We awoke to the blaring sounds of horns, the sight of confederate flags flown from pickup trucks and shotguns, celebratory of his death; the shouts of dark triumph from a sick cadre. That day, we played inside.

Dr. King was the victim of gun violence by a confirmed racist. Despite any theories about who actually performed the deed, what the motivations were, whether or not the government was involved: he was a victim of gun violence, a long line in this country, before breathless pronunciations of ArmaLite 15 rifles. As was Malcolm X. As was Medgar Evers. As were members of the Black Panther Party of self-defense. As would Robert Kennedy follow in the dark shadow of his brother, President John F. Kennedy. From Native American genocide, African kidnappings followed by: lynchings, castrations, body burning, burning crosses, voter intimidation, church bombings, the slaughter of innocents by the police or citizens empowered by fear and bigotry; the "othering" of an African American president by his pathologically lying grifter successor - the red stripes in the flag aren't just those of "Founding Fathers," and patriots (or, revamped psychopaths), but the blood of violence shed by this nation's victims. We were in "the promised land" for eight, short years! We were inexorably pushed by bigotry and birtherism to a nascent nostalgia for mythological white picket fences; economic isolationism, ethno-nationalism, social, sexual and cultural demarcations: "great again" for some, and not for "others." As a nation, we've been at war - externally with enemies and internally, with one another - more than we've ever been at, or encouraged peace.

After every shooting of innocents, we often in naval-gazing fashion say something to the effect of "we're BETTER than this!" In 50 years of violence I've witnessed since in wars, rumors of wars, gang violence, crack and meth addiction, the expansion of the wealth gap; an increase in productivity while wages remain stagnant at 1973 levels (Dr. King was in Memphis campaigning for wage increases for sanitation workers); healthcare debated as privilege or right and the current position we find ourselves in with a demagogue installed by an enemy state in possession of the nuclear codes, I'm not so sure we are any better than what's evidenced. Perhaps...not.

Physicists have identified a new state of matter whose structural order operates by rules more aligned with quantum mechanics than standard thermodynamic theory. In a classical material called artificial spin ice, which in certain phases appears disordered, the material is actually ordered, but in a "topological" form.

"Our research shows for the first time that classical systems such as artificial spin ice can be designed to demonstrate topological ordered phases, which previously have been found only in quantum conditions," said Los Alamos National Laboratory physicist Cristiano Nisoli, leader of the theoretical group that collaborated with an experimental group at the University of Illinois at Urbana-Champaign, led by Peter Schiffer (now at Yale University).

Physicists generally classify the phases of matter as ordered, such as crystal, and disordered, such as gases, and they do so on the basis of the symmetry of such order, Nisoli said.

"The demonstration that these topological effects can be designed into an artificial spin ice system opens the door to a wide range of possible new studies," Schiffer said.

Astronomy Queen...

Will I ever know the truth about the stars?

I’m too young to engage in theories about our Universe.

I just know that I want to understand more. I want to know all

I can. Why should it be forbidden?

This sentence, found on a votive jar dedicated to her grandmother, had been written by a young girl, a Korean princess of the Silla Dynasty, when she was 15 years old. Her name was Sonduk, but it is also written as Sondok or Seondeok, and she was very interested in astronomy in an era where no education was granted to women. Nevertheless, she became a queen and could pursue her astronomical passion, at least in a certain sense. But let’s go in order.

She was born in 610 CE, and later became the first female monarch of Korea, ruling her country for 14 years. Jinpyeong, her father, was the king of Silla, a kingdom that was born as a city-state in 57 BCE and grew into a kingdom in about 350 CE. The king had no male heirs, so the choice fell on his daughter Sonduk.

This young princess had a brilliant mind, evident from a very young age. At seven, for example, a box of peony seeds arrived at the Court, from China. It had been sent with an accompanying painting that showed what the flowers looked like. Sonduk, looking at the picture, remarked that the flower was pretty, but it was a pity that it did not smell. When asked why, she answered: “If it did, there would be butterflies and bees around the flower in the painting.” Her observation about the peonies’ lack of smell proved correct – one illustration among many of her intelligence.

The first contact with astronomy and the study of the stars occurred through her tutor, the Chinese ambassador Lin Fang, who was also an astronomer. At the age of 15 she was introduced to Confucianism, which soon became an obstacle to her thirst for knowledge. The Confucian model, indeed, placed women in a subordinate position within the family, which meant that education in general, let alone astronomy, was not considered suitable. Sonduk, however, used to make observations every night and was mostly self-taught. A clash of wills was inevitable.

MOND on Maundy...

Note: I almost didn't blog about this, because the original links at Live Science and Cosmos Magazine lead to "page not found" errors. I was able to find the article on Nature's direct website and provide it here. It's strange both sites had the same bogus links.

Here's a problem: The universe acts like it's a lot more massive than it looks.

Take galaxies, those giant, spinning masses of stars. The laws of motion and gravity tell us how fast these objects should turn given their bulk. But observations through telescopes show them spinning way faster than we'd expect, as if they were actually much more massive than the stars we can see indicate.

Astrophysicists have come up with two main solutions to this problem. Either there's a lot of mass out there in the universe that we can't detect directly, mass scientists call dark matter, or there's no dark matter out there, but there is something missing from our laws of gravity and motion. Researchers call the second proposed solution modified Newtonian dynamics (MOND), which suggests that if the laws are properly tweaked, the universe would make sense without dark matter.

A new paper, published today (March 28) in the journal Nature, provides compelling evidence that there really is dark matter out there and that modifying the laws of physics wouldn't by itself solve the universe's weight problem.

In that study, the researchers found an object that could exist in a universe that has dark matter, but that would be nearly unimaginable in a MOND universe: a totally normal galaxy, one that seems to operate without any dark matter-type forces. [1]

*****

In a study published in the journal Nature, scientists have found a galaxy that appears to contain no dark matter — the unknown material thought to be common in the universe because of its gravitational effect on normal matter.

It was a startling discovery, because galaxies similar to our own Milky Way generally appear to contain 30 times more of the mysterious substance than normal matter, while smaller galaxies can contain up to 400 times as much.

The dark-matter-free galaxy, called NGC 1052-DF2, lies 65 million light years away in the constellation Cetus. It initially caught the attention of astronomers because, while it’s about the size of the Milky Way, it contains only 0.5% as many stars.

“That makes it very diffuse,” says the study’s lead author, Pieter van Dokkum of Yale University, in Connecticut, US. “You can look straight through it. You can see galaxies behind it.”

It was discovered by a special, low-tech telescope in New Mexico called the Dragonfly Telephoto Array, which consists of a bundle of 400-millimetre camera lenses of the same type used by sports photographers, and can scan the sky for large, dim objects. So far, it’s found 23 of them, but NGC 1052-DF2 (the DF is for “Dragonfly”) stood out because it wasn’t just a big, diffuse blob. [2]

Lithium Air Battery...

Posted by Reginald L. Goodwin on March 28, 2018 at 1:03pm

"The new battery design protects the lithium metal anode with a coating of lithium carbonate. That allows lithium ions from the anode to enter the electrolyte while keeping unwanted compounds from reaching the anode. It’s easy to create this protective layer, too. The researchers just had to run a few charge-discharge cycles with a pure carbon dioxide atmosphere, and a crystal mesh of lithium carbonate accumulated." Extreme Tech

The lithium-ion battery has transformed the portable electronics industry and is making inroads into energy storage on the electric grid and electrically powered transportation. Today, research laboratories around the world are seeking to develop beyond-lithium-ion batteries that are even more powerful, cheaper, safer and longer lived.

As reported in the journal Nature, a team of scientists from the University of Illinois at Chicago and the U.S. Department of Energy’s (DOE) Argonne National Laboratory has produced a new design for a beyond-lithium-ion battery cell that operates by running on air (hence, referred to as “lithium-air”) over many charge and discharge cycles. Larry Curtiss, co-principal investigator and Argonne Distinguished Fellow, observed that the team’s article was appealing to Nature because “others have tried to build lithium-air battery cells that run on air, but they failed because of little cycle life.”

“This first demonstration of a true lithium-air battery is an important step toward what we call ‘beyond-lithium-ion’ batteries.” — Amin Salehi-Khojin, assistant professor, University of Illinois at Chicago.

The problem with past technology has been that battery cells tested in the lab required a separate supply of pure oxygen (hence, referred to as lithium-oxygen batteries). As a consequence, a tank of oxygen gas would have to be part of the battery system, making it prohibitive for use in electric vehicles due to space requirements. A lithium-air battery that uses air from outside eliminates this problem.

The key features of the team’s newly developed battery cell are a new protective coating for the lithium metal anode, which prevents the anode from reacting with oxygen and hence deteriorating, and a novel electrolyte mixture that allows the cell to operate in an air atmosphere. In tests under an air environment, this cell maintained high performance during 700 cycles, far surpassing previous technology. According to Amin Salehi-Khojin, co-principal investigator and assistant professor at the University of Illinois at Chicago, “The energy storage capacity was about three times that of a lithium-ion battery, and five times should be easily possible with continued research. This first demonstration of a true lithium-air battery is an important step toward what we call beyond-lithium-ion batteries.”

Scientists, however, still cannot predict with any confidence where pieces of the 10.4-meter long Tiangong-1 station, which is traveling at 17,000 km/h, will land.

The latest estimate from the ESA indicates the station will enter Earth's atmosphere between March 30 and April 3, at which time most of the station will burn up. However, the station is large enough—it weighed 8.5 tons when fully fueled but has since used much of that propellant—that some pieces will very likely reach the planet's surface.

Beyond the fact that the station will reach a final impact point somewhere between 42.8 degrees north and 42.8 degrees south in latitude and probably near the northern or southern extremity of those boundaries due to Tiangong-1's orbital inclination, it is not possible to say where on Earth the debris will land. However, the likelihood of it affecting humans is quite low. Scientists estimate the "personal probability of being hit by a piece of debris from the Tiangong-1" is about 10 million times smaller than the annual chance of being hit by lightning.

Researchers at Griffith University working with Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO) have unveiled a stunningly accurate technique for scientific measurements which uses a single atom as the sensor, with sensitivity down to 100 zeptoNewtons.

(Zepto = 10^-21, or 0.000000000000000000001.)

Using highly miniaturised segmented-style Fresnel lenses - the same design used in lighthouses for more than a century - which enable exceptionally high-quality images of a single atom, the scientists have been able to detect position displacements with nanometre precision in three dimensions.

"Our atom is missing one electron, so it's very sensitive to electrical fields. By measuring the displacement, we've built a very sensitive tool for measuring electrical forces." Dr Erik Streed, of the Centre for Quantum Dynamics, explained.

"100 zeptoNewtons is a very small force. That's about the same as the force of gravity between a person in Brisbane and a person in Canberra. It can be used to investigate what's occurring on surfaces, which will help miniaturise ion trap type quantum computers and other quantum devices.

Graphic Justice

Posted by Stephen Alexander on March 26, 2018 at 6:55am

Graphic Justice is a blog that covers/studies legality and justice within comics and the comic industry. They run conventions and submit academic papers on topics related to comics every year.

They are always looking for submissions, and so I've decided to submit a legal concept article to their site. In my first book Super Humanity, the characters face a tribunal because they executed a prisoner during the Battle of Cleveland. They won because of legal technicalities.

If you've ever wanted to write about comics and legalese together, now's your chance.

The Shattering (repost)...

This was originally posted March 31, 2017. I've updated it with the YouTube video by Channel 4 London on Cambridge Analytica (CNNMoney.com and The Guardian details). The original blog post has aged well.

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 of 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.

Narcissism and Publicity...

I've been away doing grad work and thinking about how I'm going to fund myself this summer. In our current anti-science era, it's a constant concern.

I have other concerns, most recently the Austin bomber and my family in harm's way. The shame is he didn't expire himself before taking the lives of innocent others.

An excerpt of a post from another blog I manage on this subject:

*****

Megan Meier thought that "Josh" loved her. The figment of a neighboring mother's imagination broke up with her and resulted in a sweet girl’s suicide.

Now we have Robert A. Hawkins in what is now the Omaha Mall shooting at the Westroads Mall: nine dead, including Robert and five injured at last count.

I'm old enough to remember when CNN debuted in 1980. Prior to that, HBO had limited showings and television shut down (the "snow" screen in the scene of the movie "Poltergeist") around 11 PM. If you were an insomniac, you REALLY had to work at it.

Not to say there weren't shootings: the UT tower incident in the '60s comes to mind. However, with 24-hour news and the Internet on which you read this commentary, becoming "famous" can happen in nanoseconds at near light speed with the voracious need for copy by the media.

Ironically, "Robert" means "bright and shining fame." I wonder if he knew this when he wrote "I'll be famous" in his suicide note?

In 2004, Nebraska ranked 41 out of 50 states in the rate of suicides recorded: 166 deaths reported in the state at a rate of 9.5. I'm getting this from http://www.suicidology.org/.

From the CNN article linked above, his landlord paraphrased: "He basically said how sorry he was for everything," Maruca Kovac said of the note. "He didn't want to be a burden to people and that he was a piece of s--- all of his life and that now he'd be famous."

Mental health in this country is a phobia, a cousin in the attic no one wants to discuss. We've all got our issues, and they can be exacerbated by the economy, social situations and most importantly, lack of treatment.

It would seem silly if someone broke an arm or the femur in their legs and tried to "play it off" as if nothing hurts. Mind you, I've had my share of hairline fractures as a martial artist that I did the same thing with, but as I get older I'm a little more cautious and check out everything, EVERYTHING with my doctor.

When will we have this attitude about mental health?

Could crime rates be the result of desperate people finding themselves in desperate situations where nefarious criminal activity makes "sense" in warped minds?

Would their be a decrease in wars if we had clear-minded leaders that steered their countries towards peace and alternate energy sources so we're not beholding to despots and dictators to drive our SUVs, pay $3 in gas and turn on a light bulb?

*****

I'm not giving an excuse for the bomber. He paraphrased Alfred Pennyworth's line in Christopher Nolan's The Dark Knight: "some men just want to see the world burn."

Mark Conditt was apparently such a young man. The stereotypical "lone wolf" I'm sure they'll say. "Mental issues" and troubled will be overused metaphors. Never "thug" or terrorism. Never... There's already a stance on "not knowing his motives," despite his initial targets having a distinct hue of Melanin. No word on the motives of the Pulse Nightclub shooter. Not even a word on the motives of the Las Vegas shooter. Nothing...

Perhaps it's simpler than that.

Paul Bloom in 2017 explored it in his New Yorker piece "The Root of all Cruelty?" In it, he comments on the philosopher David Livingstone Smith's book "Less Than Human: Why We Demean, Enslave, and Exterminate Others"; the historian Timothy Snyder "Black Earth: The Holocaust as History and Warning"; "Virtuous Violence: Hurting and Killing to Create, Sustain, End, and Honor Social Relationships" by anthropologist Alan Fiske and psychologist Tage Rai; "Down Girl: The Logic of Misogyny," by philosopher Kate Manne, "One Long Night: A Global History of Concentration Camps," Andrea Pitzer and starts his piece with the apropos cultural Netflix series Black Mirror all to come to a single conclusion:

Humans suck.

It is not that the Austin bomber or any other previous to this heinous act lacked an appreciation for the diversity of humanity. It may be that he realized despite his Internet screeds to the contrary, gays, women, minorities are all human...he just didn't care that they are. He "defined his stance" on his personal blog for the world to see. I've noted no news agency, save the Dallas Morning News has reported on it.

Anyone in a free society is free to hold any opinion that s/he wishes as long as it doesn't impact others negatively.

But for a malignant narcissist, that's not good enough. It is the "other" that's responsible for their pain. It is the "other" that must suffer.

Symptoms

Narcissistic personality disorder includes symptoms such as poor self identity, inability to appreciate others, entitlement, lack of authenticity, need for control, intolerance of the views/opinions of others, emotional detachment, grandiosity, lack of awareness or concern regarding the impact of their behavior, minimal emotional reciprocity, and a desperate need for the approval and positive attention of others "How to Recognize a Malignant Narcissist," Rhonda Freeman, PhD, Psychology Today.

Malignant narcissists on a personal level can be associated with physical violence. I'm not sure if it's been correlated with domestic terrorism. However, we have never given one the nuclear codes before, nor investigated them for collusion with a hostile power; nor seen them sued by a former adult film star, an ex-playboy playmate and a former contestant on "The Apprentice" as well as many other women for sexual assault. Nary a peep from the religious right, so animated during the Bill Clinton era.

And some with Napoleonic delusions of grandeur might be willing to burn the house down while standing in it. As the walls close in, he may use his vast powers to rain down nuclear Armageddon on the human species, versus doing a "perp walk." He might kill a cellist that was a model student and hoped to be a medical doctor. Now that dream is dust. Maybe Conditt knew him, and was jealous that the cellist, Draylen Mason was African American and his currency of whiteness only allowed him to take a few classes at Austin Community College. Whether he lived or died (the latter now reality), he'd be "famous." Pflugerville, Texas was shut down after his confirmed death in "an abundance of caution" to a discovered package. The currency of whiteness could historically get you any job in the idealized past free of "others" - the unspoken, underlying id of #MAGA. Maybe Conditt was expecting such luck, and resented it not working out for him. Even one you're hopelessly unqualified for - the US presidency as case-in-point, in probably the last, best example for all time of white male privilege.

This currency is a dividend we're all paying, whether we like it or not.

Sadly, there will be another, as there were over 600 similar threats after the Parkland shooting, that will try to one-up Conditt.

The difference of my youth to now is we're surrounded by a ubiquitous deluge of information: television, radio, satellite radio, Internet, blogs and social media apps, which can be accessed on cell phones, computers and I-pads.

I grew up in an era of ABC, CBS, NBC and a few UHF stations. There was no CNN or HBO. Television stations signed off at midnight. News wasn't instantaneously spread around. It took time. There wasn't a vast stage to visit cruelty on so many innocent "others"; instant fame and infamy for twisted psyches.

We've always had malignant narcissists. They just didn't have as many platforms for amplification and echo of their ego, mayhem and fame... or, the nuclear codes.
