Biomorphs...

Graphene-glass bimorphs can be used to fabricate numerous micron-scale 3-D structures. CORNELL UNIVERSITY

Topics: Biophysics, Chemistry Nanotechnology, Robotics

A team of physicists from Cornell University in the US has developed electricity-conducting, environment-sensing, shape-changing robots the size of a human cell.

The robots – described in the journal Proceedings of the National Academy of Sciences – are made from atomically thin layers of graphene and glass. Known as biomorphs, the tiny machines bend when exposed to stimuli including heat, chemical reactions or electricity. They can transform in a fraction of a second from two dimensional planes into complex three-dimensional forms such as tetrahedra and cubes.

Team member Paul McEuen says the biomorphs are designed as carriers for even smaller, but potentially very powerful, bits of photonic, electronic or chemical kit.

“We are trying to build what you might call an 'exoskeleton' for electronics,” he says. “Right now, you can make little computer chips that do a lot of information-processing, but they don't know how to move or cause something to bend.”

Theory from Turkish Prison...

Ali Kaya, Nature

Topics: African Americans, Civil Rights, Commentary, Cosmology, Martin Luther King

As we are juxtaposed between the celebration of Dr. King and the advent of African American History Month, post the (I did not watch) SOTU address from a president* that thinks "hole," not "house" was the insulting part of his epithet, it's healthy to be reminded this dark, fascistic and authoritarian march is global. The world is smaller with more people in it competing for resources, and there are those reptilian brains that wax nostalgic for an idyllic past that never was, but determined to take us all back there, wherever and whatever "there" is in their Gollum minds. It is also sobering to remind ourselves that democratic republics are both fragile and without proper care: fleeting. Dr. Kaya's courage should inspire us all.

Atlantic Journal Constitution: Letter From Birmingham Jail (cultural reference to post title).

Thousands of academics in Turkish universities stand accused of either having supported terrorism or the attempted coup against President Recep Tayyip Erdoğan in July 2016. Theoretical physicist Ali Kaya is one of them. He was arrested three months after the failed coup and held for more than a year before his trial took place. On 20 December, a court declared him guilty of being a member of a terrorist organization and sentenced him to six years of imprisonment — but released him early owing to the time he had already served in prison while awaiting trial. Kaya says that he is innocent and is appealing against the verdict. In the meantime, he has been suspended from his academic post, and he has yet to learn whether his university, Boğaziçi University in Istanbul, plans to fire him or to await the outcome of the appeal.

Kaya says that while in prison, he kept his sanity by continuing his work on fundamental topics in cosmology. He wrote three research papers during his incarceration, on topics including inflation theory and cosmological perturbation theory. After his release, he posted the papers on the preprint server arXiv. Each contains a footnote that he dedicates to his friends in jail “who made my stay bearable at hell for 440 days between 7.10.2016 and 20.12.2017. I am also indebted to the colleagues who show support in these difficult times.”

Nature interviewed Kaya by Skype about his experiences.

What access did you have to research materials while in the prison?

Of course there was no Internet. Nothing digital — not even a pocket calculator — was allowed. No books could be brought in. Nothing in a foreign language was allowed in the jail. One of my students Google-translated some research papers for me into Turkish, but they were held back on suspicion that they included secret codes — presumably because they contained so many equations.

I worked up the research ideas I had already in my head before my arrest. Of course, it took much longer than it would have done if I had been at my computer. I had to start from basic formulae and derive things myself.

But time is something you have plenty of in prison. OK, I could not do ground-breaking work, but I think the papers I produced are solid, and I expect to get them published in good journals.

Another post Black Panther must see for me is Madeleine L'Engle's A Wrinkle in Time, THE DISNEY MOVIE. I must confess that this project has my heart for two reasons. First is the FACT that this book got me to literally READ on the level of pure enjoyment as a elementary school child. It was my FIRST Science Fiction story ever, was relatable as the main character was MY age at the time. A book was assigned to me by a teacher, a black woman named Mrs. Garrett whom at the time was one of the many teachers (Black) at my school in Oakland, Cali whom I believe took her job for teaching young black children SERIOUSLY. She had a reading list to which we were given a choice of many books at 3rd/4th grade level and I out the blue choose this one just to get her off my back. After forcing the first few chapters, my attention begin to focus when the group encountered the tesseract. I read the entire book in a week and it inspired me to begin to WRITE my own Sci Fi story.

SECOND reason I must see this is that it is directed by "QUEEN SUGAR" director Ava DuVernay my film shero. This is her time showing her hand at a pure IMAGINARY direction which looks better than AMAZING YO! I am used to her work with the REAL and the TRUE which has (to me) all been cinematically OUTSTANDING. Now this YO! Is 2018 going to be the year I have to create a budget for MUST SEE movies? At least in the first three month is looks like..... Enjoy

Oh Yeah FYI: "A Wrinkle in Time", the winner of the 1963 Newbery Medal, celebrated its 50th anniversary in 2013 and continues to thrive. It holds the ranking by many critics as one of the most frequently banned novels of all time.

Nano Magnets and Light...

Topics: Electromagnetism, Optical Physics, Nanotechnology

Magnetic nanoparticles with chiral distortions in their crystal lattice provide an unprecedented degree of control over circularly polarized light. The effect, which was demonstrated by the nanoparticles embedded in a transparent gel and exposed to a magnetic field, can be understood thanks to careful consideration of the magnetic field of the photons, in addition to the familiar electric field.

Where magnetism and chirality (a lack of mirror symmetry) overlap there are often intriguing discoveries. These two concepts are fundamental to the advancement of spintronics, chiral catalysis and magneto-optics. Much of the research in this field aims to enhance the interaction between electrons in matter and the (often ignored) magnetic field of a photon.

A recent and very successful example of such an attempt is the work from Nicholas Kotov and collaborators in the University of Michigan, USA, and the Federal University of São Carlos, Brazil. The researchers created a material comprised of magnetic nanoparticles (NPs) with a chiral or twisted crystal structure encased in a transparent gel. This chiromagnetic gel responds to circularly polarized light with a sensitivity 10 times greater than previously observed in similar non-magnetic composites.

Rewind...

Image Source: Movie Pilot. Where's a benevolent Kryptonian when you need him?

Topics: Existentialism, Nuclear Power, Politics, Star Trek

One of the premises of Star Trek is we'll overcome our technological infancy, our myriad differences with one another, and somewhat Pollyannish: nuclear war. That we'll survive - in the spirit of the Drake Equation - not just long enough to communicate, but to become a space-faring species.

Some of that optimism has a limit: a 280-character limit.

The president* can launch a thermonuclear first strike or counterstrike presently without any consultation with Congress. A relic of the Cold War with the former Soviet Union, speed and efficiency was encouraged when we had more rational actors in possession of the nuclear football. It takes about 5 minutes for ICBMs; 15 minutes for submarine launched missiles to be deployed once the order is given. In the event of negative findings from the Mueller investigation, he could literally have "nothing to lose." There are no calling these "dogs of war" back once they're off-the-porch.

The world moved closer to an existential catastrophe this year as the threat of nuclear warfare escalated, bringing the symbolic Doomsday Clock two minutes away from midnight, the Bulletin of the Atomic Scientists said Thursday.

The move of the Doomsday Clock to two minutes away from midnight, the symbolic time at which the planet meets a world-ending disaster, represents a 30-second jump from last year. It is the closest the planet has been to midnight since 1953 when the U.S. and the Soviet Union were testing hydrogen bombs.

To call the world’s nuclear situation dire is to understate the danger and its immediacy,” said Rachel Bronson, president of Bulletin of the Atomic Scientists.

Hathor Bastet Sekhmet (part 1)

What is it Bastet ? It’s too earl…”

Before she could finish her phrase, the rays of the dawning sun going through the window of her bedroom had already dazzled her. Her cat sat on the little place she could find on her mistress’s bed next to the pillow where she laid her head. “Always the same with you, never letting me oversleep a little, but you still get to sleep whenever you like while I have to heal our patients during the day.” Bastet seemed more interested by Bounefer’s locs than her remarks and reached towards them with her paws. Bounefer didn’t give the little creature a chance to get to the prize as she started stretching her arms and was now sitting while still yawning. Bastet’s disappointment was not for long, as she jumped straight on her mistress’ thighs and sat there. Bounefer started caressing the black cat behind her pointy ears. She named her Bastet in honor of the Netjeru Bastet, often represented as a female cat, and who brings joy in one’s home. “You can’t get enough of me carrying you like a baby every morning”, said Bounefer as she stood up to get out of her room, “you must be hungry by now, but first let’s thank the ancestors and the spirits for this new day.”

As she walked through the corridor, with the mewing Bastet on her arms, Bounefer could occasionally hear faint snores from patients of the hospital. “We’ve had a lot of patients lately, far too many”, Bounefer thought. “Keeping the city healthy is our duty, teach the people how to eat well and stay healthy, the less patients we have in this hospital, the better”, she would often tell the nurses working with her. Those above normal numbers of patients were due to the recent troubles made by the rebels of the Tehenu people, whose ancestors were defeated centuries earlier by the great pharaoh Djehutymessou Neferkheperou, who extended the empire of Kemet to its largest size, successfully defending it from the aggression of both the Tehenu of the east and the People of the Sea from North and West. The Tehenu seemed to never have forgotten or forgiven this defeat, and now even though those integrated could do business or own land for many generations, some of them were now attacking innocent civilians, looting and causing insecurity in Denderah, the town of the Netjeru Hathor. The day before, Bounefer and her nurses had to welcome and treat 15 people wounded in an attack caused by bandits. For Bounefer, the claims of the rebels were merely a pretext. She indeed recently treated a lot of innocent Tehenu who were wounded by similar senseless acts of violence, which to her was proof that all this violence was committed for the selfish interest of a few among the Tehenu. Just like many people in Denderah, she suspected Psammetic, a fat rich cupid merchant, as the instigator of those acts, in the shadows of course, as such a man would operate. Psammetic’s wealth made him want more and more, like rising to political power by taking office as governor of Denderah. However the authorities had reasons to believe he had ties with the Assyrians, an enemy kingdom. “Yet they do nothing”, would Bounefer often complain. This and the fact that this man had the nerve to offer money to her in exchange for spending a night together was enough for Bounefer to be filled with disgust at the thought of Psammetic.

How can the authorities fear one traitorous man so much, the Assyrians are indeed strong, but we are Kemet! Well at least they understand the necessity of maintaining this hospital secure.” At that time she had accepted to take the money from the merchant. “With all his wealth, he must definitely give back to the city!” Bounefer cunningly thought. However the night when Psammetic sent his men to escort his “prize”, those were met by the hospital guards who beat some manners into them so hard that they never dared coming back. Psammetic felt that as a humiliation, but since the hospital was guarded on the governor’s orders, he couldn’t just take Bounefer by force. This daring act gave much satisfaction to Bounefer, but now she felt annoyed by the fact that the guards insisted on accompanying her whenever she went out, either to the market or to get some other business done, or to simply have a walk and get some fresh air. She wasn’t naïve though as she could clearly sense some were attracted to her. “As if the two of us needed security from men who wouldn’t even dare to face a fat cupid merchant and rid our city from those rebels, this is ridiculous, isn’t it Bastet?” said Bounefer while kissing Bastet’s on her tiny head. The cat simply mewed back as to show her agreement with her mistress.

To get to the shrine, Bounefer had to walk across the large courtyard of the hospital under her responsibility, coming from the building where both nurses and patients would sleep. Bounefer took a left detour to get in a smaller building. As she entered through the door, she walked past the medicines room where her assistant Heqet stood, not noticing yet Bounefer’s presence. Bastet dropped from Bounefer’s arms as she continued to get to the kitchen in the next room. There she filled a jar with some milk, then filled a smaller one with water. Taking a filled jar with each hand, she moved back towards the medicines room. Heqet, who had not noticed her at first, was now fully aware of her presence thanks to Bastet sitting next to her feet. The young woman’s hair stood up on her whole head, holding somehow a wooden comb which handle rested on her forehead. She looked at Bounefer with her brown eyes full of excitement.

Hotep Seba, have you slept well?” Seba is a title of respect given to one’s teacher.

Shemhotep Heqet, I have, thank you. I could have slept a little more though, but I guess Bastet is the one who decides about that!” Bounefer replied with a chuckle, to which Heqet replied herself with an endearing smile looking at the cat playing with her white linen dress. “I see you’re still working on those plants mixtures, I hope Bastet hasn’t distracted you too much”.

Oh not at all, I enjoy having her around, besides I finally found the right dosage of bissap and nebeday powders to make the already treated patients recover faster and have their immune system as good as new.”

You’ll never cease to amaze me, keep up the good work then, is our patients’ breakfast ready?”

Yes it is, as soon as they wake up, I will take it to them”

Good, I’m going to the shrine, then I will go check how well our stubborn soldier is doing. If there is anything wrong, don’t hesitate to call me”

I will, by the way you and Shemai have been rather close lately, that’s unlike you Seba ”, teased Heqet while still smiling.

Come on don’t be silly”, laughed Bounefer, then turning to Bastet, she whistled, which made the cat follow her.

Heqet was her most reliable and gifted nurse. Bounefer had appointed her as her personal assistant for that reason. Not only was her knowledge of medicinal plants incredible for her young age, her sensitivity and compassion towards patients stood out compared with the others and Bounefer herself. Some former patients came back offering her gifts of gratitude after being cured due to the little things she would help them with like walking around the courtyard and letting them lean on her for those whose legs hurt. Some male patients would even go as far as to suggest something beyond her nursing duties, which she would often take as a joke and laugh about. “You’re sometimes too kind for your own good, don’t encourage patients’ foolishness ” would Bounefer often say to Heqet. Despite these admonitions, Bounefer had great trust in Heqet. Bounefer had received a substantial amount of gifts herself, and those weren’t only to give her credit for putting this hospital in place. Her dazzling beauty was renowned in Denderah, as many men would tell her beauty rivaled that of the Netjeru Hathor herself, which she served. Her smooth and very dark skin and her piercing black eyes had hypnotized many. But still all her suitors were met with a more than clear rejection.

Getting back to the courtyard, Bounefer noticed a black muscular man with bandages on his chest doing what appeared like acrobatic dancing moves. With a sigh, she continued walking towards the shrine while Bastet ran to get near the acrobat.

Once she reached the shrine, she kneeled and placed the jars next to her. She bended over touching the grass with her head thanking the Creator, who had many names such as Atoum, Ptah or Neith for implanting her/his vital force on everything in this universe. She straightened her back, repeating the same movement, this time thanking the spirits or Netjeru as they were called, for their involvement in maintaining balance in the universe, the essential role of Ma’at. She particularly thanked Hathor, Bastet and after some hesitation Sekhmet, those Netjeru who she felt the closest to. While straightening her back yet again, she looked at the little wooden statue of Sekhmet put on the shrine. The Netjeru was depicted as a woman with the head of a lioness, her eyes seemed to penetrate into Bounefer’s soul, which made her feel uneasy. Sekhmet was as much feared for her uncontrollable ferocity and murderous bloodlust as she was praised for her ability to heal diseases. Bounefer knew about this complex duality all to well. “Why me? Why do I have to carry such a curse?” She thought, while looking at Sekhmet. She then proceeded to greet the Ancestors, both from her family and those renowned in Kemet for their wisdom and knowledge of the medicinal art. Among the latter, there was of course Imhotep, the greatest of them all. After properly greeting all those spiritual entities, she then proceeded to pour libations as offerings to them, with the milk and water she had brought in the two jars. She poured all the water and half the milk on the grass just in front of the shrine. As usual, the last drop of milk honored her grandmother, “To you, my protector Nefertari Bounefer!” The other half of the milk would be for Bastet. In a curious way, Bounefer considered this milk for Bastet as an offering to Hathor, in her joyful feline form, due in no small way to the special nature of the cat she had received from her grandmother. “You will endure a lot of hardships, let her be your faithful companion through all of those”, the old lady had told her while putting the tiny black kitten on her little arms when she was still a young girl. The black cat was born on her seventh birthday. Bastet had never left her since, outliving all other normal cats. They were twin souls, their fates tied forever.

Bastet ran in circles around the acrobat. The unusual movements attracted her attention. Shemai had with him a little red ball he threw to the cat for her to play with. Bastet, always ready for a new distraction, started moving the ball back and forth between her paws. Shemai moved left and right, his legs leaving a cross shaped imprint on the sandy, yet hard ground. He moved his hands according to the position of his legs, placing the elbow at the side of his rear leg almost in front of his chin while the other arm would keep him in balance in a guarding stance fashion. He would adapt the rhythm of both his movements and his breathing to the imaginary rhythm of drums that played in his head. From time to time he would launch a kick with a stretched out leg drawing a circle in front of him while changing his stance, and chain it with another similar kick with the other leg and in the same direction. Or he would simply change his stance as to dodge some imaginary attack coming from both sides. As he followed one of those dodge stances with a cartwheel, Bastet’s ball unexpectedly flew towards his head when he already had one leg in the air. Bastet’s overexcitement with her new toy made her throw it towards the intriguing dancer. Shemai skillfully stopped his cartwheel motion, maintaining himself balanced on his hands and with a little headbutt, threw the ball back to his feline playmate. He was now doing pushups with only his hands touching the ground while arching his back and successively bending and stretching his legs.

Bounefer witnessed the whole spectacle while heading to the high statue of Hathor in the middle of the courtyard. The statue represented the Netjeru Hathor with two horns on her head carrying a disc representing Rê, the sun. On her left, the sculptor had placed a tall cat in a sitting position and whose head was at the level of the woman’s generously curvy hips. On her right stood a cobra at the same height as the cat. The cobra probably suggested the role Hathor could take as Ouadjet, protector of Rê and all pharaohs, the latter would always put her on top of their forehead. The cat of course symbolized the two feline aspects of the enigmatic feminine entity, the cute playful and protective Netjeru Bastet, and of course Sekhmet, the dangerous lioness whom, according to the legend, Rê unleashed to punish the unruly men, in the beginnings of humanity. Bounefer took a little bowl at the feet of the cat statue, filled it with the rest of the milk, and went towards her cat, still playing with the red ball. Bastet immediately stopped her little game as soon as she felt her mistress approaching, somehow remembering she had to fill her belly. She already started drinking when Shemai finally stopped his pushups. Crouching next to her cat, Bounefer stared disapprovingly at Shemai, her current patient.

You haven’t fully recovered yet, I told you to rest, you were barely alive a week ago”

Hey I can’t help it if you’re a good healer Nefri” replied Shemai with a sardonic smile.

How did you call me?”

Nefri, it’s a cool nickname isn’t it?”

No it’s not, and stop it already with these moves, your breathing is already getting irregular” scolded Bounefer, while Shemai put himself back in his guarding stance.

I think that may have less to do with my training than your presence, and it’s called ginga by the way” Shemai retorted with a teasing smile. He then walked and sit on the bare ground right next to Bounefer and Bastet.

Whatever!” Bounefer couldn’t help it as a faint quick smile changed her normally stern looking face. It was barely noticeable and by the time she turned towards her sitting patient, she already shifted back to her serious face.

Was that the dancing martial art you told me about?”

Yes, exactly, I usually practice every day, it helps me stay fit, and I feel less nostalgic about being far from Kush.”

You put too much weight on your front leg whenever you’re doing this ginga thing, that puts too much stress on your knees, practice long enoug and they’ll eventually wear off.”

Really! It’s true sometimes my knees hurt a little” nodded Shemai, “that’s very perceptive of you, it’s only the first time you saw me practice, and you’re already making remarks just like my former master”

I can’t help it if I am an experienced healer!” teased back Bounefer.

Shemai chuckled, “Sure you are, I bet there is even more to you, there is something mysterious about you Nefri!”

Stop calling me that!” sighed Bounefer, and after a brief pause “Let me check your wounds”

She then proceeded to examine his torso. When it came to diagnosing patients through touch, no one could rival Bounefer. Her heightened senses allowed her to even understand internal organs malfunctions. This skill revealed extremely helpful for holistic healing, as she could somehow see through all the connections between the body’s organs. This way she saved many patients, who apparently only had benign symptoms, from potentially very dangerous diseases, as she dialogued with their body to trace the real source of their problem. In the case of Shemai however, it was quite simple, he was in rather good health now as his handsome appearance would suggest. The only reason he was brought to Bounefer is because an arrow had pierced his lung, while he was fighting singlehandedly a group of Tehenu scoundrels threatening to loot and wreak havoc in a near district. One of the locals brought him to her, and Shemai had been very lucky that day, since the arrow pierced merely an inch away from his heart.

You’re really blessed to have been brought here in time” she told him, while checking his bandages

Indeed. But things would have turned out differently if I were not the only one fighting though. I think you Kemites are a little too kind with those Tehenu rebels. In Kush they would have been dealt with by now.”

Well that’s definitely an insult coming from someone who confuses dancing and fighting!” said Bounefer mockingly.

Shemai started laughing heartedly, but a brief pain struck him right on his chest wound, “Ouch!”

Easy, easy now, breathe calmly”, Bounefer whispered, still checking the lung wound for any possible complication.

Tsk, don’t be fooled by appearances, this dance as you say can be very useful in real situations”, he said after taking a deep breath. Besides, you of all people should know one thing could be many at the same time, as you are a servant of Hathor of the thousand forms.”

Hearing those last words, a shadow went across Bounefer’s face as unpleasant memories went through her head.

Did I offend you?” asked Shemai, a little worried.

What? No, not at all, it’s nothing!”

Okay, then. Are you done with checking my health, or do you enjoy having your hands on quite a handsome man’s chest. Not that I have any problem with it.”

You’re impossible” laughed Bounefer, “Go back to your room now, order from your healer. I’ll come back later to change your bandages they are all wet with your sweat.”

All right, all right! I’m going back.”

Bastet had already finished her milk, and as usual she took the bowl with her mouth and placed it right under the cat statue. Afterwards, the cat ran back to her mistress, mewing happily, and was welcomed with a tender smile. Taking her cat in her arms, Bounefer watched as Shemai walked away from them. “What a brave man, unlike most in this city”, she thought to herself. As she brought Bastet closer to her breasts, facing her, the cat simply started playing with one of her locs. “The two of us can’t have a normal life, can we? No man in this world would be safe with us” Bounefer whispered, “At least I can share the burden of this curse with you, I would have gone insane otherwise.” Bastet didn’t seem to pay attention, focusing on her new game. Bounefer stood there for a while, remembering the words of her now dead grandmother : “You can only be with a man who can stop Sekhmet herself.” “Grandma, there is no such man”, Bounefer thought with a sad look on her face.

As a species, most of what we have come to know as science and develop its different branches as well as engineering comes from our hunter-gatherer ancestors in Africa or Pangaea, dependent on the state of our sphere's geological evolution.

I'm an anomaly as a graduate student. I'm "non-traditional" in that I started this program on my 55th birthday (my children are adult men). I'm an African American having majored in physics and again majoring in a STEM field (Nanoengineering), which is interesting in a place LIKE America.

America: Where it's important to "debate" the efficacy of creationism vs. evolution; whether the universe is 6,000 or 13.8 billion (at least as far as our telescopes can currently see) years old. Where Bill Nye the Science Guy can have a public "debate" with Ken Ham of the morbidly performing (monetarily) Creation Museum. Where the COSMOS reboot can have online trolls and will likely have them again in March. Where anti-vaccine advocates finally got a president* that will let them affect the CDC notion of herd immunity and might kick off the next pandemic, courtesy of the USA.

AS RESEARCH FOR his latest novel, The Quantum Spy, Washington Post reporter David Ignatius spoke with some of the world’s leading experts on quantum computing, which led him to believe that we may see a working quantum computer in the next five years.

“Initially what I would hear back from technologists was, ‘it’s fascinating if it works,’ and I hear more now ‘fascinating when it works,'” Ignatius says in Episode 291 of the Geek’s Guide to the Galaxy podcast. “There’s a sense that these problems probably can be solved.”

The downside is that a quantum computer would be the cyber warfare equivalent of a nuclear bomb, which means the US government is often reluctant to let foreign scientists work on the most promising research. It’s a system that can slow down progress due the lack of ‘smart Americans,’ as one character in the book puts it.

“The number of American citizens who can do very high-end research who also can easily get security clearances is limited,” Ignatius says. “The ability of our schools to produce American students at a world-class level, that’s an important national challenge.” [1]

...lack of 'smart Americans'...ouch!

I'm a product of Sputnik scaring the bejesus out of America and a slew of money was put in public education...fast, to catch us up with the Russians (you know, back-in-the-day when we weren't colluding with them to topple our federal republic). The country invested in education from a republican president, Dwight D. Eisenhower, and continued through successive administrations regardless of party affiliation, the ONE thing at the time we could all agree on as a country.

Now, stupidity is a virtue. To be too smart is a liability, especially if you're female, a minority or other-than white Anglo Saxon Protestant (WASP). It's the equivalent of barring slaves from reading the Bible (the whole "setting the captives free" thing), and some actively discouraging their fellows from the dangers of learning. And just for icing on the cake, the previous year's Doomsday estimate of two one half minutes has been moved up by 30 seconds: it is now two minutes to midnight. As a former high school nerd that used to be terrorized by the football athletes and the Barbie-perfect cheerleaders, it appears the "beautiful people" have won, dangerously dumb as they are.

It also appears fear - a great motivator sales agents, especially in the home security industry use to the HILT - has triumphed. Part of the attraction to Creationism, Intelligent Design and "Alternative Facts" is that actual facts shake strongly held beliefs that humans tend to challenge to right their cognitive dissonance. It never occurs that the text of several cultures was limited by the technology of the times. For example, "cattle on a thousand hills" is a specific reference to enormous size, usually associated with wealth. The etymology of the word "million" did not enter the lexicon until circa the 14th Century. From the link at Etymology online: "The ancient Greeks had no name for a number greater than ten thousand, the Romans for none higher than a hundred thousand. "A million" in Latin would have been decies centena milia, literally "ten hundred thousand." To say to an ancient culture: "King David was a millionaire and his son Solomon was a billionaire" would have had no meaning to the audience at that time.

A great analogy by Joe Madison on Sirius XM used a petri dish to describe culture: when you place a bacterial sample in the petri, a culture usually grows, his point being whatever you encourage will eventually manifest. Again, when you deal in nonsense, you get it. I'd be greatly confused as a young person in public education now. WHAT exactly do you want me to study? based on what our culture currently values: actors, athletes, charlatan ministers fleecing their flocks with promises of spiritual "trickle-down" wealth; not doctors, scientists or engineers. The careers of the future necessarily involves hard, demonstrable FACTS. International industries will follow the brain power - away from us, thus other places will see a rise in their middle classes while ours struggles, stumbles and falters ever downward. The peddling of the alternative type [of facts] is undermining our trust in institutions like our intelligence services and our government. Anarchy only sounds noble, and it doesn't eventually work itself out to Nirvana. It's usually - by the evidence of historical, documented FACTS - a failed state.

"One of the things taken out of the curriculum was civics," Zappa went on to explain. "Civics was a class that used to be required before you could graduate from high school. You were taught what was in the U.S. Constitution. And after all the student rebellions in the Sixties, civics was banished from the student curriculum and was replaced by something called social studies. Here we live in a country that has a fabulous constitution and all these guarantees, a contract between the citizens and the government – nobody knows what's in it...And so, if you don't know what your rights are, how can you stand up for them? And furthermore, if you don't know what's in the document, how can you care if someone is shredding it?" [2], [3]

A technique to create multi-coloured 3D images that can share space with physical objects has been developed by researchers in the US. The work is at an early stage, but it offers several potential advantages over currently available techniques for creating 3D images such as holography.

The technology used by the android R2D2 to project the 3D video footage of Princess Leia pleading "Help me, Obi-Wan Kenobi: you're my only hope" into thin air was never explained in the film Star Wars. Scientists, however, have invented several technologies capable of producing the impression of 3D images. The best known, and most widely used is holography, in which a 2D surface sends light to the eye in such a way that the brain reconstructs this light as having come from a 3D object. Unfortunately, this optical illusion only works for a fairly narrow range of viewing angles: "Holograms and displays like them are based on 2D modulating surfaces that have to be looked at like a TV screen," explains Daniel Smalley of Brigham Young University in Utah, "You always have to be looking into the screen to see it."

In a volumetric display, however, the light originates from where your eye sees the image. Such displays have several advantages over holograms. As the image does not rely on an optical illusion, for example, it is unaffected by the viewing angle. "You can be lying flat on the ground and you can see what's coming up out of the display," says Smalley. Furthermore, it is (at least in principle) possible to wrap the image around the viewer or another physical object.

The Truth Always Surfaces

I remember a line from the X-Files. One of the Navajo characters said something like "truth never stays buried. it always finds a way to the surface."

In this news article, literally.

https://www.washingtonpost.com/news/retropolis/wp/2018/01/24/the-last-u-s-slave-ship-was-burned-to-hide-its-horrors-a-storm-may-have-unearthed-it/?utm_term=.0cb6c2482f4d

In the summer of 1860, half a century after the United States banned the trans-Atlantic slave trade, Capt. William Foster sneaked 110 African slaves into Mobile, Ala. — and knew that the floating evidence of the illegal deed could get him killed.

The trip was more part of an obscene bet than any sort of profit-making scheme, but the Clotilda, the ship that made the months-long journey, held the telltale signs that it was an illegal slaver: containers for water and food, and the lingering stench of urine and feces and vomit and blood.

If caught, Foster and his crew could be imprisoned or executed, so they found a remote section of the Mobile-Tensaw Delta and torched the ship, igniting a mystery that would endure for a century and a half.

What happened to the Clotilda, the last ship to bring slaves to the United States?

The First Black Holes...

Topics: Astrophysics, Black Holes, Cosmology, General Relativity

How could the oldest black holes have grown so big so early in the universe?

Imagine the universe in its infancy. Most scientists think space and time originated with the big bang. From that hot and dense start the cosmos expanded and cooled, but it took a while for stars and galaxies to start dotting the sky. It was not until about 380,000 years after the big bang that atoms could hold together and fill the universe with mostly hydrogen gas. When the cosmos was a few hundred million years old, this gas coalesced into the earliest stars, which formed in clusters that clumped together into galaxies, the oldest of which appears 400 million years after the universe was born. To their surprise, scientists have found that another class of astronomical objects begins to appear at this point, too: quasars.

Quasars are extremely bright objects powered by gas falling onto supermassive black holes. They are some of the most luminous things in the universe, visible out to the farthest reaches of space. The most distant quasars are also the most ancient, and the oldest among them pose a mystery.

To be visible at such incredible distances, these quasars must be fueled by black holes containing about a billion times the mass of the sun. Yet conventional theories of black hole formation and growth suggest that a black hole big enough to power these quasars could not have formed in less than a billion years. In 2001, however, with the Sloan Digital Sky Survey, astronomers began finding quasars that dated back earlier. The oldest and most distant quasar known, which was reported last December, existed just 690 million years after the big bang. In other words, it does not seem that there had been enough time in the history of the universe for quasars like this one to form.

Many astronomers think that the first black holes—seed black holes—are the remnants of the first stars, corpses left behind after the stars exploded into supernovae. Yet these stellar remnants should contain no more than a few hundred solar masses. It is difficult to imagine a scenario in which the black holes powering the first quasars grew from seeds this small.

To solve this quandary, a decade ago some colleagues and I proposed a way that seed black holes massive enough to explain the first quasars could have formed without the birth and death of stars. Instead these black hole seeds would have formed directly from gas. We call them direct-collapse black holes (DCBHs). In the right environments, direct-collapse black holes could have been born at 104 or 105 solar masses within a few hundred million years after the big bang. With this head start, they could have easily grown to 109 or 1010 solar masses, thereby producing the ancient quasars that have puzzled astronomers for nearly two decades.

The question is whether this scenario actually happened. Luckily, when the James Webb Space Telescope (JWST) launches in 2019, we should be able to find out.

...or vice-versa. This was alluded to in the novel and movie The Martian.

WASHINGTON (Reuters) - Initial tests in Nevada on a compact nuclear power system designed to sustain a long-duration NASA human mission on the inhospitable surface of Mars have been successful and a full-power run is scheduled for March, officials said on Thursday.

National Aeronautics and Space Administration and U.S. Department of Energy officials, at a Las Vegas news conference, detailed the development of the nuclear fission system under NASA’s Kilopower project.

Months-long testing began in November at the energy department’s Nevada National Security Site, with an eye toward providing energy for future astronaut and robotic missions in space and on the surface of Mars, the moon or other solar system destinations.

A key hurdle for any long-term colony on the surface of a planet or moon, as opposed to NASA’s six short lunar surface visits from 1969 to 1972, is possessing a power source strong enough to sustain a base but small and light enough to allow for transport through space.

“Mars is a very difficult environment for power systems, with less sunlight than Earth or the moon, very cold nighttime temperatures, very interesting dust storms that can last weeks and months that engulf the entire planet,” said Steve Jurczyk, associate administrator of NASA‘s Space Technology Mission Directorate.

Nanosensors...

Researchers in the US have developed nanosensors that can be directly inserted into a cell’s lipid membrane and be used to measure membrane potential. The devices, which are based on inorganic semiconductor nanoparticles, could potentially record action potentials from multiple neurons as well as electrical signals on the nanoscale – for example, across just one synapse.

Thanks to recent advances in inorganic colloidal synthesis, researchers can now make functional semiconductor nanoparticles whose size, shape and composition can be precisely controlled. Such nanoparticles can be used in applications as diverse as optoelectronics, biological imaging, sensing, catalysis and energy harvesting.

These nanomaterials can also be combined with biological cells to make highly sophisticated hybrid nanomaterials that outperform their purely biological counterparts. Until now, however, incorporating these particles into cell membranes has proved difficult. This is because they are often too big and have surface properties that can lead to non-specific binding on cell membranes. What is more, inserting nanoparticles into membrane bilayers is further complicated by the fact that their surfaces need to be functionalized so that the particles are inserted in the correct orientation.

“We must live together as brothers or perish together as fools.” Reverend Dr. Martin Luther King, Jr.

Tomorrow...is the anniversary of what would be known first as "the carnage" after his inauguration speech, then accented with "alternative news" as truth itself was made malleable, "fake news" as he attacked the fourth estate; feverish, septuagenarian bowel movement tweets (at least he's regular) and "covfefe."

“Welcome to the dawn of a new, unified Republican government,” said a beaming Paul Ryan, just over a week after Donald Trump’s improbable 2016 win delivered control of the White House, the Senate, and the House of Representatives to the GOP for the first time in over a decade. Eyebrows arched in an expression composed of equal parts glee and incredulity, the House speaker allowed himself a brief moment of public self-reflection. “It feels really good to say that, actually.” [1]

One year later...we're deep in the throws of an investigation on Russian interference in our elections, two indictments (more coming) and two confessions from a former national security advisor with ties to Russia and Turkey and a drunk, blabbing campaign aid. The stock market looks GREAT, likely artificially propped up by supporters of the president* that want it (and him) to at least look good before the next bottom falls out. 1929...1987...2008...we've been here before. We're hours as of this posting from a government shutdown...a shutdown after a year of "unified republican government." We're now here because of a mythical "wall" that Mexico isn't going to pay for.

One year later, that unified Republican government is on the verge of imploding. Ryan and Senate Majority Leader Mitch McConnell have been unable to pass a regular appropriations bill for 2018, relying instead on a series of continuing resolutions since September to keep the government’s doors open for a few weeks at a time. Now, however, both parties' appetite for these stopgaps has disappeared. Barring a last-minute breakthrough, on Friday at midnight, a government controlled by the same political party will shut itself down for the first time in modern American history. [1]

McClatchy News now reports the FBI is looking into links between the NRA and the Kremlin. [2] From the changing of the Republican platform, the daily violation of the Emoluments Clause; money laundering to his dubious dealings with mobsters and oligarchs, the NRA funneling Russian oligarch rubbles to the Kremlin's preferred candidate and the United States of America is looking a lot more like a criminal enterprise in a Dystopia rather than a federal republic.

The NRA and the KKK have a shared history:

Within months of the surrender at Appomattox, recalcitrant white racists committed to the reestablishment of white supremacy determined to take those guns away from blacks. States in the South passed the Black Codes, which barred the freedmen from possessing guns. Racists quickly learned, however, why gun control is not always as effective as planned: You can draw up any law you like, but people don’t necessarily comply. To enforce these laws, racists began to form posses that would go out at night in large groups, generally wearing disguises, and terrorize black homes, seizing every gun they could find. These groups took different names depending on locale: the Black Cavalry in Alabama, the Knights of the White Camellia in Louisiana, the Knights of the Rising Sun in Texas. In time, they all came to be known by the moniker of one such posse begun in Pulaski, Tennessee after the war: the Ku Klux Klan. [3]

Racism and white supremacy has been our national shame. What we have buried and ignored, others beyond our shores have exploited to their advantage. It is quite American, like Facebook and social media, Putin the puppet master used our divisions to storm the breech of our republic. Apparently, Forbes magazine is a tool of sadism and masochism. The "golfer-in-chief" is going to Mar-a-Largo at a current count of 91 trips as a new Rome burns. The shutdown is looming, "United States" officially is an oxymoron and "they (the Russians) are laughing...at us."

Combing for Earths...

A new type of laser frequency comb (LFC) has been developed by scientists in Europe. The prototype device could lead to improvements in how scientists search for Earth-like exoplanets, measure the expansion of the Universe and test the fundamental constants of nature.

LFCs produce spectral lines of light with evenly spaced frequencies and have a wide range of applications in metrology and spectroscopy. The new LFC was developed by Tobias Herr of the Swiss Centre for Electronics and Microtechnology, Francesco Pepe of the Geneva Observatory and colleagues. It uses a laser-driven microresonator on a silicon-nitride chip that produces 24 GHz pulses for use in calibrating near-infrared spectrometers. This gives it an advantage over traditional LFCs, which operate at frequencies below 10 GHz and create a line spacing that is too small for astronomical spectroscopy.

The pulses are produced by way of a phenomenon known as temporal dissipative Kerr-cavity solitons (DKSs), which involves trapping ultra-short pulses of light in a circular, micron-sized microresonator. Each time the DKS pulse passes the microresonator’s input-output coupler, some of the pulse is siphoned away and directed towards the spectrometer, producing a series of spectral lines that, in the prototype, are each precisely 24 GHz apart. These lines form a spectral comb and act as a precise calibration tool for the spectrometer.

One popular method of detecting exoplanets is the radial velocity technique. This involves measuring a star’s subtle motion that is caused by the gravitational tug of an orbiting planet. These motions are often no faster than walking pace and require highly accurate spectroscopic measurements of the Doppler shift in the star’s light as it moves. The size of the Doppler shift and the period at which it occurs can tell astronomers both the mass and the distance from the star of the planet. The greater the mass of the star, or the less massive or more distant the planet, the smaller the Doppler shift.

BEC in the Blink of an Eye...

Topics: Bose-Einstein Condensate, Modern Physics, Quantum Mechanics

It’s been more than two decades since Carl Wieman and Eric Cornell created the first Bose–Einstein condensate (BEC), confirming the counterintuitive prediction that a macroscopic population of atoms can pile into a single quantum ground state if cooled below some critical temperature. In all those years, the recipe for creating the condensates has hardly changed: Laser Doppler cooling chills the cloud of atoms as close to the critical temperature as possible; when that technique can go no further, evaporative cooling does the rest. But the evaporative cooling step is inefficient. It works by jettisoning most of a cloud’s atoms in order to cool the remaining few—a relatively slow process that can take a minute or more. Now MIT researchers led by Vladan Vuletić have come up with an alternative approach that allows them to create BECs in a fraction of the time.

What gendered arguments are made through this medium? What are the challenges in presenting to black audiences in this largely white genre? How do the creators depict the continent of Africa and/or communities in the African Diaspora? How are black bodies presented in graphic comics and novels? Finally, how are themes of social justice specific to black communities presented in this type of medium?      

This volume would address the above questions in addition to the themes indicated below.

  1. Black Futurism
  2. Black Femininity
  3. Black Masculinity
  4. Imagery of Blackness
