Misbehaving...

Spot the baryon
CERN/LHCb

Topics: Atomic Physics, Large Hadron Collider, Nuclear Physics, Particle Physics

A hint of matter and antimatter behaving differently to each other has been spotted in a new particle for the first time. If the find bears out, it could help explain the existence of all the matter in the universe, and why it was not snuffed out by antimatter long ago.

Physicists think that the big bang should have produced equal amounts of matter and antimatter. But these contrasting particles annihilate each other in a puff of energy whenever they meet, so they should have destroyed each other long ago.

The fact that there is enough matter in the universe today for us to exist and wonder why, means that some mechanism must have favoured matter over antimatter.

“Today we have this complete imbalance between matter and antimatter. We have no evidence of antimatter in the universe,” says Nicola Neri of the National Institute for Nuclear Physics in Milan, Italy. “This is one of the main questions we’d like to answer.”

A 22-year-old college student is leading the new generation of pioneering black women depicted in Hidden Figures. Tiera GuInn is a Rocket and Structural Design and Analysis Engineer working on the space launch system that Boeing is constructing for NASA.



Guinn, who will graduate form MIT with a 5.0 GPA, is designing the “largest and most powerful” rocket in history.

“It’s really humbling,” she told Alabama news station, WBRC . “I design components for the rockets themselves and then I analyze them to make sure they’re structurally sound.”

Guinn was only 6 years old when she began doing math exercises with her mother.



“When we would go to the grocery store she was get me to clip coupons, put it in my coupon organizer, and by the time we’d get to the register I had to calculate the exact total, including tax."

“One day I saw a plane fly by and I just had this realization, ‘I can design planes. I’m going to be an aerospace engineer,’” she continued. “So every middle school class that I chose, it was directed towards that goal. The high school that I chose, that took me an hour to get to everyday, it was because I wanted to be an aerospace engineer.”

Guinn pulls inspiration from Hidden Figures (her favorite movie), and wants to see more diversity her in field.

A book report and cathartic confession on being "invisible."

Last year, I cheered for Cam Newton and the Carolina Panthers because... I grew up in North Carolina, and went to school K-12 and post secondary at North Carolina A&T. How could I NOT cheer for the Panthers?

I am now post another Super Bowl, this one I didn't watch. I considered the Patriots winning a foregone conclusion, and the choke by the Falcons was probably disappointing to classmates that now live in the ATL.

This Bowl is post a very divisive election season that gave us a divisive Chief Executive. His friendship with the owner, the coach and the quarterback only politicized it more than necessary. I watched the original Star Trek episodes on BBC America and checked in on Facebook. I'm disappointed, but not as emotional as last year.

Ralph Ellison does an excellent job of painting a picture of the times through the patronage of public HBCUs by dominant financiers and the political aspects of "The Brotherhood," that I thought was an inference to Red Scare Communism that inspired the government to spy on its own citizens through COINTELPRO. We've obviously recently locked arms with the Kremlin, though such fears still seem extended to brown people.

However, I must go to a "team-building" lunch today, post this game I did not see, for the reason I will publish as having "no dogs in the hunt." It will be true, and hopefully pivot conversations from politics to just work-related issues.

A way of using a superpower of my swagger: invisibility.

Amazon: Invisible Man is a milestone in American literature, a book that has continued to engage readers since its appearance in 1952. A first novel by an unknown writer, it remained on the bestseller list for sixteen weeks, won the National Book Award for fiction, and established Ralph Ellison as one of the key writers of the century. The nameless narrator of the novel describes growing up in a black community in the South, attending a Negro college from which he is expelled, moving to New York and becoming the chief spokesman of the Harlem branch of "the Brotherhood", and retreating amid violence and confusion to the basement lair of the Invisible Man he imagines himself to be. The book is a passionate and witty tour de force of style, strongly influenced by T.S. Eliot's The Waste Land, Joyce, and Dostoevsky.

Amazon.com Review

We rely, in this world, on the visual aspects of humanity as a means of learning who we are. This, Ralph Ellison argues convincingly, is a dangerous habit. A classic from the moment it first appeared in 1952, Invisible Man chronicles the travels of its narrator, a young, nameless black man, as he moves through the hellish levels of American intolerance and cultural blindness. Searching for a context in which to know himself, he exists in a very peculiar state. "I am an invisible man," he says in his prologue. "When they approach me they see only my surroundings, themselves, or figments of their imagination--indeed, everything and anything except me." But this is hard-won self-knowledge, earned over the course of many years.

As the book gets started, the narrator is expelled from his Southern Negro college for inadvertently showing a white trustee the reality of black life in the south, including an incestuous farmer and a rural whorehouse. The college director chastises him: "Why, the dumbest black bastard in the cotton patch knows that the only way to please a white man is to tell him a lie! What kind of an education are you getting around here?" Mystified, the narrator moves north to New York City, where the truth, at least as he perceives it, is dealt another blow when he learns that his former headmaster's recommendation letters are, in fact, letters of condemnation.

What ensues is a search for what truth actually is, which proves to be supremely elusive. The narrator becomes a spokesman for a mixed-race band of social activists called "The Brotherhood" and believes he is fighting for equality. Once again, he realizes he's been duped into believing what he thought was the truth, when in fact it is only another variation. Of the Brothers, he eventually discerns: "They were blind, bat blind, moving only by the echoed sounds of their voices. And because they were blind they would destroy themselves.... Here I thought they accepted me because they felt that color made no difference, when in reality it made no difference because they didn't see either color or men."

Invisible Man is certainly a book about race in America, and sadly enough, few of the problems it chronicles have disappeared even now. But Ellison's first novel transcends such a narrow definition. It's also a book about the human race stumbling down the path to identity, challenged and successful to varying degrees. None of us can ever be sure of the truth beyond ourselves, and possibly not even there. The world is a tricky place, and no one knows this better than the invisible man, who leaves us with these chilling, provocative words: "And it is this which frightens me: Who knows but that, on the lower frequencies, I speak for you?" --Melanie Rehak

How Should a Beginner go About Networking?

So, I am a very green SFF writer in a city--Memphis--that is not very nurturing to my genre. This is due to the fact that there is not a significant amount of established writers here.

Here is what I want to know:

1) How crucial are writing groups to local networking? There are no well-known groups here, so I may have to create my own if need be.

2) What should I seek to accomplish in networking with people in the SFF industry?

3) How crucial are Sci Fi-centered conventions to networking and selling books?

Thanks!

Higher education administrators, students and industry professionals gathered in Washington, D.C., to speak to Congressional staffers and representatives about the need to attract more African-American men to STEM. COURTESY GEORGIA INSTITUTE OF TECHNOLOGY


Topics: African Americans, Diaspora, Diversity in Science, STEM, Women in Science


I recall once this observation being made by a new hire (at the time) rotational engineer and fellow Aggie I worked with at Motorola:

Him: "Reg!"

Me: "What?"

Him: "We were the 'only black engineers' in that room," my fellow alumni said.

Me: "And, we were and are the best damn engineers IN that room, or any other!" I shot back. "Do you have a problem with that?"

He gave me a grin and an "Aggie Pride" verbal acknowledgement. I reassured his swagger... his end-of-rotation presentation blew them away. I beamed with pride.

Black men are faulted for swagger, even President Obama received grief for it, although I think it largely pivoted on the southern racial parlance of "being uppity." Urban Dictionary defines swagger as: "How one presents him or her self to the world. Swagger is shown from how the person handles a situation. It can also be shown in the person's walk."

The interaction my younger alumni and I had happened and likely happens quite often. You have to learn the rules of the road rather quickly. Sometimes going to church, or a frat meeting, or a concert, or simply chatting on the phone with a close friend is how you de-stress; unwind.

More often than not, as Paul Lawrence Dunbar eloquently stated (and Dr. Maya Angelou gave her stupendous interpretation) it is a mask. It hides rage and disappointment at ignorant comments made around you, daring you to respond to a shout of "Black Lives Matter," when the discussion - about, you know, work - didn't even CENTER around that (this happened last year, 2016 during the divisive election cycle). When I challenged the individual by simply asking "what did you mean by that?", he slinked away like an Internet troll nervously and quickly changing the subject; suddenly remembering Human Resources exists for a reason. The struggle is no different in complexion or complexity in graduate school, as you are usually "the one," so you better be supremely confident in yourself or convince others you are until you are. Walk with confidence until you're sure you've mastered your situation, putting in the hard work until you do. Don't "fake it till you make it": make it!

Swagger... It covers a multitude of sins that could be committed when you're not in control of your emotions. Thankfully, I have access to a 300 pound heavy bag at my community's gym that takes the abuse instead! At least 37 years of martial arts training and channeled anger keeps me in reasonably good shape.

Swagger... Never let 'em see you sweat unless they see you in the gym!

It's not often that you hear calls for more men to participate in science, technology, engineering and math fields.

Advocates consistently beat the drum to find ways to engage more female and minority students in STEM fields, which are still largely dominated by men. But within that group is perhaps one of the most underrepresented demographics: African-American men.

Among U.S. citizens and permanent residents, the number of black men who earn science and engineering doctorates grew by more than 25 percent in 10 years, according to data from the National Science Foundation. While that appears to be a large growth, the absolute numbers barely budged between 2003 and 2013 – inching up from just 631 of 13,921 recipients to 798 of 16,542 recipients – and the representation has stayed essentially flat, between 4.5 percent and 4.8 percent of all science and engineering doctorates. The number of science and engineering bachelor's degrees awarded to black men increased 45 percent, from 12,484 in 2002 to 18,102 in 2012. But similarly, black men as a proportion of all science and engineering bachelor's degree recipients has remained essentially unchanged, at 6.1 percent in 2002 and 6.2 percent in 2012.

Like women and other minority groups, African-American men are also underrepresented in the workforce. Census data show that in 2010, African-American men made up 6.2 percent of the population between 18 and 64 years old. But in the same year, the NSF reported that black men represented just 3 percent of scientists and engineers working in those fields.

Earth in Human Hands...

Image Source: Amazon link


Topics: Climate Change, Global Warming, Greenhouse Gases


Amazon: For the first time in Earth's history, our planet is experiencing a confluence of rapidly accelerating changes prompted by one species: humans. Climate change is only the most visible of the modifications we've made--up until this point, inadvertently--to the planet. And our current behavior threatens not only our own future but that of countless other creatures. By comparing Earth's story to those of other planets, astrobiologist David Grinspoon shows what a strange and novel development it is for a species to evolve to build machines, and ultimately, global societies with world-shaping influence.

Without minimizing the challenges of the next century, Grinspoon suggests that our present moment is not only one of peril, but also great potential, especially when viewed from a 10,000-year perspective. Our species has surmounted the threat of extinction before, thanks to our innate ingenuity and ability to adapt, and there's every reason to believe we can do so again.

Our challenge now is to awaken to our role as a force of planetary change, and to grow into this task. We must become graceful planetary engineers, conscious shapers of our environment and caretakers of Earth's biosphere. This is a perspective that begs us to ask not just what future do we want to avoid, but what do we seek to build? What kind of world do we want? Are humans the worst thing or the best thing to ever happen to our planet? Today we stand at a pivotal juncture, and the answer will depend on the choices we make.

filling my sketchbook

What am I up too....besides working at a grocer, filling another sketchbook. Been hooked on combining quonset huts with shipping containers. Living in big boxes will drive ya nuts so I added quonset huts to get an arched ceiling. Also wondering if all steel structures are a good thing. Plywood and foam sandwich panels, wood post and beam and adobe are much better materials organically, psychologically and economically. I also think about having curved walls so that rooms are not square, art that is not square. I can't imagine too much technology in a personal space. Something about interaction on a base level vs time saving devices. They only save time if you are in a hurry to go to work for someone else. Personal elevators, how ever they function, are very cool. How do you build a place for less stress and distractions. One reason we are not more developed than we are is the intrusive media. We get flooded with ideas and speakings of all kinds, good, bad and real ugly. We need a filter and a flow rate control and an off switch. Personal, it is all personal now yet some of our biggest arguments are when we must choose a social distinction, philosophical, religious, historical label, genetic source vs the government legal code designation. The kool thing is that we can design a concept and live it and if you can train your children in this way.........utopia or the nut house is yours.

The STEM (Science, Technology, Engineering, and Mathematics) fields are boom town for jobs in today and tomorrow’s economy. According to Change the Equation, from 2014 to 2024, jobs in computing are slated to increase 19%, in advanced manufacturing 16%, and in engineering 12%. According to the Bureau of Labor Statistics, from 2012-2022, there is going to be a 37% increase in information security analysts (no surprise there!), a 27% increase in operations research analysts, a 27% increase in statisticians, and a 27% increase in biomedical engineers. This is doubly impressive, because the median salary in 2013 for all of these jobs was over $79,000 per year. *
Confession of a STEM survivor
Summarizing previous posts on this subject:
Women and minorities are not only underrepresented in the sciences, they are openly discouraged from pursuing STEM careers at the university level and at early life stages. I was personally insulted by my middle school science teacher - "No, you big dummy!" - after asking a question about calculating the coefficient of linear expansion on a metal wire. I had stifled the immediate urgent need at that moment to deck him, confident of the outcome with the authorities if I had. My parents were not amused, and scheduled a visit with the principal. That was followed by a sweaty, self-preserving "apology" from the science teacher. I passed his class with a descent grade, and moved on from the twerp. The fact both groups are so low means discouragement is remarkably efficient to maintain the status quo of the "usual suspects" in the sciences, and a concentration of wealth and opportunities along gender and cultural lines. Suffice to say, to resist the "haters": you have to want it!
Albert Einstein was so fond of answering the fan mail of children interested in science, author Alice Calaprice wrote a book on it. In an exchange with a young science fan from South Africa named Tiffany:
September 19, 1946: "I forgot to tell you, in my last letter, that I was a girl. I mean I am a girl. I have always regretted this a great deal, but by now I have become more or less resigned to the fact. Anyway, I hate dresses and dances and all the kind of rot girls usually like. I much prefer horses and riding. Long ago, before I wanted to become a scientist, I wanted to b e a jockey and ride horses in races. But that was ages ago, now. I hope you will not think any the less of me for being a girl!"
To which, Einstein's reply was classic, and classy (circa October 1946):
"I do not mind that you are a girl, but the main thing is that you yourself do not mind. There is no reason for it."
The face above is cherub and innocent. The discouragement from "powers-that-be" will be formidable, but not insurmountable. I tutor and volunteer as much as time allows outside of my work hours to help, encourage and most importantly: be SEEN.
I am a member of Kappa Alpha Phi Fraternity, Inc. a part of a list of African American Sororities and Fraternities collectively known as The Divine Nine. Part of our mandate within our respective organizations and communities is just what I've described as well as fundraising for scholarships to help such students as the one pictured above.
You don't have to be a member of any Greek Letter organization, as some cannot due to not attending or finishing a four-year college. My father's motivation on my first day of college was a simple statement: "Before I die, I want you to be able to take care of yourself." My father formally had a sixth-grade education. After serving in the US Navy during World War II, he took and passed a college entrance exam, but chose not to attend. My mother had an Associates in Practical Nursing. Her encouragement was always: "You can do ANYTHING you want to do, if you put your MIND to it and believe you can do it!" Mildred and Robert are both deceased. Their son (me) completed a degree in Engineering Physics at North Carolina A&T State University; a Graduate Certificate in Microelectronics and Photonics at Stevens Institute of Technology and has applied to the School of Nanoscience and Nanoengineering. Their grandsons attended college (my oldest in Real Estate); my youngest will receive his degree in Civil Engineering May 2017. Sometimes, all you need to be is a teacher, friend, sister, brother, cousin, aunt, uncle or parent with an encouraging word or two.
What's important in the long run is not being hidden, but encouraging and available. The return can literally be generational.

Shyrmions...

Topics: Electronics, Neuromorphic Devices, Particle Physics, Spintronics


Simulations suggest that magnetic skyrmions could form the basis of ultra-low-power-consumption devices that mimic the memory and learning functions of neural synapses.

Despite advances in computer power, there are still tasks that are best done by biological brains. Efforts to emulate the way the brain is wired have led to work on "artificial synapses" as connections for use in "neuromorphic" computers that try to emulate the functionality of a biological brain. Researchers in China have now demonstrated that the skyrmion – a type of magnetic quasiparticle – could be used to create energy-efficient synaptic devices.

New challenges are not always best met with old tools, and as challenges go, emulating synaptic connections in a scalable system – the human brain contains hundreds of trillions of synapses – is no mean feat. Synapses do more than connect neurons, they weigh how well neurons are connected through signal spiking and modulation processes that are thought to be the basis of human learning and cognition. While some progress in the development of synaptic devices has been made using phase-change memories, Ag-Si memories and resistive memories, studies of magnetic skyrmions suggest they may be a promising alternative.

Skyrmions are particle-like regions within a field where all of the field vectors point either towards or away from a single point in space. They were originally proposed in the 1950s by British physicist Tony Skyrme to explain aspects of particle physics. Researchers have since discovered that some collective excitations of electron spins in solids behave much like skyrmions, and the first observation of a magnetic skyrmion lattice was reported in 2009. These solid-state skyrmions could be potentially useful in next-generation electronics and spintronics.

Okay, I lied.

I lied when I said I wasn't going to talk anymore about Hidden Figures. I obviously featured it on #P4TC and that AFTER I bought the book the movie was based on. Congrats to the cast for the Screen Actor's Guild Award for best cast (Denzel Washington and Viola Davis won Best Actor and Best Supporting Actress respectively).

I also lied that I wouldn't do special months again. It's usually a double post of science papers that I've read and a post for the respective history month: I've done posts for African American History Month; Women's History Month and Hispanic Heritage Month. It's enjoyable, but exhausting as a lot of thought goes into the posts so as to not repeat themes/stories/history.

However, lies ("alternative facts") are fast becoming truth and verifiable, factual truth lies. A Federal Republic: "is a type of government made up of smaller areas such as states or provinces where the central government cedes certain powers to the individual areas for self-government purposes. The citizens of the federal republic elect their own representatives to lead them," [1] and only functions well when reality can be judged and fairly reported on by its leadership to the governed.

Even before "alternative facts" recently entered our lexicon, some disturbing tendencies have already been documented:

The Civil War "wasn't about slavery, but about state's rights," a canard continually debunked, but apparently taught in public schools still.

- In Texas, slaves were referred to as "workers," hinting at volition instead of what can properly be termed as a kidnapping. A concerned mother pointed that out in 2015.

- The aforementioned Hidden Figures.

- When you think African American, Black, Negro, what's the first thing that comes to mind: scientists, engineers, or athletes and thugs? Transmitted images, shape narrative and matter in how we interact with one another individually and as a republic.

Truth, and our own thoughts are going to be precious things in days to come. They always have been, and why power tends to spend inordinate money and time to shape narratives of cultures in particular and civilization in general. It is why Dr. Woodson created Negro History Week (as it was originally know) which has evolved into African American History Month. It is not just the Negro mis-educated, but a sizable number within the American electorate that still believe social myths of innate superiority; a faux hierarchy that can only be attributed to racism, pseudoscience and magical thinking. [2]

Our society has always been herded by the powerful through the control of information, from print media to radio; radio to television and now Net Neutrality threatens to alter the Internet commons into a "Ministry of Truth," [3, 4] accessible only on a tiered payment system, bringing back the "information superhighway debates" of the nineties.

Affirming our humanity, truth: precious, manipulable and fleeting is the last real commodity we all have. What will be presented this February roaring like a lion, will be our collective Hidden History; it will be the TRUTH.

If you make a man feel that he is inferior, you do not have to compel him to accept an inferior status, for he will seek it himself. If you make a man think that he is justly an outcast, you do not have to order him to the back door. He will go without being told; and if there is no back door, his very nature will demand one."

Red Nova...

Topics: Astronomy, Astrophysics, Cosmology

It's only five years away...

In 2022, there will be a spectacular sky show. Two stars will merge into one, pushing out excess gas into an explosion known as a red nova. At magnitude 2, it will be as bright as Polaris in the sky, and just behind Sirius and Vega in brightness. The collision in the constellation of Cygnus will be visible for up to six months.

That’s pretty impressive. What’s more impressive: we’ve never been able to predict a nova before. But Lawrence Molnar, a professor of astronomy and physics at Calvin College, was able to find a pair of oddly behaving stars giving an indication of what might happen.

The objects, termed KIC 9832227, are currently contact binaries. Contact binary refers to two objects that are so close they are currently touching. The object was discovered by Kepler. The expected outcome is a merger between the two stars that will put on quite a show. Because both are low mass stars, the expected temperature is low, with Molnar terming it a “red nova.”

Musing Hydrogen...

Harvard physicists say they photographed hydrogen in three different forms, from left to right: transparent hydrogen, black hydrogen, and finally, shiny metallic hydrogen. (R. Dias and I.F. Silvera) Source: Forbes.com

Topics: Condensed Matter Physics, Materials Science, Research, Theoretical Physics

Disclaimer: I was just as initially psyched by the reports of Metallic Hydrogen at Harvard. It's been theoretical since I was an undergrad (and that was a long time ago). Then, I remembered all the hype over cold fusion and calmed down. The key to my skepticism is repetition: another lab (several, in fact) will have to repeat the experiment to within an acceptable degree of error to one another. It will have to face grueling peer review that won't be kind, or for the squeamish. It's through this process we can distinguish science from malarkey.



Two physicists say that they have crushed hydrogen under such immense pressures that the gas became a shiny metal — a feat that physicists have been trying to accomplish for more than 80 years.

But other researchers have serious doubts about the claim, the latest in a field with a long history of failed attempts.

Ranga Dias and Isaac Silvera, both physicists at Harvard University in Cambridge, Massachusetts, first posted a report of their results on the arXiv preprint server last October [1], which attracted immediate criticism. A peer-reviewed version of the report was published on 26 January in Science [2], but sceptics say that it includes little new information.

Five experts told Nature’s news team that they do not yet believe the claim, and need more evidence. “I don’t think the paper is convincing at all,” says Paul Loubeyre, a physicist at France’s Atomic Energy Commission in Bruyères-le-Châtel.

Silvera and Dias say that they wanted to publish their first observation before making further tests on their fragile material.

70 years...1947 to 2017.

Clearly in my fifth decade of life, I have vivid disturbing memories of the world post Hiroshima and Nagasaki, 1945:

"Duck and cover drills": the most asinine exercise to bend-over-and-kiss-your-ass-goodbye I recall with a certain level of disdain.

The Red Scare: Post the McCarthy era, ALL things Russian were bad. COINTELPRO used the scare as raison d'être to infiltrate Civil Rights organizations like the Black Panther Party of Self Defense, the Congress Of Racial Equality (C.O.R.E.), the NAACP, the Nation of Islam, the Southern Christian Leadership Conference; the Student Nonviolent Coordination Committee (S.N.C.C.). We lived through The Cold War, the possibility of a conflict with Gog and Magog loomed in every ROTC and Sunday School class. Hal Lindsey's The Late, Great Planet Earth practically dripped with it.

M.A.D.: Mutual (or Mutually) Assured Destruction. When you've each reduced the planet to a crisp cinder, what victory does ANYONE left alive sanely claim?

The Doomsday Clock was meant to be figurative only. The Bulletin of Atomic Scientists have always used it to foster a continual public debate (when you debate, you cannot war) regarding the existentialism question Shakespeare through Hamlet posed:

To be, or not to be--that is the question:

Whether 'tis nobler in the mind to suffer

The slings and arrows of outrageous fortune

Or to take arms against a sea of troubles

And by opposing end them. To die, to sleep--

No more--and by a sleep to say we end

The heartache, and the thousand natural shocks

That flesh is heir to. 'Tis a consummation

Devoutly to be wished. To die, to sleep--

To sleep--perchance to dream: ay, there's the rub,

For in that sleep of death what dreams may come

When we have shuffled off this mortal coil,

Must give us pause. There's the respect

That makes calamity of so long life.

For who would bear the whips and scorns of time,

Th' oppressor's wrong, the proud man's contumely

The pangs of despised love, the law's delay,

The insolence of office, and the spurns

That patient merit of th' unworthy takes,

When he himself might his quietus make

With a bare bodkin? Who would fardels bear,

To grunt and sweat under a weary life,

But that the dread of something after death,

The undiscovered country, from whose bourn

No traveller returns, puzzles the will,

And makes us rather bear those ills we have

Than fly to others that we know not of?

Thus conscience does make cowards of us all,

And thus the native hue of resolution

Is sicklied o'er with the pale cast of thought,

And enterprise of great pitch and moment

With this regard their currents turn awry

And lose the name of action. -- Soft you now,

The fair Ophelia! -- Nymph, in thy orisons

Be all my sins remembered.

At least...it USED TO BE figurative, only.

A Need For Starships...

Popular Mechanics (Discovery 1: 2001 - A Space Odyssey): What Would a Starship Actually Look Like?

Topics: NASA, Politics, Space Exploration, Star Trek

Star Trek was born in the 1960's during counter-culture demonstrations against the Vietnam War; for the Civil Rights Act (1964), Voting Rights Act (1965) and Fair Housing Act (1968). It was a decade of assassinations: Medgar Evers, Malcolm X, Martin Luther King and Robert F. Kennedy. It was an admittedly Pollyannaish futurism with fantastic technologies beyond the capabilities of our physics likely now and in the near future. From my perspective as an African American and a budding science nerd, it was a hope beyond the fear of nations annihilating each other, and that we'd stop fretting like paranoid, prehistoric Neanderthals over the magical powers of Melanin.

A recurring theme from old to new Trek is Native Americans. In Kirk's timeline, they were excavated from Earth by the aliens called the Preservers, resulting in temporary amnesia for James T and a stoned (the rocks kind) pregnant wife.

In the Next Generation, Picard met a tribe that left Terra on their own in the 22nd Century, using the fantastically impossible warp drive because we hadn't gotten to the Utopia of a United Federation of Planets. Ironically, they were again being asked to move, this time from a contested colonial planet between Federation and Cardassians.

Chakotay is described as a starfleet tactical officer, Maquis terrorist and Native American descendant: A renaissance man of sorts in the 24th Century. The Next Gen tie-in was his father died defending their home world on the same Cardassian outpost. As with a lot of Trek stories, his father would talk to him on vision quests in his often expressed Mayan spiritual traditions (i.e. no one ever really dies).

Boomers in the 22nd Century were people that lived most of their lives in space, many of them people of color as evidenced by Ensign Travis Mayweather.

Lastly, in the novel Federation, Zephram Cochrane‎ apparently released the plans for warp drive on the Internet: for the low price of $50,000 (which I assume covers radiation shielding) you too would go faster-than-light to (presciently) Alpha Centauri.

The Venn Diagram of the three previous examples I've given is a suggested departure, an Exodus from Mother Earth to a kind of Elysium without dying. The former Native Americans carried with them their culture and traditions as I'm sure Mayweather and his family carried theirs. Perhaps Roddenberry and subsequent writers were suggesting a social pressure for Earthlings to finally listen to their better angels, kind of a societal potty-training (embarrassment can be an effective motivator).

It occurred to me: what if we COULD voluntarily leave? At one-tenth the speed of light (0.10 c) would involve time dilation, so for every year on your starship several years (if not decades or centuries, depending on the destination) would pass on Earth. Whatever problems you experienced with say, discrimination and xenophobia (traffic tickets, or worse) would be consumed by considerable distance and time. What would be the reaction of "powers that be?" A backlash, perhaps? "Legal" blocks put in to keep humans planet-bound, preventing pilgrims to the stars on an "over-ground railroad?" It's hard to reinforce a hierarchical society of implicit bias and income inequality when The Untouchables (traditional and figurative) decide to leave the planetary caste system.

We are bound by our own terrestrial limits and tribal prejudices. We are stymied by our fears of the unknown; of "the other"; of facts that don't comport to our preconceived notions and beliefs. Lacking critical thinking and reasoning skills, we violently fight the unknown, the only outcome being the eventual destruction of that which is feared, or self-destruction by one's own fears.

Spaceflight is not trivial: radiation (as I've mentioned), lack of gravity causing muscle deterioration and mineral loss from bones; long-term weightlessness seems to result in nearsightedness in astronauts on the ISS. Not to mention: food, and bathrooms (delicately, someone's going to have to figure out how to have sex in less than 1 g). Near-miraculous technologies like 0.10 c propulsive acceleration, rotating habitats to simulate gravity and adequate radiation shielding have yet to be created. Such design breakthroughs require an environment a little less hostile to science and facts as I'm currently observing in the US.

The need for the overview effect on an extensive, massive scale, seeing ourselves teamed to survive even as close as Mars, or mining the asteroid belts. Space programs such as that of a starship or interplanetary engines requires cooperation across borders and economies; across cultures and religious differences. It's hard to war with the other when the same shared goal is surviving to the next day.

Currently, homophobia, racism, sexism, xenophobia (translate: fear, the bedrock of hierarchical, caste-based societies) and consumer driven, cronyism-rewarding technology is threatening the continued existence of the species.

A visible hope: I had meant to complete "Invisible Man" by Ralph Ellison last Friday during my fast from the inaugural festivities. My small stance seemed to have contributed an effect.

At a local restaurant, I was reading the book waiting for my meal in front of a gas-powered fireplace, decorated with the head of a buck, the portrait of a couple (likely, the owner-founders); a fireman's cap, a safety cap, waffle iron and snow shoes.

A gentleman was sitting with who appeared to me his father and son, three generations enjoying a late breakfast at Cracker Barrel. He noticed my book and it sparked a conversation: I found out he had read the book, loaned to him by his best friend. He raved about it, describing details from the first part of it only someone who had read it would know (specifically, New York fight clubs). At his friend's untimely death at 26, he found a photo of he and his friend in Prague inside the pages. He described his cherub, blonde son as a "miracle baby": he and his wife had tried to adopt 3 times unsuccessfully. His wife was finally pregnant, long enough for his mother to see his son's "bump." She died two months before he was born. I told him how old my adult sons were and to enjoy his. All this from a book I neglected to finish last week. I'm glad I didn't and appreciative of the human connection it fostered. I plan to complete it this week. The hard copy of "1984" is currently out-of-stock on Amazon. As apropos as it is, I recommend this and other classics as we grope through this current darkness.

Earth and Vulcan apparently survived their fictional world wars and flights of emotion and irrationality that led to them. An initial Exodus (Earthlings to Centauri; Vulcans to Romulus) pushed their fictional societies towards an overview enlightenment.

But things only happen perfectly in Star Trek, such that life may NOT imitate art.

Flexible Ferroelectrics...

Until recently, “flexible ferroelectrics” could have been thought of as the same type of oxymoronic phrase. However, thanks to a new discovery by the U.S. Department of Energy’s (DOE) Argonne National Laboratory in collaboration with researchers at Northwestern University, scientists have pioneered a new class of materials with advanced functionalities that moves the idea from the realm of irony into reality.

Ferroelectrics are a useful type of material that is found in capacitors that are used in sensors, as well as computer memory and RFID cards. Their special properties originate from the fact that they contain charged regions polarized in a specific orientation, which can be controlled with an external electric field. But they’ve also had a big drawback as engineers try to use them in new inventions.

“Ferroelectric materials are known for being quite brittle, and so it has always been a big challenge to make them mechanically flexible,” said Argonne nanoscientist Seungbum Hong, who helped to lead the research. “Because ferroelectricity and this kind of flexibility are relatively rare properties to see on their own, to have both ferroelectricity and flexibility in this new material is basically unprecedented.”

The optical properties of single-walled carbon nanotubes (SWCNTs) change when the tiny structures are filled with water. That is the conclusion of scientists in Belgium and the US, who attribute the change to a "quasi-phase transition" that occurs in the water – although the exact nature of the transition is unknown. The research points to a new technique for studying confined water molecules – which is crucial to various branches of science, but it is surprisingly difficult to do. The study could lead to better ways of delivering drugs in the body and even boost our understanding of quantum mechanics.

SWCNTs are hollow hair-like structures with walls that are one atom thick. Normally they are closed at both ends, but sometimes the ends can be open and Sofie Cambré of the University of Antwerp in Belgium and colleagues have previously shown that open SWCNTs rapidly fill with other molecules and hold on to them. Why this occurs is not well understood, but Cambré says "it seems the energy of a molecule inside a SWCNTs is much lower than when you have them separated."

SWCNTs are naturally fluorescent, and the colour of the fluorescent light shifts if the nanotube is filled. "You need dedicated equipment to really see these very small shifts", Cambré says. However, by measuring the shifts, researchers can potentially gain useful insights into the behaviour of confined molecules.

Recipe For Time Crystals...

Figure 1: Yao et al. [7] have developed a blueprint for creating a time crystal and a method for detecting it, which has been followed by two experimental groups [8, 9]. Quantum spins are subjected to imperfect spin-flip driving pulses and then allowed to interact with each other in the presence of strong random disorder in the local magnetic fields. The sequence repeats after a total time period T, but the spin system exhibits emergent oscillations with period 2T—the hallmark of a discrete quantum time crystal.

A detailed theoretical recipe for making time crystals has been unveiled and swiftly implemented by two groups using vastly different experimental systems.

The story of time crystals—whose lowest-energy configurations are periodic in time rather than space—epitomizes the creative ideas, controversy, and vigorous discussion that lie at the core of the scientific process. Originally theorized by Frank Wilczek in 2012 [1] (see 15 October 2012 Viewpoint), time crystals were met with widespread attention, but also a healthy dose of skepticism [2]. This ignited a debate in the literature, culminating in a proof that time crystals cannot exist in thermal equilibrium, as originally imagined by Wilczek [3]. But the tale did not end there. It was later argued that time crystals might still be possible in periodically driven systems, which can never reach thermal equilibrium [4–6]. Three recent papers have now completed the story, one proposing a roadmap for creating a nonequilibrium time crystal in the lab [7], and two describing subsequent experimental demonstrations in systems of trapped ions [8] and spin impurities in diamond [9] (both posted on the physics arXiv preprint server).

Empty space exhibits continuous translation symmetry: nothing distinguishes one point from any other. Yet ordinary crystals break this symmetry because atoms are periodically arranged in specific locations and display long-range spatial correlations. Given that we live in four-dimensional spacetime, it is natural to wonder if an analogous process of crystallization and symmetry breaking can arise along the time dimension as well [1]. If it does, then any such time crystal should return back to its initial state at specific times, while spontaneously locking to an oscillation period that differs from that of any external time-dependent forces. Hence this definition excludes all known classical oscillatory systems such as waves or driven pendulums.

To Pluto and beyond!
Nearly two years after its historic encounter with the dwarf planet Pluto, NASA's New Horizons spacecraft is getting ready for its next big adventure in the icy outskirts of the solar system.
Now, the spacecraft is on its way to a small, ancient object located about 1 billion miles (1.6 billion kilometers) beyond Pluto in the Kuiper Belt. This distant region surrounds the solar system and is filled with trillions of icy rocks that have yet to be explored. The new target was discovered by the Hubble Space Telescope in June 2014, and it was dubbed 2014 MU69.
A world of discoveries
It took the spacecraft about 16 months to beam back all of its data from the Pluto flyby, and planetary scientists have had a ball with that data.
"The New Horizons flyby of the Pluto system was completely successful, and now we've got all the data on the ground and we're putting a bow around it," Alan Stern, the New Horizons principal investigator at Southwest Research Institute, said in a Facebook Live event on Thursday (Jan. 19).
Thanks to New Horizons, scientists now have a global map of Pluto and the most detailed images yet of the dwarf planet's bizarre, mountainous landscape and icy volcanoes. Tall mountain ranges seen on Pluto also suggest recent geological activity on the dwarf planet's surface.
