Terrence adult league hockey 10-28-2012Alicia kindly asked me to come and talk about my website, Alien Star Books, how it all came about, and what I’m doing with my vast proceeds of 54 cents for the past year. (Ummm, nothing, they don’t pay out until you’ve reached $10!)

 

Let me start at the beginning. A little over a year ago, my son needed a book to read for his English class. He’s a hockey player, not a reader, so he really doesn’t have any books that he’ll willingly read. He hates reading. Painful to me as a writer, yes, but I can’t cram the books down his throat, so I keep coughing up the cash for hockey.

Anyway, I found him perusing my bookcases looking for a book. I suggested several and he said no, no and no yet again. Finally, after I told him that the main character in Robert Heinlein’s book “Tunnel in the Sky” was Black, but you have to figure it out for yourself, he gave a heavy sigh and said he’d take that one.

I was excited! Having found something, anything, that the boy would read, I started a search for age appropriate science fiction and fantasy books that featured main characters of Color.

That was when I slammed into the brick wall. The classic stereotypical White male hero -- think John Carter of Mars -- is alive and well in my favorite genres.

Where are the swashbuckling, action-adventure, space opera heroes? Alas, they’re awash in a sea of White testosterone. Oh, there’s a sidekick here and there and the occasional exotic female alien, but sci-fi is filled with stereotypical “White guy saves the universe” tales. Fantasy, while it does incorporate non-human heroes, including elves, is all too often based in the mythology of one tiny island off the coast of England. There’s nothing wrong with Irish legends and the Fae, but dang, there’s a whole world out there! Why are 99 percent of fantasy stories based on Irish mythology? There’s nothing wrong with featuring red-headed, green-eyed, magic-wielding men and women, but where are the People of Color? Where are the magical tales of Egypt and Africa and Asia and the Americas? Where are my ancestors, my mythologies, my heritage? Where does my son’s mixed heritage fit in?

How is this boy of mine, a child of the new century, a young man of Black/Mexican/Italian/Welsh/Cherokee/White/mixed heritage supposed to relate to a constant parade of White-makes-Right heroes of the future? The answer is: he can’t. He can’t relate to John Carter because no matter how fair his skin, no matter how mixed his heritage is, when he steps outside the door of his home and into the view of strangers, he’s a 6 foot tall Black man. Dark, medium, light, so bright he’s darn near White, it doesn’t matter -- he’s still Black.

As I wrote in one of my blogs a while back, there is a deep scar, a chasm across the consciousness of this country. The deeply held pain of the Trail of Tears, the many trails of tears, manifest destiny, slavery and the Civil War, the Chinese Exclusion Act of 1880, the Mexican Repatriation of the 30s, the Japanese internment and so many more acts against People of Color, lead directly to the policies of exclusion that affect the United States to this very day. Racism hasn’t gone away. It’s still here, just clothed in a suit and tie and smiling mask that hides that bitter truth.

Still, just because the ugly past has shaped our nation and our peoples in so many ways, and few of them good, we don’t have to be held to that path forever. We can move past it and into a better future that includes all of my Brothers and Sisters of Color.

We have to live in the present, but our imaginations can soar to a new level of understanding. We can look forward, even as the ground-breaking TV show Star Trek looked forward, and give our kids a dream of a different future, where the color of a man or woman’s skin is not the defining factor in their lives. Where a young man can guide a spaceship to Mars or where a woman can lead a rebellion against alien oppressors and his/her Color is just a part of who he/she is, accepted and cherished as a part of a unique Terran or Martian or far future culture. A future where our skills and talents are the most important factors in our lives -- not the color of our skin, the texture of our hair, our Faith or the birthplace of our forefathers.

Thus Alien Star Books was born. I am determined to find books that feature protagonists that my son can relate to while he enjoys good stories and shares my own vision of a diverse future. This website is a labor of love, to help not only my own child, but also the teens, young adults and their parents, guardians, caregivers and teachers find good books with main characters of Color that can inspire our children to reach for the stars.

It’s a continuing process, to find new as well as classic books that will inspire our kids to read and look past the ugly realities of the present and into a new and exciting future, full of possibilities. Science fiction, fantasy, urban fantasy, paranormal romance, steamfunk -- all fill a void in our kids’ lives. There is a whole universe out there, ready for our youth of all races, colors, ethnicities, creeds, sexualities, human, non-human and alien to reach out and claim the future as their own.

Please feel free to come by, check out the titles and send me great suggestions. I’m always open to a referral, a review or a fabulous new author. And remember, Alien Star Books is all about INCLUSION, not EXCLUSION, so there is a place for everyone.

Well, OK, maybe not KKK members, neo-Nazis, racists, terrorists or other “not nice” people -- unless they’re the bad guys. LOL!

Positive Possibilities...


The irony is this post appears on the traditional "April Fool's Day." This however, is not a joke.

The following is a quote I read in the book "Fool Me Twice: Fighting the Assault on Science in America," by Shawn Lawrence Otto. After reading the indictment of Galileo for "proposing the sun was the center of the world [and the earth was not]," this hit me like a thunderbolt:

"...Science is a reliable method for creating knowledge, and thus power...science constantly disrupts hierarchical power structures and vested interests in a long drive [my add: by science] to give knowledge, and thus power, to the individual, and that process is also political."

It would appear School House Rock was correct: knowledge is power. Currently in North Carolina, several university institutions are on the chopping block for possible closure, including my Alma mater, North Carolina A&T State University. I no longer believe in accidents of history.

Part of my admiration for Dr. King and everyone of my instructors at A&T that were a part of the movement in one way or another was they all seemed so smart, so well-informed, innately curious about the world around them, and active participants in it through scholarship and the citizenship act of voting for representative government.

These students are articulate, smart, and positive possibilities that you won't see on the "boob tube" flat screen. Forwarded 24/7 are the glorified images of rappers, athletes, entertainers, etc. that of course, doesn't threaten anyone in positions of power: just quaint little minstrel shows; death by a thousand warped cultural knives. I'd rather see more of this kind of "reality show" than the negativity we all seemed to be programmed to accept as our "normal." Of this long list of reality shows, "Myth Busters" is the only one I bothered to watch.

No mention of NSBE, SHPENSBP, NSHP, or what the acronyms mean (see the links). Urban youth in particular are conditioned almost from birth and circumstance to think math and science are "too hard," yet when I taught high school, I'd hear of, or see the same youth spend hours on a joystick mastering "the next level" on a video game. I witnessed the glorification of "flashing sets," "tagging graffiti" and sagging britches to parallel sagging grades: minstrelsy in the hallway. I recall, in all fairness, a staged walkout of Atkins High School because they wouldn't let us wear shorts - that wasn't important either.

We are all part of a "bewildered herd," prodded by the rod and staff of what our socially acceptable stalls are on the "Animal Farm." What we should be teaching is STEM can be as significant as a pillar of fire by night and smoke by day; it can split a sea of reeds and be the modern underground railroad to emancipation. Instead of mastering levels and cypher, we need to master Calculus and Physics!


It makes education...a revolutionary act.

Catharsis...



TECHNOLOGY REVIEW: The Doomsday Argument is the idea that we can estimate the total number of humans that will ever exist, given the number that have lived so far. This in turn tells us how likely it is that human civilisation will survive far into the future.

The numbers are not optimistic. Anthropologists think some 70 billion humans have so far lived on Earth. If we assume that we have no special status in human history, then simple probabilistic arguments suggest that there is a 95 per cent chance that we are among the last 95 per cent of humans that will ever be born. And this means there is a 95 per cent chance that the total number of humans that will ever exist will be less than 20 x 70 billion or 1.4 trillion.

These guys look at the scenario in which many civilisations have evolved throughout the universe, the so-called “universal doomsday” argument. “In that case, we should consider ourselves to be randomly chosen from all individuals in that universe or multiverse,” they say.

Now suppose that the world population stabilises at 10 billion and our life expectancy is 80 years, then the remaining humans will be born in the next 10,000 years. That’s not a long future for humanity. Today, Austin Gerig at the University of Oxford and a couple of pals put forward a new argument with a (slightly) happier ending.

These guys look at the scenario in which many civilisations have evolved throughout the universe, the so-called “universal doomsday” argument. “In that case, we should consider ourselves to be randomly chosen from all individuals in that universe or multiverse,” they say.

In the past, these universal arguments have been no more optimistic than the ordinary ones. They generally state that long-lived civilizations must be rare because if they were not, we would be living in one. What’s more, because long-lived civilizations are rare, the prospects for our civilisation ever becoming long-lived are poor.

This new approach approach allows Gerig and co to take a more fine-grained look at the odds that humanity will survive for much longer in future than it has existed in the past.

The results are complex but their main conclusion gives some reason for hope. “If [the number of existential threats] is not too large, the probability of long-term survival is about a few percent,” they say.


It's comforting to muse that we can actually know the future, and the likelihood of a predicted outcome. We guffaw when the weather anchor "gets it wrong," and somehow think that global warming means if the entire planet isn't becoming the Sahara Desert (and it snows somewhere), there's nothing to it. In the need for accuracy and truth, science revises itself through a rigorous process of peer review, and adherence to The Scientific Method. Modeling and probability always have a margin for error, so in reading the link, think of that.

One of the ways to "increase our odds" is addressing "existential threats" (meteors, nuclear war, pandemics, poverty), and becoming a space faring species. On "a few percent": Growing up under the "duck and cover" drills of the 60s during the Cold War (during which I never thought we had a snowball's chance), I'll TAKE that!

Diagnosing Fusion Plasma...

Scientists at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) and the National Institute for Fusion Science (NIFS) in Japan have developed a rapid method for meeting a key challenge for fusion science. The challenge has been to simulate the diagnostic measurement of plasmas produced by twisting, or 3D, magnetic fields in fusion facilities. While such fields characterize facilities called stellarators, otherwise symmetric, or 2D, facilities such as tokamaks also can benefit from 3D fields.

Researchers led by PPPL physicist Sam Lazerson have now created a computer code that simulates the required diagnostics, and have validated the code on the Large Helical Device stellarator in Japan. Called “Diagno v2.0,” the new program utilizes information from previous codes that simulate 3D plasmas without the diagnostic measurements. The addition of this new capability could, with further refinement, enable physicists to predict the outcome of 3D plasma experiments with a high degree of accuracy.

The researchers employed a mathematical technique called “virtual casing” to develop the new code for 3D fusion plasmas that are in equilibrium. Such plasmas are held steady by the balance between the inward pressure of the magnetic fields that confine them and the outward pressure exerted by the plasma. Virtual casing enabled the researchers to efficiently calculate magnetic diagnostic signals given a simulated plasma. This was achieved by recognizing that the magnetic field at the edge of the simulated plasma was all that was necessary to calculate the magnetic diagnostic signals.

Science fiction? Hardly, and there's more -- It can also desalinate water, be used as flexible water filtration membranes, help recover energy from desalination waste brine, be made into flexible solar cells and can also double the lifespan of lithium ion batteries. With its superior bacteria-killing capabilities, it can also be used to develop a new type of antibacterial bandage.



Scientists at Nanyang Technological University (NTU) in Singapore, led by Associate Professor Darren Sun have succeeded in developing a single, revolutionary nanomaterial that can do all the above and at very low cost compared to existing technology.



This breakthrough which has taken Prof Sun five years to develop is dubbed the Multi-use Titanium Dioxide (TiO2). It is formed by turning titanium dioxide crystals into patented nanofibres, which can then be easily fabricated into patented flexible filter membranes which include a combination of carbon, copper, zinc or tin, depending on the specific end product needed.

Star Trek: Renegades prop fundraiser continues!

The Renegades Team would like to thank all our new backers who have helped raise additional funds for new prop designs. So far, we have raised just over $2700.00. 

Our design team is coming out with new designs almost daily. Apart from new Federation phaser designs, we also have new communicators, Klingon disruptors, Klingon communicators, door panels, data terminals, and a huge prop (over 6 feet tall!) that is ultra top-secret at the moment (hey, we have to save some surprises for the film!)

Props by Scott Nakada

As you can imagine, designing and building a prop from scratch is a long, tedious and expensive process. The first step is the design. This can be the most difficult, according to Renegades Art Director, Scott Nakada. "Star Trek is unique in that it has a certain history behind objects. Keeping the lineage or a look/ design aesthetic can be difficult while simultaneously trying to maintain a look of something fresh and new." It can take anywhere from 3-4 hours, or up to several months to get the design just right.

After the design is approved, the construction begins. A full-color shaded image is converted to black and white for cutting guides at a 1:1 scale. The layers are then separated and printed onto adhesive material. Styrene sheets of various thicknesses are cut to give the various parts their correct dimensions.

STR Combadge Prop

The next stage is the mold. RTV silicon rubber is used. RTV is quite expensive ($160 per gallon!) and is the consistency of thick slime. "I am estimating the film could use 10 gallons of the stuff for the various pieces of work," Nakada says. The styrene parts are then placed into small molding containers made from foam core, then the RTV material is poured over them.

After 24 hours, the mold is set, and a casting polyurethane resin material (also expensive - $145 for two gallons) is poured into the mold. This step must be done very quickly, as it solidifies in 3 minutes!

After about 45 minutes, the prop can be taken out of the mold, but must sit, completely undisturbed for 8-24 hours to reach full hardness. Finally, the prop is painted and sealed. "They are blown free of any surface contaminants, and then painted with a primer layer and several coats of automotive paints, and appropriately colored other paints ranging from acrylics, to airbrush paints of differing types to a simple good old can of Krylon. One prop can use up to 7 different paints and painting techniques," Nakada relates. And if electronics are used, the complexity of the process is increased exponentially. And, of course, the costs of the materials alone are just the tip of the iceberg. There's also equipment, prototyping materials, expendables, etc.

STR Combadge Prop

Please help us create these top-of-the-line, never-before-seen-anywhere-in-Star-Trek props! As you can see, there is much time and effort necessary to do this, and we have a long way to go to reach our $15,000 goal.

And there are rewards for your support! From downloads of the Renegades pilot, to DVDs or Blu-Rays to exclusive Renegades Crew t-shirts, to personally autographed cast photos - there's something for everyone. You can even get one of the props!

Yin and Yang...


Yin and yang are actually complementary, not opposing, forces, interacting to form a whole greater than either separate part; in effect, a dynamic system. Everything has both yin and yang aspects, (for instance shadow cannot exist without light). Either of the two major aspects may manifest more strongly in a particular object, depending on the criterion of the observation. The concept of yin and yang is often symbolized by various forms of the Taijitu symbol, for which it is probably best known in Western cultures. (Wikipedia)

Star Trek Blog: Star Trek’s replicator is an amazing technology concept that has fascinated us for decades. Working at the molecular level to synthesize materials, the replicator is able to instantly produce nearly any object, food or medicine on demand. It is easy to imagine how the replicator would quickly change the world. Such a device could dramatically reduce or even eliminate the cost of most products. Hunger and poverty would be stamped out worldwide, and much of the time and energy spent working for a living could be used instead for pursuits of education, exploration and the advancement of society.

Star Trek envisions the future of humanity to be one of incredible achievements made possible by evolved philosophies as well as technologies. This hopeful view of tomorrow is perhaps the reason so many have dreamed of inventing real-life versions of Star Trek tech -- from the transporter to the tricorder -- and the replicator is one of the most coveted.

A process called “additive manufacturing,” or its more popular nickname, “3D Printing,” has captured the imagination of the tech industry. These machines work much like the two-dimensional printer you may have on your desk, but instead of printing a layer of ink, a 3D printer extrudes many layers of melted plastic to form a physical object. You can imagine this as similar to a hot glue gun, where the heated glue stick is carefully extruded from a nozzle. In the case of a 3D printer, that nozzle is controlled by software and digital design files that tells it how to form a shape.

The comparisons between 3D Printing and the Star Trek replicator don’t end with plastic. Other materials like wood, metal and even some foods are now being extruded in similar ways to make on-demand creations. This has led to excited speculation that soon we may see the beginnings of a new era of manufacturing in America and around the world, where small-scale production is possible at very low costs. We may even “print” biotechnologies and human organs one day.

Gene Roddenberry's underlying message of the future: eternal optimism. As much as I am a fan, I'm afraid I possess a healthy dose of skepticism. Even the Star Trek Memory Alpha Wiki mentions some rough roads prior to 1st Contact with Vulcan. I sincerely hope "life does [not] imitate art" in this case (the "rough road" part; 1st Contact would be OK).

The last five mass extinction events were completely involuntary; unassisted since we hadn't showed up just yet. I end below the embed with two quotes from Einstein:

“I don't know what weapons will be used in world war three, but in world war four people will use sticks and stones.”

"We cannot dispair of humanity, since we ourselves are human beings."

Six-Legged Lizards...


Researchers can learn a lot from a lizard scampering across the hot desert sand or an insect crawling atop a pile of plant litter. Chen Li and colleagues from the Georgia Institute of Technology in Atlanta took cues from such creatures and designed a robot that uses six legs to traverse a bed of dry, loose grains.



The robotic design isn't as effective as a lizard's but it can move through sand at a reasonable pace without getting stuck, and it may help to boost the performance of roving and walking robots, such as the Mars rovers, the researchers said. They noted that previous studies of objects moving through air and water have led to improvements of industrial products such as aircraft wings and underwater robots.



"There's only going to be an increasing number of robots running around our planet and others," said Daniel Goldman, a co-author of the report that appears in the 22 March issue of Science. "We'd like to identify principles that allow devices to move effectively under diverse conditions."

OK let me confess

I am a researcher, not because I am doing a college thesis or a gov job, but because I have a need to know. The problem is that the things we have been called and are called do not fully disclose a remedy to our plight. Not as the overall group we are associated with, not as the various camps within the group. Thus we have no rights or privileges other than what we are allowed by the powers that be (over us as a group).

OK, putting all the recent marbles on the table and keeping it brief:

We got off the boat that came from Africa.

We were here in America already.

We are Africans, Egyptians, Hebrew Israelites, native but Black Indians, Moors, Jewish, Muslim, Christian, others and because each designation has their own myth stories that may or may not link us altogether, we can't agree. Why?

You can not put all of us into the same box if only some of us have that particular history. The group who did come from Africa can not claim oneness with the group that were indigenous Black Americans and so on.

We don't all have the same story and so our masters to keep it simple called us slave names from their property ownership titles to derogatory names. We keep looking for a lumped together name with a common history attached. Slavery is the common experience no matter where we came from. History is most always to make political or religious control or to recover from it. Once written history is not removed. False history is not deleted, just challenged by another perspective. You could be teaching/spreading a lie or a spin-off.

Today we are schooled in all the master's arts and sciences and law. None of this has provided a remedy for us in this country. It should be noted that the main problem is not what we call ourselves among ourselves, but how we are defined in the legal system of the country in the constitutional documents (contracts). Forget about the local law stuff, look at the law that governs the country. As I am not trained in those things I don't have the language skills to comprehend well myself but you lawyers of hue do.

It seems that the American Moorish Movement is heading in this direction. I don't agree with being a Muslim as I am a so-called Christian (don't like that either). I also know these are referring to a more esoteric (cosmic understanding and application) knowledge and not the secular perspective. But, you can't get past names and events attached to names (our slavery started with Muslims, converted Jews and Christians). All the major religions say esoteric knowledge are witchcraft, magic and devil worship. There is much evil in the common religions too! Secret societies had hoarded knowledge, thus inviting corruption and decay of the truth and have abused application. While dispersion of knowledge is not a fruit to the masses, a guiding by wisdom is ignored completely, which is why the whole nation is crumbling.

So what I see is that no matter how we name ourselves we are listed in constitutional documents as property in a corporate institution. That is the problem and we need to see what we need to be to secure our rights under the constitutional contract. That might be the missing 2/5. Today the corporation is restructuring. We might be written out of the new plan or assimilated into the matrix. All us old farts are being put aside because we still remember. Or what if the foreign investment is a guardian, we being the perpetual underage ward (via lame schooling, social confusion, financial disenfranchisement, etc), never realizing this is our country. The renters are tearing up the house we own, we think we are from Europe (we learned (slum-lordism) from them their thoughts). This is our home!?

Lots to sort out, but look at the legal first, the constitutional stuff that established this mess.

There is a new documentary on Angela Davis called “Free Angela and All Political Prisoners” see https://www.facebook.com/freeangelafilm and http://www.imdb.com/title/tt2350432/.  Black Bloggers Connect (see http://blog.blackbloggersconnect.com/2013/03/black-bloggers-connect-presents-free.html) invited people to blog about why such a film is necessary.  The question can be asked, “Do African and African American astrophysicists need to know about Angela Davis?”  My answer is “Yes!” 

 

I had the pleasure of meeting Professor Angela Davis PhD when I was a graduate student at the University of California, Santa Cruz (see http://en.wikipedia.org/wiki/Angela_Davis).  At the time I was playing my role as the first African American graduate student in the Astronomy & Astrophysics department.  I was slowly being worn down by the petty discrimination, insults, and slights that I had to face on a daily basis with no one available within the department with which to decompress.  Enter meeting Dr. Angela Davis and her graduate students.  She and her students helped me put my negative experiences into the context of the USA incarnations of racism, sexism, and who has the right to make new knowledge.  In effect, I learned that what I was experiencing was not specific to just me, UCSC, or to astrophysics.

 

Dr. Angela Davis is an icon of the Black Power movement in the United States, however when you spend your life studying physics and astrophysics...that part of my education was neglected.  All I knew was the outline of who she was, what she had done, and in the mid-1990s when I met her that she had one of the best jobs in the University of California system: an endowed chair.  What I did not understand at the time that became important to me later was that before she became an internationally recognized political figure, she was already a professor at the University of California, Los Angeles; she was already Dr. Angela Davis with a doctorate in philosophy (see
http://histcon.ucsc.edu/faculty/singleton.php?&singleton=true&cruz_id=aydavis).  This point is important enough that I am going to refer to her as Dr. Davis throughout this blog.

 

Meeting Dr. Davis and her intellectual community personally helped me endure a difficult situation long enough to complete my doctorate degree; however, knowing her story is important for our collective Black peers in astrophysics for many reasons, but one stands out.  Mentoring students of astrophysics, the fear emerges of being transformed during the PhD process into someone unrecognizable.  This issue touches on the imposture syndrome (see astrophysicist Dr. John Johnson’s blog on this at http://mahalonottrash.blogspot.com/2012/09/impostor-syndrome.html) which arises from not seeing people like yourself in your profession as well as touches on the fear that in order to succeed in astrophysics you have to ‘whitewash’ yourself.  This whitewashing may include extraction and disassociation from family and community, adopting the value system of the majority, self-imposed silencing on certain topics, and in the extreme the adoption of majority fashion, speaking, and interaction style.  Dr. Davis is our peer in that she earned a doctorate and her working world is academia.  The process of earning a doctorate did not sever her connection to the African American community and did not change her values.  She was and is brave and courageous and willing to stand up for what she believes in and willing to sacrifice a comfortable academic lifestyle in the process. 

 

Dr. Davis is an example for us Black astrophysicists to emulate.  Our cause is that we want more diversity in astrophysics.  Then we have to bring our values with us and we have to not be silent.  We have to insist that our colleagues create an environment that supports all students especially those we are trying to attract to astrophysics.  Dr. Davis had the California government standing against her (and she was on the FBIs Most wanted list!) and she won.  We simply have to stand our ground to our academic colleagues and dare to forego the comfort of our fairly prestigious positions.  I plan to see “Free Angela and All Political Prisoners” when it comes to my town and I know that I will be better educated for it and I will be inspired. I think that the same will be true of the other African and African American astrophysicists if they make the time to see this film.

Cuprates...

Philip Phillips, a professor of physics and of chemistry at Illinois, and colleagues found that something other than electrons carries the current in copper-containing superconductors known as cuprates.

CHAMPAIGN, Ill. — To engineers, it’s a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists at the University of Illinois and the University of Pennsylvania found that for copper-containing superconductors, known as cuprates, electrons are not enough to carry the current.



“The story of electrical conduction in metals is told entirely in terms of electrons. The cuprates show that there is something completely new to be understood beyond what electrons are doing,” said Philip Phillips, a professor of physics and of chemistry at the U. of I.



In physics, Luttinger’s theorem states that the number of electrons in a material is the same as the number of electrons in all of its atoms added together. Electrons are the sub-atomic particles that carry the current in a conductive material. Much-studied conducting materials, such as metals and semiconductors, hold true to the theorem.



Phillips’ group works on the theory behind high-temperature superconductors. In superconductors, current flows freely without resistance. Cuprate superconductors have puzzled physicists with their superconducting ability since their discovery in 1987.



The researchers developed a model outlining the breakdown of Luttinger’s theorem that is applicable to cuprate superconductors, since the hypotheses that the theorem is built on are violated at certain energies in these materials. The group tested it and indeed found discrepancies between the measured charge and the number of mobile electrons in cuprate superconductors, defying Luttinger.

By now you've probably heard about the amazing new cosmic snapshot from the European Space Agency’s Planck spacecraft. It is one of those scientific achievements so mind-boggling that you have to spend a bit of time with it to truly appreciate what you are seeing. This is relic radiation from when the universe was 370,000 years old, still all aglow from the Big Bang. The radiation has been traveling 13.8 billion years since then, across ever-expanding stretches of space, before landing in Planck’s detectors. Then it took a tremendous feat of imagination and insight to translate that noisy signal into a comprehensible map of what the universe looked like in its infancy.



So let’s step back for a moment, look at how this image came to be, and consider some of the more surprising details hidden within it. [Headers lead into the topics]



The map started out as static.

Human brains cannot make sense of all the data from Planck.

The universe is darker, lighter, slower, and older than we thought.

The universe is lopsided.

Chicxulub Snowball...

...the prevailing theory:

 


Current theory:

 

The rocky object that wiped out the dinosaurs 65 million years ago may have been a comet, rather than an asteroid, scientists say.

 

The 112-mile (180 kilometers) Chicxulub crater in Mexico was made by the impact that caused the extinction of dinosaurs and about 70 percent of all species on Earth, many scientists believe. A new study suggests the crater was probably blasted out by a faster, smaller object than previously thought, according to research presented this week at the 44th Lunar and Planetary Science Conference in The Woodlands, Texas.

 

Evidence of the space rock's impact comes from a worldwide layer of sediments containing high levels of the element iridium, dubbed the Cretaceous-Paleogene (K-Pg) boundary, which could not have occurred on Earth naturally.

 

The new research suggests the often-cited iridium values are incorrect, however. The scientists compared these values with levels of osmium, another element delivered by the impact.

 

Their calculations suggested the space rock generated less debris than previously thought, implying the space rock was a smaller object. In order for the smaller rock to have created the giant Chicxulub crater, it had to have been going exceedingly fast, the researchers concluded.

AFRO Flash Fiction

Flash Fiction is gaining popularity at the speed of light on the Internet. FF  is more than simply creating a story with a beginning, middle and end in less than 1000 words. There should be a plot twist and moral. This is a thin slice from the thick juicy part of  a much bigger story; the reader may have to fill in the blanks.

The BSFS has presented  Flash Fiction on its website -- in many excepts or stand alone pieces. This is good. We need to encourage more writers and webmasters to offer AFRO Flash Fiction to readers.

I have posted AFRO Flash Fiction  on my new website: http://www.afroflash.com

As always, I post a link back to BSFS to encourage us all to reach out and let others know that African Diaspora Speculative Fiction  is trending upwards.

Einstein, Entropy and Information...


...as explained by one of the smartest physicists I know!

James Clerk Maxwell formulated the equations that describe electricity and magnetism. He was Einstein's hero! Both are the reason why we're in the age of laptops and I-phones.

Physics Colloquium, University of Texas Physics Department. Mark has a process that's a little more efficient than Steven Chu's (yes, THAT Steven Chu). It's worth your time to watch this presentation, and seek out colloquium wherever you are. Science is open and a social endeavor.

Something I used to enjoy in Texas, that I admittedly miss...

Surely Not Joking...

Electrons traveling through two slits and a single slit

Physicists in the US and Canada say that they have done the best job yet of realizing Richard Feynman's famous thought experiment about how single electrons pass through two slits. Although the researchers are not the first to recreate the experiment in the lab, they say that their incarnation best captures the essence of the original exercise.

 

Feynman originally outlined his thought experiment in volume three of his famous series The Feynman Lectures on Physics as a way of illustrating wave–particle duality in quantum mechanics. In the book, he invites the reader to imagine firing individual electrons through two slits and then marking the position where each electron strikes a screen behind the slits.

 

After many electrons have passed through the slits, the marks on the screen will comprise a diffraction pattern – illustrating the wave-like behaviour of each electron. But if one were to cover up one of the slits so that each electron could only pass through the other slit, the diffraction pattern would not appear – showing that each electron does indeed travel through both slits.
