life is in the cracks

We call them the lucky ones. They seem to go through life without a hitch. They have perfect attendance and teeth. They do 4 years of college without diversion or perversion or depravity, get a nice job and a house and 2.5 kids, a dog and a ritzy car. How in the heck do you get a .5 kid I don't know. There is something about statistical average persons, the real super humans we all are striving to match up to.

Me, I envy them and sneer at them. I live in the cracks between dreams, with allowances, exceptions, quick fixes, rescues, interventions, set asides, and wits. I use my wits and survival skills. That is when I'm made aware by the statistical average man I'm in a rut. A crack, a crack I have slipped through to where my head is no longer visible to the general public. That is, the paper trail they use to keep tabs on us and the pedigree of the super human race the statistical average man. Oh he is real, he exists alright. When they do the numbers he stands up tall as big as life. He is the conglomerate of every positive thing in our society. He is admired by every seeking forward reaching creature on the planet. Damned be you if you diss them. 

The super ones aren't perfect or so it is said, 99.999% pure + or -.001%. I am always confronted with the plus side one who is a little more than perfect. I just have to ask why. Why are the ruts, the cracks so crowded. Why so few of us stay on top. Momentary elevation of persons become the idol of us all. So and so made it. Then in retrospect, where is so and so today? Did they become one with the super humans of the statistical average? Or did they fall back through the cracks, or into the ruts where the rest of us live?

ATRAP for Antiprotons...

Figure 1: (a) The CPT symmetry can be likened to a mirror that reflects spatial coordinates, flips charge and other additive quantum numbers, and reverses time. To test for cracks in this CPT mirror, physicists check whether the magnetic moment of the proton (left) has the same magnitude as that of the antiproton (right). (Technically, the moments have opposite signs due to the way magnetic moment is defined relative to the spin.) (b) To measure the antiproton’s magnetic moment, the ATRAP Collaboration measures the cyclotron and spin-flip frequencies, fc and fs, respectively. The ratio of these frequencies gives the antiproton’s magnetic moment, μp¯=-fsfcμN, in terms of the nuclear magneton μN.

The ATRAP Collaboration has measured the magnetic moment of the antiproton more precisely than ever before, allowing a new test of CPT symmetry.



Many physical laws are indifferent to distinctions such as left or right and forwards or backwards. On rare occasions, though, a discrepancy shows up, and we say that a symmetry is broken. One symmetry that has so far avoided any signs of breaking is the so-called CPT symmetry, which equates matter and antimatter at a fundamental level. A new test of CPT symmetry involves antiprotons. Specifically, Jack DiSciacca of Harvard University and his colleagues (the ATRAP Collaboration) present the most precise measurement to date of the antiproton magnetic moment [1]. As reported in Physical Review Letters, the results match data on the proton, thus extending CPT ’s shatterproof status for the time being.



Look into a mirror and imagine the world on the other side is not just a reflection, but instead a real physical world. Should nature behave differently in this mirrored world? For decades, most physicists believed the answer was “no.” They assumed that nature was the same in a coordinate system and its mirror image, and they even gave this supposition a name: parity reversal symmetry or P symmetry. However, in 1957, the nuclear physics world was rocked when two back-to-back articles in Physical Review revealed that P symmetry was violated by nature [2, 3]. This discovery revolutionized the understanding of the weak interaction.

As a member of BSFS and a self-proclaimed Scifi fan and writer I would encourage everyone to keep their eyes focused on Star Trek: Renegades. The production is moving forward and being produced as a pilot for a web series which seeks to explore the more complex motivations of a renegade Star Fleet crew that will be compelled to take unorthodox and possibly unethical actions to preserve an under attack  Federation. (http://startrekrenegades.com/home/).

Star Trek:Renegade is directed by (one of my personal favorites) Tim Russ, who also directed Star Trek: Of Gods and Men (http://startrekofgodsandmen.com/main/) and who the viewing audience will recognize as Lt. Commander Tuvok from the Star Trek: Voyager series. Opportunities for black individuals in the director's chair don't come along as often as we would like, so when they do we should take note, and if the project appeals to us - we should give it our support, not simply in kickstarter funds but also by being as vocal as we can in sharing information about the project is as many venues as we can conceive of!

Diagnosing Fusion Plasma...

(Photo Credit: Graphic by Sam Lazerson)

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.

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.

Planck's Four Surprises...


Lopsided universe: Planck’s new skymap shows that one half of the microwave background is brighter than the other, and the universe has a large cold spot. Credit: ESA and the Planck Collaboration

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.

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.

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.

Phaser Effect...



The theoretical foundations for the laser were established in 1917, when Einstein formulated the quantum theory of radiation, describing the absorption, spontaneous emission, and stimulated emission of electromagnetic radiation. Its realization stayed hidden for decades, however, before it emerged in the form of masers and lasers, which emit microwave and visible radiation, respectively. The range of emitted frequencies was soon broadened to cover wavelengths from the infrared to the x-ray range, and lasing was extrapolated beyond the realm of optics. Free-electron lasers, in which the active medium is a relativistic electron beam, helped cover extreme wavelength ranges and are now the basis for a new generation of experimental facilities for x-ray experiments. Atom lasers—emitting matter waves instead of photons—have also been demonstrated. Recently, the laser idea was extended to sound waves, leading to the conceptualization of the acoustic analog of a laser, which emits phonons (lattice vibrations) instead of photons. Now, writing in Physical Review Letters, Imran Mahboob at the NTT Basic Research Laboratories, Japan, and colleagues report on the experimental demonstration of a purely mechanical counterpart of a three-level laser scheme [1]. The device, excited by acoustic vibrations, amplifies sound waves through stimulated emission of phonons and acts as a phonon laser: a spectrally pure source of phonons with a frequency of around 1.7 megahertz (MHz).



What is the appeal of phonon lasers? One potential advantage is that their emission has smaller wavelength than that of photon lasers at the same frequency because the sound speed is much smaller than the speed of light. This could help improve the resolution of tomographic, ultrasound, and other imaging techniques. In analogy with their optical cousins, phonon lasers might deliver directional and coherent acoustic beams, which could be coupled to nanoscale mechanical engines or used in communication networks based on acoustic waves. But as the history of optical lasers suggests, most applications of future phonon lasers may be completely unexpected.

The Trekkie in me notes: from the phonon pump, the upper-to-intermediate level transition is called "Phaser Emission." Wonder if there's a stun setting?

Photo Realistic Art

 

 

Kelcin Okafor

 

"We've seen our fair share of talented photorealist artists go viral, from Paul Cadden to Diego Fazio. But never before have we been privy to the painstaking process of creating such a detailed masterpiece. That is, until we discovered Kelvin Okafor's videos."

"The London artist's hyperrealistic graphite drawings look far more like photographs than pencil on paper. For skeptics, Okafor provides proof of his works' handmade history by posting the evolution of his pieces online, via photos on his blog and through entrancing YouTube videos."

"The artist describes himself on Twitter as "highly interested in detail and precision," and we can't help but agree."

Omega Nexus! Omega Awesome!

Last year I watched the best superhero movie I’d ever had the pleasure of seeing: The Avengers. Very recently I finished reading a book that if turned into a live action movie would be a sweeping effects laden spectacle on par with-even exceeding the Avengers. The Omega Nexus, by Roger Reece and Peter Reece, centers around a young man named Ty Slade who discovers that he is an Ascended, a human being with extraordinary abilities. Eventually, circumstances force him to reunite with members of a group also possessing Ascended abilities. The group, called the Omega Nexus, is led by a brilliant scientist, Dr. Brown who, during the Cold War, worked in a secret government program tasked with creating super soldiers. His former partner turned enemy, General Lassiter, controls an opposing organization bent on using Ascended persons to conquer the world.

From there, the action is fast, furious and uncompromising. The superhero/villain clashes explode from the pages with an intensity that brings to mind episodes of Justice League. Omega Nexus is a fun page-turner with the promise of more sequels to come. I’ll be waiting!

Fermi Bubbles, Dark Matter...



In 2011, an analysis of data from a NASA Fermi Gamma-Ray Space Telescope turned up massive, previously unseen galactic structures. A group of astrophysicists located two massive bubbles of plasma, now know as "Fermi Bubbles," each extending tens of thousands of light-years, emitting high-energy radiation above and below the plane of the galaxy. The structure spans more than half of the visible sky, from the constellation Virgo to the constellation Grus, and it may be millions of years old.

 

Now, more recently, in 2013, astrophysicists Dan Hooper of Fermi National Accelerator Laboratory and Tracy Slatyer at Princeton University, have published a study suggesting that a massive outflow of charged particles from Fermi bubbles, as they are known, outflows of charged particles (gamma rays) traveling at nearly a third the speed of light from the center of the Milky Way galaxy, may be partly due to collisions between dark matter particles that result in their annihilation, and the subsequent creation of the building blocks of visible matter—charged particles that appear as two lobes or "bubbles," above and below the center of the Milky Way Galaxy.

 

Another possibility includes a particle jet from the supermassive black hole at the galactic center.

Atomic Collapse...

An artificial atomic nucleus made up of five charged calcium dimmers is centered in an atomic-collapse electron cloud (Image courtesy of Michael Crommie) 



The first experimental observation of a quantum mechanical phenomenon that was predicted nearly 70 years ago holds important implications for the future of graphene-based electronic devices. Working with microscopic artificial atomic nuclei fabricated on graphene, a collaboration of researchers led by scientists with the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have imaged the “atomic collapse” states theorized to occur around super-large atomic nuclei.



Atomic collapse is one of the holy grails of graphene research, as well as a holy grail of atomic and nuclear physics,” says Michael Crommie, a physicist who holds joint appointments with Berkeley Lab’s Materials Sciences Division and UC Berkeley’s Physics Department. “While this work represents a very nice confirmation of basic relativistic quantum mechanics predictions made many decades ago, it is also highly relevant for future nanoscale devices where electrical charge is concentrated into very small areas.”



Crommie is the corresponding author of a paper describing this work in the journal Science. The paper is titled “Observing Atomic Collapse Resonances in Artificial Nuclei on Graphene.” Co-authors are Yang Wang, Dillon Wong, Andrey Shytov, Victor Brar, Sangkook Choi, Qiong Wu, Hsin-Zon Tsai, William Regan, Alex Zettl, Roland Kawakami, Steven Louie, and Leonid Levitov.



Originating from the ideas of quantum mechanics pioneer Paul Dirac, atomic collapse theory holds that when the positive electrical charge of a super-heavy atomic nucleus surpasses a critical threshold, the resulting strong Coulomb field causes a negatively charged electron to populate a state where the electron spirals down to the nucleus and then spirals away again, emitting a positron (a positively–charged electron) in the process. This highly unusual electronic state is a significant departure from what happens in a typical atom, where electrons occupy stable circular orbits around the nucleus.

Peter and the Little Boy Eater

Every couple years I dust this story off and see if there’s anything I can do with it.  I wrote Peter and the Little Boy Eater for a correspondence class I was taking (Children’s something or other) way back in ’98 or so.  It’s gone through several iterations, including an almost complete rewrite after I lost the revision I was happy with.

But every time I sent it to an agent or a publisher, I always got a rejection.  I never got a specific reason why, but it never went anywhere.  Yesterday, while out with my ladies, we stopped at Barnes and Noble.  We were in the children’s section and I was walking around with my daughter when I spotted the book, I Need My Monster. My wife and I both read it and the first thing that popped into my head was, ‘Hey, this might not be a bad place to submit my children’s story to’. 

After getting home, I opened it, read it over a little, got on Flashlightpress.com’s website and looked over a few of their titles.  Even though Monster seemed in the same vein, I wasn’t sure about mine because it’s a rhyming children’s story.  But what do you know, they have a book titled, That Cat Can’t Stay and it’s told in rhyme!  So I’ve already sent this off as of Sunday night and hopefully I’ll hear something positive in the next couple weeks.
