Sugar Star...


...if humankind were to ever travel 400 light years, at least we wouldn't have to pack a lunch!

(Yeah, that was POP-corny!) Smiley It's Friday though...
Astronomy and ESO

A team of astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) has spotted sugar molecules in the gas surrounding a young Sun-like star. This is the first time sugar has been found in space around such a star, and the discovery shows that the building blocks of life are in the right place, at the right time, to be included in planets forming around the star.

 

The astronomers found molecules of glycolaldehyde — a simple form of sugar — in the gas surrounding a young binary star, with similar mass to the Sun, called IRAS 16293-2422. Glycolaldehyde has been seen in interstellar space before, but this is the first time it has been found so near to a Sun-like star, at distances comparable to the distance of Uranus from the Sun in the solar system. This discovery shows that some of the chemical compounds needed for life existed in this system at the time of planet formation.

Commentary...


USA Science and Engineering Festival - Facebook

Reading a lot of blogs as well as web sites for this one, I came across "Physics and Physicists" entry by ZapperZ (yes, that's the PhD's post name) titled: "Science Is Not Cool."

The entry relates somewhat to the recent landing of the Curiosity Rover on Mars, which I posted as I was watching the touchdown @ 1:30 AM EST. Times I wish I lived on the west coast!

Adam Ruben, PhD in Microbiology, is the original author of the title piece on the American Association for the Advancement in Science (AAAS for short) "Issues and Perspectives" piece.

At first, I thought about ignoring it. Then, I couldn't help commenting on Zapper's entry, which he graciously published. It follows:

I am in agreement. Along with our advancement through the atomic age post “Sputnik moment,” there has been an attention deficit noticeably spread among the population. Our secondary education is affected by inane standardized tests that point to nowhere measuring [not] anything of global competitive importance; all STEM careers must be “fun” to compete with Xbox, Play Station, You Tube, Facebook, Twitter and “the Google.” A picture of the Apollo landing and an astronaut next to the lunar module is captioned: “This was done with a slide rule. Your eight grader has more computing power in his cell phone, and still can’t pass math because he won’t do more than fifteen minutes of homework. Where do you think HE’LL be going?” Alas, it is the technology birthed of a lot of science behind their genesis that is our undoing. Two good reads: the first Neil Postman's "Amusing Ourselves to Death: Public Discourse in the Age of Show Business." Even though he was referring to the news media in the advent of cable television (written in the early eighties), it is easy to extrapolate to the current technology and its effects on the populace. The second is “The Dumbest Generation: How the Digital Age Stupefies Our Youth and Jeopardizes Our Future (Or, Don’t Trust Anyone Under 30),” by Mark Bauerlein.

Ironic, as my Google ID is "Cool Physics." I'm sure that was a qualifier for ZapperZ posting it.

I have a lot of fun, posting what I think or what I've read, and obviously, my fascination with science. That fascination is shared with a lot of people that view this blog.

Adam Ruben is also a stand-up comedian, and has written a humorous book "Surviving Your Stupid, Stupid Decision to Go to Grad School." I put him in the company of Jorge Cham of PhD Comics (PhD in Robotics from Stanford) and Scott Adams (former engineer for Pac Bell), cartoonist for Dilbert. Each are saying science and engineering are human experiences, and humanity also involves humor.

For myself, it was the finding of humor in things that got me a degree in physics in the first place, and keeps me pressing forward with the wonder of a child opening wrapped presents (metaphorically, an 'onion'). It is my hope to share that wonder; making STEM a more human experience...for everyone.

One-Molecule Thick...

International Molybdenum Association

MIT researchers produce complex electronic circuits from molybdenum disulfide, a material that could have many more applications.

CAMBRIDGE, Mass. — The discovery of graphene, a material just one atom thick and possessing exceptional strength and other novel properties, started an avalanche of research around its use for everything from electronics to optics to structural materials. But new research suggests that was just the beginning: A whole family of two-dimensional materials may open up even broader possibilities for applications that could change many aspects of modern life.


The latest “new” material, molybdenum disulfide (MoS2) — which has actually been used for decades, but not in its 2-D form — was first described just a year ago by researchers in Switzerland. But in that year, researchers at MIT — who struggled for several years to build electronic circuits out of graphene with very limited results (except for radio-frequency applications) — have already succeeded in making a variety of electronic components from MoS2. They say the material could help usher in radically new products, from whole walls that glow to clothing with embedded electronics to glasses with built-in display screens.

Fractal Calculus...

WEST LAFAYETTE, Ind. - Many researchers studying superconductivity strive to create a clean, pure, perfect sample, but a team of physicists found that some flaws might hold the key to a material's unique abilities.


Erica Carlson, a Purdue University associate professor of physics, led a team that mapped seemingly random, four-atom-wide dark lines of electrons seen on the surface of copper-oxygen based superconducting crystals. The team uncovered a pattern in these flawed lines, which are separate from the expected structure of the material, and discovered that they exist throughout the crystal. The findings suggest the lines could play a role in the material's superconductivity at much higher temperatures than others.


"This material is ceramic, like your dinner plates, and it has no business conducting electricity, but under the right conditions it conducts electricity perfectly with zero energy loss," Carlson said. "A better understanding of how and why this superconductor works could help us design better ones. If we can create a superconductor that works at high enough temperatures, it could transform how we use and generate energy."

Life imitates art.


Wikipedia: Anti-mimesis is a philosophical position that holds the direct opposite of mimesis. Its most notable proponent is Oscar Wilde, who held in his 1889 essay The Decay of Lying that "Life imitates Art far more than Art imitates Life". In the essay, written as a Platonic dialogue, Wilde holds that such anti-mimesis "results not merely from Life's imitative instinct, but from the fact that the self-conscious aim of Life is to find expression, and that Art offers it certain beautiful forms through which it may realise that energy."

6He to 6Li...


Decays of atomic nuclei are potential sources of information on fundamental phenomena occurring in the quantum world. Unfortunately it is a rather difficult task to model such processes. Yet National Centre for Nuclear Research (NCBJ) physicists have successfully simulated the process of neutron→proton conversion in singly ionized 6He atom nucleus and correctly predicted its impact on the atomic orbital sole electron. Theoretical calculations were recently confirmed by an experiment performed in the GAEN accelerator centre in Caen (France). That way the sudden approximation calculation method (one of the oldest methods employed to solve quantum mechanics problems) was directly validated.

 

Nucleus of a 6He ion is composed of two protons and four neutrons. In a singly ionized ion the nucleus is orbited by a single electron. Surplus of neutrons makes such nuclei unstable, they undergo the so-called beta-minus decays in which one of the neutrons is transformed into a proton. To preserve electric charge, an electron is emitted from the decaying nucleus. Each emitted electron is accompanied by an electron anti-neutrino. In effect, a stable 6Li nucleus (still orbited by a single electron) is produced.

I Still Have My Slide Rule...


July 20, 1969 was a Sunday. NASA interrupted my cartoons on Saturday. I didn't mind. My parents were transfixed as well. The world east of US52 in Winston-Salem, NC seemed to slow; each moment savored, each conversation focused on this one event. Unlike the social stratification we "enjoyed," we weren't alone.

Like no other event before it or since, the world's attention was riveted, not on war, but scientific achievement; not on Vietnam or Civil Rights protests - both important - but on a future we could all collectively hope for. We'd pay attention to a cancelled Sci-Fi series - Star Trek - a little closer.

And I realized what I wanted to be.

I still have my slide rule. Godspeed Neil Armstrong...

Another Reason to Major in Physics...


BUZZ Blog: GRE scores can make or break a graduate school application, so how should students prepare? Although there are a plethora of study books and materials available, decisions made freshman year may determine your score more than your cramming habits weeks before the test.


Ever year, the Educational Testing Service — the organization behind the GRE — releases scores for the general test and categorizes them by the test takers' intended graduate major. Although the GRE made significant revisions to the test this academic year, one fact remains: Physics and philosophy students still rocked the test. Physics majors tied for first in the math section, and philosophy students topped the verbal and writing sections.


Physicists even beat most majors in the verbal and writing sections — a measure of physics majors' stereotypically weak communication skills. Maybe physicists are more well-rounded than pop culture suggests.

CZTS...

Technology Review

IBM says it has made technical progress on a solar technology that researchers hope will yield efficient thin-film solar cells made from abundant materials.

 

IBM photovoltaic scientists Teodor Todorov and David Mitzi on Friday detailed the findings of a paper that showed the highest efficiency to date for solar cells made from a combination of copper, zinc, tin, and selenium (CZTS). Published in Advanced Energy Materials, the technical paper described a CZTS solar cell able to convert 11.1 percent of solar energy to electricity.

As Monarch Butterflies...


Monarch butterflies travel thousands of miles before seeding forward, and...dying.

Perhaps the first starships will be one-way, a beneficial self-insurance of survival.

Sadly, the conundrum would be "who," birthing an interstellar caste system...I can see the lottery/survival/reality show. Joy...

Of course, any sentient inhabitants may not meet our new "Mayflower" with a welcome party, nor assist us through the harshness of a new world. Or, landing during the planet's Jurassic period could be kind of...dicey!

Amazon and Rosie...

Robot ready: Robots made by Kiva Systems move product shelves on a warehouse floor. Amazon bought the company earlier this year in a step toward automating its distribution system and reducing labor costs.

Technology Review: In Automate This, a book due out next month, author and entrepreneur Christopher Steiner tells the story of stockbroker Thomas Peterffy, the creator of the first automated Wall Street trading system. Using a computer to execute trades, without humans entering them manually on a keyboard, was controversial in 1987—so controversial that Nasdaq pressured him to unplug from its network. Then, with a wink, Peterffy built an automated machine that could tap out the trades on a traditional keyboard—technically obeying Nasdaq rules. Peterffy made $25 million in 1987 and is now a billionaire.

Chapter 1: The Rise and Fall of the Union
In the last twenty years an industrial revolution has been taking place in the United States at a pace faster than that of any country in the world, transforming social layers of this country on a scale never before dreamed of. So fast has this industrial revolution been developing that 60 percent of the jobs held by the working population today did not even exist during the First World War, while 70 percent of the jobs that existed in this country in 1900 don't exist today. Not only have work classifications been fundamentally altered, but the work force has multiplied from 20 million in 1900 to 40 million in 1944 to 68 million today. The change is not only in numbers. Over 20 million of those working today are women, and by 1970 it is expected that women workers will have increased to 30,000,000—a work force of women which will be one-and-a-half times the entire work force of 1900.

 

The United States has transformed itself so rapidly from an agricultural country to an industrial country, and as an industrial country has undergone such rapid industrial revolutions that the question of who is in what class becomes an ever-wider and more complicated question. Today's member of the middle class is the son or daughter of yesterday's worker.

Nerds are NOT Dull...

Scientists using a novel printing method have managed to make a color image whose resolution approaches the maximum theoretical limit. The Singapore team published their work in Nature Nanotechnology earlier this week.



Wired breaks down the science pretty well: the team created pixels using “nanoscale posts, with silver and gold nanodiscs on top.” How far apart these posts are, as well as their diameter, determines what color light they reflect. The pillars are all of a nanometer tall. The image’s resolution, in the end, is 100,000 DPI (dots per inch).



The last curious element of this story is the image the scientists chose to reproduce: an image of Lena Soderberg, a Swedish model who posed in 1972 for Playboy. This image (from the neck up, mind you) is actually canonical in computer imaging circles. It all started in 1973, when an imaging scientist at USC was looking for good image to scan for a conference paper. Reported Jamie Hutchinson in 2001: “They had tired of their stock of usual test images, dull stuff dating back to television standards work in the early 1960s. They wanted something glossy to ensure good output dynamic range, and they wanted a human face. Just then, somebody happened to walk in with a recent issue of Playboy.”



From that point on, use of the Lena picture in imaging circles grew, until it simply became standard.

Book of Life...

DNA can be used to store information at a density about a million times greater than your hard drive, report researchers in Science today. George Church of Harvard Medical School and colleagues report that they have written an entire book in DNA, a feat that highlights the recent advances in DNA synthesis and sequencing.



The team encoded a draft HTML version of a book co-written by Church called Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves. In addition to the text, the biological bits included the information for modern formatting, images and Javascript, to show that “DNA (like other digital media) can encode executable directives for digital machines,” they write.

The Next Phase...


We set sail on this new sea because there is new knowledge to be gained, and new rights to be won, and they must be won and used for the progress of all people. For space science, like nuclear science and all technology, has no conscience of its own. Whether it will become a force for good or ill depends on man, and only if the United States occupies a position of pre-eminence can we help decide whether this new ocean will be a sea of peace or a new terrifying theater of war. I do not say that we should or will go unprotected against the hostile misuse of space any more than we go unprotected against the hostile use of land or sea, but I do say that space can be explored and mastered without feeding the fires of war, without repeating the mistakes that man has made in extending his writ around this globe of ours.

 

There is no strife, no prejudice, no national conflict in outer space as yet. Its hazards are hostile to us all. Its conquest deserves the best of all mankind, and its opportunity for peaceful cooperation many never come again. But why, some say, the moon? Why choose this as our goal? And they may well ask why climb the highest mountain? Why, 35 years ago, fly the Atlantic? Why does Rice play Texas?

 

We choose to go to the moon. We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.


President John F. Kennedy

I was a year and almost a month old when these words were spoken. They stir emotion, excitement and vision; hope and direction. As I read them for this post, I wept quietly.

"...not because they are easy, but because they are hard..."

It was not advanced robotics and transistorized super computers that allowed Mercury, Gemini and Apollo: it was grit, sweat, and knowledge of how to compute with a slide rule. It was during a time of social upheaval, physical and brutal de facto segregation and the struggle for Civil Rights. It was during an era a short-lived cancelled show - Star Trek - which later became a cult phenomenon in that we might actually survive the dark corollary of the Drake Equation. It was before our politicians became more concerned with job security than problem-solving; speaking-to-the-base in soundbite talking points versus reaching consensus. It was before a cottage industry of standardized testing gave us fifty inane yardsticks without a national standard but a nebulous goal birthed of sloganeering: No Child Left Behind (or, No Child's Behind Left).

It was before our answers had "Google" in the lexicon; post "Sputnik moment" of fear turned inspiration, when we plunged head long with only one driving directive:

Never Enough...

LHC: Phys.org

Apparently discovering a Higgs-like particle isn’t enough for the physicists working at the CERN facility, now another team working with the LHC has broken the record for the hottest manmade material ever.

Old record: four trillion degrees Celsius: 4,000,000,000,000 = 4 x 1012 oC

New record: ~ in the range of five and a half trillion degrees Celsius, a bump up of some thirty eight percent.

The three teams working at CERN, ATLAS, CMS and ALICE are all working on the same basic problem, figuring out what existed just after the Big Bang so as to better understand how matter works at the subatomic level. ATLAS and CMS were recently in the news of course for finding evidence of particles that strongly resemble the notorious Higgs boson. Meanwhile the ALICE team has been hard at work smashing lead ions into one another creating quark-gluon plasma, material that is being described as a primordial soup, because it is believed to be similar to the stuff that came about right after the Big Bang, and because unlike protons and neutrons, they are believed to move around freely, rather than existing as a bound material.

Identity Crisis...

USA Science and Engineering - Facebook

My first experiment was with a chemistry set.

I wasn't successful, because my impatience at ten-years-old did not allow me to take the time to "read" the manual instructions on what chemicals NOT to mix. The result was an impressive explosion that stained the roof of my room (and luckily, didn't kill me). My parents, though concerned, did not discourage my pursuit of knowledge. They did even more so, closely supervise all my future experiments.

There is a delicate balance between engineering and science. Engineering by definition is: "the art or science of making practical application of the knowledge of pure sciences, as physics or chemistry, as in the construction of engines, bridges, buildings, mines, ships, and chemical plants." Dictionary.com

There is an "art" to taking data and working it into something that translates into a product. I'm not belittling that at all.

By definition, engineering is kind of a bottom-line profession. You may have the STEM background to think like an scientist: but as an engineer, you have deadlines, deliverables, timelines and a budget. Engineers move from project-to-project; scientists may work on one or two, each with a genuine interest, an "assigned curiousity" (Ref: Disciplined Minds). Rarely do engineers win the Nobel Prize. One profession moves mankinds' overall knowledge of nature; the other the next generation of I-Pad.

Thus, the lense we judge science through is becoming the same as the Hedge Fund manager or stock investor's: that would be wrong-headed. This is unfortunately the impact of corporate research dollars swiftly replacing academic grants. It would reduce scientists to bottom-line university engineers, and devoid us all of the youthful joy of the pursuit of knowledge for knowledge's sake - hopefully minus any explosions.

My palindrome post: 868.

A fathom (abbreviation: ftm) = 1.8288 meters, is a unit of length in the imperial and the U.S. customary systems, used especially for measuring the depth of water.


On a voyage to New Orleans down the Mississippi, steamboat pilot Horace E. Bixby inspired Twain to become a pilot himself. A steamboat pilot needed to know the ever-changing river to be able to stop at the hundreds of ports and wood-lots. Twain studied 2,000 miles (3,200 km) of the Mississippi for more than two years before he received his steamboat pilot license in 1859. This occupation gave him his pen name, Mark Twain, from "mark twain," the cry for a measured river depth of two fathoms. (Wikipedia)

Today is my 50th birthday. I was born on a Tuesday, the day before a full moon.

So in celebration of living half a century in reasonably good health, I depart from physics ever so slightly. Mark Twain apparently loved science and technology, balancing friendships with both Nikola Tesla and Thomas Edison (the AC/DC war rivals).


"My boy: you are a thinker," I recall my father saying to me. I do think on things deeply, and sometimes pour into paper/cyberspace what I don't think to say publicly or personally.

I am Ronin. I am also Giri. I say that with some sadness, chagrin, satisfaction, double entendre and satire. I do not say it, however with regrets.

Living half a century does give one the licence to look back on the achievements and mistakes of one's life, and consider the lessons learned.

The poorest people in the world face additional hunger as the price of staple foods soar.

The growth of crops in 2012 has been badly affected by drought in the US and Russia and prices have risen 50% since June.

According to a report about the hike in food prices, from the international agency Oxfam, 40% of US corn stocks are currently being used to produce fuel.

The US Renewable Fuel Standard mandate requires that up to 15 billion gallons of domestic corn ethanol be blended into the US fuel supply by 2022.

The chairman of the world's largest food producer is highly critical of the rise in bio-diesel.

Peter Brabeck-Letmathe of Nestle says crops produced for biofuel use land and water which would otherwise be used to grow crops for human or animal consumption.

His comments have ignited discussion about the second generation of biofuels.
