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...

Source: Decoded Science

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:

...it's Friday!


At this posting: my youngest son is on a plane to Texas back to school. My oldest son is married, stationed in Oklahoma.

A career in science allowed me to see this wonder, show it to my wife and child. The chart I saw said its volumetric rate was 3,160 tons per second. That's all the physics I want to mention.

 

In science one tries to tell people, in such a way as to be understood by everyone, something that no one ever knew before. But in poetry, it's the exact opposite. Paul Dirac

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.

Plus, as I age, I am using the licence to not care what others think about how I apply those lessons...Smiley

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.

Physics World: Probing Single Atoms


Quote for the post title from a talk given at Cal Tech by Richard Feynman.


Researchers in Japan are the first to have succeeded in detecting single atoms using X-ray spectroscopy. Although a difficult technique, the work is an important step forward in studying and characterizing nanoscale structures and devices using X-rays.

 

Previous work in this field has largely focused on using electron energy-loss spectroscopy (EELS) to detect single lanthanide metal atoms and light atoms like carbon. However, EELS can only be applied to certain elements thanks to the high-energy beams used in this method that can damage samples. Nobel metals, such as gold and platinum, are also difficult to detect with high sensitivity using EELS – a major drawback when it comes to investigating meteorites, catalytic clusters or anticancer drugs, where only a very small number of noble metals are looked at in any given sample.

1st Nanowire Logic Gate


This is huge! Dopants require introducing impurities with high temperatures and energies. This should, in theory, have some impact on the final cost (though with all the functionality, I think they'll find a way to charge top dollar). However, it does make it more "green tech" in a sense...and reduce the cost of industry OSHA compliance. Again, I am enthusiastically hypothesizing; dreaming future jobs.
Technology Review

Silicon nanowires are one of the great hopes for electronic devices of the future. Unlike features carved using photolithography, nanowires are easy to make on a nanometre scale. Electronic engineers hope to use them for everything from optoelectronics to biochemical sensing.

But there's a problem because at the nanometre scale, the electronic properties of silicon can depend on the precise location of only a few dopants. That's difficult to control and causes wide variation in device performance.

Consequently, nobody has been able to make reliable diodes, transistors or logic gates out of silicon nanowires.

Today, Massimo Mongillo et amis at the Universite Joseph Fourier, Grenoble, in France demonstrate a way out of this conundrum. These guys show how to fabricate diodes and transistors from undoped silicon nanowires and how how such devices can be wired together to make logic gates.

We now have a much clearer idea of how American astronauts will get into orbit in the coming years.

Nasa has selected three companies to help develop launch systems that can take people to the space station.

They include the SpaceX firm, which recently sent an unmanned cargo capsule to the 400km-high outpost.

But agreements have also been signed with aerospace giant Boeing and the Sierra Nevada Corporation. The latter has a design for a mini-shuttle.

We Are All Sikhs...

Sikhism message of love

After 9-11, the French newspaper Le Monde had the title: "We Are All Americans"; "Siamo Tutti Americani" in Italiano. Suddenly, we'd become Israeli, Egyptian, Irish, British, Roman et al: a long list of countries that suffered terrorist attacks.

Two weeks after Colorado, we're here again: 6 souls versus 12; worship versus movie premire; peaceful immigrants versus Sci-Fi Action fans.

I list here some of the tenets of the Sikh faith. I ask if this, their color or culture, is reason to attack a house of worship, as if there is ever any good reason for violence:

1) One Source
One God is the Creator of the Universe.

2) Equality
All human beings are equal
People of all religions and races are welcome in Sikh Gurdwaras.
Women have equal status with men in religious services and ceremonies.

3) Human Life Precious Above Other Life
The human life is supreme and it is through this life that we can achieve oneness with God's will. Finding God in this life and living by his commands helps us to attain God's mercy.

4) Defending Against Injustice
Sikhs are a peace loving people and stand for Truth and Justice Guru Gobind Singh Ji said, "It is right to use force as a last resort when all other peaceful means fail."

Start-Up Moolah...


The Superconducting Super Collider in Waxahatchie, Texaswas supposed to be where we'd discover the Higgs Boson. My wife's cousin was employed as an engineer there at the time before the budget ax. Thus, CERN and the Large Hadron Collider got the honor of discovering what gives mass well...mass.

Peter Higgs will likely get the Nobel Prize as will the researchers that confirmed his theories; Europe will become a Mecca of particle physics and science research. That will impact their educational curriculum, pedagogy and how they prepare their students to meet the demand of a complex world, learning how to problem solve, a skill becoming bereft in the US relegating evolution to "just [a] theory," the earth to 6,000 years old and the universe much younger despite the knowledge of light speed and the time it takes images to travel vast distances.


It is doubtful our relationship with money, politics and budgets will change in the foreseeable future. Fights in the echo chamber also known as "The Hill" will never get to a place that moves us forward as a nation, almost guaranteeing a stratified educational system that soon will not be able to produce talent beyond the usual privileged suspects, nor compete on a global level. We are soundbite-driven and jingoistic to inanity, fiddling as a modern Rome burns.

 

Unlike Star Trek, we won't evolve to just do science research for the greater good.

Such fantasies will be the providence of poets...and Trekkies.

The Pendulum and Dimensions...

Discover Magazine

While most of us take gravity for granted, physicists have a big problem with it. Their beef: As forces go, gravity is implausibly feeble. (Try asking a physicist why a kitchen magnet can pick up a paper clip even though the gravitational force of the entire Earth is pulling the clip down.) In 1999 University of Washington physicist Eric Adelberger heard a lecturer offer an intriguing explanation: Perhaps gravity only appears weak, because it operates in additional spatial dimensions beyond length, width, and height. These extra dimensions would be imperceptible in our macro world but might have a detectable influence on gravity at scales of less than the width of a hair.

Well done, Gabby! Smiley


LONDON (AP) — Make it a pair of Olympic gymnastics gold medals for Gabby Douglas, who added the all-around title Thursday to the one she won with the U.S. team two nights ago at the London Games.



Douglas became the third straight American to win gymnastics’ biggest prize, taking the lead on the first event Thursday and never really letting anyone else get close. She finished with a score of 62.232, less than three-tenths ahead of Viktoria Komova of Russia. Aliya Mustafina won the bronze.



I wanted to seize the moment,” Douglas said. “It hasn’t sunk in yet. Team finals hasn’t sunk in yet. But it will.”



Douglas brought the house down with her energetic floor routine, and U.S. teammates Jordyn Wieber, McKayla Maroney and Kyla Ross jumped to their feet and cheered when she finished. Douglas flashed a smile and coach Liang Chow lifted her off the podium.
