Ouch!...

Full report here

At a panel discussion at the conference, a number of scientists and science policymakers said these poll figures reveal a startling degree of public skepticism toward the United States's ability to compete globally in scientific research. They blamed the public's perception of the United States as a dwindling science powerhouse on a lack of long-term thinking by lawmakers tasked with funding national science endeavors. While China and the European Union have taken steps to increase their research budgets, the United States more recently has struggled to keep its research budget from declining...

 
No sooner than yesterday's posting. I thought to scale back my comments. I'm glad I didn't!
 
To be fair and elucidate: the chart above and a the link below the picture seems at first glance we're OK having the proverbial "biggest piece of the pie." Adding all the other parts, it merely says collectively there is skepticism regarding our collective ability to do anything of significance or visionary leadership. A collective sigh; a national shoulder-shrug.
 
Cosmological Age, Evolution, Global Warming: we've become a sound-bite culture where journalism is meaningless, coreligionist rather than reasoned or rational, more concerned with scoring political points than solving critical problems: and jingoism is not patriotism! It makes Octavia Butler's "Parable of the Sower" and "Parable of the Talents" almost prophetic.
 
Prophecy, nor predictive models have to be destiny: it only occurs when either go unheeded.

No Scientists Need Apply?...


John Paulos is a Mathematics Professor at Temple University. Writing in the New York Times:

I’ve visited Singapore a few times in recent years and been impressed with its wealth and modernity. I was also quite aware of its world-leading programs in mathematics education and naturally noted that one of the candidates for president was Tony Tan, who has a Ph.D. in applied mathematics. Tan won the very close election and joined the government of Prime Minister Lee Hsien Loong, who also has a degree in mathematics.

 

China has even more scientists in key positions in the government. President Hu Jintao was trained as a hydraulic engineer and Premier Wen Jiabao as a geomechanical engineer. In fact, eight out of the nine top government officials in China have scientific backgrounds. There is a scattering of scientist-politicians in high government positions in other countries as well. German Chancellor Angela Merkel has a doctorate in physical chemistry, and, going back a bit, Margaret Thatcher earned a degree in chemistry.

I personally think it's a matter of motivation.
Usually, politics is not seen as a "STEM Career," so many don't even think to pursue such a path beyond the lab/fab. Dealing with a circuit/test tube/sample is far simpler than saying the right sound-bite-tested phrase for the cameras. It's quieter than a political rally.

It's also my observation that politicans have "emotional intelligence," meaning they can "move a crowd," a skill they need if they want to maintain a job. A skill unnecessary in a laboratory. Tech types tend to be self-motivated.

 
From Wikipedia: The term technocracy was originally used to designate the application of the scientific method to solving social problems, in counter distinction to the traditional economic, political or philosophic approaches. According to the proponents of this concept, the role of money and economic values, political opinions, and moralistic control mechanisms would be eliminated altogether if and when this form of social control should ever be implemented in a continental area endowed with enough natural resources, technically trained personnel, and installed industrial equipment so as to allow for the production and distribution of physical goods and services to all continental citizens in an amount exceeding the individuals' physical ability to consume.

 

This would, unfortunately create a new "class" of being that only specialized knowledge would allow the ascendancy to the governing body. Since it would only require a select few, much as our current system of governance, it would become quite evident that the shift of power would favor one group (s) over others. The world does not work like Star Trek, or Vulcan. Our baser instincts would prevail. (Besides, it ultimately didn't work so well on the fictional home of Superman - they, er... blew up.) Smiley

 

However, the current pandering to focus groups and "the base" needs to cease. Our leaders need SOME appreciation of science for clear decision-making, else they will model an anti-intellectualism that will soon become the "new normal," one we will not recover from...for maybe a generation.

ET Don't Phone?...

OK: It's kind of a rant, but hopefully a thought-provoking one.

Screeneddotcom



Star Trek made us fawn over Vulcans; loath Klingons (who in a wierd Worf way, turned out to be cool), and Romulans (not-so-much).

ET gave us the cute beneficent alien, we didn't get a whole lot of tech from him/her, but a good feeling after seeing him/her with a young, screaming Drew Barrymore; we rooted for ET when we thought its life force left.

SETI has three links on this blog page: each starts with, er "SETI" on "Cool Physics Links." However, with the current political climate of "other-ness," my predictions are gloomy, but succinct:

- gun sales would increase along with survivalists and militias;

- a new invective -- like "Slag" in Alien Nation -- would be invented;

- the new-new concern would be inter species marriages;

- Ragnorok, End-Time, Mayan Prophecies et al would become prominent immediately.

I'm watching a lot of episodes on Science Channel on the subject: "Are We Alone"; "Alien Encounters." It's in the nerd Zeitgeist (a very small fraction of said Zeitgeist, mind you).

An interesting paper is making its way across the net asking if "first contact" will help or harm humanity: Acta Astronautica. I'm reminded of the Twilight Zone episode: "To Serve Man."

I think sadly, we only have ourselves as reference, and how we evolved as the top of the predatory scale, similar to H.G. Wells' recollection of Britain's foray into Australia inspiring War of the Worlds. A feeling of universal reciprocity; "karma" that we would reap the whirlwind: what we've collectively sown in the winds of time...with one another.

Quantum Cognition...

Quantum Biology

The aim of [quantum cognition] is to use quantum theory to develop radically new models of a variety of cognitive phenomena ranging from human memory to decision making. Although speculative, this research is gaining momentum. For instance, later this year, the highly regarded Journal of Mathematical Psychology will publish a special issue of quantum models of cognition. In addition, quantum cognition is a prominent theme within the Quantum Interaction Symposia, which provide a forum for a growing body of researchers applying quantum theory to non-quantum domains.

I recall a reporter interviewing me for a fitness magazine (I owned a martial arts studio at the time) describing themselves as "mental." Explains a lot...

This kind of lends to either a step towards quantum computing, or the "woo woo" physics I blogged on earlier. Although: Paris in June sounds nice (see Symposia link above). Smiley

Graphene Battery...



Researchers at Hong Kong Polytechnic University claim to have invented a new kind of graphene-based "battery" that runs solely on ambient heat. The device is said to capture the thermal energy of ions in a solution and convert it into electricity. The results are in the process of being peer reviewed, but if confirmed, such a device might find use in a range of applications, including powering artificial organs from body heat, generating renewable energy and powering electronics.

 

Hope...for my laptop!Smiley

SST...



Since its launch in July 1986, Semiconductor Science and Technology (SST) has grown to become one of the leading international journals on semiconductor physics. This year marks the 25th anniversary and to celebrate, we highlight some of the top contributions in this time and chart the progress of this effervescent field.

 

Introduced to fulfill the needs of the semiconductor physics community whose research was becoming more applied, SST has gone from strength-to-strength over the years under the leadership of its eminent Editors-in-Chief, Tony Stradling, Erich Gornik, Gareth Parry and Laurens Molenkamp.


With the field of semiconductor physics continuing to explode with exciting new research areas—driven by talented researchers—the future of SST looks very bright.

This is something I enjoyed reading at the technical library in Austin in the analog/magazine days.

This site has PDF reports you can download and read at your leisure. It's a good resource for your curiosity, and how/where you can see contributing to the acumen and intellectual conversation if you work/publish/study in the field.

"Heat" Pump...

LED

light-emitting diode (LED) that emits more light energy than it consumes in electrical energy has been unveiled by researchers in the US. The device – which has a conventional efficiency of greater than 200% – behaves as a kind of optical heat pump that converts lattice vibrations into infrared photons, cooling its surroundings in the process. The possibility of such a device was first predicted in 1957, but a practical version had proved impossible to create until now. Potential applications of the phenomenon include energy-efficient lighting and cryogenic refrigeration.

KSTAR...

National Fusion Research Institute Image

KSTAR (Korea Superconducting Tokamak Advanced Research), the most recently built among global tokamak facilities, is a superconducting tokamak facility developed in Korea with the purposes of 'long-term fusion plasma operation' and 'acquisition of controlling technology,' which are tasks that must be solved in order to commercialize fusion energy. To be operated as an international joint research facility for fusion, KSTAR is expected to take the role of performing preceding research using pilot devices during the construction phase of ITER and the role as a satellite during the operation phase of ITER as the first tokamak facility in the world developed using the same superconducting material as ITER, Nb3Sn, and as a hub for the global fusion research.

The primary element for fusion is Deuterium, found in sea water.

It could literally power the planet for millions of years, relieve our global dependency on fossil fuels.

The engineering problem of all time: create a sun on Earth, and control it.

Whenever you want me, I'll be there
Whenever you need me, I'll be there
I'll be around

I, knew just what to say
Now I found out today
That all the words had slipped away, but I know

There's always a chance
A tiny spark remains, yeah
And sparks turn into flames
And love can burn once again, but I know you know

Whenever you call me, I'll be there
Whenever you want me, I'll be there
Whenever you need me, I'll be there
I'll be around...yeah

Whenever you call me, I'll be there
Whenever you want me, I'll be there
Even if I have to call, I'll be there
I'll be around

Just call me at home, I'll be there
I'll never leave you alone, I'll be there
Just call out your name you know I know you know
I'll be around

TEC...

Topological qubits imagined as lanterns

An international team of physicists is the first to implement in the lab an important "error correction" technique that could play a vital role in the development of practical quantum computers. Known as topological error correction (TEC), the technique is based on "clusters" that each contain eight highly entangled photons. These clusters are useful for this purpose because a measurement on one photon does not destroy the entire entangled state.

 

The multiparticle cluster state at the centre of the current work was first proposed in 2001 by Robert Raussendorf and Hans Briegel, who were then at the University of Munich. Now at the University of British Columbia in Canada, Raussendorf is also involved in this latest research. Such a cluster could be used to perform "one-way" quantum computing, in which the states of individual particles are measured in a specific sequence so that the quantum state of the remaining particles gives the result of the computation.

"Spooky action at a distance" - Einstein

In the past 20 years scientists have shown that single molecules can be detected and single photons can be generated. However, excitation of a molecule with a photon had remained elusive because the probability that a molecule sees and absorbs a photon is very small. As a result, billions of photons per second are usually impinged on a molecule to obtain a signal from it. One common way to get around this difficulty in atomic physics has been to build a cavity around the atom so that a photon remains trapped for long enough times to yield a favorable interaction probability. Scientists at ETH Zürich and Max Planck Institute for the Science of Light in Erlangen have now shown that one can even interact a flying photon with a single molecule.

 

The results of the study published in Physical Review Letters provide the first example of long-distance communication between two quantum optical antennas in analogy to the 19th century experiments of Hertz and Marconi with radio antennas. In those early efforts, dipolar oscillators were used as transmitting and receiving antennas. In the current experiment, two single molecules mimic that scenario at optical frequencies and via a nonclassical optical channel, namely a single-photon stream. This opens many doors for further exciting experiments in which single photons act as carriers of quantum information to be processed by single emitters.

Physics Apps and Caveats...


It's simply called the New Apple iPad. According to Technabob.com, it uses "a new chip called the A5X, a quad-core CPU/GPU designed to run significantly faster than the existing A5 CPU." That means definition, on the order of "2048×1536, or a total of 3.1 million pixels at a density of 264 pixels per inch."

Be that as it may: Technology Review lists the 800-lb Caveat Emptor in the room - gigabyte downloads.

A Change in BMI?...


Dr Ian Robinson with the NPL watt balance

NPL (National Physical Laboratory) has produced technology capable of accurate measurements of Planck's constant, which is a significant step towards changing the international definition of the kilogram – currently based on a lump of platinum-iridium metal kept in Paris, France.

I doubt it will change our BMI, but "hope springs eternal"...

1st Single Atom Transistor - University of New South Wales

...8 years earlier than predicted! Smiley

Physicists at Purdue University and the University of New South Wales have built a transistor from a single atom of phosphorous precisely placed on a bed of silicon, taking another step towards the holy grail of tech research: the quantum computer.

 

Revealed on Sunday in the academic journal Nature Nanotechnology, the research is part of a decade-long effort at the University of New South Wales to deliver a quantum computer — a machine that would use the seemingly magical properties of very small particles to instantly perform calculations beyond the scope of today’s classical computers.

 

...the New South Wales team — lead by professor Michelle Simmons — advanced the cause by demonstrating that Ohm’s Law of electrical resistivity extends to the world of very small particles, and now, together with Gerhard Klimeck and his team at Purdue, they’ve made a more significant breakthrough by placing a single-atom transistor exactly where they want to place it.

Beyond Bird's Eye View...


Oh! I have slipped the surly bonds of earth
And danced the skies on laughter-silvered wings;

Sunward I've climbed, and joined the tumbling mirth
Of sun-split clouds - and done a hundred things

You have not dreamed of - wheeled and soared and swung
High in the sunlit silence. Hov'ring there

I've chased the shouting wind along, and flung
My eager craft through footless halls of air.

Up, up the long delirious, burning blue,
I've topped the windswept heights with easy grace

Where never lark, or even eagle flew -
And, while with silent lifting mind I've trod

The high untresspassed sanctity of space,
Put out my hand and touched the face of God.

Conundrum...

Todd's Quantum Intro

I recently gave a lecture, screened on the BBC, about quantum theory, in which I pointed out that “everything is connected to everything else”. This is literally true if quantum theory as currently understood is not augmented by new physics. This means that the subatomic constituents of your body are constantly shifting, albeit absolutely imperceptibly, in response to events happening an arbitrarily large distance away; for the sake of argument, let’s say on the other side of the Universe.

 

This statement received some criticism in scientific circles. Not because it’s wrong, because it isn’t; without this behavior, we wouldn’t be able to explain the bonds that hold molecules together. The problem is that it sounds like woo woo, and quantum theory attracts woo-woo merde-merchants like the pronouncements of New Age mystics attract flies – metaphorically speaking.


This is an article that appears in the Wall Street Journal (link below) by Professor Brian Cox on how Quantum Mechanics can be so misunderstood. Of course, at the end of the article is the obligatory Amazon link to the book on the subject he co-authored.

I've run into a few physicists - in-person and online, that take a dim view of popular books on physics.

Largely, because science is a field of inquiry, so value is given to how you pursue said inquiry, and how many people reference your research in their inquiries (in the right technical journals by all the right people). Kind of incestuous, but essentially how it works. Nobel Prizes in the sciences are awarded for a lifetime of plodding along (in the right direction), and peer review.

Oddly, the conundrum is that popular books on science tend to sell better than free downloads on physics arXiv; also science fiction short stories that sometimes birth movies that nerds and graduate students motivated by common cause (and hormones) go pay money to see.

I agree that inspiring the wonder of science is what is needed now. We've become consumers and not anticipant producers. I've been criticized on this point before, that education is not so "utilitarian."

Science, however is primarily a way of thinking, of organizing one's thoughts around The Scientific Method towards problem-solving. Plays, opera, poetry, sermons, concerts: these things are also enjoyed by scientists as welcome respite from the lab, a break from the questions raised in the lab/fab to tackle problems refreshed; anew.

However, as a society, we are motivated by the entertainment-industrial-complex: all must be show biz - education, science, religious life, engineering, politics, governance or, it is not valued. "Walking Encyclopedia" is replaced by "Walking Google" in the lexicon, answers not instant ≠ value.

Pity [not] the Billionaire: but the researcher striving to strenghten her/his signal; in so much noise.
