Sonochemical Observatory

Camera Lucida is an interactive “sonic observatory” that converts sound waves into light by means of a phenomenon called sonoluminescence.

The continually evolving light sculpture allows one to see sound moving through space ? at the meeting point of acoustics and optics. Using sonoluminescence, sound waves are directly converted into light inside a glass chamber filled with gas-infused liquid. After adapting to the darkness surrounding the installation, one can gradually perceive the highly detailed shapes and movements of multiple sound sources.

So far, the only way to view sonoluminescence was in a highly specialized sonochemical laboratory. Camera Lucida presents the first opportunity for people outside the scientific community to experience this rare phenomenon.

Clean buildings

Scientists are fighting smog by developing “smart” building materials that clean the air with a little help from the elements.

Using technology already available for self-cleaning windows and bathroom tiles, they hope to paint up cities with materials that dissolve and wash away pollutants when exposed to sun and rain. “We want to construct concrete walls that break down vehicle exhausts in road tunnels,” said Karin Pettersson, from Swedish construction giant Skanska. “It is also possible to make pavings that clean the air in cities.”

The project aims at developing catalytic cement and concrete products coated with titanium dioxide, a compound that can become highly reactive when exposed to UV light. UV rays hitting the titanium dioxide trigger a catalytic reaction that destroys the molecules of pollutants. The reaction also prevents bacteria and dirt from sticking to a surface, making them easily removed by a splash of water or rain.

LORDS OF ACID: How the Brotherhood of Eternal Love Became OC?s Hippie Mafia

sm44lede_timlearyposter.jpg
‘In the midst of that throbbing mass of passionately entwined bodies, Thumper set foot on a path that would take him into the arms of the Brotherhood of Eternal Love, a legally registered nonprofit religious institution centered on Mystic Arts World, a head shop in downtown Laguna Beach. The church?s figurehead and high priest was Timothy Leary, a world-famous former Harvard psychology professor turned proselytizer of psychedelic drugs. Leary and the Brotherhood preached spiritual awakening through Buddhist meditation and drug experimentation.’

“Leary?s mantra?Tune in, turn on, drop out?had already led countless disaffected middle-class kids to quit their jobs or classes, head to California and drop acid. The Brotherhood?s bible was Leary?s Psychedelic Prayers, his idiosyncratic translation of the Tibetan Book of the Dead. Mystic Arts sold copies of Leary?s book, along with incense, candles and imported countercultural paraphernalia. Behind a bamboo-covered wall, church members gathered in a secret meditation room decorated with a massive Taxonomic Mandala, a technicolor spiral depicting the evolution of life, from primal ooze to Homo sapiens.”

We Must Address the Root Causes of this Terror by Imran Khan

The terrorist attacks have nothing to do with religious faith and everything to do with genuine injustices. Until the US addresses the root causes and its own double standards, the bombings will increase.

As a Pakistani, it has been a bad week to be in London. Not only could one’s relations or friends have been blown up, but those who committed those hideous crimes justified them in the name of Islam. Even worse for me was the news that three of the four terrorists had been to Pakistan. But neither Islam nor Pakistan has anything to do with these atrocities. Nowhere does the Koran justify attacks on innocent people. Pakistan is being blamed for fostering terrorists, yet Pakistan has been a victim for the past 15 years.

Some history is in order…

Why the Culture Can’t be Jammed…

Canadian authors Joseph Heath and Andrew Potter in 2004 released a book called The Rebel Sell: Why the Culture Can’t be Jammed, criticizing culture jamming (a form of activism and a resistance movement to the perceived hegemony of popular culture, based on the ideas of “guerrilla communication” and the “detournement” of popular icons and ideas) as not only ineffective, but encouraging the very consumerism it seeks to quell. (The U.S. release of the book is called Nation of Rebels: Why Counterculture Became Consumer Culture). In a wider critique of the underlying theory of counterculture largely inspired by the writing of Thomas Frank, Heath and Potter note that the capitalist system thrives not on conformity—as so many ‘culture jammers’ believe—but rather on individualism and a quest for distinction. Thus, culture jamming cannot bring down “the system” or “The Man,” because “the system” doesn’t care if you do things differently from others, and, in fact, is more than happy to accommodate you by selling you ‘non-conformist’ goods.

The book goes on to explain that consumerism comes largely from competitive consumption in an effort for distinction, and ‘rebellion’ is an excellent path to distinction. Since most goods depend on exclusivity for their value, especially goods which are said to decry mainstream life, a purchasing ‘arms race’ is created whenever others begin to follow the same tendencies: if you lag, you become mainstream. Not surprisingly, then, the image of rebelliousness or non-conformity has long been a selling point for many products, especially those that begin as ‘alternative’ products. Far from being ‘subversive,’ encouraging the purchase of such products (such as Adbusters’ line of running shoes) does nothing more than turn them into ‘mainstream’ ones. This tendency is very easy to observe in music, for example.

Novel Solar Tech Could Lead to 40% Drop In Solar Power Price

pyron.jpg
When scanning for emerging technologies, there are a couple of useful rules-of-thumb: if something looks too good to be true, it probably is; if someone claims everyone is ignoring their brilliant idea, it’s probably not as brilliant as they think. It stands to reason, then, that if the brilliant idea that everyone is ignoring happens to provide benefits that are too good to be true, it’s time to nod, smile, and move along as swiftly as possible.

I was prepared to do just that to this article about Pyron Solar, a San Diego-based company making a novel solar concentrator system. After all, the article spends its first third trying to draw an analogy between the Pyron Solar founders (John and Inge Laing) and Thomas Edison, particularly the early Edison that had to struggle to get people to recognize his brilliant ideas. The article then goes on to describe the Pyron system as being substantially better than anything yet produced in terms of solar: a device able to generate electricity at a cost-per-watt as low as oil or coal—and possibly lower. But then I noticed something.

They’ve actually built the thing. And it works.

Scientists discover a whole family of one-atom-thick materials, New Industrial Revolution inbound?

Scientists at The University of Manchester have discovered a new class of materials which have previously only existed in science fiction films and books. A team of British and Russian scientists led by Professor Geim have discovered a whole family of previously unknown materials, which are one atom thick and exhibit properties which scientists had never thought possible.

Not only are they ultra-thin, but depending on circumstances they can also be ultra-strong, highly-insulating or highly-conductive, offering a wide range of unique properties for space-age engineers and designers to choose from.

Professor Andre Geim said: “This discovery opens up practically infinite possibilities for applications which people have never even thought of yet. These materials are lightweight, strong and flexible, and there is a huge choice of them. This is not only about smart gadgets. Like polymers whose pervasiveness changed our everyday life forever, one-atom-thick materials could be used in a myriad of routine applications from clothing to computers.”

Two nuclear historians say U.S. nuked Japan to kick-start the cold war, not end WWII.

The US decision to drop atomic bombs on Hiroshima and Nagasaki in 1945 was meant to kick-start the Cold War rather than end the Second World War, according to two nuclear historians who say they have new evidence backing the controversial theory.

Causing a fission reaction in several kilograms of uranium and plutonium and killing over 200,000 people 60 years ago was done more to impress the Soviet Union than to cow Japan, they say. And the US President who took the decision, Harry Truman, was culpable, they add.

Personal Outsourcing

Journalist Ben Hammersley says companies aren?t the only ones who can offshore jobs – individuals can, too:

I needed a webpage built. Web designers are everywhere, and web hosting is cheap. It is just much cheaper in India. So, ?30 paid via PayPal.com to templatekingdom.com got me a website design, an hour of the designer?s time for changes, and a year?s hosting for good measure. In 24 hours, and for less than the price of a few rounds in a pub, I had a new, uniquely designed website up and running. For small businesses needing a home page, why spend hundreds of pounds on a domestic designer, when something just as good can be commissioned from designers in India or Bangladesh?

studies show that mountain dwellers live longer

People who live in mountain areas live longer than those living in lowland areas, according to research from Greece, which has the lowest death rate from heart disease of any developed country.

A study started in 1981, which tracked the cardiovascular health and death rates of 1150 inhabitants of three villages not far from Athens, collected information on risk factors, including gender, age, weight, smoking habit, blood pressure, and alcohol consumption. They used the data taken over 15 years to build up a profile of the biochemical health of the villagers; blood samples were also taken.

The Twike

twike.jpg The Twike is a lightweight (~500-800 lbs.) three-wheel, two seat vehicle. It comes in two models, and both feature electric motors able to take the car up to 130 kilometers at speeds up to 85 kilometers per hour—not quite freeway speeds, but more than enough for major roads and horoughares. Like most modern electrics, it has regenerative braking to help recharge the battery, but can be “refilled” from a standard outlet. What differentiates the two models—the Active and the Easy—is that the Active also has a pair of recumbent bicycle pedals for each passenger, allowing the driver to extend the range of the vehicle, and get a bit of exercise while at it.

Google Earth new way to view world

earth_th.jpgIt’s good to have a healthy skepticism about the claims of the hype-driven technology industry. But there are times when even a hardened skeptic has to admit to amazement at the sheer coolness of some of the things you can do on a personal computer. And one of those “wow” moments happens the first time you run a new program called Google Earth.

The program lets you view satellite and aerial photos of almost any spot on the planet. In big metropolitan areas in the U.S., Canada and Western Europe, you can zoom in on individual buildings and houses. You can overlay streets onto these urban images, as well as markers indicating restaurants, hotels and more. In other places, you can make out only towns and large geographical features, like lakes.

The program rapidly fetches the images from the Internet and visually “flies” you around the globe. The process is so fluid it feels like a Hollywood stunt. For instance, if you’re staring at a bird’s-eye view of St. Mark’s Square in Venice and you type in your address in Boston, Google Earth will zoom out till you seem high in the sky, then rapidly “fly” you west across the Atlantic into the U.S., and then stop right over your house.
