Gates Puts Feynman Lectures Online

Microsoft Chairman Bill Gates believes that if he had been able to watch physicist Richard Feynman lecture on physics in 1964 his life might have played out differently. Mr. Gates, of course, is legendary as a Harvard University dropout who went on to create the world’s most successful software firm. He has told associates that if had watched the lectures earlier in his life he might have become a physicist instead of a software entrepreneur. However, Mr. Microsoft Research announced on Wednesday that Mr. Tongue controller for the paralyzed offers greater independence.

NEW YORK (Reuters) - From fashion statement to ... wheelchair controller?

Tongue controller for the paralyzed offers greater independence

In an advance that promises to improve the lives of the more than 250,000 people in the United States who are paralyzed from the neck down, researchers announced on Wednesday that they have developed a wireless device that operates specially rigged chairs by means of a tiny titanium barbell pierced through the tongue. Merely by moving their tongues left or right across their mouths, essentially using it as a joystick, paralyzed patients have been able to move their motorized wheelchairs, as well as computer cursors. Tapping tongue against cheek, quickly or slowly, controls the chair's speed. 25 Documentaries Everybody Should Watch.

25 Documentaries Everybody Should Watch

It is a fleeting memory, a sudden remembrance of times long past, a meditation on time and culture, a touch of an emotional diary. We follow the eyes of a world traveller who makes sharp observations and tries to convey them to his friend. We never learn who they are and where they came from, and this is perhaps a subtle point the documentary wants to make. The narrator’s voice switches from Japanese to German to English to French, thereby embodying the language of the places visited.

People often confuse the two as separate and nothing could be further from the truth. Having said that, the question of morality, and the Tree of Knowledge of Good and Evil are exactly the lesson that God was teaching. Tyson eluded that we need better moral management, while God on the other hand was warning us that we do not have the capacity to do so on our own. This tree did no way mean moral ability and insight! If so, Adam and Eve wouldn´t even KNOW it was wrong to eat, thus God wouldn´t have punished them.

Phonebloks: a utopian world where smartphones are a bit more like Lego

But heck, much stranger things have happened in the world of consumer electronics, and certainly the maker and crowdfunding communities have gone a ways toward helping us rethink our devices. What about a smartphone that could score a 10 every time iFixit teared it down? Phonebloks: a utopian world where smartphones are a bit more like Lego.

See What Happens When a Squid Listens to Cypress Hill

Fascinated by the fast color-changing nature of the squid’s skin and their ability to quickly control pigmented cells called chromatophores, the folks at Backyard Brains wondered what exactly would happen if they played music to a squid. In order to satisfy their curiosity they attached a suction electrode to the squid’s fin nerve and then connected the electrode to an iPod nano as their stimulator. The results are incredible. Scientists engineer suicide bomber bacteria to kill other bacteria. In a lab in Singapore, scientists are designing and breeding suicide bombers.

If their efforts pan out, they will be applauded rather than jailed, for their targets are neither humans nor buildings. They’re bacteria. Nazanin Saeidi and Choon Kit Wong have found a new way of killing Pseudomonas aeruginosa, an opportunistic species that thrives wherever humans are weak. The Effects of Marijuana on Consciousness.

The Effects of Marijuana on Consciousness

Tart, Doubleday & Co., 1972, Chapter 22 A marijuana high usually lasts two or three hours, during which a wide range of effects may occur, varying both in intensity and quality. The usual, most noticeable effect is intensification of sensation and increased clarity of perception. Visually, colors are brighter, scenes have more depth, patterns are more evident, and figure-ground relations both more distinct and more easily reversible. : Hacking into the Human. Untitled.

New Model of the Universe Says Past Crystallizes out of the Future

Not a great deal, if you take a purely relativistic view of the universe, say George Ellis from the University of Cape Town in South Africa and Tony Rothman from Princeton University in New Jersey. The standard spacetime diagrams used in relativity accord no special status to the past, the present or the future. That’s because they assume that everything evolves from time-reversible local physics. Murphy.

Would you like to own an Airsoft gun, but can’t afford to buy one? How about making one instead using a soda bottle? Better yet, how about making a machine gun that only requires 4 cheap and commonly available parts that’s capable of firing hundreds Airsoft BBs before a reload is required? The informative video below shows you exactly how to do that for around $15. The parts you’ll need include a plastic soda bottle, a quick release air compressor adaptor, an air compressor blowgun, and a 7mm by 6-inch brake line. The other thing you will need is a compressed air supply.

Plastic-eating fungus could help deal with landfill. A team from Yale University has discovered a fungus deep in the South American rainforest that can live entirely on plastic - offering hope for new methods of waste disposal. Pestalotiopsis microspora, found in the jungles of Ecuador, can digest polyurethane - which often currently ends up in landfill and takes generations to decay. Burning polyurethane releases toxins as well as carbon dioxide; and, while it can be recycled, it frequently isn't. The fungus can live entirely on polyurethane. And, most intriguingly, the fungus can break down polyeurethane even without the presence of oxygen, meaning it could do its trick even at the bottom of a landfill site.
