Science News: Nanoguitar
Photo by D. Carr and H. Craighead, Cornell. The world's smallest guitar is 10 micrometers long -- about the size of a single cell -- with six strings each about 50 nanometers, or 100 atoms, wide. The world's smallest guitar -- carved out of crystalline silicon and no larger than a single cell -- has been made at Cornell University to demonstrate a new technology that could have a variety of uses in fiber optics, displays, sensors and electronics. The "nanoguitar" -- made for fun to illustrate the technology -- is just one of several structures that Cornell researchers believe are the world's smallest silicon mechanical devices. "We have a new technology for building the smallest mechanical devices," said Harold G. The guitar has six strings, each string about 50 nanometers wide, the width of about 100 atoms.

Free Classic AudioBooks. Digital narration for the 21st Century 62 Miles Beneath the Sea! Deepest Ocean in the Solar System Discovered on Jupiter's Europa The deepest ocean on Earth is the Pacific Ocean's Marianas Trench, which reaches a depth of 6.8 miles awesomely trumped by the depth of the ocean on the Jupiter's moon, Europa, which some measurements put at 62 miles. That's deep! Although Europa is covered in a thick crust of scarred and cross-hatched ice, measurements made by NASA's Galileo spacecraft and other probes strongly suggest that a liquid ocean lies beneath that surface. The interior is warmed, researchers believe, by the tidal stresses exerted on Europa by Jupiter and several other large moons, as well as by radioactivity. Most scientists believe that the subEuropan seas are locked under tens of kilometers of ice. Heat is then conducted from the warm core by bulk convective motion of ice - huge chunks of frozen material literally carrying the heat away with them as they move up through the icy layer, shuffling and refreezing as they dump heat into space.

News ::: Columbia Engineers Prove Graphene is Strongest Material July 21, 2008 Columbia Engineers Prove Graphene is the Strongest Material Research scientists at Columbia University’s Fu Foundation School of Engineering and Applied Science have achieved a breakthrough by proving that the carbon material graphene is the strongest material ever measured. Graphene holds great promise for the development of nano-scale devices and equipment. Until now, graphene’s estimated strength, elasticity and breaking point were based on complex computer modeling theories. “Our team sidestepped the size issue by creating samples small enough to be defect-free,” said Columbia Professor Jeffrey Kysar. The studies were conducted by postdoctoral researcher Changgu Lee and graduate student Xiaoding Wei, in the research groups of mechanical engineering professors Kysar and James Hone. “Our research establishes graphene as the strongest material ever measured, some 200 times stronger than structural steel,” Hone said.

US economics: One big Ponzi scheme Thank you, Bernie, for breaking your silence - even if you are still clinging to that cover-up mode you adopted since you took the entirety of the blame for your crimes. What is clear is that ripping off the rich is punished far more severely than ripping off the poor. The lengthy sentence you were given spared countless other greedsters and goniffs from facing the music - what music there is. In an interview - with a reporter from The New York Times who is writing a book to cash in on a man who has already cashed out - we learn, in the vaguest terms, that Mr M believes the banks he did his crooked business with "should have known" his figures did not figure. Keeping with the deceit that has served him well over the years, he names no names. That said, how right he may be. For years, he went undetected by business journalists, who knew - or should have known - what he was up to. Do not believe all you read At the same time, the people investigating Madoff are making a small fortune.

First Quantum Effects Seen in Visible Object Science has proved contradiction. Unless, of course, we know that contradiction is impossible, and that the law of non-contradiction was used in the process of "proving" contradiction, making it a self-defeating argument. Now, any rational person will know that nothing can be and not be at the same time, so this whole thing is absurd on its face, unless you take it to mean both are happening in some kind of figurative, unreal sense, in which case the article is luridly, and I suspect purposefully, misleading. Take away the breaking of the law of non-contradiction. Even then this is totally flawed and absolutely incorrect. There are no such things as "probabilistic rules" in reality. These things are unknowable until they actually occur, yet follow laws of probability? Just thought I would be polemical and challenge the smug consensus here.

I, For One, Welcome Our New Computer Overlords Last night, IBM’s Watson computer won the final round of the three-day Man V. Machine Jeopardy! competition. At the beginning of the show, the humans were fierce, proving that they could buzz in faster than Watson, even though the machine knew the answer. But by the time Final Jeopardy came around, Watson was ahead and was able to decipher the clue: “William Wilkinson’s ‘an account of the principalities of Wallachia and Moldavia’ inspired this authors’s most famous novel” and provide the question, “Who is Bram Stoker?” Both human competitors, Ken Jennings and Brad Rutter, got it correct as well. Rutter: $21,600Jennings: $24,000Watson: $77,147 But although Watson won the competition, humans still prevailed. On Jeopardy! In this video from IBM, project researchers describe how a computer system like Watson could be capable of reading an unlimited number of documents, understanding the information and completely retaining it. I think Watson is agreat achievement of our time.

15 Words You Won't Believe They Added to the Dictionary The Oxford English Dictionary is constantly updating, adding new words to reflect the vibrant changes in language and culture. Of course, that also means that as said culture spirals toward a frightening and retarded oblivion, the good people at Oxford have to be there to chronicle it. Here are some recent additions that make us fear for our future. n. In the fiction of J.K. Rowling: a person who possesses no magical powers. The people at the Oxford English Dictionary acknowledge that the work of an author entering the dictionary is rare, but the use of "muggle" had become so widespread they had to include it, ensuring that the future will remember us for standing in line at Borders in wizard costumes. Wait, does this mean if we invent a new word right now they'll be forced to include it in a few years, as long as enough readers use it? n. There already is a word for when a group of people blame someone for a mistake. "We're so witty! n. n. What the fuck is that? n. n. n. v.
