JERUSALEM (AP) — When Israeli scientist Dan Shechtman claimed to have stumbled upon a new crystalline chemical structure that seemed to violate the laws of nature, colleagues mocked him, insulted him and exiled him from his research group.After years in the scientific wilderness, though, he was proved right. And on Wednesday, he received the ultimate vindication: the Nobel Prize in chemistry.
"A good scientist is a humble and listening scientist and not one that is sure 100 percent in what he read in the textbooks," Shechtman said.
Quasiperiodical structures had been known well before the 20th-century. For example, tiles in a medieval Islamic mosque in Isfahan, Iran, are arranged in a quasicrystalline pattern. In 1961, Hao Wang asked the question of whether determining if a set of tiles admits a tiling of the plane is an algorithmically unsolvable problem or not. He conjectured that it is solvable, relying on the hypothesis that any set of tiles which can tile the plane can do it periodically (hence it would suffice to try to tile bigger and bigger patterns until obtaining one that tiles periodically). But his student, Robert Berger, constructed two years later a set of some 20,000 square tiles (now called Wang tiles) which can tile the plane but not in a periodic fashion.

Out of Three Dimensional world
(Reuters) - An international team of scientists said on Thursday they had recorded sub-atomic particles traveling faster than light -- a finding that could overturn one of Einstein's long-accepted fundamental laws of the universe. more...

Bob Lutz, the former Vice Chairman of General Motors, is the most famous also-ran in the auto business. In the course of his 47-year rampage through the industry, he's been within swiping range of the brass ring at Ford, BMW, Chrysler and, most recently, GM, but he's never landed the top gig. It's because he "made the cars too well," he says. It might also have something to do with the fact that Maximum Bob, who could double as a character on Mad Men, is less an éminence grise than a pithy self-promoter who has a tendency to go off corporate message. That said, his new book, Car Guys vs. Bean Counters: The Battle for the Soul of American Business, has a message worth hearing. To get the U.S. economy growing again, Lutz says, we need to fire the M.B.A.s and let engineers run the show.

Same like VoIP Leaner and Live TV is following the same destiny. There are people in technical community think that ABR can solve their issues for transporting Live/Leaner TV over the Internet. In my opinion ABR is not going to scale for Live events, only network based replication (multicast) can serve 111 million supper bowl (2011) viewers.

The DECE alliance has set up an UltraViolet platform for film lovers to create free accounts in the Internet "cloud" where versions of movies they buy in DVD or digital formats are stored in online “lockers.”
"If you buy a movie, it comes with a copy in the cloud," Warner Brothers Digital Distribution president Thomas Gewecke said during a DECE panel discussion at the Consumer Electronics Show that ends Sunday in Las Vegas.
