An anonymous reader writes "At a symposium at the Dutch Spinoza-instituut on 8 December, 2009, string theorist Erik Verlinde introduced a theory that derives Newton's classical mechanics. In his theory, gravity exists because of a difference in concentration of information in the empty space between two masses and its surroundings. He does not consider gravity as fundamental, but as an emergent phenomenon that arises from a deeper microscopic reality. A relativistic extension of his argument leads directly to Einstein's equations." Here are two blog entries discussing Verlinde's proposal in somewhat more accessible terms.
Update: 01/12 04:48 GMT by KD : Dr. Verlinde has put up a blog post explaining in simpler terms the logic of the gravity from entropy paper. He introduces it with: "Because the logic of the paper is being misrepresented in some reports, I add here some clarifications."

EagleHasLanded writes "Russian mathematician Grigory Perelman doesn't talk to journalists. Actually, he doesn't talk to anyone anymore. So we'll have to settle for insights via his biographer, Masha Gessen, who, strangely enough, has never talked to him either. But she has spoken with just about everyone who has ever had any significant interaction with Perelman, and the result is the book Perfect Rigor, which more than adequately explains why Perelman has gone into self-imposed exile, and why he probably won't collect the million dollars he won by solving the Poincare Conjecture."

Barack Obama has just been awarded the Nobel Peace Prize. The BBC opines: "In awarding President Obama the Nobel Peace Prize, the Norwegian committee is honoring his intentions more than his achievements. After all he has been in office only just over eight months and he will presumably hope to serve eight years, so it is very early in his term to get this award. ... The committee does not make any secret of its approach. It states that he is being given the prize 'for his extraordinary efforts to strengthen international diplomacy and co-operation between peoples.' This is of course an implied criticism of former US president George W Bush and the neo-conservatives, who were often accused of trying to change the world in their image." The Washington Post collects more reactions from around the world.

destinyland writes "How much would you use technology to change yourself if humanity faced extinction? In this interview, the two creators behind Eclipse Phase explain their bizarre role-playing game, which 'expands the transhuman conversation.' All the characters can be identical clones, and when you switch bodies, it affects your core characteristics while damaging your sanity. But its spookiest concept is close to reality today: the idea of universal surveillance in which 'everything is networked and equipped with sensors and all meshed together.'"

CWmike writes "The Free Software Foundation today launched a campaign against Microsoft Corp.'s upcoming Windows 7 operating system, calling it 'treacherous computing' that stealthily takes away rights from users. At the Web site Windows7Sins.org, the Boston-based FSF lists the seven 'sins' that proprietary software such as Windows 7 commits against computer users. They include: Poisoning education, locking in users, abusing standards such as OpenDocument Format (ODF), leveraging monopolistic behavior, threatening user security, enforcing Digital Rights Management (DRM) at the request of entertainment companies concerned about movie and music piracy, and invading privacy. 'Windows, for some time now, has really been a DRM platform, restricting you from making copies of digital files,' said executive director Peter Brown. And if Microsoft's Trusted Computing technology were fully implemented the way the company would like, the vendor would have 'malicious and really complete control over your computer.'"
