Submission + - Moebius strip riddle solved at last (abc.net.au) 2

BigLug writes: "In a study to appear in Nature Materials, two experts in non-linear dynamics, Gert van der Heijden and Eugene Starostin of University College London, resolve the Moebius Strip algebraically.

From the ABC (Australia):



What determines the strip's shape is its differing areas of "energy density," they say.

"Energy density" means the stored, elastic energy that is contained in the strip as a result of the folding. Places where the strip is most bent have the highest energy density; conversely, places that are flat and unstressed by a fold have the least energy density.

The Wii - Is the Magic Gone? 492

Computer And Video Games asks the tough question: is the Wii's magic gone? After the flurry of excitement around the launch, lackluster ports and a persistent inability for Nintendo to keep units on the shelves has made it hard for gamers to sustain their enthusiasm for the system. It doesn't help that most of the good games slated for this year won't be out for months. In some cases, there's doubt they'll even make it out this year: Reggie Fils-Aime appears to be backpedaling on Metroid Prime 3 by Christmas, which would be a shame. GigaGamez has additional commentary. Are you still as excited about the Wii as you were when it launched?

Dell Laptop Burns House Down 405

Nuclear Elephant writes "The Consumerist is running a story about a house burned down by a Dell laptop. 'My 130-year-old former farm house was engulfed in flames, with thick dark smoke pouring out of the windows and roof... Hours later, after investigation the fire marshal investigator took me aside asked me if I had a laptop computer. Yes — I told him I had a Dell Inspiron 1200.' It was determined that the laptop, battery, or cord malfunctioned after its owner left for work, leaving the fire to spread through the entire house. All attempts to contact Dell have failed. 'I have tried to call Dell to at least notify them of my problems, but each time I have called I get transferred into an endless loop of "Joe" or "Alan" all speaking a delectable version of English I presume emanates from Bangalore. I have been outright hung up on each time I get someone who speaks a reasonable version of English, or sounds like they might be in charge of something. Promises of call backs have gone, of course, unreturned.'"

MS Seeks Patent For Repossessing School Computers 299

theodp writes "Microsoft has applied for a patent for 'securely providing advertising subsidized computer usage.' The application describes how face-recognition webcams and CAPTCHAs can be used in schools to ensure that computer users are paying attention to ads, and the recourse of 'disabling or even repossessing the computer' if they are not."
