Mankind Is Shortening The Universe’s Life

November 26, 2007

Forget about the threat that mankind poses to the Earth: our very ability to study the heavens may have shortened the inferred lifetime of the cosmos. Over the past few years, cosmologists have taken this powerful theory of what happens at the level of subatomic particles and tried to extend it to understand the universe, since it began in the subatomic realm during the Big Bang. But there is an odd feature of the theory that philosophers and scientists still argue about. In a nutshell, the theory suggests that quantum systems can exist in many different physical configurations at the same time. By observing the system, however, we may pick out one single ‘quantum state’, and therefore force the system to change its configuration.

Surfer dude stuns physicists with theory of everything

November 26, 2007

An impoverished surfer has drawn up a new theory of the universe, seen by some as the Holy Grail of physics, which has received rave reviews from scientists. Garrett Lisi, 39, has a doctorate but no university affiliation and spends most of the year surfing in Hawaii, where he has also been a hiking guide and bridge builder (when he slept in a jungle yurt). Although the work of 39 year old Garrett Lisi still has a way to go to convince the establishment, let alone match the achievements of Albert Einstein, the two do have one thing in common: Einstein also began his great adventure in theoretical physics while outside the mainstream scientific establishment, working as a patent officer, though failed to achieve the Holy Grail, an overarching explanation to unite all the particles and forces of the cosmos. Lisi’s inspiration lies in the most elegant and intricate shape known to mathematics, called E8 – a complex, eight-dimensional mathematical pattern with 248 points first found in 1887, but only fully understood by mathematicians this year after workings, that, if written out in tiny print, would cover an area the size of Manhattan.

Android

November 13, 2007


There is no Google Phone. As we wrote a while back, Google is not building a phone. Instead, the company
has teamed up with others in the wireless industry to create an open-source operating system, as well as other services, for mobile phones. Other companies, including Motorola, LG and Samsung, are expected to build phones based on this software. While the project is called Android, everyone keeps calling it the GPhone or Google Phone. For those curious about what the Android phones will look like, Google today has posted a couple of demos of their user interface and some applications. Remember these are demos, and no phones based on this software will be available for another eight months or so. But the demos are pretty slick, and they point to a class of phones that have the look and feel of the iPhone, with a touch-sensitive surface that allows users to scroll through Web pages by sliding a finger on the screen.

PS3 & Folding@Home Set World Record

November 13, 2007

Sony’s assistance to the Folding@Home project via PlayStation 3 resulted in reaching the milestone of a petaFLOP of computation power. This is a lot of power, roughly equal to every human on planet earth doing 75,000 math equations in their head at once. I have trouble doing more than one, so clearly we would need more manpower for this task. We knew it was a lot of computing, but perhaps didn’t know that it’s a record-setter. Sony Computer Entertainment has announced the September 16 milestone has been recorded to Guinness World Records as the most powerful distributed computing network in existence.
