Simulating Climate Change Using New Technique
2013-03-05 13:13:13

Brown University Statistical physics offers an approach to studying climate change that could dramatically reduce the time and brute-force computing that current simulation techniques require. The new approach focuses on fundamental forces that drive climate rather than on “following every little swirl” of water or air. And yes, there´s an app for that. Scientists are using ever more complex models running on ever more powerful computers to simulate the earth´s...

Sequoia Passes One Million Cores

Peter Suciu for redOrbit.com — Your Universe Online The most advanced gaming PCs rely on quad-core processors, but that pales to what researchers at Stanford's Engineering Center for Turbulence Research (CTR) have created with a new record in computational science. The Stanford researchers successfully used a supercomputer with more than one million computing cores to solve a complex fluid dynamics problem; that being the prediction of noise generated by a supersonic jet engine....

Far-reaching Problem In Computer Simulations Deciphered By Scientists
2013-01-03 12:19:27

DOE/Lawrence Berkeley National Laboratory Because modern computers have to depict the real world with digital representations of numbers instead of physical analogues, to simulate the continuous passage of time they have to digitize time into small slices. This kind of simulation is essential in disciplines from medical and biological research, to new materials, to fundamental considerations of quantum mechanics, and the fact that it inevitably introduces errors is an ongoing problem for...

Are We Living In The Matrix?

April Flowers for redOrbit.com - Your Universe Online In 1999, the first in a series of movies came out suggesting that we are all parts of a computer simulation. The Matrix was the ultimate horror story of artificial intelligence gone wrong. But could it be true? Could we be living in a computer simulation? And how would we ever know? A British philosopher, Nick Bostrom, hypothesized that we might in fact be living in a computer simulation being run by our descendants in the future....

Study Properties Of Smallest Water Droplets Known
2012-08-16 10:48:49

Brett Smith for redOrbit.com - Your Universe Online Using computer modeling, researchers at the University of California, San Diego and Emory University have revealed new details surrounding hexamer structures that are considered to be the smallest droplets of water. "Ours are the first simulations that use an accurate, full-dimensional representation of the molecular interactions and exact inclusion of nuclear quantum effects through state-of-the-art computational approaches,”...

Get a behind-the-scenes look at the mathematics underlying movie special effects at this free public event, July 11 at 6:15 PM at the Hyatt Regency Minneapolis. What do Avatar, The Chronicles of Narnia, X-Men, Harry Potter, and Pirates of the Caribbean have in common? Simulated physics. That´s right. Making visual effects real for movie audiences–be it Avatar´s vast ocean surface or rising water levels in The Deathly Hallows–requires quite a bit of physics and...

Simulator computes evacuation scenarios for major events Predicting how large numbers of visitors to major events will behave is difficult, even using evidence based on past experience. To prevent disasters, however, the police, rescue services and event organizers have to be able to identify dangerous bottlenecks, hidden obstacles and unexpected escape routes in advance. A research group with engineers and computer scientists at Technische Universität München...
