PhysicsGlobal Number Cruncher
With a colorful, animated slide show, this Web site introduces visitors to the way vast streams of physics data will flow, starting later this year, from the world’s most powerful particle accelerator to 7,000 physicists around the world. Potentially packed with revelations about matter, energy, and the universe, some 15 million-billion bytes of information per […]
