NSF awards time on Blue Waters to seven new projects


Oct 1, 2014

The National Science Foundation (NSF) has awarded 14 new allocations on the Blue Waters petascale supercomputer at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign. Seven of the awards are for new projects.

Catching waves

Pretend you’re a contestant on Jeopardy! and the only category remaining is physics. You have no choice but to choose it, so you pick the lowest value choice and cross your fingers. Host Alex Trebek reads the answer: A branch of physics that is synonymous with televisions. The answer: What is plasma? Warren Mori, a professor of theoretical plasma at UCLA, says another term that can be used for plasma is hot or ionized gas. The best example of hot gas, or plasma, is one you see every day: the sun. Because plasma is synonymous with hot gas, plasma is often considered the fourth state of matter, explains Mori.
