Constantinos Daskalakis, an assistant professor in MIT’s Computer Science and Artificial Intelligence Laboratory, has exported those techniques to game theory, a branch of mathematics with applications in economics, traffic management -- on both the Internet and the interstate -- and biology, among other things. By showing that some common game-theoretical problems are so hard that they’d take the lifetime of the universe to solve, Daskalakis is suggesting that they can’t accurately represent what happens in the real world. http://phys.org/news176978473.html Technology Mon, 09 Nov 2009 09:20:01 EST news176978473 Nobel Physics prize winner Vitaly Ginzburg, who helped develop the Soviet hydrogen bomb, has died at age 93, the Russian Academy of Sciences said Monday. http://phys.org/news176963593.html Physics Mon, 09 Nov 2009 05:00:02 EST news176963593 (PhysOrg.com) -- NASA will award $1.65 million in prize money Thursday to a pair of innovative aerospace companies that successfully simulated landing a spacecraft on the moon and lifting off again. http://phys.org/news176456283.html Space & Earth Tue, 03 Nov 2009 07:50:01 EST news176456283 (PhysOrg.com) -- Finally, an optical frequency comb that visibly lives up to its name.
