Phun, the interactive physics simulator, is now available for Mac OS X.
Be warned. If you like physics or tinkering around with things, this program could be a huge time sync sink. (I’ve been futzing with SyncML too much lately.) I was playing with it in (ugh) Windows XP last time I was in New Orleans, [...]

Simulations of real systems make it possible to test “what if” questions, and compare the results with what did happen. For example, I am working on a study in which a stimulus pulse turns on and off while a spiral wave rotates about an obstacle. We can ask, “What happened to the spiral wave following [...]
