Try dragging your mouse diagonally on the applet above!

PLEASE NOTE: I've just moved this web site here, to its new home. Some parts work, but it is not completely functional yet. Check back soon!

Keywords: space plasma physics, Aurora Borealis, Northern Lights, magnetic fields, Alfven waves, magnetosphere, ionosphere, electrojet, Farley-Buneman instability, solar dynamo, particle simulation, implicit methods, dusty plasma, double layers, sudden cardiac death, computational biology, thermal regulation, spiral waves, scroll waves, excitable media, dynamical systems

Play CyberCardiologist! Save your patient from cardiac spiral waves. Then kill him again! Learn about the basic properties of action potentials in the heart at the same time. Did you know? That the wiggling of the Earth's magnetic field lines by the solar wind can accelerate electrons to high enough velocities to produce the Northern Lights? That a tremendous electrical current flows 60 miles above the Earth's surface? That the Sun shouldn't have a magnetic field anymore, but somehow still manages to have one? That if you drop dust particles into an ionized gas, they sometimes arrange themselves into a crystalline structure? That you and your heart may only be a software error away from death? That computer simulation techniques may be used to investigate all of the above? If not, read on...
