Who needs supercomputers? - Just use your cell phone.



As a specialist editor of Computer Physics Communications I regularly get issues in the mail, and was amused to read in the latest edition an article entitled "Mobile Phone as a Platform for Numerical Simulation" by Filip Sala of Warsaw University. Today's cellphones have about the CPU power of PCs of the late 1990s, and there are 5 billion of the pesky little things. Sala managed to use one to simulate light propagation in linear and nonlinear media based on the one-dimensional Schrödinger equation and molecular reorientation in nematic liquid crystals. So who needs supercomputers? - just get your daughters off the phone. Well, maybe supercomputers are easier after all......
