How computers push on the molecules they simulate |
January 04, 2013
Simulations are essential to test theories and explore what's inaccessible to direct experiment. Digital computers can't use exact, continuous equations of motion and have to slice time into chunks, so persistent errors are introduced in the form of "shadow work" that distorts the result. Scientists have learned to separate the physically realistic aspects of the simulation from the artifacts of the computer method.
