Regarding the IBM Super-Computer that can simulate Nuclear tests. simulation is accomplished by solving in real time the simularneous equations that describe the Physical process. As a past lecturer on Nuclear Reactor SImulation at the Harwell Reactor Schoo, and later an IBM instructor in Scientific Computing,l I have an interest in the subject. A simulator is as good as the equations that it solves. You can find solutions that are previously unknown, but not corrections to the equations, other than by comparing the simulation results with the experimential results under similar conditions. Also the speed of a computer can be slow if the simulation is scaled down in time. Speed is critical only for recording physical experimental data or for control purposes.
