Simulating physics with computers
International Journal of Theoretical Physics, 1982This chapter describes the possibility of simulating physics in the classical approximation, a thing which is usually described by local differential equations. But the physical world is quantum mechanical, and therefore the proper problem is the simulation of quantum physics. A computer which will give the same probabilities as the quantum system does.

Abstract This chapter is a primer on physical computation. It distinguishes between abstract and concrete computation. It introduces the notion of simulation of one physical system by another and the more specific notion of computational simulation of a physical system by a computing system.

Computations in fusion Physics
Applied Mathematics and Computation, 1986The modern approach to nuclear fusion uses inertial confinement by a high-power laser beam, and the computer codes used to simulate the plasma behaviour now contain a lot of physics. Nonlinear interaction of a laser with a turbulent plasma is a major topic of experimental and numerical study. Simulation can be on either the particle or the hydrodynamic
