This 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 …

Computational physics is physics done by. means of computational methods. Computers do
not enter into this tentative definition. A number of fundamental techniques of our craft were …

In this chapter, the authors discuss a part in an effort to analyze the physical limitations of
computers due to the laws of physics. It is a result of computer science that a universal …

T hpheoretical computer scientists, like their counterparts in physics, suffer and benefit from
a high level of intellectual machismo. They believe they have some of the biggest brains …

The middle essay of the seven here reprinted is Professor Bohr's account of his discussions
over the years with Einstein. A charming feature is the illustration of" apparatus" proposed by …

This work is a part of an effort to analyze the physical limitations of computers due to the
laws of physics. For example, Bennett'" has made a careful study of the free energy …

Computing processes are ultimately abstractions of physical processes; thus, a
comprehensive theory of computation must reflect in a stylized way aspects of the underlying …

An intelligent being who, at a given moment, knows all the forces that cause nature to move
and the positions of the objects that it is made from, if also it is powerful enough to analyze …

Our topic can be approached from a variety of points of view, but these lectures will adopt
the perspective of a theoretical physicist (that is, it's my perspective and I'm a theoretical …
