摘要:

That Rudolf Clausius invented the entropy concept is well known, but less familiar is the argument that served as his inspiration. This paper traces the development of Clausius’ ‘‘transformation theory’’ of heat, which finally persuaded him to define the measure of transformation equivalence he called entropy.

摘要:

In the summer of 1985 we ran a workshop for high school physics teachers, sponsored by the National Science Foundation under its program of Honors Workshops for Pre‐College Teachers of Science and Mathematics. The summer experience consisted of a five‐week workshop and a four‐week industrial experience. The teachers had a wide variety of backgrounds and needs, which were accommodated in the workshop. This paper describes how the workshop was run, what activities were successful, and where we encountered problems.

摘要:

This article describes a seminar on the elements of probability and random processes that is computer centered and focuses on Monte Carlo simulations of processes such as coin flips, random walks on a lattice, and the behavior of photons and atoms in a gas. Representative computer programs are also described.

摘要:

A simulated heat engine is described which can raise weights to a higher level. The engine’s pressure and volume data, when plotted on apVdiagram, give a closed cycle whose area is in good agreement withmgh, the work accomplished during the cycle.

摘要:

The use of the Schrödinger equation in classical physics was begun in 1950; in the classical context it is known as the parabolic wave equation. The derivation of the parabolic wave equation from the full classical wave equation is analogous to deriving the Schrödinger equation from the Klein–Gordon equation. An introduction to the Schrödinger equation by this route could be of help in introductory quantum‐mechanics classes.

摘要:

According to the big bang theory, the universe began about 15 billion years ago and has been continually expanding ever since. If certain elementary physical concepts arenaivelyapplied to this cosmological theory, it can lead to a paradox in which distant astronomical objects seem to have lain at distances from the Earth larger than the possible size of the universe. The paradox is resolved by using concepts from general relativity theory. These concepts may appear startling to some readers.
