摘要:

Apparatus for demonstrating some optical properties of thin films to large audiences is described. In addition to all the thin film interference effects, one can demonstrate (a) the phase shift experienced by the electric vector parallel to the plane of incidence when passing through the Brewsterian angle and (b) the phase shift at a metal-dielectric reflection. The apparatus depends for its success upon the high brilliance and saturation of the reflected interference colors from a composite metal-dielectric film. Its construction and properties are described.

摘要:

This paper gives a discussion of massless particles, especially the two-component neutrino and the photon, in the light of modern ideas about space reflection. The emphasis is on the physical arguments and mathematical details are omitted.

摘要:

The apparatus described in this article is a model for the simple kinetic theory of an ideal gas. It dramatically demonstrates the concept that the pressure a gas exerts on the walls of its container is due to the combined effect of the many individual impacts of the gas molecules on those walls. A massive moving system integrates the effect of many small equal impulses to produce a steady deflection whose magnitude is accurately predicated by simple theory.

摘要:

This article is a description of air-suspended “pucks” for investigating the conservation of momentum between two colliding bodies. The film of air separating the pucks from their supporting surface provides an extremely small coefficient of friction. The experiment confirms that momentum is conserved with errors of less than 5%. The operating principles of these devices are easily applicable to other experiments requiring motion with negligible friction.
