Describes a four page paper written by S. Bose who helped found quantum statistics. The consequences of the paper to modern physics are presented. Contrasted are the scientific relationships of Einstein, Dirac, and Bose. (GH)

Describes how to produce a rainbow in the classroom using a laser and a large sphere, or a partial rainbow using a cylinder of water and a light source. (BR)

Examines the observations and experiments conducted in the 18th century to detect and measure light pressure. The reception of these results reveals another scientific strategy besides confirmation and refutation, namely, estimation of parameters. (Author/GS)

Briefly describes a physics course for nonmajors which focuses on light and color. (PEB)

Discusses records made of the London Weather Centre indicative of concentrated sunshine symmetrically about noon, which provides a probability of sunshine occurring on vertical surfaces to be greatest for south facing walls. Concludes that design recommendations should be based on available, rather than on theoretically possible, sunshine duration…

Explores the wave-particle nature of light by raising and answering the following question: "Can particle theory satisfactorily explain the experimental facts for light refraction?" (GS)

The effects of varied lighting and coloring in the classroom environment were examined on the behavior of seven severely handicapped 8 to 11 year olds with behavior problems. Analysis of changes in systolic blood pressure indicated that Ss were more comfortable and relaxed in the experimental room (in which the fluorescent lights were replaced by…

The purpose of this report is to acquaint all personnel with some technical aspects of micrographics. The various film types used in the production of microfiche are discussed, including silver halide, diazo, and vesicular films. Other imaging systems used in micrographics are reviewed, and a basic introduction to sensitometry is given. The…

This document contains a U.S. Navy Rate Training Manual and Nonresident Career Course which form a self-study package to teach the theoretical knowledge and mental skills needed by the Opticalman Third Class and Opticalman Second Class. (Opticalmen maintain, repair, and overhaul telescopic alidades, azimuth and bearing circles, binoculars,…

This module is designed to give the learner an understanding of the nature of light and how its properties are used in the design of spectrophotometers. Problems promote the use of spectrophotometers in qualitative analysis, the optical elements used in a monochromator, and the physical properties of the prism and the diffraction grating. Other…
