A simplified relativistic force transformation equation is derived and then used to obtain the equation for the electromagnetic forces on a charged particle, calculate the electromagnetic fields due to a point charge with constant velocity, transform electromagnetic fields in general, derive the Biot-Savart law, and relate it to Coulomb's law.…

This article discusses superheated liquids and attempts to link them to vapor explosions. (BB)

Deals with the wastes generated in nuclear power plants and the health risks involved as compared to those of wastes generated by coal-fired plants. Concludes that the risks of nuclear power plants are many times smaller than the risks from alternative energy resources. (GA)

Developments in the nuclear industry and nuclear research for 1978 are summarized. Included are developments in uranium production, prices, and national and international legislation. (BB)

Summarizes Charles Wheatstone's 1843 paper introducing the Wheatstone bridge and the rheostat. (SL)

A short history of Newton's work in optics, mathematics, and astronomy. (BB)

Describes the life and work of physicist Robert A. Millikan. (SL)

Reviews research and apparatus utilized in the study of the states and characteristics of materials at very high temperatures and pressures. Includes three examples of the research being conducted. (SL)

Describes a method of acquainting physics and astronomy students with the general theory of relativity. (SL)

Discusses a problem (on page 523 of "College Physics," by Sears, Zemansky, and Young, published by Addison-Wesley, 1980) concerning light bulbs and resistance. Shows why the assumption of constant resistance is unrealistic and provides guidelines for revision. (DH)

Discusses some of the physical processes involved in the freezing of water. Traces the work of a variety of researchers who have discovered numerous variables involved in the complexities of ice. (TW)

The ontological problem is "what exists?" The answer regarding the part of consciousness which is related to left hemisphere is that only individual discrete objects exist; objects are regarded one at a time. The answer regarding the part of consciousness which is related to right hemisphere is only comprehensive entities exist; each…

Outlined is the history of superconductivity and described are the physical and chemical principles upon which it rests. Some possible applications of superconductors are considered. (RH)

Addresses the question of why a dog's eyes appear red and glow when a flash photograph is taken. Conditions for the red-eye effect, light paths involved, structure of the eye, and typical cameras and lenses are discussed. Also notes differences between the eyes of nocturnal animals and humans. (JN)

Outlines how the radiative properties of a surface can be tailored so as to be favorable for efficient utilization of energy. The radiative properties of concern are transmittance, reflectance, absorptance, and emittance. (JN)
