A known but often overlooked property of optical monochromators is discussed in view of its current applications. It is shown that grating and prism monochromators hold on to light for time durations proportional to resolving power and that the dispersing ability of monochromators extends to pulses of arbitrarily short duration. (SK)

Presents background information concerning microwave properties useful to persons considering the suitability of various materials to microwave processing. (CS)

Considers the electrostatic problem of a point charge in a domain bounded by conducting planes. Lists all such domains for which a solution by images exists, describes the image charge arrays in familiar crystallographic terms, and gives an illustrative example. (Author/GS)

Reviews calculations that derive an order of magnitude expression for the size of man in terms of fundamental constants, assuming that man satifies these three properties: he is made of complicated molecules; he requires an atmosphere which is not hydrogen and helium; he is as large as possible. (CS)

Two equipment systems are described: mechanical start-stop gates for air tracks, and a large-scale magnetic induction demonstration. (CS)

Using the example of Hans Christian Oersted's (1777-1851) discovery that magnetic fields surround currents as a focal point, it suggests, by using different historical examples, that science and history be brought together in a kind of conjunction for scholarly research and classroom purposes, for both scientists and nonscientists. (SK)

Discussed is the utilization of surface ocean waves as a potential source of power. Simple and large-scale wave power devices and conversion systems are described. Alternative utilizations, environmental impacts, and future prospects of this alternative energy source are detailed. (BT)

Examines Drude's classical (1900) theory of electrical conduction, details the objections to and successes of the 1900 theory, and investigates the Quantum (1928) theory of conduction, reviewing its successes and limitations. (BT)

Using practical applications of the principles of elementary physics, the author details how beekeepers can monitor the weight of their colonies. The weighing technique described involves no costly equipment, is not limited to a single colony, and is developed from the principles of physics for rigid body equilibrium. (BT)

Details the procedures used in utilizing the hydrogen bubble incident at Three Mile Island to relate these basic chemical principles to nuclear chemistry: gas laws, Le Chatelier's principle and equilibrium, and stoichiometry. (CS)

This is a part of a presentation made in 1978 at the symposium on the Influence of Modern Scientific Ideas on Society organized by UNESCO in West Germany. An analysis of Einstein's intellectual courage and behavior is discussed. (HM)

Analyzes the concepts of physical time and of the measurement of the magnitude of time, and examines the International System of Units (SI). A proposal for the use of the Einstein system (ES) is also included. (HM)

Describes the production of computer-generated author and key-word-from-title indexes to book reviews in physics: the sources, the processing, and the storage and retrieval system. Data elements available from the indexes include author, title, local call number, publisher, year of imprint, month and year of publication, series, cost, and…

A discussion of the aerodynamics of a boomerang as it relates to that of a golf ball. (BB)

Celebrates the centennial of Einstein's birth with an eight-page pictorial biography and two special articles: (1) Einstein the catalyst; and (2) Unitary field theories. His special and general theories of relativity and his contributions to quantum physics and other topics are also presented. (HM)
