Dirac's classical conclusions, that the values of e2, M and m are constants and the quantity of G decreases with time. Evoked considerable interest among researchers and traces historical development by which further experimental evidence points out that both e and G are constant values. (PS)

Prepared by the National Academy of Sciences, the report suggests implications of the 25 percent cut in support of physics programs as possible loss of scientific supremacy, employment problems, and the abandonment of whole subfields of research. (CP)

A Discussion of attempts to understand the great inter-relationships among all areas of knowledge" by Neils Bohr, a physicist, and others. (SE)

discusses the cosmology theory of a black hole, a region where an object loses its identity, but mass, charge, and momentum are conserved. Include are three possible formation processes, theorized properties, and three way they might eventually be detected. (DS)

Astronomers are using aspects of the fundamentals gleaned by the study of the dynamics of superfluids to help understand what happens inside the intensely hot, collapsed, neutron stars that spin and radiate as pulsars. Current research, focusing on the puzzling behavior of helium in its superfluid state, is discussed. (JN)

Following a short review of the history of cosmic-ray astrophysics and a discussion of the accumulated data, pointing to the need for isotope measurement, the theory of heavy-element nucleosynthesis is reviewed to provide a basis for the interpretation of the cosmic-ray data. (Author/JN)

Asks questions relating electrical resistivity and observed size effects. Electron mean free path and thermodynamic fluctuations are discussed. Experiments with granular aluminum are outlined and described which allow the study of size effects, as well as the coupling and the transport processes between them. (CS)

This article is a preview of the book, "Physics News in 1980." Five research areas are reviewed: high energy particle accelerators, fusion reactors, solar cells, astrophysics, and gauge theories. (Author/DS)

The goals of solar photovoltaic technology in contributing to America's future energy needs are presented in this study conducted by the American Physical Society. Although the time needed for photovoltaics to become popular is several decades away, according to the author, short-range applications are given. (Author/SA)

Discusses new studies in neutron physics within the last decade, such as ultracold neutrons, neutron bottles, resonance behavior, subthreshold fission, doubly radiative capture, and neutron stars. (MLH)

Describes an experiment in which Fresnel diffraction patterns were observed with a beam of slow neutrons of wavelength 4.33 Angstroms. (MLH)
