Presents a picture of the conditions in which discoveries are made and the effort required to reconstruct the conditions in which past discoveries were made. (SL)

Discusses establishment, functions, program development, policy considerations, and future prospects of the Latin American Centre for Physics (CLAF) in Rio de Janeiro, Brazil. (SL)

Describes an experiment that used a four-element radio interferometer to illustrate gravitational deflection as predicted by the theory of general relativity. (MLH)

Inquires into the individual names and dates which are associated with the various perfect gas laws on the basis of published and historically researched works. Indicates the presence of eight features in giving a scientist credit for a scientific discovery. (CC)

Discusses the technology used for transduction between electrical and acoustical signals. In particular, the recent developments in microwave ultrasonics research are presented. (JP)

Reviews the Hafele-Keating experiment on relativistic changes in eastward and westward moving cesium atomic clocks. Recommends the use of the Sagnac effect to remove the east-west time asymmetry and of the general-relativistic effect to elucidate the clock-rate changes. (CC)

Details of the generator used in a proton-synchrotron particle accelerator are described. (PS)

Describes the discoveries and achievements in the field of nuclear physics before 1932. Particular emphasis is given to Ernest Rutherford, Francis Aston, and the Cavendish Laboratory. (TS)

Satyendranath Bose was first to prove Planck's Law by using ideal quantum gas. Einstein credited Bose for this first step in the development of quantum statistical mechanics. Bose did not realize the importance of his work, perhaps because of peculiar academic settings in India under British rule. (PS)

Physicists and engineers advance the state of several arts in the design of gravitational-wave detection equipment. Provides background information and discusses the equipment (including laser interferometer), its use, and results of several experimental studies. (JN)

The second of two parts (part 1 in v20 n4, p222, Apr 1982) focuses on experimental techniques used to study cosmic-ray isotopic composition, experimental results, and comparison between cosmic-ray source matter and solar-system material. Several models for nucleosynthesis and evolution of cosmic-source matter are also discussed. (Author/JN)

The acoustics of speech production allows the prediction of resonances for a given vocal tract configuration. Combining these predictions with aerodynamic theory developed for mechanical whistles makes theories about human whistling more complete. Several experiments involving human whistling are reported which support the theory and indicate new…

Summarizes information on the properties of synchrotron radiation and describes laboratories in the United States specializing in this science, including facilities at the National Bureau of Standards, University of Wisconsin, Stanford, and Brookhaven. (CS)

The discovery of a superconducting organic compound is reported. The compound, (TMTSF)-2, has no metal in its composition, and the author believes that it is the precursor of a family of superconducting organics. (Author/SA)

Discusses the role of the Francis Bitter National Magnet Laboratory of the Massachusetts of Technology, and its significance in the world of research. Applications of research on magnetism to medicine are emphasized. (SA)
