Describes controversial examples attributed to the pursuit of science and research activities conducted by the Los Alamos Scientific Laboratory to solve present major physical problems. Indicates the necessity of convincing society that untrammeled investigation in science is the only path to derivation of practical public benefits. (CC)

Experiments performed at Brookhaven National Laboratories on the energy states of free atoms are described. Included are the techniques and the significance of the measurements. (Author/TS)

Discusses the contributions made by the field of quantum electrodynamics to the understanding of positroniums. (MLH)

The difference in time between the emission and reception of light is called the "lookback" time. This article explores implications of lookback time and explains some of the puzzling questions posed by the scientific observation of cosmic history. Provides several pictures and diagrams. (YP)

New research topics have been brought about by the acceleration of nitrogen nuclei to the energy of 36 billion electron volts. Describes experiments on tumor cells, cosmic rays, and nuclear fission performed with the Bevatron at the Lawrence Berkeley Laboratory. (TS)

Detection of neutrino decay may have profound consequences for both particle physics and cosmology, providing a deep connection between physics of the very large and physics of the very small. Describes this link and discusses the nature and status of the search for decaying neutrinos. (Author/JN)

Describes the discovery and characteristics of superconductors. Discusses some experiments on the levitation of a magnet over a superconductor. (YP)

Describes a research program in which high school students act as individual investigators on scientific projects. Probes how to better introduce current scientific research topics and methodologies into the classroom. Provides an example using fractals. (MVL)

Describes the use of two tiny light bulbs and a cloth grating to construct a semiquantitative experiment for determining the wavelength of light from an interference pattern. (WRM)

Current and post World War II scientific research at the Los Alamos National Laboratory (New Mexico) is discussed. The operation of the laboratory, the Los Alamos consultant program, and continuation education, and continuing education activities at the laboratory are also discussed. (JN)

Describes the organization and completion of a scientific field trip for a group of high school physics students that was organized primarily around a study of the Manhattan Project. The group visited the Trinity site, Los Alamos, several museums, and the National Radio Astronomy Observatory Very Large Array. Contact information for the various…

The development, role, and current research in particle physics at the Fermi National Accelerator Laboratory are reviewed, including discussions of its mission to understand the structure of matter, a brief history of particle physics, and the nature and applications of superconductivity, among other topics. (JN)

Describes a short undergraduate course built entirely around a research trip to an astronomical observatory. (WRM)

Discusses possibilities for the application of telepresence to physics and teaching. Telepresence allows a computer user to effectively be present at some other location through the use of remote cameras, sensors, and controls. (WRM)
