Gives an analogy useful for explaining the experimental teleportation of a quantum-mechanical state to beginning physics students. (WRM)

Discusses the graphite to diamond transformation and a phase diagram for carbon. Describes high temperature-higher pressure experimental apparatus and growth of diamonds from seed crystals. Reviews properties of the diamond which suggest uses for the synthetic product. Illustrations with text. (GH)

Provides a chronicle of the work of Miss Leavitt in the field of variable stars during the early part of the 20th century. (CP)

Describes the various attempts, efforts and experiments that were carried out by the leading investigators in the field in their search for electromagnetic induction phenomena. (GA)

Provides the rationale for and examples of experiments designed to test the stability of protons and bound neutrons. Also considers the unification question, cosmological implications, current and future detectors, and current status of knowledge on proton decay. (JN)

Describes the reception accorded to John Tyndall in 1872-1873 in America. Tyndall, called the Apostle of Science, delivered a series of lectures on light with fascinating demonstrations in several cities during his visit. Press coverage and public reaction were overwhelming. Tyndall left the money earned from his lectures in a trust which is still…

Discusses the existence of matter in smaller groups known as clusters. Applications of the findings in scientific studies are presented as they relate to technology. (SA)

Discusses the existence of spirals in nature in general, supplying many examples, and explains how a particular organism, Phycomyces, accomplishes this feat. (GA)

Discusses a joint research program between several high school teachers and solar system astronomers in which data were collected on photoelectric observations of asteroids and minor planets via astronomical telescopes. (MLH)

Discusses the renewed interest in superconductivity research and describes the differences between the two basic types of superconductivity. (MLH)

Describes liquid surface holograms including their application to medicine. Discusses interference and diffraction phenomena using sound wave scanning techniques. Compares focussing by zone plate to holographic image development. (GH)

Reports on technological advancements in the fields of solar collectors, thermal storage systems, and solar heating and cooling systems. Diagrams aid in the understanding of the thermodynamics of the systems. (CP)

Describes the principle of the scanning optical microscope and explains its advantages over the conventional microscope in the improvement of resolution and contrast, as well as the possibility of producing a picture from optical harmonies generated within the specimen.

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