The "Hands on CERN" education project makes it possible for students and teachers to get close to the forefront of scientific research. The project confronts the students with contemporary physics at its most fundamental level with the help of particle collisions from the DELPHI particle physics experiment at CERN. It now exists in 14 languages…

Describes the procedure, equipment, results, and weaknesses of an experiment conducted by Nevil Maskelyne at Schehallien peak in Scotland; the purpose of the experiment was to collect data for the calculation of the mean density of the earth and to measure the universal gravitational constant. (MLH)

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)

Physics teachers in secondary schools usually mention the world's largest particle physics laboratory--CERN (European Organization for Nuclear Research)--only because of the enormous size of the accelerators and detectors used there, the number of scientists involved in their activities and also the necessary international scientific…

Addresses the question of the social responsibility of physicists, particularly with regard to their quest for knowledge which may endanger other people. (SL)

Discusses the importance of climatology and world centers where climatologic research is conducted. (MLH)

Describes a course based on the scientific approach to the search for extraterrestrial intelligence. Explores the biological and technological aspects of the search and the social implications of possible contact. (Author/CCM)

Discusses the atmospheric characteristics of the earth and their implications for the development of life on earth-like planets. Indicates that the chance of life developing on other planets is not as great as men might have thought. (CC)

Discusses the history of electron theory from 1897 to 1987. Includes the works of some physicists, such as Thomson, Lorentz, De Broglie, Bohr, Pauli, Dirac, Feynman, Wheeler, Weinberg, and Salam. (YP)

Discusses theories underlying Newtonian and non-Newtonian fluids by explaining flow curves exhibited by plastic, shear-thining, and shear-thickening fluids and Bingham plastic materials. Indicates that the exact mechanism governing shear-thickening behaviors is a problem of further study. (CC)

Discusses the scientific objectives of the space missions to illustrate the role of scientists in space-borne research studies. Included is a tentative list of demonstration experiments worth conducting in order to attain pedagogical goals. (CC)

Discusses the nature of physics by examining what physicists do in relation to what mathematicians, chemists, and biologists do. Also discusses the future of physics and physics education, focusing on four frontiers waiting for a breakthrough. These include high energy, many degrees of freedom, life, and zero-time frontiers. (JN)

Discussed is the physicists' impact on the revolution in the earth sciences particularly involving the overthrow of the fixist notions in geology. Topics discussed include the mobile earth, the route to plate tectonics, radiometric dating, the earth's magnetic field, ocean floor spreading plate boundaries, infiltration of physics into geology and…

Summarizes the scientific activities of the Apollo program, including findings from analyses of the returned lunar sample. Descriptions are made concerning the possible origin of the moon and the formation of the lunar surface. (CC)
