Discusses new problems arising from the growing observational data through radio telescope arrays, involving the origin of radio sources, apparent superluminal velocities, conversion of radio sources to relativistic particles, and the nature of compact opaque and extended transparent sources. New physics may be needed to answer these cosmological…

Presents two arguments concerning the role of the photon. One states that the photon is just another particle distinguished by a particular value of charge, spin, mass, lifetime, and interaction properties. The second states that the photon plays a fundamental role with a deep relation to ultimate formulas of physics. (GS)

Reviews the debate between physicists Compton and Millikan over cosmic radiation in the 1930's and the resultant social repercussions against science. (SL)

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)

Discusses reasons why physics is considered contrived and abstract, and suggests ways to teach aspects of physics that show relations between human beings and between man and nature. (MLH)

Discusses the development of recent analytical techniques that can give detailed information on thin-film structures. (HM)

Traces the history of the discovery of spin and its place in quantum mechanics. (MLH)

Traces the history of the development of spin and wave mechanics. (MLH)

Reviews the subject of the electronic structures of metals which produce magnetism. (SL)

Presents a brief overview of the important processes and techniques used industrially for forming thin films. (HM)
