This paper describes the events following the news of Oersted's discovery of the effects of a current of electricity on a magnetic needle. It focuses on Biot and Savart's law which expresses the force between a current element and a "molecule of magnetism" that can be deduced from Ampere's law of interaction between two current elements.…

The 1977-78 annual Graduate Student Survey analyzes information supplied by graduate physics students and also includes graduate astronomy students. Highlights of the findings are: a continuing decline in the number of graduate physics degree recipients; the reassurance of a steadily improving job market for new physicists with graduate degrees; a…

The author initially describes the basic physical principles associated with energy and the rise of energy usage in the United States. Also discussed are the ways energy limits growth and its use in various sectors of society. It is suggested that the decentralization of America's electrical system will save a great deal of energy. A variety of…
