Discusses the contributions of G. N. Lewis to chemistry, focusing on his formulation of the basic principle of the chemical bond--the idea that the chemical bond consists of a pair of electrons held jointly by two atoms. (JN)

Traces the development of basic radiation physics that underlies much of today's medical physics and looks separately at the historical development of two major subfields of medical physics: radiation therapy and nuclear medicine. Indicates that radiation physics has made important contributions to solving biomedical problems in medical…

Following an historical sketch of the development of relativistic quantum mechanics, a discussion of the still unresolved difficulties of the currently accepted theories is presented. This review is designed to complement and update the discussion of relativistic quantum mechanics presented in many texts used in college physics courses. (Author/SK)

Outlines the life of A. G. Vernon Harcourt, a founder of chemical kinetics, contributor to the purification of coal gas from sulfur compounds, inventor of the percentage chloroform inhaler, friend to Lewis Carroll, and instructor to the Prince of Wales. (CS)

This paper presents a summary of the history of the Department of Science Education at Teachers College, Columbia University along with a list of significant dates and occurrences within that department from 1892 to the present. It includes a list of doctorates and dissertation titles from 1921 to 1977. (CS)

Traces the history of the electron theory of the chemical bond. Nineteenth-century ideas on electrical combination, early twentieth-century theories of electrical attraction, and the contribution of G. N. Lewis's shared electron pair are among the topics considered. (JN)

Discusses the development of physical organic chemistry: (1) before 1920; (2) from 1920 to 1930; (3) from 1930 to 1940; and (4) after 1940. Major accomplishments in these periods are noted. (JN)

Traces the development of the study of geology and geological education in the United States during the 1700's. Addresses the influences of world travel, agriculture, and medicine on the inclusion of earth science into college curricula and self-instruction "civility books." (TW)

Until the eighteenth century, doctors were reluctant to use chemicals to alleviate pain because they accepted the religious/moral beliefs of their day, claiming that pain was beneficial for the body. Traces technical developments in the control of pain, discussing relationships of anesthesia to social, cultural, and scientific factors and…

Presents lecture outline comparing uniformitarianism with other philosophic approaches to earth study. Comparison is valuable since: (1) it provides insight into the character of geology and the meaning of the scientific method; and (2) it reveals the necessarily biased nature of all information. (Author/JN)

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 major events leading to the development of the octet rule. Three conclusions based on the work of Mendeleev, Abegg, Thompson, Kossel, Lewis, and Langmuir are considered as is the debate over the rule's validity. (JN)

Traces the origin and development of particle physics, concentrating on the roles of cosmic rays and theory. Includes charts highlighting significant events in the development of cosmic-ray physics and quantum field theory. (SK)

Describes the establishment of geology in the curricula of Tennessee colleges during the years from 1826 to 1850. The growth of a museum, the growth of learned societies, and the appearance of college courses in geology seem to be closely related. (Author/WB)

Presents evidence to support the author's viewpoint that Einstein's General Relativity Theory is related to concepts of chemo-electricity. (CS)
