This paper aims to provide a contribution to the research in physics education regarding the interplay between mathematics and physics in teaching and learning physics at the university level. The argument is developed through a study focused on the historical case study of the blackbody that led Planck to make one of the most significant…

Reviews the developments in S-matrix theory over the past five years which have made it possible to derive results characteristic of quark models without any need to postulate the existence of physical quarks. In the new approach, the quark patterns emerge as a consequence of combining the general S-matrix principles with the concept of order.…

The extended Galilean transformation carries an inertial frame into a rigid frame with uniform spatial, but arbitrary translational acceleration. Besides being useful in discussing the equivalence principle, this transformation provides a physical interpretation for the theorem in nonrelativistic quantum mechanics, that we cannot coherently…

Shows how to extend Wigner distribution functions, and Weyl correspondence between quantum and classical variables, from the usual kind of canonically conjugate position and momentum operators to the case of an angle and angular momentum operator pair. (Author/GA)

This paper presents a derivation of the number given by Fermi in 1925, in his semiclassical treatment of the motion of an electron in the field of two stationary positive charges, for Bohr quantization of the electron orbits when the stationary charges are positive, and applies it to an electron moving in the field of a stationary dipole.…

Conflicting views have been put forward on the derivation of the distribution of solubilized molecules among micelles. This stems from failure to consider the arrangement of the solubilized molecules in the micelles. In the treatment presented enthalpy effects are ignored as they are not amenable to a simple general theory. (Author/BB)

Shows that von Neumann's mathematical theorem on composite systems acquires a transparent physical meaning with reference to a suitable physical example; a composite system in a state of definite angular momentum. Gives an outline of the theorem, and the results are restated in Dirac's notation, thus generalizing von Neumann's results which were…

This report contains abstracts of new technical reports and other documents resulting from research supported by the directorate for Applied Science and Research Applications of the National Science Foundation. Research reports from current programs include work in the areas of public policy and regulation; public service delivery and urban…

Provides abstracts of papers dealing with various aspects of science, engineering, mathematics, computer science, science education, and other academic fields. Science education abstracts focus on such topics as microcomputers, industry relationships, curriculum and instructional strategies. Program descriptions are also included. (JN)

Discussions of research efforts in areas supported by the National Science Foundation (NSF) are presented. These areas include: (1) mathematical and physical sciences (mathematical sciences, computer science, physics, chemistry, and materials research); (2) engineering (electrical, computer, and systems engineering, chemical and process…

This report provides data on Federal funds for research and development for the period from 1977-1979. The data show Federal R&D funding levels as reported by 94 agencies in March through May of 1978, and are based on agency budgets as incorporated in the President's 1979 budget message to Congress. This report is based on three years of the 1979…

This document provides highlights of research efforts supported by the National Science Foundation (NSF) in the areas of mathematics, physical sciences, and engineering; astronomical, atmospheric, earth, and ocean sciences; science education; research applied to national needs; and scientific, technological, and international affairs for fiscal…

This publication was prepared to help research scientists keep abreast of literature in their field. Twenty-two fields of science and technology are included in the translations. A list of the subject fields and the included group structure is presented. Reports and translations for each field include bibliographical data as well as descriptors…

THIS IS A REPORT OF A DAY'S WORKSHOP ON THE COLLEGE SCIENCE CENTER, WITH A GROUP OF ARCHITECTS, COLLEGE ADMINISTRATORS, AND FACULTY. THE EMPHASIS WAS ON A DISCUSSION OF THE CONSOLIDATION OR CENTRALIZATION OF SCIENCE FACILITIES ON THE LIBERAL ARTS CAMPUS. SPECIFIC TOPICS INCLUDED--(1) WHY BUILD A SCIENCE CENTER, (2) BRIDGING OVER SUBJECT…

In 1965, the National Science Foundation began an experiment in institutional funding, the Science Development (SD) program. Setting as dual goals an upgrading of the science capabilities of second-tier universities and a broader geographical distribution of scientific resources throughout the nation, this program awarded over $130 million to…
