Presents aspects of multipole radiation theory suitable for a senior level course in nuclear physics. (SL)

Discusses the development of the Rutherford-Bohr atom. Indicates how the objectives of the historian may differ from those of the retrospecting or historicizing physicist. (Author/SK)

Shows how the good-as-new postulate leads to the exponential function, which in turn leads to a complete probabilistic description of the decay of an aggregate of identical excited atoms. (Author/GA)

Calculates the energy-band structure of noninteracting electrons in a one-dimensional crystal using exact and approximate methods for a rectangular-well atomic potential. A comparison of the two solutions as a function of potential-well depth and ratio of lattice spacing to well width is presented. (Author/GA)

Discusses an experiment involving a linear chain of falling dominoes. The time for a chain of N equally spaced dominoes to fall is measured and a plot is made between the time and N. The experimental data are compared with the predictions of theory. (Author/GA)

Points out that quantum mechanics interpretations, using Heisenberg's Uncertainty Relations for the position and momentum of an electron, have their drawbacks. The interpretations are limited to the Schrodinger theory and fail to take into account either spin or relativity. Shows why spin cannot be ignored. (Author/GA)

Surveys the research of scientists like Joule, Kelvin, Maxwell, Clausius, and Boltzmann as it comments on the basic conceptual issues involved in the development of a more precise kinetic theory and the idea of a kinetic atom. (Author/SK)

Schrodinger-Einstein correspondence reveals the fact that deBroglie's doctoral thesis provided Schrodinger with much of the background and inspiration that enabled him to invent wave mechanics. (GA)

Indicates that although Newton's achievements were rooted in an atomistic theory of matter resembling aspects of modern nuclear physics, Dalton developed his chemical atomism on the basis of the character of the gross behavior of substances rather than their particulate nature. (Author/SK)

Focusing on history of physics, which began about 600 B.C. with the Ionian Greeks and reaching full development within three centuries, suggests that the creation of the concept of the atom is understandable within the context of Greek physical theory; so is the rejection of the atomic theory by the Greek physicists. (Author/SK)

Presents history, nature of evidence evaluated, and philosophical questions to justify the view that experiments on parity nonconservation were "crucial" experiments in the sense that they decided unambiguously and within a short period of time for the appropriate scientific community, between two or more competing theories or classes of theories.…

The theory of canonical transformations and its development are discussed with regard to its application to Hutton's principle. Included are the derivation of the equations of motion and a lack of symmetry in the formulaion with respect to Lagrangian and the fundamental commutator relations of quantum mechanics. (Author/SA)

College physics textbooks emphasize the conclusions of research at the expense of the context of inquiry in physics. The latter should be given specific consideration in at least one of the student's physics courses. An excellent focus for this consideration would be the process of theory evaluation as indicated in this paper. (Author/TS)

Presents a new derivation based on simple theorems of probability theory for the established system of equations describing successive decay transitions of quantum systems. It is indicated that this derivation that has a quantum-mechanical foundation might be more appealing to applied physicists than other derivations. (HM)

Explains the discrepancy between the principle-of-equivalence and the general theory of relativity in calculating the deflection of light by the sun. Shows that the total deflection is the sum of the deflection given by the principle-of-equivalence, and the deflection of infinitely fast particles. ( GA)
