Photographs illustrate several principles of physics which can be observed in everyday situations. (CP)

Describes the difference between the approach of statistical probability and the deterministic approach to physical theories. Shows that it is near the truth to see physical theory as a hierarchical structure in which successively complex levels alternate between probabilistic and deterministic explanations. (Author/GA)

Distinguishes between the work done by the source and the work received by the system. Shows that a comparison of the magnitudes of quasistatic and nonstatic work can be carried out only through the use of the laws of thermodynamics. (GA)

Discusses a laboratory experiment in isotope production designed to help the students understand some of the concepts in elementary nuclear physics. (GA)

Derives an equation relating the internal pressure of a rubber balloon to its radius. Shows that the theoretical pressure curve is experimentally verifiable, and discusses the problem of equilibrium configuration of two interconnected ballons. (Author/GA)

The density matrix is used to obtain an expression for the mean value of any spin operator in the scattering of particles with arbitrary spin. The example of spin-1/2-spin-1 scattering is developed and physical information obtained by establishing connections with the polarization tensor and Wolfenstein observables. (Author/GA)

Among the light elements, nuclei with unequal numbers of protons and neutrons are highly unstable. Some survive just long enough to be detected and exhibit unusual regimes of radioactive decay. ( Autor/MA)

The electromagnetic field of a static charge in a moving medium is evaluated using elements of special relativity, residue calculus, and Fourier integration. Some of the concepts in electrodynamics that are of current research value are discussed. (BB)

Describes some of the discussion, correspondances and assumptions of Heisenberg. Includes clarifying and defending his explanation of the anomalous Zeeman Effect to the Quantum Physicists of his time. (GA)

Describes an approach for deriving expressions for thermal conductivity and dynamic viscosity which does not consider the net flow of energy or momentum across a plane. (SL)

In this new theory the gravitational force arises from a symmetry relating particles with vastly different properties. The ultimate result may be a unified theory of all the basic forces in nature. (Author/BB)

Considers the problem of determining the force on an element of a finite length line of charge moving horizontally with extreme relativistic speed through an evacuated space above an infinite plane ideal conducting surface. (SL)

Expressions to describe fringe contours in the region of interference of two coherent beams are derived for three combinations of plane and spherical wave geometrics. (Author/SL)

High-energy, relativistic nuclei were first observed in cosmic rays. Studing these nuclei has provided an opportunity for analyzing the composition of cosmic rays and for experimentally verifying principles governing the behavior of nuclear matter at high and super-high temperatures. Medical research using accelerated nuclei is suggested.…

Presents a simple means of visualizing and generating families of Rayleigh hysteresis loops. (SL)
