Comparisons are made for the particle-in-a-box, the harmonic oscillator, and the one-electron atom. A classical uncertainty principle is derived and compared with its quantum-mechanical counterpart. The results are discussed in terms of the statistical interpretation of the uncertainty principle. (Author/BB)

An approximate method is developed for elastic scattering at large angle in the framework of classical mechanics. A simple formula for differential cross-section is obtained. (Author/BB)

Describes the equilibrium states of a system composed of two interconnected, air-filled spherical membranes of different sizes. The equilibrium configurations are determined by the method of minimization of the availability of the system at constant temperature. (GA)

Explains the concept of jerk and resolves it, for planar motion, into two components: tangential-normal and radial-transverse. Expresses the normal component in terms of an affine differential invariant, the aberrancy. Uses aberrancy properties to establish geometrical properties of the jerk vector for plane motion. (GA)

Explains the properties and gives the derivations of Airy's functions for simple example problems on stress such as the cantilever beam and the tensional cross-bow. (GA)

Conventional expansions of solutions to Maxwell's equations in vector spherical harmonics apply only outside the sources. The complete solution, applying both inside and outside the sources, is given here. Harmonic time dependence is assumed. (Author/GA)

Shows using the special theory of relativity, how a body acted upon by a force with positive components could have one or two negative acceleration components. (GA)

Includes eleven short notes, comments and responses to comments on a variety of topics such as uncertainty in a least-squares fit, display of diffraction patterns, the dark night sky paradox, error in the dynamics of deformable bodies and relative velocities and the runner. (GA)

Two physics experiments are described, One, involving a laboratory cart accelerated along a level surface, examines the concept of inertial mass in translation and the other, using a solid cylinder, measures the moment of inertia of a wheel. Equations and illustrations are included. (MA)

Discusses problems relating to an international solution to the disposal of high-level radioactive waste problem. (SL)

Obtains the orbits with reference to the center of mass of two bodies under mutual universe square law interaction by use of the eccentricity vector which is equivalent to the Lenz vector within a numerical factor. (Author/SL)

Provides a detailed discussion of a Lagrange formalism in classical momentum space. (SL)

Describes some of the atomic age memorabilia which are gathered in an exhibit at the National Museum of History and Technology. (CP)

Demonstrates that investigating coriolis effects in a fixed frame leads to a clearer understanding of the physical nature of the phenomenon. (SL)

Presents and resolves a paradox of the interior region of a closed conducting surface possessing both conduction electrons and muons being shielded from gravity. (SL)
