Discusses the great dependence of the present arms race on a healthy physics enterprise and the pervasive connections between pure and applied science and military needs. This discussion is intended to orient college students about some problems directly related to progress made in science. (HM)

Describes a method to form on a large fixed screen the succession of the diffraction patterns on the different infinity. This method is designed to be used in a college physics course. (HM)

Presents the philosophy and mechanics of a professionally oriented astronomy laboratory for nonscience majors. Design of the laboratory, description of the exercises, and the results of using this approach at the University of Kansas are also described. (HM)

Presents the results of the evaluation of a self-paced freshman physics laboratory and its assessment procedures used in the first-year physics course at the University of Adelaide, South Australia. (HM)

Discusses the possible dangers of the educational radioactive sources used in a college physics laboratory. The discussion is intended to increase the awareness of teachers and students. (HM)

Presents details of anodic stripping analysis (ASV) in college chemistry laboratory experiments. Provides block diagrams of the analyzer system, circuitry and power supplies of the automated stripping analyzer, and instructions for implementing microcomputer control of the ASV. (CS)

Details the benefits of the development and maintenance of useful work activities, such as "co-op" or "internship" programs, for chemistry students who wish to acquire some understanding of the requirements of the industrial job market as they complete their college education. (CS)

Describes a first-year chemistry experiment that illustrates the fundamental concepts of a photoinduced reaction. Qualitative and quantitative parts of the photoreduction of potassium ferrioxalate are detailed. (CS)

Describes an advanced level experiment in which a transition metal cluster compound, cyclopentadienylcarbonyliron tetramer, is synthesized and characterized spectroscopically. Its redox properties are then explored through cyclic voltammetry. (CS)

The origins of academic chemistry are described and the author's views on the future of university academic chemistry are presented. (HM)

Discusses several different methods that performers (divers and trampolinists) use to initate somersaults and twists and presents concrete examples of each method. Presents and evaluates quantitative calculations using information about the moments of inertia, mass, etc., of "typical" performers. (Author/GA)

Using a photon-counting technique, finds the angular distribution of emitted and detected power and the total radiated power of an arbitrary moving source, and uses the technique to verify the predicted effect of the earth's motion through the cosmic blackbody radiation. (Author/GA)

Presented is a new proof of the uncertainty relation for wave functions that are absolutely integrable and have absolutely integrable Fourier transforms. (Author/GA)

The author argues that a Lagrangian that yields equations of motion for a damped simple harmonic oscillator does not describe this system, but a completely different physical system, and constructs a physical system that the Lagrangian describes and derives some of its properties. (Author/GA)

The author reviews some of the chemistry of scandium and indicates the problems associated with its classification. (Author/GA)
