Describes an easy-to-use set of computer programs for the generation of multiple-choice and essay examinations in an introductory astronomy course. Program enables the user to establish files of test questions and to rapidly assemble printed copies of examinations suitable for photocopying. (Author/GS)

Presents a ray-tracing procedure based on some ideas of Herzberger and the matrix approach to geometrical optics. This method, which can be implemented on a programmable pocket calculator, applies to any conic surface, including paraboloids, spheres, and planes. (Author/GA)

Discusses what is meant by a linear program and states and illustrates two of the theorems upon which the methods of linear programing rest. This description is intended as an introduction to linear programing of physics students. (HM)

Describes how certain concepts basic to electron optics may be introduced to undergraduate physics students by calculating trajectories of charged particles through electrostatic fields which can be evaluated on minicomputers with a minimum of programing effort. (Author/SA)
