This course, offered by the departments of chemical engineering and polymer science and engineering at the University of Massachusetts, is mainly a course in applied fluid dynamics with an emphasis on flow pressures dominated by viscous effects. (BB)

A new freshman chemical engineering course at the University of Texas emphasizes the development of writing skills. (BB)

Exercises are presented for classification of marine algae on the basis of biochemical characteristics such as pigmentation, cell wall components, and food storage products. (BB)

An approach is described for the incorporation of technical writing instruction into a chemistry course for college seniors. The approach uses a guide to technical writing and one or two lectures. (BB)

Discusses the use of individualized instruction, known as the personalized system of instruction (PSI), in teaching college physical science courses. Tables summarizing the advantages and disadvantages of PSI from the viewpoints of students, teachers, and administrators are presented. (HM)

Describes how the art of Maurits Escher can be used in physical science and general chemistry classes. A film depicting Escher at work in creating a woodcut and a set of slides are shown to college students. The students are encouraged to observe and record what they see. (HM)

Presents a computer method for teaching chemical equilibrium concepts using material balance conditions and the minimization of the free energy. Method for the calculation of chemical equilibrium, the computer program used to solve equilibrium problems and applications of the method are also included. (HM)

Presents an undergraduate physical chemistry laboratory experiment describing the measurement of the proton magnetic resonance spectra. (HM)

Describes the development and operation of a college biophysics course as well as the educational materials used, the structure of the modules and the performance of the students. Also discusses the economics of such a flexible system of instruction. (GA)

Describes a simple recursive method for calculating the partition function and average energy of a system consisting of N electrons and L energy levels. Also, presents an efficient APL computer program to utilize the recursion relation. (Author/GA)

Describes the development of physics courses at the Open University, system of instruction, use of television, summer school, tutorials, and the costs involved. (GA)

Describes a summer workshop course in rocketry offered to educators and sponsored by industry. The participants built various model rockets and equipment and worked on challenging practical problems and activities. (GA)

Describes an experiment for the measurement of the reflectances of dielectric surface. The experiment is analyzed in terms of the Stokes parameters and the Mueller calculus, and Malus law is derived. The experiment also provides an introduction to the properties of real linear polarizers. (Author/GA)

Describes an experiment in which a point source of light, when viewed through a cylindrical tube having reflecting inner walls, appears as a series of sharply defined rings, due to the multiple reflections from the inner walls of the tube. ( GA)

Shows that when positions annihilate in solid materials the energy distribution of the annihilation gamma rays is much broader than that of a 0.511-Mev gamma peak. This broadening is caused by the momentum distribution of the electrons in the material. (Author/GA)
