Describes a Fortran program that illustrates how the end-to-end distances in randomly coiled polymer molecules is affected by varying the number and lengths of chains and the angles between them. (MLH)

Describes interactive computer program (listing available from author) which simulates olivine fractionation from basaltic/ultrabasic liquid. The menu-driven nature of the program (for Apple II microcomputer) allows students to select ideal Rayleigh fractionation or equilibrium crystallization. (JN)

Describes one program each for performing Fourier analysis and synthesis with a Hewlett-Packard HP-25 calculator. (MLH)

Describes interactive, geology programs (GEOPACK) for use in geostatistical applications, demonstrations and reviews, and geocartography. Programs, designed for beginning and advanced students, make use of the graphics capabilities of the Apple II microcomputer. (JN)

Reviews three organic chemistry computer programs for TRS-80 and Apple microcomputers. Programs include "Introduction to Organic Chemistry,""Qualitative Organic Analysis," and a game called "Chemrain." Indicates that all three produce a readable screen, require exact responses, use graphics in an appealingly and…

Presented are simple programs in BASIC and FORTRAN to apply the method of least squares. They calculate gradients and intercepts and express errors as standard deviations. An introduction of undergraduate students to such programs in a chemistry class is reviewed, and issues instructors should be aware of are noted. (MP)

Describes the adaption of a simple homogeneous analogue computer for the solution of the Schrodinger wave equations. Photographs of results are included. (CP)

Describes simulated chemistry experiments programed into a Wang 360 programable calculator. Gives data on a sample titration simulation. (TS)

This software review focuses on five concept-related packages of programs in the Apple version and are viewed as well-written in terms of both educational sophistication and programing expertise. (MP)

Presents three activities: (1) the investigation of the purity and stability of nicotinamide and flavin coenzymes; (2) desk-computer fitting of a two-exponential function; and (3) an interesting and inexpensive solubility product experiment for introductory chemistry. (RH)
