Discusses the use of a balance assembled from standard laboratory components to conduct an experiment on the repulsion between two bar magnets. Includes an analysis of data on the two-pole and four-pole models. (CC)

An attempt to empirically test conflicting hypotheses on whether scientific discoveries are the result of research by many or few scientists. The data, drawn from physics, supports the hypothesis that physicists making important discoveries depend on the research of a relatively small number of scientists. (Author/JB)

The history of the short film and the single concept film loop is presented. Lists fourteen reasons why it may be necessary to make and use a film loop. Film loop projectors are analyzed according to present features and deficiencies with predictions on future improvements. (DS)

Research review is conceptualized as a scientific inquiry involving five stages that parallel those of primary research. The functions, sources of variance, and potential threats to validity associated with each stage are described. (Author/PN)

Various phenomena in chemistry and biology can be understood through Gibbs energy utilization. Some common phenomena in chemistry are explained including neutralization, hydrolysis, oxidation and reaction, simultaneous dissociation equilibrium of two weak acids, and common ion effect on solubility.
