Reviews are presented which are designed for beginning undergraduates. The films are divided into two series: (1) Manipulation of Liquids and Solids, and (2) Chromatographic Separations and Spectorscopic Methods. Topics increase in complexity from one film to the next. (DF)

Describes a new method for teaching the Second Law by way of the Carnot cycle. The two features of this method are that the isothermal process is considered first to establish some basic concepts, and then the nonisothermal cyclical process is introduced. (CS)

Presents a mathematical treatment of optical propagation in crystals as an eigenvalue problem involving a real symmetrical dyadic. (MLH)

Shows that local equilibrium and energy considerations in an elastic dielectric crystal lead to a simple derivation of the Maxwell stress tensor in anisotropic dielectric solids. The resulting equilibrium stress-strain relations are applied to determine the deformations of a charged parallel plate capacitor. (MLH)

Advances new explanations for false observations made during 1903-1906 concerning a spurious radiation called N rays. (MLH)

Discusses the first known preparation of oxygen by Cornelis Drebbel, and the escape by Neils Bohr to England upon Nazi occupation of Denmark. (MLH)

Gives evidence for hydration effects as the cause of the dependence of DNA's buoyant density on the percent composition of its guanine and cytosine bases. (MLH)

Presents a classical approximation of the equipartition theorem of thermodynamics. A canonical distribution is assumed and the calculations of Reif are followed to solve for the average potential energy per particle. (CP)
