Describes a physics laboratory experiment for nonscience majors intended to illustrate indirect experimental methods of sciences treating objects too small for sensory observation. The student explores and attempts to identify an object in a closed container, using provided experimental tools and small openings in the opaque lid. (MLH)

Describes effects which produce the semidiurnal tidal bulges, using elementary methods, without reference to fictitious forces and without recourse to a potential. (Author/HM)

Discusses the two-capacitor problem by considering the self-inductance of the circuit used and by determining how well the usual series RC circuit approximates the two-capacitor problem when realistic values of L, C, and R are chosen. (GA)

Describes an interactive computer program which allows students to perform simulated quantum measurements on a one-dimensional harmonic oscillator. (SL)
