Described is an astronomy program at Moorhead State College (Minnesota) for liberal arts students. Facilities and equipment and factors related to the program's success are discussed. Suggestions to others who may want to develop such programs are given. (Author/RH)

Reports the use of a heavy duty hacksaw blade and a 1000 turn pick-up coil to form the basis of a mechanical oscillator for a laboratory exercise in mechanical resonance designed for either the elementary undergraduate course or in association with an upper level mechanics course. (LZ)

Some specific difficulties and pitfalls frequently encountered by beginning students in quantum mechanics relating to pure states, mixtures, and polarization are emphasized and clarified. (Author/CP)

A practice-teaching program directly related to a physics course for future elementary school teachers has been developed at the University of Washington. Described are some of the activities and the benefit of the activities to both the prospective teachers and the physics department. (RH)

Develops a geometric solution to be used with spatial integrals needed for finding electric and magnetic fields. The method is used in the calculation of the electric fields due to a uniformly charged plane, line and sphere. (CP)

Describes a four-year baccalaureate physics program which provide preparation for specialized graduate work in medical physics. (SL)

Describes analogs of abstract concepts of elementary particle physics. (SL)
