摘要:
The goals of a science course for nonscience students can be adequately met with an astronomy course which is also suitable for science majors. The replacement of the survey approach by the topical approach in the course provides greater coherence and meaning for the information presented. A specific set of topics is presented and evaluated in relation to the goals of an astronomy course for nonspecialists.

摘要:
An elementary laboratory experiment is described for obtaining the value of the velocity of light from two or more stellar spectrograms using the Doppler effect and the concepts of relative motion.

摘要:
At Texas A&M University we have developed a course designed to relate to people with interests in fields not closely associated with physics. We hope that the content and technique described in this article may provide some helpful guidelines for teachers who are now developing or who are considering developing similar courses.

摘要:
A classroom dialog form is used for a discussion of the question “What is reality?” It is agreed that a concept of reality which goes beyond immediate experience of phenomena is required. Empirical confirmation of expected properties is proposed as a reality criterion for physics. An allegation of falseness of physicists' reality concepts is made, with assertion of inadequacy for experiences of most people. A partial resolution is found in possible eventual description by a basic physical science. However, individuality among human beings suggests a role for humanists that is irreducible to that of scientists. Although the success of mathematics in physics supports a view that nature is essentially mathematical, the nature of mathematics and its comparative lack of success in some branches of science lead to a contrary position. A further argument is made from quantum physics that the inability of quantum theory to predict individual events argues against a completely mathematical character of physical reality. There is an analogy with individuality in human behavior, even though present-day science gives no information of connection. Mathematical properties are notable for a large domain of natural phenomena, but with apparent barriers to unlimited extension, in favor of fluctuation and diversity.

摘要:
An alternative to the lecture format for teaching junior and senior level material is outlined. The basis of this alternative is the widely used Keller plan which features self-pacing, personal attention for each student, and emphasis on mastery of specific learning objectives. To meet needs particular to upperclass students and to create a learning atmosphere more appropriate for “pre-professionals,” we have added the following features: (1) student freedom in selecting his own procedure (textbook readings, exercises, etc.) for mastering the course material, and (2) some variety in topics studied by each individual student. Two successful trials of this adapted Keller plan in an atomic physics course at MIT are described, with emphasis on student performance and the administrative structure of the new format.

摘要:
In the current era of decreasing support and increasing administrative accountability it is noted that measurable objectives are increasingly being required. The nature of accomplishable objectives is examined, and a list of behavioral teaching objectives for a liberal arts general physics laboratory is presented. The list includes minimum performance levels and illustrations as currently advocated by educators. The objectives are suggested on the basis of two arguments: first, that they provide a rationally sound basis for the selection of laboratory content, and second, that they are stated in the form that is currently being accepted by administrators and accountability experts.

摘要:
A new course, in which the relationship of scientist to humanity as well as to science is investigated, is described. A selection of student reactions to the initial offering of the course is presented, and the possible role of the course in science education is discussed.

摘要:
A demonstration of the motion of electrons in atoms is described. The demonstration is provided by measuring the Doppler shift of gamma rays scattered by the moving electrons. Scattering materials ofCH2,aluminum, brass, and lead were used; the scattered gamma ray spectra clearly show the differences in the electron velocities in these materials.

摘要:
Potential energies are found for which the stationary-state motion of a particle in a static force field is the same according to the Schrödinger equation as in classical mechanics.
