Construction of a laboratory area suitable for laser experiments and the creation of holograms is described. (CP)

If the scientists working on the Manhattan Project had realized the consequences of the atomic bomb earlier, formulated their recommendations more precisely, and approached the statesmen in time, American policy on use and control of the bomb might well have been different. (Author/BT)

Lists changes which have been made in second edition and explains the philosophy upon which the alterations were based. (CP)

Lists advantages of combining physics and chemistry into a three year physical science course. Cites increase in teacher morale and decrease in student disciplinary problems as two important results. (CP)

Describes a laboratory experiment on geometrical optics designed for life science majors in a noncalculus introductory physics course. The thin lens equation is used by the students to calculate the focal length of the lens necessary to correct a myopic condition in an optical bench simulation of a human eye. (Author/MLH)

Discusses the principle of operation of phase-sensitive amplifiers. Gives three examples, suitable for undergraduate laboratory use, of the use of phase-sensitive, or "lock-in" amplifiers. Concludes with a description of an inexpensive lock-in amplifier which has an overall voltage gain of 1000. (Author/MLH)

Reports on a one day conference on experimental physics in school and university. States opinions of some of the participants who felt that practical rather than theoretical work should be stressed. (CP)

Analyzes some of the possible causes for the low popularity of high school physics, including tough grading practices, the fact that physics is required more often than it is elected, the practice of teaching physics by lectures, and the lack of a methodology in teaching abstract concepts. (MLH)

The author recognizes a body of basic knowledge in nuclear power plant technoogy that can be taught in school programs, and lists the various courses, aiming to fill the anticipated need for nuclear-trained manpower--persons holding an associate degree in engineering technology. (Author/BP)

Describes an experiment that generates data for calculating the ratio of molecular separation in a gas to molecular diameter. (GS)

Describes a course for college seniors, science majors and non-majors, designed to trace the development of modern science as part of western culture. Reports three years of experience. An outline of the course and a reading list are included. (GH)

Describes a variety of experiments and activities such as refractive index by an interference method, Young's third slit, a microscope problem, uses of a hand stroboscope, an acceleration game, an aluminum thermometer, why milk boils over, and others. (BR)
