The physics of vertical jumping is described as an interesting illustration for motivating students in a general physics course to master the kinematics and dynamics of one dimensional motion. The author suggests that mastery of the physical principles of the jump may promote understanding of certain biological phenomena, aspects of physical…

Presents the history of the discovery of pulsars, observations that have been made on pulsar radiation, and theories that have been presented for its presence and origin. Illustrations using pulsar's properties are presented in mechanics, electromagnetic radiation and thermodynamics. (DS)

Surveys the responses given to a physics problem regarding calculations of the temperature difference between the internal and external surfaces of a pan with boiling water. Presents a numerical answer to the problem. (DS)

Reports a verification that hot water begins to freeze sooner than cooler water. Includes the investigations that lead to the conclusions that convection is a major influence, water content may have some effect, and the melting of the ice under the container makes no difference on the experimental results. (DS)

Presents a general review of current practical applications of the properties of superconducters. The devices are classified into groups according to the property that is of primary importance. The article is inteded as a first introduction for students and professionals. (Author/DS)

The theory of canonical transformations and its development are discussed with regard to its application to Hutton's principle. Included are the derivation of the equations of motion and a lack of symmetry in the formulaion with respect to Lagrangian and the fundamental commutator relations of quantum mechanics. (Author/SA)

Examines the characteristics of the evolving processes of technology as well as those which precede the birth or worldly appearance of the technological product. (Author/RK)

Endorses John L. Rudolph's argument that the time spent on "the nature of science as a thing-in-itself" is less than the time spent "seeking greater consensus about what social function we wish our image of science to serve". Focuses on Dewey's and Schwab's ideas to discuss the function and practice of science education. (Contains 14 references.)…

Explains methodological naturalism in science education and describes problems related to it when the real nature of science is considered. (YDS)
