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)

Discusses the theory of behaviorism from a psychological perspective. Three issues are addressed: (1) the datum, including human verbal behavior; (2) the behavior stream; and (3) reduction, including a scientific viewpoint. (Contains two references.) (LRW)

The study of education does not lend itself well to an experimental approach. Educators cannot even agree on a fixed body of common knowledge constituting a discipline of education. Education is subjective, lacking governing equations, unifying principles, and invariant experiments. Education must be dealt with in words, with feelings, and from a…

Argues that history and philosophy of science can investigate scientific questions that are excluded from science itself by working as a shadow discipline, complementing the specialist science in the production of knowledge about nature. Contains 16 references. (Author/WRM)

Introduces the notion of culturalizing science instruction--making the values enacted in science teaching and the resulting contexts explicit. In contrast to the possibility of value-free instruction implied in the philosophy level of Baptiste's typology, a premise of culturalizing science instruction is that curriculum is taught in a way that…

Attempts to ascertain whether the presence of biasing values in the practice of science is an inbuilt feature of an idealized institution, Science, and judges that those values inbuilt to Science are not a source of bias. (Author/MM)

Analyzes how Thomas Kuhn's writings are used by others, especially science education researchers. Examines who cites Kuhn, in what manner, and why. (Author/CCM)
