This paper examines the equivalence of two construct-a-concept-map techniques. construct-a-map with created linking phrases (C) and construct-a-map with selected linking phrases (S). The former places few constraints on the respondent and has been considered the gold standard; the latter is cost- and time-efficient. They are compared in terms…

This textbook presents elementary principles of mechanics, hydrostatics, hydraulics, pneumatics, acoustics, pyronomics [sic], optics, electricity, galvanism, magnetism, electromagnetism, magneto-electricity, and astronomy. Among topics covered are descriptions and illustrations of McCormick's reaper, Sharps' Rifle, printing presses, House's…

This textbook is a course in natural science and astronomy. The contents include mechanical properties of bodies; mechanics of solids; mechanics of fluids; nature and production of sound; nature and transmission of light; excitation and characteristic effects of electricity; properties and magnets; theoretical astronomy; and descriptive astronomy.

Presents theoretical fundamentals of sideways forces exerted on a cricket ball, an aerofoil, and a yacht, involving the properties of boundary layers and a description of velocity and circulation. (CC)

Compares the features and the philosophy underlying the "bookstrap" model of strongly interacting particles with the concepts of Mahayana Buddhism. Indicates that a study of Eastern ideas might lead to the new viewpoint necessary for the future development of the hadron physics. (CC)

Uses the format of a dramatic play as a means of explaining the relativity of time to beginning physics students. (JR)

Discusses the problem of gravity as it relates to distance from the center of the earth, and reports contradictory explanations from different source books. Uses this example to illustrate that science should not be taught from a single source, such as a textbook. (JR)

A laboratory experiment is detailed which students can themselves perform to illustrate the subtleties of Einstein's theory of relativity. (JP)

Discusses the technology used for transduction between electrical and acoustical signals. In particular, the recent developments in microwave ultrasonics research are presented. (JP)

Reviews the Hafele-Keating experiment on relativistic changes in eastward and westward moving cesium atomic clocks. Recommends the use of the Sagnac effect to remove the east-west time asymmetry and of the general-relativistic effect to elucidate the clock-rate changes. (CC)

Discusses and explains the phenomenon of superconductivity and examines the properties of superconductors. (JR)
