Summarizes results of a survey that examined 13 textbooks claiming to use SI units. Tables present data concerning the SI and non-SI units actually used in each text in discussion of fluid pressure and thermal energy, and data concerning which texts do and do not use SI as claimed. (CS)

Describes physics formulas which can be used by law enforcement officials to determine the possible velocity of vehicles involved in traffic accidents. These include, among others, the slide to stop-level road, slide to stop-sloping roadway, and slide to stop-two different surfaces formulas. (JN)

Deals with the conversion of electronic hand calculators to timing devices. This article illustrates a conversion of a rather versatile calculator by means of simple and inexpensive circuitry. (HM)

Included is information regarding: the adaptation of microcomputer materials in physics curricula; a school-industry liaison case study involving basic electronics for teachers; the use of language in science lessons; problems in teaching image-synthesis skills; and tabulated results of a questionnaire concerning a ten-year span of organic…

Reviews six new children's science books: one on mathematics and five on topics related to physics. (GT)

A scientist explains how commercial smoke detectors work. (BT)

Examining the reading level of two series of high school physics texts widely used between 1954 and 1976, this study indicates that the reading level of these two texts did increase during the 1960s while at the same time there was a decline in overall reading ability as reflected by SAT scores. (JC)

A discussion of the periodic table of the elements and the role it has played in the synthesis of man-made elements. (BB)

Reviews Einstein's main contributions to physics, and analyzes the importance of a coherent body of theory. Einstein's involvement in nonscientific issues such as nuclear disarmament is also included. (HM)

Describes and evaluates the Tel-X-Ometer, its performance, and its accessories. The apparatus, with its low intensity x-ray beam, is specifically designed to make x-ray experiments safe, practical, and affordable for the students. (GA)

Discusses new experiments that are being designed to solve the solar neutrino problem and determine the power source of the sun. (HM)

Discusses research, legislation, exploration efforts, and pricing data concerning uranium. (MLH)

Describes the six types of testing used in the Nuffield A-Level physics exam in Great Britain. Includes numerous item examples and discusses changes that have been made in the exam. (MLH)

Describes the 0-level Nuffield physics exam used in Great Britain and procedures for administering this exam. (MLH)

Presents the most important features of observational astronomy, including the motions of the sun and the moon and the methods by which eclipses can be predicted. (MLH)
