A study was devised to determine whether, if color is found superior to black-and-white for communicating dynamic picture content, that superiority can be attributed to the realism of authentic color, or whether that superiority is the effect of the simple presence of color. A sample of 90 sixth grade students were shown slides, half of which…

Most studies involving cinematographic analyses acknowledge the work of late 19th-century cinematographers and review current literature, but the significant "middle generation" of cinematographers are deleted. The contributions of Wallace O. Fenn, Herbert O. Elftman, Ruth B. Glassow, Ernst Jokl, and Thomas K. Cureton are highlighted.…

This study investigated the functions of the sartorius and tensor fascia latae muscles through electromyography using fine-wire electrodes. (RC)

A chart lists types of mechanical motion with mathematical formulas describing acting force, direction of force, velocity, acceleration, and path traversed. (JH)

Discusses the various views on Galileo's demonstration of free fall. Cites several historians' accounts of early free fall experiments and Galileo's contributions to knowledge in this area. (TS)

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…

The change in man's conception of the world, and particularly the problem of motion, is reflected in the changing images used by the poets who lived through the scientific revolution. (Author/TS)
