This booklet on sprinting is divided into four chapters. Chapter 1 "Introduction," provides an analysis of the 100-meter dash, summarizes world records, and discusses the reliability of timing the sprint race. Chapter 2, "Describing the Sprinter," discusses the following topics: anatomical characteristics, flexibility, reaction, strength/power,…

Two hundred and fifty-six children between the ages of five and eight years were tested for reaction time and movement time on an electrical device which was constructed by the author. Since the primary purpose of this project was to gather base-line data on the reaction times and movement times of these particular children, no specific…

This monograph was written for the Conference on the New Instructional Materials in Physics, held at the University of Washington in summer, 1965. The measurement of very small distances and sizes, and the concept of models are discussed in the introduction. The optics of slits is dealt with in chapter 2. Chapter 3 presents the optics of holes.…

Provides a physical description of motion resulting when force is applied perpendicular to the axis of rotation on a gyroscope. (SL)

Learning how to create smooth animation on the computer is a two-step process. Step one (discussed in SE 539 133) involves creating shapes. In the second step, students animate their newly created shapes. The programing necessary to accomplish the animation is discussed. (JN)

Two studies investigated three- and five-month-old infants' ability to discriminate and recognize different motions of rigid objects. Also explored was the nature of stimulus information which makes such discrimination and recognition possible. The results are discussed in terms of disruptions in the optic array. (Author/DST)

Data on motions involved in kicking a football were subjected to multiple regression analysis to ascertain the kinesiologic determinants of the foot's arcing motion. (GW)

No one has ever been able to look into the language space, nor has anyone been able to measure the phenomenon of consciousness without the interference of an observer. This article changes the situation, showing that from now on it is possible to produce measures of consciousness without the presence of classical observation devices. The…

Describes ways to reduce energy consumption in transportation, space heating, and air conditioning. Greater efficiency for energy use from an engineering point of view is possible in present circumstances. (PS)

Presents the third of a series of articles on symmetry. Describes the symmetry properties of molecules in translatiional and rotational motion. Presents these dynamic symmetry properties in character tables for five point groups. Supplements the article with more rigorous material involving spectroscopic states, degenerate point groups and…

Cohesion and gravitational force are given as the mechanisms by which the siphon works. Hydrostatic theories and experimental results are given to support this conclusion. (TS)

Describes a laboratory activity about measurement and its reliability for general education students. The measurement focuses on automobile speeds and allows for estimates of errors, experimental design, and relativity in addition to kinematical concepts. (DS)
