A frequency analysis was used to tag cortical activity from imagined rhythmic movements. Participants synchronized overt and imagined taps with brief visual stimuli presented at a constant rate, alternating between left and right index fingers. Brain potentials were recorded from across the scalp and topographic maps made of their power at the…

The time of flight, range and the angle which maximizes the range of a projectile in a linear resisting medium are expressed in analytic form in terms of the recently defined Lambert W function. From the closed-form solutions a number of results characteristic to the motion of the projectile in a linear resisting medium are analytically confirmed,…

A model for car following on a closed loop is defined. The stability of the solutions of the model is investigated by considering the evolution of the roots of the corresponding characteristic equation in the complex plane. The solution provides a motivation for investigating the behaviour of the roots of a simple class of algebraic equation.…

Since Robert Millikan discovered the quantization of electric charge and measured its fundamental value over 90 years ago, his oil-drop experiment has become essential in physics laboratory classes at both the high school and college level. As physics instructors, however, many of us have used the traditional setup and experienced the tedium of…

The leap of a grasshopper is used as an introduction to the capabilities of muscle, using Newton's laws of motion and other standard equations as the basis of the study. (Author/PEB)

The study tested the prediction that enforced sensory motor sets results in longer reaction and movement times than does enforced sensory set (concentrating on the stimulus). (Author/JA)

This study examined the mode of locomotion preschoolers used to traverse fence-like barriers of various heights in order to reach a goal. Preschoolers could step over the barrier, crawl under it, or walk under it. The experimental situation consisted of a room with four fences set up at different heights. Two age groups of preschool children…

An algebraic definition of time differentiation is presented and used to relate independent measurements of position and velocity. With this, students can grasp certain essential physical, geometric, and algebraic properties of motion and differentiation before undertaking the study of limits. (Author)

This article discusses how the Eastern tradition of inwardness and unification is an important lesson for Western education in the arts. (JS)

Article developed from remarks made to the University of Illinois Institute for Advanced Study in Aesthetic Education held in the summer of 1967.

The angular momentum of a human body derived from both the angular velocity and angular displacement, utilizing cinematographic records has not been adequately assessed, prior to this study. Miller (1970) obtained the angular momentum but only during the airborne phase of activity. The method used by Ramey (1973) involved a force platform, but…

This is a short paper about turns in skiing. It contrasts early and contemporary techniques and discusses biomechanical studies of rotation of limbs. It is stated that individual people's builds partially determine how they will accomplish turns. Diagrams are included. (CD)
