Develops a simple model of radio wave propagation and illustrates how basic physical concepts such as refractive index, refraction, reflection and dispersion can be applied to a situation normally not met in introductory physics courses. (Author/GA)

Several teachers from State College (Pennsylvania) Area School District became intrigued with helping their students better understand the science associated with a unit on air and aviation. In particular, they observed that students often encountered difficulty with abstract flight concepts, such as lift, thrust, and drag. Content issues became…

Presents a chapter from an introductory college-level astronomy textbook in which full-color photographs and numerous diagrams highlight an extensive description of the planet Jupiter. Topics include Jupiter's geology, rotation, magnetic field, atmosphere (including clouds and winds), and the Great Red Spot. (DH)

Presents programmable calculator solutions to selected problems, including area moments of inertia and principal values, the 2-D principal stress problem, C.G. and pitch inertia computations, 3-D eigenvalue problems, 3 DOF vibrations, and a complex flutter determinant. (SK)

Describes how model rocketry can be a useful educational tool at the university level as a practical application of theoretical aerodynamic concepts and as a tool for students in experimental research. (BR)

An open letter to youth in which future opportunities in the space sciences are outlined. (MLH)

Presents a summary of the Reports of the Panels'' published by the Astronomy Survey Committee of the National Academy of Sciences in 1973, involving aspects of cosmology, quasars, exploding galaxies, stars, stellar evolution, solar system, organic molecules, life, and interstellar communication. Included are recommendations for scientific…

The results of an opinion questionnaire sent to the personnel directors of 28 domestic airlines indicate that the majority of the respondents feel that an aviation minor would be valuable to prospective airline employees. Includes comments on what subject areas the respondents feel would be important in an aviation minor. (MLH)

Describes a course, without laboratory, using rudimentary algebra and covering such topics as gravitation, orbital mechanics, atomic structure, geomagnetism, electromagnetic spectrum, theory of relativity, extraterrestrial life, and interstellar travel. (GH)

This document presents an overview of knowledge gained from the scientific explorations of the moon between 1969 and 1972 in the Apollo Program. Answers are given to questions regarding life on the moon, surface composition of rocks on the moon, the nature of the moon's interior, characteristics of lunar "soil," the age, history and…

"Space Handbook" is used as the text for the Fundamentals of Space Operations Course of the Air University Institute of Professional Development, Maxwell Air Force Base, Alabama. The text familiarizes the student with basic physical laws and these aspects of aerospace science as indicated by chapter titles: The Space Environment; Orbital…

Describes an experiment in which a college student learned flight principles on a flight simulator, then flew an actual plane with no need for assistance from the accompanying instructor. (MLH)

Describes a dynamical system which is stable at potential maxima. The maxima, called L-4 and L-5, are stable locations of the restricted three-body problem. Energy loss from the system will tend to drive it away from stability. (GA)

Describes a senior level aerospace engineering course converted to the Personalized System of Instruction (PSI) to counter problems presented by declining enrollment. (SL)
