In reviewing the events of the advances of science and technology of the past two decades one is struck by the magnificence of man's accomplishments. The first moon walk televised live in 1969, the widespread utilization of color television receivers, the educational uses of sophisticated audio-visual equipment such as overhead projectors, slide projection, sound tape recorders, close-circuit television and videotape and the almost omniscient usage of television, is ample evidence to demonstrate that the tools necessary to accomplish a task are readily accessible items in this age. We are introduced to new gadgets, innovations, and events (like the moon walk) at such a rapid pace that we have become more flexible and more receptive to change; so much so that at times many of us are even blase about nearly miraculous accomplishments.
