Reviews the biomechanical processes presented in the preceding programs. Relates these concepts to the way in which all forms of life are linked and resembles each other. Concludes by offering an answer to the question "How did life begin?"
Physicists and biophysicists find common ground in interpreting the oscillation of a suspended spring. It is a simple piece of coiled metal which pulses over a small pool of mercury. The spring and the mercury are connected to a battery. Both scientists agree that the motion, regular and seemingly tireless, results from a design embodying the principle of “positive feedback.” From the biophysicist’s point of view, the pulsing spring is rather like the beating human heart. More and more areas of agreement common to all branches of science thus seems, as Professor LeCorbeiller puts it, “too beautiful not to be true.” And if science is one in revealing nature, will it not demonstrate that nature itself is one … animate and inanimate, spring and heart, body and tone?

This program goes into the peculiar problem of weightlessness, which is typical of space flight, when the speed of the vehicle on an elliptical orbit around the earth counteracts the attraction of gravity and the occupants cease to have any weight. Maj. Stallings, who flies a jet plane in weightlessness experiments at the School of Aviation Medicine, explains the technique of performing this maneuver; the only way known to secure the effect of “zero gravity” within the earth’s atmosphere. Dr. Gerathewohl then describes some of the results of the flights on subjects in research which he has carried on at the School for several years.

Pumping of propellants and cooling of the motor were two major problems that were solved. Since the collapse of Germany, the V-2 has been used in several novel experiments.

The skirmishes at Lexington and Concord and even the more determined fighting around Boston were only meant to show the mother country that the colonials were serious in their demand to be treated fairly as Englishmen. But then events moved rapidly. In July, 1776, the die was cast and the challenge thrown in the face of the British. The next years were full of heartbreaks and setbacks. Almost to the end, the outcome of the struggle was in serious doubt. While the war was on, the new nation often found distressing troubles of an internal nature. The independence for which the fight was being waged at times seemed to be anything but that sweet thing glimpsed in the dreams of freedom. But in the end, victory came to the Americans. In 1783 Great Britain officially recognized the United States of North America. The introductory chapters of the American story were concluded. The main chapters were to follow.
