     The Promotion of the Apollo Program

    The success of Apollo was mainly due to the fact that the project was conceived and honestly presented to the public as an international sporting event and not as a contribution to science. The order of priorities in Apollo was accurately reflected by the first item to be unloaded after each landing on the Moon's surface, the television camera. The landing, the coming and going of the astronauts, the exploring of the moon's surface, the gathering of Moon rocks and the earthward departure, all...

     Gravity is Energy

    The laws of thermodynamics decree that each quantity of en^rgy has a characteristic quaUty called entropy associated with it. The entropy measures the degree of disorder associated with the energy. Energy must always flow in such a direction that the entropy increases. Thus, we can arrange the different forms of energy in an "order of merit," the highest form being the one with the least disorder or entropy. Energy of a higher form can be degraded into a lower form, but a lower form can never...

     Humanity is Fortunate to Have a Variety of Energy Sources...

    Humanity is fortunate in having such a variety of energy resources at its disposal. In the very long run we shall need energy that is unpolluting; we shall have sunlight. In the fairly long run we shall need energy that is inexhaustible and moderately clean; we shall have deuterium. In the short run we shall need energy that is readily usable and abundant; we shall have uranium. Right now we need energy that is cheap and convenient; we have coal and oil. Nature has been kinder to us than we h...
