4. Dream Life

Again I should like to start with a comparison. From the history of science you will know that Newton, the English physicist and natural philosopher, established the theory of what is called gravitation—the effect of weight in universal space. He extended this law, illustrated in the ordinary falling of a stone attracted by the Earth, to the reciprocal relation between all bodies in the Cosmos. He stated also that the strength of gravity diminishes with distance. For any physicists who may be present I will remind you of the law—gravity decreases with the square of the distance. Thus if the distance doubles, gravity becomes four times weaker, and so on.
