No one knows what he himself is made of, except his own spirit within him, yet there is still some part of him which remains hidden even from his own spirit; but you, Lord, know everything about a human being because you have made him...Let me, then, confess what I know about myself, and confess too what I do not know, because what I know of myself I know only because you shed light on me, and what I do not know I shall remain ignorant about until my darkness becomes like bright noon before your face.
[Max Planck] was one of the finest people I have ever known... but he really didn't understand physics, [because] during the eclipse of 1919 he stayed up all night to see if it would confirm the bending of light by the gravitational field. If he had really understood [general relativity], he would have gone to bed the way I did
A cannonball travels only two thousand miles an hour; light travels two hundred thousand miles a second. Such is the superiority of Jesus Christ over Napoleon.
But I reckon I got to light out for the Territory ahead of therest, because Aunt Sally she's going to adopt me and sivilize me, and I can't stand it. I been there before.
It followed from the special theory of relativity that mass and energy are both but different manifestations of the same thing - a somewhat unfamiliar conception for the average mind. Furthermore, the equation E = mc², in which energy is put equal to mass, multiplied by the square of the velocity of light, showed that very small amounts of mass may be converted into a very large amount of energy and vice versa.
I would paint a portrait which would bring the tears, had I canvas for it, and the scene should be -- solitude, and the figures -- solitude -- and the lights and shades, each a solitude.
All knowledge, the totality of all questions and all answers, is contained in the dog. If one could but realize this knowledge, if one could but bring it into the light of day, if we dogs would but own that we know infinitely more than we admit to ourselves!
It is the essence of truth that it is never excessive. Why should it exaggerate? There is that which should be destroyed and that which should be simply illuminated and studied. How great is the force of benevolent and searching examination! We must not resort to the flame where only light is required.
There is no finer way to demonstrate love of God than by serving Him in the positions to which we may be called. Occasionally, the reward for that service will be prompt, and we'll see the light in the eyes of the person whom we have helped. Other times, however, the Lord will let us wait a little while and let our reward come another way.
The human race will disappear. Other races will appear and disappear in turn. The sky will become icy and void, pierced by the feeble light of half-dead stars. Which will also disappear. Everything will disappear. And what human beings do is just as free of sense as the free motion of elementary particles. Good, evil, morality, feelings? Pure 'Victorian fictions'. Only egotism exists.
