Know the law Quotes

“God as you probably now know, uses us to do His work. The last time He sent his son, we killed him! We will now have to do the heavy lifting ourselves. We know the Law and we know it's true.”

“Ignorance of the law of irreducibility was no excuse. I could no longer excuse myself with the claim that I didn't know the law -- for knowledge of self and of the world is the law that, even though unattainable, cannot be broken, and no one can excuse himself by saying that he doesn't know it. . . . The renewed originality of the sin is this: I have to carry out my unknowing, I shall be sinning originally against life.”

“Among the many worlds which man did not receive as a gift of nature, but which he created with his own mind, the world of books is the greatest. Every child, scrawling his first letters on his slate and attempting to read for the first time, in so doing, enters an artificial and complicated world; to know the laws and rules of this world completely and to practice them perfectly, no single human life is long enough. Without words, without writing, and without books there would be no history, there could be no concept of humanity. And if anyone wants to try to enclose in a small space in a single house or single room, the history of the human spirit and to make it his own, he can only do this in the form of a collection of books.”

“For many years I have been saying that I would like to write a book (or series of books) called Physics for Mathematicians. Whenever I would tell people that, they would say, “Oh good, you're going to explain quantum mechanics, or string theory, or something like that”. And I would say, “Well that would be nice, but I can't begin to do that now; first I have to learn elementary physics, so the first thing I will be writing will be Mechanics for Mathematicians”. So then people would say, “Ah, so you're going to be writing about symplectic structures”, or something of that sort. And I would have to say, “No, I'm not trying to write a book about mathematics for mathematicians, I'm trying to write a book about physics for mathematicians”; …… it's elementary mechanics that I don't understand. … I mean, for example, that I don't understand this – lever.... Most of us know the law of the lever, but this law is simply a quantitative statement of exactly how amazing the lever is, and doesn't give us a clue as to why it is true, how such a small force at one end can exert such a great force at the other. Now physicists all agree that Newton's Three Laws are the basis from which all of mechanics follows, but if you ask for an explanation of the lever in terms of these three laws, you will almost certainly not get a satisfactory answer.”
