Today we say that the law of relativity is supposed to be true at all energies, but someday somebody may come along and say how stupid we were.Richard Feynman
The thing that doesn't fit is the thing that's the most interesting: the part that doesn't go according to what you expected.Richard Feynman
The universe is very large, and its boundaries are not known very well, but it is still possible to define some kind of a radius to be associated with it.Richard Feynman
There is nothing that living things do that cannot be understood from the point of view that they are made of atoms acting according to the laws of physics.Richard Feynman
Because the theory of quantum mechanics could explain all of chemistry and the various properties of substances, it was a tremendous success. But still there was the problem of the interaction of light and matter.Richard Feynman
Working out another system to replace Newton's laws took a long time because phenomena at the atomic level were quite strange. One had to lose one's common sense in order to perceive what was happening at the atomic level.Richard Feynman
We do not know what the rules of the game are; all we are allowed to do is to watch the playing. Of course, if we watch long enough, we may eventually catch on to a few of the rules. The rules of the game are what we mean by fundamental physics.Richard Feynman
Because atomic behavior is so unlike ordinary experience, it is very difficult to get used to, and it appears peculiar and mysterious to everyone - both to the novice and to the experienced physicist.Richard Feynman
I think equation guessing might be the best method to proceed to obtain the laws for the part of physics which is presently unknown. Yet, when I was much younger, I tried this equation guessing, and I have seen many students try this, but it is very easy to go off in wildly incorrect and impossible directions.Richard Feynman
It has been discovered that all the world is made of the same atoms, that the stars are of the same stuff as ourselves. It then becomes a question of where our stuff came from. Not just where did life come from, or where did the earth come from, but where did the stuff of life and of the earth come from?Richard Feynman
