Maybe that is why young people make success. They don't know enough. — Richard P. Feynman Copy Share Image
When you get as old as I am, you start to realize that you've told most of the good stuff you know… — Richard P. Feynman Copy Share Image
Some people say, "How can you live without knowing?" I do not know what they mean. I always live without knowing. That… — Richard P. Feynman Copy Share Image
Everything we know is only some kind of approximation, because we know that we do not know all the laws yet. Therefore,… — Richard P. Feynman Copy Share Image
It's because somebody knows something about it that we can't talk about physics. It's the things that nobody knows anything about we… — Richard P. Feynman Copy Share Image
The present situation in physics is as if we know chess, but we don't know one or two rules. — Richard P. Feynman Copy Share Image
I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers,… — Richard P. Feynman Copy Share Image
When a scientist doesn't know the answer to a problem, he is ignorant. When he has a hunch as to what the… — Richard P. Feynman Copy Share Image
You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely… — Richard P. Feynman Copy Share Image
We have this terrible struggle to try to explain things to people who have no reason to want to know. — Richard P. Feynman Copy Share Image
So far as we know, all the fundamental laws of physics, like Newton's equations, are reversible. — Richard P. Feynman Copy Share Image
One of the ways of stopping science would be only to do experiments in the region where you know the law. But… — Richard P. Feynman Copy Share Image
If you know that you are not sure, you have a chance to improve the situation. I want to demand this freedom… — Richard P. Feynman Copy Share Image
You know how it always is, every new idea, it takes a generation or two until it becomes obvious that there's no… — Richard P. Feynman Copy Share Image
I am going to tell you what nature behaves like. If you will simply admit that maybe she does behave like this,… — Richard P. Feynman Copy Share Image
Know your place in the world and evaluate yourself fairly, not in terms of the naive ideals of your own youth, nor… — Richard P. Feynman Copy Share Image
All things are made of atoms - little particles that move around in perpetual motion, attracting each other when they are a… — Richard P. Feynman Copy Share Image
“Philosophers have said before that one of the fundamental requisites of science is that whenever you set up the same conditions, the same thing… — Richard P. Feynman Copy Share Image
My rule is, when you are unhappy, think about it. But when you're happy, don't. Why spoil it? You're probably happy for some ridiculous… — Richard P. Feynman Copy Share Image
Trying to understand the way nature works involves a most terrible test of human reasoning ability. It involves subtle trickery, beautiful tightropes of logic… — Richard P. Feynman Copy Share Image
Mathematics is a language plus reasoning; it is like a language plus logic. Mathematics is a tool for reasoning. — Richard P. Feynman Copy Share Image
It is necessary for the very existence of science that minds exist which do not allow that nature must satisfy some preconceived conditions. — Richard P. Feynman Copy Share Image
“There was a Princess Somebody of Denmark sitting at a table with a number of people around her, and I saw an empty chair… — Richard P. Feynman Copy Share Image
All the time you're saying to yourself, 'I could do that, but I won't,'--which is just another way of saying that you can't. — Richard P. Feynman Copy Share Image
“There's a big difference between knowing the name of something and knowing something.” — Richard P. Feynman Copy Share Image
The fact that you are not sure means that it is possible that there is another way someday. — Richard P. Feynman Copy Share Image
One cannot understand... the universality of laws of nature, the relationship of things, without an understanding of mathematics. There is no other way to… — Richard P. Feynman Copy Share Image
