If you keep proving stuff that others have done, getting confidence, increasing the complexities of your solutions - for the fun of… — Richard P. Feynman Copy Share Image
The most important thing I found out from my father is that if you asked any question and pursued it deeply enough,… — Richard P. Feynman Copy Share Image
Only realistic flight schedules should be proposed, schedules that have a reasonable chance of being met. If in this way the government… — Richard P. Feynman Copy Share Image
We've learned from experience that the truth will come out. Other experimenters will repeat your experiment and find out whether you were… — 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
Although it is uncertain, it is necessary to make science useful. Science is only useful if it tells you about some experiment… — Richard P. Feynman Copy Share Image
If science is to progress, what we need is the ability to experiment, honesty in reporting results—the results must be reported without… — Richard P. Feynman Copy Share Image
That is the logical tight-rope on which we have to walk if we wish to interpret nature. — 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
To guess what to keep and what to throw away takes considerable skill. Actually it is probably merely a matter of luck,… — Richard P. Feynman Copy Share Image
To do any important work in physics a very good mathematical ability and aptitude are required. Some work in applications can be… — Richard P. Feynman Copy Share Image
If you have any talent, or any occupation that delights you, do it, and do it to the hilt. Don't ask why,… — Richard P. Feynman Copy Share Image
It does not matter who you are, or how smart you are, or what title you have, or how many of you… — Richard P. Feynman Copy Share Image
If you think you understand quantum mechanics, you don't understand quantum mechanics. — 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
The idea that no one really knew how to run a government led to the idea that we should arrange a system… — Richard P. Feynman Copy Share Image
The only way to have real success in science, the field I'm familiar with, is to describe the evidence very carefully without… — Richard P. Feynman Copy Share Image
If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives. — Richard P. Feynman Copy Share Image
When a photon comes down, it interacts with electrons throughout the glass, not just on the surface. The photon and electrons do… — Richard P. Feynman Copy Share Image
During the Middle Ages there were all kinds of crazy ideas, such as that a piece of rhinoceros horn would increase potency.… — Richard P. Feynman Copy Share Image
What would happen if we could arrange the atoms one by one the way we want them? — Richard P. Feynman Copy Share Image
'Conservation' (the conservation law) means this ... that there is a number, which you can calculate, at one moment-and as nature undergoes… — Richard P. Feynman Copy Share Image
If you don't like it, go somewhere else, to another universe where the rules are simpler. — 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
