If you thought that science was certain - well, that is just an error on your part. — Richard P. Feynman Copy Share Image
Observation, reason, and experiment make up what we call the scientific method. — Richard P. Feynman Copy Share Image
It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's… — Richard P. Feynman Copy Share Image
Science is a process for learning about nature in which competing ideas about how the world works are measured against observations. — Richard P. Feynman Copy Share Image
I learned very early the difference between knowing the name of something and knowing something. — Richard P. Feynman Copy Share Image
But the real glory of science is that we can find a way of thinking such that the law is evident. — Richard P. Feynman Copy Share Image
“psychoanalysis is not a science: it is at best a medical process, and perhaps even more like witch-doctoring.” — Richard P. Feynman Copy Share Image
“I think we should teach them [the people] wonders and that the purpose of knowledge is to appreciate wonders even more.” — Richard P. Feynman Copy Share Image
I've always been very one-sided about science, and when I was younger, I concentrated almost all my effort on it. — Richard P. Feynman Copy Share Image
Our imagination is stretched to the utmost, not, as in fiction, to imagine things which are not really there, but just to… — 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
“Once you start doubting, just like you’re supposed to doubt, you ask me if the science is true. You say no, we… — Richard P. Feynman Copy Share Image
It is odd, but on the infrequent occasions when I have been called upon in a formal place to play the bongo… — Richard P. Feynman Copy Share Image
Science is a way to teach how something gets to be known, what is not known, to what extent things are known… — 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
We find that the statements of science are not of what is true and what is not true, but statements of what… — Richard P. Feynman Copy Share Image
[When a young person loses faith in his religion because he begins to study science and its methodology] it isn't that [through… — 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
“I believe, therefore, that although it is not the case today, that there may some day come a time, I should hope,… — Richard P. Feynman Copy Share Image
Another of the qualities of science is that it teaches the value of rational thought, as well as the importance of freedom… — Richard P. Feynman Copy Share Image
“In general, we look for a new law by the following process: First we guess it; then we compute the consequences of… — Richard P. Feynman Copy Share Image
The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge… — 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
We have a habit in writing articles published in scientific journals to make the work as finished as possible, to cover up… — Richard P. Feynman Copy Share Image
In fact, the science of thermodynamics began with an analysis, by the great engineer Sadi Carnot, of the problem of how to… — Richard P. Feynman Copy Share Image
What is the fundamental hypothesis of science, the fundamental philosophy? We stated it in the first chapter: the sole test of the… — 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
