Richard Feynman Quotes
-
There’s so much distance between the fundamental rules and the final phenomenon, that it’s almost unbelievable that the final variety of phenomenon can come from such a steady operation of such simple rules.
-
Physics is like sex: sure, it may give some practical results, but that's not why we do it.
-
The test of all knowledge is experiment.
-
I don't think that the laws can be considered to be like God because they have been figured out.
-
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.
-
We scientists are clever — too clever — are you not satisfied? Is four square miles in one bomb not enough? Men are still thinking. Just tell us how big you want it!
-
Progress in science comes when experiments contradict theory.
-
The exception tests the rule.
-
Scientific knowledge is a body of statements of varying degrees of certainty -- some most unsure, some nearly sure, none absolutely certain.
-
Science is what we do to keep us from lying to ourselves
-
Our freedom to doubt was born out of a struggle against authority in the early days of science. It was a very deep and strong struggle: permit us to question - to doubt - to not be sure. I think that it is important that we do not forget this struggle and thus perhaps lose what we have gained.
-
Therefore psychologically we must keep all the theories in our heads, and every theoretical physicist who is any good knows six or seven different theoretical representations for exactly the same physics.
-
I couldn't claim that I was smarter than sixty-five other guys--but the average of sixty-five other guys, certainly!
-
Science is uncertain.
-
The game I play is a very interesting one. It's imagination, in a tight straightjacket.
-
Science is of value because it can produce something.
-
Just as a poet often has license from the rules of grammar and pronunciation, we should like to ask for 'physicists' license from the rules of mathematics in order to express what we wish to say in as simple a manner as possible.
-
People who wish to analyze nature without using mathematics must settle for a reduced understanding.
-
So, ultimately, in order to understand nature it may be necessary to have a deeper understanding of mathematical relationships. But the real reason is that the subject is enjoyable, and although we humans cut nature up in different ways, and we have different courses in different departments, such compartmentaliz ation is really artificial, and we should take our intellectual pleasures where we find them.
-
This is not very important what I'm doing. I'm just proving something.
-
I think a power to do something is of value. Whether the result is a good thing or a bad thing depends on how it is used, but the power is a value.
-
As you know, a theory in physics is not useful unless it is able to predict underlined effects which we would otherwise expect.
-
The basis of action on love, the brotherhood of all men, the value of the individual... the humility of the spirit.
-
A great deal more is known than has been proved.
