Richard Feynman Quotes
-
In its efforts to learn as much as possible about nature, modern physics has found that certain things can never be "known" with certainty. Much of our knowledge must always remain uncertain. The most we can know is in terms of probabilities.
-
I believe that a scientist looking at nonscientific problems is just as dumb as the next guy.
-
Beyond poverty, beyond the point that the material needs are reasonably satisfied, only from within is peace.
-
It is simple, therefore it is beautiful
-
It is necessary for the very existence of science that minds exist which do not allow that nature must satisfy some preconceived conditions.
-
The beauty that is there is also available for me, too. But I see a deeper beauty that isn't so readily available to others.... I don't see how studying a flower ever detracts from its beauty. It only adds
-
There is no harm in doubt and skepticism, for it is through these that new discoveries are made.
-
Winning a Nobel Prize is no big deal, but winning it with an IQ of 124 is really something.
-
The present situation in physics is as if we know chess, but we don't know one or two rules.
-
The work I have done has, already, been adequately rewarded and recognized. Imagination reaches out repeatedly trying to achieve some higher level of understanding, until suddenly I find myself momentarily alone before one new corner of nature's pattern of beauty and true majesty revealed. That was my reward.
-
All we know so far is what doesn't work.
-
The electron is a theory. But the theory is so good we can almost consider them real.
-
The chance is high that the truth lies in the fashionable direction. But, on the off-chance that it is in another direction - a direction obvious from an unfashionable view of field theory - who will find it? Only someone who has sacrificed himself by teaching himself quantum electrodynamics from a peculiar and unusual point of view; one that he may have to invent for himself.
-
I wonder why. I wonder why. I wonder why I wonder.
-
Science is like sex: sometimes something useful comes out, but that is not the reason we are doing it
-
The unanswerable mysteries... the attitude that all is uncertain... to summarize it - the humility of the intellect.
-
I don't know what's the matter with people: they don't learn by understanding, they learn by some other way — by rote or something. Their knowledge is so fragile!
-
In fact the total amount that a physicist knows is very little. He has only to remember the rules to get him from one place to another and he is all right.
-
Today's brains are yesterday's mashed potatoes.
-
I can live with doubt and uncertainty and not knowing. I think it is much more interesting to live not knowing than to have answers that might be wrong. If we will only allow that, as we progress, we remain unsure, we will leave opportunities for alternatives.

-
Know your place in the world and evaluate yourself fairly, not in terms of the naïve ideals of your own youth, nor in terms of what you erroneously imagine your teacher's ideals are.
-
One cannot understand... the universality of laws of nature, the relationship of things, without an understanding of mathematics. There is no other way to do it.
-
I'm trying to find out NOT how Nature could be, but how Nature IS.
