Richard Feynman Quotes
-
The truth always turns out to be simpler than you thought.
-
You see, one thing is, I can live with doubt and uncertainty and not knowing. I have approximate answers and possible beliefs and different degrees of certainty about different things... It doesn't frighten me.
-
To develop working ideas efficiently, I try to fail as fast as I can.
-
It is not unscientific to make a guess, although many people who are not in science think it is.
-
The real question of government versus private enterprise is argued on too philosophical and abstract a basis. Theoretically, planning may be good. But nobody has ever figured out the cause of government stupidity—and until they do (and find the cure), all ideal plans will fall into quicksand.
-
No man is rich who is unsatisfied, but who wants nothing possess his heart's desire.
-
Words can be meaningless. If they are used in such a way that no sharp conclusions can be drawn.
-
The game I play is a very interesting one. It's imagination, in a tight straightjacket.
-
Everything we know is only some kind of approximation, because we know that we do not know all the laws yet. Therefore, things must be learned only to be unlearned again or, more likely, to be corrected.
-
When you get as old as I am, you start to realize that you've told most of the good stuff you know to other people anyway.
-
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 are lucky to live in an age in which we are still making discoveries.
-
Why make yourself miserable saying things like, "Why do we have such bad luck? What has God done to us? What have we done to deserve this?" - all of which, if you understand reality and take it completely into your heart, are irrelevant and unsolvable. They are just things that nobody can know. Your situation is just an accident of life.
-
Nobody ever figures out what life is all about, and it doesn't matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough.
-
I have to keep going to find out ultimately what is the matter with it in the end.
-
In fact, the science of thermodynamics began with an analysis, by the great engineer Sadi Carnot, of the problem of how to build the best and most efficient engine, and this constitutes one of the few famous cases in which engineering has contributed to fundamental physical theory. Another example that comes to mind is the more recent analysis of information theory by Claude Shannon. These two analyses, incidentally, turn out to be closely related.
-
It is important to realize that in physics today, we have no knowledge of what energy is
-
I would rather have questions that can't be answered than answers that can't be questioned.
-
Poets say science takes away from the beauty of the stars - mere globs of gas atoms. I, too, can see the stars on a desert night, and feel them. But do I see less or more?
-
There was a time when the newspapers said that only twelve men understood the theory of relativity. I do not believe there ever was such a time ... On the other hand, I think I can safely say that nobody understands quantum mechanics.
-
But the real glory of science is that we can find a way of thinking such that the law is evident.
-
I think it's much more interesting to live not knowing than to have answers which might be wrong.
-
Thank you very Much, I enjoyed myself
-
The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific "truth." But what is the source of knowledge? Where do the laws that are to be tested come from? Experiment, itself, helps to produce these laws, in the sense that it gives us hints. But also needed is imagination to create from these hints the great generalizations--to guess at the wonderful, simple, but very strange patterns beneath them all, and then to experiment to check again whether we have made the right guess.
