Richard Feynman Quotes
-
But logic is not all, one needs one's heart to follow an idea.
-
There are theoretical physicists who imagine, deduce, and guess at new laws, but do not experiment; and then there are experimental physicists who experiment, imagine, deduce, and guess.
-
Maybe that is why young people make success. They don't know enough.
-
All theoretical chemistry is really physics; and all theoretical chemists know it.
-
It is necessary for the very existence of science that minds exist which do not allow that nature must satisfy some preconceived conditions.
-
Since then I never pay attention to anything by "experts". I calculate everything myself.
-
Another of the qualities of science is that it teaches the value of rational thought, as well as the importance of freedom of thought; the positive results that come from doubting that all the lessons are true... Learn from science that you must doubt the experts. As a matter of fact, I can also define science another way: Science is the belief in the ignorance of experts.
-
All we know so far is what doesn't work.
-
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!
-
Observation, reason, and experiment make up what we call the scientific method.
-
One does not, by knowing all the physical laws as we know them today, immediately obtain an understanding of anything much. I love only nature, and I hate mathematicians.
-
I think I can safely say that nobody understands Quantum Mechanics.
-
Work as hard and as much as you want to on the things you like to do the best.
-
Victory usually goes to those green enough to underestimate the monumental hurdles they are facing.
-
Science is a way of trying not to fool yourself.
-
Outside of their particular area of expertise scientists are just as dumb as the next person.
-
The only way to deep happiness is to do something you love to the best of your ability
-
The thing that doesn't fit is the thing that is most interesting.
-
A poet once said, "The whole universe is in a glass of wine." We will probably never know in what sense he meant that, for poets do not write to be understood. But it is true that if we look at a glass of wine closely enough we see the entire universe.
-
In any organization there ought to be the possibility of discussion... fence sitting is an art, and it's difficult, and it's important to do, rather than to go headlong in one direction or the other. It's just better to have action, isn't it than to sit on the fence? Not if you're not sure which way to go, it isn't.
-
To test whether you have learned an idea or a definition, rephrase what you just learned without using the new word.
-
What is not surrounded by uncertainty cannot be the truth.
-
I'm going to play with physics, whenever I want to, without worrying about any importance whatsoever.
-
What is the fundamental hypothesis of science, the fundamental philosophy? We stated it in the first chapter: the sole test of the validity of any idea is experiment. ... If we are told that the same experiment will always produce the same result, that is all very well, but if when we try it, it does not, then it does not. We just have to take what we see, and then formulate all the rest of our ideas in terms of our actual experience.
