Richard Feynman Quotes
-
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.
-
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.
-
A great deal more is known than has been proved.
-
Nature's imagination far surpasses our own.
-
If I could explain it to the average person, I wouldn't have been worth the Nobel Prize.
-
Outside of their particular area of expertise scientists are just as dumb as the next person.
-
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.
-
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.
-
As you know, a theory in physics is not useful unless it is able to predict underlined effects which we would otherwise expect.
-
The other thing that gives a scientific man the creeps in the world today are the methods of choosing leaders - in every nation. Today, for example, in the United States, the two political parties have decided to employ public relations men, that is, advertising men, who are trained in the necessary methods of telling the truth or lying in order to develop a product.
-
The thing that doesn't fit is the thing that is most interesting.
-
To decide upon the answer is not scientific. In order to make progress, one must leave the door to the unknown ajar ajar only.
-
Physics is like sex: sure, it may give some practical results, but that's not why we do it.
-
When the problem quantum chromodynamics is finally solved, it will all be by imagination. Then there will be some big thing about the great way it was done. But it's simple -it will all be by imagination, and persistence.
-
Few people realize the number of things that are possible.
-
I'm going to play with physics, whenever I want to, without worrying about any importance whatsoever.
-
Science is of value because it can produce something.
-
The test of all knowledge is experiment.
-
What Do You Care What Other People Think?
-
I have argued flying saucers with lots of people. I was interested in possible. They do not appreciate that the problem is not to demonstrate whether it's possible or not but whether it's going on or not.
-
What did you ASK at school today?
-
People often think I'm a faker, but I'm usually honest, in a certain way--in such a way that often nobody believes me!
-
The worthwhile problems are the ones you can really solve or help solve, the ones you can really contribute something to... No problem is too small or too trivial if we can really do something about it.
-
It's because somebody knows something about it that we can't talk about physics. It's the things that nobody knows anything about we can discuss.
