Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.
Scientists are explorers. Philosophers are tourists.
To develop working ideas efficiently, I try to fail as fast as I can.
Progress in science comes when experiments contradict theory.
I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers, and possible beliefs, and different degrees of uncertainty about different things, but I am not absolutely sure of anything. There are many things I don't know anything about, such as whether it means anything to ask "Why are we here?" I might think about it a little bit, and if I can't figure it out then I go on to something else. But I don't have to know an answer. I don't feel frightened by not knowing things, by being lost in the mysterious universe without having any purpose - which is the way it really is, as far as I can tell.
I learned very early the difference between knowing the name of something and knowing something.
The truth always turns out to be simpler than you thought.
When a scientist doesn't know the answer to a problem, he is ignorant. When he has a hunch as to what the result is, he is uncertain. And when he is pretty darn sure of what the result is going to be, he is still in some doubt. We have found it of paramount importance that in order to progress we must recognize our ignorance and leave room for doubt. Scientific knowledge is a body of statements of varying degrees of certainty - some most unsure, some nearly sure, but none absolutely certain.
The highest forms of understanding we can achieve are laughter and human compassion.
No government has the right to decide on the truth of scientific principles, nor to prescribe in any way the character of the questions investigated. Neither may a government determine the aesthetic value of artistic creations, nor limit the forms of literacy or artistic expression. Nor should it pronounce on the validity of economic, historic, religious, or philosophical doctrines. Instead it has a duty to its citizens to maintain the freedom, to let those citizens contribute to the further adventure and the development of the human race.
I wonder why. I wonder why. I wonder why I wonder.
Teach principles not formulas.
Outside of their particular area of expertise scientists are just as dumb as the next person.
What is not surrounded by uncertainty cannot be the truth.
The only way to deep happiness is to do something you love to the best of your ability
Physics is like sex: sure, it may give some practical results, but that's not why we do it.
Science is the organized skepticism in the reliability of expert opinion
The thing that doesn't fit is the thing that is most interesting.
It does not matter who you are, or how smart you are, or what title you have, or how many of you there are, and certainly not how many papers your side has published, if your prediction is wrong then your hypothesis is wrong. Period.
We have this terrible struggle to try to explain things to people who have no reason to want to know.
The "paradox" is only a conflict between reality and your feeling of what reality "ought to be."
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.
The test of all knowledge is experiment.
There is no learning without having to pose a question. And a question requires doubt.
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.
