Teach principles not formulas.
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.
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.
Science is the organized skepticism in the reliability of expert opinion
The truth always turns out to be simpler than you thought.
I learned very early the difference between knowing the name of something and knowing something.
We absolutely must leave room for doubt or there is no progress and no learning. There is no learning without having to pose a question. And a question requires doubt. People search for certainty. But there is no certainty.
We have this terrible struggle to try to explain things to people who have no reason to want to know.
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.
Scientists are explorers. Philosophers are tourists.
The only way to deep happiness is to do something you love to the best of your ability
Scientific knowledge is a body of statements of varying degrees of certainty -- some most unsure, some nearly sure, none absolutely certain.
Have no respect whatsoever for authority; forget who said it and instead look what he starts with, where he ends up, and ask yourself, "Is it reasonable?"
The highest forms of understanding we can achieve are laughter and human compassion.
What is not surrounded by uncertainty cannot be the truth.
The thing that doesn't fit is the thing that is most interesting.
What I cannot create, I do not understand.
Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.
Physics is like sex: sure, it may give some practical results, but that's not why we do it.
I wonder why. I wonder why. I wonder why I wonder.
Progress in science comes when experiments contradict theory.
Outside of their particular area of expertise scientists are just as dumb as the next person.
In physics the truth is rarely perfectly clear, and that is certainly universally the case in human affairs. Hence, what is not surrounded by uncertainty cannot be the truth.
There is no learning without having to pose a question. And a question requires doubt.
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.
