We find that the statements of science are not of what is true and what is not true, but statements of what is known with different degrees of certainty: "It is very much more likely that so and so is true than that it is not true".
If you know that you are not sure, you have a chance to improve the situation. I want to demand this freedom for future generations.
Mathematics is not just a language. Mathematics is a language plus reasoning.
I do believe that there is a conflict between science and religion ... the spirit or attitude toward the facts is different in religion from what it is in science. The uncertainty that is necessary in order to appreciate nature is not easily correlated with the feeling of certainty in faith.
Science is a way of trying not to fool yourself.
All the time you're saying to yourself, 'I could do that, but I won't,'--which is just another way of saying that you can't.
It is scientific only to say what is more likely and what less likely, and not to be proving all the time the possible and impossible.

It does not make any difference how beautiful your guess is. It does not make any difference how smart you are, who made the guess, or what his name is if it disagrees with experiment it is wrong. That is all there is to it.
There are 10^11 stars in the galaxy. That used to be a huge number. But it's only a hundred billion. It's less than the national deficit! We used to call them astronomical numbers. Now we should call them economical numbers.
Of course, you only live one life, and you make all your mistakes, and learn what not to do, and that's the end of you.
We cannot define anything precisely. If we attempt to, we get into the paralysis of thought that comes to philosophers, who sit opposite each other, one saying to the other, "You don't know what you are talking about!" The second one says, "What do you mean by know? What do you mean by talking? What do you mean by you?"
The theoretical broadening which comes from having many humanities subjects on the campus is offset by the general dopiness of the people who study these things.
Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.

But logic is not all, one needs one's heart to follow an idea.
For those who want some proof that physicists are human, the proof is in the idiocy of all the different units which they use for measuring energy.
I have to disregard everybody else, and then I can do my own work.
It is important to realize that in physics today, we have no knowledge of what energy is
