Don't worry about anything. Go out and have a good time.
Richard Feynman -
Every instrument that has been designed to be sensitive enough to detect weak light has always ended up discovering that the same thing: light is made of particles.

Nature has a great simplicity and therefore a great beauty.
Richard Feynman -
Since then I never pay attention to anything by "experts". I calculate everything myself.
Richard Feynman -
You have no responsibility to live up to what other people think you ought to accomplish. I have no responsibility to be like they expect me to be. It's their mistake, not my failing.
Richard Feynman -
We never are definitely right, we can only be sure we are wrong.
Richard Feynman -
Nature does not care what we call it, she just keeps on doing it.
Richard Feynman -
The work I have done has, already, been adequately rewarded and recognized. Imagination reaches out repeatedly trying to achieve some higher level of understanding, until suddenly I find myself momentarily alone before one new corner of nature's pattern of beauty and true majesty revealed. That was my reward.

You should not fool the laymen when you're talking as a scientist... . I'm talking about a specific, extra type of integrity that is not lying, but bending over backwards to show how you're maybe wrong, an integrity that you ought to have when acting as a scientist. And this is our responsibility as scientists, certainly to other scientists, and I think to laymen.
Richard Feynman -
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.
Richard Feynman -
It appears that there are enormous differences of opinion as to the probability of a failure with loss of vehicle and of human life. The estimates range from roughly 1 in 100 to 1 in 100,000. The higher figures come from the working engineers, and the very low figures from management.
Richard Feynman -
It is necessary for the very existence of science that minds exist which do not allow that nature must satisfy some preconceived conditions.
Richard Feynman -
There's plenty of room at the bottom.
Richard Feynman -
Science is a process for learning about nature in which competing ideas about how the world works are measured against observations.
Richard Feynman

Do not read so much, look about you and think of what you see there.
Richard Feynman -
I think a power to do something is of value. Whether the result is a good thing or a bad thing depends on how it is used, but the power is a value.
Richard Feynman -
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.
Richard Feynman -
You can know the name of a bird in all the languages of the world, but when you're finished, you'll know absolutely nothing whatever about the bird... So let's look at the bird and see what it's doing -- that's what counts.
Richard Feynman -
You know how it always is, every new idea, it takes a generation or two until it becomes obvious that there's no real problem. It has not yet become obvious to me that there's no real problem. I cannot define the real problem, therefore I suspect there's no real problem, but I'm not sure there's no real problem.
Richard Feynman -
The game I play is a very interesting one. It's imagination in a straightjacket, which is this: that it has to agree with the known laws of physics. ... It requires imagination to think of what's possible, and then it requires an analysis back, checking to see whether it fits, whether its allowed, according to what's known, okay?
Richard Feynman
-
I'm going to play with physics, whenever I want to, without worrying about any importance whatsoever.
Richard Feynman -
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.
Richard Feynman -
What I am going to tell you about is what we teach our physics students in the third or fourth year of graduate school... It is my task to convince you not to turn away because you don't understand it. You see my physics students don't understand it... That is because I don't understand it. Nobody does.
Richard Feynman -
Know your place in the world and evaluate yourself fairly, not in terms of the naïve ideals of your own youth, nor in terms of what you erroneously imagine your teacher's ideals are.
