A Quote by Richard P. Feynman

We're always, by the way, in fundamental physics, always trying to investigate those things in which we don't understand the conclusions. After we've checked them enough, we're okay.
We leap to conclusions and remember those conclusions as fact. We react on our own prejudices but don't always recognize them as such.
The first thing to realize about physics ... is its extraordinary indirectness.... For physics is not about the real world, it is about "abstractions" from the real world, and this is what makes it so scientific.... Theoretical physics runs merrily along with these unreal abstractions, but its conclusions are checked, at every possible point, by experiments.
The mathematical is that evident aspect of things within which we are always already moving and according to which we experience them as things at all, and as such things. The mathematical is this fundamental position we take toward things by which we take up things as already given to us, and as they must and should be given. Therefore, the mathematical is the fundamental presupposition of the knowledge of things.
While there is such a thing as correctness in ethics, in interpretation, in mathematics, the way to understand that is not by trying to model it on the ways in which we get things right in physics.
We get the exciting result that the total energy of the universe is zero. Why this should be so is one of the great mysteries - and therefore one of the important questions of physics. After all, what would be the use of studying physics if the mysteries were not the most important things to investigate?
The problem is that modern fundamental physics is so far from you and me. The mathematics has become so much more complicated that you need at least 10 years to understand it. Fundamental physics has advanced so far from the understanding of most people that there is really a big disconnect.
I think I always wanted to go into physics. What always fascinated me about science was the desire to understand what underlies it all, and I think physics is basically the study of that.
I guess I was just always one of those guys who asked those fundamental questions: 'Who am I? What's this for? Why? What does this mean? Is this real?' All these pretty basic questions. I like making movies about people who are self-conscious in that way, and are trying to feel their way through the world.
It is always good to know which ideas cannot be checked directly, but it is not necessary to remove them all. It is not true that we can pursue science completely by using only those concepts which are directly subject to experiment.
For me, science is already fantastical enough. Unlocking the secrets of nature with fundamental physics or cosmology or astrobiology leads you into a wonderland compared with which beliefs in things like alien abductions pale into insignificance.
I'm always going to be a student. I'm always learning. I'm always trying to grow. I'm always trying to understand. I never want to feel like I've arrived.
When I first came to New York, I knew some painters older than myself. I was kind of the kid who was allowed to hang out with them. That is more the way people talked in those days, it was perfectly normal to question a work's fundamental premises and its fundamental visual manifestations. It was perfectly okay to say, "Oh, that should have been red" or something like that. In a funny way, the way artists talk about art is to de-privilege it.
He [Hitler] seemed very depressed and upset about the Stalingrad disaster. He said that one is always liable to look on the black side of things after a defeat, a tendency which can lead one into dangerous and false conclusions.
This is the problem with the way you educate your children. You don't want your young ones drawing their own conclusions. You want them to come to the same conclusions that you came to. Thus you doom them to repeat the mistakes to which your own conclusions led you.
We could tell them [alien civilization] things that we have discovered in the realm of mathematical physics, but there is stuff that I would like to know. There are some famous problems like how to bring gravitation and quantum physics together, the long-sought-after theory of quantum gravity. But it may be hard to understand the answer that comes back.
When I began my career as a cosmologist some twenty years ago, I was a convinced atheist. I never in my wildest dreams imagined that one day I would be writing a book purporting to show that the central claims of Judeo-Christian theology are in fact true, that these claims are straightforward deductions of the laws of physics as we now understand them. I have been forced into these conclusions by the inexorable logic of my own special branch of physics.
