Quotes from Richard P. Feynman

The only way to deep happiness is to do something you love to the best of your ability

Fall in love with some activity, and do it! Nobody ever figures out what life is all about, and it doesn't matter.

It always seems odd to me that the fundamental laws of physics, when discovered, can appear in so many different forms that are not apparently identical at first, but, with a little mathematical fiddling, you can show the relationship.

If I could explain it to the average person, it wouldn't have been worth the Nobel Prize.

I don't understand what it's all about or what's worth what, but if the people in the Swedish Academy decide that x, y or z wins the Nobel Prize, then so be it.

There are thousands of years in the past, and there is an unknown amount of time in the future. There are all kinds of opportunities, and there are all kinds of dangers.

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.

The philosophical question before us is, when we make an observation of our track in the past, does the result of our observation become real in the same sense that the final state would be defined if an outside observer were to make the observation?

The truth always turns out to be simpler than you thought.

I got a fancy reputation. During high school, every puzzle that was known to man must have come to me. Every damn, crazy conundrum that people had invented, I knew.

I got a signed document from Bullock's saying that they had such-and-such drawings on consignment. Of course, nobody bought any of them, but otherwise, I was a big success: I had my drawings on sale at Bullock's!

I was terrible in English. I couldn't stand the subject. It seemed to me ridiculous to worry about whether you spelled something wrong or not, because English spelling is just a human convention - it has nothing to do with anything real, anything from nature.

We are at the very beginning of time for the human race. It is not unreasonable that we grapple with problems. But there are tens of thousands of years in the future. Our responsibility is to do what we can, learn what we can, improve the solutions, and pass them on.

What is not surrounded by uncertainty cannot be the truth.

As revealed by physics, the truth is so remarkable, so amazing!

In any decision for action, when you have to make up your mind what to do, there is always a 'should' involved, and this cannot be worked out from, 'If I do this, what will happen?' alone.

When I was a young man, Dirac was my hero. He made a breakthrough, a new method of doing physics. He had the courage to simply guess at the form of an equation, the equation we now call the Dirac equation, and to try to interpret it afterwards.

We have this terrible struggle to try to explain things to people who have no reason to want to know.

I love to think. I once considered taking drugs as an attempt to better understand an altered state of mind; however, I decided not to. I didn't want to chance ruining the machine.

One does not, by knowing all the physical laws as we know them today, immediately obtain an understanding of anything much. I love only nature, and I hate mathematicians.

I think equation guessing might be the best method to proceed to obtain the laws for the part of physics which is presently unknown. Yet, when I was much younger, I tried this equation guessing, and I have seen many students try this, but it is very easy to go off in wildly incorrect and impossible directions.

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.

Nature isn't classical, dammit, and if you want to make a simulation of nature, you'd better make it quantum mechanical, and by golly it's a wonderful problem, because it doesn't look so easy.

Today we say that the law of relativity is supposed to be true at all energies, but someday somebody may come along and say how stupid we were.
