Richard Feynman Quotes

Looking back at the worst times, it always seems that they were times in which there were people who believed with absolute faith and absolute dogmatism in something. And they were so serious in this matter that they insisted that the rest of the world agree with them. And then they would do things that were directly inconsistent with their own beliefs in order to maintain that what they said was true.

I took this stuff I got out of your [O-ring] seal and I put it in ice water, and I discovered that when you put some pressure on it for a while and then undo it it doesn't stretch back. It stays the same dimension. In other words, for a few seconds at least, and more seconds than that, there is no resilience in this particular material when it is at a temperature of 32 degrees. I believe that has some significance for our problem.

I would rather have questions that can’t be answered than answers that can’t be questioned.

Learn what the rest of the world is like. The variety is worthwhile.

Anyway, Smith told me to sign some papers for the three ideas I was giving to the government to patent. Now, it’s some dopey legal thing, but when you give the patent to the government, the document you sign is not a legal document unless there’s some exchange, so the paper I signed said, “For the sum of one dollar, I, Richard P. Feynman, give this idea to the government…” I sign the paper. “Where’s my dollar?” “That’s just a formality,” he says. “We haven’t got any funds set up to give a dollar.” “You’ve got it all set up that I’m signing for the dollar,” I say. “I want my dollar!” “This is silly,” Smith protests. “No, it’s not,” I say. “It’s a legal document. You made me sign it, and I’m an honest man. If I sign something that says I got a dollar, I’ve gotta get a dollar. There’s no fooling around about it.” “All right, all right!” he says, exasperated. “I’ll give you a dollar, from my pocket!” “OK.” I take the dollar, and I realize what I’m going to do. I go down to the grocery store, and I buy a dollar’s worth — which was pretty good, then — of cookies and goodies, those chocolate goodies with marshmallow inside, a whole lot of stuff. I come back to the theoretical laboratory, and I give them out: “I got a prize, everybody! Have a cookie! I got a prize! A dollar for my patent! I got a dollar for my patent!” Everybody who had one of those patents — a lot of people had been sending them in — everybody comes down to Captain Smith: they want their dollar!

You are under no obligation to remain the same person you were a year ago, a month ago, or even a day ago. You are here to create yourself, continuously.

The lay reader only wanted to have the illusion of understanding and to catch a few buzzwords to throw around at cocktail parties.

I mumbled something about how it was easy to calculate e to any power using that series (you just substitute the power for x). “Oh yeah?” they said, “Well, then, what’s e to the 3.3?” said some joker — I think it was Tukey. I say, “That’s easy. It’s 27.11.” Tukey knows it isn’t so easy to compute all that in your head. “Hey! How’d you do that?” Another guy says, “You know Feynman, he’s just faking it. It’s not really right.” They go to get a table, and while they’re doing that, I put on a few more figures: “27.1126,” I say. They find it in the table. “It’s right! But how’d you do it!” “I just summed the series.” “Nobody can sum the series that fast. You must just happen to know that one. How about e to the 3?” “Look,” I say. “It’s hard work! Only one a day!” “Hah! It’s a fake!” they say, happily. “All right,” I say, “It’s 20.085.

A poet once said, "The whole universe is in a glass of wine." We will probably never know in what sense he meant that, for poets do not write to be understood. But it is true that if we look at a glass of wine closely enough we see the entire universe. There are the things of physics: the twisting liquid which evaporates depending on the wind and weather, the reflections in the glass, and our imagination adds the atoms. The glass is a distillation of the Earth's rocks, and in its composition we see the secrets of the universe's age, and the evolution of stars. What strange arrays of chemicals are in the wine? How did they come to be? There are the ferments, the enzymes, the substrates, and the products. There in wine is found the great generalization: all life is fermentation. Nobody can discover the chemistry of wine without discovering, as did Louis Pasteur, the cause of much disease. How vivid is the claret, pressing its existence into the consciousness that watches it! If our small minds, for some convenience, divide this glass of wine, this universe, into parts — physics, biology, geology, astronomy, psychology, and so on — remember that nature does not know it! So let us put it all back together, not forgetting ultimately what it is for. Let it give us one more final pleasure: drink it and forget it all!

D’Arline,

I adore you, sweetheart.

I know how much you like to hear that — but I don't only write it because you like it — I write it because it makes me warm all over inside to write it to you.

It is such a terribly long time since I last wrote to you — almost two years but I know you'll excuse me because you understand how I am, stubborn and realistic; and I thought there was no sense to writing.

But now I know my darling wife that it is right to do what I have delayed in doing, and that I have done so much in the past. I want to tell you I love you. I want to love you. I always will love you.

I find it hard to understand in my mind what it means to love you after you are dead — but I still want to comfort and take care of you — and I want you to love me and care for me. I want to have problems to discuss with you — I want to do little projects with you. I never thought until just now that we can do that. What should we do. We started to learn to make clothes together — or learn Chinese — or getting a movie projector. Can't I do something now? No. I am alone without you and you were the "idea-woman" and general instigator of all our wild adventures.

When you were sick you worried because you could not give me something that you wanted to and thought I needed. You needn’t have worried. Just as I told you then there was no real need because I loved you in so many ways so much. And now it is clearly even more true — you can give me nothing now yet I love you so that you stand in my way of loving anyone else — but I want you to stand there. You, dead, are so much better than anyone else alive.

I know you will assure me that I am foolish and that you want me to have full happiness and don't want to be in my way. I'll bet you are surprised that I don't even have a girlfriend (except you, sweetheart) after two years. But you can't help it, darling, nor can I — I don't understand it, for I have met many girls and very nice ones and I don't want t

The chance is high that the truth lies in the fashionable direction. But, on the off-chance that it is in another direction — a direction obvious from an unfashionable view of field theory — who will find it? Only someone who has sacrificed himself by teaching himself quantum electrodynamics from a peculiar and unfashionable point of view; one that he may have to invent for himself.

The 'paradox' is only a conflict between reality and your feeling of what reality 'ought to be'.

If we want to solve a problem that we have never solved before, we must leave the
door to the unknown ajar.
