" "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.

About Richard Feynman
Richard Phillips Feynman (May 11, 1918 – February 15, 1988) was an American theoretical physicist. He is known for the work he did in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, and in particle physics, for which he proposed the parton model. For his contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga. Feynman developed a widely used pictorial representation scheme for the mathematical expressions describing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime, Feynman became one of the best-known scientists in the world.

Additional quotes by Richard Feynman
If a Martian (who, we'll imagine, never dies except by accident) came to Earth and saw this peculiar race of creatures - these humans who live about seventy or eighty years, knowing that death is going to come - it would look to him like a terrible problem of psychology to live under those circumstances, knowing that life is only temporary. Well, we humans somehow figure out how to live despite this problem: we laugh, we joke, we live.
If we try to say how big a photon is, or how it's spread out, or what it looks like, we're going to get into some difficulty with some experiment. It isn't going to behave that way you'd expect. ...[I]t's going to be impossible for me to tell you how big a photon is, where it is... Nevertheless... I'll tell you a series of crazy rules by which you can tell exactly what will happen in any experiment with photons... without ever being able to say what a photon looks like... in the sense of some sort of model of waves in space. ...And so to make a complete theory, we cannot do it with a model. We can only make an incomplete theory and what my purpose is today is to tell you the complete theory, not the incomplete approximations...
