On the Pleasure of Finding Things Out: Richard Feynman in Conversation

About Richard Feynman

Richard Feynman (1918–1988) was an American theoretical physicist who won the Nobel Prize in Physics in 1965. He is equally famous for his physics and for his extraordinary ability to communicate the joy and strangeness of scientific thinking to non-scientists. His lectures at Caltech became The Feynman Lectures on Physics — still the most widely read physics textbook in history. He played bongo drums, cracked safes at Los Alamos, and explained quantum electrodynamics in the same afternoon.

This interview is adapted from the documentary "The Pleasure of Finding Things Out" (BBC, 1981), in which Christopher Sykes interviewed Feynman at length about science, teaching, and knowing.

The Interview

SYKES: "Professor Feynman, you're famous for being able to explain things clearly. But sometimes scientists are accused of making the world less magical by explaining it. What do you think about that?"

FEYNMAN: "I think that's completely backwards. My uncle — he was not a scientist — he told me that when you know what something is, you lose the wonder of it. He thought a scientist looks at a flower and sees only cells and molecules. But I see the same flower he sees. Plus I see something else. I see the beauty in its design, the amazing fact that it works at all, the extraordinary machinery in each cell. The fact that we know how the eye sees colour doesn't make colour less beautiful. It makes it more beautiful — because now you understand that beauty is what an extraordinarily complex machinery produces, apparently for no reason at all, for free."

SYKES: "For free?"

FEYNMAN: "For free. Nobody needed beauty. Evolution doesn't care about beauty. But here it is. Wouldn't that be strange if that were all there was to it — just molecules bumping into each other, and the result being something as extraordinary as consciousness, love, music? The mystery goes deeper, not shallower, when you understand more."

SYKES: "You've spoken about the difference between knowing the name of something and knowing it. Can you explain that?"

FEYNMAN: "My father. He taught me this. He would show me a bird and say — 'In English, that's called a brown-throated thrush. In Portuguese, it's called something else. In Chinese, something else.' And he said: 'Now you know nothing about the bird. You know only what humans in different languages call it. You don't know anything about what it does, how it lives, what it sounds like, what it eats, what it fears.' And he was right. Knowing the name is not the same as knowing the thing. This is the difference between science and the illusion of knowledge."

SYKES: "You've been involved in important work — Los Alamos, the Challenger investigation. Do you have regrets?"

FEYNMAN: "Los Alamos was necessary. That's what I told myself, and it's probably true. But the bomb was dropped on Hiroshima, and I celebrated. I'm not proud of that. I was twenty-seven years old and I had been working on a single problem for three years, and the problem was solved. And I felt something I am ashamed of. Later I was riding on a bus in New York and I saw a building going up and I thought: that building will fall down. That bridge will crumble. In twelve years, there will be nothing. Because I knew we had invented the bomb and the world would end. That feeling lasted about a year. Then you get back to life, because what else do you do?"

SYKES: "How do you think about certainty in science? You've famously said 'I don't know' very often."

FEYNMAN: "I was brought up to not know. That's the most important scientific education. If you think you know the answer, you stop looking. Science requires the permanent willingness to be wrong. Most scientists are wrong most of the time. The ones who make discoveries are the ones who are willing to be wrong one more time, in a new direction. Certainty is the enemy of discovery."

Key Analysis: What This Interview Reveals

1. FEYNMAN'S PEDAGOGY — the father's lesson about the bird illustrates the distinction Feynman drew throughout his life between nominal knowledge (knowing names) and real knowledge (understanding mechanisms and relationships). This distinction is directly applicable to study strategies.

2. THE QUESTION OF SCIENTIFIC WONDER — Feynman's reversal of the "science kills wonder" argument is one of his most famous contributions to science communication: scientific understanding adds layers of meaning rather than removing them.

3. HONESTY ABOUT LOS ALAMOS — the admission that he celebrated Hiroshima before feeling shame is unusual in scientists' public accounts of that period. It is an example of intellectual honesty applied to personal history.

4. UNCERTAINTY AS METHOD — "Certainty is the enemy of discovery" is Feynman's epistemological core: genuine scientific thinking requires maintained uncertainty, not the performance of confidence.
