Knowledge isn’t free. You have to pay attention.
Unknown (often misattributed to Richard Feynman)
The meaning of the quote
On February 11, 1986, physicist Richard Feynman sat at a hearing table in Washington with a glass of ice water in front of him. The space shuttle Challenger had broken apart 2 weeks earlier, 73 seconds after launch, killing all 7 people on board.
When a piece of the rocket booster’s joint came around the table, Feynman pulled out its rubber seal, squeezed it in a small clamp and dropped it in the ice water. The rubber came out still squashed. In the cold, the seal couldn’t spring back into shape, and launch morning had been colder than any shuttle launch before it.
Engineers had warned NASA about cold seals the day before the launch, and fellow commission member General Donald Kutyna had nudged Feynman in that direction. Instead of taking the reports’ word for it, Feynman tested the rubber himself.
Nobody has traced the quote to anything Feynman wrote or said, but it sums up how he worked.
The quote plays on the word “pay.” Information is free. Anyone can open a video on how a car engine works or read an article on the French Revolution without spending a cent. Knowledge costs focus, and you pay for it every time you look closely and stay with something after it gets boring.
Feynman learned this from his father. In the book What Do You Care What Other People Think?, he remembers another kid pointing at a bird and asking him its name. He didn’t know, and the kid teased him that his father taught him nothing. On their walks, his father would name a bird in several languages and then explain that knowing every name tells you nothing about the bird, only about what people call it. He’d finish with this:
“So let’s look at the bird and see what it’s doing—that’s what counts.”
Action steps
Paying attention gets easier when you stop splitting it. Use these the next time you sit down to learn something.
- Leave the phone in another room. A lesson and a group chat both want your attention, and the group chat usually wins.
- Look past the name. When you meet a new word like “photosynthesis,” ask what is going on inside the plant. If all you can do is say the word, you only know the name of the bird.
- Explain it out loud. Teach it to a friend or a younger brother or sister in plain words. The spot where you get stuck shows where your attention slipped.
Anyone at that hearing table could have asked for a glass of ice water. Feynman was the one paying attention.
About the author
Long before he won a Nobel Prize, Feynman was a kid in Far Rockaway, New York, with a home lab and a name around the neighborhood for fixing radios. In the book Surely You’re Joking, Mr. Feynman!, he remembers a man who doubted a small boy could fix his roaring set. Feynman paced back and forth in front of it until the man asked what he was doing. He said he was thinking, and then he fixed it. The man went around telling everyone:
“He fixes radios by thinking!”
During World War II he worked on the atomic bomb at Los Alamos, where he taught himself to open his colleagues’ safes by taking apart his own lock to see how it worked.
In 1965 he shared the Nobel Prize in Physics with Julian Schwinger and Shin’ichirō Tomonaga for work on quantum electrodynamics, the theory of how light and matter interact.
Feynman died on February 15, 1988, 2 years after the ice water hearing. What Do You Care What Other People Think? came out the same year, and in it you can read both his father’s bird lesson and his own account of the Challenger hearing.
