When I was just a little kid, very small in a highchair, my father brought home a lot of little bathroom tiles--seconds--of different colors. We played with them, my father setting them up vertically on my highchair like dominoes, and I would push one end so they would all go down.
Then after a while, I'd help set them up. Pretty soon, we're setting them up in a more complicated way: two white tiles and a blue tile, two white tiles and a blue tile, and so on. When my mother saw that she said, "Leave the poor child alone. If he wants to put a blue tile, let him put a blue tile."
But my father said, "No, I want to show him what patterns are like and how interesting they are. It's a kind of elementary mathematics." So he started very early to tell me about the world and how interesting it is.Feynman's family had the Encyclopedia Britannica (remember those?) and his dad would sit Richard on his lap, and read to him.
We would be reading, say, about dinosaurs. It would be talking about the Tyrannosaurus rex and it would say something like, "This dinosaur is twenty-five feet high and its head is six feet across."
My dad would stop reading and say, "Now, let's see what that means. That would mean that if he stood in our front yard, he would be tall enough to put his head through our window up here." (We were on the second floor.) "But his head would be too wide to fit in the window."
Everything he read me he would translate as best he could into some reality.
It was very exciting and very, very interesting to think there were animals of such magnitude--and that they all died out, and that nobody knew why. I wasn't frightened that there would be one coming in my window as a consequence of this. But I learned from my father to translate: everything I read I try to figure out what it really means, what it's really saying.Of course, Feynman's father taught him more than how to translate from words to reality. He also taught him to go from reality to words.
My father taught me to notice things. One day I was playing with an "express wagon," a little wagon with a railing around it. It had a ball in it, and when I pulled the wagon I noticed something about the way the ball moved. I went to my father and said, "Say, Pop, I noticed something. When I pull the wagon, the ball rolls to the back of the wagon. And when I'm pulling it along and I suddenly stop, the ball rolls to the front of the wagon. Why is that?
"That, nobody knows," he said. "The general principle is that things which are moving tend to keep on moving, and things which are standing still tend to stand still, unless you push them hard. This tendency is called 'inertia,' but nobody knows why it's true." Now, that's a deep understanding. He didn't just give me the name.
He went on to say, "If you look from the side, you'll see that it's the back of the wagon that you're pulling against the ball, and the ball stands still. As a matter of fact, from the friction it starts to move forward a little bit in relation to the ground. It doesn't move back."
I ran back to the little wagon and set the ball up again and pulled the wagon. Looking sideways, I saw that indeed he was right. Relative to the sidewalk, it moved forward a bit.
That's the way I was educated by my father, with those kinds of examples and discussions. It has motivated me for the rest of my life, and make me interested in all the sciences. (It just happens I do physics better.)
I've been caught, so to speak--like someone who was given something wonderful when he was a child, and he's always looking for it again. I'm always looking, like a child, for the wonders I know I'm going to find--maybe not every time, but every once in a while.Update:
