who will generate all that power?


It was the kind of thing my father would have talked about: "What makes it go? Everything goes because the sun is shining." And then we would have fun discussing it:

"No, the toy goes becaues the spring is wound up, I would say.

"How did the spring get would up" he would ask.

"I wound it up"

"And how did you get moving?"

"From eating"

"And food grows only because the sun is shining. So it's because the sun is shining that all these things are moving" That would get the concept across that motion is simply the transformation of the sun's power.

From "Surely, You are Joking, Mr Feynman"
