And none of them were taking any notes.
Feynman was lecturing and I couldn't, of course, understand anything.
It was really high level quantum physics.
But towards the end, he looked up at the clock and he said, look, we've only got...

And this particular problem we're talking about, he said, there's two ways of tackling it.
