another one.. imagine a clock which second hand is so long that each tic at its outer edge travels a distance of 186,000 miles (in other words, the speed of light) and you are standing at the center of the clock on the second hand traveling with it watching the outer edge with a telescope... what would you see?

What I like about Feynman's intelligence is that he makes it possible to avoid being intimidated by all that tedious technical jargon and complex number crunching!
