You have to love Zero's theory. Take your pencil and drop it on the table. Now, remember that clunk and look at the pencil on the table - that, did not just occur.
The theory is that for it to fall, it has to fall half way and to fall it goes half way again and again never reaching the other surface.
Have fun with that one.
Yeah, Zeno's Paradox. In order for you to get anywhere, you have to pass through an infinite number of halfway points.. I believe I read somewhere the resolution of this apparent paradox, but I'd have to go look it up again, and besides, I'd never get there..
The Greeks of his day were not comfortable with the concept of infinite series, and produced several fallacies along these lines, with Zeno's being the most well-known.
