Nanometers may be small, but they're not infinitely small, which is what infinitesimal means. They're barely even any closer to infinitely small than centimeters.

Well, FWIW, *both* of them are infinitely larger than infinitesimal despite the fact that nanometres are closer. So does this mean that the "infinity" between centimetres and infinitesimal is larger than the infinity between nanometres and infinitesimal? Hmmmmmm......

Also, imagine a line of people standing single-file, extending infinitely in both directions. There are, of course, an infinite number of people. Now, imagine each of these people is joined by a partner. Are there twice as many people now? Does this mean there are "2 x infinity" people? But surely you can't do that to infinity. Er...

Spoiler; I'm not a mathematician, and don't have the answers, I'm just throwing this out here for amusement. Though I guess someone who knows more about this than I do could explain it if they could be arsed.
