Have you experienced the sensation that occurs when you start thinking about something that is really really small? Then start thinking of the things that make that up?
I talked the other day about getting a sense of our place in the Universe by thinking about the immenseness of the solar system, then the galaxies and then the Universe itself. Well the same thing happens when you start thinking about the really small things. And then the things that make those up. And so on.
When you get down to a quantum level things start to get really strange. Things that make you twitch a little. Cringe even. It goes against all you know to be true in your scientific gut, things like a particle being in two places at once. Just how is that possible? Unless.. Unless..?
Anyway have a look at the the eye of science site
