Well, I'd never really believed maths to be all that interesting, until Chris started explaining the infinite halves.
So,theoretically, you shouldn't be able to cross a room, because in order to cross half of the room, you have to cross half of that, and then half of that, and it could continue forever. It's rather simple to grasp, when you understand there is no YET possible way to travel a kilometer, before crossing half a kilometer. And so forth.
However, we can cross a room, even though with this theory, we shouldn't be able to.
It then makes me think about the halves and halves and halves that I have crossed, and when the number is infinite, in theory, I haven't travelled at all!
I'm standing still, and have been for eternity because I can not cross the room, can not get to the number underneath a whole...
Suddenly, I understand maths on a whole new level. It just confused the fuck out of me.
