What stuff really is

At school we do science but it’s all about plants.  This is biology. But if you take biology and just look at it much more close up, you end up with chemistry. And if you go even more close up you end up with physics.

This is the kind of science I enjoy and I am trying to find out about at the moment: all the little particles and the spaces between them, and how they act around each other. So if you know about this sort of thing and you’d like to tell me some cool stuff, you can leave a comment! Thanks.
