Brainstorming Session

Right. So I have a few ideas. Obviously the first thing that came to my head was architecture, but I wanted to go a bit deeper than that! I've been researching algebraic structures, crystal structures and more. I'm thinking about the body and it's different kind of structures like muscles, bones, skin, organs.. and the millions of other things within the body also. Deeper again I'm thinking about human cells and the different components that make up the cell like the cell wall, chromosomes, the nucleus, ribosome's and the rest. I'm also looking at the structure of DNA. How it's formed, how it functions and how it replicates. It's really fascinating to be honest going into so much detail about it. Now to pick ONE!
