> Biology is unusual among sciences in that a five year old can ask questions it can't answer. You can do this in a lot of fields, but you're right, Bio is one where it's very easy to do. I'm always struck by the 'pathways' side of mol-bio. It's not easy, but many grad students can come up with experiments that will lead to discoveries of new signaling pathways inside a cell. I'm sure someone has done a census of the number of pathways in their particular cell, but for all cells? It must be a gigantic number of proteins that interact. And I'd hedge that we're no where even close to knowing how they all interact
