If we assume we've arrived: we stop searching, we stop developing. - Jocelyn Bell Burnell

Science doesn't always go forwards. It's a bit like doing a Rubik's cube. You sometimes have to make more of a mess with a Rubik's cube before you can get it to go right. You build up this picture of what there is and you believe it to be true and you work with this picture and you refine it but sometimes you have to abandon the picture. Sometimes you discover the picture you thought you had, that everybody thought we had, actually turns out to be wrong.

One of the things women bring to a research project, or indeed any project, is they come from a different place, they've got a different background. Science has been named, developed, interpreted by white males for decades and women view the conventional wisdom from a slightly different angle — and that sometimes means they can clearly point to flaws in the logic, gaps in the argument, they can give a different perspective of what science is.

Looking at the universe as a whole; cosmology, the birth, life and death of the whole universe, we used to have a nice simple model. Then we had to add things like dark energy, and our nice simple picture is getting messier and messier and messier.
