Simple DNA gradually morphed and evolved, so that you had the coming into being of ever more complex and diverse creatures, until one day you wake up and find there are peacocks and giraffes. Nature is an open-ended experiment based on morphing a DNA code, and ours is an open-ended experiment based on morphing a crochet code.

I don't know of any science writing going on in women's magazines, unless you count medical stories about things like breast cancer. I still think there's a huge problem about how we can actively engage a wider range of women. I'm not saying women must be a separate audience - I'm just responding to the reality that the majority of people who do read science magazines are male. That's not a value judgment; it's a statistical fact.

I believe that there is a love that moves the sun and the other stars.

As a child it was clear to me that in some sense math was in the world around us. I became fascinated by what this means. When you look at the shape of the sun and the moon, they're circles, so every time you see a circular thing, there's pi embedded in it.

It turns out that hyperbolic structures are very common in nature, and the place where lots of people encounter them is coral reefs. Sea slugs, and a lot of other organisms with frilly forms, are biological manifestations of hyperbolic geometry, which is also found in the structure of lettuce leaves and kales, and some species of cactus.

This is what I call the "cosmological problem" of science. Science has the instrumental function that has given us computers and so on, but its cosmological function is to give us a picture of the world we inhabit as human beings, and on that level it's failing a vast number of people.

For ten years, I wrote regular columns about science for women's magazines, and to my knowledge I'm the only person in the world who can say that. This has no kudos in either the science-writing world or the academic world, but it's one of the most challenging things I've ever done. It's much harder to write about cosmology for a magazine like Vogue than for the New York Times, which I've also written for, because you have to imagine that on the page opposite there'll be an advertisement for eyeliner, or an article about the latest trends in skirt length.
