When I was a physics major in the late 1970s, my very few fellow female students and I had high hopes that women would soon stand equal with men in science. But progress has proved slower than many of us imagined.

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

Almost all major scientific projects today are huge collaborations, yet we still have this public obsession with the idea of the individual scientific genius. One of my goals as a science communicator is to celebrate the collaborative dimensions of science, which I think will be critical for facing the ecological and resource challenges ahead. In a sense, we are all corals now.

Wave particle duality is a core feature of our world. Or rather, we should say, it is a core feature of our mathematical descriptions of our world. But what is critical to note here is that, however ambiguous our images, the universe itself remains whole and is manifestly not fracturing into schizophrenic shards. It is this tantalizing wholeness and the thing itself that drives physicists onward like an eternally beckoning light that seems so teasingly near. It is always out of reach.

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.

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.

Computers are very powerful tools, but in the simulated world of the computer, everything has to be calculated.
