For most people, the major hurdle in grasping modern insights into the nature of the universe is that these developments are usually phrased using mathematics.

For me it's been very exciting to contribute to the public's understanding of how rich and wondrous science is.

In my own research when I'm working with equations, I never feel like I really understand what I'm doing if I'm solely relying on the mathematics for my understanding. I need to have a visual picture in my mind. I'm constantly translating from the math to some intuitive mind's-eye picture.

There are many of us thinking of one version of parallel universe theory or another. If it's all a lot of nonsense, then it's a lot of wasted effort going into this far-out idea. But if this idea is correct, it is a fantastic upheaval in our understanding.

One of the most interesting things about science fiction and fantasy is the way that the genres can offer different perspectives on matters to do with the body, the mind, medical technology, and the way we live our lives.

We have been talking about public engagement for a decade. For me it is about recognising that the mission of science has to be embedded within our culture - the direction in which science is going has to be determined by all of us, and so we need a dialogue with the public.

Science fiction, in its purest form, for me, it works the best when it's being used as metaphor to look at something from a one-step-removed process, to give a little objectivity and insight into something that, if you were applying it on the face of it, we'd all be too close to.

A poem in form still has to have voice, gesture, a sense of discovery, a metaphoric connection, as any poetry does.
