There's some evidence that if you're recruiting, you tend to recruit a mini-me. Then you have a very comfortable group round a table. You all think alike. You agree. People are arguing that the banking crisis was because too many of the relevant bodies were thinkalikes, and that if they'd had more diversity, maybe it wouldn't have happened.

The universe is very big - there's about 100,000 million galaxies in the universe, so that means an awful lot of stars. And some of them, I'm pretty certain, will have planets where there was life, is life, or maybe will be life. I don't believe we're alone.

A search for truth seems to me to be full of pitfalls. We all have different understandings of what truth is, and we'll each believe - or we are in danger of each believing - that our truth is the one and only absolute truth, which is why I say it's full of pitfalls.

If you look at other countries, you'll find lots of girls doing physics, engineering, and science. It's something to do with the kind of culture we have in the English-speaking world about what's appropriate for each of the two sexes.

Arguably, my student status and perhaps my gender were also my downfall with respect to the Nobel Prize, which was awarded to Professor Antony Hewish and Professor Martin Ryle. At the time, science was still perceived as being carried out by distinguished men.

When I went to my local grammar school, Lurgan College, girls were not encouraged to study science. My parents hit the roof and, along with other parents, demanded a curriculum change.

My generation was the turning point. Women older than us didn't expect to have jobs or careers; those younger did. But we were where it was changing - which is interesting but uncomfortable.

We live inside our universe and cannot get a bird's-eye view of it from outside. And we cannot even see all of our universe. Distant parts of it are expanding away from us so fast that they are invisible; they go faster than the speed of light. Having bigger telescopes to see fainter stars will not help us here: invisible is truly invisible.

I'm one of the few women in science. I have pioneered that. One of the things I worry about is what that pioneering has done to me. I have had to fight quite hard most of the way through life.

In Quakerism, your understanding of God is revised in light of your own experience, while in research science, you revise your model in light of data from experiments.

Some of the hydrogen in your body comes from the Big Bang, and when you see a kid walking down the street with a helium balloon, you can say, 'There goes some of the primordial universe.'
