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.
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.
I know from another pulsar astronomer who won the Nobel that you get no peace. You're asked about every subject under the sun. It quite wrecks your life.
In the field of astronomy in the mid-'60s, quasars were very sexy objects - gigantic, star-like masses about which little was known. I was a graduate research student at Cambridge working towards my Ph.D. and chose quasars as the subject for my thesis. Part of my project involved surveying the sky for them using a radio telescope.
I believe it would demean Nobel Prizes if they were awarded to research students, except in very exceptional cases.
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.'
People are suspicious of science. They see it as being responsible for problems like the degradation of our climate. There is also a strand in society that says physics is terribly hard.
Although we don't know what is outside our universe, astronomers still wonder. Several pictures of what there might be have been dreamed up. An interesting one, called multiverse, has lots of universes. Picture it as a foam of bubbles. Our universe would be one bubble, and we'd be surrounded by lots of other bubbles.
Radio astronomers are aware in the back of their minds that if there are other civilizations out there in space, it might be the radio astronomers who first pick up the signal.
I am very conscious that, having worked part time, having had a rather disrupted career, my research record is a good deal patchier than any man's of a comparable age.
As observatory architect, my dad was partly concerned with the maintenance of them all. I used to go with him on site visits quite often, from age 7 or 8. I have memories of crawling through the rafters of the old building, trying to find where the leak in the roof was.
There are some countries where there is not an issue with women in physics. Malaysia, for example, has physics departments where 60 per cent of undergraduates are female, and France and Italy are strong, too. It is not about ability but more about what the culture says is appropriate.
People from different backgrounds approach a subject in different ways and ask different questions.
Demarcation disputes between supervisor and student are always difficult, probably impossible to resolve... it is the supervisor who has the final responsibility for the success or failure of the project.
It's now widely recognised that a diverse research group is usually stronger, more creative, and more robust and flexible. Such a group usually copes better in a downturn.
I'm the eldest of four children: a brother next after me and then two sisters.
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.
Throughout my working life, I've been either one of very few women or the most senior woman in the place.
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.
We didn't get television until quite late, the late fifties, but we had radio, and I can remember listening to the Korean War news on the radio with my family and sensing the anxiety of the adults although not understanding it myself, not understanding exactly what was going on.
