As I sit at my table, for days, months, years, slowly adding new words to the empty page, I feel as if I am creating a new world, as if I am bringing into being that other person inside me, in the same way someone might build a bridge or a dome, stone by stone. The stones we writers use are words. As we hold them in our hands, sensing the ways in which each of them is connected to the others, looking at them sometimes from afar, sometimes almost caressing them with our fingers and the tips of our pens, weighing them, moving them around, year in and year out, patiently and hopefully, we create new worlds. The writer’s secret is not inspiration – for it is never clear where it comes from – it is his stubbornness, his patience. That lovely Turkish saying – to dig a well with a needle – seems to me to have been said with writers in mind.

What is rewarding about the priesthood is, one, that you have an incredible privilege of being privy to some of the most extraordinary things about people. I mean, as their parish priest, you visit people who are sick, say, on their death bed and they tell you things that they probably have not shared with any other person. You are privileged to bring the Holy Sacrament to people at a time when they are probably at their lowest. But you also have the privilege of meeting up with people at their moment of great joy, when they are getting married, or when they have a child baptized.

There was no school to attend or field to learn what today is known as ‘software engineering’ or ‘systems engineering.’ When answers could not be found, we had to invent them; we were designing things that had to work the first time, and our systems had to be ‘man-rated.’ Many on the team began as fearless 20-something-year-olds. The greater the challenge, the more fun we had. And, yet, dedication and commitment were a given. There was no time to be a beginner. Learning was by being and doing, and a dramatic event would often dictate change.

I was living in survival mode when I was young. I'm now trying to teach the people to live in a mentality that they can be whatever they want to be even though the situation around them is hopeless.

I was really proud that it was my stars that had convinced the prize committee that there was good physics in astrophysics.

I was very, very thorough, making sure I really understood how that telescope worked, and that it was working properly. I was quite convinced that I wasn't clever enough to be in Cambridge and would be thrown out at some stage. My policy was to work as hard as I could so that I'd know I'd done my best. We now label this as impostor syndrome, but we didn't recognise, and certainly didn't name it, back then.

Occasionally there would be something I didn’t recognise and I’d record it with a question mark or, as a joke, LGM for Little Green Men. It was easier than saying “you know that funny pulsing source at right ascension 1919, declination plus 20”. So, it became LGM.

From one particular piece of the sky an unclassifiable signal sometimes recurred and my brain started to say: “You’ve seen something like this before, haven’t you? You’ve seen something like this before from this bit of the sky , haven’t you?” I got out previous recordings from that bit of sky. It often wasn’t there, but when it was, it was keeping its place amongst the stars.

My contemporaries were more upset about the Nobel than I was not to be recognised. One of them labelled it the 'No-Bell' prize! But it was fine by me. There's no Nobel Prize in astronomy and I was really proud that it was my stars that had convinced the prize committee that there was good physics in astrophysics.

The next generation of telescopes will see millions of events per night with computers that sift through huge amounts of data. If we had had access to a computer, we would never have programmed it to look for something so unexpected. How do you pick up the things you don't know exist, the things you can't tell it to look for? My project was to study quasars, and then we accidentally stumble over these things called pulsars. They were totally unexpected, totally unknown – and it's been huge fun.
