When I have a lot of pain, I try to confuse my mind to forget about the pain and think about the distance. I don't want pain to be in my mind, because I'd really lose focus on running. After winning, you won't have that pain, but it comes later. The marathon is hard; the second day, you don't go up or down stairs.

I want my readers to laugh sometimes. Many readers in Japan read my books on the train while commuting. The average salaryman spends two hours a day commuting and he spends those hours reading. That’s why my big books are printed in two volumes: They would be too heavy in one. Some people write me letters, complaining that they laugh when they read my books on the train! It’s very embarrassing for them. Those are the letters I like most. I know they are laughing, reading my books; that’s good. I like to make people laugh every ten pages.

I just like to get to the start line knowing there was nothing else I could have done, that there wasn't a single session I didn't give 100 per cent. The physical certainty means you can relax mentally and let the performance come.

Being a scientist is about resilience because science is exploring the unknown, just as an immigrant is exploring the unknown. In both, you are on an uncertain journey and you have to find your own North Star.

Yes, in 2018, I was awarded the Breakthrough Prize for the discovery. I was a bit dumbstruck, never expecting that kind of thing to happen. I was keen that the money should be used well and the best way to do that seemed to be to encourage a more diverse research student population from under-represented groups.

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.

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.

They have a lot of extreme physics going on inside them and scientists use them to test theories of relativity on a cosmic scale. Einstein’s theories are checking out pretty well so far.

Tony was cautious. He suspected I’d wired the radio telescope up wrong. So we checked on another radio telescope on the site. The thing was pulsing nicely on mine but as we stood by the pen recorder of this other telescope, nothing happened. It was a horrible moment. And suddenly there it was, five minutes later because we had miscalculated when the telescope would see it. If we’d miscalculated by 25 minutes, we’d have all gone home and the story would be different.

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