I’ve been mortally opposed to the so-called life-and-death committees that were instituted. When there were many more patients that needed to be dialyzed, and not enough artificial kidneys available, you had the institution of the life-and-death committees. ... Depending on the answer to these questions, he could be dialyzed. Otherwise, he could go to hell. I’ve been mortally opposed to that.

Brummies have adopted the sense that we live in a shit-hole, but in terms of green space, culture and community, it’s unrivalled.

We disagree. We believe that a policy of portfolio concentration may well decrease risk if it raises, as it should, both the intensity with which an investor thinks about a business and the comfort-level he must feel with its economic characteristics before buying into it.

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.
