Martin Rees, Astronomer Royal

Who is the cleverest person in Britain? When Gyles asked this question to readers of his columns last year, one name was mentioned more than any other; that of Martin Rees, Lord Rees of Ludlow, the Astronomer Royal. Lord Rees is one of the most distinguished scientists in the country, a former President of the Royal Society and a Cambridge fellow. He wrote the first papers on quasars (a type of black hole) and he, alongside other greats such as Dennis Sciama and Stephen Hawking, helped to develop our understanding of the origins of the universe. He is also, Gyles discovers, a man of incredible modesty who just got into science because "he wasn't much good at anything else".

This is a wide-ranging conversation which takes in not only Rees's childhood in Shropshire and early academic career, but also includes discussions of the big bang, the future of the earth, and what happens to scientists when they get old. Plus, there's a bombshell revelation about Sir Isaac Newton. This is one of our most profound and intelligent Rosebuds yet: which isn't surprising, given our guest. Thank you, Martin Rees.
