Sir Patrick Moore died earlier today. At 89 he'd had a good innings, as they say.
Moore, like many astronomers, was an eccentric - in his case, it took the form of strange beliefs about the forrins, the women and the metric measurement system - but I've begun to believe that society subtly but firmly canalizes famous scientists into eccentricity.
As a kid I used to watch Moore on The Sky At Night with my dad, who was a member of the British Interplanetary Society. I can't claim that he changed my life in a fundamental way, but like all great broadcasters, he certainly had an effect. I wish there were more of them around today.
