It's amazing how quickly bad news circulates the globe these days. At the first hint of bad news it is there staring at you on a news feed somewhere. before you know it, even Wikipedia has been updated, usually before the news has had chance to sink in.
Physics was not really my thing in school, but over the decades I have become more and more interested in it. Most of this is down to Mr Hawking. More than physics, he was a force for good in the world and never missed the opportunity for a moment of fun it would appear. So it is sad to hear that he has died today. I can think of few really great minds in my lifetime and he is really the only one who springs to mind when I think about the word genius.
