I’m still something of a Stephen Hawking fan, so I think this news is very cool. ”Prof Stephen Hawking has been honoured on a new 50p coin inspired by his pioneering work on black holes.” What better way to pay tribute  to the major roll hawking played in both opening up physics to a wider audience and improving the representation  of disabled people in the mainstream media? I  can’t  wait to have a few new 50p pieces in my wallet, although perhaps a  6.674p piece might be more appropriate.
