It appears, Prof Emeritus of the Lucasian Chair, Stephen Hawking,
has passed aged 76.
Ave, Prof Hawking!

2 years to live, they said.
55 years later, called it a day, and what an innings!
His many great lectures, books etc (often team-up with Leonard Mlodinow)
such as "A Brief History of Time", "The Grand Design", "How To Communicate Science To A General Audience, A Primer" (informal 'manual', which is awesome)
or, the lecture "Philosophy is Dead", etc,
are well known, almost as much as his distinctive voice and sense of humor.
Perhaps what I will remember most,
is the letters between Prof Hawking and Prof Bartlett,
talking of futures-modelling etc.
Prof Hawking made some interesting reflections on the trickiness of modelling innovation,
and both made some arguments of EMERGY.
