Stephen Hawking will be remembered for many things, one of which is as a brilliant theoretical physicist, which is what I'd rather focus on. His Hawking radiation formula accurately predicts the decay/evaporation of black holes (specifically, the entropic principles thereof). The Penrose-Hawking theorems are also very important mathematical tools.

He authored the book (as well as many others),

*A Brief History of Time*, which became a bestseller for a record number of weeks, and introduced a new generation (myself included) of tinkerers to concepts of quanta, cosmology, and the like. The world owes a great deal to his humanity - disagreements about its course of direction aside, as we had no choice but to look at him as nothing more than a triumph.

You are appreciated.
