One of the world's greatest scientists, Stephen Hawking, has passed away.  We have lost a great man who helped advance our understanding of the universe.  Though he had the great challenge of being confined to a wheelchair due to ALS, that did not stop Hawking from pushing his mind from pushing beyond what his condition had given his body.

One of the best references- and tributes to- I have seen of Hawking is in the Hyperion Cantos, with the Hawking Drive.  Its a great way to tie in a famous scientist, and now for me, the Hyperion Cantos will be forever be a tribute to Hawking.

May the Force be with you, Stephen Hawking.
