Stephen Hawking exerts his own gravitational pull on Harvard audience.

"It is the past that tells us who we are. Without it, we lose our identity." Faculty and students packed into Sanders Theater on Monday, April 18, for the The 2016 Morris Loeb Lecture in Physics, delivered by Professor Stephen Hawking. Hawking declaimed on the history of physics, and its relation to his work to understand the phenomenon of black holes.  The event helped inaugurate the Harvard Black Hole Initiative, in which HistSci Department faculty member Peter Galison is a founding member.
