Stephen Hawking, R.I.P.

In honour of Dr. Stephen W. Hawking’s remarkable work and (even less likely) long life, Albert Einstein’s birthday, Hawking’s status as Distinguished Visiting Research Chair at Waterloo, Ontario’s Perimeter Institute (PI), and Pi Day (3.14), please join me in a slice of pi/e (preferably at 1:59). You may also remember Hawking from his interest in Homer Simpson’s theory of a donut-shaped universe.
