Just wondering... when did that metaphor get started at VPRI? The first time I had heart you reference the t-shirt metaphor was October 2009 [1]. I remember joking about it on Lambda the Ultimate in April of 2009 [2], and my joke was actually based on a presentation given by the head operations physicist of the Relativistic Heavy Ion Collider project at BNL, Todd Satogata [3]. He gave a talk about how you can buy a t-shirt with Maxwell's Equations on it and it pretty much describes the whole universe. But he said his goal was to unify the strong force and weak force and come up with a new t-shirt, and make millions of dollars and become famous. When I heard that you were interested in Maxwell's Equations for Computer Science, I immediately made the connection to Todd Satogata's BNL speech (I've heard him give roughly the same pitch in other speeches many times), so that is why I made the joke about printing Maxwell's Equations for Computer Science on a t-shirt.
