A joke

When I read this joke online and chuckled, I suddenly realized my arts and science education was not entirely for naught:

Werner Heisenberg, Kurt Gödel, and Noam Chomsky walk into a bar. Heisenberg turns to the other two and says, "Clearly this is a joke, but how can we figure out if it's funny or not?" Gödel replies, "We can't know that because we're inside the joke." Chomsky says, "Of course it's funny. You're just telling it wrong."

Looking for "Cochrane, Zefram"

The various research proposals linked-to on this site have been an invaluable weapon in my three-day-long battle against insomnia. It might just be a product of the late hour, but I think I've convinced myself that I comprehend most of it. Well, "ponderomotive forces" required a Wiki run. But solar shields at Lagrange points? Psssh. Easy stuff.
