You know that iconic photo of Albert Einstein sticking his tongue out? It just sold at auction for $74,324, and now belongs to a man in Great Neck, NY. Newsday reports that the expression was captured in 1951, and Einstein himself gave one copy (of the nine he requested) to American broadcast journalist Howard K. Smith with the inscription: "This gesture you will like, because it is aimed at all of humanity." It's the only time he ever came close to explaining his action in the photograph, and the new owner notes: "In the middle of a Communist witch hunt, here he is sticking his tongue out. I think he's telling us to buck authority." This is probably way more fun than owning those notes on relativity.
