Brian Greene (author of The Elegant Universe) just posted this photo on his Facebook wall with the following description:
An action shot from Saturday's Origins Symposium, shows the civil way scientists debate. On the right, that's Bill Nye ("The Science Guy") restraining Neil Tyson, as I offer my perspective.
There's probably some context that would make this make sense, but really, just seeing three of our generation's most iconic scientists screwing around like kids is enough to put a big fat grin on your face. Okay, guys, now get back to work and fix our planet, please. [Facebook]
