too much brainpower - gravity affected

was dorking out and looking at photos of the great A. Einstein and found this superb photo of the man with Robert Oppenheimer.

In the rarified atmosphere of world-changing physicists and mathematicians, Oppenheimer was a genius among geniuses.

Once, during his lecturing days, Oppenheimer was called out of town for a few weeks. He asked one of his colleagues to cover for him. He told his colleague to teach directly from the textbook, and answer questions as required. Piece of cake.

The colleague arrived to find that the textbook was entirely in Dutch. The colleague told Oppenheimer that he couldn't do it, the book was in Dutch. Oppenheimer replied, "Ahhh, but it's such easy Dutch."
