In college, I was once wearing a t-shirt with this picture on it while visiting one of my physics professors at his office. The physics department secretary, a fifty-something woman, told me that she was from Ulm–Einstein’s birthplace–and that they have a statue of Einstein there in the famous sticking-tongue-out pose. She also told me that she had always hated that picture because it made him seem undignified, and she hated that her hometown had erected a statue of it.
I always figured that Einstein was a guy who knew the inherent limits of dignity. In high school I had a great sepia-tone poster of him trying to ride a bicycle. Here’s a sort of version http://whyfiles.org/052einstein/
The picture of Einstein sticking his tongue out is real? I’d never seen it before I got online and only see it as an avatar at various messageboards, so thought it was a photo manipulation until now. Huh. Learn something new every day.
