I wondered if I had been missing something interesting about the scientists I spent so much time with, or if I was just mistaking two tattoos for a trend. So I posted the question on my blog at Discover Magazine, The Loom. I immediately received a comment from a scientist who said that he knew an old geneticist with a DNA tattoo as well. Then a physicist wrote in. "A former student got a tattoo of a cartoon atom on the back of one of his legs," he recalled. "He told me that the first day after he got it, he went to rugby practice, and was showing it to someone when one of the seniors on the team (also a physics major) walked by. The senior looked at it, said 'Oh, please. The Bohr model?' and walked off."
That's from Carl Zimmer's column in the Guardian, which he pointed to in response to a tweeted question:
