In 2007, science writer Carl Zimmer wondered how common science tattoos were. He said this on his blog, and the response was massive and ongoing. That grew into a completely new blog, and Zimmer became known as the guy who collected science tattoos. Now he has a book of science tattoos called Science Ink: Tattoos of the Science Obsessed. The New York Times has a slide show featuring some awesome examples from the book. The tattoo shown belongs to a Princeton graduate student in molecular biology. Link -via The Loom
