[Editor’s note: While your Flavorwire editors take a much-needed holiday break, we’ll spend the next two weekends revisiting some of our most popular features of the year. This post was originally published November 8, 2011.] Back in 2007, after spying a colleague with DNA-inspired ink at a party, Discover Magazine’s Carl Zimmer asked his blog readers whether any of the scientists among them were sporting similar tattoo odes to their work. Perhaps surprisingly, the response was overwhelming. “Without intending it, I became a curator of tattoos, a scholar of science ink,” he explains. “Tattoo enthusiast magazines called to interview me. All in all, it was a strange experience; I have no tattoos of my own and no intention of getting any. But the open question I posed brought a river of pleasures.” A collection of the photos that Zimmer received as a result of his query — which range from a tattoo of Darwin’s finches to a pair of colorful odes to Halley’s Comet — were published earlier this month in a new book called Science Ink: Tattoos of the Science Obsessed.
