The beautifully weird world of scientists' tattoos (check these out)
It took about a year to bring everything together for the book. First, the book designers and I had to let people know we were starting the project and ask for high-resolution photographs. We got a huge number of pictures in response, and in the end we selected about 300 images for the book. Then it came time for me to write the captions, which I approached as miniature essays. It took a lot of research to write the text — I communicated with scientists to get the stories behind the tattoos and did my own reading to learn about everything from Central Asian mummies to quantum physics.
