“I’m currently a PhD student in chemistry, specializing in polymer synthesis. I got this tattoo at the very beginning of my graduate studies (almost three years ago), for many reasons (one of which was to keep me from ever backing out :)) The tattoo is of electromagnetic radiation that spirals into a polymer chain, which forms an “S” for entropy and then unravels … kind of how we all do.
