“After much consideration, I decided to get an atom tattoo. But what atom? Given that I’m an graduate student in organic chemistry at the University of Michigan, carbon seemed like the obvious choice. It also has the advantage of being small enough not to look too crowded. I went for a retro 50’s Jetsons sort of look. Believe it or not, the general shape (though not the coloring) is based on a piece of Microsoft Office clip-art.”
