I've seen various shirts with physics and math written all over them. The most common one is the shirt with all the Maxwell equations written and "... and there was light". I never had the desire to own such shirts before.... till now. During my trip to the Kennedy Space Center this past December, I came across this t-shirt that made me laughed. Plus, it was also on sale. So I couldn't resist. A close-up of the equations (which are badly formatted, I must admit): The back has the explanation of what the equations describe: I haven't worn this yet, but I'm sure I'll look like a total geek when I do. Zz.
