I'm reminded of a T-shirt company that was around when I was in college, named
"Outer products". They had various math and physics related shirts, for example
with Maxwell's equations (your choice of differential or integral form). Also one
with the first 4 lines of the Odyssey.
For computer geeks they had quite a bunch, including this particularly cryptic one for
COBOL programmers
