xkcd is wonderful (though once in a while I don't get it at all, when it involves too much insider computer knowledge). And speaking of approximations, an MIT alum told me around 1993 that pi seconds ~ 1 nanocentury. --Dan Rich wrote: << Today's XKCD cartoon has a nice collection of approximations. http://xkcd.com/1047/ There's the ancient expression 6 pi^5 for the mass ratio of the proton to the electron, and the more accurate (e^8 - 10)/phi. Robert Munafo & REIS are at least partially responsible.
