Mathematical fumblings: the Klein j-invariant and near-integers
On Google+: Why e^(pi * sqrt(163)) is almost, but not quite, an integer, and how it relates to a pretty function called the Klein j-invariant. With some pictures, and bonus references to Ozma of Oz and an April Fool prank by Martin Gardner.
