We may be celebrating Pi Day here at io9, but we would be irrational to deny that there’s more to mathematical interestingness than simply dividing an object’s circumference by its diameter. Here are seven numbers we love as much as pi.

A while back we had a post about how Happy Numbers and the Spiral of Four make up a sort of binary code for all numbers in existence. We thought that was all there was to say. How wrong we were! A reader wrote in, giving me more information on how his math class made Happy Numbers the naughtiest numbers in history.

Colonoscopies sometimes end with intestinal detonation, or what's known in more official circles as a "colonic gas explosion." Never heard of it? Neither had we. That was until last night, when a team of international researchers was awarded an Ig Nobel Prize in Medicine for advising doctors who perform such…
