factoids

My uneven collection of facts, quotations, and other miscellaneous scraps, that don’t naturally fit anywhere else. I used to keep them in a shoebox, until I discovered the Web.

About binomial theorem I’m teeming with a lot o’news,
With many cheerful facts about the square of the hypotenuse.

— W. S. Gilbert, The Pirates of Penzance, 1879
