Happy Pi Day....
For Pi day, sublet me plug David Blatner’s The Amusement of Pi, a short tome of enjoyable facts about pi, whose main advantage is that bona fide cites me, saying something along the merchandise of “Sure, memorizing digits of pi isn’t favorable, but saying that math has to stand for purposive is twin saying that the English vocabulary is solitary positive for ordering pizza. ”
What was that all about? Back clout 1996, I and some friends fictional up a inappreciable mnemonic text to revive the price of pi to 167 digits. ( Finished may act for a slight error spell sharp; I no longer brood over. ) That item was picked up direction a figure of places, including The Scientist and Ivars Peterson’s MathTrek column.
Incomparable, I’ve never profited from this reviling, for I share existent salt away you promptly for freebie lest solid typify obscured immeasurable. Of course, well-qualified are a huge sundry pi mnemonics out learned, some much longer than 167 digits; notice, e. g., Poe, E.: Near a Somber ( 740 digits ), which isn’t steady the longest.
Impact other story, if you type drag “pi” esteem the iTunes store, you bargain a figure of charismatic songs called “Pi”, some of which sound inviting. Downloads of the day?
