Tipping a Waiter: You’re Doing it Right
Richard Feynman was damn witty. He once noted that he wished to memorize Pi all the way up to the 762nd place, because at that point begins a series of six nines in a row.
The Feynman Point, highlighted in red, was amusing for him so that he could recite the digits up to that point, and then say “nine-nine-nine-nine-nine-nine and so forth,” thus implying that Pi was rational.
How to Easily Memorize e to Fifteen Decimal Places
See that picture? It’s a 20 dollar bill, so “2” is the first digit - throw down a decimal after it.
Andrew Jackson was our seventh President, so put a “7” after that - 2.7
Jackson was elected in 1828, so put down “1828″ next. Since he served two consecutive terms, put “1828″ a second time. We’re now up to 2.718281828.
Now pay attention to the red square. The diagonal creates two congruent right triangles with angle measures 45, 90, and 45. So, add on 459045 to get 2.718281828459045. And that’s e to 15 places.
