Good morning, Whitewater.
Saturday in town will be mostly sunny with a high of forty six. Sunrise is 7:07 and sunset is 7:00, for 11h 53m 13s of daytime. The moon is a waning crescent with 41.6% of its visible disk illuminated.
It’s Pi Day today, and not just any Pi Day, but a particularly impressive one:
Saturday is Pi Day.
But not just any Pi Day.
It’s the mother of all Pi Days. Pi Day of the Century. Heck, Pi Day of the Millennium.
It’s 3-14-15 — as any good geek knows, a date that corresponds with 3.1415, the first five digits of the infinite number pi. That calendar coincidence has math fans practically wriggling with glee, not to mention those who just appreciate the whimsy of celebrating a number that sounds like pastry.
You might say that’s irrational. Mathematicians would agree.
And therein lies the delight of Pi Day.
You probably remember pi from grade school, but here’s a quick refresher: Pi is the number that approximates the ratio of a circle’s circumference to its diameter. In other words, if you divide the circumference of any circle by its diameter, you always get pi, an irrational number that starts with 3.1415 and goes on forever. It shares its name with the 16th letter of the Greek alphabet.
The idea of celebrating Pi Day on March 14 — coincidentally, Albert Einstein’s birthday — started in the 1980s. The first large-scale celebration was organized in 1988 at the Exploratorium museum in San Francisco, and Pi Day got a boost two decades later when the U.S. House of Representatives passed a resolution supporting its celebration in 2009….
Delicious.
