# Happy Pi Day!

At Towerhill, we so appreciate our genius mathematical candidates who truly reinvent and shape the scope of technology! In honor of Pi Day, we found THIS great article from Mother Nature Network (MNN) detailing eight super interesting (and somewhat bizarre!) facts about our favorite irrational number!

While sequential dates, like Dec. 13 of this year (12/13/14), are appealing to number nuts and the superstitious, March 14 takes date-play a step further. The month and day (3/14) that represent the ratio of the circumference of a circle to its diameter (3.14) has become an annual celebration of all things pi. That’s right, Pi Day.The first widely-attended Pi Day celebration was organized in 1988 by physicist Larry Shaw, also known as the Prince of Pi, at the San Francisco Exploratorium. It has become a yearly tradition that includes pi activities, a circular procession (a pi parade, if you will), and then, naturally, the eating of pie. In March 2009, the U.S. House of Representatives made it official when it passed a non-binding resolution (HRES 224) recognizing March 14 as National Pi Day.So in celebration of the mathematical constant with a cult following, we are pleased to present some of the odder facts about 3.14.1. Before Watergate, there was (almost) Pi-gateIn 1897, the Indiana General Assembly nearly passed a bill adopting 3.2 as the exact value of pi at the behest of an amateur mathematician. Fortunately, a savvy math man from Purdue University, who was by chance visiting the legislature, intervened and prevented the bill from becoming law.2. Rivers bend to piThe way a river meanders is described by its sinuosity; the length of its winding path divided by the distance from the source to the ocean as measured in a straight line. Strange as it may be, the average river has a sinuosity of around 3.14.3. Pi is irrational and transcendentalFor those who are drawn to complicated partners, pi – which is classified as both irrational and transcendental – is for you! Pi is known as an irrational number because it can’t be written as a ratio or simple fraction; while 22/7 is close, it is not exact. It is also a transcendental number, meaning that it is not algebraic – it is not a root of a non-constant polynomial equation with rational coefficients.For a translation of that last sentence, let Australia’s Numeracy Ambassador, Simon Pampena, explain:4. Some people’s obsession with pi is nearly as infinite as the constant itselfAs an irrational and transcendental number, pi will continue infinitely without repetition or pattern; it has been calculated to more than 1 trillion digits beyond its decimal point. This makes number enthusiasts very excited. While mere math mortals know pi as 3.14159, some super pi zealots memorize the value of pi to tens of thousands of digits. According to the Pi World Ranking List, Chao Lu holds the world record with his recital of 67,890 digits.5. Pi Phone is a thingIf the sound of pi’s endless digits being read to you out loud sounds exciting (and who are we to judge?), call (253) 243-3116 and listen in. The pi Phone Project was created by pi fan Christopher Poole and will deliver the digits for as long as you’re willing to listen. Bonus for Apple users: you can tell your friends you called pi Phone on your iPhone.6. The freaky realization that pi is pieEverybody has a good time making homophone jokes about pi and pie; it’s why pie is the unofficial foodstuff of Pi Day. But consider this (cue “Twilight Zone” theme): 3.14 seen in a mirror reads PIE.7. Pi inspiresIn Greek mythology, Euterpe may have been the muse of music, but for some math-loving musicians, pi serves to inspire. Austin-based musician Michael John Blake, for example, created the musical representation of pi (video below) to 31 decimal places at 157 beats per minute (which, as it turns out, is 314 divided by two).8. There is an exact best time to celebrate Pi Day

Because if you’re celebrating 3/14 for the sake of pi, you might as well go all out and time it to its most common approximation, 3.14159 … meaning, break out the party hats and pie on 3/14 at 1:59.Happy Pi Day!

We love Pi! Pi Day often evokes memories of high school math class and all the delicious pies we would have in celebration! How did your office celebrate Pi Day? Do you have any awesome Pi Day traditions to which you adhere? Leave us all your best stories in the comments!
