##### Today’s post looks ahead to tomorrow, pi day!

Tomorrow, March 14 is Pi Day, an annual celebration of the mathematical constant π (pi), which is the ratio of a circle’s circumference to its diameter. The trillion-digit ratio is rounded to 3.14.

Albert Einstein was born and Stephen Hawking died on Pi Day. But of course, there is more than coincidences on this mathematically based holiday. There are savings on, you guessed it, pies of all varieties. The discounts range from coconut cream to deep dish pepperoni. More on some of the discounts are listed below.

Here are some fun Pi Day facts from PiDay.org.

- Since the exact value of pi can never be calculated, we can never find the accurate area or circumference of a circle.
- Although Pi day is celebrated on March 14 (3/14), the exact time for celebration is 1:59 pm so that the exact number 3.14159 can be reached.
- There is an interesting reason why the name ‘pi’ was coined. Before the name pi came, mathematicians had to say a mouthful. The only descriptive phrase they could use was “the quantity which when the diameter is multiplied by it, yields the circumference”. Pi was named pi by William Jones, a not-so-popular mathematician.
- There is an entire language made on the number Pi. But how is that possible? Well, some people love pi enough to invent a dialect in which the number of letters in the successive words are the same as the digits of pi. But it is not just another nerd quirk that nobody knows about. Mike Keith wrote an entire book, called ‘Not a Wake’ in this language.
- The calculation of pi is a stress test for a computer. It works just like a digital cardiogram since it indicates the level of activity within the computer’s processor.
- William Shanks, a British mathematician, worked manually to find the digits of pi. He spent many years trying to calculate the pi digits by hand and found the first 707 digits. Unfortunately, the 527th digit he found was wrong, which made his efforts of finding the remaining digits useless because they were all wrong by default.
- Even comedians use pi to make people crack at their jokes. John Evans, a comedian, once said in his performances, “What do you get if you divide the circumference of a jack-o’-lantern by its diameter? Pumpkin π.”
