Happy Pi day to all the math lovers 🙂 Pi day is celebrated across the world on March 14th (3/14). Let us celebrate Pi day by looking at some interesting fun facts involving this irrational number:
1. Exploratorium in San Francisco celebrates Pi Day on March 14th (3/14) at 1:59 pm PST to celebrate the number 3.14159.
2. There is a Guinness World record for memorising and reciting the digits of Pi (π). Rajveer Meena from India wore a blindfold for almost 10 hours and recalled 70,000 digits of Pi. This was on 21st March 2015.
3. Pi(π) has about 6.4 billion known digits. That’s 6,400,000,000 digits!! It will take you approx 133 years to recite them if you were to recite them without stopping.
4. William Jones created the symbol of Pi in 1706.
5. There is a site that searches your birthday in Pi (π). What that means is it will search for the string that represents your birthday. I searched for my son’s birthday 1612010 and the result I get is:
The string 16122010 occurs at position 25736698. This string occurs 2 times in the first 200M digits of Pi, counting from the first digit after the decimal point.

6. Albert Einstein, the famous scientist was born on Pi Day (14th March)
7. 3.14 backwards looks like PIE. That’s a good reason to eat a Pie on Pi Day 🙂
8. The digits in position 358 to 360 are 3,6 and 0 (360); that’s the number of degrees in a circle.
9. It is impossible to ‘square a circle’. What that means is that we cannot draw a square with the same area as a circle in finite number of steps.
10. Philish is a style of writing inspired by the number Pi (π). The length of words in a Philish sentence is determined by pi’s digits.
A Philish poem matching the first 31 digits of Pi (3.14159265 3589793238462643383279 ) was written by Joseph Shipley:
But a time I spent wandering in bloomy night; (3.14159265)
Yon tower, tinkling chimewise, loftily opportune. (358979)
Out, up, and together came sudden to Sunday rite, (323846264)
The one solemnly off to correct plenilune. (3383279)
