What You Probably Did Not Know About Pi (π) In Mathematics by Ebookmathswaec: 4:33pm On Dec 17, 2017 
Pi (π) is simply defined as the ratio of circumference of a circle to its diameter. That is: π = circumference/diameter = 3.1415926535… It is one of the constants we have in Mathematics. For the convenience of students, Pi (π) is taken to be ^{22}/_{7}. This is not exactly correct. It should be noted that Pi (π) is an irrational number. It cannot be expressed exactly as a fraction. Pi (π) = 3.14159265358979… with the digits going on and on with no specific pattern. The digits keep going on and on without ending. It is a crazy mathematical constant! Pi (π) with the first 100 decimal places is as follows: π = 3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679… On March 21 2015 , a 21yearold Indian student, Rajveer Meena set a Guinness World Record on Pi (π). He memorized 70,000 postdecimal digits of Pi. He made the record by reciting the π digits up to 70,000 digits. He did that in 9 hours 27 minutes. Rajveer wore a blindfold throughout the entire recall. Pi (π) Day Pi (π) Day is celebrated on March 14th around the world. Why March 14th? March 14 could be written as 3/14. The first three digits of Pi (π) is 3.14. Pi (π) Approximation Day Pi (π) Approximation Day is also celebrated on July 22 around the world. Why July 22? July 22 could be written as ^{22}/_{7} (day/month date format). ^{22}/_{7} is a common approximation of π especially for the convenience of students. More at: www.edmaths.com 3 Likes 2 Shares

70,000 digits. That's great!

More than 70,000 digits but still a constant. This goes to show that we really live in a geometry based reality. 1 Like

eTECTIVe:For me maths is more important than English. Maths is like a universal language. Anything represented in mathematical terms will be viable even in Pluto. Maths will enable the inquisitive mind study reality and even quantum mechanics. Have you heard of spatial maths? 2 Likes

eTECTIVe:The first example I remember. I can use it to determine the distance between 2 points on a spherical object if you give me the diameter of the circle and the longitude/latitude data of the points only. The sphere could be as big as Jupiter. This method when used can lead to easier calculation of stuff like flight path and time. 2 Likes
