Pi Day is celebrated every year on March 14th. This day was formed to celebrate the mathematical constant π. It basically falls on 3/14 as three, one and four are the first three digits of PI. Pi day is a holiday that has been observed all around the world since the year 1988 and has been celebrated by millions of math students and teachers around the globe since then.

**Interesting Facts about Pi**

**Pi is all encircling**

In the endless stream of Pi digits, it is believed to comprise the numbers 0 through 9 in each possible amalgamation, forming every possible series of digits.

As per the Patrick Ingram, a mathematician at York University in Toronto said, “This hasn’t been proven — but in theory, if you choose some string of a million digits, it’s in there somewhere — and then it’s in there again, infinitely often”.

**Pi is prehistoric**

However it wasn’t called pi up to the 18th century, the arithmetical connection in the middle of a circle’s diameter and circumference has been considered since ancient times.

Also, in the second millennium B.C., the Babylonians used 25/8 for pi (equal to 3.125), despite the fact that the Egyptians are supposed to have used 256/81 (equal to 3.160).

**Only a bit is required more than a dozen decimal places**

However pi includes trillions of digits but we don’t really need them. Even, the engineers at NASA round pi off to 15 decimal places when computing space courses.

**Computers calculated pi to more than 22 trillion digits**

In the year 2016, a Swiss scientist, Peter Trueb, used a computer with 24 hard drives and a program named as y-cruncher in order to evaluate pi to more than 22 trillion digits, the present world record for the listing of pi. If you read one digit each second, it would take you just under 700,000 years in order to count all those digits.

**There are plenty of additional reasons to celebrate March 14**

Other than marking Pi Day on March 14, there are other reasons too in order to celebrate March 14 such as Albert Einstein’s birthday. Also, physicist Stephen Hawking who is considered by some to be Einstein’s scholarly successor also died on March 14, 2018.

**Quotes on Pi Day 2019**

Here are some quotes on pi, let’s have a look:

“Pi is not just a collection of random digits. pi is a journey; an experience; unless you try to see the natural poetry that exists in pi, you will find it very difficult to learn.”

“If equations are trains threading the landscape of numbers, then no train stops at pi.”

“Pi occupies a key place in trigonometry too. It is intimately related toe, and to imaginary numbers. Pi even shows up in the mathematics of probability.”

“Pi is not merely the ubiquitous factor in high school geometry problems; it is stitched across the whole tapestry of mathematics, not just geometry’s little corner of it.”

“It’s exact and indefinite. It’s like pi- you can keep figuring it out and always be right and never be done.”

“Pi world’s is so amazing, overall because we are looking for something that even we don’t know exactly what it is.”
