Celebrate Pi Day with Interesting Facts and Brief History

The mathematical constant Pi is represented by the Greek letter ‘π’, which is used by mathematicians all around the world. Since then this Pi symbol has been used all over the world.

Mathematicians are fascinated by this irrational number that determines the areas of circles. Larry Shaw, a scientist, designated 14^th March as 'Pi Day' in 1988, based on Pi's value of 3.14. He organized the event to bring the math community at the Exploratorium Science Museum in San Francisco together. Today, Pi Day March 14^th is observed all across the world.

In our life, the only two constants are change and Pi. It's worth noting that Pi is essential for comprehending and calculating how alternating current travels and waves generate. It affects every aspect of our lives, including automobile engines, construction materials, skyscrapers and bridges, farming silos, meteorology, motors, space science, and power generation.

History of Pi Day, March 14^th

As mentioned earlier, in 1988, a scientist named Larry Shaw designated 14^th March as the celebration of Pi day. Since then, Pi day is celebrated on 14^th March every year.

The United States House of Representatives passed a non-binding resolution on March 12, 2009, declaring March 14, 2009, to be National Pi Day. Google presented a Google Doodle for Pi Day 2010 and the 30th anniversary in 2018, it was a Dominique Ansel pie with the circumference divided by its diameter.

Some people declared the month of March 2014 (3/14) to be "Pi Month." The 14^th of March was designated as "Super Pi Day" in 2015. Because the date is written as 3/14/15 in month/ day/ year format, it has unique importance. The date and time combined at 9:26:53 reflected the first 10 digits of Pi value, while the second Pi Instant later represented all π's digits.

Interesting Facts Related to Pi Value & Symbol

Here are some of the interesting and unknown facts related to the Pi symbol, value, and date. Read these facts and fill your knowledge bag:

1. Apart from 14^th March, there are alternative dates when Pi day is being celebrated:

• Since the fraction 22/7 is a frequent approximation of π, which is accurate to two decimal places and dates from Archimedes, Pi Approximation Day is celebrated on July 22 (22/7 in the day/month format).

• On June 28 (6/28 in the month/day format), Two Pi Day, also known as Tau Day, is honoured in celebration of the mathematical constant Tau, which is calculated as 6.28.
• The 10^th of November is also known as Pi Approximation Day because it is the 314^th day of the year.

2. Pi is also known as Archimedes Constant, Circular Constant, Ludolph’s Number.

3. There is no special reason or theory behind the Pi symbol. However, the pi symbol is the 16^th letter of the ancient Greek alphabet.

4. On this day in 1879, one of the great scientists, Albert Einstein was born.

5. Pi value is also used by NASA to calculate the size of craters, find exoplanets, learn about the composition of asteroids, and calculate the amount of propellant a spaceship carries.

6. Do you know there's a planet named Pi? It's K2-315b, an exoplanet whose orbital period is equal to the value of pi. This planet revolves around its star every 3.14 Earth days. It is about the same size as Earth, having a radius that is 95 percent that of our own planet. That's about the same size as Venus, and it's a scorching hot environment, with temperatures reaching 350 degrees Fahrenheit, just like our neighbouring sister world (177 degrees C). EPIC 249631677, a red dwarf (or M dwarf) star 186 light-years from Earth, is cooler than our sun and only about 1/5 the size of our sun.

So, these are some of the unknown and interesting facts about Pi's value, symbol, and day on which it is celebrated. Hope this excites you and increases your knowledge about Pi day.
