# Yes, it’s Pi Day

Yes, it’s Pi Day

Pi Day is celebrated on 14th March, every year by math lovers and mathematicians all over the world. It is celebrated specifically on March 14th because the approximate value of Pi is 3.14, the ratio of a circle’s circumference to its diameter. Pi’s first calculation was done by Archimedes of Syracuse (287-212), an ancient Greek mathematician and astronomer. He also calculated the area of a circle with the use of the Pythagorean Theorem.

Pi has been used in different cultures for a long time. Such as:

• Egyptians:The ancient Babylonians and Egyptians used approximations for pi when calculating the area of a circle.
• Chinese: Zu Chongzi (429-501), a Chinese mathematician, just like Archimedes created a radio that approximated pi.
• French: George-Louis Leclerc (1707-1788), a French mathematician, showed that pi could be calculated with probability.
• Pi has been very important since its discovery. It is used almost everywhere. Radio, television, construction, GPS, telephones, power generations, motor, etc. all of this is possible only because of pi. Some Historians even argue about the ancient Pyramids of Giza, one of the Seven Wonders of the World, being constructed with the help of Pi as its structures are geometrical.
Some of the important facts about pi are:

• Pi’s symbol has been used for over 250 years.
• Rajveer Meena at VIT University, India has been recorded for reciting the most number of decimal places of Pi. He recited 70,000 decimal places.
• It is surprising to know that the true value of Pi can never be found as it is an irrational number.
• The exact time for Pi day celebration is on 14th March at 1:59 pm exactly so that it can match its approximation value 3.14159.
• There is an entirely new language made on Pi. Mike Keith wrote a book named ‘Not a Wake’ in this language.
• It can be said that many genius minds have a relation with pi because Albert Einstein was born and Stephen Hawking died on Pi day.

Pi is such a mysterious and amazing number that many people compete to find the most number of its digits. Apart from that, it is also used in movies and games. Mathematicians and maths lovers are literally obsessed with the number and try to go in great depths of the number.
