Introduction
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.” – Antranig Basman, mathematician and software developer.
Did you know that the Nobel laureate Albert Einstein was born on 14th March? Or, that the noted physicist Stephen Hawkings died on 14th March? And, did you know that March 14 is a very special day for Math admirers?
Well, it is Pi Day!
Pi Day is celebrated on March 14 to commemorate the significance of the mathematical constant π (pi). It is observed on March 14 (3/14 in the month/day format) because 3, 1, and 4 are the first three significant digits of π.
The exact time of the celebration is at 1:59 pm, considering the date (3/14) and time (1.59), it forms 3.14159, the approximate numerical value of pi.
From Archimedes's time, mathematicians have been trying to find the value of pi, each subsequent time leading to a more efficient and better result. Till the 17th century, only 38 digits of pi were known.
In the 18th century, a mathematician, Johann Heinrich Lambert proved that pi is irrational. With modern technology at our disposal, we now know pi up to 31 trillion digits but only 39 digits or so are needed to calculate anything in our universe without error.
If you want to understand what Pi is, then take any circle. Then divide its circumference by its diameter. You will get a number. Now take a different circle and divide its circumference by its diameter.
To your surprise, you’ll get the same number as before. This number is Pi – a naturally occurring mathematical constant.
Pi Day was first organized on March 14th, 1988 at the San Francisco Exploratorium by the American physicist, curator, and artist Larry Shaw.
He led his enthusiastic staff to march around one of the circular spaces at The Exploratorium and then they ate fruit pies.
This is because the words “pi” and “pie” are homophones (words having the same pronunciation but different meanings and spelling) in English. Coincidentally, a pie is also round in shape; hence related to Pi.

Do you know why Pi Day is celebrated? |
How Do Math enthusiasts Enjoy Pi Day?
- Enthusiasts pi-ans also celebrate Pi Day by reciting the infinite digits of Pi and discussing the significance of the number π.
- Foodies relish Pi Day through pie-eating contests, pie fights, and pie baking contests.
- Pi Day can also be a great excuse to cheat your diet and eat a Pizza.
Pi Is All Around Us!
- Even the rivers bend to the tune of Pi! Their sinuosity or the average “meandering ratio” (the ratio of the river’s actual length divided by the straight-line distance from its source to its mouth) approaches Pi.
- Ever wondered about the stripes of a zebra or the spots of a leopard? The code behind those unique sizes and spacings is once again – Pi !!
- Egyptians believed that the architectural extravaganza, the pyramids of Giza were built on the core principles of Pi.
- The altitude of the pyramids has the same relationship with the perimeter of their base as it is in the case of a circle’s radius and its circumference.
“Exploring pi is like exploring the universe.” – David Chudnovsky
What to do on Pi-day?
Cuemath cherishes this enigmatic number and wishes you all, a very happy Pi Day!
We commemorate the contribution of two geniuses who have redefined time and space – Albert Einstein and Stephen Hawking on this important Mathematical day.
Celebrate this holy math day and share the Pi Day spirit with your family and friends. For starters, you can do the following with kids:
- Recite the decimals of Pi with kids.
- Order a pizza (or homemade for health enthusiasts) and explain that Pi is the ratio of circumference to the diameter using a scale. You can explain that Pi is infinite and no one can measure this ratio perfectly.
- Solve the following puzzle with your kid: If the circumference of the circle is 50 cm, find the length of each side of the square.
How to Celebrate?
- Pi is a homophone of pie - the 2 words are pronounced similarly but are spelled differently and mean different things. Celebrate Pi Day by having lots and lots of pie.
- Have a pie baking contest. Ask participants to bake pi shaped pies. Combine it with a pie-eating competition.
- Have a pi recitation contest. Anyone who can recite the most digits of the constant gets to take home a pie.
- Embrace your geekiness. Wear a t-shirt that has the numbers of pi on it or sport some pi shaped accessories. Earrings perhaps?
- Eat foods that start with a pi, like pineapples and pizza, or foods that are circular in shape, like pancakes and cookies.
- Watch the 1998 Darren Aronofsky movie, Pi.
The infinite life of pi - Reynaldo Lopes
Conclusion
This blog mainly talks about pie day Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern.
