# It’s Pi Day!

**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 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 lovers?

Well, it is Pi Day today!

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 celebration is at 1.50pm, considering the date (3/14) and time (1.59), it forms 3.14159, the approximate numerical value of pi.

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 another 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 organised 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 consumed 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 pie is also round in shape; hence related to Pi.

**HOW DO MATH LOVERS 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

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 the Math lover in you 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.*

- Live one on one classroom and doubt clearing
- Practice worksheets in and after class for conceptual clarity
- Personalized curriculum to keep up with school
