Every year, on July 22nd, mathematicians and enthusiasts around the world come together to celebrate Pi Approximation Day. This special day honours the number π (pi) and its fascinating properties, with the fraction 22/7 serving as a notable approximation. This year, I delved deeper into the history and significance of this mathematical marvel, reflecting on its journey and the impact it has had on our understanding of the universe.
A Brief History of Pi
Pi, the ratio of a circle’s circumference to its diameter, is one of the most celebrated constants in mathematics. The symbol π was first introduced by Welsh mathematician William Jones in 1706. However, the pursuit of pi’s value stretches back thousands of years. Ancient civilizations made their own approximations: the Babylonians estimated it as 3.125, while the Egyptians arrived at 3.1605. The Greeks, particularly Archimedes, refined these estimates to between 3.1408 and 3.1429 using geometric methods.
Aryabhatta and the Legacy of Pi
The Indian mathematician-astronomer Aryabhatta (476-550 CE) made groundbreaking contributions to pi’s approximation. His work in ancient India laid a foundation for future mathematicians, with Aryabhatta approximating pi as 3.1416—a remarkably close estimate. His insights into pi’s irrational nature, though not formally proven until later, underscore the rich mathematical heritage of ancient India and highlight the global quest to understand this enigmatic number.
The Magic of 22/7
Pi Approximation Day falls on July 22nd, celebrating the fraction 22/7, a common and close approximation of pi. While not exact, 22/7 provides a practical estimate for various calculations, reflecting the human drive to find simplicity and order in the complexities of mathematics. This fraction’s elegance and utility make it a cherished tool in the history of mathematical computation.
My Pi Approximation Day – A Touch of Nostalgia
Reflecting on Pi Approximation Day brings me back to my roots. At Raisina Bengali School in New Delhi, where my love for mathematics deepened, and as the school celebrates its centenary year, I’m reminded of my math teacher, Shyamal Krishna Roy Choudhury. His simple yet profound explanation of pi sparked my lifelong fascination with this number.
My time at Hans Raj College, University of Delhi, further deepened my appreciation for mathematics. The quest to understand pi was a constant companion during those years, symbolizing the pursuit of knowledge and the beauty of mathematical exploration.
The Significance of Pi in Modern Times
Today, pi transcends mathematics, embodying the limitless potential of human curiosity and ingenuity. Its applications span engineering, physics, computer science, and cosmology. Modern computing has enabled us to calculate pi to trillions of digits, yet its true nature remains an enigma, highlighting the infinite complexities of the universe.
Reflections and Conclusion
Pi Approximation Day is more than a celebration of mathematics; it’s a reflection on the boundless quest for understanding and the mysteries that drive us. As I gazed at the stars, each a symbol of pi’s infinite digits, I realized that the true beauty of pi lies in its eternal mystery—a mystery that continues to inspire and captivate us.
Happy Pi Approximation Day!
You still maintain your love for mathematics! Now I understand why did you choose Number Theory, while we opted for OR.

Absolutely! Mathematics has always been a passion for me, so I gravitated towards Number Theory. It’s fascinating how numbers can unravel so many patterns and secrets. Operations Research (OR) is also a great field with its own unique challenges and applications. An interesting incident occurred when I was asked to explain zero during my interview for the selection of Probationary Officers, and they didn’t know that Number Theory was my favourite topic. As I was delving into the details, they stopped me and asked another question. Thanks for reminding me; I’ll blog about this experience later.

What a small world!!!!
Shyamal Sir was my maths tutor.
He had such in-depth knowledge and love for math.
I was a very bad student though.
I am glad to know you are from Delhi. More so from Raisina. I am from Lady Irwin.
In our times these schools were renowned for their excellent teachers and outstanding students.

Indeed, it is a small world! Shyamal Sir was an exceptional mathematics teacher, known for his deep understanding and passion for the subject. I am proud to be taught by him and I used to be one of his favourites. It’s wonderful to connect with someone who shares a similar educational background.
Lady Irwin and Raisina Bengali Senior Secondary School were indeed among the top schools in Delhi during our times, renowned for their excellent faculty and remarkable students. It’s great to reminisce about those days and appreciate the quality of education we received.
