Blog Post #152: Another small tribute to Srinivasa Ramanujan



As we step into a New Year, I wanted to take a moment to share a small tribute to the great mathematics genius, Srinivasa Ramanujan, whose 138th birth anniversary we celebrated on December 22nd. Although I am a few days behind in penning this post, the inspiration Ramanujan continues to bestow upon me remains timeless.

 

Ramanujan's profound contributions to the world of mathematics continue to be a guiding light for many, including myself. His unique ability to perceive numbers and patterns through an unconventional lens always fascinated me. Each time I delve into the world of mathematics and numbers, I find myself marveling at the seemingly infinite possibilities and the elegance of Ramanujan's insights.

 

His legacy encourages us to approach problems with a different perspective by breaking those down into smaller chunks, that could be solved to arrive at the big picture

 

I have made an attempt to look at some interesting patterns around Ramanujan's birth anniversary. Here we go!

 

a) 22-12-2025 was his birth anniversary - If we add the digits the resultant is 16 which is a perfect square of 4 which in turn is a perfect square of 2

 

b) Now add the "squares" of each digit of Ramanujan's birth anniversary - 2 ^ 2 + 2 ^ 2 + 1 ^ 2 + 2 ^ 2+ 2 ^ 2 + 0 ^ 2 + 2 ^ 2 + 5 ^ 2 and the output is 46. At first glance it looks like any other two digit even number but here's why it is unique - 2025 is the only perfect square of this century and the next perfect square year is 2116. Guess what - Square root of 2116 turns out to be 46!

 

c) Let's group the birth date into two 4 digit numbers - 2212 and 2025. Now subtract 2212 and 2025 which results in 187. 187 is a multiple of 17 and 11. When we draw a parallel to Ramanujan's birth year - 1887, it shows a very similar pattern - 1887 is a multiple of 17 and 111!

 

d) There is always a connection between Ramanujan number (1729) and the entire universe and this blog post is no exception - Here's why!

 

2025 is a perfect square year as we know by now and the next perfect square year is 2116. The difference between the two of them is 91 and when 91 is multiplied by its reverse (19) the output is none other than Ramanujan number - 1729!! It does not stop there... The previous perfect square year was 1936 (44 ^ 2) and difference between 2025 and 1936 is 89. 89 ^ 2 is 7921 and guess what - Anagram of 7921 is 1729 again :)

 

Numbers and patterns continue to amaze us and glad that i could contribute towards that in a small way on the occasion of Ramanujan's 138th birth anniversary - "The Man who Knew Infinity" continues to inspire me and many others!

 

Wishing everyone a very Happy, Healthy and Prosperous New Year!
