## What is so special about Srinivasa Ramanujan's Magic Square?

You may be familiar with magic squares. Srinivasa Ramanujan also designed his own magic square.

This magic square looks similar to any other square. What is so special about it?

Sum of any rows is 139

Sum of numbers of any column is also 139. Does it make a special square?

Sum of any diagonal numbers is 139.

But this is pretty common in other magic squares! Wait...

Sum of corner numbers is also 139.

Sounds interesting!

Sum of same coloured boxes is also 139.  Really!

Look at other possible combinations like sum of identical colour boxes is 139.

Wow!

Sum the central squares... 139 Simply Great!

You may try other combinations... isn't it superb?

Do you know the relation between the square's first row and Ramanujam?

It is 22.12.1887 - Ramanujam's Birth Date (December 22, 1887)

By the way 139 is a prime number.

There is a movie with a title 'The Man who knew Infinity', showing life experiences about him. There is a good book with the same title 'The Man Who Knew Infinity: A life of Genius Ramanujam' by Robert Kanigel (Available at Amazon also).
