Sir Srinivasa Ramanujan invented a very interesting magic square. Take a look at it. If you add the numbers horizontally, vertically, or diagonally, you always get the same total, which is 139. That is why it is called a magic square. Now, what is truly magical about it? He created this square using his birth date. If you observe the starting numbers carefully, they represent 22 December 1887. This shows how deeply he used to think and analyze.
