Ramanujan’s Magic Square | by Tarun Kumar

One of the greatest mathematicians of India, Ramanujan’s contribution to the theory of numbers has been profound. He was indeed a mathematical phenomenon of the twentieth century. Ramanujan lived just for 32 years but during this short span he produced such theorems and formulae which even today remain unfathomable in the present age of super computers. He left behind him about 4000 formulae and theorems and one of them is Ramanujan’s Square. So have a look at it:

This seems like any other magic square. So what’s so great in this?

Sum of numbers of any row is 139.

So what’s so great in this?

Sum of numbers of any column is also 139.

But this will be there in any magic square.

What’s so great in this?

Sum of numbers in any diagonal is also 139.

Oh, But this will be in any magic square.

What’s so great in this?

Sum of corner numbers is also 139.

Interesting!

Now look at all the possibilities.

Sum of identical coloured boxes is also 139.

Interesting!

Look at these possibilities.

Sum of identical coloured boxes is also 139.

Nice !

Look at these central squares

Interesting ;)

Can you try these combinations?

Try these too....

Yes, it is 22.12.1887!

Hope you liked it!
