Okay, so when I first began trying to figure out what to do with my last blog post I was clueless. I almost felt like I had too many options. So, I began working my way down Professor Golden's list of "Weekly Options" one by one, honestly skipping a few in between. None of the options were catching my eye at first. But, then I made my way back up to the top of the list (one by one this time) and I came across the Youtube video of Ramanujan's Magic Square and 27 seconds in the mind blowing began!

When we worked with magic squares the rows and columns of every 3x3 and 4x4 square had equal sums. True enough I struggled at first, but after a while I got the hang of it.This in itself was enough to keep me interested. But in comes the Ramanujan's magic square! We thought we were mastering something with the first squares and all along we were amateurs (just kidding)! There are so many interesting sums in this magic square, it's best I list them. Lets start with the "common" things (I'll refer to the lettered diagram pictured using the letters as labels only... the numbers would be that of the Ramanujan magic square on the right):

1. The sum of the numbers of any row is 139

2. The sum of the numbers of any column is 139

3. The sum of the numbers of any diagonal is 139

And then comes the good stuff!!!

4. The sum of the numbers of the corners is 139

*** i.e. a+d+m+p = 139

5. e+i+h+l = 139, b+c+n+o = 139, c+h+i+n = 139, b+e+i+o = 139

6. The sum of any central square is 139, in other words any 2x2 square inside of the 4x4 square has a sum of 139 (yeah, I was confused too)!

7. Srinivasa Ramanujan was born on the 22nd of December in 1887... wait for it, wait for it... (Go back and check out the top row of Ramanujan's magic square)!

BOOM!!!
