Today I started to read the Ramanujan biography ( The e-book version, of course. ) The book looks promising. What was it like to communicate with someone gifted with such powerful mathematical insights? I am hoping ( a bit less after every failed try ) for a book that pulls me in that world of it's own. I have been there before on many occassions, while reading other books of course. Scientologists have a special word for it: exteriorizing.

At a very young age he designed the following formula for a 3 by 3 magic square:

C+Q | A+P | B+R

A+R | B+Q | C+P

B+P | C+R | A+Q

where A,B,C are integers in arithmetic progression and so are P,Q,R.

Try it, it works!

dis is wonderful...dis is in real sense...a magic...by a legend...

ReplyDeleteHad the numbers not in A.P.,we can get sum of all the columns and rows to be same.By taking numbers in A.P.,he gave us a real magic square in which even the sum of diagonals is also same.It shows in how much depth great Ramanujan was into the subject.He is an inspiration.

ReplyDeleteWow , really a great magical formula. I love to use this formula again and again.

ReplyDeleteThanks for posting great article.
