Classic Math Puzzle Cracked
An anonymous reader writes "This is cool - if mind-bending. A century ago, a self-taught math genius from India noticed some patterns in how numbers can be created by adding other numbers. Now a grad student has finished the job showing that the patterns apply to all prime numbers, not just some. There's more on the Indian math guy here."
you mean Srinivasa Ramanujan
Due to financial difficulties, the light at the end of the tunnel has been turned off.
More on Ramanujan at St. Andrews
Also at physorg.
It all deals with the Partition function.
That's got to be the worst write up I've ever seen on /.
This statement implies that the genius is famous because he noticed that there is/are pattern(s) in how you can add up numbers to get other numbers . . . that statement is so vague that the discovery could be incredible or intuitively obvious.
Quoted from one of the links is a much better explanation below:
One remarkable result of the Hardy-Ramanujan collaboration was a formula for the number p(n) of partitions of a number n. A partition of a positive integer n is just an expression for n as a sum of positive integers, regardless of order. Thus p(4) = 5 because 4 can be written as 1+1+1+1, 1+1+2, 2+2, 1+3, or 4. The problem of finding p(n) was studied by Euler, who found a formula for the generating function of p(n) (that is, for the infinite series whose nth term is p(n)xn). While this allows one to calculate p(n) recursively, it doesn't lead to an explicit formula. Hardy and Ramanujan came up with such a formula (though they only proved it works asymptotically; Rademacher proved it gives the exact value of p(n)).
9^3 + 10^3 = 729 + 1000 = 1729
The coolest reference on Hardy's reaction to Ramanujan's initial letter is seen in a letter that was sent by Bertrand Russell to an acquaintance. It goes something like:
"Saw Littlewood and Hardy in a considerable state of excitement. They claim to have discovered a second Newton, a Hindu clerk working in Madras for 20 pounds a year...It's all secret now, of course. I feel excited to know this"

He didn't die from a "mystery illness", he died from tuberculosis (or as it was called back then, the consumption).

His name is in the first sentence.
I just moused over, and it's in the freaking URL.
Gauss did quite a lot of things in math, but inventing imaginary numbers was not one of them. These numbers were known long before him and their name was coined by Rene Descartes, as a quick glance at wikipedia would reveal. Incidentally, Descartes named the numbers imaginary exactly because he did not believe they could "exist."
Gauss was french
Gauss was one of the greatest german mathematicians, my friend.
