A century-plus old math problem, once believed to be unsolvable finally has a solution. The hand written solution would cover some twenty square miles (51.8 km²), or the entire island of Manhattan. This problem known as "Lie group E8" (pronounced Lee), and others, were invented by a Norwegian in 1887. The puzzle spans 248 dimensions, what that means, I don't really know, other than it is more that the three that we can easily understand.

The solution, stored on a computer, takes up 60GB, or 45 days straight of MP3 tracks!
