Google sets

Imagine that you know a few elements of a set and you want to find the remaining elements. Impossible?

Google sets helps you

For example, try January & February to get the remaining ten items. ;-) Or try Leden & Duben to get the Czech names of the months.

Or enter Edward Witten & David Gross to the first two windows and you get a pretty decent list. Or try Quantum Field Theory & General Relativity. You get various other concepts including their unification. Or Cosmic Variance & Musings.

Try Type I & Type IIA. Among a few low-brow entries, you also get heterotic E8 x E8 and heterotic SO(32) string theories (in Japanese). ;-)

The difference from Alexander Wissner-Gross' Wikiosity is that you may enter several items.
