Google sets helps youFor 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.
