For decades, mathematicians have debated a simple question about graphs and the number of connections they have. Now using arguments an undergraduate math student could have come up with, Asaf Ferber of the University of California, Irvine and Michael Krivelevich of Tel Aviv University have finally provided the answer in the form of a proof posted in March.

After more than 70 years of intransigence, one of the most stubborn numbers in math has finally budged. In a four-page proof posted in late September, Asaf Ferber, of the University of California, Irvine and David Conlon, of the California Institute of Technology provided the most precise estimate yet for "multicolor Ramsey numbers," which measure how large graphs can become before they inevitably exhibit certain kinds of patterns.
