Loeb lecture: John Preskill

John Preskill is a very interesting physicist, and he will become the next Loeb lecturer at Harvard next month.

At the faculty lunch seminar, Xi Yin was deriving OSV from M-theory, using the "AdS3 x S2 x CY3" near-horizon geometry (work with Andy Strominger and Davide Gaiotto) of M5-branes wrapped on some four-cycles of the three-fold. If I will time, I will describe it in some more detail.
