Something extraordinary

The Belcea Quartet were playing in Cambridge again a couple of days ago, in the wonderfully intimate setting of the Peterhouse Theatre. They are devoting themselves completely to Beethoven for a couple of years, playing all-Beethoven concerts, presumably working up … Continue reading

KGFM 20, 21: Woodin on the transfinite, Wigderson on P vs NP

And so, finally, to the last two papers in KGFM. I can be brief, though the papers aren’t. The first is Hugh Woodin’s ‘The Transfinite Universe’. This inevitably mentions Gödel’s constructible universe L a few times, but otherwise the connection … Continue reading
