A hopeful silver lining is that the mathematics community will make the long overdue move to more highly rewarding communication and exposition

The dreamteam is Polgar and Leko together, both so much respect for the game, Polgar's wild tactical imagination and Leko's feeling for positional nuance

Watching Judit commentate lately is such a treat. She has such total board tactical vision, reminds me of Kasparov

No, but it would be surprising for people at major universities to need cosy up to someone like Epstein to get the money they needed for their research

I’ve seen a list of about a dozen fairly prominent academics who seemed to have quite a bit of contact with Epstein

Don't think Dershowitz and co are in the Epstein files because they weren't making enough money

Do you discuss notions of representation found in mathematics? E.g. group representation, representable functor

Omfg, all my adult life I've believed that the discovery of what went wrong was solely due to one showy physicist. And that's what showy physicist dot com would still have you believe

He's saying that Europe and the US need each other. If you're saying that only one half of that will be heard by Trump and be damaging, then maybe. Perhaps "We are stronger together" would have been better. Agreed that it is bizarre to say that Europe cannot defend itself; against whom, aliens?

Having gone through the comments to the question, wasn't the original question meant to be along the lines of: "What does it mean for a proof to pick a basis?" ?

At 9 seconds he says "we need each other", and the rest is an elaboration on that, specifically with reference to Arctic security, where everyone knows that US capabilities are dismal

I don't follow. His main assertion is that Europe and the US need each other, as evidenced by the US's dismal arctic abilities. Sounds like his principal target is go-it-alone types on both sides of the Atlantic?

But who's the audience? Rutte is one of the chief designated Trump whisperers, so interpreting his comments always has to take that into account. Couldn't he just be in the business of buying more time?
