The ultimate faculty recruitment list: Hermann Weyl recommending physicists and mathematicians for the IAS in 1945. The competition is so stiff that Eugene Wigner and Hans Bethe are considered second-tier.



Read too many good books recently so I’m gonna read Way of Kings to balance it out





It was a glorious morning for a picnic in Prospect Park with NY-10 neighbors! These families first met because they were outraged by Israel’s destruction of Gaza — and by Dan Goldman’s refusal to do anything to stop it. All our kids deserve to grow up safe & free.

Wow, the sum-product conjecture is also false over \R, via a construction analogous to that of Balog-Wooley in the setting of the below line of ideas, i.e. non-asymptotic-but-good-enough point counting results from the geometry of numbers that kick in over class field towers because the discriminants and regulators are then only exponential in the degree Two crazy-famous conjectures down. Everybody go try your constructions out in these fields! Congrats to Thomas, Will, Carl, and Dmitrii:D arxiv.org/abs/2605.28781


My god the new proof is an extremely clever application of algebraic number theory to a problem that at first doesn’t have anything to do with it. The AI generated version of the paper is also unusually readable
