Liebe @zeit.de! Euer Artikel "Oh, Geheimnis" vom 25.7. beginnt mit
"Beinahe jeder Wissenschaftler erlebt irgendwann einmal den Augenblick des Triumphes über seine Widersacher und Konkurrenten..."
Das ist glücklicherweise großer Quatsch. Normalerweise haben Wissenschaftler:innen keine Widersacher.

Paper Alert:
My first joint paper with Christian Krattenthaler:
Positive m-divisible non-crossing partitions and their Kreweras maps
The project took forever. Started in 2012. Has 169 pages.
I love the results, but the proofs are the most technical treatment I ever did.

I just love vibe coding! It is such a game changer.
Comment 1 (screenshot): It is so funny when I explain sth and copilot implements parts and forgets the rest. I then remind it to complete my request, and it admits to have forgotten to finish the work. Copilot really behaves human-like.

Part 2:
How many integers are there? Infinitely many.
How many even numbers are there? Infinitely many.
And infinity = infinity.

Top! Postkartenformat o.ä. Hauptsache easy, günstig, schnell druckbar. Keine Partei-werbung, schlicht.
Idee ist, sie mit den Flyern zu verteilen. 75% der Flyer gehen an nicht-AfD-Sympatisant:innen. Wir wollen auch diese dazu bewegen sich einzubringen. Z.B. darüber mit Ihren Nachbar:innen zu reden.

I find it very hard to write about math these days. Anyways: I proudly present
Cataland: Why the Fuß?, Memoirs AMS.
arXiv 2015, accepted 2020, published 2025.
One reason for the delay being the complicated typesetting, open the book to find out why. (I haven't yet seen it either.)

I recently came across the following announcement in which the the circle was squared. I am happy to share that
π = 3844/1225.
The details do not matter too much, I think. And why should I check facts anyways.

The exterior angle thm tells you that alpha > beta, but both are right angles.
(I am not sure you are allowed to use this thm at your stage of the argument, though.)
