Revolut°Permanente « Pas de labo, pas d'hosto » : 168 agents des labos du CHU de Bordeaux en grève pour leurs primes: Depuis lundi, les labos du CHU de Bordeaux sont en grève pour réclamer la prime de participation aux bénéfices, refusée malgré des recettes record. Un ras-le-bol qui s'exprime face à des conditions de travail intenables et au plan d'austérité du gouvernement.Notre Classe / Bordeaux / Secundaria2 / Santé /… https://www.revolutionpermanente.fr/Pas-de-labo-pas-d-hosto-168-agents-des-labos-du-CHU-de-Bordeaux-en-greve-pour-leurs-primes?utm_source=dlvr.it&utm_medium=mastodon RP #Grève #CHU #Bordeaux #Primes #Santé

I love seeing primary(ish) sources for mathematical ideas.

Gauss wrote a letter to astronomer Encke dated Decemer 24th 1849, in which he first presents an integral form of a prime counting function. He states this is based on work he started in 1792 or 1793.

The famous "1/log" density of primes.
