your optimism disgusts me

Here is it: The worlds best measurement of the anomalous magnetic moment of the muon

In great agreement with previous experimental results and in agreement with the Standard Model prediction using the LO HVP contribution from lattice input

Update of the muon g-2 White Paper out at arxiv.org/pdf/2505.21476. Paradigm change:

- Lattice-based HVP determination now taken as consensus SM prediction.

- Conundrum in HVP determinations based on dispersion relation + e+e- data now apparent. Tau-based version in interesting bridging role.

Las golondrinas buscan desesperadas un hueco en la estúpida malla que les impide nidificar en el parking del DIA en Manzanares el Real (Madrid). Había decenas de nidos el año pasado.

Desde 2004 @seobirdlife.bsky.social estima que han desaparecido 10 millones de golondrinas en España.

As promised, here are the slides I shared with students to convince them to NOT use chatGPT and other artificial stupidity.

TL;DR? AI is evil, unsustainable and stupid, and I'd much rather they use their own brains, make their own mistakes, and actually learn something. 🪄

The Democrats on the House Science Committee have set up a website to collect stories from fired federal employees, anonymously if desired. Please amplify. (This helps the lawyers establish standing for bringing legal cases against the administration!)

All happening at once in Hamburg: pride day, a soccer match at a soccer stadium with pride flags & signs that say “United against racism”, a World War II bunker turned into a dance club, and several political parties, including the far right, handing out pamphlets and having demonstrations.
