One of the things it's hard to appreciate from a modern viewpoint is how alien the idea of parity violation was at the time. I tried to capture some of the resistance to the idea here, and the brilliance of Lee, Yang, and Wu to capitalize on it.
Physics History October 1956
Until the pair’s explosive paper, physicists assumed that particles would act the same when mirrored.

Experimental Observation of a Heavy Particle $J$
We report the observation of a heavy particle $J$, with mass $m=3.1$ GeV and width approximately zero. The observation was made from the reaction $p+\mathrm{Be}\ensuremath{\rightarrow}{e}^{+}+{e}^{\en...

Congratulations @willpietrak.bsky.social for your new adventure! It was a pleasure working with you. Good luck!
After 8 incredible years as part of the LHCb collaboration at CERN, it is time for me to explore new horizons. I am very happy to announce that I am now a contractor for SII, working as a software developer for clients in the parisian area.

Attending the excellent seminar of Josh Bendavid on the W mass at CMS at Milano Bicocca today reminded me of the difficulties of properly aligning a particle detector 😅
