#Physicists think they’ve solved the #muon mystery
Results dash hopes for a fifth force but provide very precise proof of the #StandardModel of #particlephysics and quantum field theory. According to a paper published in the journal Nature, the discrepancy is due to a calculation fluke, not exciting new #physics, so the Standard Model of particle physics is still holding strong.

#Muon g-2 Experiment Pioneers Win #BreakthroughPrize in Fundamental #Physics | CERN
https://home.cern/news/press-release/cern/muon-g-2-experiment-pioneers-win-breakthrough-prize-fundamental-physicsCongratulations! This is one of the most difficult measurements that can be undertaken.

i have added a #muon build to #pkgconf CI. the goal of this is to allow us to begin thinking about deprecating the autotools-based build system.
this won't happen until next year, most likely, but muon is sufficiently complete at this point that i think it solves the bootstrapping problem enough that we can start thinking about getting rid of the autotools stuff, probably in pkgconf 3.1 or so.

Students at #SNOLAB are starting to engage in our common orientation for research experiences. One particle that comes up really early is the #muon. Students often don't learn about subatomic particle properties other than #electrons, #protons, and #neutrons until late in university. I made this video explicitly to help early-career students get familiar with the muon and see how it was the first direct test of the #relativity of time:

#KnowledgeBit: The #Muon is one of the fundamental subatomic particles, the most basic building blocks of the universe as described in the Standard Model of particle physics.
Muons are similar to electrons but weigh more than 207 times as much. The muon is part of the lepton group.

"After measuring the wobbles of 300 billion muons, the Muon g − 2 Collaboration has pinpointed with exquisite precision the internal magnetism of these subatomic particles. [...] In a somewhat surprising turn of events, the final results from the Muon g − 2 experiment line up with the most recent predictions, further validating the standard model of particle physics."

#OnThisDay Birth Anniversary of Louis Sullivan (1856) - American architect, and has been called the "father of skyscrapers" and "father of modernism".

The magnetic moment of the muon revisited
A couple of years ago I posted an item about a measurement of the anomalous magnetic moment of the muon, a quantity usually known as (g-2). At the time this appeared to be in conflict with the predictions of the standard model (SM)of particle physics but the general opinion among experts was that the problem was likely to lie with the calculations rather than the experiment.
Well, catching up on things I missed during examination marking season, I refer you to a substantial paper (188 pages long) that appeared on arXiv on 27th May 2025, with the abstract:
If this is too small to read I direct yourself to the salient point, namely that “there is no tension between the SM and experiment at the current level of precision”.
It seems the Standard Model survives to fight another day…

And, let me not forget the #mystery of #gravity! Omnipresent, never seen...sound familiar?
"#spooky at a distance" gets much closer to #earth when #science spends billions on a huge shrine to the #particle gods (#LHC) and buries another deep underground hoping to come in direct contact with the god #muon (also known as #neutrino)

In the next printing of Sapiens its author may want to reconsider the claim that #relativity isn't a #religion. There are many #science #gods that #physics venerates as #animist #supernatural phenomena: #darkmatter, #darkenergy, #antimatter, #muon and #higgsboson #particles; a #blackhole, the #bigbang, #multiverse and #quantumphysics* are all effectively a #belief #system.
As someone once replied to me, dismissively: "I only believe in the Standard Model"
(*Note I said quantum "physics")

The muon g-2 puzzle rolls on.
"New, robust experimental measurements of the muon g-2’s dominant hadronic processes are also expected over the next couple of years. [...] It’s going to be an exciting few years. Being part of both the experiment and the theory means I have been privileged to see the process from both sides."

Huh, I know autotools is old and horrible but I didn't know there was anything to replace it.
This #muon thing sounds interesting.

#fvwm3 #autotools #meson #muon #buildsystem
Hey all! Please note that although fvwm3-1.1.1 is close to being relesaed, there's still a few more things left to do.
Before that point, I'd like to take the opportunity to mention that as of fvwm3-1.1.1 fvwm3 is officially using meson/muon as the buildsystem of choice.
Autotools has been a tremendous help over the years. Heck, fvwm as a project started long before autotools existed.
But as technology changes, newer buildsystem alternatives have come along making better use of hardware, compilation speeds, etc.
Indeed, because of fvwm's age -- there's a tonne of custom m4 macros -- some of which are to work around issues long since gone. With autotools recently deprecating many of these, maintaining this was becoming difficult. Hence the change.
A six-month window exists once fvwm3-1.1.1 is released for downstream packagers to make the move from autotools to meson.
The `main` branch in the fvwm3 repository contains both buildsystems. Please give meson some testing!
A huge thanks goes to Kanjie (Matt Jolly) -- without whom none of this work would have been possible. Thanks, Matt!
For more specific details. please see: https://github.com/fvwmorg/fvwm3/discussions/1068
