Quantum superposition and spinors – a saga of electrons

[What’s changed in the last ~100 years] A recent Scientific American article reminded me that quantum spin underlies the stability of matter – without which there’d be no life. But the article prompted another dive into the “mathematical machinery” describing the quantum state of a single electron or a single photon. The Stern–Gerlach experiment established… Continue reading Quantum superposition and spinors – a saga of electrons

Evidence for new physics? > Fermilab’s Muon g-2 results announced

As noted in comments for my “The future of (particle) physics?” post, the first results from Fermilab’s Muon g-2 experiment are a big deal for physics. Waiting for years. Highly anticipated. As expected, today these results were officially released. Fermilab itself released an excellent YouTube video visualization which includes background on the project and experiment… Continue reading Evidence for new physics? > Fermilab’s Muon g-2 results announced

Quantum spin — angular what?

I’ve been reading about quantum spin for awhile and taking notes. Hobson’s book1, for example, discusses the foundational experiment which discovered spin. In the mean time, Space.com posted an article today which may serve as a placeholder for the topic while my draft notes on other topics develop. The Space.com article “The Weird Quantum Property… Continue reading Quantum spin — angular what?
