093 – The Standard Model of Particle Physics
This is the first episode in a series of episodes on particle physics and related research at CERN. In this episode we are talking to John Ellis about the standard model of particle physics, which is the current “big picture” about how subatomic matter and fields work.
- John Ellis
- King’s College London
- Standard Model
- James Clerk Maxwell
- Pauli Exclusion Principle
- Isidor Isaac Rabi
- Andrei Sakharov
- Cabibbo–Kobayashi–Maskawa matrix
- Asymptotic Freedom
- Unified Field Theory
- Fine-structure constant
- String theory
- Higgs Field
- Dark Matter
- Perturbation Theory
- Quantum Chromodynamics
- Quantum Electrodynamics
Quite a lot to understand, but did I overhear or did John not answer whether Spin means that particles are actually spinning?
Yes, this one is a bit heavier than the “wow, cool aiplane”-style episodes :-)
As far as I remember he said that Spin is not intended to be interpreted literally. No turning and spinning going on there.
Great interview, but I was thinking the same: I really wanted to learn what is meant by the ‘spin’ of a fundamental particle’. Clearly it isn’t a physical spin, but exactly what does it represent. Anyway, thank you Markus. I’ve wondered about the Fine Structure Constant for years and this helps a little!
Here is what Wikipedia says:
Does this help :-) ?
Puh! Rauchwölkchen entsteigen meinem Eiweißcomputer…
Wieder eine tolle Folge mit einem super Gesprächspartner, der dies an für sich “unverständliche” oder besser “unanschauliche” Thema m.E. so gut es geht dem geneigten Hörer nahe bringen konnte.
Ich muss es mir einfach noch Mal in Ruhe anhören, für nebenher beim Auto fahren ist es doch etwas zu hirnverknotend…
Ich freue mich schon – wie wir Schwaben sagen: “saumäßig” – auf die weiteren Folgen!
i’m so happy, that you’re doing this series on theoretical physics issues, thanks :)
btw, this short video on the higgs-boson might also be interesting
Another excellent podcast. Thanks for being a source of informative and interesting listening.

Compact but clear – a very helpful tour of the position at the point of recording. Recent reports of a ‘Higgs like’ particle at 5 sigma suggest that an update will soon be needed.
I might do an update, but not any time soon.

A great episode and I look forward to the others. I’ve listened #93 two times and understand even more. Thanks for Omega Tau.
I would like to suggest a youtube link: http://www.youtube.com/watch?v=IhSP08KOtl8 String theory is simplified now.
Great episode! Thanks a lot to John Ellis.

Have a fantastic journey. -Roger.
Very informative, interesting and accessible to a non-physicist. Well done. Recommended to me by a co-learner on an online course run by futurelearn.com
very good discussion really enjoyed listing to it, it is very informative
