I'm trying to think of real-world applications of the standard model of particle physics, but can't come up with anything.(adsbygoogle = window.adsbygoogle || []).push({});

Are there any technological applications in which neither non-relativistic quantum mechanics nor Dirac's relativistic wave mechanics is insufficient, and QED must be used? QED doesn't seem to be used in the electronics industry, but I'll be glad to be corrected.

And how about QCD? I thought of nuclear power, but the fact that nuclear weapons were tested in 1945, decades before QCD, makes me suspect that QCD doesn't have any unambiguous applications in nuclear engineering, either.

So I guess it's safe to say that the standard model doesn't have real-world applications, even though the seemingly more esoteric general relativity does have applications (GPS)?
