Is a Hadron a Quasiparticle in Condensed Matter Physics?

[Demystifier]

But physics is about predictive formalisms, not about profound truths. The latter are reserved for the informal interpretation of the formalism.

To defend 't Hooft I would say that physics is not only about predictive formalism, but also about ideas that justify that formalism. Indeed, the 't Hooft lectures on QFT (as pretty much any other QFT textbook) starts with some heuristic ideas and ends up with some predictive formalism.

Sure, lots of heuristics precedes the formulation of a working model.

The point that I had wanted to make is that atyy's initial quote in post #25 was taken out of context and doesn't make the standard model ''condensed matter in spirit" - it only creates an informal bridge between the two.

That post was written by atyy, not me. I agree that it only makes an informal bridge.
