50 Years after the Quark Model:
Boiling Quarks.

Bohr and Einstein, from the AIP E. Segre Visual Archives.
We all know what happened to high-energy physics after Gell-Mann's 1964 paper on the quark model. Click here for the quarks, leptons, and gauge bosons in the standard model.

Let us go back to 1964. The proton, like other hadrons, is a bound-state of the quarks. However, we are not sure about how the proton looks to a moving observer.

Quarks are confined inside a hadron. Is it possible to boil those quarks?
