Quantum chromodynamics observed particles make isospin and SU(3) multiplets. The approximate flavor symmetries do have associated gauge bosons, observed particles like the rho and the omega, but these particles are nothing like the gluons and they are not massless. They are emergent gauge bosons in an approximate string description of QCD. The dynamics of the quarks and gluons are controlled by the quantum chromodynamics Lagrangian. The gauge invariant QCD Lagrangian is where formula_1 is the quark field, a dynamical function of spacetime, in the fundamental representation of the SU(3) gauge group, indexed by formula_2; formula_3 is the gauge covariant derivative; the γ
3 Quarks Daily had reached thirty-five thousand. Since then, "3 Quarks Daily" has culled content from hundreds of sources, from blogs such as Salon, Science Daily, and The Huffington Post, from major publications such as "The New York Times", "Nature", and "The Guardian", to smaller outlets such as "Guernica Magazine", "The Awl", and "The American Scholar". The name "3 Quarks Daily" comes from the elementary nuclear particles of physics which in turn were named after the word "quark" which James Joyce had used in Finnegans Wake. The confluence of references to both science and literature in a single word suited the intent of
