Quantum Field Theory


Coat of arms of Niels Bohr Coat of arms of Paul A.M. Dirac
In science, one tries to tell people something that no one ever knew before, in such a way as to be understood by everyone.
But in poetry, it's the exact opposite.
Paul A.M. Dirac (1902-1984; Nobel 1933)

Quarks are normally not observed alone but in composite particles known as  hadrons  of which there are two broad types:  A  meson  is a bosonic hadron consisting of a quark and an antiquark  (carrying opposite color charges).  A  baryon  is a fermionic hadron; a color-neutral combination of three quarks.
