 == Particle physics ==
 The '''Standard Model''' of particle physics is a theory concerning the electromagnetic, weak, and strong nuclear interactions, as well as classifying all the subatomic particles known. The Standard Model recognizes 24 different fermions – six quarks, six leptons, and their antiparticles
 '''Fermion''' – any particle characterized by Fermi–Dirac statistics with half integer spin. These particles obey the Pauli exclusion principle. Fermions include all quarks and leptons, as well as any composite particle made of an odd number of these, such as all baryons and many atoms and nuclei. Fermions differ from bosons, which obey Bose–Einstein statistics
