The Physics Teacher
This month's cover suggests a Russian doll metaphor for the canonical particle hierarchy—inside molecules are atoms, which house nuclei, which consist of protons and neutrons, which are composed of quarks and gluons ... but what lurks within? For some clues, see “And So Ad Infinitum: The Search for Quark and Lepton Substructure” by Don Lincoln. (cover art by Reidar Hahn, Fermilab)
