Leptons: Particles that have spin quantum of 1/2 but experience no strong interactions. I get the spin part but are these wimpy unemotional particles? Give me entropy anytime. - Valerie Josephson, a fan of this web site

Well, Valerie, isn't there a book about this: "Bosons* are from Paris and Leptons are from Detroit"? Or is it Venus and Mars? - WLM, the proprietor of this web site, who grew up in Detroit! Or on Mars; I disremember which.

* Bosons are particles having integer spin that interact via the so-called strong force; protons and neutrons are examples of bosons while electrons and positrons are examples of leptons.
