There may be no better‐known lines of least poetry than these, at least among physicists, thanks to Murray Gell‐Mann's having dubbed the elementary constituents of matter “quarks.” Gell‐Mann had come up with the sound “kwork,” but then adopted the spelling in James Joyce'sFinnegans Wake, partly because “the number three fitted perfectly the way quarks occur in nature,” as Gell‐Mann writes inThe Quark and the Jaguar: Adventures in the Simple and the Complex(W.H. Freeman, 1994).
