American phycisist Murray Gell-Mann first named the discovered particle after the sound of a duck (no idea why), then came across this little poem in 'Finnegans Wake' about King Mark, which supplied the spelling.
Three quarks for Muster Mark!
Sure he has not got much of a bark
And sure any he has it's all beside the mark.
Weird how experimental literature is supplying the vocabulary for subatomic physics. Perhaps metaphors are taking over at the limits of our understanding...
