Gribbin (1989: 278):
Whatever its basis in "reality", however, the quark model very neatly explains the interactions of the particle world. The everyday particles, the proton and neutron and the pions that carry the strong force, can all be described simply in terms of two quarks, which are given arbitrary labels to distinguish them from one another. One is called "up" and the other is called "down". The names have no significance; physicists could just as well, if they wished, call one quark "Alice" and the other "Albert".
