From Atoms to Quarks
Program 151
Electron waves confined by electric attraction
to the nucleus help resolve the dilemma of the atom and account for the periodic
table of the elements. Nucleons themselves obey a kind of period table,
following inner rules that lead to the idea of quarks. As to the question of how
you can be in two places at once, when you're not anywhere at all, it is left to
the reader as an exercise.
