	'''Joseph C. Lucas''' is an American physicist and independent researcher, and the author — with his father '''[[Charles William Lucas\|Charles W. Lucas, Jr.]]''' — of the '''physical geometrical packing model of the atom and nucleus''' that forms the atomic-structure component of the [[Common Sense Science]] programme.		'''Joseph C.

	He then measured the '''relative binding strength''' of each configuration, mounting ring magnets on pegs, removing one peg, and weighing the force needed to pull its magnet away — holding the board on edge to eliminate friction. Two results followed. Great circles of '''four''' magnets bind most tightly, which he offered as the physical origin of '''valence''' behaviour in chemical bonding. And great circles of '''ten or more''' show no more tendency to bind in a circle than an odd number does — so no shell of 50 should exist, and the atom should have only four shell sizes: '''2, 8, 18, 32'''. This is his explanation for why the Periodic Table has seven periods and stops where it does.

-"Physical Model for Atoms ..."
+His contribution is a specific and unusually concrete one. Taking [[David L Bergman|Bergman]]'s toroidal ring electron as given, Lucas asked what happens when such objects — real, finite-sized rings of circulating charge, each carrying a magnetic dipole — are packed around a nucleus. Using '''combinatorial geometry''' constrained by results he obtained from '''physical experiments with ring magnets''', he derived the sizes of the successive electron shells as '''2, 8, 18 and 32''' — the shell structure actually exhibited by the Periodic Table — together with an argument for why the table has '''exactly seven periods''' and no shell of 50. The same packing analysis was then applied to protons and neutrons, yielding the nuclear magic numbers and an account of nuclide spin.
