The plate
Erwin Schrödinger, Quantisierung als Eigenwertproblem · Zürich, 1926
Taking up de Broglie’s idea that electrons are also waves, Schrödinger asked which standing waves the pull of a nucleus allows. For hydrogen the answer is exact, and the whole numbers that Bohr had imposed by hand emerge on their own, as naturally, he wrote, as the number of nodes on a vibrating string. Each cell slices one solution through the nucleus, bright where the electron is likely to be found. Energy rises down the rows, angular momentum across them; dark rings and spokes are nodes.
Computed, not drawn: every mark on the plate comes from the mathematics or from real data, and the type is set from the same files that go to the printer.
