Round 5: Tossup 6

This physicist and an alphabetically-later collaborator developed a set of electrodynamic equations that set an upper limit on the self-energy of a point charge to avoid divergences in Maxwell electrodynamics. This physicist developed a coordinate chart to describe the worldlines of Langevin observers on a rotating disk, which must have constant orthogonal spacetime distance to satisfy this physicist’s relativistic formulation of rigidity. While at Göttingen, (10[1])this physicist and Heisenberg developed the (10[1])matrix representation of quantum physics. This physicist proposed that the squared (10[1])magnitude of a wave function equals the probability (10[1])of finding (10[1])a particle. (-5[1])For 10 points, name this German physicist who names an approximation (-5[1])that fixes nuclei in space along with J. Robert Oppenheimer. (10[1])■END■ (10[1]0[1])

ANSWER: Max Born [accept Born rule or Born rigidity or Born coordinates or Born–Infeld model or Born–Oppenheimer approximation]
