In 1958, Werner Heisenberg, in his 57th year, jumped the shark. At the Max Planck centennial in Berlin, he presented what others would label his Weltformel (World Formula), a final theory reducing all of physics, known and unknown, to the interactions of one elementary quantum field. This caused a substantial media splash, but eventually, especially due to the strong rejection from his old colleague and short-time collaborator Wolfgang Pauli and several other prominent physicists, the physics community concluded that Heisenberg had gone wrong, that he was pursuing a theory whose mathematical consistency was doubtful and which, even if numerical results could unambiguously be extracted from it, could not reproduce the rich particle phenomenology of the subnuclear world.
