Berlin: Springer, 1925; 1926. First edition, extremely rare offprints, of Born and Jordan’s explication of Heisenberg’s quantum mechanics – in their joint paper On Quantum Mechanics, which introduced matrix mechanics to the world – and the more detailed sequel with Heisenberg himself, the famous “three-man paper,” which was the first.....

Berlin: Springer, 1926. First edition of the explanation of the anomalous Zeeman effect on the basis of matrix mechanics. “By including the spin property of the electron, Heisenberg and Jordan obtained perhaps the greatest triumph of matrix mechanics: they were able to derive all observed phenomena connected with the anomalous.....

Item #6418
Berlin: Springer, 1927. First edition, extremely rare offprint, of this important paper, in which Jordan introduces his approach to quantum field theory, independent of Dirac’s, and also gives his formulation of Fermi-Dirac statistics, which he had developed earlier than both Fermi and Dirac. “Pascual Jordan is the unsung hero among.....
