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.....

Berlin: Springer, 1943; 1943; 1944. First edition of Heisenberg’s S-matrix approach to the study of elementary particles, complete in three parts (a fourth part was written but not published). Although S-matrix theory was abandoned after the War due to the success of quantum electrodynamics and quantum chromodynamics, it again became..... More
Item #3530
Berlin: Julius Springer, 1922. First edition of Heisenberg’s first published paper, describing his ‘core model’ of the atom and its application to solve the problems of the multiplet structure in atomic spectra and the anomalous Zeeman effect, which had defeated all previous attempts. “Just a year after entering Sommerfeld’s program..... More
Item #3527
Berlin: Julius Springer, 1928. A remarkable association copy, from the library of Niels Bohr, of Heisenberg’s solution of the problem of ferromagnetism. Bohr and Heisenberg are also linked by the subject matter of the present work. In his doctoral thesis Studier over Metallernes Elektrontheori (1911), Bohr proved what was later..... More
Item #3526
Berlin: Julius Springer, 1929-30. A fine set, in the original wrappers, of the two papers in which Heisenberg and Pauli gave “for the first time the foundations for quantum electrodynamics in the way we know it today.” (Abraham Pais). “Three years before the discovery of the positron Heisenberg and Pauli.....
