‎First printing of Heiseberg's seminal and groundbreaking paper which laid the foundation for matrix mechanics and thereby giving birth to modern quantum mechanics"" a theory that states quantum mechanics should be based ""exclusively on relationship between quantities which in principle are observable"" (From the abstract). ""The alternative, which he [Heisenberg] chose in his historic paper [the present] and which led to the development of matrix machanics, the earliest formulation of modern quantum mechanics, abandoned Bohr's description of motion in terms of classical physics altogether and replaced it by a description in terms of what Heisenberg regarded as observable magnitudes"" (Jammer, The Conceptual Development of Quantum Mechanics, P. 197).""After nearly two weeks on Helgoland, Heisenberg returned to Göttingen, where he drafted his fundamental paper ""Über die quantentheoretische Umdeutung kinematischer und mechanischer Beziehungen,"" which he completed in July. In this paper Heisenberg proclaimed that the quantum mechanics of atoms should contain only relations between experimentally observable quantities. Theresulting formalism served as the starting point for the new quantum mechanics, based, as Heisenberg's multiplication rule implied, on the manipulation of ordered sets of data forming a mathematical matrix."" (DSB)Before Heisenberg's discovery the Bohr-Sommerfeld quantum theory was the leading theory. By the early 1920's most physicists agreed that the Bohr-Sommerfeld theory had problems and that there was a need to replace it with a new quantum theory. Heisenberg's main achievement was to replace the idea of orbital path with what could be observed, namely the light emitted and absorbed by the atoms. Because of the unfamiliar mathematics which Heisenberg's new theory used, several physicists had doubts about its consistency. But Max Born soon realized that the laws, which the theory relied on, were the same as the laws, which apply to matrix algebra. In 1925 Born and his student Pascual Jordan published ""Zur Quantenmechanik"" which reformulated Heisenbergs theory in terms of matrices, in the special case of one degree of freedom. With ""Zur Quantenmechanik II"" (or the ""Three Man Paper"") published 1926, Heisenberg, Born and Jordan described the new theory in the general case of arbitrarely many freedom degrees.‎

Dr. Faxeén mit / best. Empfehl. d. verf."". Stapled spine with rust slightly affecting surrounding paper. A very fine and clean copy. Pp. (1), 578-627.‎

‎First edition in the exceedingly rare offprint - with a most attractive presentation-inscription from Heisenberg to Swedish Hilding Faxén, an important contributor to the field - of Heisenberg's doctoral dissertation on the stability and turbulence of fluid flow, which ""involved an approximate solution of the complicated equations governing the onset of hydrodynamic turbulence""(David C. Cassidy). It is widely regarded as being ""the most important early paper devoted to this subject"". (Yaglom, Hydrodynamics Instability and Transition to Turbulence).Hilding Faxén (1892 - 1970), Swedish physicist, received his doctorate in 1921 at Uppsala University with his thesis on ""the influence of the container walls on the resistance against movement by a small ball in a viscous fluid"". He formulated several basic equations mainly in hydrodynamics"" the Faxén integral, the Faxén laws, the Faxén theorems and the Faxén-Waller theory.Heisenberg and Faxén most likely met at the Institute of Theoretical Physics at the University of Copenhagen (Directed by Niels Bohr) where Heisenberg, From 17 September 1924 to 1 May 1925, studied under an International Education Board Rockefeller Foundation fellowship. Despite Sommerfeld's positive evaluation of Heisenberg's thesis - ""In the handling of the present problem, Heisenberg shows once again his extraordinary abilities: complete command of the mathematical apparatus and daring physical insight"" (Arnold Sommerfeld, evaluation of the thesis, 1923) -, the oral presentation did not go as Heisenberg could have hoped for:""Acceptance of the dissertation brought admission of the candidate to the final orals, where in this case trouble began. The examining committee consisted of Sommerfeld and Wien, along with representatives in Heisenberg's two minor subjects, mathematics and astronomy. Much was at stake, for the only grades a candidate received were those based on the dissertation and final oral: one grade for each subject and one for overall performance. The grades ranged from I (equivalent to an A) to V (an F).As the 21-year-old Heisenberg appeared before the four professors on July 23, 1923, he easily handled Sommerfeld's questions and those in mathematics, but he began to stumble on astronomy and fell flat on his face on experimental physics. In his laboratory work Heisenberg had to use a Fabry-Perot interferometer, a device for observing the interference of light waves, on which Wien had lectured extensively. But Heisenberg had no idea how to derive the resolving power of the interferometer nor, to Wien's surprise, could he derive the resolving power of such common instruments as the telescope and the microscope. When an angry Wien asked how a storage battery works, the candidate was still lost. Wien saw no reason to pass the young man, no matter how brilliant he was in other fields."" (Cassidy, Uncertainty).The result was that Heisenberg received the lowest of three passing grades in physics and the same overall grade (cum laude) for his doctorate, both of which were an average between Sommerfeld's highest grade and Wien's lowest grade.There is an interesting epilogue to the story. When Heisenberg derived the uncertainty relations several years later, he used the resolving power of the microscope to derive the uncertainty relations - and he still had difficulty with it. When Bohr pointed out the error, it led to emotional difficulties for Heisenberg. Likewise, this time a positive result came off the affair: Heisenberg's reaction induced Bohr to formulate his own views on the subject, which ultimately led to the so-called Copenhagen Interpretation of quantum mechanics.Heisenberg was awarded the Nobel Prize in Physics in 1932 ""for the creation of quantum mechanics, the application of which has, inter alia, led to the discovery of the allotropic forms of hydrogen"".Faxén was appointed professor of mechanics at the Royal Institute of Technology in Stockholm, where he remained until his retirement in 1958. In 1948 he was elected a member of the Royal Swedish Academy of Sciences.Cassidy 1924b.‎

‎First printings of these four absolutely fundamental papers, which together MARK THE TURNING POINT IN THE FABRICATION OF A NEW PHYSICS, Quantum Mechanics, also called ""Matrix Mechanics"".""In May 1925, Heisenberg took on a new and difficult problem, the calculation of the line intensities of the hydrogen spectrum. Just as he had done with Kramers and Bohr, Heisenberg began with a Fourier analysis of the electron orbits. When the hydrogen orbit proved too difficult, he turned to the anharmonic oscillator. With a new multiplication rule relating the amplitudes and frequencies of the Fourier components to observed quantities, Heisenberg succeeded in quantizing the equations of motion for this system in close analogy with the classical equations of motion.....in June Heisenberg returned to Göttingen, where he drafted his fundamental paper [the first paper offered], which he completed in July. In this paper Heisenberg proclaimed that the quantum mechanics of atoms should contain only relations between experimentally observable quantities. The resulting formalism served as the starting point for the new quantum mechanics, based, as Heisenberg's multiplication rule implied, on the manipulation of ordered sets of data forming a mathematical matrix....Born and his assistant, Pascual Jordan, quickly developed the mathematical content of Heisenberg's work into a consistent theory with the help of abstract matrix algebra [the second paper offered].Their work, in collaboration with Heisenberg, culminated in their ""three-man paper"" [""Dreimännerarbeit"" - the third paper offered] that served as the foundation of matrix mechanics. Confident of the correctness of the new theory, Heisenberg, Pauli, Born, Dirac, and others began applying the difficult mathematical formalism to the solution of lingering problems."" (DSB).In the last paper offered, the Pauli-paper, he shows that the hydrogen spectrum can be derived from the new theory. His starting-point constitutes, due to Lez, a method for integrating the classical equations of motion of a particle in a Coulomb field. Pauli's paper was received on January 17, 1926, but the main result must have been obtained before November 3, 1925, for on that date, Heisenberg writes Pauli: ""..Ich brauche Ihnen wohl nicht zu schreiben, wie sehr ich mich über die neue Theorie des Wasserstoffs freue..."" Pauli's paper convinced most physicists that Quantum Mechanics is correct. (Van der Waerden).‎

These results not only lent weight to the concept of like particles, they also showed that like particles may be indistinguishable, that is, may lose their identity, a conclusion which follows from the uncertainty relations or, more precisely, from the impossibility of keeping track of the individual particles in case of interactions of like particles.
