Kausalität, Anschaulichkeit, and Individualität, or How Cultural Values Prescribed the Character and the Lessons Ascribed to Quantum Mechanics *

Abstract

Quantum mechanics is the fundamental theory of atomic and subatomic physics. Overwhelmingly, however, the creation of quantum mechanics was an enterprise of Germans and Austrians. Consequently, as a product of Germany it may appropriately be considered in relation to German culture. The "quantum mechanical variables" which Werner Heisenberg conceived, and which Max Born recognized as matrices, were probabilities of atomic transitions, or algebraic combinations and derivatives of such probabilities more precisely, probability amplitudes. The factors operating on the originators of quantum mechanics so as effectively to prescribe their representation of their theory as anschaulich were largely those presents in the discussion of Kausalitat. As regards Anschaulichkeit, the true character of the theory ran counter to the Zeitgeist, rather than, as with causality, offering physicists an opportunity to sail with the intellectual currents. Where Kausalitat was the pejorative code word in the antiintellectualist "philosophy of life," Anschauung, Anschaulichkeit, etc. were among the principal shibboleths of this Lebensphilosophie.

Weimar culture and quantum mechanics

Robert Golub, S. K. Lamoreaux

Abstract Most, but not all, of the fundamental work on quantum mechanics took place during the turbulent times of the Weimar republic, which was formed in Germany after the abdication of the Kaiser at the end of WWI. While many physicists are appalled at the implication that physical theories might, even to a limited extent, be influenced by their cultural milieu, we feel an overview of the latter might help in an overall understanding of the theory. We will see that such views were shared, to some extent, by Schrödinger. After a brief overview of the contemporary economic and cultural situation and the reactions of several of the originators of quantum theory, we pass on to Forman’s thesis regarding the influence of Weimar culture and quantum mechanics. This thesis has spurred an enormous debate, of which we give a short description.

Some philosophical lessons from quantum mechanics

James T. Cushing

[I] think I can safely say that nobody understands quantum mechanics. Richard Feynman, The Character of Physical Law Quantum mechanics [is] that mysterious, confusing discipline, which none of us really understands but which we know how to use. It works perfectly, as far as we can tell, in describing physical reality, but it is a ‘counter-intuitive discipline’… Murray Gell-Mann, Questions for the Future [The quantum] postulate implies a renunciation as regards the causal space-time co-ordination of atomic processes. Niels Bohr, Atomic Theory and the Description of Nature It should be emphasized, however, that the probability function does not in itself represent a course of events in the course of time. It represents a tendency for events and our knowledge of events. The probability function can be connected with reality only if one essential condition is fulfilled: if a new measurement is made to determine a certain property of the system. [T]he idea of an objective real world whose smallest parts exist objectively in the same sense as stones or trees exist, independently of whether or not we observe them…is impossible … Werner Heisenberg, Physics and Philosophy [In] quantum theory it is the principle of causality , or more accurately that of determinism , which must be dropped and replaced by something else.… We now have a new form of the law of causality.… It is as follows: if in a certain process the initial conditions are determined as accurately as the uncertainty relations permit, then the probabilities of all possible subsequent states are governed by exact laws.

Quantum mechanics deals with the behaviour of matter and light on the atomic and subatomic scale. It attempts to describe and account for the properties of molecules and atoms and their constituents--electrons, protons, neutrons, and other more esoteric particles such as quarks and gluons. Its concepts frequently conflict with common-sense notions derived from observations of the everyday world. Quantum mechanics has attracted some of the ablest scientists of the 20th century, and they have erected what is perhaps the finest intellectual edifice of the period. Quantum mechanics is concerned with phenomena that are so small-scale that they cannot be described in classical terms. The history of quantum mechanics may be divided into three main periods. The first began with Planck's theory of black-body radiation in 1900; it may be described as the period in which the validity of Planck's constant was demonstrated but its real meaning was not fully understood. The second period began with the quantum theory of atomic structure and spectra proposed by Niels Bohr in 1913. True quantum mechanics appeared in 1926, reaching fruition nearly simultaneously in a variety of forms--namely, the matrix theory of Max Born and Werner Heisenberg, the wave mechanics of Louis V. de Broglie and Erwin Schrodinger, and the transformation theory of P.A.M. Dirac and Pascual Jordan.

The invention of quantum mechanics—matrix mechanics

Robert Golub, S. K. Lamoreaux

Abstract Driven by the idea that a physical theory should only deal with observable quantities, Werner Heisenberg, a young post-doc working with Max Born in Göttingen, who had earlier done his Ph.D. work under Sommerfeld in Munich, was led to introduce a new type of object which represented the transitions between Bohr-Sommerfeld orbits. Max Born realized and recognized these objects as matrices. Together with Pascual Jordan, another post-doc, they worked out a complete theory, matrix mechanics. They completed this work in a few months. We discuss the role of matrix mechanics in the development of quantum mechanics.

The Historical and Physical Foundations of Quantum Mechanics

Robert Golub, S. K. Lamoreaux

Abstract Following the path by which humanity learned quantum mechanics can lead to an improved understanding of the theory and the origins of its perceived limitations. Our goal is to retrace the development by investigating primary sources, including original published papers and letters, with attention to their timing and influence. Quantum mechanics began in 1900 with the introduction of Planck’s constant, which lead to the “old” quantum theory and Bohr’s model of the atom. With the introduction of matter waves in 1924, a second more intense period began. By 1928 the complete fundamental structure of quantum mechanics was established with the introduction of the Schrödinger equation, the proof of its equivalence to Heisenberg’s matrix mechanics, and the introduction of the relativistic Dirac equation. The theory retains the same essential form today, fueling the technological revolution that began in the last century. We culminate with an introduction to quantum information and computing. This completely new physical scientific paradigm was developed largely in Germany during a period of enormous social, economic, and political upheaval—in a hostile intellectual environment—that parallels the overturning of classical physics. It is striking that all the problems debated today were immediately recognized by the founders of the theory and instructive to see how they dealt with the various issues. We emphasize the centrality of the often neglected second quantization form of the theory for questions of interpretation and give a detailed examination of von Neumann’s widely misunderstood hidden variable theorem.
