Nobel Laureate's brilliant early treatise on Einstein's theory consists of his original 1921 text plus retrospective comments 35 years later.

Recent literature on Bohm's alternative to mainstream quantum mechanics may create the misleading impression that, except for perfunctory dismissals, the theory was ignored by the physics community in the years immediately following its proposal. As a matter of fact, Einstein, Pauli, and Heisenberg all published criticisms of Bohm's theory, explaining their reasons for not accepting the theory. These criticisms will be discussed and evaluated in this article.

This article analyses an episode in the earlyhistory of quantum theory: the controversy betweenPauli and Heisenberg about the anomalous Zeemaneffect, which was a main stumbling block for the oldquantum theory of Bohr. It is argued that theindividual philosophical views of both Pauli andHeisenberg directed their attempts to solve theanomaly and decisively influenced the solutions theyproposed. The results of this case study arecompared with the assertions of four theories ofscientific change, namely those of Kuhn, Lakatos,Laudan and Giere.

In this paper I argue that demonstrative induction can deal with the problem ofthe underdetermination of theory by evidence. I present the historical case studyof spectroscopy in the early 1920s, where the choice among different theorieswas apparently underdetermined by spectroscopic evidence concerning the alkalidoublets and their anomalous Zeeman effect. By casting this historical episodewithin the methodological framework of demonstrative induction, the localunderdetermination among Bohr's, Heisenberg's, and Pauli's rival theories isresolved in favour of Pauli's theory of the electron's spin.

This contribution explores Wolfgang Pauli's idea that mind and matter are complementary aspects of the same reality. We adopt the working hypothesis that there is an undivided timeless primordial reality (the primordial "one world''). Breaking its symmetry, we obtain a contextual description of the holistic reality in terms of two categorically different domains, one tensed and the other tenseless. The tensed domain includes, in addition to tensed time, nonmaterial processes and mental events. The tenseless domain refers to matter and physical energy. This concept implies that mind cannot be reduced to matter, and that matter cannot be reduced to mind. The non-Boolean logical framework of modern quantum theory is general enough to implement this idea. Time is not taken to be an a priori concept, but an archetypal acausal order is assumed which can be represented by a one-parameter group of automorphisms, generating a time operator which parametrizes all processes, whether material or nonmaterial. The time-reversal symmetry is broken in the nonmaterial domain, resulting in a universal direction of time for the material domain as well.

The article recalls the anti-molecular transformation of biology 100 hundred years ago. The author recounts protein chemist Wolfgang Pauli’s announcement of a new era of biomedical research in 1905. Colloidal chemistry was supposed to be the center of the era described by Pauli. The author discusses the aspects that remained from the three decades in which colloidal science exerted a great influence on biological and biochemical research.

Carl Jung coined the term "synchronicity" to describe meaningful coincidences that conventional notions of time and causality cannot explain. Working with the great quantum physicist Wolfgang Pauli, Jung sought to reveal these coincidences as phenomena that involve mind and matter, science and spirit, thus providing rational explanations for parapsychological events like telepathy, precognition, and intuition. Synchronicity examines the work of Jung and Pauli, as well as noted scientists Werner Heisenberg and David Bohm; identifies the phenomena in ancient and modern mythologies, particularly the Greek legend of Hermes the Trickster; and illustrates it with engaging anecdotes from everyday life and literature.

"Symmetry" was one of the most important methodological themes in 20th-century physics and is probably going to play no lesser role in physics of the 21st century. As used today, there are a variety of interpretations of this term, which differ in meaning as well as their mathematical consequences. Symmetries of crystals, for example, generally express a different kind of invariance than gauge symmetries, though in specific situations the distinctions may become quite subtle. I will review some of the various notions of "symmetry" and highlight some of their uses in specific examples taken from Pauli's scientific oevre. This paper is based on a talk given at the conference "Wolfgang Pauli's Philosophical Ideas and Contemporary Science", May 20.-25. 2007, at Monte Verita, Ascona, Switzerland.

Wolfgang Pauli is well recognized as an outstanding theoretical physicist, famous for his formulation of the two-valuedness of the electron spin, for the exclusion principle, and for his prediction of the neutrino. Less well known is the fact that Pauli spent a lot of time in different avenues of human experience and scholarship, ranging over fields such as the history of ideas, philosophy, religion, alchemy, and Jung's psychology. Pauli's philosophical and particularly his psychological background is not overt in his scientific papers and was unknown even to many specialist scholars until a number of enthralling and perplexing documents of a close interaction between Wolfgang Pauli and the psychologist Carl Gustav Jung became publicly available in recent years. Both scholars stressed the inseparability of the physical and the psychical and called upon a sense of more openness toward the unconscious. Decades after his death, Pauli's innovative perspective and his vision of a wholeness of psyche and matter are more than ever before of great relevance.
