The environmental effects in the origin of angular momenta of galaxies
2011
We study the galaxy alignment in the sample of very rich Abell clusters located in and outside superclusters. The statistically significant difference among investigated samples exists. We found that in contrast to whole sample of cluster, where alignment increase with the cluster richness, the cluster belonging to the superclusters does not show this effect. Moreover, the alignment decreased with the supercluster richness. One should note however that orientations of galaxies in analyzed clusters are not random, both in the case when we analyzed whole sample of the clusters and only clusters belonging to the superclusters. The observed trend, dependence of galaxy alignment on both cluster …
THE ROLE OF CONCEPTUAL FOUNDATIONS OF QUANTUM THEORY IN THE DIALOGUE BETWEEN SCIENCE AND RELIGION
2001
A recent development in the understanding of conceptual foundations of quantum theory is discussed, giving particular attention to the analysis of the so called Schroedinger’s cat paradox. The solution of this problem in the frameworks of Everett-Wheeler many-worlds interpretation of quantum mechanics is considered, as well as the philosophical and theological consequences following from this interpretation. The recommendations are given, concerning the use of questions related with conceptual foundations of quantum theory in the education when introducing students and senior class pupils in problems of the dialogue between science and religion. KEY WORDS: science, religion, dialogue, found…
The Tenth Article of Ettore Majorana
2006
This year is the centenary of the birth of Ettore Majorana, one of the major Italian physicists of all times. In this note we briefly sketch a few biographical details about Ettore Majorana and introduce and discuss the main points of Majorana's 10th article. In his article Majorana explicitly considers quantum mechanics as an irreducible statistical theory because the theory is not able to describe the time evolution of a single particle or atom in a precise environment at a deterministic level. This lack of determinism at the level of an elementary physical system motivated him to suggest a formal analogy between statistical laws observed in physics and in the social sciences. We hope the…

Chronology and Outlook
2018
The following chronology places emphasis on the basics and on interpretations of quantum physics; it should not be considered to be a history of quantum physics as a whole. In particular, the special developments within quantum field theory, and the advances in particle physics which grew out of them, are not included. However, along with the interpretations which were given a detailed treatment in earlier chapters (Copenhagen, GRW, Everett, Bohm), a number of other approaches are briefly mentioned here. They could not be treated in detail in the rest of the book.
The Dunkl–Williams constant, convexity, smoothness and normal structure
2008
Abstract In this paper we exhibit some connections between the Dunkl–Williams constant and some other well-known constants and notions. We establish bounds for the Dunkl–Williams constant that explain and quantify a characterization of uniformly nonsquare Banach spaces in terms of the Dunkl–Williams constant given by M. Baronti and P.L. Papini. We also study the relationship between Dunkl–Williams constant, the fixed point property for nonexpansive mappings and normal structure.
Coxeter on People and Polytopes
2004
H. S. M. Coxeter, known to his friends as Donald, was not only a remarkable mathematician. He also enriched our historical understanding of how classical geometry helped inspire what has sometimes been called the nineteenth-century’s non-Euclidean revolution (Fig. 35.1). Coxeter was no revolutionary, and the non-Euclidean revolution was already part of history by the time he arrived on the scene. What he did experience was the dramatic aftershock in physics. Countless popular and semi-popular books were written during the early 1920s expounding the new theory of space and time propounded in Einstein’s general theory of relativity. General relativity and subsequent efforts to unite gravitati…
