The author, on the basis of the history of philosophy and the history of physics, presents the history of ether. Particular attention is paid to the beliefs of Albert Einstein on the issue.

This article was written to demonstrate the meaning of non-euclidean geometry to the construction of Relativity, amd the sense of light ́s speed according to the Special Relativity, and the philosophical foundations.

The Theory of Relativity from Einstein starts from some everyday system of Cartesian space- coordinates plus a linear time-parameter, read from a good old grand-father’s clock. The theory then contemplates a group of certain homogeneous, linear transformations with constant coefficients, transformations which involve all four coordinates and which there is reason to interpret as going over the another inertial systems, that moves with constant translational velocity with respect to the first. In fact the very backbone of the theory is that all laws of nature shall be the same for every frame reached in this way, including the original one from which we started, there should be no difference or distinction in principle between all these inertial frames, any one of which can be reached from any other one by a transformation of that group a so called Lorentz-transformation. In short, all laws of nature are assumed to be invariant to Lorentz- transformation.

One of the key episodes of history of modern physics – Paul Dirac’s startling contrivance of the relativistic theory of the electron – is elicited in the context of lucid epistemological model of mature theory change. The peculiar character of Dirac’s synthesis of special relativity and quantum mechanics is revealed by comparison with Einstein’s sophisticated methodology of the General Relativity contrivance. The subtle structure of Dirac’s scientifi c research program and fi rst and foremost the odd principles that put up its powerful heuristics is scrutinized with special emphasis on the highly controversial tenet of “mathematical beauty.” It is contended that despite the relentless Dirac’s remarks denigrating the controversial role of philosophy one can trace its indirect infl uence through Arthur Eddington’s and Hermann Weyl’s whimsical mathematical models. Accordingly, the milestones of Dirac’s research programme realization in the distinctive context of the applied epistemological doctrine are indicated.

Jedna z klíčových epizod dějin moderní fyziky – překvapivý vznik relativistické teorie elektronu Paula Diraca – je analyzována z hlediska epistemologického modelu změny zralé teorie. Článek poukazuje na zvláštní charakter g y Diracova sjednocení speciální relativity a kvantové mechaniky, který se objevuje při srovnání s Einsteinovou sofi stikovanou metodologií v pozadí teorie všeobecné relativity. Rafi novaná struktura Diracova vědeckého výzkumného programu a neobvyklé principy, které vybudovaly jeho silnou heuristiku, jsou prozkoumány s důrazem na vysoce kontroverzní princip „matematické krásy“. V článku tvrdím, že navzdory neutuchajícím Diracovým poznámkám popírajícím roli fi losofi e lze vysledovat její nepřímý vliv prostřednictvím hravých matematických modelů Arthura Eddingtona a Hermanna Weyla. V souladu s tím jsou představeny hlavní body Diracova výzkumného programu z hlediska aplikované epistemologické doktríny.

The article is concerned with the generic specifics of the romaneto, a literary mode established by Czech writer Jakub Arbes, taking as its vantage point the way in which fantastic storylines operate within it. Arbes’s romanettos can be characterized by the interplay of gothic writing and science fiction. The study focuses on his most wellknown romanetto Newton’s Brain (Newtonův mozek). The analysis aims at a comparative investigation of the stolen brain motif related to the popular story of Einstein’s stolen brain and its literary repercussions.

Artykuł dotyczy wyznaczników romaneto – gatunku literackiego zapoczątkowanego przez czeskiego pisarza Jakuba Arbesa – przyjmując za punkt wyjścia sposób, w jaki rozwijają się w nim fantastyczne fabuły. Romaneta Arbesa charakteryzuje wzajemne oddziaływanie powieści gotyckiej i science fiction. Artykuł koncentruje się na najbardziej znanym romaneto Mózg Newtona (Newtonův mozek). Analiza skupia się na porównawczym rozpatrywaniu motywu ukradzionego mózgu w relacji do historii o ukradzionym mózgu Ensteina i jej literackich reperkusjach.

Since the 20th century the quantum physics has shown various phenomena, judged as “seldom and not easily understandable” by the theories of classic physics. From the beginning of the “Kopenhagener Deutung,” Einstein claimed against Heisenberg, Bohr, etc. that the particle physics lacks “physical reality.” A number of physicists have tried to clarify the labyrinth of particle as a minimal substance in the phenomena of the micro world. The entanglement of the “double particle” emitted from a π-meson in its teleportation is one of those phenomena. However, a successful new thesis has also become a target for the antithesis by deputies. Even if the “uncertainty” of an emitted light quantum that is received by the detector “either as a particle or as wave” has been reduced in our time by using probability calculations and new experimental physical facilities, the principal character of particles based on the “uncertainty relation” has not been changed. Although Heisenberg’s formula of the uncertainty relation could be “renewed” by completing certain operational components substituted by some physicists, the fundamental reality of phenomena of particle physics remain: The “physical reality” manifested by Einstein based on his glorious success of the Special and General Theory of Relativity cannot be valid in the micro-world phenomena. Pietschmann, a well-known theoretical physicist in Vienna, and Hashi, a philosopher teaching and researching interdisciplinary philosophy in Vienna, highlight the essential problems of particle physics and clarify them in regards to ontological and epistemological aspects. The dialogue has its origin in the hypothesis that the particle physics needs a logical interpretation with completely new ontological principles. In addition, the fundamental ontology of Mahayana Buddhist philosophy (without mystics) and its further development to rational philosophy of East Asia has various indications and contributions for an ontological epistemology of particle physics.
