RELATIVITY GROUPOID INSTEAD OF RELATIVITY GROUP [PDF]
International Journal of Geometric Methods in Modern Physics, 2007 In 1908, Minkowski [13] used space-like binary velocity-field of a medium, relative to an observer. In 1974, Hestenes introduced, within a Clifford algebra, an axiomatic binary relative velocity as a Minkowski bivector [7, 8]. We propose to consider binary relative velocity as a traceless nilpotent endomorphism in an operator algebra. Any concept of a

Spatial Directions, Anisotropy and Special Relativity [PDF]
, 2011 The concept of an objective spatial direction in special relativity is investigated and theories assuming light-speed isotropy while accepting the existence of a privileged spatial direction are classified.

Konštruktivizmus, realizmus a obrat k jazyku
Filosofický časopis, 2021 This paper focuses primarily on the realism-constructivism debate. Firstly, I clarify Goodman’s three main arguments for constructivism, and then I deal with the critical response to this doctrine by proponents of Devittian common-sense realism and ...

A logic road from special relativity to general relativity
, 2011 We present a streamlined axiom system of special relativity in first-order logic. From this axiom system we "derive" an axiom system of general relativity in two natural steps. We will also see how the axioms of special relativity transform into those of

Relativistic kinematics beyond Special Relativity
, 2012 In the context of departures from Special Relativity written as a momentum power expansion in the inverse of an ultraviolet energy scale M, we derive the constraints that the relativity principle imposes between coefficients of a deformed composition law,

Wittgenstein's Thought Experiments and Relativity Theory [PDF]
, 2019 In this paper, I discuss the similarity between Wittgenstein’s use of thought experiments and Relativity Theory. I begin with introducing Wittgenstein’s idea of “thought experiments” and a tentative classification of different kinds of thought ...

ξRϕ2 coupling, cosmological constant and quantum gravitational corrections to Newton’s potential
Physics Letters BThis letter investigates the contribution of the −gξRϕ2 non-minimal interaction to the long range gravitational potential for massive scalar fields, found from the non-relativistic limit of the 2-2 scattering amplitude with graviton exchanges.

Seeking for the observational manifestation of de Sitter Relativity
, 2016 The de Sitter invariant special relativity is a natural extension of the usual Einstein special relativity. Within this framework a generalization of special relativity (SR) for the de Sitter space-time introduces a new length scale $R$, serving an ...

Black coffee. Marcel Duchamp’s pataphysical sensism
Relief: Revue Électronique de Littérature Francaise, 2016 Duchamp’s readymade is usually interpreted as a bold and cerebral emancipation of modern art from the material, the craft and natural beauty, and the discovery of the continent of conceptual art.

Interstellar travel guide: Chronicles of a violent universe
Mètode Science Studies Journal: Annual Review, 2017 In contrast to observations from our local viewpoint, the universe is extremely violent. Explosions of massive stars, X-ray and gamma-ray binary stars, and active galaxies are related to the presence of compact objects such as neutron stars or black ...
