Who's Afraid of Background Independence? [PDF]

, 2008
Background independence is generally considered to be ‘the mark of distinction’ of general relativity. However, there is still confusion over exactly what background independence is and how, if at all, it serves to distinguish general relativity from ...

Gravitation without the equivalence principle

, 2003
In the general relativistic description of gravitation, geometry replaces the concept of force. This is possible because of the universal character of free fall, and would break down in its absence.

Does Quantum Mechanics Clash with the Equivalence Principle – and Does it Matter? [PDF]

, 2010
With an eye on developing a quantum theory of gravity, many physicists have recently searched for quantum challenges to the equivalence principle of general relativity.

Covariant thermodynamics & relativity

, 2011
This thesis deals with the dynamics of irreversible processes within the context of the general theory of relativity. In particular, we address the problem of the `infinite' speed of propagation of thermal disturbances in a dissipative fluid.

Analyzing gravitational waves with general relativity

Comptes Rendus. Physique, 2019
After a short review of prominent properties of gravitational waves and of the newly born gravitational astronomy, we focus on theoretical aspects. Analytic approximation methods in general relativity have played a crucial role in the recent discoveries of gravitational waves.

The fate of presentism in modern physics [PDF]

, 2011
There has been a recent spate of essays defending presentism, the view in the metaphysics of time according to which all and only present events or entities exist.

Collision of Traditions. The Emergence of Logical Empiricism Between the Riemannian and Helmholtzian Traditions [PDF]

, 2013
This paper attempts to explain the emergence of the logical empiricist philosophy of space and time as a collision of mathematical traditions. The historical development of the ``Riemannian'' and ``Helmholtzian'' traditions in 19th century mathematics

General covariance from the perspective of Noether's theorems [PDF]

, 2002
Analysis of Emmy Noether's 1918 theorems provides an illuminating method for testing the consequences of coordinate generality, and for exploring what else must be added to this requirement in order to give general covariance its far-reaching physical ...

Relativity and Gravitation : 100 Years After Einstein in Prague

, 2014
In early April 1911 Albert Einstein arrived in Prague to become full professor of theoretical physics at the German part of Charles University. It was there, for the first time, that he concentrated primarily on the problem of gravitation. Before he left
