Relativity as Support for Presentism: A Modest Evidential Argument [PDF]

open access: yes, 2013
Presentism is roughly the view that only the present exists. This view requires an absolute simultaneity relation. The special theory of relativity, however, is highly successful and does not account for absolute simultaneity.

Gravitation and relativity

open access: yes, 1976
Gravitation and Relativity generalizes Isaac Newton's theory of gravitation using the elementary tools of Albert Einstein's special relativity. Topics covered include gravitational waves, martian electrodynamics, relativistic gravitational fields and ...

Geometrizing gravity and vice-versa: the force of a formulation [PDF]

open access: yes, 2009
It is well-known that Newton’s theory of gravity, commonly held to describe a gravitational force, can be recast in a geometrical form: Newton- Cartan theory.

Teaching general relativity theory in high school: why, what and how

open access: yesRevista de Enseñanza de la Física, 2017
In this work, which is part of a wider research, the problem of teaching the General Theory of Relativity in sec-ondary school is addressed, even though this theory is scarcely addressed even in physics degree courses.

Topics in the Foundations of General Relativity and Newtonian Gravitation Theory

open access: yes, 2012
In Topics in the Foundations of General Relativity and Newtonian Gravitation Theory, David B. Malament presents the basic logical-mathematical structure of general relativity and considers a number of special topics concerning the foundations of general ...

The Nontriviality of Trivial General Covariance: How Electrons Restrict 'Time' Coordinates, Spinors (Almost) Fit into Tensor Calculus, and 7/16 of a Tetrad Is Surplus Structure [PDF]

open access: yes, 2011
It is a commonplace in the philosophy of physics that any local physical theory can be represented using arbitrary coordinates, simply by using tensor calculus. On the other hand, the physics literature often claims that spinors \emph{as such} cannot be

Time in the theory of relativity: on natural clocks, proper time, the clock hypothesis, and all that [PDF]

open access: yes, 2013
When addressing the notion of proper time in the theory of relativity, it is usually taken for granted that the time read by an accelerated clock is given by the Minkowski proper time.

Conformal Infinity

open access: yesLiving Reviews in Relativity, 2004
The notion of conformal infinity has a long history within the research in Einstein's theory of gravity. Today, 'conformal infinity' is related to almost all other branches of research in general relativity, from quantisation procedures to abstract ...

Symmetries and invariances in classical physics [PDF]

open access: yes, 2005
Symmetry, intended as invariance with respect to a transformation (more precisely, with respect to a transformation group), has acquired more and more importance in modern physics.
