The asymmetry of nature under a'reversal of time'(that is, a reversal of motion and change)
appears only too obvious to us, as it deeply affects our own form of existence. If physics is to …

The first edition (2001) of this title quickly established itself on courses on the philosophy of
time and space. This fully revised and expanded new edition sees the addition of chapters …

Numerous approaches to a quantum theory of gravity posit fundamental ontologies that
exclude spacetime, either partially or wholly. This situation raises deep questions about how …

This book concerns the foundations of Quantum Gravity, in particular from a conceptual point
of view. It provides a self-contained introduction to this topic, resting on particular features of …

At the heart of quantum mechanics lies the wave function, a powerful but mysterious
mathematical object which has been a hot topic of debate from its earliest stages. Covering …

I address the problem of indefiniteness in quantum mechanics: the problem that the theory,
without changes to its formalism, seems to predict that macroscopic quantities have no …

2.1. 1 Prologue Any branch of physics will pose various philosophical questions: for
example about its concepts and general framework, and the comparison of these with …

Recent work has shown that dispersion relations with Planck scale Lorentz violation can
produce observable effects at energies many orders of magnitude below the Planck energy …

There is a philosophical tradition of arguing against presentism, the thesis that only
presently existing things exist, on the basis of its incompatibility with fundamental physics. I …

This chapter reviews effective field theory (EFT) techniques, focusing on the intertheoretic
relations between low-energy effective theories and their high-energy counterparts. It …
