PHYSICS

The relationship between quantum theory and spacetime theory is famously troublesome. The picture of the world offered by physics is fractured along an indistinct fault line separating the quantum and the classical domains, and for decades there has been no clear and certain answer as to how the fracture is to be repaired. The goal is a quantum theory of gravity which, one hopes, will modify quantum mechanics and/or classical general relativity in such a way as to illuminate several outstanding problems in physics and cosmology. For about the last ten years I've struggled to try and understand this problem in my own way, inside a scheme that makes intuitive as well as formal sense. The following essays explore some different aspects of that overarching programme

Quantum Gravitational Mechanics - a Fantasia on the Possible Shape of a Future Theory (2007-9)

The Meaning of Length-scale: Radical v.Constructive Quantisation (2003)
