Julian Barbour - Relational Space and Time

Space and time appear in charts as axes oblivious to the points they demarcate. Similarly, we may feel that we, and all the objects of our worlds, are like such points - and spacetime is a container in which we sit.
Julian Barbour is a physicist who has spent six decades arguing against this. He takes the relationist approach of Leibniz and Mach: there is no space without objects and no time without change. Rather space is just the geometric relationships between things.
Julian has pioneered theories that recover the predictions of Newtonian mechanics and General Relativity that drop their invocation of imperceptible space, time, and spacetime. Recently he has taken an iconoclastic approach to the arrow of time - looking to a new measure of structure, complexity, and the expansion of the universe instead of the traditional accounts in terms of entropy.
