Episode description

This episode covers chapter 2 titled "Beyond Laws of Motion?". In this chapter we explain some of the successes of the "dynanical laws + supplementary conditions" vision of physics and some of the limitations. Those limitations include the fact that the supplementary conditions - notably the initial conditions - cannot be explained under that scheme. Nor can time itself. The idea of things being possible or impossible in the universe (for example computers) may better be understood via constructor theory and there is more grist-for-my-mill when I get back on my hobbyhorse about free will (to mix some metaphors).
