**A deterministic model of the free will phenomenon**

This paper solves the centuries old free will problem. Yes, it really does. For decades the debate has raged about how to explain indeterminism in our decision making. This paper demolishes the myth that our free will has anything to do with indeterminism - there is no evidence and never could be. Sadly no role for quantum theory.That still leaves the challenge of explaining the free will that we perceive. This is achieved with a standard goal seeking agent model with "independence" as a goal satisfied when the agent responds to "challenges" and changes its behaviour.

**Electrodynamics and time orientability**

The equations of electrodynamics are derived from the twisting and turning of the time direction. In many ways it follows some of the old Kaluza Klein work, but in my view it goes further than any other work in giving an origin to electromagnetism and unifying it with general relativity. Although primarily a classical result, the time reversing structures have close links with quantum theory.
