discovering free will (part I) -- On August 19, 2004, John Conway was standing with his friend Simon Kochen at the blackboard in Kochen's office in Princeton. They had been trying to understand a thought experiment involving quantum physics and relativity. What they discovered, and how they described it, created one of the most controversial theorems of their careers: The Free Will Theorem. John Conway: discovering free will (part II) -- In this, the second part of our interview, John Conway explains how the Kochen-Specker Theorem from 1965 not only seemed to explain the EPR Paradox, it also provided the first hint of Conway and Kochen's Free Will Theorem. The crystallising Universe -- Explaining how time flows as the present "crystallizes" from the past, George Ellis could save the concept that the future is open and free will exists -- solving the mystery how photons can time travel along the way. This article is from the FQXi community website . Comments Free will is relative to the system which it's being evaluated from. The whole Universe can be seen as deterministic or as a free will entity, depending upon what events and from which perspective your are considering them. In http://grampsgrumps.blogspot.com/2009/05\\... I argue that free will arises naturally from the fact that most information is incompressible. In particular the information describing you is almost certainly incompressible, meaning that your behaviour can not be predicted using anything simpler than a perfect replica of you.
