<p>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.</p>

In the <a href="https://plus.maths.org/content/john-conway-discovering-free-will-part-i">previous article</a>, John Conway lead us through the early days of quantum physics and explained why the non-predictive nature of this theory worried some physicists, in particular, Albert Einstein. Einstein believed that physical properties, such as the position and momentum of quantum particles, have definite, fixed values whether those properties have been measured or not.<p><a href="https://plus.maths.org/content/john-conway-discovering-free-will-part-ii" target="_blank">read more</a></p>https://plus.maths.org/content/john-conway-discovering-free-will-part-ii#commentsFrontiers of physicsmathematical realityEPR paradoxfree willquantum physicsTue, 27 Dec 2011 13:55:02 +0000Rachel5588 at https://plus.maths.org/contentJohn Conway – discovering free will (part I)

<p>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.</p>

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 how a particular, odd, detail of the world worked. Using a thought experiment involving quantum particles they were investigating the interaction of three important consequences from quantum physics and relativity.
