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.


In this, the third part of our interview, John Conway continues to explain the Free Will Theorem and how it has changed his perception of the Universe.


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.

Runners and cyclists can tolerate heat and cold but the thing they dislike most is wind. They know it produces slower times. Can we show them why?

In this appendix we give a gist of the proof of the Kochen-Specker Theorem.

The festive season can only mean one thing... getting together with the family! You might not be able to choose your family, but at least now you'll know exactly what you share in common!
