Darwin spent his life trying to find the law that governs evolution. He knew it existed — he just never found it. Stephen Wolfram thinks he has. And it explains a lot more than evolution.  
  
Stephen Wolfram is a mathematician, complexity theorist, and the mind behind Wolfram Alpha and Mathematica — someone who has spent his career finding the hidden rules underneath reality itself.   
  
The same principle that explains why evolution never gets stuck, why you have free will despite living in a deterministic universe, and why the laws of physics are the way they are turns out to say something profound about what it means to be alive.
