Thanks for the post. There’s a depth to Conway talking about his most commonly known piece of work, and his reactions to it, that gives one a lot to think about.<p>Also, this is the second time this weekend that I’ve heard John Conway refer to Scientific American. I used to be a regular reader some twenty years or so ago. Is it worth looking into again?
