More than a century ago, a great German mathematician by the name of Cantor discovered the theory of infinite numbers. Two thousand years ago, Archimedes founded the theory of real numbers that we normally use. The “surreal numbers” include both. When I discovered them, I went around in a permanent daydream for six weeks thinking about how the explorer Cortez looked out over the Pacific and saw a world that no Westerner had ever seen before. Nobody had ever seen what I saw before. Although it was totally abstract, it was very real. Abstract things can be real. Numbers can be realer than physical objects. It was an amazing new world of numbers that I discovered, more than numbers.
