The Man Who Found God's Number
David A. Joyner · College Mathematics Journal · 2014
SummaryThis is a tale of two problems. For years, Tom Rokicki worked to determine the exact value of God's number for the Rubik's Cube (the smallest number of moves needed to solve the cube in the worst case), a very difficult problem. By the time he solved this, Tom was completely deaf. Digitizing human hearing, and then implementing that into a medical device, is also a very difficult problem. Thanks to recent medical advances, Tom's hearing was restored about the same time that he discovered God's number.
