scientists have created a computer algorithm that will solve a Rubik's Cube puzzle of any size. In a 3 x 3 x 3 puzzle, there are 43 quintillion possible moves. Cubes of larger dimensions would have so many possible moves that ordinary humans cannot immagine how big the quantity really is. Since the cube was introduced in the 1970s and was a popular craze in the 1980s, it has certainly taken a long time to solve this burning issue. Much, much longer than my son, Brian, took when he was a very young boy. We bought Rubik's Cubes for our children thinking that it might keep them occupied for a while. We rearrange the squares of the cube so the colors on the sides of the cube appeared to be randomly arranged. Brian was handed a cube and asked if he could fix the cube so that all the colors on each section of the cube's side were the same. I assumed that would keep him busy for months. About ten minutes later he came to show me the solved puzzle. I think he was about five years old at the time. I was stunned. I had never been able to solved the puzzle at all. Before I started to ask Brian if Einstein's Theory of Relativity was correct something caught my eye. One of the colored stickers was slightly askew. After quizzing Brian, I learned he had simply pealed all the colored stickers off and rearranged them. That was really an "out-of-cube" solution that was just as fast the the computer solution just found.
