Rubik's Speed Cubing - from the New York Times
Dr. Jessica Fridrich likes to tackle problems that might seem impossible to others. Rubik’s Cube is an example. She has created what is possibly the world’s most common strategy for speed-solving the popular puzzle, and is the subject of a YouTube video.
The Fridrich Method deals with more than 50 algorithms, which are rotations of the cube, and herein lies the mathematics of her method. Many of the world’s fastest speedcubers know more than 100 methods, and can solve a scrambled cube in mere seconds.
Here’s the link to the New York Times article about Dr. Fridrich.
