- How hard is it to solve a Rubik's Cube?
- When can you say that your Rubik's Cube is completely scrambled?
- Why might the answer depend on where you went to school?
- What interesting mathematical questions are involved?
I do not recall having seen this matrix before, but I will not be surprised to learn that somebody else already knows all about it, especially if that person's name is Nick.... read more >>
Rubik's Cube is one of the great mathematical puzzles of all time. Most people are just interested in solving Rubik's Cube rapidly, but deeper investigation reveals a rich mathematical and computational structure. A digital Rubik's Cube simulator provides a laboratory for the study of linear algebra, group theory, data structures and computer graphics.... read more >>
