Breaking news from the International Symposium on Symbolic and Algebraic Computation in Waterloo, ON (I’m not making this up): any Rubik’s Cube (remember these things?) can be solved in less than 26 moves:
The study brings scientists one step closer to finding the so-called “God’s Number” which is the minimum number of moves needed to solve any disordered Rubik’s cube.
It is so named because God would only need the smallest number of moves to solve a cube. Theoretical work suggests that God’s Number is in the “low 20s”.
While I’m a bit flabbergasted that a toy is being studied so seriously, I’m also fascinated. More here.
Does this mean that somewhere a couple grad students and a network of computers are trying to figure out how many licks it takes to get to the center of a Tootsie Roll? ‘Cause that damn Mr. Owl always screwed up previous studies:
