Rubik’s Cube

Recently, I’ve begun sending Katy emails entitled “Math News Today (MNT)” since I always seem to send her anything mathematical (mathemagical?) that I run across. This one, though, was too good to keep in private email. First off, the news: Tomas Rokicki has brought the moves required to solve a Rubik’s Cube down to just 25.

But what’s more important than the news is one of the comments attached to the Slashdot article:

I consider a Rubik’s Cube to be “solved” regardless of its starting position. I subscribe to the Fred Rogers solution: it’s fine just the way it is.
