My friend (and several-time Gameshelf TV star) Matthew Morse is getting back into speedcubing, the ancient art of solving a thoroughly scrambled Rubik's Cube wicked fast. He started out by buying a new cube, since his old one, while a source of nostalgic affection, is too worn for competitive play.
After I got a new Cube, I promptly set out to demonstrate that I still remembered the solution I had memorized. What I found was that for two related sequences, I had forgotten which sequence did what. Which sequence to use in response to which pattern is memorized by your head, and initially I had it backwards. Once I figured it out, executing them was no problem. Performing the sequences is memorized in the hands, and they hadn't forgotten at all.
Now I'm working on developing my understanding of how the solution works. I've filled several pages of notes based on the simpler case of a 2x2x2 Cube and I expect to be able to move up to the standard 3x3x3 once I have some more details worked out.
I also bought a 4x4x4 Cube at the same time I got the new 3x3x3 Cube. It's still in the package. Truthfully, I'm a little scared of it.
Full post contains reminiscing about his original childhood time with the cube, as well as mention of Jessica Fridrich, a teenage cube prodigy who grew up to become an engineering professor at Binghamton University, and who keeps her canonical speedcubing notes prominently linked from her academic homepage.
