So: if you're the author of these instructions, or if you know who is, drop me a note! I'll be happy to credit the authors, I just can't find their names.Īnd if I do find my copy of the instructions at some point, I'll update this post. I spent some time looking around online to see if I could come up with any likely candidates, but couldn't find anyone. Unfortunately, I have no idea who they were. I learned almost all of the move-sequences below from the Santa Cruz math professors who wrote the instructions I memorized. At some future time, if I do some more polishing, I may post a revised version. So I'm just gonna go ahead and publish what I've got. But knowing me, if I wait to finalize and polish these notes, it'll take me years to post them. ![]() I haven't yet taken the time to write up these notes as a completely detailed solution, and I haven't made the illustrations that would make them much easier to follow. ![]() I was talking with a young friend about cubing a couple of weeks ago, and lamenting my inability to find those instructions-and it dawned on me that I could reconstruct them. And I started trying to find the photocopied instructions that I had learned from, but even though I've seen those pages lying around my house dozens of times over the years, every search in the past year or two has been fruitless. And then a couple years ago, some of my friends' kids started getting interested. I remained vaguely interested in the world of cubing, but the mathy discussions of it were over my head (I still have the 1981 edition of David Singmaster's Notes on Rubik's Magic Cube, but I never read it all the way through), and most of the algorithms I saw were neither as fast nor as elegant as the ones I knew, so I mostly set cubing aside. Being able to solve the Cube was also a good party trick I did it for my family enough times that one of my uncles became convinced that I could solve it behind my back. So I practiced and memorized the solution, and got fairly fast at it, and went on to place second (iIrc) in my 8th-grade cube-solving competition. Up to that point, I think I had been able to solve one face at a time, but I had never been able to solve the whole cube. I'm not sure whether the Cube had become popular yet at that point, but I believe it was before the Simple Solution was published it was certainly before I had seen a solution. When he came home, he brought with him a few photocopied sheets of paper on which were described a solution to the Rubik's Cube, written by the professors who'd taught the class. I vaguely think the topic may've been functors. We had no idea that within a couple of years, it would be one of the most popular toys in the world.Īt some point in the next couple of years, my father went down to Santa Cruz to take a math class there. They gave us a gift from Hungary: a plastic toy cube with a different color on each of its rotating faces. Sometime in the late 1970s, I think, my family sublet a room in our house to a Hungarian math professor and his family.
