Early 1981: after playing with the cube on/off for a few weeks, I woke up on a Sunday morning and said to myself: TODAY IS THE DAY THAT I WILL SOLVE THIS. 9 hours later, it was DONE! (Halfway through my grandmother came over and she wanted ...to try it. Within seconds, she ruined whatever progress I had.) I got the corners by partial luck and then figured out the edges. I didn't fully understand my algorithms. The next day it took me only 4 hours. The day after - 2 hours. Eventually I came up with an algorithm for the corners. I know that my method is slow - my fastest time is about 2 minutes. I'm resistant to learn the faster methods because I didn't figure them out myself. Erno Rubik is a great man.
Mr. Erno Rubik could be the most influential person of the 20th century.
