So I've finally memorized a solution to the Rubik's Cube. (I may be speaking too soon; let's see if the move I could never remember is still in my head tomorrow.)
I'm very slow, though. It's not the most efficient solution.
That got me thinking. There are pool hustlers, who act like they're no good at pool, start taking bets, and then all of a sudden are really good. If someone could solve the Rubik's cube really quickly, could they make money off it as a Rubik's cube hustler? Bring the cube somewhere where there are people, act like you can only solve it slowly, take bets, and then solve it quickly.
It just might work.
It would be crucial to find the right audience, though -- somewhere where people are familiar with the cube. So a bar, the typical place for pool hustling, wouldn't work. The right math department might work. But not mine -- I have readers within my department, and I'm pretty sure I've given too much away by making this post. Fortunately I don't have the skill to pull this off anyway.
