On the one hand this story about a clever kid cutting school and rocking his Rubik's Cube is a little too "ohmygod, urban youths know math!" but at the same time it is hard not to smile as the kid in question not only explains to a stranger on the D train that solving the cube is all "just algorithms." And then when he goes on to teach the whole train what an asymptote is? Well, "the asymptote’s a bitch" just might be our phrase of the day.
