“I’m reminded reading Dear Science, that in the world of teaching I’ve inhabited and made most of my living from for three decades, the kinds of students I prefer to teach above all have been artists, athletes, and engineers. The first two—artists and athletes—understand that practice makes different. They understand that repetition is differentiation. They understand, they understand, they understand. And the third group—engineers—aren’t perplexed but rather energized by thinking the interrelations of system and structure in multiple convolutions and extensions, whatever the scale may be.”
