People come in all shapes and sizes, with all kinds of likes and dislikes. Some people (and I’m certainly one of them) like to try to figure out how stuff works. That desire is certainly what led me to be a scientist, and to make a career out of trying to figure out how stuff works. For me, part of this is that I look around and see what appears to be very disorderly world. A bird’s eye view of a city shows people going in all kinds of directions, moving in different ways from here to there, and it looks like chaos. But pull any of those individuals aside, and ask what they’re doing, where they’re going, and they’ll have a story to tell and a reason (maybe not always a good one) that they’re doing what they’re doing. When those individual reasons are all known, the world seems, and feels (to me) more orderly and less chaotic. I crave order in things. That’s just who I am.
