I’ve always loved the choreography of complicated systems: Here’s the silent communication between ground crew and pilots.

The dance that happens to get baggage from the hold to transfer cart. Imagine how complicated it must be to sort all the bags onto the right carts and get them to the right planes for loading so that the bags (mostly!) all get to the final destinations as the passengers.

I love getting to a ballpark early to watch the groundscrew ready a field for a game. Painting the lines, wetting the infield dirt, drawing the batters boxes. There’s an order and precision to it that I find joyful in the details.
