Freeman said we had paused here for a reason: if we visualized the city as a series of street intersections, we were now standing at the center of New York. In other words, if the city was a giant cookie tray and you put a tiny weight on every intersection, the tray would balance on this point. (Intersections aren’t evenly distributed across the boroughs, which is why this centroid is different from the one at the start of the walk.) It was a very Freeman moment: you focus on a place not because it’s inherently interesting but because it has some significance in a larger mathematical system, then you find what’s interesting afterward.
