When I was little, having just moved to the U.S. from Italy and going from not having a car to spending a lot of time in the car, I was fascinated by the way that power lines appear to move in and out of one another as I looked out the window during car trips. If you can’t visualize what I mean, try to pay attention to it and observe the power lines the next time you’re driving down a country road (as a passenger). The optical illusion is quite fascinating, mesmerizing, and beautiful in some way. It brings to mind ideas of infinity, continuity, convergence, and linearity.
