The Simple Secret To Catching Balls

You do not calculate a ball's trajectory to catch it. Instead, you simply move so your eyes maintain a constant angle toward the ball, keeping it in a fixed line of sight.

This shortcut, known as the gaze heuristic, proves that our brains often ignore complex math in favor of intuitive physical rules. By adjusting your running speed to keep the ball appearing to move in a straight line, your body automatically arrives at the right spot at the right time. You are essentially using a simple visual lock rather than mental trigonometry. It is an elegant example of how humans solve complex problems with surprisingly minimal effort.
