GLOBAL HUB on Instagram: "The post features a 15-second video of professional trick-shot artist Steve Markle performing intricate air hockey shots, though captioned as occurring on a “pool table,” highlighting his billiards-honed precision. Markle’s maneuvers rely on geometric reflections, where the puck banks off walls at equal angles of incidence and reflection, akin to light paths in optics. This skill draws from mathematical billiards theory, as studied in dynamical systems, enabling experts
