Glass walls turn tennis into a game of billiards

In 1969, Mexican businessman Enrique Corcuera accidentally invented a new sport because his home lacked the space for a full-sized tennis court. By surrounding a smaller plot with walls, he created padel, a game where the geometry of the court is as important as the swing of the arm. Unlike tennis, where a ball hit past you is a lost point, padel players use the glass walls to keep the rally alive. They calculate vector reflections in real-time, much like a billiards player lining up a bank shot.
