Since then, I've been trying to replicate this feat in my position as striker for the amateur team "Beer Fit" in San Francisco, though without any success so far. This is what prompted me to turn this into a video game written in Go for my Programming Snapshot column.

The underlying physics for the chip shot [1] in soccer is known as "projectile motion," and it's described in any good undergrad physics book. I happen to know this exactly because during my electrical engineering studies I sweated my way through many an exam in the murderous "Technical Mechanics" course. And even many, many years later, holding a totally yellowed degree certificate in my trembling hands, I only needed a short refresher to derive the formulas for the ball position as a function of the starting point, the angle and the velocity of the launch, and the elapsed time.
