The Physics of the World Cup: VAR, Smart Balls, and Soccer Aerodynamics (EP 45)
Hosted by Lester Nare and Krishna Choudhary, this episode is our World Cup special — a deep dive into the science, physics, engineering, and data behind the beautiful game.
We start with the offside rule and the controversy around semi-automated VAR. How can a system decide whether a player is onside or offside by only a few inches? Krishna breaks the problem down like an experimental physicist: player speed, ball-contact time, camera frame rate, significant digits, and the error budget behind the line on screen. From there, we get into the actual technology: player tracking, digital twins…
