Why did 404 women and men sit and stood in Paris in the sand this summer? You should see whether the tennis balls that flew back and forth on the tennis courts land inside or outside the field.
The exact number comes from the French Tennis Association FFT, which organizes the French Open, the only of the four Grand Slam tournaments that people use as line judges. The other three organizers rely on the Electronic Line Calling, nickname: Hawk-Eye, which can determine the landing point of the ball with cameras millimeter precisely, now even assisted by AI.
But why does the FFT want to stare on lines instead of machines instead of machines at least next year? Because of the “excellence of the French referee system”, which is “recognized worldwide and […] full satisfaction “.
So it says in the message. And with a view to the mechanized world in which we live, this is a nice message for the places where we can afford it: better 404 people than the next error 404.
