ARE YOU SMARTER THAN A TENNIS UMPIRE?

 

The New York Times suggests computers, not people should call lines. How can Cyclops possibly interpret the other essential rules of tennis.

Two days after the midpoint of the Wimbledon fortnight — following a weekend of a few questionable line calls — the New York Times wrote “At Wimbledon, the Human Eye Keeps Dropping the Ball,” questioning the legitimacy of line judges at Wimbledon. It argued that perhaps Hawk-Eye Live, an electronic line calling system, could have saved several players their matches, including Andy Murray, Bianca Andreescu and Venus Williams, among others. True, the technology of Hawk-Eye, which uses cameras to capture the bounce of every ball from multiple angles analyses the images to depict the ball’s trajectory and impact points, does leave a fairly small margin of error (unless the situation is clay, in which the ball leaves a mark). But how much does the computer really know about the other aspects of line judging — or the rules of tennis for that matter — or how to apply the rules in certain situations.

Test your knowledge in 25 questions of the court, the code violations and tennis’ other strange conditions without an open book, on the first try and with a ninety percent pass rate, and we’ll find you some officials’ swag. Don’t pass, and you’ll get a full-length recording of the irritating computerized and strangely child-like voice calling “out” twenty times for your listening pleasure.
