The weather was nearly perfect at the U.S. Open but it was necessary to apply a good dose of homosalate and methoxycinnamate to provide protection against the ultraviolet A (UVA) and B (UVB) sun rays. I don’t know much about tennis but being in Flushing, New York at the USTA National Tennis Center watching Andy Roddick and Juan Carlos Ferrero was an incredible experience. The skill and stamina of these two young men was awesome. I am unqualified to comment on the key factors in the game results, but it appeared to me that the twenty-three aces by Andy Roddick had to be key. His serves came across the net like missiles — some exceeding 140 mph. The IBM Radar Gun recorded the speed of every serve and instantaneously fed the result to a digital display. Radar heads were positioned at each end of the court, facing down the center line. As the server prepared to hit, the radar was activated and then picked up the ball about three feet beyond the server’s racquet, where it travels fastest. The data then went to an IBM ThinkPad that calculated the speed, and sent the result to the digital display on court. This was just one small part of a wide range of technology which IBM utilized behind the scenes.
