A year ago , however , something happened that made me change my mind about math . My dad is an industrial engineer and a math and science genius . He went to college in the days when the calculator was just starting to take the place of the slide rule . Anyway , he and I went to the U.S. Space and Rocket Center in Huntsville .
Where did the writer and his dad go to ?
