One of the cool exhibits on display for the spectators at Merion last week was a tent explaining the science of golf. If you didn’t make it to the U.S. Open, NBC has produced an ongoing series of videos, available for viewing on the web, that cover topics such as the physics of the swing, friction and spin, water conservation, the evolution of the golf ball and clubs, even how a handicap is calculated. The videos were produced by NBC for the USGA and one of its sponsors, Chevron. Do your homework and maybe you’ll make it to next year’s Open venue—Pinehurst No. 2—as a player. Okay, maybe not: It is science after all, not voodoo.
