The golfing community has splintered into two deeply combative factions: the old-school players who believe in feel, artistry, and imagination, and the technical-minded who want to remake the game around data. Traveling from historic St. Andrews to manicured Augusta, Brett Cyrgalis takes us inside the culture war, profiling the golfers clad in full-body sensors that target weaknesses in their biomechanics, those who take part in mental exercises designed to test their psychological resilience, and coaches who purge golfers of all technical information so they can tap into the power of intuitive physical learning.
