who invented the dimples on a golf ball
Golf ball In 1848, the Rev. Dr. Robert Adams Paterson (sometimes spelled Patterson) invented the gutta-percha ball (or guttie, gutty).[4][5] The guttie was made from dried sap of the Malaysian sapodilla tree. The sap had a rubber-like feel and could be made round by heating and shaping it in a round mold. Because gutties were cheaper to produce, could be re-formed if they became out-of-round or damaged, and had improved aerodynamic qualities, they soon became the preferred ball for use.[6][7] Accidentally, it was discovered that nicks in the guttie from normal use actually provided a ball with a more consistent ball flight than a guttie with a perfectly smooth surface. Thus, makers began intentionally making indentations into the surface of new balls using either a knife or hammer and chisel, giving the guttie a textured surface. Many patterns were tried and used. These new gutties, with protruding nubs left by carving patterned paths across the ball's surface, became known as "brambles" due to their resemblance to bramble fruit.
Times Square Ball The ball's design has been updated over the years to reflect improvements in lighting technology; the ball was initially constructed from wood and iron, and lit with 100 incandescent light bulbs. The current incarnation, designed by Harlem-based architectural lighting firm Focus Lighting,[1] features a computerized LED lighting system and an outer surface consisting of triangular crystal panels. These panels are produced by Waterford Crystal, and contain inscriptions representing a yearly theme. Since 2009, the current ball has been displayed atop One Times Square year-round, while the original, smaller version of the current ball that was used in 2008 has been on display inside the Times Square visitor's center.
