摘要

"Featheries", a name given to the golf balls of olden days which made of leather and were stuffed with wet goose feathers. Later, the design evolved and balls began to be made of a gum from the sapodilla tree, heated to form a sphere and became to be known as gutta-percha. Smooth objects offer less resistance to the air flowing around. This, being a common notion for a very long time, the balls designed were very smooth. Over the time, many golfers noticed that old, scratched, and dented golf balls covered a longer trajectory range as compared to a new smoother ball. With dimples, a golf ball travels about twice as far as a smooth ball. This accidentally marked the invention of dimples on a golf ball. By the year 1930, dimpled golf balls were common in practice.
