The average depth of a dimple is about 0.010 inches.
The lift and drag forces on a golf ball are very sensitive to dimple depth.
A change of 0.001 inch in depth can produce a radical change to the ball's trajectory and the overall distance a ball can fly.
Dimples are traditionally shaped spherical.
Some golf ball manufacturers use hexagon shaped dimples.
The first golf balls from the 14th Century were made out of wood, specifically beech.
In the 1800s, Robert Adams Paterson made the first molded ball out of the sap from a sapodilla tree, native to Malaysia.
On 11th April 1899, the American businessman and inventor Coburn Haskell got a patent from the United States Patent Office for the rubber-wound golf ball.
This ball is widely regarded as the first modern golf ball. It was made of a solid rubber-wound core that was covered by guttapercha.
