Digging into dimples can be beneficial, because once you know what to look for, you can buy a ball better tailored to your game. A dimple-less ball would come off the clubface low and fly erratically, falling rapidly from the sky after no more than 150 yards out. Golfers discovered that the nicks and cuts made in the ball from hacked shots actually caused it to fly farther and straighter. In 1908, William Taylor inverted those bumps into symmetrical depressions, thus inventing the modern dimple. Air moves evenly around the smooth ball and creates a large suction at the back, which holds the ball up.
Dimples make smooth air turbulent.
The thinner that boundary layer, the lower the drag, and the farther the ball travels. Dimples have the same purpose as wings on an airplane, which are designed to make the boundary layer an ideal thickness to help keep the plane moving. While a ball's spin actually creates its lift, dimples can increase lift and affect its amount and direction, particularly at lower speeds. Stitches rough up the surface air and enhance the baseball's lift. Settling Differences Dimples come in numerous sizes and shapes.
