Most modern golf balls have about 300–500 dimples, [29] though there have been balls with more than 1000 dimples. The record holder was a ball with 1,070 dimples—414 larger ones (in four different sizes) and 656 pinhead-sized ones. [citation needed]
The effect occurs at lower Reynolds numbers when the ball is rough (such as a golf ball with dimples) than when it is smooth (such as a table tennis ball). In fluid dynamics , the drag crisis (also known as the Eiffel paradox [ 1 ] ) is a phenomenon in which drag coefficient drops off suddenly as Reynolds number increases.

Golf balls are spherical, usually white (although other colours are allowed), and minutely pock-marked by dimples that decrease aerodynamic drag by increasing air turbulence around the ball in motion, which delays "boundary layer" separation and reduces the drag-inducing "wake" behind the ball, thereby allowing the ball to fly farther. [38]
The heavy side of the golf ball sinks to the bottom, DeChambeau - a physics major - said, and then “we mark the top with a dot to make sure it’s always rolling over itself.” Bryson ...
