I had to google why are tennis balls fuzzy so here is the answer.
The fuzz slows down the ball in flight, keeps it from bouncing too high, and lets the racket get a better "grip" on it. A perfectly smooth ball would travel so fast and bounce so high that the game would be unplayable. Also, with a smooth ball, it would be much more difficult for the player to control the direction of the shots. |

I guess this theory could be used for man holes as well.
Why are portholes round. The constant up-and-down motion of a ship puts considerable stress on the ship's skin, or outer covering. If portholes were designed with angles, this stress would tend to concentrate at those points and perhaps crack the skin. With round portholes such stress is evenly distributed around the holes, making it less likely for such cracks to occur. |
