SPORTS: INTRODUCING THE "HAPPY NON-HOOKER"

T. H. Maugh

Two scientists from California have used their technical ingenuity to make a significant improvement in the golf ball. They have invented a ball that resists hooking or slicing.

They used a principle from Newtonian physics that might be called "the spinning dumbbell rule." Two rigidly connected weights tend to spin around only one axis at a time-like a baton.

In this new ball the dimples cover 50% of the surface confined to a band around the equator with the poles smooth and with weight slightly concentrated in the poles.

In tests the "Happy Non-Hooker" achieved more than 90% of the distance of a conventional ball while reducing slicing by 75% to 80%.
