~ It's similarities to Earth give Venus the nickname "Our sister planet".

~ A year on Venus lasts 224.7 earth days.

~ A day on Venus lasts 116.75 earth days (the sidereal day - the time it takes to complete one full rotation - on Venus is 243 days, which is longer than its year!).

I always wondered...
...how golf balls works...


The earliest golf balls were smooth and made of wood. Early in the 17th century, the 'featherie' ball was introduced and was constructed of tightly compacted goose down inside a cowhide casing. Later, tree sap was heated and formed into a ball, which flew truer because of imperfections in the ball. This led golf ball makers toward the distinctive dimples we know today. The 20th century contributed core technology, introducing a solid inside the ball allowing designers to fine tune the length, spin and feel of golf ball characteristics. Today, golf balls have titanium or other metal cores and may be composed of up to four layers.

The diameter of a golf ball cannot be smaller than 1.68 inches. 250 feet per second is the maximum velocity for the ball. Maximum weight of the ball cannot exceed 1.62 ounces. Most golf balls have between 300-450 dimples.

The millisecond-long impact of club and ball determines velocity, launch angle and spin rate. In its flight, the ball will experience drag and lift. The dimples on the ball work in two ways which affect these aerodynamic forces: (1) as the ball moves through the air, the dimples reduce drag by reducing turbulence (pictured), and (2) backspin induced by the angle of the club creates lift which is magnified by the dimples.
