Golf Balls -- The Science Behind The Dimples
by Susan Chiang
The dynamics behind the flight of the golf ball offers a fascinating insight into the physical interworkings of air pressure, turbulence, and aerodynamics.
When golf was first played in Scotland, most players played using clumsy golf apparatus, with the first golf clubs and golf balls made of wood.
In 1618 the 'Featherie' was introduced. It was a golf ball made of feather. This feather golf ball was handcrafted from goose feathers tightly pressed into a horse or cowhide sphere while still wet. After drying, the leather shrank and the feathers expanded, creating a hardened golf ball.
As this type of golf ball was specially handcrafted, it was usually more expensive than golf clubs, so that only a few privileged people could afford to play golf back then.
After the Featherie golf ball came the Guttie golf ball. This type of golf ball was made from the rubber-like sap of the Gutta tree found in the tropics, and was shaped into a sphere when hot and eventually into a golf ball. As it was made of rubber, the Guttie golf ball could be cheaply produced and easily repaired by reheating and reshaping.
Comparing the two types of golf balls, the Featherie golf ball was said to travel farther than the Guttie golf ball because the Guttie golf balls smooth surface prevented it from covering more distance.
With this discovery, the developers of golf balls came up with the 'dimpled' golf balls that are so predominant in modern golf nowadays.
The dimples on the golf balls help reduce the aerodynamic drag. Aerodynamic drag normally affects smooth golf balls and slows them down, because when they sail through the air, they leave a pocket of low-pressure air in its stir thus creating a drag.
By applying dimples to the golf ball surface, the pressure differential goes down and the drag force is reduced. These dimples create turbulence in the air surrounding the golf ball, which, in turn, forces the air to clasp the golf ball more closely. By doing so, the air trails the warp created by the golf ball towards the back instead of flowing past it. This results in a smaller wake and lesser drag.
Dimples were first added onto golf ball surfaces back during the gutta percha phase. Coburn Haskell introduced the one-piece rubber cored golf ball encased in a gutta percha sphere. Then in 1905 William Taylor applied the dimple pattern to a Haskell golf ball, thus giving rise to the modern golf ball as we know it today.
After its beginning, dimpled golf balls were officially used in every golf tournament. In 1921, the golf ball took its current form with standard size and weight. Nowadays there is a wide range of golf balls to fit every style, game and condition, with some golf balls offering control, and other golf balls offering distance.
Though a common sight nowadays, the dimpled golf ball is not just a mere element of the sports arena; it is a showcase of physics at work.

Prime Movers
Notice how my upper left arm and chest are connected. It's this connection that initiates the backswing and encourages the club to be moved by the pivot of the body and not the hands and arms moving independently. In addition to the left arm and chest, movement of the shoulders and back should also contribute to the finish of a powerfully coiled backswing. Don't ever begin your backswing by lifting your arms or rolling your wrists by themselves.

When you want to get some extra distance out of your drives, it�s natural to think that your right or dominant hand (for right-handed golfers) should supply the power. In reality, however, maximum power is a result of a left-hand lead.

Take it easy! Many golfers hibernate for two or three months during the winter. Due to inactivity their muscles and tendons used in the golf swing lose much their tone and elasticity, so once you finally get to play make sure you stretch and loosen up before you tee off. Golfers with a history of back problems should be particularly cautious, otherwise they may ruin the new season before it even begins.

What's important to note with head movement, just as in the weight shift, is that it's not something you should think of. It is simply just a reaction to what you do with the golf club. When a golfer starts thinking of shifting their head a little bit here, and a little bit there, there is big time trouble awaiting.

The Ping Golf Club: An Overview
By Lee MacRae
For a golfer, one of the most important things that he should examine is his golf club because according to experts, it is one of the main reasons why they do not hit the ball. This is the exact reason why the Ping golf club was born.
Karsten Solheim was the one who invented the ping golf club with different intentions. The story has it that Karsten was practicing golf but he could not hit the ball so he started to practice up to the time that he began to design and experiment his very own putter so that he could play better through it. He thought of designing his own putter without a figment of a though that it would be known worldwide. By the year 1959, his putter experiments had evolved into 1A design. While deciding for the name, he heard the sound of his putter and declared proudly to his wife that he would name the putter from its sound, hence the name �ping�. At that same year, Sports Illustrated published an article in their August issue regarding the ping golf club dubbing it as a musical putter.
This was the beginning of success for the ping golf club. At present, the Ping golf club is manufactured in Phoenix, Arizona by Karsten Manufacturing Corporation. There are more than 400 patents registered for the ping golf club and each of these designs are all innovative and very original designs that are suited for each and every golfer. Here are some of their key patents and products:
In the year 1962, the Heel-toe weighting type of ping golf club was granted patent. This design was the one that revolutionalized other modern designs and golf clubs that are manufactured in the market today. In the year 1969, another type of ping golf club was introduced which was the perimeter-weighted, investment-cast iron. The reason for this type of ping golf club is that the perimeter weighting is able to increase the moment of inertia thus when a ball is not struck squarely on the face it makes the club more forgiving. Another innovative movement for the ping golf club was the application of investment casting in the manufacture of the K Series Irons. This is not really a new technology in fact; the old name for it is the lost-wax process. The purpose of this type of method is to ensure precise detail and consistency to all of the parts of the ping golf club. Another type of patent for the Ping golf club is the Cushin Selective Filtering Insert. This is a patented invention which screens out and disperses the unwanted frequencies that can harmfully affect muscle, bone, and connective tissue. Through this invention, the golfer receives less vibration with greater feel on each shot.
The reason why the ping golf club is popular and widely used is because of its innovative, ever-changing yet reliable design. These designs are what people, particularly golfers, recognize about ping golf club. lost one of your ping golf clubs? Do not worry because serial numbers are here to save you! In every ping golf club, there are serial numbers which are etched on every PING iron. If ever there is a need to replace one club, the company has the exact specs at the time of manufacturing on file and could actually build a new club to match your set.

Beginning with this idea in mind, you will see that when honing your golf skills it makes sense to start with smaller swings, then build up to the full swing. This is the reason why a person just learning the sport will learn and teach the body the correct motions iin developing an accurate and powerful swing by starting with the short swing. Trying to learn the full swing first makes it much more difficult to learn the correct muscle coordination that the full swing requires.

An offset shaft or hosel on a putter is generally a good thing for a recreational golfer (and many pros, too). Offset helps the golfer line up with his or her forward eye over the ball, and with a good line of sight. Offset also helps keep the hands ahead of the ball when the putt is struck, which is a putting fundamental. Many putt great without offset, so it's one more thing that comes down to feel.

To learn how variations of the grip affect ball flight. Experiment with slight variations of your grip. Observe how the changes affect the flight of the ball. A weak grip encourages a slice or fade. A strong grip encourages a hook or a draw. The V.s formed by the index finger and thumbs on both hands should point between the chin and right shoulder.

Assuming the texture of the sand is similar, and the ball is not plugged, the technique for hitting out of a greenside bunker remains the same for shots up to 30 yards (27m). The key to making this shot is hitting the sand about 1 to 2 inches behind the ball, throwing the sand forward with the ball. For longer shots the only thing that changes is the swing's length. Rhythm and tempo remain the same.
