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 ball's 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.

Short Game Tip
The chip and run should be the workhorse of your short game. It is the most reliable shot around the green when you can't putt. I would estimate that at least 95% of my short game shots (from within 20 yards of the edge of the green) are played with a chip and run technique, and the other 5% is made up of putts from off the green, pitches, and bunker shots. Getting the ball on the ground and rolling as soon as possible greatly increases the chances of the ball's behavior being predictable. That is not to say that a chip and run is always very low to the ground; just as low as possible. A chip and run style shot can be played with the most lofted wedge in your bag, in which case some people might refer to the shot as a "pitch and run." In many cases where the average golfer tries to pitch the ball up in the air, the "risk vs. reward" and the uncontrollable nature of a pitch (especially from a marginal lie) make it a poor choice.
Short Game General Rules
--Putt whenever feasible (i.e., IF the ball will roll rather than bounce)
--Chip and run when you can't putt
--Pitch only when you have no choice

The grip most certainly will influence the clubhead, but any type of grip that will keep the wrists from opening or closing the blade is a good grip regardless of how the hands grip the club. Whatever grip is chosen the thumbs should be on top. The thumbs are the feelers and being on top one can feel if the blade is square. Any stroke that holes the ball consistently is a good putting stroke. Regardless of the style of the stroke the putter head should never be taken to the outside of the target line on the backswing.

To achieve a successful golf swing, you must hit the ball with a square club face, and the golf impact indicator will help you do this.

Tips About Beginners Golf training Aid

Imagine there is a line drawn from the toes of your rear foot to the toes of your front foot and continuing on down the fairway. This is the path to which you are aiming your shot. If you're looking for some good golf swing drills to practice this is a good one, place a club or broom stick across the front of your feet and step away to see where you've aimed your shot. Most beginner golfers realize that they weren't aimed where they wanted at all. The best fix for this is to pick a point 120-240 in front of you that is in line with where you want to aim. Square your stance up to that point rather then trying to aim for a spot one hundred or more yards down the fairway. This will drastically improve your accuracy and allow you to concentrate more on hitting the ball well.

Proper Sequence Is Key. There are many elements of impact that must come together to produce consistency, but the key lies in the sequence. From the top of the backswing, the legs and hips must initiate the downswing by moving toward the target, past their original position at address. This creates the proper tilt in the shoulders that allows the right arm to remain flexed at impact, while the left wrist becomes flat. Basically, a proper impact position is the result of a proper sequence of movements.

The target is not always the center of the fairway or green. To setup the next shot the target could be to the left or right of the fairway. Ball flight differs between players. If a player fades his tee shot, the target would be to the left of center of the fairway. If he draws the ball, the target would be right of center.One good point here is to always aim away from trouble on the course whenever possible. If there is trouble on the right, tee on the right side of the teeing area. Do the opposite if the trouble is on the left. In other words,tee the ball on the side the trouble is.
