Beginner Golf Lessons - Thumbs Up - The Hitchhiker Move!
We all know the drill - go from the hitchhiker position (thumb up) in the backswing, swing through the ball and uncock the wrists, and then continue on to the hitchhiker position (thumb up again) in the follow through. this is a favorite tip from davis love III.
Here some high school geometry is necessary - BUT - don't worry. No homework here. I will do the math.
The circumference of a circle (your golf swing) is the distance around the outside of a circle. this is defined in the formula - 2pr , where p (pi) is the value 3 (remember, we are keeping it simple) and r is the radius of the circle which we assume to be approximately the length of your arm - 1 meter (or 1 yard if you are in the USA).
this means the total distance around the circle is 2 x 3 (the p in the formula) x 1 meter = 6 meters in total.
So if the radius (your arm) turns through a full circle in only 0.2 seconds, the clubhead speed is 6 meters / 0.2 seconds = 30 meters per second. So far so good.
Now lets put a golf club at the end of your radius (your arm). And lets use the same values as before. The only difference is that the total radius is not only the length of your arm (assumed to be 1 meter) but now the length of the arm plus the length of the golf club, or 2 meters (I am assuming a golf club length of 1 meter and your arm length of 1 meter.) So, 2 x 3 (the p in the formula) x 2 meters = 12 meters in total distance around the circle. And again, we assume a turning time of 0.2 seconds. The clubhead speed is 12 meters / 0.2 seconds = 60 meters per second!!!!
To say this in other words, by starting off with a radius of only 1 meter (hand COCKED) and then EXTENDING the radius out (UNCOCKING the hands), the clubhead speed is DOUBLED without any changing the the timing of your body turn!
In physics, this is called a surface effect. The same rotation speed with generate increased clubhead speeds at increasing lengths of the radius. Yes - for the purists - there are some subtile points I didn't discuss here. There will be a slight slowdown in the rate of turning to the movement of the center of momentum farther away from the center. Nonetheless, learn the general principle - Cock / uncock can double your clubhead speed. For this series of how to swing the golf club lessons, it is important , it is important to understand that the cock / uncock of the hitchhiker move is essential to every good golf swing.

Hard Water Problems in the UK
Calcite, the main cause of scale, is the most common form of calcium carbonate and occurs naturally as a natural ingredient of chalk, limestone and marble. Water passing over and permeating through such rocks dissolves calcite when this water subsequently flows through a water system the calcite precipitates out to form a very hard scale on surfaces.When hard water is heated, or evaporation takes place, the problems are exacerbated. Calcite forms ever growing layers of rock-like deposits until eventually pipes, jets and equipment become totally blocked. The problem increases as the water gets hotter. Water containing 145 ppm of calcite, flowing at 3.5 litres per minute, produces in one year 4.8 kilograms of scale at 60C. At 80C this rises dramatically to a massive 29.9 kilograms! scale wastes both energy and financial resources just one eighth of an inch of scale reduces heating efficiency by 25%. It is also very expensive to remove, de-scaling pipes and boilers alone costs British industry over 800M each year.
hard water substantially increases energy consumption, necessitates equipment downtime for cleaning and results in the early renewal of capital equipment. Executives involved in running a business, local government department or institution are under increasing pressure to cut costs and become more efficient. However this must be carried out with due regard to increasing environmental legislation.
Scalewatcher is a unique, efficient, energy-saving device better than the water softener or a magnet. It is designed to eliminate the problems of hard water, whilst retaining the natural benefits. This is achieved by changing the size of the particles of precipitated compounds, by aiding the ability of crystals to form their shape, and by altering the solubility of compounds within liquid. Scalewatcher takes the process of induced ionisation to its ultimate stage. The principles of Magnetohydrodynamics (MHD) are applied by passing scalewatcher's patented signal through a coil wrapped around the pipe to be treated. The signal consists of a frequency modulated (FM) wave form within the audio frequency (AF) bandwidth. This inaudible sonic frequency signal sets up a dynamic field around and through the coil, pipe and water, and modifies the calcium carbonate crystal nuclei. The nuclei upon which the crystals start growing are minute in size and have charged surfaces in their natural condition within the water. When they pass through the field, these naturally charged nuclei encounter considerable forces as the field interacts with them. The field acts at the surfaces of the nuclei and modifies the nature of the electrical charges and this ionisation effect thus alters the growth rate and pattern of the crystals in general and on specific planes.
The principle of magnetic water treatment is not new. The first patent was granted around 1900. Scalewatcher takes this knowledge into the 21st century. The electronic device treats the water by inducing magnetic AND electric fields with a continuous changing frequency. This forces the dissolved minerals such as Calcium and Magnesium to crystallize in the water before the ions settle (hard scale) at walls of piping, bathroom or heating elements of dishwasher and washing machine. This action stops any further build up of hard scale by preventing the settlement of dissolved mineral ions on whatever surface.
Advances in micro-electronics have enabled scalewatcher to produce a system which is so compact that it can be installed in small or normally inexcessable spaces. It is ideal for commercial applications such as laundries, hotels, garages, dentists, correctional centers, restaurants and bakeries. Easily fitted and requiring no plumbing, chemicals or maintenance. Scalewatcher benefits include : increased life for capital equipment, lower energy bills, short term payback, reduced mechanical damage and failure environmentally friendly and hazard free.
The capability of the water to dissolve minerals will also be increased and this is the reason why hard scale layers will be softened, will slowly enter into the water stream, and will disappear down the drain.

Reasons To Own A Boat
Reasons to own a boat:
There are many advantages to owning a boat. Relaxation, time spent with friends and family, and enjoying nature are only a few reasons why owning a boat is so wonderful.

The kids as well as yourself can enjoy tubing, skiing, fishing, swimming or just cruising along on the calm waters. You will enjoy each others company, laugh, talk, and make memories that will last a lifetime.
Endless waters:
When you are on your boat, there is always somewhere new to go. With 2/3 of the planet covered with water, there is bound to be a river, lake, bay, or ocean that you havent explored. If you think that you dont live in an area where you will use a boat often enough, think again. Most people live within an hour of a navigable body of water. So look up your local marina, and find out where the closest body of water is to you. If it is a small river, see where it leads to. If may be a 20 minute boat ride to a lake you have never been to.
fun and stress relieving:
After working you tail off all week long, you deserve some recreational leisure time. Boating has proven to relieve stress and tension. When you are floating away from the shore, it feels as if you are floating away from your worries and troubles. They are not welcome out on the peaceful water. With endless activities and opportunities that boating has to offer, it can be so much fun. Once you decide what you will be using your new boat for, choose the type of boat that is right for you.
affordable recreation:
Many people think that to be a boat owner you need to be raking in the big bucks. That isnt true. You can finance a boat for around $200 a month. You can save that if you give up going out to dinner a few times a month. Owning a boat can be affordable if you budget your money. There are many money saving tips for boat owners. In the long run, owning a boat will save you money. Think of how much you spend on family vacations. If you own a boat, you can go anywhere that the water will take you. If you have a cabin and bathroom facilities, a weekend trip to somewhere new is always exciting for the family. Now you dont have to pay for a hotel, and you can bring your own food.
Now that you have decided that you cant go another summer without a boat, visit SellUrBoat.com to search for your new boat. It wont be long before you are watching the sun set over the lake that you and your family just spent the day on.
