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.

Microsofts Xbox 360 vs. The Sonys Playstation 3

Microsoft has tried to catch up with some of the titans of the gaming world, such as Sony with the release of the xbox 360. The xbox 360 offers many new features that players will love:

Free limited subscription to online gaming - This allows players who have not been participating in online gaming a chance to see what is available at no charge. All xbox 360s come with Live-aware - This means you can get a friend invite or see who is online and what they are playing from your xbox 360. The button in the middle of the controller makes all this very easy.

It offers great media features including listening to music while you play games, the ability to create custom playlists and your own custom soundtracks, the ability to rip songs from original CDs to your xbox 360 and stream music from your MP3 player to your xbox 360. You can also create slideshows of photos to share with friends and family. Xbox 360 has a wireless controller. No more tripping over the wires, although it can support two wired controllers through USB ports in the front. The game console is not only great for gamers, but developers as well. It is a powerful machine with an unprecedented amount of RAM - a feature added on the request of developers.

But, xbox 360 still has some problems that need to be worked out:

Their Japanese third party support is lacking - While some Japanese developers offer software for the Xbox, it is small in number when compared to what the same developers offer for Playstation. While the controller is wireless, it eats batteries rather quickly. Standard alkaline batteries only last about thirty hours, so if you buy xbox 360, invest in rechargeable batteries to save yourself some money in the end. When they were set up in WalMart stores before days before the launch, many suffered what is known as the xbox "360 screen of death," an error screen. The xbox 360 had also had some problems with overheating. Some report the xbox 360 system as being very noisy when playing an xbox 360 disc.

Many people are eagerly awaiting the release of Playstation 3, which may occur as soon as November of this year. It has been said that the Playstation 3 has an outward feel (which allows it to stand vertically or horizontally on its own), as opposed to the xbox 360's inward feel. It is a much larger console than the Playstation 2 and closer to the original size of the xbox. Game discs slide into the console like CDs slide into a car player.

Here are a few attractive features of the Playstation 3:

It is always on, so you can access your Playstation 3 from anywhere as long as you have an Internet connection. With a Playstation Portable, you can connect to your Playstation 3 and transfer media such as music and movies. The Playstation 3 appears to be much more powerful than that xbox 360, Ninetindo Revolution, and Playstation 2. Initial reports say it will be twice as fast as the xbox 360. Developers and publishers of over 230 games have announced titles for Playstation 3 games.

Here are a few reported cons and problems with the Playstation 360:

Comes with only 256 MB, less than the 512 MB the xbox 360 will come with. Their Playstation Network Platform (the online service) is still in development and may not be ready by the time Playstation 3 is released.

The launch of the Playstation 3 has already been delayed due to disk problems.

Both the xbox 360 and Playstation 3 are incredible gaming consoles. It seems that although the xbox 360 came out first, the best bet is still the Playstation 3. The strongest point of the xbox 360 is its online functionality, but Sony may be working on something similar to xbox Live right now. However, Microsoft is closing the gap with xbox 360 and probably will eventually catch up with Sony in gaming consoles. For some users, it may come down to something as simple as which one is more compatible with the games they already own.

Sunroom Enclosures Styles

Sunroom enclosures are visually appealing due to their unmatched style and design. There are four different kinds of enclosures that you can choose from conservatory, curved, cathedral, and straight. Finding the right design for you and your home is very important. Then you are ready to choose your materials, color, and more.

Sunroom enclosures are not made all of the same. The different designs and styles give you an option to determine which one will look best with your homes design and style. Straight enclosures work best if you are enclosing your patio. They are normally constructed of aluminum on the inside and outside and they may have wooden beams that make up the ceiling. There are a wide range of different ways that a Straight sunroom enclosure can be built. Solid or glass roofs are one option that you will have, as well as aluminum or wooden framing. If you want your enclosure to mess with your house that has vinyl siding, then you can even have the enclosure vinyl sided if you so choose. The options and designs are endless.

Curved Eave sunroom enclosures feature a more symmetrical look that gives added visual appeal. One side of the enclosures wall curves up to form the ceiling and roof. Glass that has a special coating is used to help make the room more energy efficient.

A Cathedral enclosure has a vaulted or sloped roof with a beam that runs down the center. Many different materials are commonly used, including aluminum. The aluminum makes up the outside and inside walls with a roof that is insulated to help make the entire room more able to handle the different weather situations. There are big ranges of different windows to choose from for your sunroom, including windows that can be raised and lowered or fixed windows. It is entirely up to you. Doors are an important part of your room and you can choose to use French Doors or sliding doors, whichever you prefer.

Conservatory enclosures feature glass panels that make up the roof that come together at a bean in the center. This is the most light-filled of the sunroom choices. There are many different styles that you can find in this style, including the georgia, Mediterranean, Pavilion, Victorian, and Edwardian. These are made to be energy efficient with the glass choices and the thermal panels. You will also be able to add details like finials, molding, and windows.

Choosing the design of your sunroom enclosure will take you some time and thought, but you will be amazed at the extra floor space and the added value that it can add to your home.
