Bungee Jumping
While modern bungee jumping has become known and practiced worldwide, what is less understood is the physics behind bungee jumping. Interestingly enough, the extreme sport originated from spiritual rituals of South Pacific natives, who had no idea of the science behind the sport. Modern bungee jumping enthusiasts find much comfort in the idea that someone has worked through the math required to perform a safe jump. So who developed the physics of bungee jumping and how sure are the modern practitioners of the sport that it is relatively safe? Let’s start by taking a look at the origins of the science behind the sport.
Years before the discovery of the land diving natives on Pentecost Island, a British mathematician named Robert Hooke was discovering the physics of bungee jumping. He began working as an assistant to the famous scientist Robert Boyle in 1653. However, it wasn’t until 1660 that he formulated and wrote down Hooke’s Law of Elasticity. In laymen’s terms, Hooke’s law basically tells us how much tension a spring can endure, and the maximum length it will reach. Hooke’s law can be used on any material that is considered linear-elastic, or stretching lengthwise. Oddly enough, rubber is usually considered non-linear, because variations of stress and temperature can have a significant impact on the elasticity of the rubber.
Today, modern practitioners of the physics of bungee jumping don’t have to be as well-versed as Hooke. Depending on the bungee cords used and their ratings, the science has been simplified quite a bit. The commercial proprietor who is offering ‘bungee jumping’ as an extreme sport still has to be on their toes. Cords that are manufactured to meet a well established United States military specification (mil spec) are perhaps the best to use. This is simply because of the rigorous testing that must go in to making sure they meet the mil spec. Most of these cords have a specific weight limit and elongation potential. Using these numbers, along with the length of the jump and the weight of the jumper, the calculations can be made. The length of rope needed, how many strands are needed for the weight, and how much beyond the normal length of the cord the jumper can expect to go.
The physics of bungee jumping has changed some with advances in the material used in bungee cords. Some cords are also ‘pre-streched’ so there is less elasticity and bounce, and a more forceful shock and return from the bottom of the jump position. The problems with some jumpers using cords that were too long are the result of not understanding the physics of bungee jumping. Even though modern bungee cords are weight and elongation rated, some people still fail to take this into account when performing amateur jumps. This is why it is highly recommended that anyone who wants to learn bungee jumping should consult with a professional. This is not a sport that you can learn and practice at home. The physics of bungee jumping have been simplified by 20th century manufacturing standards, resulting in a much safer sport for everyone participating.

There’s a new trend in bungee jumping, but I wouldn’t exactly say that it’s taking the world by storm. So what is this new angle on the ancient sport of bungee jumping? How about naked bungee jumping. OK, so I know you think I’m crazy, but there hundreds, perhaps thousands out there who will swear by this experience. Let’s take a few minutes to look at the possible attraction, as well as the detractors, of this bizarre variation on the sport.First, it is interesting to note that the natives who have performed the ritual that has become bungee jumping for thousands of years wear very little clothing. I’ll admit, it must be a bit different jumping from a make-shift wooden tower using a jungle vine attached to your ankles. This is a far cry from modern bungee jumping. However, these native young men wore nothing more than a flimsy loin cloth on their plunge to please mother earth. So in some primitive, instinctual way, there must be a spiritual attraction of sorts in performing naked bungee jumping. Some people who choose to participate in this variation of the sport have admitted to being extreme naturalists, even nudists. Of course, there are those who complete nude bungee jumping who wouldn’t qualify as nature lovers at all.
A common theme that is seen at the special events held for such display is that of a couple performing a tandem jump. A tandem jump is simply a jump where two people go together, usually tethered together, facing each other. There is obviously some primitive expression of sexuality in this type of event. However, more modern couples are choosing to participate in naked bungee jumping to show their devotion to one another. Taking the plunge can now be applied to more than just marriage! Many couples who share their experience afterward say that there is a definite bonding that takes place. Sharing an adrenaline rush such as the death-defying act of naked bungee jumping is something that will tie them together forever in their eyes.
Another reason many people choose to go ‘full monty’ on the ropes is because it is usually cheaper. Yep, you heard me right. Although the time investment and equipment used by the jump company is the same, the cost is less. Some companies even allow those brave souls who want to go naked bungee jumping to go free of charge. These types of promotional efforts appeal to those who are of a more frugal nature. Some companies that offer naked bungee jumping do so once a year, on a pre-planned date or weekend event. This helps make the event more palpable to the public. Imagine going to an amusement park and seeing people riding the rides naked! It would be a great shock, especially if you did not know that it was planned that way. By scheduling the special jumps for a specific date, the promoters of this type of event avoid that aspect of publicity.It’s growing among the ardent fans of the sport, as well as the newcomers. It seems to have no defining characteristic except that those who perform it are lovers of adventure. So whether you believe in the spirituality of it all or not, naked bungee jumping is here to stay.

“Drive for show, putt for dough” is the lesson we’ve
all seen and learned from watching professional
golfers in every tournament and championship.The masters of golf can drive a ball from here to
eternity, but it all boils down to how many strikes of
the ball it takes to put the ball in the hole. The
long accurate drives don’t amount to anything if
you’re unable to putt accurately.Choosing a putter is important, but using whatever
putter you have consistently is more so. I’ve had the
same putter for fifteen years; I know what it feels
like in my hand, I know its weight and how that plays
into my putts.Putting takes lots of practice. Typically, we drive
the ball eighteen times in a game, but putt at least
double that number. Doesn’t it stand that we should
practice our putting at least twice as much as
driving? If you can’t get to the practice green
regularly, practice on your carpet at home.
Keep in mind that no ball can make it into the hole if
it doesn’t have enough power behind the ball to get
there. Take the time to get down and look at the path
from your ball to the hole; does it slant one way or
the other? Is it uphill or downhill?Stand with your feet spread for balance and line up
the putt. Keep you hands, arms and shoulders
completely still; imagine that you are a “bobble head”
but you move from just below your chest. Keep your
head directly over the ball. Pull your club back; keep
your hands, wrists, arms and shoulders steady-the
movement comes from your chest. Hit the ball,
following it with your club.Learn from each putt and remember the lesson.
Practice, practice, practice!

Get Yourself Online
If you are interested in taking up a new hobby, and you enjoy thrilling, fast paced action, why not consider snowboarding? Increasing in popularity year on year, snowboarding has always been highly fashionable, and is no more accessible than ever, so you really have no excuse for not giving it a go if you are interested. In this article we will look at the equipment you will need, where to get started, and the things to watch out for when snowboarding.First thing’s first - get yourself online. Look around, and find out exactly what snowboarding involves. It is a dangerous game, and highly physically taxing. Additionally, it can be quite expensive, so you need to try to ensure it’s right for you. Next you need to look for a board to get you started, and some clothing for wearing on the slopes. First off, forget about buying a top quality board. You need to start off with something cheap and cheerful, designed for beginners. You can find these easily online, and you may also be able to come across some models in your local extreme sports shop. Alternatively, you could try to pick one up second hand from a friend, or from another snowboarder. You also want to make sure you look cool whilst your out there! Check out some of the highly fashionable snowboarding wear, and kit yourself out from hats, to sunglasses to thick socks - make sure you’re prepared for the elements before you set off.
It is worth looking around to find lessons in your local area. Lessons range in availability, quality and price, although you will often find recommendations or local adverts particularly helpful. Again you could look online for some tips to get you on your way. If you do take lessons, it is important to take on board what the instructor says from both a performance and safety perspective. Additionally, get out there and practice between lessons if you ever want to improve. If you stick at it, and work hard, you will eventually see an improvement, and find the sport significantly more enjoyable also.It is also good to note that snowboarding is a highly dangerous activity and people do get hurt. Before you even think about snowboarding, take some lessons in safety, and make sure you are fully equipped both mentally and physically for avoiding injury to yourself and others. Snowboarding is responsible for many accidents every year, and it is an extreme sport after all - if you’re of a weak disposition, it is perhaps not the best sport for you. Having said that, snowboarding can easily be performed safely with a bit of common sense, and a bit of research, so make sure you’re prepared before you get out there.arnings aside, snowboarding is great fun, if you like this sort of thing. Many people adopt the mantra that you should try everything at least once, and as far as snowboarding is concerned, this is definitely true. Try snowboarding once, and join the legions of followers who enjoy snowboarding at every opportunity. Chances are there are clubs and associations in your local town, so get yourself along and join in with like minded people. Your level of experience doesn’t matter, as long as you go along and participate, you will gain a lot from it, and you will definitely have a good time in the process.

Have you ever considered sky diving? Do you wonder what sky diving would feel like? Do you know much about sky diving? Sky diving definitely looks like, a frightening experience. Just watching people jumping from plans from thousands of feet in the air is enough to send chills down your spine. One would have to wonder whether sky diving is as exciting as people make it out to be or is this activity a total nightmare. For those who are not interested in sky diving or would never even consider it, perhaps to them it seems like a foolish and crazy thing to do. However for thousands of people in the world, the thrill of sky diving keeps sending them back for more.Sky diving is a sport that requires training in safety and technique. Serious sky divers learn all the necessary skills needed for making the jump. However for the person who’s always been fascinated with sky diving but not interested in making it a hobby, there is one method of sky diving that doesn’t require instruction. This form of sky diving is referred to as tandem skydiving. It is considered to be safe, quite easy and very exciting. This sky diving technique allows a person to freefall at very high speeds while being harnessed to an instructor. For the individual who’s always dreamt of jumping from a plan, this type of sky diving is probably best for them.
For people who try tandem skydiving and decide they’d like to take it to another level, perhaps even make it a regular activity, the accelerated freefall technique is likely for them. This form of sky diving requires training and plenty of practice before attempting it on your own. Accelerated freefall sky diving, with proper instruction, can allow a person to freefall on every single jump. To learn accelerated freefall there are various stages of instruction a person must go through. Throughout this learning process an individual learns about stable and balanced body position and relaxation. This is certainly important for sky diving. A trainee is also taught about altitude awareness, pilot chute throw, turning techniques, hover control, radio assisted landing and other necessary lessons for accelerated freefall sky diving. This form of sky diving is believed to have a couple of benefits over other training methods. Accelerated freefall provides an individual plenty of time to practice their sky diving techniques because they are continuously freefalling. It’s also great for instructors because they are able to use hand signals during this training which teaches the individual to change their positioning to provide better results.Contrary to what you might think, sky diving does not make a person feel as if they are falling. Instead when a person jumps, it’s as if they are being supported by a cushion of air. When thinking about sky diving, automatically you may sense a feeling of an upset stomach. However, people say the experience is similar to being in the water, the body is buoyant. Sky diving is an activity that an individual would probably have to experience for themselves in order to actually understand how it feels. Unless you are determined to try sky diving, there is no need to strap on a parachute just yet.

Now let me tell you about some of the greatest places that there are to snow board in the world. I really mean I am going to tell you about the places, that if you are a snow boarder you simply must visit if you want to have experienced the greatest snow boarding that is out there.
Solden in Austria
This amazing resort is about 50 miles away from Innsbruck and a further 20 miles away from Otztal. This amazing place has three killer slopes that have three of the speediest lifts in the world that also have some of the best views that I have ever seen. At least one night in the week the slopes open up to give you a chance to go night boarding in style. There is also a firework display and everything else that you can imagine to make the night a success, you can actually go for a drink in between runs and really enjoy all the aspects of snow boarding whilst drinking at the same time. If you have never been night boarding before this is something that you have to check out.
St Anton in Austria
St Anton has some of the best terrain that I have ever seen and that is one of the reasons that I think this place is up here in the best snow boarding destinations. If you like to free style then this is undoubtedly the place to be doing it. The slopes are not very forgiving and unless you like high speed, high octane fun then you should probably go elsewhere. The slope has amazing amounts of powder and really helps and boarder to accelerate a lot faster than they are used to.
Tignes in France
Tignes is without a doubt the place to go if you want to go snowboarding in France. Tignes was one of the first locations to actually welcome snowboarders whilst other felt that skiing was the only thing that you can do on the slopes. But let me tell you one thing ladies and gentleman. This place is also the top place to learn your trade, with a wide range of training courses for those that want to teach snow boarding for a living. If you are looking for tree runs then this is not the place to hang, but it certainly has a lot of excellent runs that you simply must try.
XCAPE BUILDING SNOWZONE in the UK
This is the best in indoor entertainment that is out their. If you think playing your play station is indoor entertainment then you really have another thing coming folks. You only pay an hourly fee for the time you spend on the slopes and that even includes boot hire and hiring of a board. The fact is that this is such as enclosed area, and there are instructors all over the place watching what you do. When I went I got a lot of helpful feedback from instructors and at their own free will. A very good place to learn.
LAAX in Switzerland
LAAX in Switzerland
This my friends is snow boarding heaven and a must, see and do for everyone. This place is home to some of the biggest snow boarding events in the world, and you never see a pro turn down an opportunity to strut his stuff on these challenging slopes. When an event happens here it really is seen as being cool, as well as whatever else. The top DJs, singers and pop stars all want to come along to associate themselves with whatever is going on. This place has half-pipes galore for those who would rather flip than anything else. The ski lift is also good and for many beginners this is the most enjoyable part of their visit. You will find some challenging slopes as well as other slopes that are tailored for beginners.
