In the golf ball design world of air pressure, turbulence, and aerodynamics, surface structurestructure of the surface is a critical design consideration. There are several historical events that have contributed the design and make-up of the golf ball. Over a period of hundreds of years, a better design and composition of the golf ball has been achieved, based on scientific understanding . The humble golf ball is a good example of the development of the history of aeronautical engineering.

When the game of golf began on the eastern coast of Scotland, most players used antiquated apparatus in order to play golf which was a more disorganized and less formal than it is today. In these early days, the first golf clubs and golf balls are made of wood.

feather golf ball was first introduced and made popular. This type of the golf ball gained the nickname of the “Featherie”. This feather golf ball was a handcraftedhand made golf ball that comprised of goose feathers securely pressed into a horse or cowhide outer casing. The whole process was carried out while the ball was still wet. As the ball dried out, the the out skin would shrink and the feathers expanded to form a hardened golf ball.

Because these types of golf balls were specially handcrafted, they usually cost more than the golf clubs. As a result, only only people with money could afford to play the game of golf at this time.

After the ‘Featherie’ the next version , to gain in popularity was the Guttie golf ball. This ancient type of golf ball was made from the rubber like sap from the Gutta Percha tree which comes from the tropics. These Guttie balls could be easily formed into a sphere when hot. When they cooled, they kept their shape and could then be used as a golf ball. With its rubber nature, Guttie balls could be cheaply reproduced and could be easily repaired by reheating and re-moulding.

In a comparison between the two earliest forms of golf balls, the feather golf ball was known to travel cover more ground than the rubber Guttie. The reason for the different distances was eventually confirmed as being due to the difference in surfaces. The smooth surface of the Guttie limits the ability of the golf ball to travel over greater distance.

With this scientific understanding, the developers of golf balls eventually came up with balls with the “dimples” that are associated with modern golf balls in use today.

Dimples are put onto golf balls so as to minimise the aerodynamic drag, which acts on the ball and is increased if it were totally smooth. The reason for this is because smooth balls, when sailing through the air, create a huge pocket of low-pressure air in its wake therefore producing drag. The drag acts as an anchor and the ball reduces in speed.

Alternatively, by placing dimples on golf balls, the pressure differential gets lowered and the drag is made less. These dimples create turbulence in the air surrounding the golf ball. This, in turn, forces the air to cling to the golf ball more closely. By doing so, the air flows in to the wake created by the ball instead of travelling past it. This results in a smaller wake and less drag. Consequently the ball travels a longer distance.

Dimples also help players to put backspin on a shot so making the golf ball break off on the putting green.

The concept of placing dimples on golf balls can be traced back to the Gutta Percha phase of development. It was Coburn Haskell who came up with the one-piece rubber cored ball encased in a Gutta Percha cover. It was during this time that players first observed how their shots became more and more predictable the more they played with the same ball. They noticed that the more the balls became scuffed the more precisely and further they could hit it.

When William Taylor applied the dimple pattern to a Haskell ball in 1905, golf balls finally took on their current shape. So the dimples came into being. From then on, dimpled golf balls were officially part of every golf competition. In 1921, the dimpled golf balls took on a standard size and weight.

Today, there is a large choice of golf balls to fit different golf games and conditions. Some golf balls offer greater control, while some others offer greater distance. However else these golf balls vary, they all have one thing in common and that is the dimple. Golf balls are not just items of golf equipment; they are a paradigm of a physics concept!

Do you want to start your own scrapbook? You’ve heard all about it on TV shows, read it in magazines, and your friends are already on their way to creating their own personal creations. So what exactly is it and how do you get started?

First of all, you need to understand that a scrapbook is not like a photo album or a diary, where you can put items arranged in chronological order. It’s more like a collection of things that represent the ‘non-eventual’ aspects of your life, like dreams, goals, relationships, etc. A scrapbook helps you record the smaller but nonetheless important things in your life that otherwise wouldn’t be included in an album.

Before getting started on a scrapbook, there are a few things to consider. Ask yourself, what kind of scrapbook do you want to make? Should you make one that follows important events in your life? Or will it be focused on a specific idea or theme? For instance, even if you have hundreds of family photos stored over the years, you might not want to include every one of them in your book. Why not create one instead for all the places you’ve gone to? Remember also that writing down your thoughts, memories, and feelings is as important as the pictures that go with them, perhaps even more. Pictures tell only half of the story; without the narration that portrays the emotions and memories behind every image, their real meaning could be lost. The words you write down will also serve as a guide to more accurately portray who you really are when read by later generations.

You don’t have to spend a lot of time working on your scrapbooks. I know people who complain that they would like to start scrapbooking, but they feel that it would demand a lot of their time. Well, they’re completely wrong. Scrapbooking can be enjoyed whether you spend 5 hours on it every day or 1 hour a week; it doesn’t matter at all! You don’t have to spend a lot of time to enjoy this hobby. Forget about the complex decorations. Don’t get caught up in the decorations and the artwork that you may see in other people’s scrapbooks. The most important elements of any scrapbook are the pictures and the stories behind them. I know several people who worry about the beautiful artwork that they see on other scrapbooks. They fail to truly experience the enjoyment that this hobby is supposed to be all about.

A lot of information can be found on the Internet about scrapbooking. You can also find great scrapbook stores for everything you’ll ever need. If you feel like you don’t have the commitment or the passion to indulge in scrapbooking, stop fussing about it. This is a hobby, not a job. It can be a lifelong pursuit, or just a vehicle to capture all the things that make up the real you.

Cat owners have a natural tendency to think of their pets as part of the family, which they are. Still, it’s critical to remember that cats and humans have some very basic differences. A cat’s behavior cannot be compared to a child’s. Remembering that cats have different instincts than humans will help immensely with cat control, and if you forget this you’re likely to end up “herding cats.”

Cats are pure carnivores. Cats behavior is based on its wild nature, which even extends to the way they play and eat. People have a tendency to view cats in human terms and expect them to act like people when, in reality all they want to do is act like cats. Don’t expect a cat to act any differently than nature intended and you won’t be disappointed.

Cats do not respond at all well to “negative reinforcement.” With some animals it works, but not cats. A cat considers it an attack, defends against it, and becomes even more hostile and bad-tempered. “Positive reinforcement” is best, but even “No!” and removing the cat from the problem works better than trying to whack a cat.

Sometimes cats act a little crazy, but a lot of these behaviors come from their instincts. When they spray urine, they are marking their territory and protecting their breeding group. Of course, people do not appreciate such behaviors. Training can work, but if you are not planning on breeding your cat the best choice is neutering.

Your cat vet has many products available for your kitty to use for scratching. It is essential that cats maintain the health of their claws by keeping them sharp and trimmed which helps them catch prey in the wild. In the home, they should be discouraged from scratching furniture and other items in the house. This is achieved by supplying appropriate scratching substitutes like toys, boxes and posts.

Cats also like to stalk prey and toy with them after capture, so toys that are safe to bite and chew on often treated with catnip help dispel this energy. If your cat goes outdoors, sooner or later it will probably bring you the “gift” of a fresh kill. You don’t need to praise the cat, but this is actually a mark of respect no matter how disgusting and the cat should not be punished for following an instinct. Even indoor cats will sometime award you a bug or mouse.

To be a responsible cat owner means researching feline behavior. The cat that is always underfoot isn’t trying to trip you, she’s showing affection. If little Fluffy hisses at you when you get too close to his food, it’s because he is as protective of his meal as any lion in the wild. Learning what your cat’s normal instincts are will go a long way towards making your home a happier, safer one”"for you AND your pets.

Domestic kitties need to be trained how to scratch in more appropriate places than on your furniture. Your cat vet will be able to help you choose appropriate scratching boxes, posts, and toys for your pet.

In order to curb or avoid aggressive cat behavior in your cat, you must have a firm understanding of your feline friend. Your cat is more than likely a content and sociable enough creature but even though it may seem perfect, there will more than likely come a time when your cat is not as well behaved as it usually is.

Before you try to adjust the behavior of your cat, remember a few simple things. Keep some perspective in mind. Your cat doesn’t care about its own behavior, since it will act as it feels natural to do so. Also, physically disciplining a cat due to problem behavior will never help in the long run.

Problems with aggressive cat behavior may involve destroying furniture, using the bathroom out of the litter box, fighting, and even attacking the owner. When making a solution to these problems it is vital to change the behavior of the cat with non-aggressive means, so the wrongdoing is associated to the act instead of you.

When your cat scratches the furniture, it is not willfully trying to destroy it or make you angry, so you shouldn’t get angry in return. Instead, purchase a scratching post and praise the cat whenever it uses it. Cats do respond to praise, so the cat will learn to use the post instead. If the cat still tries to use your furniture instead, simply remove it and put it near the post. It will get the idea eventually.

One particularly frustrating aggressive cat behavior is fighting with another cat. Cats are frequently territorial when more than one cat is living in the same house. They also are born with an instinct to hunt and stalk. Another cat in the home or your shoestrings creates a good source for prey. The best solution for this problem is to make sure the cats each have their own litter box and food bowl.

Cats have mood swings just like we do. Aggressive felines often take these mood swings and expand them into bigger cat problems. Feline illness also can be the root of aggressive cat behavior, since the cat’s natural reaction is to defend itself. Make sure to get to know your cat’s particular moods so that you can read their behavior and act accordingly.

In order to curb or avoid aggressive cat behavior, you must have a firm understanding of your feline friend. Your cat will act as it feels natural to do so. Also, physically disciplining a cat due to problem behavior will never help in the long run. It is necessary to change the cat’s behavior by using non-aggressive methods. Remonstration must be associated with the cat, not you. Purchase a scratching post and praise the cat whenever it uses it. Changes in mood can cause docile cats to become aggressive cats. Illness can also cause temporary cat problems that manifest as aggression.

Perhaps the most common annoyance with domestic cats, accounting for four out of every ten complaints about house soiling, occurs when a cat puts its back to an object and releases a pungent spray. This is called “cat spraying,” and is a cat’s way of marking its territory. “Cat spraying” occurs mostly in un-neutered male cats (toms), but some female cats are also known to perform this activity when in heat.

Cats can spray for multiple reasons. Territorial disputes can cause them to spray. Another cat in heat can cause them to spray. The stress of fighting with another cat can cause them to spray. Normally cats mark their territory to reduce conflicts with other cats. Most of the time they spray outside, but if there are conflicts inside they will do it there.

When the cat sprays an object, it releases a foul smelling odor akin to ammonia. Removing the smell quickly and completely is important because the smell will encourage the cat to spray again. To remove the smell, clean the object thoroughly with an enzymatic cleanser specially designed to remove odors. Avoid cleansers with ammonia because it smells like the spray itself.

How can you stop this annoying habit or can it even be stopped? Neutering a male cat will greatly reduce the occurrence of cat spraying. A cat whisperer or someone trained in cat psychology can help resolve or minimize the problem by identifying conflicts within the home. You can rearrange furniture or place objects around a particular location that a cat is spraying to make it a less appealing site. Until conflicts are resolved with neighborhood cats, you might have to keep your cat indoors to prevent spraying outside of the home.

Don’t ever try to punish your cat by bringing him into the area and hitting him. This will lead your cat to be fearful of you. Your cat will probably have increased stress, which can in turn make your cat spraying problem worse.

Even if you take all the necessary precautions, cat spraying can be extremely hard to completely eliminate, but you can learn to minimize it. It’s just part and parcel of living and caring for your feline friend.

Cats spray for a variety of reasons. They spray during territorial disputes, when they are aware of another cat in heat, when stressed and often after fights with other cats. When the cat sprays an object, it releases a foul smelling odor akin to ammonia. How can you stop your kitty from performing his normal instinctive behavior of spraying? Understanding cat psychology can resolve this problem. Employing a cat whisperer or cat psychologist to come into your home to resolve problems can also lessen the problem. Even with taking all the precautions, cat spraying will be difficult to eliminate completely but can be easily be controlled and minimized.

Nothing spoils your expectations of a happy relationship with a cuddly kitty than the problem of aggressive cat behavior. A cat scratch or bite can be more than just painful at the time. Cats have a considerable amount of bacteria on their claws and especially in their mouths and these injuries can easily become infected.

Instead of worrying about the consequences of aggressive cat behavior, it is much better to understand what causes it and to head it off before it starts whenever possible. This can begin with the play of tiny kittens, and requires understanding a cat’s normal instincts and their psychology.

Cats are predators naturally, and kitten play comes from their instincts to capture prey. Some aggression is natural, but it is important when socializing kittens to set limits for the behavior and provide appropriate substitutes to absorb it. When a kitten bites or claws you, no matter how “cute” it seems, it must be rebuffed with a “No!” you must stop petting or other wise reinforcing the conduct. It won’t be so cute in a 15 pound adult.

Always have cat friendly toys and furniture available for your four legged friends. These provide safe outlets for aggressive play and healthy scratching and stretching. Stand firm and be clear that biting and clawing people is unacceptable. Use kind words and occasional treats to help reinforce every positive behavior you see, but don’t use violence to punish your cat. This will devastate your relationship, and often makes the cat more aggressive.

Consider that a cats health can explain aggression. Cats can’t speak, so when they are sick or overstressed, they may show it through aggressive behavior. A cat can feel stress from a new pet in the house, a change in the house or in its diet. A cat can also feel stress from a new noise from outside, such as construction. To try and reduce stress and aggression, slowly expose the cat to changes and newcomers, human and pets alike. As soon as a pet becomes aggressive, take them to the vet immediately for a checkup.

Some think aggressive cat behavior may also be caused in part by the diet, so discuss this with the veterinarian as well. Obesity may cause joint pain in older cats, so weight loss can improve both mood and health. Again, speak with a vet because to rapid a loss can be dangerous and even fatal to a cat.

Make sure you pay attention to what your cat is trying to tell you. Even though they are basically gentle animals who love to purr while being petted, if they are over stimulated you may find yourself stroking a cat who tries to bite you. Beware of a swishing tail, an arched back and flattened ears. Your kitty is signaling to you to back off and give him space. Start behavior training with consistent reinforcement for good behavior as soon as you get a new cat. You must also immediately start learning your cat’s body language. These simple steps will ensure a calm, pleasant pet for your family.

Any plans for happily ever after with your new feline friend are quickly ruined by aggressive cat behavior. If you are victim to a cat scratch, clawing, or biting, it can be more than a temporary ailment. If you do not clean and dress the wound, it might easily become invaded by bacteria and infection. Then it can be a really serious issue. Unusual feline aggression may often be contributed to the cats health. Without the ability to communicate many cats will use aggression as a signal that they are ill or have been injured.

More people than you would think dream of a paradise-like vacation. Most dream of Hawaii in particular, but more often then not consider this out of reach due to budget. With Hawaii rentals, this is just a vague misconception. A travel agent can locate a wide array of properties in Hawaii that contain all the facts and contact information for these rentals. Or if your a do-it-yourself kind of person, Hawaii rentals can be found by any person on the internet.

A wide range of Hawaii rentals can be found. You can rent by the day, week or month with all different prices. Rentals for the frugal and for the extravagant are available and some with extra perks. A Hawaiian vacation can be very relaxing with your friends or family in a home like atmosphere rather than in a huge hotel or Hawaiian resort. This type of vacation can be on your own schedule.

The main disadvantages of self-catering apartments are that you miss the perks you would expect from a hotel. But whilst you won’t receive maid service each morning to change the sheets or room service on demand, the housework in a rental shouldn’t be too time consuming. On the plus side, you won’t find yourself wasting money on an overpriced mini bar and if you are missing the room service, there are plenty of takeaway restaurants in Hawaii that you can sample. To get around, you can easily use taxis or public transport or you could rent a car if you prefer.

Sometimes you will be traveling with family and friend and can share Hawaii rentals to save a lot over those hotel prices. If you are people who get along well, this will only add to the pleasure of the vacation. The minor housekeeping tasks can be shared as well, and one large vehicle rental to can cut down on transportation costs. A fifty cent bowl of cereal for breakfast at any hour you choose is far better than a $10 breakfast in a hotel restaurant where you get breakfast when someone else says you can have it.

Hawaii rentals can provide couples with privacy not available in a major hotel. The ability to have time entirely to themselves compensates for the lack of perks. Indeed, some of these properties offer maid service and other amenities. Consult your travel agent to ensure what services are included with any given rental. You can also conduct a search of your own over the internet to discover the details of any given rental, so that you know exactly what you are getting.

When planning your trip you may wish to check online and other resources, however a travel agent may know of cottages available for rent or luxury villas or condos that are much more pleasant as well as less expensive than the usual hotel room. Also, a good travel agent often has connections and information that helps him find cancellations or last minute availabilities. This can make for a much more comfortable, as well as affordable, vacation.

Many people dream of vacations in paradise and want to go to Hawaii to make them come true. A Hawaiian vacation with friends or families may be less stressful in a home like atmosphere than it is in a big hotel or Hawaii resort. For a Hawaii honeymoon, Hawaii rentals can be an experience that you can not get at a big hotel. Also sharing rentals can save a lot compared to hotel prices, and your friends and family can acquaint as well. For the best deals, it’s generally a good idea to use a travel agent.
