The physics behind a parachute is easy to understand. But making real ones are far from easy. Making toy parachutes seem like a good idea for an easy science project but experimenting with different variations is not as easy as tying strings to a fabric. Making parachutes for use in real life takes a lot of risk and accuracy.

Before modern parachutes gave us the thrill of skydiving it took a lot of guts for early investors to design parachutes that actually work and not fall them to their death. The history of parachutes went through a lot of development and a few deaths.

The modern parachute was invented by Louis-Sébastien Lenormand in 1783. However there are earlier versions of parachutes created by a few centuries earlier. Before the silk parachute was invented, there were basic designs built that worked in the same principles.

Parachutes, past and present

The earliest form was a cloak attached to wooden struts. It was made by an Arab Muslim named Arem Firman in the 9th century. He jumped from a tower in Cordoba and suffered only minor injuries. Parasols were used in China for entertainment. It allows entertainers to jump form high places and float to the ground.

Leonardo da Vinci also sketched parachute with conical designs. It served as an escape device to enable people to jump from burning buildings. In 1617 Faust Vrancic was the first person to be able to make a successful jump with a parachute.

Jean Pierre Blanchard developed his own parachute as a means to get off a hot air balloon. His first demonstrations were done with a dog as the passenger. He later on unintentionally put his invention to the test as he escaped from his ruptured hot air balloon.

In the 1790′s he made a parachute out of silk which were more stringer and lighter than previously used materials. Early parachutes were made of linen with a wooden frame.

Andre Garnerin invented the vented parachute in 1797 and made a successful jump using Blanchard’s design. The vented parachute improved stability during descent. Gleb Kotelnikov invented he knapsack parachute. It was popularized by Katchlen Paulus and Paul Letterman.

The first major use of parachutes was in the military. It was by artillery spotters and pilots. Unfortunately the parachutes were heavy and pilots were not able to use it entirely. The German Air Service provided parachutes to their pilots. Unfortunately there were many setbacks that most of the pilots died when using them.

Golf is one of the few sports that is around today that is growing rapidly in popularity and has a huge draw for numerous types of people to play. What may seem like a rather mundane sport has actually started gathering the attention of children and even middle-aged adults as well. In the past Golf focused primarily around older adults, but as time has gone on, this has changed dramatically. This brings about the need for even more golf instructors that are teaching everyone to play, yet at the same time, it becomes much more important to select a good instructor. In the past when Golf was not quite as popular, your options for instructors may have been limited, now you can choose exactly whom you would like to work with.

This is great news for those who are trying to decide upon the best Golf instructor for their needs. If you are trying to pick your perfect Golf instructor there are a few things that you should always keep in mind. The first is you need to pick someone who obviously knows what they are doing. This means you are going to need to take a bit of time to look over their credentials. Learning to play golf by playing Nintendo Wii Sports is not an acceptable answer when you ask for credentials. You would like to look for some professional or at the very least semi-professional playing experience. After all, you would ask a librarian for help in learning how to find the books you need at a library so you should follow the same theory for a golf instructor as well and choose a professional.

You want to also look for someone who makes you feel comfortable. If you do not like working with men much you would be best off finding a female instructor, however if you do now work as well with women then a male instructor is best for you. The options for golf instructors now are quite large, which gives you the freedom to really be a bit picky when you are making a decision. However, being picky will ensure that you are satisfied with the results and feel completely comfortable working with the person. In order to really learn Golf successfully you are going to need to spend a bit of time working on your stance, this means you need someone who can help you relax, rather than standing always in a very tense and uptight position.

Search around if you are looking for a Golf instructor and get some recommendations from the local Golf courses, they can often give you some great tips about which instructors are the best and who is most likely going to be a good match for you. While you may not like their suggestion, it does give you a good place to start looking at least.
