,[link widoczny dla zalogowanych]Michael Phelps is now a legend at age 24 upon breaking his own record of the most athlete to garner most gold in the Olympics. He is a master albeit an institution in his athletic field of swimming. And just as to complement Phelps extraordinary ability in swimming,[link widoczny dla zalogowanych], many private and government funded institutions have expressed making a deal with him - to give him the best swim gear that will sure amplify his ability in the water. Surely, in terms of swimsuits, Phelps always has knowledge on it.
NASA, being known for breaking the impossibilities in physics and other fields of science, made another leap when it introduced a special swimsuit that can boost an athlete's ability in swimming. Unlike Phelps, Steve Wilkinson, a NASA researcher does not have enough physical ability or enough knowledge about swimming. All he knows is that swimming involves physics and when physics goes into his way he will have a say on it. Just like any moving object,[link widoczny dla zalogowanych], a swimming person experiences a drag - thus realizing Newton's law on friction. Wilkinson knows how to lower or if not diminish drag when an object moves in air or in water.
Previous studies and athletes' experiences proved that the clothing they use greatly affects their performances. Even if athletes wear minimal clothes drag can still be experienced. In fact,[link widoczny dla zalogowanych], the more skin is exposed the more drag it could create because our skin is not design with a natural lubricant that like fishes and other aquatic animals. To answer this problem, Wilkinson made a study and invented a type of textile that has the ability to reduce drag. This swim uniform claims to outline the body of the swimmer making his or her muscles to shape like a bullet. The cloth that has been used in this swim wear is also said to be water repellent. This makes this swim suit advantageous than others.
Because of these qualities the men in corporate uniforms at the Olympic committee and other competitors have expressed doubt that other swimmers might unfairly fare with their American counterparts. Speedo, the private company who has the sole manufacturing right over this invention expressed that the suit is just a suit and it will not make a swimmer. It is still the athlete that will have to do work to win. Right now, Speedo's online uniforms store particularly the page that offers these swimsuits is no longer available over the internet.
"We evaluated the surface roughness effects of nearly 60 fabrics or patterns in one of our small low speed wind tunnels," Wilkinson said in an interview. "We were assessing which fabrics and weaves had the lowest drag. The tests have generally shown the smoother the fabric,[link widoczny dla zalogowanych], the lower the drag."
More than the issues, it is quite interesting to think that we have unleashed knowledge and invented another something we can be proud of. Thanks to the people in NASA.
Apart from diamond and gold, gemstone is also a valuable element on Earth that is found in very less quantities. Such rarity makes it even more precious, thus, mostly desired by anybody, especially women.
General Idea
Gemstones, also known as gem minerals, are defined as uncommon natural minerals that are being utilized for personal embellishment and deemed as a valuable asset, next to the precious gold and diamonds. By nature, these minerals are sturdy enough, as they are naturally formed.
Scientifically, these gemstones are naturally formed inert crystalline elements that seize physical and chemical properties, which may vary between fixed and very fixed boundary.
Significant Use and Purpose
The significance of gemstones is greatly manifested in every woman's facade. They are perfect personal embellishments that augment beauty to those who have them. Gemstones are representations of distinctiveness, resilience and exquisiteness.
What Man has Done ,[link widoczny dla zalogowanych]!
Because of the fact that these gem minerals are now rarely found on Earth,[link widoczny dla zalogowanych], man has once again utilized his power to enhance things, for a purpose of upholding the existence of such things, called the authentic gemstones. With the human intervention, the rarity of such mineral does not hinder the reproduction of more 'gemstones' that look more akin to the original source.
A matter of this fact,[link widoczny dla zalogowanych], there are two types of gemstones available, other than the real ones:
(a) Value-Enhanced and
(b) Synthetic gemstones and minerals
Value-Enhanced Gemstones: These are the enhanced minerals, which entail partially authentic. The mineral enhancements are made possible with the utilization of special procedures and various treatments to the genuine gemstone. Such procedure is widely known as gemstone rough. What they usually do is take certain amount of the original materials and mixed them with other forms of artificial substances and components. As a result of the process, value-enhanced gemstones are being produced.
There are four value-enhanced gemstones available nowadays:
oiled emerald
heat treated sapphire and ruby
diffusion-coated sapphire
irradiated-colored diamonds
Synthetic Gemstones: On the other hand, synthetic gemstones are those that are purely man-made and mimicked. Thus, they are called artificial gemstones. Artificial gemstones are composed of man-made substances, physical components and crystal structures that would make them look more similar to the original gem minerals or gemstones. They are also known as gemstone resemblance, or the synthetic diamond and sapphire.
Tips Before You Buy Gemstones
Get only the best gemstone for your self. It would not hurt if you spend more time to scrutinize whether the gemstone item you are about to procure is authentic, value-enhanced or synthetic gemstones. As much as possible, try to find the authentic stones, if not then go for the value-enhanced rather than synthetic gemstones available. Be sure to get only the best value for the money you have spent.
Want to check whether the gemstone you bought is real or not? Simply browse to the website at "Gemstone Buzz" and find all the information you require regarding Gemstone Identification.
If you don't find the answer, you can post your question in the Gemstone Forum. You will surely get help to verify your gemstone and also resolve other doubts regarding information of gemstones.
