Technology in Sports

It today’s world, sport cannot go together without technology. With the ever growing development of new technologies, they have always tried to be implemented into sports. Because technology can give sports something nothing else can, an unmistakable truth. Or so they say. Due to the fact that people are, well, people, they are bound to make mistakes. It is because we are human, we are not robots, that we can make mistakes, while robots make them only if they are malfunctioning. This is especially emphasized in sports, where human eyes can often deceive their owners, the referees most importantly, but also players, coaches and the fans. That is why these days there are many discussions about installing video technology into sports, mostly football. What does technology actually mean for sports?

Here I would like to emphasize that there are already sports using technology, like tennis and cricket, to name some. It helped the referees a lot, to minimize and correct some mistakes they make. But apparently, not all problems are solved like this. Players that have been playing for a longer period of time, and have not grown up with these kinds of technologies, are not convinced that it works properly. This suspicion is probably understandable, because when they were first starting their professional sports careers, they did not probably even dream about something like this would exist. But this technology has been tested time after time, and skeptical players, such as Roger Federer, have learned to live with it and accept it, although probably not so reluctantly.

This technology used in sports is called Hawk-Eye line-calling system, or just Hawk-eye for short. It was invented by a British computer expert Paul Hawkins. It is now used in tennis, where six or more cameras, situated around the court are linked together, track the path of the ball. Then those six or more cameras combine their separate views and make a 3D representation of the path of the ball. For tennis, or basically any other sport, this means that any close line call can be checked, quickly and accurately. This is not always used on tennis tournaments, though. For instance, the French Open is not using this technology because the tournament is played on clay courts and thus the print of the ball on the ground can easily be seen. Maybe this will change one day, because you can’t always be 100% sure you are looking at the right print.

These days there have been a lot of talks about introducing this technology to the sport of football. The sympathizers of this idea have been especially loud after the South Africa FIFA World Cup 2010, where a lot of mistakes by the referees have been made (an Argentina goal allowed although the player was offside, England goal not seen in a crucial moment). However, referees are only human, and they are bound to make mistakes because they can not help it, so i do not think all those critics were fair to them. On the other hand, a recent statement was made from the UEFA president Michel Platini, who is not thrilled about the goal-line technology, saying that this would reduce football to a video game. I don’t believe that other sports who have this technology have been reduced to a video game. Furthermore, he also admits that referees can make mistakes and that there are many cameras on the field that can catch any disputable moment. So why not help football, or any other sport, to see these disputable moments clearly and to resolve them without making mistakes. Or is it better to hear a mass of critics every time something like this happens? I am sure the referees would like this kind of help, then they couldn’t be blamed for anything and wouldn’t have to listen to all the nonsense people say about them the other day, or worse.

Why Do We Wear Engagement Rings?

The modern Western practice of giving or breaking engagement rings is traditionally thought to have begon in 1477 when Maximilian I, Holy Roman Emperor, wave Mary of Burgundy a diamond ring as an engagement present.

Customs for engagement rings vary according to time, place, and culture. An engagement ring has historically been uncommon, and when such a gift was given, it was separate from the wedding ring. Romantic rings from the time of the Roman Empire and from as far back as 4 AD often clash the Celtic Claddagh symbol (two hands clasping a heart) and so it is thought that this was used as some symbol of love and commitment between two people.

In the United States, United Kingdom, Ireland, Canada, Australia, and many other countries, an engagement ring is worn on the fourth finger of the left hand. The tradition of wearing a ring for engagement originated from the Egyptians who believed the circle was a bond between the two people who were to be married, but was initially first practiced on the fourth finger / ring finger by the Romans, who recognized this finger to Be the beginning of the vena amoris ("vein of love"), the vein that leads to the heart. The custom in Continental Europe and other countries is to wear it on the right hand; one historical exception arose in monarchical regimes, in which a nobleman entering into morganatic marriage (a marriage in which the person, usually the woman, of lower rank stayed at the same rank instead of rising ranks) would present his left hand to receive the ring (hence the alternative term "left-handed marriage").

In other countries like Argentina, men and women each wear a ring similar to wedding bands. They are made of silver when manifesting an informal "boyfriend-girlfriend" relationship. The gold band is given to the bride when the commitment is formal and the optional diamond ring is reserved for the wedding ceremony when the groom gives it to the bride. The gold band that the groom wore during the engagement – or a new one, as some men choose not to wear them during engagement – is then given to the groom by the bride; and the bride receives both the original gold band and the new diamond at the ceremony. The bride's diamond ring is worn on top of the engagement band at the wedding and thereafter, especially at formal occasions or parties. At the wedding, the rings are swapped from the right to the left hand. In Brazil, they are always made of gold, and there is no tradition for the engagement ring. Both men and women wear the wedding band on their right hand while engaged, and, after they marry, they shift the rings to their left hands. In Nordic countries such as Finland and Norway, both men and women wear an engagement ring.

Some women's wedding rings are made into two separate pieces. One part is given to her to wear as an engagement ring when she accepts the marriage proposal and the other during the wedding ceremony.

Diamond Earrings and Other Fine Jewelry

Diamond rings are the most common form of diamond jewelry, but diamond earrings, bracelets and necklaces are also quite popular. In fact, diamond jewelry has been around since the days of the Roman Empire, although it took almost 1500 years before diamond jewelers had figured out how to cut diamonds into attractive shapes that displayed their "fire," or shine and brilliance. Diamond earrings are but one way that people adorn themselves with this mystical, precious gem.

A Fascinating History

Chances are that the first diamond jewelry was from India. The tremendous geologic forces required to form diamonds exists mainly in regions of the world where one tectonic plate slams into another; the Himalayas, where the Indian subcontinent plows into Central Asia, is one such place. Loose diamonds from deep underneath these mountains have been known to appear in the rivers that flow south and westward from the Himalayas: the Ganges, the Brahmaputra and the Irriwaddy have all been sources of these rough, octagonal crystals.

Before diamond jewelers had learned the art of precision cutting, diamond earrings were not particularly beautiful; rough and dull-looking, they were nonetheless prized for their hardness.

One early example of diamond jewelry in the West was actually a crown made for a Hungarian princess well over 1000 years ago. One of the first diamond wedding ring was the one given to Marie of Burgundy on the occasion of her wedding to Archduke Maximilian I of Austria in 1477. It was not until over fifty years later however during the reign of Henry VIII of England that diamond cutting had reached a level that was suitable for jewelry such as diamond earrings.

Dull and Lifeless

If you had been buying diamonds back then, you'd have been disappointed; those early cuts did not show the kind of brilliance that we see in fine diamond jewelry today. It was not until the 1800s that art of diamond cutting had reached a level of refinement that allowed the gem's real beauty to shine through the way it does in contemporary diamond jewelry.

Fiery and Brilliant

Today, there are many different cuts to choose from when buying diamonds . Round cuts and square cuts both have characteristics in their favor, but a reliably new cut, called the "princess," has been gaining in popularity over the past thirty years or so. This particular cut combines the best features of round and square cuts, and causes the least wastage of all cutting methods – so the gem retains much more of its original weight. All three cuts however will make for highly attractive and valuable diamond earrings .

Uses And Features Of Price Computing Scales

Price computing scales design all those scales that are normally available with an LCD display, but have an additional capability of converting units to price. As is evident for this description, price computing scales are useful for weighing by traders: fruits, vegetables, and other grocery items; meat and butcher shops; bakery items like cake and biscuits, ice cream sellers, hardware etc. A trader just needs to feed in the price per unit rate as many times as the market changes. Each time he will get readings for different items with their price. For the convenience of the customers Dual display LCD screens are also available with one in front for the counter attendant and the other at the back for the customer to see. Since most price computing scales are used in trade they are considered legal, if they have been approved by NTEP or any other regulatory body in your area.

The types of price computing scales vary according to features; you may be looking for 15 lb, 30 lb, or 60 lb. Capacity which can be calculated by one scale for fruits and vegetable weighing. Small sizes that save space and have a battery powered operation facilitating portability are also in demand as fruit sellers on carts or vendors need to move it from time to time. Deli shops, meat shops, candy counters or cheese shops with limited counter space may find compact design very useful.

Price computing scales is most desirable for the cost conscious retailer who wants to be honest in his dealings, since precision in weight reading and accuracy in price conversion is a matter of integrity for them. Electronic load cells with a digital display make sure that these shop owners are satisfied. Out of all scales available in the market the better ones are easy to install and operate with easy cleaning and minimum maintenance requirements. The more attractive ones have a rugged housing, sleek profile and small footprint with some additional features like

1. Raised keys with a key beeper

2. Battery operated with auto sleep and shut off options for power saving

3. High resolution to weigh small objects and give increments like 0.01 lb or 0.005 lb divisions

4. High grade polymer surface with stainless steel pan

5. Price computing function by count (number) of objects

6. Large memory storage up to 25 PLU's

7. Price accumulation at the end of grocery purchase by one customer.

8. Tare function to enable reset of display to zero after adding object each time to a loaded pan.

9. LCD displays with large numbers and back lit displays

Price computing scales like all others need to be bought with platform size and capacity in mind according to the type, size and weight of object you plan to put in it. Minimum and maximum weight requirements must be kept in mind to allow for your full range of products to be weighed by one scale. Finally accuracy in reading and durability of scales for use in harsh environments are factors that should drive the purchase decision.
