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.

Lubrication of Domestic Clocks

Domestic clocks are one of the most ignored watches in the entire household. We make sure that our wrist watches are well maintained with good servicing, battery changes and of course lots of lubricating. But domestic watches are practically ignored till the battery runs down. Even then, we just replace the battery without getting any servicing or lubricating done on it. That means that the watch continues to run without any care or oiling till they finally expire and die! But just like wristwatches, domestic watches need to be maintained well too with regular cleaning and lubrication and care. Clocks are larger than wristwatches so a little too much lubrication is OK here.

But still there are rules to be followed in lubrication and care of clocks like-

* Try to use just a single drop of oil in the watch works to make the watch remain on time. These are bigger watches so they don’t really require you to be precise but it’s a good idea if you are. Carriage clocks require a smaller amount while long clocks and grandfather clocks require much more.

* Try not to scrape the oil pots while oiling watches as it scrapes up unnecessary settled grit into the workings of the clock. This is especially true of incalite pots. Use only fresh oil and discard any which has more than five years on the packing date on the seal; protect the oil you are using by storing it at room temperature and away from direct light. An ideal temperature would be about 15 to 20 C or as stated by the manufacturer of the clock. There are several points on a domestic clock where you can oil them and the oil will them spread to all over the clock workings. Good places to apply lubrication are at oils sinks or pivot holes, escapement pallet faces, weight pulley bearings and points of contact between different parts of the mechanism.

* Make sure you do clean the mainspring and refit the watch springs after you have oiled the domestic wall clocks. You can also apply heavy grade mineral oil around the edges of the barrel cap. Capillary action will make sure that the oil spreads all over the mechanism.

* Do not lubricate or oil pinion leaves and gear teeth, as they will slip while revolving. Another place to be careful of is the ratchet and the great wheel arbor in the main clock facings.

* The frequency of oiling depends on how frequently you use the clock and the location it is based in. Synthetic oils are very stable and do not deteriorate but non-synthetic oils do. The residue leaves a gummy deposit in the watch that can destroy a good watch.

* Contamination with dust will however really cause a tremendous amount of wear on the clock and that can damage the mechanism. Reapplication of oils is fine after the old one has been wiped off.

But do make sure that you do service the watch at least every two years to maintain optimum working conditions.

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.
