Diving - this is an opportunity to relax and immerse themselves in the bustling life of a world full of mystery and adventure. The concept of 'diving' (translated to English - descent into the water, the diver dive). The ancestor of diving is a well-known man, Jacques-Yves Cousteau. It was he who, having created in 1943 scuba, opened for millions of people underwater beauty. Cousteau himself later said that this discovery not only gave humanity the abyss, but also give people the opportunity to use the underwater world on your own.
Diving - a recreational scuba diving. It should not be confused with the diving business, as a diver - is first and foremost a professional, the last special. training, trained to dive, usually at great depths and carrying out special works there. Divers is it just enthusiastic people to dive with scuba diving under the water to enjoy the contact with nature and the underwater inhabitants.
Amateur diving - this dive in the crystal clear waters of tropical seas, surrounded by colorful fish and corals, and the study of the sunken far from any ship of the island. The diver and his partner put on gear, enter the water and begin to study the underwater flora and fauna, moving slowly in the water column.
They invented a diving suit with a steel helmet. It consisted of a steel helmet with portholes and air hose, and a rubberized suit. At his feet a diver to wear special shoes with lead soles, and on the shoulders of a special dickey equipped with metal screws for fastening the helmet. I invented this suit Englishman August Siebe in 1837. This suit is without significant changes there and now, today, and probably will last a long time. But in a suit diver always attached the hose to the ship, where there is an air pump. Consequently, the freedom of navigation under the water was out of question.
Again humanity was faced with a problem: what must still come up to the diver had unlimited freedom of movement in the water column.
And it was necessary to come up with scuba, balloon with compressed air, which would be fastened to the diver's back. What did Jacques Cousteau in 1945. It is supplied with compressed air cylinder and a special valve, which joined the breathing hose. An air hose to an end device that exhaled air directed outward in the water at the same time equalizing the air pressure to ambient pressure.
Some people because of lack of time are unable to communicate normally with friends and acquaintances. They have to settle for "fast communication". For example, when the moment of the session, I work to prepare for exams and I have no time to walk or to talk. At the Institute, I see a lot of my friends and I, thus, there is a "rapid communication". We for 5-10 minutes , asking how each other's business, quickly sharing something important for yourself and disagree. Such meetings have had their effect in day 5 pieces, which allows me to fill the need to communicate. Such communication will not make the person better or worse. On the contrary, very pleased to meet the person to whom you have sympathy and "spread the words".
