the subject of diving

Human interests. And was the subject of diving from the old days when Roi.
Over the past year, or Greek. Evidence of the paintings on the artifact
Or on the stones. In the early days of diving. Is to feed animals such as sea
Find antiques for a living. Repair of the damaged vessel. Or to sink enemy ships or
I want to dive into. The conditions of life under the sea.
Diving has become the order until Mankind has discovered ways to breathe underwater.
However, it depends on each dive. In the past, you can dive at a time.
Short, which sometimes will not survive to their implementation.

In the heyday of the Integrated Church of the Sea of ​​Greece had been boarding Scyllis.
As a prisoner of the Persian king Xerxes, which comes with a navy.
King Xerxes Scyllis know when to attack the Greek ships, among them a knife fight.
Comes away from the dive boat. The Persians are trying to find Scyllis water.
I guess that was found and ç. He drowned, but it appeared Scyllis above.
In the evening and headed for the fleet of King Xerxes, and he cut inside.
Rope to tie them to the boat slip and use the trunk of a tree (kg) were used as a conduit.
Breathe in the water to hide from enemies visible.

In the early days of diving. I think the search for ways to stay underwater for a long time. Such as pipes.
Of trees used in breathing. If the pipe is not good because it takes longer than two feet.
It works because it makes breathing impossible. The pressure of the water. Or even try to dive from the air bag into the water, but it is.
Without success, because when the air exhaled. It is mixed with the air.
In a bag to breathe new time will be much carbon dioxide is mixed with.

In the early days of diving with underwater breathing apparatus that
In 1600, we held a man has invented a way to stay underwater for as long as there was.
Initiatives for innovation, diving bell is a bell-like, based on the upside.
The scene was less strong when the water is about two to three feet, the bells will trap air.
Compressed into the top to get under the diving bell by a head above the water.
Ç is a breath of air. When inhaled. It's full of bells, or to explore underwater.
The black one can dive for about one to two minutes only to come back.
The bell to breathe again.

Diving has evolved with the years, respectively. Fri Since 1600 residents.
England, in partnership with the French. Has developed a diving suit made of leather using.
Flow of water. This time, it can dive to a depth of 60 feet and beyond.
Since then it has developed the equipment, which can dive very deep.
And longer, respectively, in the year. Fri 1830 was the development of equipment.
The complete performance of the whole. Air supply from the surface.
(Surface Supplied) helmet diving (Diving Helmet) to increase capacity.
In water or under running water to recover the ship submerged in the beginning was the man.
We have developed a device, but in one dive.
Lack of understanding of the dangers. Of diving. And when they are diving.
Deeper and more prolonged treatment with water. It happens to many divers.
It is a mysterious disease. I explained that the cause of, and in early.
Acts of 1900 and the two French scientists named in the Scotland.
Paul Bert and John Scott Haldane has made a serious study of the effect.
The pressure on the body. Man under the water. Until it can be.
Limit of diving safety of the use of compressed air. At the same time.
There has been developed. Such as air compressors.
In much carbon dioxide removal system to adjust the air pressure to be effective.
In order to be a diver. In the water longer and more secure.
