The world inventions: The origin and the history of the submarine!

You know, we have seen these submarines in the ocean outside cities in the world. But is it really suspiciously with submarines? And should we worry about anyone of them?

Today, management leading is not distorted, but it is clear and logical! The submarines you see, are not making and going into wars, but they are used for military purposes. And every nation wants to mark that the flag and the nation have an importance!

When taking the phone to Harvard, you should listen to what you see in the oceans around the world, and what the challenges really are different places. Nowadays, we are seeing submarines in the oceans, and the relevant country it comes from wants to hide its presence. You should not use too many submarines today, since there could then be a crisis and a conflict between nations. But we see most of the submarines used for the military today, and even The Beatles was singing about submarines, the yellow submarine!

The submarines can dive to avoid enemies. Some submarines in the oceans in the world today, are equipped with torpedoes and missiles. And there is high competence to produce them, and also to use them. And ever submarine should be careful when coming into national waters.

The submarine has historically been a ship that has functioned as warship, and many nations will not that other nations discover them. The history of the submarines goes back to the ancient Greece. Many submarines have been made through all history, and there are reactions in the populations today, if one submarine comes too near a nation’s territory! And in the medieval time, there have been several models, descriptions and sketches about and around the submarines!

So, what was really the story about the submarine in recent times? In 1405 Konrad Keyser, drew a kind of technical diving suit in his contribution called for Bellifortis. He came from Nürnberg in Germany. Leonardo da Vinci constructed on the drawing board a submarine for one person in 1515. These ideas were developed even further, and in 1604 Magnus Pegel described in a book for the first time the basic thoughts and the assumptions for a diving boat. The Dutch inventor Cornelius Jacobszoon Drebbel was the first person taking the step from theory to practice, when he in 1620 built the first maneuverable underwater vehicle, and this was really a leather coated wooden boat. On behalf of the count of Hessen, the Frence physicist Denis Papin (professor by university in Marburg) constructed in 1691 a diving boat, but this boat did not survive the trial in 1692. But the idea was developed even further. The first operative submarine which we know today is a Dutch model from 1624. The submarine developed here had 12 rowers and could operate at a depth of 5 meters.

There are different submarines for different purposes that are used today. And you have the submarines in different classes to say which type the relevant submarine in question has. So, many submarines look being the same as before when seeing them, but there are also differences in constructions and differences in production. And therefore, what you see several times at the same or the different of what you have seen before due to your experiences in the oceans. And as mentioned, the submarines are used for military purposes nowadays, since no nation in the world wants interruptions and wars, but one wants peace and love and having normal lives in harmony and in cluster with each other! Being a boat under the water level, and not being as other boats, have triggered the interest for the submarine as being a lasting affair! When seeing a submarine, we are wondering about why and how! Hence, no submarine dares to be to close to people!
