How was the boat invented? How the boat was invented Learn about the invention process

When ships first appeared, and who was the first to complete this great invention, no one can say for sure. But one thing is certain, the Chinese nation.

It was one of the first peoples to build ships. Speaking a little later, in the Neolithic.

Canoes and rafts are already ubiquitous in the rivers. There are many myths and legends about the origin of the canoe, such as "Fuxi.

The wood is the boat, and the wood is the wedge". It is said that a man named Fuxi cut open the cut down trees and hollowed them out to create a primitive boat, the canoe; The sharpening of the wood is the pulp of the rowing boat. Among the primitive rafts are the bamboo rafts that we are most familiar with, as well as birch bark rafts, cowhide rafts, etc.

Around BC, plank boats appeared. The use of sails is perhaps one of the proudest of human beings. Due to their small size and the fact that most of the early wooden boats were short-distance voyages, they could rely on pennies, oars, and oars, and could rely on manpower, albeit at a slower speed.

As the ship grows larger, especially over long distances, against the water or against the wind, manpower is far from sufficient. With sails, when the wind is against the wind, take the zigzag route, and you can also skillfully gather the wind power and become a kind of power to push the sailboat forward. Since then, mankind has begun the voyage of "hanging on the clouds and sailing into the sea".

Around the turn of the century, wooden sailing ships reached their peak, and various warships and merchant ships appeared that could reach all over the world.

The successful sea trials of the "Klermunck" marked a new era in the history of ships: the new era of steam power began to replace the era of sailing ships. It also heralded the coming of the iron ship age.

Today's boats can not only sail on the surface of the water as if they were on the ground, but also sneak below the surface (submarines, flying off the surface (hovercraft). Recently, Japan's Mitsubishi Corporation is developing a cruise ship that does not feel bumpy. It is believed that in the near future, people will sail on rivers and oceans as smoothly as at home.

刳 (ku) wood for the boat, the wood for the boat, the benefit of the boat, to help the unpassable, to the far to benefit the world, cover all the water.

1. Boat is a water transport with the longest history. The invention of the boat can be traced back to ancient times, when the ancients were inspired by the phenomenon of fallen leaves and tree trunks floating in the water. For example, it is written in the "World Book":

Watching the fallen leaves because I thought it was a boat. It means that the ancients saw the leaves falling on the water and drifting, so they built boats.

2. The earliest ship invented by human beings was a canoe, and the manufacturing method was roughly: cutting one side of the log and digging it into a concave shape, that is, a ship. In a swamp in Starkar, Yorkshire, England, a wooden paddle dating from 7500 BC was excavated, which was supposed to have been used for a type of canoe.

A canoe found in Pesse, the Netherlands, dates from about 6300 BC. This canoe can be made quite large, and a canoe found in Brig, Lincolnshire, England, is 16 meters long and 16 meters wide. The early Egyptians and Mesopotamians probably built their boats from reeds, and the bundles of reeds were coated with a layer of bitumen or resin to sail through the water.

Other boats were made of animal skins, and the Assyrian soldiers in ancient reliefs crossed the river in such boats. One is the Irish's wicker boat, which is made of wicker, covered with animal skins and then tarped, and the much simpler boat is inflatable animal skin, which is still found in the middle and upper reaches of the Yellow River in China today, sheepskin rafts.

3. Pottery boats and six pottery paddles were unearthed at the Hemudu site in Zhejiang, which simulated the shape of the boat and the toys could show the degree of use of the boat at that time. In a slab wall in the cultural layer of the site, a remnant of wood with an arc-shaped section and a pointed round end was also found, which may have been originally a canoe and was used to build a slab wall after being abandoned. Wooden oars have also been excavated at other sites.

Obviously, the ship was an important means of transportation for people at that time. The invention of the boat is a sign that mankind has begun to conquer nature. With the help of boats, people have extended their feet and expanded their horizons, the fishing industry has developed greatly, the food has been abundant, and the clans and tribes can also break the blockade and increase contacts with other tribes.

Although the canoe could not resist the strong wind and waves, the ancestors still risked being buried in the belly of the fish and boldly used it to float across the sea, showing the tenacity and tenacity of life.

4. By the time of King Cheng of Zhou, there was a record of "Yu Yue offering a boat" in the literature. In the Spring and Autumn Period, Wu was known as a country that "could not be used to scrap boats for a day", and Goujian, the king of Yue, proudly described the residents of the water towns of Yue as "boat-based, horse-based, and wind-like", which was really as chic as an immortal. In the Western Han Dynasty, the number of ships in Wu even became a symbol of national strength.

The origin of the ship is thousands of years ago. At that time, people found it difficult to cross the river. If the river is shallow or the current is slow, people can wade across the river.

But when it comes to the depth of the river and the rapid current, people are helpless. Later, some people found that they could cross the river safely by holding on to a tree branch or a stake. So the larger trees were hollowed out and made into canoes to cross the river smoothly.

The development of the ship has gone through four generations: the era of boats, the age of sailing ships, the era of steam engine ships and the era of diesel engine ships.

1: Boat and raft era; Humans used rafts as their main transportation, which originated in the Stone Age. The ancient wooden paddle unearthed in Zhejiang in China in 1956 has a history of 4,000 years. Explain the history of the raft, which can be traced back a long time.

2: The Age of Sailing; It is recorded that in the fourth millennium BC, there were sailing ships in ancient Egypt. The history of the use of Heng Chuan sailing ships in China is from the 15th century to the middle of the 19th century.

3: The era of steam engine ships; In 1807, the American RFor the first time, Fulton successfully sailed a broadside paddle wheel powered by a steam engine on the ship Clermont on the Hudson River. Since then, mechanical forces have begun to replace natural forces, and the development of ships has entered a new stage.

4. The era of diesel engine ships; After the successful trial voyage of the diesel engine ship, it developed rapidly and soon replaced the steam engine ship.
