The reason why I joined the global forum camp is because I wanted to improve my English skills. And the reason why our group chose Goryeo's technology is because we wanted to find the physical principles contained in it as we learn about its science and technology. Also, what I knew about the cannon of Goryeo Dynasty was the principal of action and reaction. And as we investigated the cannon, we found that they were rocket weapons. Also my role is to investigate a missile which is the current weapon involved in cannon and make ppt. Through this camp, I think I can gain patience by trying to study English with my poor English skills.

Background knowledge

What is a cannon(Chongtong gun)?

  • A type of weapon used to fire arrows from the Goryeo Dynasty.
  • The chongtong gun is a cannon ball of the Joseon Dynasty. The names were divided according to the size, weight of gunpowder, the number of bullets, and the distance to which they were used, according to the order of 천자문(千子文) was separated by 천(天)·지(地)·현(玄)·황(黃)
  • A cannon is a large, uncarrying weapon with a large firing range and a greater range than the gun.

Since the introduction of artillery in Europe in the middle of the 14th century, main steel shells replaced stone at the end of the 15th century, At the same time, in France, a new lighter a cannon cast in bronze was placed on a horse-drawn motorcycle carriage, which led to the emergence of field guns. The new mobile French field gun has introduced the concept of a trunnion, making it easier for guns to be placed on permanent cartwheels, allowing for relatively accurate aim and range expansion.

The origin of the invention of metal types

It was designed to make up for the fact that it is difficult to preserve woodblocks for a long time and to break them easily.

Middle Ages

European and Chinese cannon

The cannon of the Goryeo Dynasty

German metal movable types

The metal movable types from the Goryeo Dynasty

1. It is carved into the wax one by one letter to form 어미자.

2. Wrap the wax and then form a mold.

3. Pour molten iron from copper, tin, and lead into a mold.

4. Remove and polish metal types made from molten iron.

5. Arrange the types according to what you want to print.

Modern times

Modern technology

3D Printer

This is a photo of a 3D printer.[1]

Today, a three-dimensional printer(3D - printer) has been created combining traditional printing technology with the wisdom of our ancestors. Three-dimensional printing is a manufacturing technique that produces three-dimensional objects by spraying a continuous layer of matter. By using this, they were able to create objects in three dimensions, not in two dimensions.

Missiles

The rocket weapons, including cannon, have at present developed into missiles. A missile is a generic term for a weapon that is driven by a rocket, jet engine, etc. and is guided until the target is reached at the point of induction. A missiles don't just shoot at targets like shells and fly away.also it's got an induction device inside it After it's launched, it measures its speed and direction. Missiles have the ability to hit the target by as amended it.
