What are the interesting inventions in Chinese history

To exaggerate, there are a lot of ruthless many interesting inventions in Chinese history, these inventions, benefit the society and the people, make the people's life layer by layer, vigorously and effectively solved the problem of the people's fundamental difficulties in life.

Here, first of all, thanks to the invention of interesting props, and then introduce you to three interesting inventions.

1. Geodesy

Geodesy? What does it do? Digging a hole in the ground? Haha, of course not, the geodesic is a measuring instrument.

A long time ago, that is, the Eastern Han Dynasty, a celebrity: Zhang Heng invented a great creation, I have read the ancient books, I remember the origin of the geodesic instrument is because the earthquakes were too frequent, to the people to the community caused great harm, injury injury, death, death, collapsed houses and trees have to be rebuilt, in order to reduce the loss of such a smart Zhang Heng, after a hard inquiry, and finally invented such a, but also the only one in history that can predict the future of the world. is the only one in history can predict the earthquake instrument.

This instrument is very interesting, but also good-looking, it has eight directions, each direction on the dragon's head, eight directions on the dragon's head are one, its mouth is containing the dragon pearl, the place below there is a toad, the dragon pearl and the toad is a one-to-one correspondence.

Assuming that an earthquake on one side, the dragon's mouth contains the dragon pearl will fall into the toad's mouth, which is too practical for predicting earthquakes

2. gunpowder

As we all know, gunpowder is one of the four great inventions, it does not look good, but it can save or destroy the world, the might is boundless ah! It is really loved and hated.

How interesting? Gunpowder is composed of a small gunpowder, looks inconspicuous, but after ignition, rumbling, such as earthquakes, the house destroyed, without artificial, you can demolish the house, huh!

There is no one asked, so powerful things, who invented it? No, no, no, not a human invention, gunpowder originated in alchemy, which has sulfur, saltpeter, it is relying on these chemicals to react to play the role of the explosion.

Fantastic and interesting, right? If you also want to invent something like gunpowder, from now on, learn chemistry!

3. Abacus

Turning to the history books, at the end of the Han Dynasty, in the period of three points, it is Guan Yu invented the abacus, but this is not invented by Guan Yu, there is still to be verified, I think, this invention, and the four great inventions can be compared.

The abacus is a "man", is an auxiliary tool for arithmetic, with the brain, with the hand break, with a matchstick count, counting a 1 + 999 will take a long time, but since there is an abacus, can save time and effort.

Insert a digression, you will use the abacus? A lot of people don't, but I do.

Talk about the appearance of the abacus, it is a bead with a one by one, dialing the time does not hurt the hand, very fluent, as long as the algorithm will be mnemonic, counting up very quickly, but with the abacus counting time, to hand to the eye to the brain to the, can not be distracted, and closely coordinated.

Whispering to you, more work with the abacus, can exercise your brain, reaction faster oh.

The above three interesting inventions explained, in fact, the history of China's interesting inventions, such as printing, compass, papermaking, interested in Baidu to understand, but also can inspire you to another potential Oh.
