100 outstanding inventions, I am very proud, I am very proud!

Since ancient times, our people have a glorious tradition of invention and creative thinking.

Like dragon and phoenix.

The decapitated head of the magical animal Phoenix is ??combined with the feathers on a peacock.

Rondo's creativity, the dragon is a magical animal that combines the head of a horse, the body of a deer, the feet of a snake, the claws of an eagle, the body of a dragon, and the tail of a fish.

In addition, the famous British scientist Joseph Needham conducted in-depth research on the scientific and technological achievements of ancient China and wrote the world-famous great work "Chinese Science and Culture" (translated book "Science and Technology in History").

Under the guidance of Dr. Joseph Needham, Robert Temple published in 1986 a book "China - the Land of Inventions and Discoveries" with a concise and popular text introduction of "the first in the world".

I will introduce it to you through the invention sequencing below.

1. Photosensitive drum: In 3500 BC, there is a legend that the Chinese had artificial drums.

3000 BC, frame or container of a drum beast from Piedmont.

By 1000 BC, in Mesopotamia, Sumerian drums were used to paint pictures of the human body.

Later there were small bronze drums and large bronze drums.

Cavalry in the 15th century, drums and orchestra in the 17th century.

The soundtrack to Purcell's "Queen of the Faeries" in 1692 used it.

This drum is now called a timpani, a bass drum in the 19th century.

Drums will make unique, durable, and powerful beats.

In the 2nd century BC, the Chinese invented the timpani.

2. Binary system: According to legend, Fuxi invented the binary system in 3000 BC.

The "Book of Changes" is the Five Classics "Book of Changes" and it is one of the oldest classics in the country.

"Book of Changes" According to legend, the hexagrams drawn by Fuxi around 3000 BC, King Wen, and Zhou Chonggua of Duke University were resigned by Yao Ming (Yao Ming), and, after revision by Confucius, became the "Book of Changes".

Contemporary computers use not decimal, but binary.

Who invented binary?

"Book of Changes", "The Book of Changes" is binary. In other words, Fuxi invented the binary system. Fuxi and Shennong are said to have tasted all kinds of grass and found food, which is our only primitive agriculture. Fuxi can be described as a big man. Our social progress is based on the pioneers of Beijing.

The altar was built to commemorate Shennong (i.e. Fuxi) and express his admiration for his descendants. 3. Wire rope: In 2800 BC, the Chinese had mastered the technology of creating hemp fiber ropes. In the AD era, hemp fiber had become

The main rope material in most parts of the world. The era of man-made rope making machines began in the 1950s. Manila rope with a length of about 2 mm and a diameter of 5512 kg will be broken, and a similarly thick nylon rope can be broken.

It can withstand 13227 kilograms. 4. Compass: According to legend, the Yellow Emperor of China invented the compass in 2700 BC. The compass was used by the Yellow Emperor to identify directions, and according to historical records, the Chinese had used it as early as the Warring States Period.

In the 3rd century BC, "Han Feizi said:" During the Warring States Period, someone used "Ian" (compass). Shen Kuo's "Mengxi Bi Tan" recorded more details about this.

A compass was installed on it. As a navigational tool. In Europe in the 11th century, magnetic needles were used to float in the water. Around 1250, magnetic compass systems in the Mediterranean region were installed on a card and maintained balance on a central fulcrum.

In the 19th century, iron ship compasses were mounted on a frame to correct errors caused by magnetic compasses on ships and aircraft.

Compass. Based on the principle of rotation of the apex to stabilize the attitude of the stars, the gyrocompass has 2 advantages: both close to the metal and deflection to true north rather than magnetic north. In 1908, Germany made the world's first practical instrument.

Compass American Subli system. The "Dravidian" ship was successfully tested in 1910 and was soon adopted by the United States Navy. In short, the compass was one of the 4 great inventions of China, and later spread throughout the world.

Various places have made a great contribution to the development of the global shipping industry, as well as other aspects. 5. Fishing: The Chinese already knew how to fish in 2500 BC when our people could use artificially hatched eggs to increase consumption.

During the 1960s and 1970s, artificial breeding of salmon and other fishes occurred in Europe and the United States. Fish farms in the United Kingdom and other Western European countries now produce approximately 10 tons of freshwater fish per year. BR /> 6. Equatorial astronomical instruments.

: In 2400 BC, the Chinese invented the equatorial astronomical instrument. 7. The decimal counting system: The Chinese invented the decimal counting system in the 14th century BC, which is very important to modern science and is the earliest official evidence of it.

By the time, in 976 AD, Spanish manuscripts were discovered in China, which had been used by the Shang Dynasty as early as the 14th century BC, an example of a Chinese account of "547 days" was seen in an oracle bone inscription unearthed in the 13th century BC.
