After the four major inventions, which of them are the world s first, or the first, in China?

Yuan Longping - the father of hybrid rice in the worldThe Western world calls hybrid rice the "magic rice of the East".

1. China's famous physicist Wang Ganchang is the first person in the world to discover the charged antihyperon On September 17, China's scientists synthesized an active protein - crystalline bovine insulin for the first time in the world by artificial methods. 4. Geologist Li Siguang is the first scientist in the world to establish geomechanics Zheng Denggui, a graduate student in the United Kingdom in Taiwan, China, used in vitro fertilization to breed 4 test-tube piglets. The test tube pig test was successful, which is the first time in the world, and China has cultivated the world's earliest "artificial plant".

6. Yuan Longping, an agricultural scientist, was the first to cultivate an excellent variety of "indica hybrid rice" in the world.

The four major inventions of our country are: the compass, papermaking, gunpowder, and printing. The compass is a simple instrument used to determine the direction, and its predecessor was Sinan.

Papermaking was improved by Cai Lun, and papermaking is an outstanding invention in the history of human civilization. Gunpowder is a black or brown gunpowder that is mechanically mixed with potassium nitrate, charcoal, and sulfur. Printing is the forerunner of modern human civilization and has created conditions for the wide dissemination and exchange of knowledge.

The four inventions have played a huge role in promoting the political, economic and cultural development of ancient China, and have been transmitted to the West through various channels, exerting a huge influence on the history of the development of world civilization.

Although many important achievements of Chinese civilization are named after the "Four Greats" and "Five Greats", such as the Four Great Beauties, the Four Classical Classics, and the Four Books and Five Classics, the concept of the Four Great Inventions was adopted by Western scholars and later accepted by the Chinese.

The Four Great Inventions are a series of glorious footprints left by ancient Chinese ancestors for the world, and a symbol of great contributions to the progress of human civilization.

The compass is one of China's four major inventions, and its appearance provides a lot of convenience for identifying the direction, and it is needed in navigation, military and other fields. The invention of printing and papermaking greatly contributed to the recording of culture and the dissemination of knowledge. The surplus gunpowder was both a military necessity and an invention closely related to daily life.

The four great inventions were proposed by the Englishman Joseph, who added papermaking to the original three inventions.

The four great inventions were first proposed by the missionary and sinologist Joseph Eyjose, who originally had only three major inventions, and he later incorporated papermaking into the four great inventions.

It was the British scholar Joseph who first proposed it, and before scholars from various countries proposed the three major inventions in China, and later Joseph added papermaking to it.

The proposer of the four major inventions was not actually Chinese, but a foreigner named Joseph at that time, who summed up the four items that had the greatest impact on mankind, thus giving birth to the four major inventions.

China's new four major inventions refer to high-speed rail, QR code payment, bicycle sharing and online shopping, which is a popular word that appeared on the Internet in 2017, and these four are not China's inventions, but they are widely used in China, and are ahead of other countries, and also have a certain influence on foreign countries.

High-speed rail was first built in Japan, which built the world's first high-speed railway, the Tokaido Shinkansen, in the sixties of the last century. In 2006, China began to build high-speed rail, and in 2009, it entered the era of high-speed rail, and high-speed rail was built on a large scale across the country. At present, China's high-speed rail operating mileage ranks first in the world.

QR code payment originated from mobile payment, and the world's first mobile payment occurred in Finland in 1997. At present, QR code payment has become one of the important payment methods in China, and the most important platforms for scanning code payment are Alipay and WeChat.

The concept of bike sharing first appeared in Finland in 1965, when a number of bicycles were purchased and placed on the streets of the city for residents to use. After 2004, China began to introduce the bike-sharing model, and after 2017, bike-sharing developed rapidly in China, and companies such as ofo and Mobike also developed rapidly, but there were also a series of problems in the later period.

Online shopping was invented by the British in 1979, but with the development of the Internet, the scale of users of online shopping in China has been rising, and various online shopping platforms such as **, Tmall, Suning, and Jingdong have also appeared, and have also promoted the development of the logistics industry.

What are the new four inventions? One-minute animation knowledge popularization.

High-speed rail, Alipay, bike-sharing and online shopping have been called China's "new four major inventions".

1. High-speed rail. In March 2006, the CRH2A train, which was converted from the E2 series 1000, was loaded from the port of Kobe and departed for Qingdao, China, and some of the technology was transferred to China, thus opening the era of high-speed rail in China.

2. Scan the code to pay.

The QR code payment model is based on the concept of mobile payments, and the first payments made by mobile devices took place in Finland in 1997. Finntelem has launched a service to operate jukeboxes and drink vending machines by dialing a pay** number, which allows you to buy Coca-Cola at Helsinki Airport, according to local reports.

3. Bicycle sharing.

As early as 1965, the city of Amsterdam in the Netherlands put forward the "White Plan", according to which 50 bicycles were purchased and painted with white paint as markers scattered throughout the city for human use, which was the world's first unmanaged bike-sharing system, so the bike-sharing was invented by the Netherlands. In 2007, there was also a free bicycle travel in France, and it was only later that the Chinese popularity and innovative model were developed and promoted overseas.

4. Online shopping. Online shopping falls under the category of e-commerce. In 1979, Englishman Michael Aldrich invented the concept of online shopping. Aldrich uses a technique called videotex to connect a regular TV to a local retailer's computer via a ** cable.

By the 90s of the 20th century, after Amazon and eBay launched their ** in 1995, e-commerce began to gain popularity worldwide.

2.Chinese character laser phototypesetting technology.

3.Synthetic bovine insulin.

4.Compound artemether is the first drug with a new chemical structure discovered by China, which is of great significance to malaria, a highly contagious disease.

Gunpowder, printing, papermaking, compass.

The inventor of movable type printing Bi Sheng.

Gunpowder: Sun Simiao Bo was involved in the history of 100 schools of scholarship, mastered the Taoist scriptures and Buddhist scriptures, summarized the clinical theories before the Tang Dynasty, collected prescriptions, acupuncture and other contents, and compiled them into books such as "A Thousand Golden Prescriptions", which made great contributions to medicine and was respected by later generations"The King of Medicine"。He was not only a great pharmacist, but also a famous alchemist, self-proclaimed"Sun Zhenren"。

He summarized the experience of previous alchemists and collected the formulas of alchemists in the Heluo and Guanzhong regions, and finally proposed a more effective formula such as the sulfur fire method.

Papermaking: The inventor of papermaking - Cai Lun.

After Cai Lun, others continued to improve his methods. About eighty years after Cai Lun's death (the first year of the Eastern Han Dynasty), there was another papermaking expert named Zuo Bo. The paper he produces is uniform in thickness, fine in texture, and bright in color.

At that time, people called this kind of paper "Zuobo paper". It is a pity that the raw materials and manufacturing methods used by Zuobo have not been recorded in history.

The invention of the compass: The invention of the compass is the result of the working people of our country who have recognized the magnetism of objects in their long-term practice. As a result of productive labor, people came into contact with magnetite and began to understand the properties of magnetism.

The properties of magnet iron were first discovered. Later, the directivity of the magnet was discovered. After many experiments and research, a practical compass was finally invented.

Gunpowder was invented by ancient Chinese alchemists during the alchemy process.
