My 1982

Li Zhongxin was in the restaurant on the river, and it was a cup of tea. He also got a small western dining, and he was very casual and versatile. The old objects left in those foreigners.

At this time, there are very few people who drink afternoon tea on the riverside restaurant. Li Zhongxin looked at those old objects, and the face gradually became down.

Li Zhongxin reads, the more I think, those old objects represent the continuous progress of science and technology in foreign developed countries, representing the world's continuous progress, and China is stagnant at that time, so, Li Zhongxin I feel some small depression.

Say this! Li Zhongxin has always known that China has a history of civilization and technology in China, has been in the world's leading level.

The Science and Technology Activities of the Chinese nation have a long history, and have made great contributions to human development, and they have been in the center of the world's science and technology stage in the mid-sixteenth century.

At the earliest time, China's Oracle has a record of the eclipse, this is the world's earliest eclipse record.

In the Warring States Period, China has a book of "Examination". This book has accurately records the six different ingredients of copper-tin alloy and its different purposes. It can be said that the discovery is very cattle. A piece of grade forced.

During the Western Han Dynasty, the Chinese invented papermaking, Chinese scientists Cai Lun improved and improved paper technology, so that paper technology quickly promoted in China, and paper can be said to be a great scientific process, change people civilization. Development progress.

In this way, the birth of paper is an important milestone in human history, and it is a great revolution in the history of human dissemination.

Before the first piece of paper, human beings did not tried other communication media, China's simple, , Egypt's papyrus, Europe's sheepscript, have posted a place in the history of human dissemination.

However, when the paper appears, they have a very fast to withdraw from the historical stage, so that the paper is located in the paper.

Why is this this? Because, they bring greater inconvenience to humans while bringing the communication and writing.

For the simplest example, in ancient China, if someone wants to write a book, you have to cut the whole bamboo forest to write materials, a book needs a bamboo forest, then if it is ten books, then How much bamboo forest is needed.

How can this book be transmitted in the crowd?

At that time, an official's daily official document, at least 55 kilograms per day, can be said to move those documents from the ground to the table, and then repeat these actions, you need to repeat many times a day.

Similarly, it is precisely more than 300 sheepskins, which is produced by the Bible, is because of these reasons, these things are unable to undertake historical reunions that record civilization and inheritance civilization.

For thousands of years, human beings have supported this hopes in the darkness of civilization and knowledge, until the paper is born, this is the shackles of the ban, the shackles of human civilization, civilization and knowledge snowflakes on one night There are every corner of the world.

It can also be in this way, the invention of paper and typography is another great revolution - the cultural rejuvenation laid a solid material foundation.

The general performance of literary revival is the rise in science, literature, and art, with the aim of adapting to the interests and requirements of emerging bourgeois in cultural interests, making human knowledge and better development.

However, in the Middle Age Europe, abstinence and religious rule, theology and academic monopoly cultural fields are in the field of medieval, the whole Europe is in the darkness of the medieval. The root cause is due to the restriction of writing materials and typography, the dissemination of cultural information is extremely Difficulties, the people are in obscurity and are willing to rule ..

Not the people don't want to close the scientific knowledge, learn scientific knowledge, but there is no chance, just like the "Bible" that we have talked before, it takes 300 sheepskin, the price is unable to imagine and Accepted.

Because of such a case,, at that time, only a very small number of monks can read the words, in order to be higher education, civilians have no opportunities, the same literary revival is also no chance.

Until China's papermaking and orthodontics, the possibility of substances was provided for literary rejuvenation.

After that, the Chinese invented the porcelain. The famous "Silk Road" communication has communicated the exchange of Chinese and foreign cultures. China has gradually be known as "silk country", accompanied by the export of China Porcelain, China has begun to "China" Enjoy the world.

China ceramics began to output out, and later, Tang Dynasty, five generations to the early Song Dynasty, reached a climax. At this stage, the ceramic variety has Tang Sangca, Xing kiln (including fixed kiln) white porcelain, Yue kiln ceramic, Changsha kiln painted porcelain and olive glaze ceramics (that is, the bowl of kiln in Guangdong) and a bowl of storage container) .

The output area and the country have northwestern North Korea and Japan; Southeast Asia, Singapore, Thailand, Malaysia, Indonesia, Philippines; South Asia, Sri Lanka, Pakistan, Iraq, Saudi Arabia, Oman; North Africa; Eastern Kenya and Tanzania.

At that time, there are two main routes from the maritime traffic route. First, from Yangzhou or Mingzhou (now Ningbo), North Korea or direct Japan's route; the second is from Guangzhou, to Southeast Asia, or from the Strait of the Malacca, enter the Indian Ocean, Sri Lanka , India, Pakistan to the route of the Persian Bay.

After this technology, it gradually passed to Persia, which was passed from Arab to Italy and the whole Europe.

To the Tang Dynasty, Chinese scientists invented the gunpowder and the first time it was used in war. In the Song Dynasty, the compass and ivered printing technology invented by Chinese scientists have been widely used.

Later, the "Materia Medica" of Li Shizhen in Chinese Medicine Beng became a collection of Chinese medical development, which can be said that it is countless.

At this time, the development of ancient Chinese science has reached the peak period, and all kinds of technology have been mounted on the historical stage.

Li Zhongxin has been clear that China has maintained a scientific knowledge of the scientific knowledge of the West, and many inventions apps used in modern Western worlds come from China. China is the country of inventions.

However, due to the end of the Ming Dynasty, China implemented the "closed door" policy for foreign ministers, which affected modern science and technology in the spread and development of ä countries, and Ä was in relative stagnation.

At the same time, Europe has become the birthplace of modern science, the productivity is rapid, and the scientific technology has been rapidly advanced. China has gradually launched the distance from the world's advanced countries.
