What are the first in China s history and the first in the world in China

The earliest mathematical monograph in China (the world) that put forward the Pythagorean law: "Zhou Ji Sutra" (Western Han Dynasty) The oldest stone arch bridge in China (the world): Zhaozhou Bridge (Li Chun) Sui Dynasty) The first tea monograph in China (the world): "The Book of Tea" Lu Yu.

Tang Dynasty) China's (the world's) first pharmacopoeia: "Tang Materia Medica".

Tang Dynasty) The earliest engraving print with the exact date in China (the world): Xiantong "Diamond Sutra" (Tang Dynasty).

The first person in China (the world) to measure the length of the meridian: Monk and his party (Tang Dynasty) The first person in China (the world) to discover the geomagnetic declination: Shen Kuo. Northern Song Dynasty).

China's world's first are: quantum communication technology, high-speed rail technology, supercomputer technology, manned submersible technology, and China's Sky Eye.

Wait. 1. Quantum communication technology.

At 1:40 a.m. on August 16, 2016, the Micius Quantum Science Experiment Satellite was successfully launched on a Long March-2D carrier rocket in Jiuquan. The complete success of this launch mission marks another important step in China's space science research.

The leading quantum communication technology has achieved the world's most advanced status.

2. High-speed rail technology.

China has independent high-speed rail technology, which is mainly reflected in the independence of IGBT technology, the localization of high-speed train chips, and high-speed railways.

It is constructed by the national civil engineering central enterprises and the standardization of high-speed trains in China.

3. Supercomputer technology.

Tianhe-2 was developed by the National University of Defense Technology.

The supercomputer system developed by the company tops the list with excellent performance of petaflops per second at peak computing speed and petaflop operations per second at continuous computing speed.

4. Manned submersible technology.

The Jiaolong manned submersible is a manned submersible designed and integrated by China, and the Jiaolong manned submersible is in the South China Sea.

Several dives have been carried out, and the maximum depth of the dive has reached 7020 meters.

5. China Sky Eye.

500-meter aperture spherical radio telescope.

It is known as "China's Sky Eye". It is the world's largest single-aperture and most sensitive radio telescope led by the National Astronomical Observatories of the Chinese Academy of Sciences, with China's independent intellectual property rights.

After the founding of New China in 1949, the Chinese relied on their own strength to create many "firsts", realized changes from scratch, and displayed the ever-changing face of the motherland.

The first atomic bomb**.

On October 16, 1964, China successfully launched its first atomic bomb in the western region.

The first artificial satellite.

In April 1970, China's first artificial earth satellite "Dongfanghong 1" was successfully launched.

The first underground railway.

In October 1969, China's first underground railway, the Beijing Metro, was built, bringing convenience to people's lives.

The first Antarctic research station.

On February 15, 1985, the Chinese Antarctic Expedition built the Antarctic Great Wall Station on George Island.

The first high-tech agricultural base.

In February 1998, Beijing successfully established China's first high-tech agricultural base.

The first manned spacecraft.

On October 15, 2003, China's self-developed "Shenzhou 5" manned spacecraft was successfully launched, teaching China to send Yang Liwei, the source of Tianyuan, into space.

Today I am proud of China, and tomorrow China will be proud of me! This sentence is deeply imprinted in my heart. The Chinese have finally become one of the developed countries in the world by virtue of their ingenuity and hard work!

In 1986, Robert Temple, an expert in the history of science and technology in the UK, under the guidance of Professor Joseph Needham, researched, wrote and published a book entitled "China - The Country of Discovery and Invention", which pointed out that China does not only have "four major inventions", but has 100 "world firsts".
