The world s scientific and technological development and progress in the past decade are briefly des

1. Optoelectronic information industry, 2. Software industry, 3. Intelligent machinery industry.

China's scientific and technological achievements in the 21st century include manned spaceflight, Jiaolong's exploration of the deep sea, single-aperture radio telescopes, and quantum science experiment satellites. The Quantum Science Experiment Satellite, Micius, has opened the door to global quantum communications, space quantum physics, and quantum gravity experiments.

In the 21st century, in addition to the above scientific and technological achievements, China also has supercomputers, third-generation nuclear power technology, Beidou satellite navigation system, domestic large aircraft C919, unmanned driving, 3D printing, face payment, smart home, etc.

The Single-aperture Radio Telescope, abbreviated as FAST, full name 500-meter aperture spherical radio telescope, has created a new model for building giant telescopes, with independent intellectual property rights, and is considered to maintain world-class status in the next 10 to 20 years.

Jiaolong manned submersible is a manned submersible designed and integrated by China, which has carried out many diving missions in the South China Sea, with a maximum diving depth of 7,020 meters, ranking among the best manned submersibles in the world.

There is much to remember about the past century, many of which have changed our lives dramatically, and the predictions of thinkers have often come true.

The American scientist Benjamin Franklin once said: In the future, human knowledge will increase greatly, and new inventions that we cannot think of today will appear again and again, and I sometimes almost regret that I was born too early, so that I could not know what new things will appear. He was right.

In the past 100 years, human science and technology can only be described by leaps and bounds, if an inventor in 1900 looks at today's world, he will recognize cars, **, airplanes, he can also imagine spaceships, deep-sea submarines, but he will definitely know nothing about computers, the Internet, genetic engineering, nuclear energy.

Now, knowledge has given mankind unprecedented self-confidence and optimism, and one writer wrote: "I sincerely believe that we live in the greatest age of knowledge in human history, and there is nothing we do not understand", "As long as people can think of things, there are always people who can do it." The development of technology in the 20th century has made this statement more and more like the truth.

The progress of science and technology has completely changed the way of human existence, and it has also changed the direction of human thinking. In the next 10 to 20 years, there is no doubt that science and technology will make breakthroughs and expansions in many fields.

Maybe the human brain and the computer can be integrated, maybe we can settle on Mars, maybe everyone can clone spare organs, maybe we can review the scientific and technological inventions that brought great changes to human life in the 20th century, look forward to the future development trend of science and technology, and enter a new era of knowledge economy.

Nearly 100 years of scientific and technological development:

Major breakthroughs have been made in the development of methanol to low carbon olefins technology and industrial testing.

A major breakthrough has been made in the industrial pilot project of "Methanol to Low Carbon Olefins (DMTO) Technology Development", which was cooperated by the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences, Shaanxi Xinxing Coal Chemical Technology Development Co., Ltd. and Sinopec Luoyang Petrochemical Engineering Co., Ltd.

Nearly 100 methanol conversion, ethylene selectivity, propylene selectivity, and low carbon olefins (ethylene, propylene, butylene) selectivity of more than 90 percent were achieved on an industrial test plant with a daily processing capacity of 50 tons of methanol. The successful operation of the pilot plant is of great economic and strategic significance to China's comprehensive utilization of energy and the diversification of low carbon olefin raw materials.
