Major scientific and technological achievements such as "two bombs and one satellite", hybrid rice, manned spaceflight, deep-sea exploration, C919 large aircraft, and Sky Eye Telescope are inspiring. The Qinghai-Tibet Railway, the Three Gorges There are frequent good news about national projects such as the South-to-North Water Diversion Project, the West-to-East Gas Pipeline, and the Hong Kong-Zhuhai-Macao Bridge. High-speed rail, mobile payment, the sharing economy, and online shopping are leading the trend. But, do you know? These great achievements are inseparable from the help of technology.

- said: "Now we are closer to realizing the goal of the great rejuvenation of the Chinese nation than at any time in history. We are more confident and capable of achieving this goal than at any time in history." This is all thanks to due to the rapid development of science and technology. On October 1, 2019, a grand military parade ceremony was held in Tiananmen Square. Throughout the military parade, China had 47 ground formations, 12 air echelons and 32 equipment formations. Among the various weapons displayed by the equipment formation, 40% are making their debut and are all made in China. It can be seen that China's science and technology is developing rapidly.

The development of science and technology has transformed China's "millet plus rifle" in the Korean War into the current "rocket plus missile", making China no longer subject to aggression by other countries. After many years of ups and downs, the Chinese can finally live peacefully! It can be seen that technology and human beings complement each other. Without technology, the quality of human life would be very poor and very unsafe. However, without humans, technology and technology would not have appeared on earth. Therefore, while we enjoy the convenience that technology brings to us, we must also shoulder the responsibility of researching and developing new technologies.

In the past 71 years, China's science and technology has improved significantly. But those scientists are still not satisfied. They still spend every day in the laboratory, researching possible breakthroughs in technical problems, and dedicating their lives to China. We must also have such a spirit and be willing to dedicate ourselves to China.

The development of science and technology cannot be separated from the promotion of human beings. Throughout the ages, how many scientists have devoted themselves to one problem after another. They have been working for more than ten years, or even for decades. The purpose is for China to become stronger and avoid being bullied. Their perseverance paid off: as each problem was overcome, New China became increasingly stronger. Now, China has shifted from passive defense to active offense. Significant achievements have also been made in science and technology.

"The prosperity of science and technology will make the nation prosper; strong science and technology will make the nation strong" has also become the "mantra" of everyone in New China.

Last summer, I visited Xi’an No. 9 Space City.

As soon as you enter the door, you will be dazzled by the numerous models of planets, rockets and satellites. Suddenly, I had infinite curiosity and fantasy about the universe. As I walked inside, the lights gradually dimmed, and there were many bright stars in the sky, making me feel as if I was really walking in space. Then, walking into a room, a huge satellite detector model came into view. Next to it were China's earliest manned rocket spacecraft "Shenzhou 1" and the most advanced rocket spacecraft "Shenzhou 13". They were surrounded by stars. The moon and earth surround the satellite of David. It turns out that our country has achieved so many aerospace achievements in the past 50 years. These achievements were obtained by the aerospace heroes at the expense of their youth and precious lives. I couldn't help but feel awe for them. When young people are strong, the country will be strong. As a teenager, my dream of aerospace was born spontaneously.

In order to light up the space dream in my heart, I then experienced the space simulation project.

Moonwalk. This project is to simulate astronauts walking on the lunar surface. They tie a rope on a higher platform. The rope is very elastic and can simulate a weightless environment. They also walk on a sponge because the sponge layer is low and the rope is elastic. You have to fall down hard enough to walk, which is very difficult. We are already struggling to walk in our own clothes. Just imagine how difficult it is for astronauts to wear spacesuits that are many times heavier than our clothes and complete their tasks. Becoming an astronaut is not an easy task, and you must have a hard-working spirit.

Then, I went to experience the project of returning to Earth. This project is to experience the process of astronauts returning to Earth in a return capsule. I walked into the VR room, put on VR glasses, and the chair kept rotating and shaking. Directly below is the Earth. As it gets closer and closer to the Earth, the bottom of the return capsule is accelerated and rubbed by the impact force of the atmosphere, and it turns red as if it is on fire. By the time it was over, my legs were weak and my head was spinning. Astronauts have to literally fall from an altitude of 10,000 meters and endure indescribable discomfort. To be an astronaut, you must also have a spirit of dedication and sacrifice.

After the experience was over, my mood could not be calm for a long time, and I had a clearer direction for my space dream.

I must strengthen physical exercise and have a strong body; secondly, I must work harder to learn cultural knowledge. Only through my own efforts can I step closer to my aerospace dream and contribute to the aerospace industry of the motherland. Come on!

At that time, the environment at home and abroad was very severe, and amidst the turmoil, our party led the people to go through all the obstacles and overcome many difficulties, and finally established the People's Republic of China on October 1, 1949.

After the founding of the People's Republic of China, China, the sleeping lion of the East, began to slowly wake up. Industry, agriculture and other fields are developing rapidly. Among them, the development of science and technology is particularly eye-catching.

In 1964, China's first atomic bomb successfully exploded in Lop Nur, Xinjiang, indicating that our country had reached a very high level in terms of atomic bomb theory, structural design, and the design and manufacturing of detonation control systems.

In 1965, a team of Chinese scientists synthesized bovine insulin, a biologically active protein for the first time. The success of this experiment not only caused a sensation in China, but also changed the international attitude towards China. . Because this is a major breakthrough in human biological science and a big step for mankind to understand life and uncover the mysteries of life.

In 1966, Chen Jingrun, a young Chinese mathematician, used a large amount of manuscript paper to calculate by hand in a difficult research environment, and successfully proved Goldbach's conjecture, one of the three major mathematical problems in modern times.

In 1970, China launched its first artificial satellite, Dongfanghong-1, making our country the fifth country in the world to independently develop and launch artificial earth satellites.

In 1973, Yuan Longping used genetic diversity to breed hybrid rice "Nanyou No. 2" and developed a complete set of seed production technologies. After the large-scale promotion of "Nanyou No. 2", the country's total grain output has increased significantly, allowing our country to solve the food problem of 22% of the world's population with less than 10% of the world's arable land.

…

These are the results of the unremitting efforts of the Chinese people led by the Communist Party of China.

-Zeng said: "If China wants to be strong and rejuvenated, it must vigorously develop science and technology and strive to become the world's major science center and innovation highland. We are closer to the great rejuvenation of the Chinese nation than at any time in history. As a goal, we need to build a world science and technology power more than any time in history!"

What impressed me most was the explanation of the coloring process of "A Thousand Miles of Rivers and Mountains". It was relying on the large screen to restore the display layer by layer, which gave me some intuitive understanding of the painting techniques at that time, and also made me more knowledgeable. Marvel at the author's wisdom.

Due to time and environmental influences, cultural relics undergo physical and chemical reactions and are damaged to varying degrees. Cultural relic restoration masters will use high-tech instruments such as high-power optical magnifiers and ultrasonic cleaners to make the restoration of cultural relics more convenient, and then use their Hands bring treasure to life.

I really like these national treasures and the stories behind them. I feel full of pride every time I watch them. With the further development of science and technology, I believe that more treasures will be discovered and more history and culture will be waiting for us to explore.

I hope that when I grow up, I can become one of them and take our treasures from ancient times home, let their lives bloom again, let the world know China again and see China!

Our motherland is so powerful and I am deeply proud of it.
