Innovation is to create a feeling of the future.
Some time ago, my friends and I came to Sichuan Science and Technology Museum. In my opinion, this is my first visit to the Science and Technology Museum. Before I came here, I always thought that the science museum was full of boring scientific knowledge. Unexpectedly, it can be called an "amusement park" about science.
As soon as I entered, I saw many planes, all kinds of them, and I could fly them myself. Then, we came to a simulated space station, where we can experience astronauts riding bicycles and wearing gloves to do experiments in space, and we can also see what astronauts usually eat and use in spacecraft. In the exhibition hall on the first floor, there are also simulated rockets and hot air balloons. In a word, I really feel the development of China's space industry.
What impressed me the most was the acousto-optic hall on the second floor, which brought us a visual feast about electricity, and we could see with our own eyes the different situations produced by electricity under high voltage. With a loud noise, the performance began, fingertip discharge, rotating discharge and so on. "It's shocking. I feel that electricity can be so wonderful for the first time! " I can't help sighing. This gorgeous and spectacular high-voltage discharge not only brought us a strong visual impact, but also professional staff explained it to us one by one, which made us know a lot about electricity.
Later, I felt the close relationship between light and color through the prism; By turning the handwheel to make the generator generate current, I understand that the generator uses the principle of electromagnetic induction ... It can be said that all the knowledge in this exhibition hall is related to physics. I think learning physics through experiments will make knowledge more vivid and interesting!
The Science and Technology Museum is very big, with many exhibition halls. In addition to the above, I can also go to the virtual museum to experience the fun of VR, go to the Mathematical Mechanics Museum to experience the wonders of mathematics, and go to the Life and Science Exhibition Area to learn about life and self-help methods. ...
This visit to the Science and Technology Museum can be said to be an eye-opener. It turns out that science is everywhere around us, and science is not as boring as I thought. On the contrary, it makes me look forward to studying physical chemistry in the future. Our technology in China is changing with each passing day, and we can't help being proud of our motherland! I hope to visit the Science and Technology Museum again.
Innovation is the feeling of creating the future.
With the rapid development of modern science and technology, we have stepped out of the previous era of eating raw food and drinking blood and come to an era of advanced technology. The development of science and technology has brought great convenience to our life.
I used to worry that there would be no lights at night, but every household is brightly lit tonight; It used to be luxurious to taste the delicious food in the sea, but now fish and shrimp are commonplace; In the past, I always found it difficult to deliver letters from home, but now, heaven is still our neighbor ... yes, a series of benefits brought by science can not be ignored!
In the Tang Dynasty, Yang Guifei wanted to eat fresh litchi, but fresh litchi could only be eaten in the south, so the emperor sent someone to transport it from thousands of miles away with a fast horse. How many fast horses have been exhausted to ensure freshness! But nowadays, it is common for ordinary people to eat fresh litchi everywhere in the market. It can be seen that the development of science and technology has brought us much convenience!
In ancient times, homeless people missed their relatives in their hometown very much because they lived and worked far away from their hometown for a long time. After writing home letters, their families didn't reply ... why? Because the letter may have been lost halfway before it was delivered home; It is also possible that it took a long time for the family to receive the letter, and it may take a month or two for the wanderer to receive the reply from the family. So it is difficult to say a word to his distant relatives.
Now, you can send messages to your family far away, which is very fast. In less than a second, the other person can know what you want to say, not only the conversation, but also the video chat. In this way, you can chat with distant relatives at any time and see what they look like. How happy it would be if you ever met your relatives in the distance! Technology can help you solve things that people can't. For example, if you encounter difficulties in learning, as long as you turn on the computer to type, the correct sentence will be displayed on the computer display screen. As long as there is science, there is no need to worry about any major difficulties.
However, with the development of science and technology, environmental problems have been ignored. Discharging wastewater into rivers on a large scale makes people unable to eat safe seafood and wastes valuable resources on a large scale, but never thought about how serious the consequences will be. While developing science and technology, we should also protect the environment.
Science and technology is a double-edged sword, which is the driving force of our human progress. It has brought us convenience and development, but it has also brought many negative effects. We should make full use of the benefits brought by science and technology, and we can't ignore the environment on which we live.

Looking up, Beidou networking, fighters soaring; Bow your head, Long Qian is deep, and the rice is fragrant; Looking forward to the future, the country will be rich and the people will be safe, and the prosperity will be brilliant. Over the past 70 years, with the rapid development of science and technology, China, which is poor and weak, has already set foot on the dream of becoming a strong country and set sail.
Without the development of science and technology, it is impossible to realize the dream of a strong country. What is technology? Science and technology are the food in the hands of ordinary people, which can fill their stomachs; Technology is a variety of products in the factory, which can meet the needs of people's lives; Science and technology are the weapons of the army, which can protect their homes. Science and technology are the foundation of China's progress and rapid development.
Looking back, during the Opium War, the Qing government was corrupt and incompetent, and was unprepared for coastal defense. Hong Kong was occupied, its territory was occupied and its people were killed. People have no right to be slaughtered. The galaxy was investigated for no reason, the embassy was bombed, and people were angry but had nowhere to vent. Harassed by bandits' planes, but our air force only has backward J-8.
Without real strength, our humiliation will continue. It is the efforts of countless warriors. The breaking waves of Liaoning ships and Shandong ships are the roaring sky of J-20 fighters and the appearance of Dongfeng intercontinental missiles that shocked the world.
Without decades of hard work and struggle, how can we live a stable and peaceful life?
Technology has played a powerful dream. Chang 'e IV landed on the back of the moon for the first time in human history, realizing the dream of "flying to the moon" of generations of China people. The successful launch of the Long March V carrier rocket has made China's space technology ahead of the world. Snow Dragon 2 landed in Antarctica, leaving footprints of China people all over the world. The accelerated commercialization of 5G has enabled China to lead the world in communication technology. These fruitful achievements have inspired people, strengthened the country and inspired us to serve the motherland with science and technology.
The road to success will not be smooth sailing, and the road to a strong country through science and technology will inevitably encounter all kinds of difficulties and even the suppression of power. But our older generation of scientists and builders are not afraid of risks, are unknown, and are willing to give everything for the motherland. Countless young students in their prime are willing to devote their youth and blood to the motherland. It is they who make our technology change with each passing day, and it is they who make our country prosperous.
Looking back, grasping the past and the present, shouldering tomorrow, the nation will witness the rise of great powers; Seeing the present, the cause of rejuvenating the country through science and education is in full swing.
Being born is a good time for our generation to work hard. Let's cherish the present, study hard and set sail with the spring breeze of science and technology!

Turn on the computer, brush the webpage and check the mobile phone from time to time-this is the daily life of many city people. People linger in the traffic, enjoying all kinds of conveniences brought by modern life, and are also confused by complex personnel relations. Of course, at night, people will occasionally stop on the road to admire the bright moon and look for a few stars left in the night sky.
The modernization of life is an irresistible trend, perhaps because of the survival fear that human beings can't get rid of. Nature is great. She gave birth to human beings, provided them with food and environment for survival, but at the same time made them always look so small in front of her strength. Earthquakes, floods, droughts, rainstorms ... Humans constantly transform nature through science and technology, hoping to protect themselves. Science and technology not only help people face disasters, but also make people get rid of the shackles imposed by nature, which can make people cross the distance between time and space and make people's lives so colorful. Nowadays, we can learn knowledge from all over the world, master all kinds of information and deal with complex transoceanic work through computers. Our thoughts are no longer a book that can't be reached for several months, but an ordinary phone call, a simple video, or even a flight that just leaves.
However, such a fast and convenient life can easily make us think that we have grasped nature in our hands and we can do whatever we want with it. There seems to be nothing to be afraid of except the once-in-a-century earthquake, flood and tsunami. But even if we are lucky enough to avoid those great disasters, people should know that they have gone too far in the face of dirty air, dark sky, toxic daily food and frequent traffic cases. At this time, we will come back to cherish the beauty of nature. Unfortunately, most people's reaction is not how to improve their environmental awareness, but how to ensure their own safety and even find a beautiful "Xanadu" to spend their holidays. When everything seems at your fingertips, people become more and more indifferent to the world. I don't know whether this is progress or retrogression.
I don't want to deny modern life. If I have to leave this noisy and foggy life and herd sheep all my life, I admit that I have neither the ability nor the will. Technology is not the opposite of nature, it is just a tool. It is not science and technology that causes the environmental crisis at all, but the infinite expansion of human desire. That kind of desire is so strong that people forget to cherish and fear nature.
We often say, don't wait until it's completely lost to know regret. The increasingly abnormal climate has warned us. If human beings cannot balance themselves, they will eventually die. At that time, there was no need to think about what the most beautiful scenery looked like.

Over the years since the founding of New China, our life has undergone earth-shaking changes. Science and technology can be seen everywhere around us, which not only brings surprises to our lives, but also brings convenience to our lives.
The birth of WeChat makes people's lives more convenient. The earliest contact was by telegram, letter, and later by telephone, but endless topics and high telephone charges always made people feel distressed. Now, you can directly open the video, and the distance between relatives and friends in Wan Li is no longer an obstacle to communication.
Wechat not only brings convenience to communication, but also liberates wallets. Once I saw that my mother had no money to buy food, so I took the money and shouted, "Mom, you forgot to bring money." Mom shook her mobile phone and said, "Baby, I can pay by WeChat". It suddenly dawned on me that my mother had a "carry-on wallet". Even my grandparents learned to use WeChat, and they also learned to use WeChat red packets during the New Year. Wechat has brought a lot of laughter to our family.
Do you think WeChat is a good thing?
In life, not only WeChat is easy to use, but cycling is also a good thing to enjoy. Rows of "minions" stand straight like soldiers and become a beautiful landscape. You can see it in every street and alley. Because it is environmentally friendly and saves money, you can ride just by scanning the QR code to pay, which has become the object of touting.
There are many high technologies that we have never seen before. Wechat and bike-sharing are just the tip of the iceberg. I believe that the continuous development of science and technology will make our life happier and our motherland stronger!
Innovation is to create a feeling of the future.
When you play happily with friends, when you get together with your family to enjoy the warmth of home, and when you sit in a classroom with bright windows and are eager to learn, do you think these happy moments are hard-won? Do you know who is quietly paying behind the scenes?
It is the uncles of the People's Liberation Army who have a peaceful, stable and prosperous environment in the frontier. All-weather training, every movement must be accurate and the task must be completed. Sometimes you even risk your life. Can you do this for decades? It is because of them that we have a strong country, and strengthening the army through science and technology is their tenacious sword to defend the motherland!
Facing the call of the sea, in 20 12, China's first aircraft carrier, the Liaoning, entered China's navy, and China ended the history of five major countries without aircraft carriers. The aircraft carrier has been in the water for a century, and it is desperate for the country to show its military strength. 12, 17 This year, China's first self-built domestic aircraft carrier, Shandong Ship, was officially launched, marking a major step in China's aircraft carrier industry, which excited the whole country and amazed the world, fully demonstrating the confidence of a maritime power to the world. Power through science and technology is no longer a slogan, but the world appearance of scientific and technological achievements.
Remember the success of Shenzhou 5's manned space flight? China became the third country with this technology. Do you still remember the first successful landing on the back of the moon on behalf of all mankind by Chang 'e IV? China is no longer a country at the mercy of others. 20 19 China Long March V carrier rocket was successfully launched, Xuelong II made its maiden voyage to the South Pole, the commercial launch of 5G accelerated, and Phoenix spread its wings at Beijing Daxing International Airport. These major scientific and technological events have demonstrated the extraordinary China style and the strength of China. Today, China is a brand-new technological power. On the journey of China's development, we have seen the future and hope.
It is the dream of everyone in China to become a powerful country through science and technology. No matter how difficult it is, let's go forward for our patriotism. The most important thing is to be stable and far-reaching, and the most important thing is to be a strong country through science and technology, not for anything else, but for the future of China!
Innovation is to create a sense of the future.
Whenever I see a passenger plane soaring in the air; Whenever we see the successful test flight of Russian and American new fighters; Whenever I watch aviation war movies, I feel a little excited in my heart. My ideal is to be able to build the most advanced fighter in the world.
You ask me why I have such a dream, because China is relatively backward in military and science and technology, and has a certain gap with advanced countries such as the United States. Therefore, I want to be such a scientist and try to catch up with developed countries.
China used to be the most developed and richest country in the world, but in the Ming and Qing Dynasties, because we didn't pay attention to the development of science and technology, when other countries developed rapidly, we were still standing still. So, they invaded our territory and plundered our wealth. Therefore, we must wake up and be strong.
The prosperity of a country must be backed by a strong military force, so that the people can develop their economy in a peaceful environment and the country can become richer.
We all know that "technology is the primary productive force", and what we are learning now is to lay the foundation for improving the level of industrial manufacturing. Nowadays, the mobile phones and cars we use reflect the influence of technology on our lives. I also want to change our lives with advanced technology.
In order to realize this dream, I must study hard, ask for advice modestly and be brave in innovation. Einstein once said, "Success is one percent inspiration and ninety-nine percent perspiration". Only by maintaining the belief of diligent study can we lay a solid foundation for realizing our ideals and prepare for realizing higher dreams in the future.
China is waiting for a new round of "talent rise". We should not be confused by the interests of other countries, but should think that only when the country is strong can our nation be strong. We should have a sense of responsibility that "the rise and fall of the world is our responsibility". The country needs us to master a new generation of high technology in order to truly realize the dream of strengthening the country through science and technology!
