Composition on the topic of technology

In real life or work and study, the most familiar thing to everyone is composition. Compositions can be divided into primary school compositions, middle school compositions, and college compositions (essays). I believe many people will find it difficult to write essays. The following are essays on technology topics that I have compiled. I hope they can help you. Essay on the topic of technology 1

In the era of black and white film, there were very few photos, so I cherish every one of them. Maybe you only have three photos in your life: childhood, graduation, and wedding. Nowadays, we have entered the digital age. There are more photos than you think about, and the memories of life have faded.

This can’t help but make me think: What has technology brought to us?

It is undeniable that technology has brought us convenience. When traveling, we can take out our cameras and take pictures of the beautiful scenery; when at parties, we can send group text messages and make many old friends; when we are away from home, we can make video calls to reassure our parents who are far away from home. Technology has brought us so much convenience, and we are connected to it and enjoy the benefits of technology.

When I read "Where can the hometown book reach, return to Yanluoyang", I felt how lucky we were, and we didn't have to be like the ancients for four years without being able to express it to our families. Is this really the case? Otherwise, we are unlucky. Because of the existence of technology, we cannot experience the homesickness of wanderers who can’t sleep at night. We cannot feel the pain of Liu Yong's "holding hands and looking into tearful eyes, speechless and choking". In our eyes, people who have been separated can still be connected. What we have lost is the humanistic feelings of the ancients. In this technological age, we cannot understand it.

Therefore, we deeply realize that technology is a double-edged sword. While it brings us convenience, it also reduces our humanistic sentiments.

Should we give up technology and feel the lost humanistic feelings? No, we will win in the trend of technological development and find our lost humanistic feelings. Technology is developing, human beings are progressing, and those who go downhill will eventually perish. In fact, we have long been aware of the shortcomings of technology and have taken many measures to remedy it. Bi Ru said that a well-known coffee shop has publicly stated that it does not provide wireless Internet service; there is also a bar that designs a wine glass that can only overflow when you sit next to it away from your mobile phone. The purpose of these small measures is to make people put down the digital products in their hands, truly devote their hearts to human interactions, regain their lost humanistic feelings, and no longer be "machine slaves".

Technology has brought us convenience, but we cannot let technology take away our humanistic feelings. Please put down your mobile phones and computers and engage in social networking, or send a letter to your parents in your hometown. Don't let "I send my sorrowful heart to the bright moon, and follow the wind until the night is over" become the last song! Composition on the topic of science and technology 2

"I'm dying of thirst! I'm dying of thirst" As soon as I entered the house, I shouted loudly. He picked up the water glass and drank it without saying a word. At this time, my peripheral vision was attracted by my sister at the table. She was carefully drawing a circle on a piece of white paper. The size of the circle was as big as the rim of the cup I was drinking water from. I suddenly thought: Can the paper be turned upside down on the cup without falling off? With this question in mind, I prepared to do this experiment with the mentality of giving it a try. Just do it, I prepared a cup with only half a cup of water and two pieces of white paper.

Experimental Step 1: I held a cup in one hand and a piece of white paper in the other, and various possible results emerged in my mind. After thinking carefully, I gently pressed the paper on the cup, covered the paper with one hand, and quickly turned the cup upside down. Wow! It worked! However, within a few seconds, the paper was like a child naughtily. I broke away from my mother's arms and was washed away by the water. What's going on? I thought about it again and again, and thought it might be because the water was not full. What would happen if I filled it with water?

Experimental step two: So, I filled it with water Full.

Experiment Step 3: Just like before, I pressed the paper on the cup and quickly turned the cup upside down. Wow! It worked again! This time I calmed down and counted silently in my mind: 1, 2, 3, 4, 5...

Ah! The paper was helplessly washed away again.

But compared to just now, this time is already far ahead. I smiled with satisfaction.

But what makes paper able to hold water? I couldn't figure it out, so I had to turn to the "wisdom heart" - the computer. It turns out that there is very little air dissolved in the water. The pressure of the air in the water on the cardboard is far less than the pressure of the atmospheric pressure outside the cup on the cardboard. The mass of the water itself is also very small, so the atmospheric pressure holds the water tightly like a powerful giant palm. It looks like it is held up by cardboard. But this only happens when the cup is filled with water. If the cup is not filled with water, there is enough gas in the cup to offset the atmospheric pressure outside the cup, so it cannot be dragged up. Even if it is held up, it will fall off quickly. So that's it, I finally understand.

Through this small paper holding water experiment, I discovered that there are actually mysteries of life everywhere in our lives. If I can have eyes that are good at discovery, I will definitely discover more in life. Beautiful phenomenon. We do not lack beauty, but we lack discovery. As long as we can observe carefully and feel with our hearts, I believe that we will be able to notice more extraordinary beauty! Essay on the topic of technology 3

When it comes to "technology", perhaps the first thing that comes to your mind is Rockets ascend to the sky, submarines enter the water, and cutting-edge technologies such as levitation trains, Shenba, and Tiangong-1 are used. In fact, technology is not far away from us: when the scorching sun arrives in summer, we can enjoy the coolness in a comfortable air-conditioned room; when we are hungry, my mother uses induction cookers, rice cookers, and microwave ovens to cook a table for us Delicious meals; when we have no time to take care of the pile of clothes that need to be changed because of study or work, the washing machine solves the problem for us... Look, technology is around us.

I came home from school on Friday and sat in front of the TV, listening to pop songs and watching Chinese and foreign news and anecdotes. It broadened my horizons, enriched my knowledge, and made me happy. Know the affairs of the world."

When visiting relatives and friends, electric vehicles, motorcycles and even increasingly popular cars show their infinite charm. It won’t take long before we can gather with our relatives and friends under the breeze.

When we travel, we either take a train and fly through the mountains to see the beauty of nature; we take a plane and soar in the vast sky, accompanied by blue sky and white clouds; we even sit on a maglev train. , feel the comfort of the wind and lightning. Technology is really amazing and has brought many conveniences to people.

The emergence of telephones and mobile phones has allowed us to say goodbye to the era of flying pigeons to deliver messages, and has enhanced communication between people. The popularization and use of computers not only brings people a way to get rich, but also solves many difficult problems in people's lives. It also eliminates the pain of missing relatives far away. This summer vacation, my family bought a computer. Through video, my grandma met my father who was working in Guangzhou. This made grandma extremely happy. She changed from her usual sluggishness and was cheerful all day long. Stop nagging and ask her father to come back and chat with her.

Even our rural schools use computers and multimedia equipment in class, which greatly improves our interest in learning.

……

Watt invented the steam engine, Edison invented the incandescent lamp, Franklin invented the lightning rod, Bell invented the telephone... It is the development of science and technology that leads the continuous development of human society. Move forward. Our great ancestors, after experiencing countless experiments, created many miracles for us. Today's science and technology is at its peak and has made great achievements in the fields of military, medicine, aviation and daily life. Cloning technology and nanotechnology are no longer unfamiliar.

We live in an era of science and technology, and we grow up in a life of science and technology. As the founders of the new century, we should set great ambitions and bravely climb the peak of science and technology. Looking forward to the future, the motherland will be a great place. In the near future, our lives will be made even better by science and technology.

Technology is not only around me, but also in my heart and in my swaying dreams.

Teachers and classmates:

Good morning!

On November 29, 2020, at the Fuzhou Science and Technology Museum, I participated in the 24th Fuzhou Youth Science and Technology Innovation Competition. I won the first place in the environmental science group and won the first place in the competition. Prizes. Here, I am particularly grateful to my instructors, Teacher Wu Ruiping and Teacher Xue Lian, who gave me careful guidance in this innovation competition. I would also like to thank my other teachers and classmates without whose support I would not have been able to succeed.

Now, let me briefly introduce the process and thoughts of participating in this innovation competition.

I am the propaganda cadre of the class, and I always publish the class’s blackboard newspaper. Whenever I finish writing a blackboard report with chalk, I always feel that the hands that touch the chalk are very dry. If I don’t clean them in time, my hands will peel off soon, which is extremely uncomfortable! Why do you feel this way? After inquiries, I learned that when human hands come into contact with chalk, the skin and mucous membranes will be irritated, causing the skin to become dry, rough, accompanied by itching, and even peeling. I developed a huge interest in chalk.

Observing chalk has become a required course for me every day: I found that there are often a large number of discarded chalk ends in the chalk trough in the classroom; I found that the teacher's body and hair were covered with white chalk powder; I found that chalk powder was flying in the air during class... It turns out that discarded chalk heads waste hundreds of millions of raw materials every year; it turns out that the harm of chalk powder to health and the environment is immeasurable; it turns out that my dear teacher is surrounded by chalk powder every day! So, I decided to transform chalk!

I communicated this idea with the instructors, and they were also very interested in it, so we started various attempts: wearing gloves in class? No, it’s inconvenient and inflexible; add a plastic sleeve behind the chalk for writing? No, it will still be wasteful; replace the chalk and blackboard with a whiteboard? No, the actual conditions do not allow it. We were stuck, but the brain never stopped thinking about transforming chalk. While making a scrapbook, I suddenly discovered that the colloid of the solid glue can expand and contract in and out as the shell device rotates. Human hands do not need to touch the colloid, as long as the shell is grasped, the pasting work can be completed. Swap the gel for chalk! I screamed with excitement. So, I did a big dissection of the entire solid glue - took it all apart. After careful observation, I found that as long as I find a solid glue shell device that matches the size of the chalk, I can fix the chalk like a solid glue colloid. live. In this way, I transformed into a rotating environmentally friendly chalk, which completely solved all the problems that once troubled me.

The creation of the rotating environmentally friendly chalk made me understand that scientific creativity comes from life. Only through more observation, more use of the brain, and more hands-on work can innovation be achieved. Students, pay attention to everything and learn from it! As long as you are a dedicated person, you can achieve success!

Thank you everyone! Essay 6 on the topic of science and technology

With the rapid development of modern science and technology, we have stepped out of the era of living like hair and drinking blood, and have come to the era of advanced science and technology. The development of science and technology has brought great convenience to our lives.

I used to worry that there was no light at night, but today every house is brightly lit. In the past, it was very luxurious to taste the delicacies of the sea, but now fish, meat, shrimp and meat are commonplace; in the past, I always felt that I was homely. It's hard to tell, but today we are as close as we are to each other. Yes, the series of benefits science has brought us cannot be ignored!

Concubine Yang Guifei of the Tang Dynasty wanted to eat fresh lychees, but fresh lychees could only be eaten in the south, so the emperor sent people on fast horses to transport them thousands of miles away. In order to ensure Fresh, how many fast horses have been exhausted! But now, if you want to eat fresh lychees, you can see them everywhere in the market, and they are a common meal on the tables of ordinary people. It can be seen how much convenience the development of science and technology brings to us!

In ancient times, wanderers who had left their hometown missed their relatives in their hometown very much because they had lived and worked abroad for a long time. They wrote a letter home, but after sending it, their family members never responded. Why? Because the letter may not have been sent to the family and was lost on the way; it may also take a long time before the family receives it. If you reply to another letter, it may take a month or two for the wanderer to receive it from the family. Therefore, it is difficult to say a word to relatives far away.

Now, you can send messages to your family members who are far away. The speed is very fast. The other party can know what you want to say in less than a second. Not only can you have a conversation, but you can also video chat. In this way, You can chat with your relatives far away at any time, and you can also see the appearance of your relatives far away. If you could meet your relatives far away in the past, what a happy thing it would be! Science and technology can definitely help you solve things that the people cannot solve. For example, if you encounter difficulties in learning, just turn on the computer and type, and the correct statement will be displayed on the computer screen. As long as there is science, there is no need to worry about any difficulties, no matter how big they are.

However, while science and technology are developing, environmental issues have been ignored. Discharging wastewater into rivers on a large scale prevents people from eating safe seafood and wastes precious resources on a large scale, but they never think about how serious the consequences will be. While science and technology are developing, the environment must also be protected.

Technology is a double-edged sword. It is the driving force for our progress as human beings. It brings us convenience and development, but it also brings many negative impacts. We must make full use of the benefits brought by technology, and we must not ignore the environment in which we live.
