Scientific composition: Technology has changed life.
With the continuous development of science and technology, our living standard is as high as sesame blossoms, and our life is also rich and colorful. It can be said that technology has changed our lives.
A long time ago, people could only put a written letter in an envelope and let the postman deliver it to the recipient to convey the message. Now, the way of transmitting information has changed dramatically, and it can be easily realized by email or telephone. Thanks to modern communication tools, grandpa, who is now in his seventies, has a bright smile on his face all day. Look, he is using his mobile phone to invite his old friends to the park to play Tai Ji Chuan! Every time at this time, my grandfather will smile and say happily, "Now technology is developed, and even our elderly people use old-fashioned mobile phones!" " Yes, there are a large number of mobile phones for the elderly, and the sound is still very clear. As the saying goes, "seventy years old is rare", but now, even if you live to 80 years old, it is no longer rare. Look, grandma is also chatting with her cousin in Shenzhen on her mobile phone!
People used to cook with firewood, and the baked food tasted terrible and burnt, but now people use electric pressure cookers and microwave ovens. Look, grandma is already cooking with an electric pressure cooker! At this time, my grandmother said to me: "Now that technology is developed, the electric pressure cooker has been invented. This electric pressure cooker is really convenient! " "Yes, since our family has this pressure cooker, the cooking time has been shortened from the original 1 hour to tens of minutes, and the cooked food is delicious and fragrant!
Dad opened a company in Shenzhen as the boss and went abroad for business trips many times, but it took a long time to reach his destination, let alone do business, because of inconvenient transportation. But with the development of traffic and the opening of high-speed rail, it is very convenient for dad to do things now, from the original four or five hours to two or three hours, which is really convenient!
I am a loyal netizen, but don't get me wrong. I don't play computer often, but I often use the computer to check information, watch news, send emails and participate in online competitions. Unconsciously, my computer has become my "good friend". I remember, the teacher asked us to find out which one is "Three Sus", and I racked my brains, but I couldn't figure it out. Soon, I regarded the computer as a "good friend", so I immediately went online to look up information. It turned out to be Su Zhe, Su Shi and Su Xun in the Song Dynasty. I can't help secretly marveling at how many functions computers have!
Today, we are fortunate to grow up in a brand-new era. The flower of science has never been so brilliant as it is today. I believe that as long as we cultivate our love for science, develop good habits in the discipline and bravely climb the peak of science, our future life will be more colorful.
Science and technology composition: science and technology are by my side.
Time flies, with the changes of the times, technology also keeps pace with the times. The happy life of the people, the prosperity of the national cause, everything, are not all explaining the role of science and technology?
I can't help thinking of Eisenhower's words: "Science is a bit like the air you breathe. It is everywhere. " There is a high-definition TV set at home, a convenient and fast computer when going out, the car is flying at full speed, and the plane is flying slowly across the sky. Isn't that technology?
The prosperity of a country needs science and technology. With science and technology, we will strengthen the country and enrich the people, and the cause of the motherland will be more brilliant; On the contrary, it will only make the country decline and be suppressed by other countries until it dies. Isn't it? For the glory and glory of the motherland, we should study hard, discover, invent and create science and technology!
Recently, our school launched a demonstration activity of science and technology model. Rows of planes, towers and models are all made by students' skillful hands, which makes me think that maybe many scientists will invent countless advanced objects in the future.
Science and technology are also science, and they complement each other. Science leads to technology, and technology is technology. Science is continuous understanding, not only discovery but also invention!
Technology is everywhere, advanced and developed. Technology is like the nervous system of our time. What would the world be like if all science and technology disappeared? Some people are unemployed, wandering in the streets all day and doing nothing; Countries will also decline; The night is dark and silent as death.
Technology comes from life and reality. Perhaps, one day in the future, you will have a whim in a book, and after unremitting efforts and experiments, you will succeed. Perhaps, one day in the future, you will find a special substance in unintentional play. Technology is around you, depending on whether you are willing to reach out and grasp it.
Edison would not have invented the electric light, Madame Curie would not have discovered radium, and if he was not good at discovering life and was not keen on life, the steam engine would not have been born. Science is often the final success after thousands of failures!
"Science is infinite, it is an eternal mystery." I remembered this sentence of Einstein. Yes, the ocean of science is vast! It is a mystery, hidden in every corner of life, waiting for us to discover, discover and solve this mystery.
