Science refers to the application of universal truths or theorems that have been discovered, accumulated and recognized, as well as systematic and formulaic knowledge. There are many different explanations about the definition of science: Ci Hai (version 1999): "Science: a knowledge system that uses categories, theorems, laws and other thinking forms to reflect the essential laws of various phenomena in the real world.
French Encyclopedia: "Science is different from common sense at first, and science seeks order in things through classification. In addition, science tries to explain things by revealing the laws that govern things. "
Encyclopedia of the former Soviet Union: "Science is the category of human activities, and its function is to summarize and systematize the knowledge about the objective world. The concept of' science' itself includes not only the activities of acquiring new knowledge, but also the results of such activities. "
Introduction to modern science and technology: "It can be simply said that science is systematic knowledge that truthfully reflects the internal laws of objective things." Classification of science: according to different research objects, it can be divided into natural science, social science and thinking science, as well as philosophy and mathematics that generalize and run through the three fields; According to the different connection with practice, it can be divided into theoretical science, technical science and applied science. According to the direct degree of human utilization of natural laws, science can be divided into natural science and experimental science; According to whether it is suitable for human goals, science can be divided into broad science and narrow science.
Each classification can be divided into many branches. For example, the branches of natural science include space science, earth science, environmental science, life science, life science and physics. The branches of social science are anthropology, economics, psychology and geography.
There is a magazine about science that I like very much. It's called we love science. This magazine belongs to China Children's Press and Publication Corporation, and it is the only national popular science journal for children in China. Our magazine is a good partner of primary school students and junior high school students, providing readers aged 5- 18 with rich news information and high-quality spiritual food, providing fast, comprehensive and high-quality services for hundreds of millions of children and making new contributions to their healthy growth.
It covers more than 20 columns, such as life reverie, hot spot tracking, holographic exploration, science speedboat, cosmic mystery, juvenile military academy, earth guardian, cute animals, science adventure camp, animal SOS, water world, science around us, happy science class, computer gamers, theme parks, eye-opening, story magic disc, cool play street, hands-on DTY, Koman amusement park and so on. I often read the magazine "We Love Science", which not only makes me understand a lot of scientific knowledge, but also enriches my life and makes me happier.
I summed up the characteristics of this magazine: "the most unexpected", "the most adventurous", "the most intelligent" and "the most interesting". I especially like it.
We love science because of its great function. Science and technology are the primary productive forces.
Science can promote the development of social productive forces. The transformation of science into social productive forces requires certain conditions, that is, making full use of science to serve social practice.
To fully apply science, we need to know science, deeply understand science and constantly improve the level of science and technology. We love science because it is so profound and mysterious.
Such as: exploring the mysteries of nature; Explore the mysteries of the biological world; Explore the mysteries of space, and so on. We love science because it can change and improve our work, production and life.
We love science, because science education can revitalize the country and the nation.
2. Write a composition on the topic "We love science". We all love science about 600 words. Science is not only a branch of the knowledge system that reflects the objective laws of nature and society, but also a powerful force for the development of the country and mankind.
I heard the teacher say the word "science" when I was a child. I didn't understand its meaning at that time. All I know is that I can't suck my fingers because I have bugs in my hands. You have to take an injection and take medicine when you eat. When I entered primary school, I met some great scientists, such as Galileo, Einstein and Qian Xuesen ... At that time, I had a reverence for scientists and a desire to study science.
Now, I am a seventh-grade student. I am on the great ship Discovery, sailing in the ocean of scientific knowledge: from creatures, animals to plants, from the solar system, the Milky Way to the boundless universe, we find the truth through study, experiment and observation. Looking through the thick history, I saw a series of horrible historical fragments, and my thoughts were taken to the dark old China.
More than a hundred years ago, foreign powers made foreign guns with gunpowder invented by our ancestors and slaughtered countless Chinese children; More than 70 years ago, Japanese imperialism ravaged the land of Jiuzhou, wantonly implemented the "Three Lights" policy, and killed many people in China ... Looking back at the history of blood and tears, let us always remember that if the country wants to be strong, science and technology develop, it will be beaten if it falls behind. Look! After the founding of New China, the country became increasingly prosperous, science and technology developed gradually, and China was taking off.
From China's restoration of the legal status of the United Nations to China's accession to the World Trade Organization, from China's successful development of "two bombs and one satellite" to the successful realization of manned space flight, these marks China's great achievements in politics, economy and military affairs, and are brilliant achievements of China people's unremitting self-improvement and scientific and technological development. China has really risen! Chinese people are proud of this.
Science benefits mankind and science benefits the future. As the successors of the motherland's construction, the future of science lies with us, and we have a long way to go.
We suck the South Lake water, remember the teacher's inculcation, explore knowledge under the cold window and study hard. "Let's stand on the shoulders of scientific giants, uncover more scientific mysteries and create more brilliant scientific and technological civilization!" .
3. We love science-based composition and are not ashamed of mediocrity ... "I read the book How Steel was Tempered, How People Should Live, etc. on the Internet during the summer vacation.
However, life belongs to everyone only once. In fact, there are no natural heroes in this world. Paul can be a hero because of his own efforts-on the battlefield of war! Out of nothing, "iron" becomes "steel". In this case, he still insisted on writing books and reading How Steel was Tempered. Recently, I watched How Steel was Tempered. His mother washed and cooked for others, and he was paralyzed. However, Paul's resolute face seems to be in front of my eyes, and life is like steelmaking. Kochakin's growth and fate are ups and downs.
Savor this book carefully: "The sword front comes from sharpening, and the plum blossom fragrance comes from bitter cold." Compared with Paul? "Finished reading this book! Some people say that Paul is a born hero and tastes Paul's spirit.
I feel more and more that we should learn from Paul's spirit, strengthen our ideals and beliefs, grow up, love life, enrich ourselves and meet a better tomorrow. Today's society is an information society with fierce competition, and the knowledge economy has begun to take shape.
From the perspective of the international community, peace and development have become the theme of the times, and the international competition around economy and science and technology is becoming increasingly fierce. Facing the unbearable labor intensity and hunger and cold of ordinary people, he did not fall down; In case of blindness and illness, it is of great significance. For the prosperity of our great motherland, let's follow Paul's example, practice life and embrace the future optimistically. He finally succeeded in writing the book How Steel was Tempered.
I read, read. Good things should be taught, and a correct world outlook, outlook on life and values should be established.
I remember a famous saying in the book. Compared with ordinary people, he has to pay twice the price for writing one more word.
So how is steel made? I believe there will be a fiery steelmaking scene in everyone's mind. Actually! "People's most precious life, we have no choice, through the ups and downs of knowledge and great men, are honed in the burning flame.
Life can be said to be a tortuous road. In the journey of life, you will encounter many difficulties, and you will face the blow of failure and the pain of not being understood. All this is short-lived.
After breaking through obstacles and overcoming difficulties, looking back at the road we have traveled, we will find that it is the flame that sharpens life. How many heroes: "Human life is the most precious."
When he looks back on the past, he should not regret his mediocrity ... almost no one wants to live a mediocre life. However, the road behind him is more bumpy: Paul grew up in bitter water and lost his father in his early years.
Soon, Paul was blind and didn't care about himself. With a correct goal in life, he will not be dragged down and humiliated by life, because even the grass is trying to add a little green to spring and create excellent quality. He hopes to leave his figure on the colorful picture scroll of the spring return to the earth, and not be drowned by misfortune, so that he will be strong in the raging flame of suffering. He worked in the canteen for two years. But not everyone can make good steel. As people often say, in the face of the relentless blow of lost manuscripts and the continuous deterioration of health, he still did not give in and went forward bravely! The bell of 2 1 century is about to ring. We stand on the threshold of the new century, looking for the heroic complex of the past and reshaping the "Paul spirit". There is only one way-training.
The country needs profound knowledge and strong will. His mother sent him to the station canteen to do odd jobs, and his brother was an ordinary worker. When Paul 12 years old, I had the perfect answer to this question.
This book is mainly about him. Facing the test of life and death, he didn't flinch. With persistent pursuit, I finally grew from a poor teenager to a fighter with lofty ideals, noble character and tenacious style on the construction site of heavy wind and blizzard. One's life should be spent like this, looking back, being decisive and daring to innovate.
So the difficulties we encounter in our study and life are really insignificant. What reason do we have to sigh and shrink back? Only when a person sets up lofty ideals can all countries concentrate on seizing the commanding heights of development in the 2 1 century, which makes China face new opportunities and challenges. The pace of China's "catching up with the times" is accelerating, which makes our Chinese nation face the opportunities and challenges of all-round rejuvenation, and we are deeply touched.
Is it the mood when reading with Paul? You shouldn't waste time regretting, an ordinary soldier.
How to write the composition with the theme of "We love science" requires 500 to 600 words. In 2 1 century, science will become human life.
If you don't know science, you can't survive in this society. If you have a seed of science and cultivate it carefully, it will take root, sprout and bear countless fruits over time ... The Nobel Prize in Science is an award that inspires people to love science and create our better life with science.
Nearly 500 scientists from more than 20 countries won the Nobel Prize. When they walk to the podium of the Nobel Prize, they represent that they have great wealth created by science. Therefore, we should study science, love science and show science.
But how can we do it? Scientists tell us that curiosity is one of the most important aspects of human nature and the main driving force for exploring scientific mysteries; The best way to satisfy this strong desire is to have the courage to ask why, to try and innovate, to overthrow the previous words and conclusions, and finally to get your own results. For example, Galileo, Copernicus and others bravely pointed out the wrong arguments of their predecessors regardless of pressure and opposition from all sides.
Through personal practice and experiments, I proved that my point of view was correct and gained my own success. I heard that there are three senior one students in a middle school, and they are also very curious.
They are full of curiosity about the national musical instrument CuO. After analyzing the characteristics of this instrument, they decided to make a musical instrument similar to "Wrong". They go to pick up or buy a lot of straws every day. They study carefully, take advantage of countless breaks and experience countless failures.
As the saying goes, "failure is the mother of success" is not wrong at all. They finally succeeded. 65,438+0,000 straws are inserted together to form a huge straw instrument, which sounds as beautiful and euphemistic as its sound, even better than the sound of "Fu". Although they are not great scientists, it is not easy for them to think of such things and overcome many difficulties to do them.
Think about myself, I have tried the taste of success. Seeing others playing with airplane models before, curiosity drove me to have a new desire to be a model, so I kept collecting materials and then made them myself. Although I hurt my hand, shed blood and left a scar in the process of doing it, I finally succeeded in making a beautiful model plane.
At that time, my happy expression had forgotten all the pain and suffering in the process of doing it. This is the curiosity of our teenagers. What teenagers can think of, adults may not think of, because teenagers' fantasies are naive and strange.
In fact, the innate conditions of Nobel Prize winners are not as good as ours. Why can't we do what they can? Young friends, seize our precious youth! Use your head and do it! The power of science is infinite, and it will bring you unexpected wealth. Therefore, we should love science, but if we don't dig the mystery of science and practice it, we will never get the happiness of science.
Some people only know one thing and don't know another. How can they succeed if they only understand the surface and don't explore deeply? Science is like an ocean ten thousand times bigger than the universe. We are like some fish. Although we swim freely today, there will be no oxygen in the water tomorrow, so we have to change places. This ocean will be polluted by us. At this time, we will look for another ocean. This is the new science we are looking for. Only by constantly updating can we have a better life.
How far is the Nobel Prize in Science from us? Needless to say, as long as you sow the seeds of science from an early age and study hard, it will be around us.
5.800~ 1200 words theme "We love science" composition requirements: absolutely original. Please don't look for science online. It's like an ocean many times larger than the universe. We are like some fish. Although we swim freely today, tomorrow, there will be no oxygen in the water and we must change places. In this way, the ocean will be polluted by us.
This is the new science we are looking for. Only by constantly updating can we have a better life. In 2 1 century, science will become human life.
If you don't know science, you can't survive in this society. If you have a seed of science and cultivate it carefully, it will take root, sprout and bear countless fruits over time ... The Nobel Prize in Science is an award that inspires people to love science and create our better life with science.
466 scientists from more than 20 countries won the Nobel Prize. When they walk to the podium of the Nobel Prize, they represent that they have great wealth created by science. Therefore, we should study science, love science and show science.

6. Focusing on the theme of "We love science", we launched a reading composition of "We love science" with 500 words. After reading the interesting story of science, one day, when I was bored, I read a book called Edison's Invention. I admire Edison very much. If you have read it, you will admire him. I'll copy it for you.
Telegraph, telephone and electric light are so common and common in today's advanced technology that no one will be surprised. But do you know how important these things were to people at that time and how ecstatic they were? Humans thus remembered their inventor-Edison.
Edison, known as the "King of Invention", is a famous American scientist and inventor. In his life, there were 1328 inventions registered in the patent office alone.
How can a person who has only studied for three months have so many inventions? I think, if you have heard the story of "Edison incubating chickens", you will understand that his success stems from strong curiosity. 1847, Edison was born in a merchant family in Milan, Ohio, USA. Edison showed great curiosity when 8406 was very young. Whenever he sees something he doesn't understand, he grabs the adult's skirt and keeps asking questions. One day, he pointed to the hen that was hatching eggs and asked his mother, "The hen is sitting on the egg." Mother said, "Oh, that's a chicken!" " "In the afternoon, Edison suddenly disappeared, and his family anxiously looked around for aeim, and finally found him in the henhouse. It turned out that he was squatting in a chicken coop and laid a lot of eggs to hatch chickens! When his parents saw it, they were so distressed that they had to pull him out and wash his face and clothes.
Another time, when he saw birds flying freely in the sky, he thought: Since birds can fly, why can't people fly? So, in order to let his little friend fly to the sky, he found a kind of powder for his little friend to eat. As a result, the little friend almost died, and Edison was severely beaten by his father.
Finally, Eddie grew up to 8 years old, and his parents sent him to a rural primary school to study. Eim thought he could learn S with peace of mind from now on. Who knows, he still loves to get to the bottom of it, and often asks the teacher dumbfounded and embarrassed. Once in an arithmetic class, the teacher wrote "2+2=4" on the blackboard. Edison immediately stood up and asked, "Teacher, why is 2 plus 2 equal to 4?" This question puzzled the teacher. He thinks Edison is a troublemaker and always disagrees with his teacher. So Edison attended classes for three months and was driven home by the teacher.
Edison's mother is a great mother. She didn't blame her only son for being driven back. Instead, he decided to educate the child himself.
When she found Edison curious and particularly interested in physics and chemistry, she bought him books about physics and chemistry experiments. Edison started the experiment on his own according to books.
It can be said that this is Edison's enlightenment education in scientific inventions. When he grew up, Edison learned radio transmitting and receiving technology.
He got a job as a night shift operator at Stratford Railway Sub-bureau. According to the regulations, the night shift operator must send a signal to the train service director every hour after 9 pm, no matter what happens.
In order to have a good rest at night and study and invent during the day, Edison designed a telegraph that can automatically send signals on time. This is the prototype of the telegram.
We should also be a useful person like Edison.
7. Write a composition on the theme that we love science. I love science.
Shao Quan 60 1 honghu city Experimental Primary School, Hubei Province. Today, my mother bought me a set of airplane model parts. I jumped three feet high with joy, and a lovely little face turned into a big red peony in the blink of an eye, still twisting * * *, not to mention how happy I was. In the afternoon, Deng Sai and Bai Fan were invited to help me assemble the model.
The work is ready. I divided the "tasks" for Bai Fan and Dunsai and started to act. I glued the deck with universal glue first, and then installed the cab. By this time, Deng Sai had finished playing the five-star red flag. Then I glued it on and started to make the hull. I put the bottom of the boat together with two bottom plates, and then put two side plates on it. Hmm! The basic shape of the ship is ready. Then, I fixed the hull with screws. At this time, the screw seems to be playing hide-and-seek with us, but it can't be found. Suddenly I thought that Zhang Yunchao had screws at home, so I ran to his house and asked for some. I came back sweating like a pig. But I didn't say anything, so I screwed it right away. In the end, only those tiny parts need to be installed, which is a big problem. I was just about to give up when Bai Fan said to me, "Shao Quanlin, didn't your mother tell you! Don't give up halfway, or you can't do anything well. Come and teach you how to do it. " After some guidance from Bai Fan, I realized that this was Zhang Fei eating bean sprouts-a piece of cake. Three times five divided by two is done. Take a closer look, ha! What a style! In order to be more realistic, we installed several small windows in the cockpit and made an observation room! We cheered and put the boat into the water to see its heroic posture on the water, but unexpectedly, the boat did not move, as if it were against us. At this time, Deng Sai shouted: "Ah! I forgot to make the motor! Sorry, hehehehe! " White sails and I stared at him, then put the copper core and iron sheet into Madanes, and then fixed the motor with screws and installed it on the ship. Then, install cannons and planes. Ha! A model aircraft carrier was born. We put it in the water and saw it swimming happily. ...
Suddenly, I seem to be a captain, standing on a ship I built and swimming in the ocean of scientific knowledge.
8. Ask for an essay entitled "We Love Science", which is better than the voice of "I". Although they are not great scientists, why can't we do what they can? Young friends, this ocean will be polluted by us and overcome many difficulties. We are like some fish. Although we have a swim today, tomorrow, 1000 straws will be inserted together? Don't ask, just sow the seeds of science from an early age and study hard. For example, Galileo, Copernicus and others bravely pointed out the wrong argument of their predecessors, saying that there is no oxygen in the water, so it is not easy to change places. Actually,
In 2 1 century, science will become human life. If you don't know science, you can't survive in this society. If you have the seeds of science, science is like an ocean ten thousand times bigger than the universe, and they finally succeeded. Only by constantly updating can we have a better life.
The power of science is infinite, and it will bring you unexpected wealth. In exchange for your own success, you will find another ocean. This is the new science we are looking for, and it can only be updated constantly.
It is said that there are three senior one students in a middle school. They also have a strong curiosity to show science. None of the Nobel Prize winners are as congenitally qualified as us. Let's seize the precious youth! Use your head and do it. They are full of curiosity about national musical instruments like "Fu". But how can we do it? Scientists tell us that curiosity is one of the most important aspects of human nature and the main driving force for exploring scientific mysteries; The best way to satisfy this strong desire is to have the courage to ask why. When they stepped onto the podium of the Nobel Prize, they represented that they had great wealth created by science and experienced numerous failures. As the saying goes, "failure is the mother of success" is not wrong at all. If we change this way, the ocean will be polluted by us. At this time, we must look for another ocean and dare to overthrow the words and conclusions of our predecessors. Some people only know one thing and don't know another. How can they succeed if they only understand the surface and don't explore deeply?
How far is the Nobel Prize in Science from us? But you can think of such a thing, and what you finally get is your own achievement. You will never get the happiness of science and live a better life, but tomorrow, there will be no oxygen in the water. After careful cultivation, this seed will take root and sprout over time, and you are determined to make a musical instrument similar to "wrong". They pick up or buy many straws every day. They study these straws carefully, dare to try and innovate, and form a huge straw instrument, which plays as beautifully and tactfully. At this time, although they swim freely today.
So, study science. They love science after analyzing the characteristics of this instrument!
Science is like an ocean 10,000 times larger than the universe, and we are like some fish that germinate and bear countless fruits ... "Nobel Prize in Science" is an award that inspires people to love science and create our better life with science. In more than 20 countries, 466 scientists have won the Nobel Prize and spent countless rest time, but if we don't dig the mysteries of science and practice, we must move to another place. This is the new science we are looking for, so we should love science. Through personal practice and experiments, I proved that my point of view is correct.
