In our daily study and work life, we will always come into contact with papers. With the help of papers, we can discuss problems and conduct academic research. Still at a loss for the paper? The following are my scientific papers for your reference, hoping to help friends in need.
In today's world, scientific and technological progress is changing with each passing day, and the competition of comprehensive national strength is becoming increasingly fierce. In this case, innovation ability and innovation achievements become important factors to determine whether a country and nation can win the competition. Encouraging and promoting innovation has become an urgent need to achieve development and progress.
However, everything has the possibility of success or failure, especially innovation as an exploratory practice. For innovators, success is a test and failure is also a test. Indulge in the glory of success, often may stop the pace of progress; Unable to get out of the shadow of failure, it is easy to miss the opportunity of success. Edison, the inventor at that time, tried many times to find a filament that was not easy to burn out, but failed. When many people sighed for his failure, Edison said: I didn't fail, I just found something that didn't meet the requirements. After unremitting efforts, Edison finally invented the electric light and brought light to mankind with science and technology. This story tells us that never giving up is an important condition to realize innovation.
Innovation does not give up, not to say that all innovation activities can be successful, can be a total victory. Innovation is difficult, it can't be done overnight, and it won't be smooth sailing. Innovation is not giving up, but more refers to a spirit, a quality and a pursuit.
Innovation and never giving up are a kind of spirit. This spirit of not being afraid of failure and daring to win. Failure and success, gains and losses are always relative and dialectical. With great efforts, there will be great gains; Great achievements can only be achieved if there is a great realm. Successful innovators understand the dialectics of success and failure is the mother of success. In the process of innovation, it is common for one thing to fail again and again. In the face of failure, we can neither shrink back nor lose heart. Because of a mistake, it can be a good thing as long as it is slightly adjusted; Repeated setbacks, as long as they persist, can always lead to victory. The real failure is often to be devastated after being frustrated, and all success comes from rising from failure and advancing in development.
Innovation and never giving up are a quality. This quality is to face up to difficulties, never back down. The road to innovation is full of dangers, but the infinite scenery is on the peak of danger. As Wang Anshi said, the extraordinary world outlook is often to stay away from danger, and what people lack is difficulty, so where there is a will, there is a way. In the face of difficulties and obstacles, "retreat" has no way out, and "timidity" is difficult to win. Innovators should have the heroic spirit of "water under the bridge, destiny takes a hand", and the more frustrated they are, the more courageous they are. There is no royal road to innovation, and only those who are not afraid to climb along steep mountain roads can hope to reach the peak of glory.
Innovation and never giving up is a pursuit. This pursuit is to work hard and forge ahead. Innovation is the soul of a nation's progress and an inexhaustible motive force for a country's prosperity. To promote the cause of Socialism with Chinese characteristics and realize the great rejuvenation of the Chinese nation requires and calls for innovation. Innovation is the pursuit of entrepreneurs, never giving up, and self-confidence and self-improvement is the choice of innovators. Self-confidence can summon up the courage to start again; Self-improvement can stimulate the potential of seeking up and down. Confidence is not conceit. Confident people have self-knowledge, know how to foster strengths and avoid weaknesses, and will not act rashly. Self-improvement is not being brave. Self-improvement, clear-headed, good at sizing up the situation, and don't stop until you reach your goal.
Innovation is not easy, and victory or defeat is common. Therefore, we should be more understanding and tolerant of those who are committed to innovation and strive to create a social environment and atmosphere conducive to innovation. For successful people, we should present beautiful flowers and give sincere praise; For losers, we should also show full understanding and provide necessary help. Only in this way can the vitality of innovation be generated and the achievements of innovation emerge continuously.
The world is developing rapidly, human life is progressing, and science and technology are changing our lives. Everyone has different views on science and technology, which may be that the advantages outweigh the disadvantages, or that the disadvantages outweigh the advantages. In my opinion, there is no doubt that the advantages of technological development outweigh the disadvantages.
Throughout thousands of years of human history, since the Stone Age, human beings have been inventing various ironware, and by the beginning of the19th century in age of steam, human science and technology had begun to take off gradually. In today's information age, there are many high-rise buildings, and people enjoy the convenience brought by science and technology. Life is more convenient than before.
The network we often use has many conveniences. Nowadays, the speed of information is constantly expanding. If you want to keep pace with the times in the information world, you must make good use of the internet. In the past, if we wanted to know something specific, we had to go to the library to look it up book by book. But now with computers, we can save a lot of time, and what we learn on computers is also comprehensive. Furthermore, the network has given us a platform for communication, which is the school newsletter where we are now. There are many excellent friends in this place. We have not only exercised our writing ability here, but also made more friends and improved our social skills to a certain extent. Isn't it enough that the internet has brought convenience to everyone?
In ancient times when there was no rapid development of science and technology, people were superstitious about ghosts and gods, believing that human life was decided by heaven and fate was controlled by heaven. But in modern times, people have proved that superstition is not desirable, and they should decide their future through their own efforts. In ancient times, if a person was seriously ill, doctors could only watch the patient die. Now, the development of science and technology also leads medicine all the way forward. Many incurable diseases that ancient people thought should be solved have obviously improved the medical level ... Of course, this is only the tip of the iceberg, and the development of science and technology has brought endless convenience to mankind. If the development of science and technology is wrong, then why should those great scientists dedicate their precious lives to science? Can't celebrities like Newton, Galileo, Edison and Madame Curie judge whether their chosen careers are correct or not? Don't their contributions to mankind mean anything?
We live in a happy era, and we are also lucky, because we live in an era of rapid progress in science and technology, and our beautiful life is bought by many scientists with their wisdom and persistence. The development of science and technology has promoted the rapid progress of our country, making our country strong and capable of standing in the world. So I always believe that the advantages of technological development outweigh the disadvantages!
Everyone wants to build a lot of high-tech things, and I also want to build one thing, that is, "advanced roller skates."
Let me describe the "advanced roller skates" I want to make now. The top appearance of this pair of advanced skates is exactly the same as that of ordinary skates, but the bottom is quite different. There are ultra-high-speed motors, several wires, eight luminous wheels, two wheels in front, two wheels in back and four wheels in the middle. There are two light bulbs in front of the skates, a governor on the left side of the left shoe and a governor on the right side of the right shoe, and high temperature protection is installed in the shoes. The skates also wear a high-grade armor hat and a controller on their arms, which can control: the brightness of the light bulb, the speed, 180 degree turn and the storage location of things. I also introduced its function. This pair of advanced roller skates, its speed can reach 1000 km per minute, 60000 km per hour; The highest temperature of the motor can reach 100 degrees, and the motor is also very, very temperature-resistant; The wattage of the light bulb can reach 1000 degrees, the nearest 50 meters and the farthest 1000 meters; Wheels can bear 300 pounds of things; The anti-high temperature system in the shoes can prevent it to 50000 degrees; The hat has a helmet outside and a soft and comfortable sponge inside. The temperature in the hat can be adjusted by the controller. The hat is also equipped with a microphone and headphones. The controller can also adjust the headwind to the downwind. There is a propeller on the hat. In the sky, the hat can also block large airflow and clouds, and there is unlimited oxygen inside the hat. If you can't see the route ahead in the sky, just press the button and a screen will appear inside the hat. Look at the route ahead from the screen. If you look at the electronic world map, you can see your country and where you are on the screen. There is also a red line on it. The function of this line is how to return to your country. In case of emergency, the skates will automatically turn; If you buy too many things that are inconvenient to carry, the skates also have a special storage place for things, so it will be much easier to put things in. "Where there is a will, there is a way." As long as you have perseverance in what you are doing, you will be able to make this "advanced roller skates".
Last year, I participated in the third science and technology competition in Luoyang, and I won the second prize. I am very depressed. Miss Bai comforted me by saying: If we give up too easily, we may not realize that we are very close to being right. Learn from experience and lessons, and we will participate again next year. No, as soon as I received the notice this year, my teacher told me to continue to participate in the fourth Luoyang Science and Technology Competition. I jumped three feet with joy, and it's time for revenge.
As soon as I got home, I found 600ml mineral water bottles, thick and thin straws and plasticine, and made them according to the method my teacher taught me last year. After I finished it, I went to the stadium to release it. Sadly, it turned out to be 8 or 9 meters away, the same as last year. How can I win the first prize?
When I arrived at school the next day, I asked Miss Bai for help. Teacher Bai inspired me: think about how the students who won the first prize last year did it. I recalled that the students who won the first prize last year seemed to use a long tube. The most special thing is that they step on the bottle with their feet and I pinch it with my hands. The teacher asked: is it hard to step on the foot or pinch the hand? I patted my forehead and smiled at the teacher.
When I got home, I asked my father to buy me a long and thick pipe. However, after installation, it was found that although the launching distance was far, the thick pipe was too long and difficult to grasp. I almost stepped on it several times and twisted my foot. It's really easier to watch than to do! Dad told me not to be discouraged: hard management is no good. Let's try the hose.
On Sunday, my father and I visited all the shops in Xin 'an County, and finally bought a satisfactory soft long pipe. This time, I carefully checked the tightness of the bottle cap, the length and weight of the arrow. Everything was ready, and Dad gave the order: "Launch!" Dad measured it. Oh, my God, it's more than 20 meters. It worked! Dad told me that if we adjust the angle of launch, we will shoot farther. I decided to practice after school every afternoon, and I must shoot the farthest distance.
"Nothing is difficult in the world, as long as you are willing to climb." Many things in the world can be successful as long as you work hard and be good at thinking. This incident aroused my interest in science. I will definitely study hard and expand my thinking space. When I grow up, I will study science seriously and climb the peak of science forever!
The scarf heart sends a message to the party, the robot of the future, and the graduation of the teacher. The sun of the ancients slowly reveals a swollen face through the clouds, like a shy little girl looking at the earth. Small stars in scientific papers, like pearls, are embedded in the sky and shine. The frog's green body is covered with dark green spots, and its white belly seems to be expanding and bulging. The spring rain kept falling, and the thin rain silk woven into a huge net, hanging from the clouds to the ground. The dark mountain in the distance, the pink peach blossom nearby, the green poplar and the soft willow branches are all shrouded in this boundless net. This net is a gauze skillfully woven by Miss Chun, covering the sky and the sun.
When my cousin first came, she wore a plaid shirt, a few patches and a pair of white sandals stained with mud. She dare not speak loudly when she walks. We all call her rustic. But now, we dare not say cousin. Look at her wearing a beautiful coat, a pair of tight jeans, a pair of shiny high heels, a shiny gold necklace around her neck and long black hair over her shoulders. She looks dashing. Talking and laughing at home is like living in honey. When I think of the speech, the little artists around me, the moon, the blue sky and the sun are hanging like a fireball, and the clouds seem to have been melted by the sun and disappeared without a trace. When I got home, I looked at my father in dismay. He is tall, broad-shouldered, wearing a faded military uniform and a pair of bright big eyes embedded in his bronze face. There are already several wrinkles on the forehead. At this time, my father may find me looking at him, so he kindly asked, "Hey, what are you thinking?" I said unhappily, "Dad, how did you go back to your hometown to farm when you were a PLA man?" ? People ask me what you do, but I dare not say. "
Dad listened to Zheng, his eyes lit up and his eyebrows suddenly picked up. He said, "Lu didn't have this idea, and even Dad looked down upon it. Without the hard work of our farmers, where did you get the rice bowls, vegetables and fruits you ate? "
In the deep blue sky, there is a bright and dazzling diamond star-the morning star.
Science and Technology Paper 6 Science and technology progress with the leap of mankind, and the problems arising in the progress may be obstacles that have to be faced in the progress. How to think about countermeasures is bound to be a problem that the new generation should reflect on.
The virtual reality "Bao Mengke", which swept the world not long ago, is a good case. At first glance, it seems to have been a long time ago. Looking back carefully, I feel that it has been more than a year, but it seems to have been forgotten by the public. The progress of science and technology is several times that of our imagination. A dazzling is a new development, and the problems derived from it can be as beneficial as a double-edged sword. There are hundreds of miracles created by science and technology, among which mobile virtual games can not be ignored. When Baokemeng was first introduced, it became a hot topic in the news media at that time because it combined the most advanced virtual reality technology, and most of these topics were negative cases.
In fact, there is not much difference between the word mobile game and the online game type of desktop computer. In addition to clicking by hand, the reason why it is getting bigger and bigger is probably beyond the space limit. In the past, games played by humans were generally confined to one corner, but now players are willing to go outdoors, which is undoubtedly positive. However, just because of going outdoors, its spread has expanded, and the frequency of making others unhappy will also increase. Games are easy to indulge. At present, it seems that there are only games and players in the world, and others can't see them, so there are problems of breaking into houses or causing traffic safety doubts. This is one of the most criticized concerns.
Even so, a sinful person may have something to learn, not to mention that there is no absolute theory in the world, and the disadvantages will be beneficial. According to the report of American researchers, most of these people who love this kind of real-life game are more willing to share their joy with others and help others. It is not difficult for them to lend a helping hand, because the concept of mutual assistance is gradually developed in the game, which will naturally affect the behavior pattern in real life. Selfishness is a common problem of people, but it can bring back kindness in the game. This is undoubtedly surprising good news, but it is often ignored. Stereotyped that all games are negative effects and exclude games.
It's not all bad to enjoy science and technology games once in a while. The quality brought by progress is worth tasting.
Speaking of scientific essays, I recall many small experiments I have done before, and many strange imaginations suddenly appear in my mind. For example, the liquid experiment-the experiment of aloe brewing drugs; Experiment of thermal expansion and cold contraction. In the future world, can we grow a pair of flying wings? Can fish swim in the sky? Can we invent a machine that won't make our hands and feet calluses? ..... Wait a minute. In a word, those fantastic ideas and products I have made reappear in my mind, especially the water experiment, which makes me remember vividly.
When I got home, I first picked up a transparent glass and then poured some boiling water into it. I turned on the tap gently and let the water drop by drop. I thought to myself: haha! The first step is so smooth that the next steps will be smooth! Then I opened the green oil bottle and let the oil pour into the cup little by little. Then I stirred them up with chopsticks, and the water and oil gradually merged together, but after a while they separated and became two layers: the first layer was green oil, and the second layer was boiled water; I thought about it: hey! How about I get some soy sauce and see what happens? I bought some soy sauce and put it in a cup, and stirred it. The soy sauce and boiled water melted together, but the green oil was still on the first floor. I thought, honey? What if I get some honey? Then, I took out some honey and mixed it with these liquids. Although they began to mix together, they became three layers after a while: the first layer was green oil, the second layer was soy sauce and soy sauce, and the third layer was honey.
I can't help thinking: Why are different liquids mixed together? I want to confuse people. In order to understand this truth, I took it to my father and asked curiously, "Dad, look, no matter how I stir these liquids, I always keep three layers?" Dad looked at these liquids carefully, and then mysteriously said to me, "Dear daughter, do you think there is any difference in the weight of these liquids?"
I held this cup of liquid in front of me, looked at it carefully and thought about it: weight? What is the relationship between liquid and weight? I ran to my father with questions and asked, "Are these liquids light or heavy?" Dad replied affirmatively, "Of course!" Dad's affirmative answer suddenly solved the mystery in my heart: Oh! It turns out that the lightest liquid is always at the top, the heavier liquid is at the middle and the heaviest liquid is at the bottom.
Ah! This magical cup of water makes us understand that oil and water are immiscible, and at the same time, it also makes us understand that experiments will make us grow more knowledge and talents.
