[Urgent] The role of invention and creation in the progress of human society. thank you
In today's society, people can't live without the Internet. Communication through the Internet is one of the main ways of communication in today's society. Opening a webpage is tantamount to shaking hands with the world. Watching news, doing business, making friends, inquiring information and seeking medical advice, we don't need to travel by boat, and it doesn't take time and trouble to realize our wishes. Network plays an important role in contemporary society. It transcends space, seniority, age, occupation, status, appearance and so on. , and provides a platform for equal exchanges, extensive contacts and free activities. In the network, we can find study materials and instructors, and we can also find like-minded friends on the network. In the network, we can expand our communication fields and objects, change the previous communication methods and enrich our life experience. Network is not only a kind of communication, but also a way of communication. Network plays an important role in the development of human society. Network is the crystallization of human wisdom, and it is also the center with the largest capacity, the most complete content and the fastest communication speed that human beings have so far. With the development of mankind, the Internet has become more and more high-tech. However, there are also some bad factors in the network. For example, some games in the network are addicted to it, and some people even give up their studies for it. It is sad that they are addicted to online games and make them physically and mentally disabled. The internet is not everything to us. We should not be the captives of the network, but the masters of it. We should take surfing the Internet as a supplement to our life, so that we can enjoy many benefits of online communication, such as broadening our horizons, relaxing our mood, learning new knowledge and making new friends. There are many similarities between online communication and real communication. Many warm and touching stories are spread through the internet, which makes people all over the world know the power of online communication. In today's network society, the network provides convenient conditions for us to understand current events, learn knowledge, get along with people and entertain. We can use the Internet to meet some of our daily needs. In network communication, we should pay attention to browsing and looking for information related to learning, don't stay in front of irrelevant information, let alone waste energy on boring information, and learn to resist bad temptations on the network. We should be good at using network technology to solve problems in work, study and life, help others solve some difficulties, do something beneficial to others and society, and show our life value in serving others and society. We should be a person with ideals, goals and pursuits. We should go beyond life and arrange things in an orderly way, instead of wasting time on things that are not beneficial to us. We communicate on the internet; The object of communication is virtual, indirect and hidden. It enables us to freely choose communication partners online, speak freely, and fully display our inner cultivation in online communication, without having to shrink back because of poor age and appearance and poor oral expression ability. At the same time, people's dark psychology can be freely vented with the help of computer screens, which pollutes the communication environment. We may be the victims of this polluted environment, or we may inadvertently participate in it to add fuel to the flames and destroy the network environment. Some psychologists put forward 10' s "Internet addiction" standard: (1) After logging off the line, they are always obsessed with network affairs; (2) I always feel that time is not enough and I am not satisfied; (3) Unable to control Internet access; (4) Once you reduce your online time, you will feel anxious; (5) You can forget all kinds of unpleasantness as soon as you get online; (6) surfing the internet is more important than going to school; (7) I would rather give up important interpersonal communication and work for surfing the Internet; (8) Do not hesitate to pay huge Internet access fees; (nine) for relatives and friends to cover up frequent online behavior; (10) I feel alienated and lost after getting off the net. Psychologists believe that as long as there are more than five kinds of 10 in one year, it belongs to "Internet addiction". It is not good to spend too much time online. At present, there are many teenagers who have no owners and the largest number of internet users, which has a certain impact on their study. Many teenagers will be addicted to the internet if they can't control themselves. For them now, the Internet is their main entertainment. Sometimes they will indulge in the internet when they are in class or doing other things, thinking that the internet will become his burden over time. Therefore, we should be alert to the Internet. Playing computer too much will make us addicted. We should correctly understand the network, foster strengths and avoid weaknesses, and give full play to the positive role of network communication in promoting life. We should enjoy the fun of healthy communication. Therefore, the network plays an important role in society, and it also plays an inevitable role.
Mathematician Gauss created inventions and promoted the progress of human society. Gauss didn't say anything about sequences.
Gaussian fitting
Gauss and Gauss are named after Gauss.
Furthermore, Li Man's mathematics was invented by Friedman under the guidance of Gauss, which is of fundamental significance to general relativity.
The invention of the compass has played a very good role in the progress of human society: it enabled navigators to cross the ocean, provided favorable conditions for Columbus da Gama Diaz and Magellan to cross the ocean, promoted the discovery of the new continent, strengthened economic and cultural exchanges around the world, and promoted the development of European capitalism at the same time, and established an imperialist colonial world by plundering gold and labor in Asia, Africa and Latin America.
The bad side: because the invention of the compass provided conditions for the primitive accumulation of capitalism in Europe, they plundered gold, silver and labor from Asia, Africa, Latin America and other places, which led to the long-term backwardness of these areas and the emergence of a single economy, which was controlled by capitalist powers and is still a poor country.
Inventions and creations and the changes they bring to human society bring depression to themselves.
The role of education in promoting social progress without education, there will be no progress, and without education, there will be no continuation of knowledge. There are no innovative ideas. Education is the foundation of the country and the source of social development.
The role of institutional innovation in social progress Innovation is the soul of a nation and an inexhaustible motive force for a country's prosperity. Every field of human society has the possibility of innovation and needs innovation. Therefore, the forms and contents of innovation vary widely, and the types are also diverse. Generally speaking, you can create
It is divided into two basic types: technological innovation and institutional innovation.
Technological innovation is the "hardware" of social development, and institutional innovation is the "software" of social progress, which plays a key role in social progress and development and is the power source of social progress.
First of all, innovation can change people's way of thinking and behavior and stimulate people's creativity.
Create enthusiasm. Society is made up of living people, and what constitutes society is people's social practice.
The richness of social life. And all human practical activities are always in a certain branch of thinking.
What happens, what way of thinking and behavior determines what kind of practical activities.
Secondly, innovation is the decisive factor of scientific and technological progress. The essence of science lies in revealing the unknown.
The law of the world, the essence of technology lies in inventing new means to transform the objective world. Their * * *
The same characteristic is to reach new understanding and create new things through new discoveries, which is creation.
New basic functions. Innovation not only decisively affects the invention and creation of science and technology, but also determines
The qualitative impact of scientific and technological inventions into direct social productive forces in time,
Finally, promote the rapid development of social economy.
Finally, innovation directly promotes social change. In the final sense, social change is
Caused by the development of productive forces, it is finally reflected in a series of institutional changes, that is, constantly
The backward system was replaced by the advanced system. Therefore, the replacement of the old and new systems is actually
The process of institutional innovation. The so-called social reform means everything except the people.
Do not meet the requirements, do not meet the development of productive forces, and do not meet the characteristics of the times.
Political system, economic system and other social systems have been replaced by newer and better systems.
An old system that does not meet the actual needs. Therefore, the process of reform actually also
This is a process of institutional innovation.
-Quoted from Baidu
What human beings invent and create is like a disaster. He attaches great importance to the observation and study of objective things. Inspired by natural phenomena, he devoted himself to creating inventions. He cut his finger on the grass while climbing the mountain. He picked the grass and examined it carefully. He found small teeth on both sides of the grass, so he made a logging saw by imitating the grass. When he saw all kinds of birds flying freely in the sky, he cut them into kites with bamboo and wood and flew in the air with the help of the wind. It took a short time to start flying, but after repeated research and continuous improvement, it has been able to fly in the air for a long time.
The invention of the steam engine
Aircraft-bird
Submarine fish
Cars-Beetle
According to the echolocation of bats
Invented radar
According to the eagle's sharp eyes
Invented the eagle eye for pilots.
The revelation of animals to human beings is that fish swim in the water, and human beings learn to swim and invent submarines.
Inspired by birds in the air, man invented the airplane. ………………
butterfly
Colorful butterflies, such as butterflies with double moon patterns, monarch butterflies with brown veins, especially butterflies with fluorescent wings, suddenly turn into gold, green and blue in the sun. Scientists have brought great benefits to military defense by studying the color of butterflies. This paper points out that the color of butterflies is not easy to be found in flowers, and military facilities are covered with butterfly-like camouflage. So according to the same principle, people later produced camouflage clothes.
dragonfly
Dragonflies can generate local unstable airflow different from the surrounding atmosphere through the vibration of their wings, and use the vortex generated by the airflow to make themselves rise. Dragonflies can soar under a small thrust, not only forward, but also backward and left and right, and its forward flight speed can reach 72 km/h. In addition, the flight behavior of dragonflies is simple, with only two pairs of wings flapping constantly. Scientists have successfully developed a helicopter based on this structural foundation. When an airplane flies at high speed, it often causes violent vibration, and sometimes even breaks its wings, causing the airplane to crash. Dragonflies are safe when flying at high speed, so people follow the example of dragonflies and add weights to the two wings of the plane to solve the thorny problem of vibration caused by high-speed flight.

The invention and development of submarines were inspired by fish diving. 1775, after the North American War of Independence broke out, the British colonial rulers relied on their maritime superiority to assemble a large number of warships and bombed the US navy and army in turn, causing heavy casualties to the US military. At that time, there was a general named David bushnell in the American army. He couldn't stand being bullied by the British and was determined to fight back. He has been thinking hard: how can we sink the enemy ship? From the air, inaccessible; You can't hide from the water. Once, when he walked to the reef by the sea, he suddenly saw a big fish dive under a small fish, jumped up suddenly and bit a small fish. He was greatly inspired by this "naval battle": Can he build a ship like a big fish and dive into the bottom of a British warship unnoticed and sink it? Fish float and sink freely in the water by the swim bladder. Can a boat imitate a swim bladder? Starting from this idea, bushnell and military experts have successfully developed a motorboat that can sneak underwater. The bottom of the boat is a water tank similar to a swim bladder. There are two pumps in the water tank. When the ship sinks into the water, it will fill the cabin with water. When the ship is about to rise, it will press air into the water tank and discharge the water in the ship. Imitating the fin, two propellers are installed, one is forward and backward, and the other is up and down. The motorboat skillfully subdued the British warship on its first voyage and was blown upside down. After gradual improvement, it has become a modern submarine.
The progress of human society is inseparable from the famous saying of whimsy and invention. The highest desire of human beings is to create a new life from time to time. -Li Dazhao's new era
A person with genius-superhuman character-never follows the thoughts and ways of ordinary people. Stendhal
Independence is the basic feature of genius. -Gold
The name of joy is creation. express gratitude for a favour/kindness
All the good things in the world are the fruits of creativity. -The Mill
It is undeniable that the use of creativity and free creative activities are the real functions of human beings; People's creative activities are people's practical functions; Facts have proved that human beings have found real happiness in creation. Arnold
What inventions were made in the 20th century and what changes have they brought to human society? The great and urgent inventions that influenced mankind in the 20th century.
Steam engine: promoted the development of the whole industrial revolution.
Traditional horsepower or water power cannot provide the power needed for industrial revolution, and the development of steam engine energy has brought more effective and powerful power to the world. Although the ancients began to explore this aspect in the 2nd century BC, it was not until Watt's steam engine was put on the market that the commercial value of the steam engine was really opened. Many historians believe that the development of the steam engine is one of the most important inventions of the industrial revolution, because the appearance of the steam engine promoted the development of metallurgy, coal mines and textiles. The appearance of steam engine and the mechanization of textile industry increased the iron consumption of industry. Because Britain is rich in iron ore and coal mines, the increase in demand has improved iron smelting technology and coal mining industry and accelerated the pace of industrialization. 1804 steam engine train and 1807 steam engine boat greatly improved the transportation conditions and assisted the development of the industrial revolution.
Telephone: Opening a New Chapter in the History of Human Communication
"Mr. Watson, please come at once. I need help!" This is the first sentence that alexander bell, the inventor of the telephone, successfully transmitted by telephone on March 1876. Since then, the telephone was born, and the history of human communication has opened a new chapter.
1973 realized the dream of wireless communication in new york, USA. At that time, the first practical mobile phone in the world was large and weighed 1.9 kg, which was a veritable "mobile phone". Today, 26 years later, the world's smallest mobile phone was born. It is only as big as a pager and much lighter than the first generation of mobile phones.
1964 is another important turning point in the history of human communication. This summer, thousands of viewers around the world watched the live broadcast of the Tokyo Olympic Games in Japan via satellite for the first time. This is the first time in human history to watch things happening thousands of miles away through TV screens at the same time. People not only lamented the spectacular opening ceremony and various competitions of the Olympic Games, but also marveled at the progress of science and technology. All this is due to the geosynchronous satellite invented by harold rosen.
1in the summer of 969, the embryonic form of the internet appeared in the United States. It consists of four computer websites, one in the University of California and the other three in Nevada. 1972, the experimenter sent the first email on the experimental network for the first time, which marked the beginning of the combination of internet and communication. In the 1990s, the Internet began to be used for commercial purposes. From 65438 to 0995, the network developed to the first * * *, which was called the International Internet Year. Driven by the wave of e-commerce, the Internet will have a far-reaching impact on human society in the 2 1 century.
Cars: keep pace with the times.
Cars have changed the whole traffic situation of human beings, and they have become the symbol of every industrial power.
Cars have gone through such a history: 177 1 year, France Lianzhu designed a steam engine tricycle; 1860, French Renault made a car engine with gas as fuel; 1885, Ben Ci and Daimler completed the locomotive of high-speed gasoline engine and the tricycle of two-stroke gasoline engine respectively, and successfully commercialized them. 1908, Ford of the United States mass-produced Model T cars with assembly lines, with low price, high safety performance and high speed. Cars began to spread; 19 12 years, Cadillac launched an electronic ignition starter to make women fall in love with cars. 1926, Daimler Ben Ci, the world's first automobile manufacturing company, was established; 1934, the first front-wheel drive car came out; 1940, many automobile manufacturers stopped production because of the war, and European automobile manufacturers began to turn to the production of military vehicles; In 1950s, Volvo's caravans in Germany became the most popular cars as soon as they were launched. 1970-2000, Japanese cars were popular in Asia, and ultra-high-tech small cars from Toyota, Honda, Mitsubishi and Nissan invaded the European and American markets, rewriting the monopoly of European and American brands.
In fact, the invention of the automobile greatly improved the mobility of human beings, and broadened their horizons and pursued freedom in the 20th century. Of course, the development of the automobile industry has also brought about problems such as land resources occupied by the road network, air pollution, high ticket prices, etc. But in any case, the automobile is indeed leading human beings forward and running forward.
Television: the "devil" created by human beings themselves
Modern people can eat and drink for a day, but they can't watch TV for a day.
The idea and theory of TV appeared as early as 1870. 1884, German inventor Paul? Pukov designed a "scanning disk" with holes. When the disk rotates, these holes divide the scene into small points, which are then converted into electrical signals, and the receiver at the other end recombines the signals into the same but rough image as the original image. 1926, the scot John Beaumond made a camera with Pukov's "big disc".
It was Rakimir Zokin, who immigrated from Russia to the United States, and Philo farnsworth, who was born in Utah, who really made TV with stable pictures. 1939 Expo, the world's first truly clear television broadcast, television was really born.
A big step in the history of human space.
American astronaut Armstrong famously said when he landed on the moon, "For an individual, this is just a small step; For mankind, this is "a big step firmly in the hearts of people on earth." "
1969 At 4 o'clock on July 20th, 500 million TV viewers around the world saw a "black" picture, and a voice from outer space came from the depths of the picture: "Houston, this is Jinghai base, and the eagle cabin has landed!" Next, Armstrong and Aldrin, two astronauts on the Apollo 1 1 spacecraft in the United States, asked the Houston Space Center, "We don't want to rest for four hours, we want to land on the moon immediately." Houston replied: "Agree to land on the moon immediately!" Then Armstrong turned his back outward and began to climb down the ninth ladder slowly. 500 million people around the world have seen this scene.
Landing on the moon is indeed a great progress in human space science and technology, because as Colonel Cernan, the last man to land on the moon, said, "Looking at the earth from the moon, I can't see any national boundaries. I think the earth is a whole, and my whole heart will be open. "
Computer: the hope of the future of mankind
1February 4, 946, representatives of the U.S. military, * * departments and famous scientists crowded together in a room at the University of Pennsylvania. When an army general gently pressed the button, the machine that occupied the whole three walls immediately lit up, and people applauded warmly and cheered loudly: "Eniak is alive!" " "Congratulations to Chief Engineer Arcot." ENIAC "is the first computer in the world.
Gene: The Eternal Password to Solve Life
10 years ago, the scientific community predicted that 2 1 century would be the century of genetic engineering. What is the main course of human genetic engineering? 1866, Austrian geneticist Father Mendel discovered the genetic law of living things. 1868, Swiss biologist Friedrich discovered that the nucleus has two parts: acidity and protein. The acidic part was later called DNA;; 1882, when German embryologist Walter Fleming was studying salamander cells, he found that the nucleus contained a large number of divided linear objects, that is, later chromosomes. 1944, American researchers proved that DNA is the genetic material of most organisms, not protein; 1953, American biochemist Watson and British physicist Crick announced the discovery of the double helix of DNA, which laid the foundation of genetic engineering. 1980, the first transgenic mouse was born; 1996, the first cloned sheep was born; 1999, American scientists cracked the sequence map of the 22nd human genome. The future plan is to prescribe drugs for related diseases according to the genetic map.
What role does ideology play in the development of human society? It reflects the real social life from different aspects.
Ideology is an abstract theory, but it is not a purely empty thing.
It is directional and always points to reality.
Whether it is the dominant political thought.
Or non-dominant ideas and theories.
Either maintain the existing political system,
Either criticize the existing political system.
