There are many great inventions worth mentioning, and there are some comments in the media. It is difficult to choose one of the greatest inventions, so we usually choose a few.
I think the next three.
The wheel has no technical content, which makes people feel very everyday, but for civilization, the wheel is a leap.
In 3500 BC, wheels were used to make pottery, and 300 years later, chariots appeared. Since then, human transportation, commerce and war have been completely changed.
Understanding the importance of wheels can be proved by the history of the New World. The Mayan calendar was round, and so were Native American toys, but they didn't invent the wheel. One of the reasons is that the wild animals in the United States have been extinct by human beings, and there is no animal power to raise. The only alpaca can't pull the cart, so it doesn't need wheels Europeans conquered the new continent not only by guns and bacteria, but also by wheels. One of the reasons for the destruction of American civilization is that there are no wheels.
The steam engine was selected as one of the greatest inventions by some media, but without wheels, there would be no steam engine.
Language is not a great invention, just like fire is discovery. A few animals have something similar to language, but words are unique to human beings, especially popular words. As the saying goes, "Zhong Ni was not born in heaven, but the night is long", and people like Confucius do the writing work. Mayan civilization also had characters, but their hieroglyphics were limited to religious tools used by priests, rather than communication and knowledge accumulation, so Maya disappeared after the collapse of Mayan civilization.
Words allow human knowledge to accumulate and sublimate on the basis of accumulation, so that civilization will not spin around like a circle. Both papermaking and printing, which are rated as great inventions, are based on words. Why do you need paper without words? Why print?
Inca civilization in America has no writing, so it is recorded by tying rope. As a result, smallpox was prevalent in Cuzco, the capital, and the emperor led the army outside. Because there are no words, all kinds of situations are dictated by messengers. As a result, a messenger infected smallpox to the emperor. Before he died, the emperor was selfish and left the elite field army to his beloved son, causing his brothers to turn against each other. When the civil war broke out, the Spaniards got a bargain.
As early as in ancient Egypt, lenses were invented. The purpose of this thing is to make us see more clearly.
Thousands of years have passed, and microscopes have been invented on the basis of lenses, so that people can see microorganisms, and then understand how infectious diseases occur, and then study ways to control infectious diseases. Vaccines and antibiotics have been rated as great inventions by some media, but they seem to prevent and control infectious diseases. If there is no microscope, how can you get infectious diseases?
Telescope is invented on the basis of lens, and astronomical telescope is the first step for human beings to go into space.
Photos, movies and TV in daily life all come from the lens.
This topic needs a complete set of statistical evaluation index system and big data, which is difficult. Consider the length and simplify the answer.
Because the emphasis on invention has nothing to do with physical discovery. Consider an overview, first list the top ten inventions, and then list the top ten discoveries.
Then for the three indicators of A universality (universal applicability), B dominance (dominant control) and C aggression (sudden jump), the full score is 10, and the one with the highest comprehensive score is the first.
Universal score-10, on the grounds that the invented product will involve the definition of structure and function.
Master score-5 points, the reason is that the elements of invention and creation involve technical details and careful layout.
The enterprising score is -3, because the breakthrough of invention technology depends on the advanced nature of material science.
Comprehensive score-18.
The universal score is -8, because all inventions in engineering and technology involve pi, but not in social science.
Master's score is -5, because pi is only a common parameter in design, but it does not involve the operation of rational numbers.
The offensive score is -4, because pi runs through the whole history of invention and has no obvious contribution to epoch-making inventions.
Comprehensive score-17.
Explanation: Geometric zeros, straight lines, planes, conic curves and spheres are abstract inventions, and nature does not exist-the whole mathematical building is an invention of human beings.
The general score is -5, because antibiotics have made great contributions to medicine, but they are not applicable everywhere.
Proficiency score -5 points, because: only proficient in anti-inflammatory and immune aspects.
Aggressive score-10, because, for example, penicillin has made outstanding achievements in fighting respiratory diseases.
Comprehensive score -20 points.
Universal score -9 points, the reason is: indirectly, human beings can hardly live without power. But there are many exceptions.
The master's score is -9. The reason is that if there is power failure, life and work will be seriously affected, and civilization will go backwards for 300 years.
The enterprising score is -9, because the power industry has greatly promoted the process of civilization since the British industrial revolution.
Comprehensive score-27 points.
The universality score is-10. The reason is that computers and derivative mobile phones are almost everywhere, and we have not considered backwardness here.
Master's score -9, the reason is that computers and mobile phones are almost indispensable to everyone and thousands of households in all walks of life.
Aggressive score-10, the reason is that computers, as the greatest invention in the 20th century, greatly accelerated the process of civilization.
Comprehensive score-29 points.
Universal score-10, the reason is: there is no doubt that the invention of money and its concept involves thousands of households in all walks of life.
The master's score is -6. The reason is that money may not be everything, and money is absolutely impossible without it, but money is not the decisive factor.
Aggressive score -8, the reason is that money, as a currency, has greatly promoted the commodity economy, but the epoch-making boundaries are blurred.
Comprehensive score-24 points.
Universal score-8 points, the reason is: history has written records, civilization can hardly be separated from words, but there are also spoken languages.
The master's score is -8, because although written language communication is almost indispensable, oral communication can also be effective.
Aggressive score -9, the reason is that only written records can be considered as the inheritance of human civilization, and it does not rule out word of mouth.
Comprehensive score -25 points.
Universal score-10, the reason is that the contract involves social division of labor and cooperation, involving all laws and regulations.
Master score-10, the reason is: all human behaviors are controlled by contracts, and there are agreements with people in heaven and earth.
The offensive score is -3, because the contract runs through the whole history of civilization, but it has no significant epoch-making significance.
Comprehensive score -23 points.
Universal score -9 points, the reason is: after the bronze civilization, it is mainly the steel civilization, which is the overall significance of history.
The master's score is -8, because most life, production and public facilities are almost inseparable from steel.
The enterprising score is -5. The reason is that iron, as a production tool, wins by quantity, and in terms of materials, it is slightly inferior to semiconductors.
Comprehensive score-22 points.
Universal score -9 points, the reason is: the wheel is an extension of the lever principle, and almost all mechanical transmission can not be separated from the wheel.
Master score -5 points, the reasons are: the wheel is not unique, the power transmission mode, and electricity, light and heat.
Aggressive score -5, the reason is: before the lever principle, there were wheels a long time ago, and its epoch-making nature was not outstanding.
Comprehensive score-19.

The author thinks that Newton's three laws are the greatest scientific discoveries. Because Niu Yi can derive principle of least action, Niu Er can derive the law of conservation of energy and Niu San can derive the law of conservation of momentum.
Newton's three laws, in particular, are applicable to both macroscopic celestial bodies and microscopic particles, and can be regarded as the first principle of nature.
All right, Ben, stop here. Please pay attention to the new vision of physics and discuss the difficult problems of physical logic and Chinese-English bilingualism.
It must be electricity. Accurately speaking, electricity was not invented but discovered, but invented a series of applications of incoming calls, such as generators, lights, telephones, mobile phones, televisions and so on.
Electricity was discovered in ancient times, but it was not paid attention to and studied. It was not until 1732 that Franklin, an American, used kites to draw electricity. 1799, an Italian Voltaire made a set of batteries. The most important person is the Englishman Faraday, who made the world's first electric motor. Maxwell, a scot, put forward the electromagnetic theory. Croatian-born nikola tesla invented alternating current in the United States, thus opening the curtain of the second industrial revolution.
Great changes have taken place in human life since the advent of electricity. If there is an era before electricity, there is another era after electricity. Human civilization can be divided into two eras according to electricity, one is the era of cold weapons and the other is the era of electricity.
Electricity has given human beings wings to fly. Cars, planes, ships, submarines and spaceships enable human beings to explore more and more fields. Now China's Chang 'e IV has landed on the back of the moon. All this is done on the basis of electricity.
The significance of electricity cannot be overemphasized.
The greatest inventions of mankind are China's papermaking and printing. The invention of gunpowder compass is also great, but in terms of its extensive and profound influence, the first two inventions should be popularized.
Paper making. Invented by China in the Western Han Dynasty and improved by Cai Lun in the Eastern Han Dynasty, it is called Cai Hou Paper. The invention of papermaking is a great revolution of human writing materials.
Printing. Engraving printing appeared in Sui and Tang Dynasties in China. The Diamond Sutra, printed in 868, is the earliest printed edition in the world. 1 1 At the beginning of the century, Watson invented movable type printing in the Northern Song Dynasty. Four centuries before Europe. The invention of printing is a great contribution to the spread and preservation of human culture.
In 2007, China's four great inventions were rated as world-changing inventions by the British newspaper The Independent.
Marx once commented on China's ancient invention, saying that it was a great invention and predicted the arrival of the bourgeoisie. Explosives shattered the medieval earth-riding class, the compass opened the world market, established colonies, and printing became a tool of Protestantism.
Bacon, the founder of modern experimental science, wrote in the book New Tools that these inventions changed the whole face. With such great changes, no empire, no school and no celebrity can play a more important role and influence in the cause of mankind than these inventions.
Maybe we won't believe it, maybe you really ignored that the greatest invention of mankind is the hierarchy of 369! Think about it carefully, the equality of human beings runs through every corner of human society, and no one is left behind. Whether it is a higher-level community or the poor, the hierarchy permeates it, restricting and controlling your words, deeds and thinking at all times. Because of fear and ignorance, the general public listened to the absurd and contradictory division of labor and dedication of the so-called ruling class and tried to appease people's hearts and seek social stability, but they didn't know that those who were eager to move emerged one after another, so ancient peasant uprisings emerged one after another without hesitation! The greatest invention is not the progress of technological extraction, but there is always a limit. What makes people wonder is that the upper class is extravagant and indulgent. The greatest invention in the world is that the government loves the people as a child, treats the people well, thinks for the people, serves the people, is sincere, and works tirelessly for the country and the people regardless of returns!
I think this greatest invention can be viewed from different angles, such as field.
