The price may be a little higher than that of other Shanzhai, but it's not cost-effective. For details, please refer to the interstellar unlimited official Internet bar. I'll know by comparison.
4. Gravity beneficiation is a method of separating ore according to mineral density difference, which plays an important role in modern beneficiation methods. After about 400 years of development, this set of mineral processing equipment once appeared floating phenomenon. However, after a long period of development, gravity separation still exceeded flotation and magnetic separation in terms of ore processing capacity. From the workshop type jigger to the emergence of shaker, gravity separation process has been basically formed. The main types of gravity separation process are classification, jigging, shaker and chute, The above gravity separation process is almost the only mineral processing method at the end of the 19th century, which also established the status of gravity separation in mineral processing methods. In the 1940s, under the guidance of the Americans, gravity separation broke through the original vertical flow and inclined flow separation modes, increased the application of static separation and rotary flow, that is, the advent of spiral washer, laid the basic pattern of modern gravity separation process
gravity beneficiation is mainly aimed at coarse-grained ores, which has a great advantage in the preconcentration application of coarse-grained ores and the separation of fine slime, which is beyond the ability of other beneficiation processes and has been widely used. Gravity dressing equipment is also very simple in terms of manufacturing, and the technology is relatively mature. In the proction of mineral processing, expensive reagents are not consumed, which not only saves the cost, but also reces the environmental pollution caused by the tailings discharged from the gravity mineral processing equipment. With the development of society, people pay more attention to the ecological environment, and the emergence of energy crisis, the graal rection of mineral resources, the superiority of gravity dressing has been affirmed again, and a new development trend has appeared, In recent years, a variety of dynamic heavy medium separators and flow film processing equipment are the signs of this development
as a manufacturer of large-scale mineral processing equipment, Minglei heavy instry group realized that gravity mineral processing equipment was developing towards large-scale, multi-layer and centrifugal force application. In the early theoretical research of gravity mineral processing technology, it tried to express the essence of the process with simple concepts, with different views, most of which focused on the explanation of process phenomena, In the 1950s, with the emergence of a large number of modern ideas and instruments, experts and scholars began to use modern measurement techniques, including rapid photography, radiolocation, optical measurement and other methods to visually describe the movement of particles and media. However, in order to make analytical expression of these observation results, few have done so far, So far, there is no qualitative development of gravity mineral processing theory< Up to now, except for the problem of particle sedimentation, most of the process principles have not been clearly defined. It is difficult to make quantitative calculation. So in recent years, the research based on probability statistics and simulation similarity has been carried out. Through the statistical analysis of process variables or the extension of essential knowledge, an empirical mathematical model or theoretical similarity relation is established, which can be used as the basis for proction calculation, control or equipment enlargement design. Therefore, gravity beneficiation is moving from empirical technology to scientific and mathematical way
China is a country rich in mineral resources. The development of gravity beneficiation technology has also experienced the transformation from ancient times to modern times, and a large number of large and medium-sized gravity concentrators have been established. Great progress has been made in the research of beneficiation methods. Gravity separation method has been popularized and applied to treat iron ore, and heavy medium pre concentration workshops have been established in lead, zinc and antimony non-ferrous metal mines, Of course, gravity separation method is also widely used in building materials, chemical instry, especially coal instry, and has reached the world advanced level. However, there are still problems in the development. There is still a gap between China's concentrators and developed countries in terms of technology management, material and energy consumption, which requires further efforts in order to reach the world's advanced level in an all-round way.

1. [Edison]
one day, his mother was busy in the kitchen. Edison seemed to have made an amazing discovery and asked with wide eyes: & quot; Mom, that hen in our family is really strange. She sits with her eggs under her buttocks. Why& quot; She put down her work and said to Edison seriously: & quot; Mother chicken is hatching baby! When she warms the eggs, chickens will come out. Look at our fluffy chickens. They are all warmed up by their mother& quot; Little Edison thought it was amazing. He thought seriously for a moment, looked up and asked: & quot; Can you put the eggs under your buttocks and warm the chickens& quot;& quot; Yeah, that's it& quot; Mother nodded with a smile. When the meal was ready, my mother suddenly found that little Edison was missing. She couldn't find him anywhere. In a hurry, she called out her son's name. At this time, I heard his promise from the warehouse. Mother felt very strange. She went to see that Edison had made a & quot; Nest & quot;, There were a lot of eggs in it, and he was squatting on top. Mother was even more surprised and asked: & quot; What are you doing& quot; Edison said: & quot; Mom, don't you understand? I'm hatching chickens& quot;

7. Fun under the fence
there are many famous scientists in the world whose families are poor. On the road to success, they all fought against the hardship. The circumstances of Newton's youth are also very sympathetic< Newton was born in 1642 at the home of an ordinary farmer in England. Newton's father died shortly before he was born. His mother remarried when he was two years old. When Newton was 14 years old, his stepfather died and his mother returned to his hometown. Newton was forced to leave school and go home to help his mother farm. His mother wanted to train him to make a living on his own and ask him to deal in agricultural procts< How reluctant a studious child is to leave his beloved school! He cried several times, but his mother didn't change her mind. At last, he had to learn to do business against her will. Every morning, he and an old servant went to a big town more than ten miles away to do business. Newton didn't like business very much. He entrusted all his affairs to his old servant, but he secretly went to a place to study
as time went by, Newton became more and more disgusted with business. All he liked was reading. Later, Newton simply did not go to the town business, only asked the old servant to go alone. Afraid that his family would find out, he went out with the old servant every day, stopped on the way and read under a fence. When the old servant came back in the afternoon, he would go home together
in this way, day after day, the reading life under the fence is endless. One day, he was reading happily under the fence when his uncle saw him passing by. Uncle a look at this scene, very angry, loudly scolded him for not doing his job; Grab Newton's book. My uncle was moved when he saw that what he was reading was a mathematics book with various marks on it. My uncle hugged Newton and said excitedly, "my child, just develop according to your ambition. Your right path should be reading."
after returning home, my uncle tried to persuade Newton's mother to abandon business and go to school. With the help of his uncle, Newton returned to school as he wished.

1. Newton was very attentive when he was engaged in scientific research, often forgetting the little things in life. Once, the old lady who cooked for Newton had something to go out, so she put the egg on the table and said, "sir! I'll go shopping. Please cook an egg yourself. Newton, who was concentrating on the calculation, did not raise his head. When the old nurse came back, he asked Newton if he had boiled the eggs, and Newton said without raising his head: "boiled!" The old lady lifted the lid of the pot and was shocked: there was a pocket watch cooked in the pot, but the eggs were still in place. Newton was so busy calculating that he threw his pocket watch into the pot
When Newton was in the orchard at home, he was walking and thinking, so he accidentally bumped into the apple tree in the orchard. At this time, an apple just hit Newton on the head. Newton suddenly woke up from the problem and picked up the apple. At this time, he fell into another problem: Why did the apple fall to the ground instead of floating into the sky. Finally, Newton put forward the simplest law of the world: universal gravitation When Franklin was 7 years old, alts gave him a lot of money for a holiday. Franklin plans to use this "huge sum" to buy some toys in the store. On the way, he saw a boy blowing his whistle with great air. He was completely fascinated by the whistle at that time, so he exchanged all his money for the boy's whistle When he got home, Franklin was very proud to blow his whistle around the house, but he disturbed the whole family. When his family knew about the deal, they told him that for the whistle, he had paid four times more than its original price, and let him understand that the extra money could buy more and better things Boyle was born in a noble family in Ireland on January 25, 1627. His father was a count and his family was rich. He is the youngest of fourteen brothers. Boyle was not very smart when he was a child. He stuttered and didn't like lively games, but he was very studious and liked to read and think quietly From 1639 to 1644, he traveled to Europe. During this period, he read a lot of natural science books, including the famous book dialogue about two world systems by Galileo, an astronomer and physicist. The book left a deep impression on him. His later famous work skeptic chemist imitated this book< Edison only went to primary school for three months in his life, and his knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up Edison was curious about many things since he was a child, and he liked to test them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style9. The story of Edison.

"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Edison murmured: "life is too short, too short. Save time and do more things!"< Before he became famous, Edison was a poor worker. Once, his old friend met him in the street and said with concern, "look, this overcoat on you is not in good condition. You should replace it with a new one."
"do you need it? No one knows me in New York Edison answered with indifference
a few years later, Eddie has become a great inventor< One day, Edison met his friend on the street of New York“ "Oh," exclaimed the friend, "Why are you still wearing this old coat? This time, you need a new one anyway
"do you need it? Everyone here already knows me. " Edison still answered with indifference
Nobel story
Nobel was very thin when he was a child. When he was ten years old, he went with his mother to bederburg, Russia, where he was reunited with his father and began to receive guidance from a tutor. At the age of 17, he went to the United States to study, and returned home two years later to work in his father's company
influenced by his father, Nobel was very interested in studying explosives. Later, he made a lot of money by manufacturing explosives and developing oil fields. However, when he saw that the explosive he invented was used in war, he felt very sad, so he devoted all his life to appealing to the world to use it for peace. Nobel set up a fund with his huge wealth and awarded prizes to people who have made outstanding contributions to physics, chemistry, biology, medicine, literature and peace in the world every year. To be able to win the Nobel Prize has always been regarded as a great honor
the laboratory was foggy and Nobel was working selflessly. His brother came to him and said, "Nobel, I'm sorting out the genealogy of our family. You are a famous person in the world. How can you do without your autobiography? Write an autobiography. "
"no, brother."
"how can I do that?" Nobel's brother advised, "brother, you write autobiography not for yourself, but for our family! You write it. Your autobiography will add luster to our family tree! "
when Nobel still disagreed, his brother repeatedly persuaded him. Finally, he even begged: "brother, are you afraid of wasting your time? In that case, you can talk about it and I'll record and sort it out. "
"it's hard for me to follow orders." Nobel's attitude is modest, but his tone is firm. "I can't write autobiography. There are so many planets with Ganges sand grains in the vortex of the universe, and we are insignificant. What's worth writing about?"
so it is! He thinks that what he has done is only for the sake of human beings. Why should he exchange a little contribution for honor. Therefore, he never agreed
Nobel's brother had to leave with a sigh. Nobel went back to experimenting
Nobel's will is the essence of his ideal and the crystallization of his heart and blood. Although he is very rich, he is unwilling to distribute his property to his relatives and friends. He thinks: a large amount of property is the bane of hindering human talent. Those who have wealth should only leave their children the necessary ecation expenses. If they leave too much money, it is a reward for laziness, so that they can not develop their talents
therefore, despite the opposition of his relatives and friends, he decided to use all his property to set up a Nobel Prize to reward the contemporary world elite< On May 30, 1974, Li Zheng was staying in Beijing hotel. At 6 o'clock in the morning, the telephone rang and said: Chairman Mao wants to meet him. Li Zheng didn't get up at that time, so he dressed and washed quickly. An hour later, he went to Chairman Mao's study in Zhongnanhai. After shaking hands with Li Zheng, Chairman Mao asked as soon as he was seated: "why is symmetry important? Symmetry is balance and balance is stillness. It's not static, it's dynamic. "
according to Wechsler's dictionary, symmetry means "balanced proportion", or "beauty of shape resulting from such balanced proportion". In Chinese, symmetry means "symmetry", which has almost the same meaning. Therefore, this is essentially a static concept. According to Mao Zedong, the whole evolutionary process of human society is based on "dynamic" changes. Dynamics, not statics, is the only important factor. Mao Zedong insisted that this must also be true in nature. Therefore, he could not understand that symmetry would be held so high in physics
at the meeting, Li Zheng was Chairman Mao's only guest. Between their chairs was a small table with notebooks, pencils and green tea, which was often used to entertain guests. Li Zheng picked up a pad from the tea table, put a pencil on the book, and then tilted the book toward Mao Zedong, and then toward himself. This pencil rolls back and forth on the book. Li Zheng repeated this three times. Then he said, "Madam President, the process of my movement just now is symmetrical, but no moment is static." Li Zheng explained that symmetry is not a simple balance, and it may also be symmetry in motion. The concept of symmetry is by no means static. It is more general than its usual meaning, and it is applicable to all natural phenomena, from the birth of the universe to every microscopic subnuclear reaction process. Chairman Mao is very interested in what is symmetry. He said that all his life he has experienced turbulence, so he thinks that movement is important. When he was young, he didn't have much time to study science. Most of his ideas about science came from a set of "outline of science" written by Thompson. Their conversation lasted about an hour
later, Li Zheng left China to return to the United States. On the plane, a waiter gave him a bag of things, saying that it was given by Chairman Mao. When Li Zheng opened it, he found that it was a package of books. It was the set of science outline mentioned by Chairman Mao. It was in four original English versions, and it was the first edition. At that time, this edition could not be found. Now this set of books is still kept in Li Zheng's study< Einstein, a world-class great scientist, has always felt guilty for his "biggest mistake in his life". What did Einstein do wrong
in 1917, the second year after he founded general relativity, Einstein and Dutch physicist de Sitter independently carried out this work in order to explain the stability of the universe. They found that the universal solution of the gravitational field equation is dynamic rather than static. That is to say, the universe either expands or contracts. Because of the bias of physical intuition and the error of mathematical operation, Einstein never gave up the concept of static universe. In order to get a static solution of the universe model, he did not hesitate to introce a "universe term" into the equation. At that time, this conclusion was consistent with both cosmological principles and known observational facts. However, in 1922, the American scholar Friedman found another dynamic solution of the equation; In 1927, the Belgian scholar Le mett independently obtained the same solution. It is proved mathematically that the universe is not static, but expanding or contracting evenly. However, Einstein still refused to accept this result and insisted on his view of static universe model
two years later, according to the observation of distant nebula, American astronomer Hubble found that the spectral lines of distant stars have red shift, and the farther away from the earth, the greater the red shift. That means the stars are moving away from the earth. Hubble's discovery supported Friedman's dynamic universe model and changed Einstein's view of the universe. Einstein called the mistake of sticking to the static model of the universe "the biggest mistake in his life" and withdrew his criticism of Friedman and others
later, on his 70th birthday, he told his friend solovin: "I feel that no concept in my work can stand firmly, and I'm not sure that I'm generally on the right path." To a large extent, this sentence contains his mistake in 1917
a world-famous great scientist has the courage to admit his mistakes and modestly review his achievements that have been recognized and praised by the world, which shows Einstein's magnanimous mind of seeking truth from facts and respecting science. That's why Einstein made great achievements. ekg

When Li Zheng opened it, he found that it was a package of books. It was the set of science outline mentioned by Chairman Mao. It was in four original English versions, and it was the first edition. At that time, this edition could not be found. Now this set of books is still kept in Li Zheng's study< Einstein, a world-class great scientist, has always felt guilty for his "biggest mistake in his life". What did Einstein do wrong
in 1917, the second year after he founded general relativity, Einstein and Dutch physicist de Sitter independently carried out this work in order to explain the stability of the universe. They found that the universal solution of the gravitational field equation is dynamic rather than static. That is to say, the universe either expands or contracts. Because of the bias of physical intuition and the error of mathematical operation, Einstein never gave up the concept of static universe. In order to get a static solution of the universe model, he did not hesitate to introce a "universe term" into the equation. At that time, this conclusion was consistent with both cosmological principles and known observational facts. However, in 1922, the American scholar Friedman found another dynamic solution of the equation; In 1927, the Belgian scholar Le mett independently obtained the same solution. It is proved mathematically that the universe is not static, but expanding or contracting evenly. However, Einstein still refused to accept this result and insisted on his view of static universe model
two years later, according to the observation of distant nebula, American astronomer Hubble found that the spectral lines of distant stars have red shift, and the farther away from the earth, the greater the red shift. That means the stars are moving away from the earth. Hubble's discovery supported Friedman's dynamic universe model and changed Einstein's view of the universe. Einstein called the mistake of sticking to the static model of the universe "the biggest mistake in his life" and withdrew his criticism of Friedman and others
later, on his 70th birthday, he told his friend solovin: "I feel that no concept in my work can stand firmly, and I'm not sure that I'm generally on the right path." To a large extent, this sentence contains his mistake in 1917
a world-famous great scientist has the courage to admit his mistakes and modestly review his achievements that have been recognized and praised by the world, which shows Einstein's magnanimous mind of seeking truth from facts and respecting science. That's why Einstein made great achievements. ekg
10. The story of Edison
Edison only went to primary school for three months in his life. His knowledge came from his mother's teaching and self-study. His success should be attributed to his mother's understanding and patient teaching since childhood, which made Edison, who was originally regarded as an incompetent child, become a world-famous "king of invention" when he grew up
Edison was curious about many things since he was a child, and he liked to experiment with them himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his own interests. He set up a laboratory in New Jersey and invented more than 2000 kinds of things in his life, such as electric lamp, telegraph, phonograph, video camera, magnetic separator, crusher and so on. Edison's strong research spirit made him make great contribution to the improvement of human life style
"waste, the biggest waste is to waste time." Edison often said to his assistant“ Life is too short. Think more and do more with less time. "
one day, Edison was working in the laboratory. He handed his assistant an empty glass bulb without a light port and said, "you measure the capacity of the bulb." He bowed his head to work again
after a long time, he asked, "what's the capacity?" He didn't hear the answer. He turned his head and saw his assistant measuring the perimeter and inclination of the bulb with a tape measure. He took the measured number and put it on the table to calculate. He said, "time, time, how do you spend so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to his assistant, and said, "pour the water in the measuring glass, and tell me its capacity right away."
the assistant immediately read out the number
Edison said, "what an easy way to measure. It's accurate and time-saving. Why can't you think of it? Is it not a waste of time? "
the assistant blushed
Newton, known as the pioneer of modern science, has made great contributions to science. His three great achievements, the analysis of light, the law of gravitation and calculus, have laid the foundation for the development of modern science
Why did Newton make great achievements in science? How did he become a great scientist from an ordinary man? To answer these questions, we can't help but think of several stories about his hard study and hard work
"I must surpass him!"
when it comes to Newton, people may think that when he was a child, he must be a "prodigy", "genius" and had extraordinary intelligence. In fact, Newton's childhood was weak and his brain was not smart. When I was studying in my hometown, I didn't study very hard, and my grades in class were inferior. But his interest is extensive, and his ability to play is higher than that of ordinary children. Usually, he likes to make mechanical models, such as windmills, waterwheel, sundials and so on. He carefully made a water clock with accurate timing, which was praised by people
sometimes, he plays in a strange way. One day, he made a lantern and hung it on the tail of a kite. When night falls, the lighted lantern rises into the air by the rising force of the kite. Luminous lanterns in the air flow, people were surprised, thought that there was a comet. Nevertheless, because of his poor academic performance, he is often discriminated against<
at that time, the British hierarchy system in feudal society was very serious, and the good students in primary and secondary schools could discriminate against the poor students. There was a game between classes when everyone was in high spirits. A good student kicked Newton and called him a fool. Newton's heart was so irritated and angry. He thought, we are both students, why am I bullied by him? I must surpass him! From then on, Newton made up his mind to study hard. He gets up early and goes to bed late. He studies hard and thinks hard
after hard study, Newton's academic performance continued to improve, and soon surpassed the classmate who had bullied him and ranked at the top of the class< There are many famous scientists in the world whose families are poor. On the road to success, they all fought against the hardship. The circumstances of Newton's youth are also very sympathetic< Newton was born in 1642 at the home of an ordinary farmer in England. Newton's father died shortly before he was born. His mother remarried when he was two years old. When Newton was 14 years old, his stepfather died and his mother returned to his hometown. Newton was forced to leave school and go home to help his mother farm. His mother wanted to train him to make a living on his own and ask him to deal in agricultural procts< How reluctant a studious child is to leave his beloved school! He cried several times, but his mother didn't change her mind. At last, he had to learn to do business against her will. Every morning, he and an old servant went to a big town more than ten miles away to do business. Newton didn't like business very much. He entrusted all his affairs to his old servant, but he secretly went to a place to study
as time went by, Newton became more and more disgusted with business. All he liked was reading. Later, Newton simply did not go to the town business, only asked the old servant to go alone. Afraid that his family would find out, he went out with the old servant every day, stopped on the way and read under a fence. When the old servant came back in the afternoon, he would go home together
in this way, day after day, the reading life under the fence is endless. One day, he was reading happily under the fence when his uncle saw him passing by. Uncle a look at this scene, very angry, loudly scolded him for not doing his job; Grab Newton's book. My uncle was moved when he saw that what he was reading was a mathematics book with various marks on it. My uncle hugged Newton and said excitedly, "my child, just develop according to your ambition. Your right path should be reading."
after returning home, my uncle tried to persuade Newton's mother to abandon business and go to school. With the help of his uncle, Newton returned to school as he wished<
to study and calculate the wind force in a storm
time is the same to people, and gives people the same amount, but people use different time, and the knowledge they get is also very different< When Newton was 16 years old, his knowledge of mathematics was very superficial, and he didn't even understand the advanced knowledge of mathematics“ Knowledge lies in accumulation, intelligence comes from learning ". Newton made up his mind to climb the peak of mathematics by his own efforts. Under the unfavorable conditions of poor foundation, Newton could correctly understand himself and advance in the face of difficulties. He started from the basic knowledge and basic formula, and made solid progress step by step. After studying Euclidean geometry, he studied Descartes' geometry. In contrast, he thought Euclidean geometry was superficial, so he studied Descartes' geometry carefully until he mastered the essentials. So he invented the binomial theorem of algebra. It is said that Newton's story of "calculating wind force in a big storm" can prove Newton's body mechanics. One day, there was a big storm. The wind is blowing in the wild, the st is flying, and the mystery is long, which makes it difficult to open one's eyes. Newton thought it was a good opportunity to study and calculate the wind accurately. So he took the equipment and ran back and forth in the storm alone. He was staggering and struggling to measure. Several times the st lost his eyes, several times the wind blew away the paper, several times the wind made him have to stop working, but did not shake his desire for knowledge. Over and over again, he finally got the right data. He was so happy that he ran home to continue his research. Where there is a will, there is a way. After hard study, Newton laid a solid foundation for his scientific tower. Soon Newton's mathematical tower was built. He invented differential calculus at the age of 22 and integral calculus at the age of 23< When Newton was twenty-three years old, the plague spread in London. Cambridge University, in order to prevent students from being infected, has ordered students to suspend school and go home to avoid the epidemic. Newton returned to his hometown, rural Lincolnshire. During his stay in the countryside, he never stopped studying and researching. The basic work of the invention of gravitation, calculus, light analysis, etc. was completed ring this period
at that time, the children in the countryside often used a sling to hit the stones for a few turns and then threw them far away. They can also force a pail of milk around their head without the milk falling off
these facts made him doubt: "what power can keep the stone in the catapult and the milk in the bucket from falling? On this issue, he thought of the ideas of Kepler and Galileo. From the vast space, the endless planets, the cold moon to the huge earth, he thought of the interaction of forces between these giants. At this time, Newton plunged into the calculation and verification of "gravity". Newton plans to use this principle to test the laws of the planets in the solar system. He first deced the distance between the moon and
the earth. According to theory, the centripetal acceleration of the moon around the earth should be 16 feet per minute, but it is only 13.9 feet. In the plight of failure, Newton did not lose heart and discouraged, but with greater efforts to study hard. After seven years of cold and heat in spring and autumn, at the age of 30, he finally proved the world-famous "law of universal gravitation", laying the foundation for theoretical astronomy and celestial mechanics
ring this period, Newton also studied optics and discovered the origin of color. Once, no matter how he adjusted the lens, his viewpoint was always unclear when he was observing celestial bodies with his homemade telescope. He thought it might have something to do with the refraction of light. And then we started experimenting. He left a small round hole on the window of the darkroom for light transmission, put a prism behind the window, and hung a white screen behind the prism to receive the light folded through the prism. As a result, Newton was surprised to see that the refraction received on the white screen was oval, and the two ends
showed colorful colors. Newton thought deeply about this strange phenomenon. The white light of the sun is red, orange, yellow, green, blue, indigo and purple. Therefore, white light (sunlight) is a combination of red, orange, yellow, green, blue, indigo and purple light. In nature, it is sunny after rain, and the sunlight is refracted and reflected by the raindrops in the sky, forming colorful iridescence
after further research, Newton pointed out that everything in the world has color, not its own color. The sun shines on all things, each object only absorbs the color it accepts, but reflects the color it cannot accept. The reflected color is the color of various objects that people see. This theory accurately reveals the origin of color, and all kinds of color theories in the world since ancient times have been overthrown by it
that's why Newton was able to achieve such a great success
