Sir isaac newton is an English physicist, mathematician, astronomer, natural philosopher and alchemist. His paper "Philosophy of Nature" was published in 1687. The universal gravitation and three laws of motion are described. These descriptions laid the scientific view of the physical world in the next three centuries and became the basis of modern engineering. By proving the consistency between Kepler's laws of planetary motion and his theory of gravity, he showed that the motions of objects on the ground and celestial bodies all follow the same laws of nature. Thus, the last doubt about the sun center was eliminated and the scientific revolution was promoted. Newton's law of motion is the general name of the three laws of motion put forward by isaac newton, and is regarded as the foundation of classical physics. Newton method is also called Newton-Raphson method. It is an approximate method to solve equations in real number domain and complex number domain. Methods The first few terms of Taylor series of function f(x) were used to find the root of equation f(x) = 0. About isaac newton's life, I don't know what kind of person I am in others' eyes. But in my own opinion, I am like a child playing by the sea. From time to time, I am complacent about finding a pebble smoother than usual or a shell more beautiful than usual, but I have not found the vast ocean of truth in front of me. -Newton Newton's diligent study Speaking of Newton, the pioneer of modern science, people may think that he must have been a "prodigy" and a "genius" with extraordinary intelligence when he was a child. In fact, Newton was weak and not smart when he was a child. When he was studying in his hometown, he didn't study hard and his academic performance in the class was relatively poor. But he has a wide range of interests and his game skills are higher than those of ordinary children. Newton liked to make mechanical models, such as windmills, waterwheels and sundials. The timing was accurate and won people's praise. Sometimes, the way he plays ball is also very strange. One day, he made a lantern to hang on the tail of a kite. When night falls, the lighted lanterns rise into the air under the rising power of kites. Luminous lanterns flow in the air, and people are afraid that it is a comet. However, due to his poor academic performance, he is often discriminated against. At that time, the hierarchical system in British feudal society was very serious, as well as in primary and secondary schools. You can discriminate against poor students in school. Once during the recess game, when everyone was in high spirits, a student who studied very well kicked Newton and called him an idiot. Newton's heart was extremely angry with excitement. He thought, we are all students. Why should I be bullied by him? I must pass him! From then on, Newton made up his mind to study hard. He gets up early and goes to bed late, seizes every minute, studies hard and thinks hard. After studying hard, Newton's academic performance improved continuously, and he soon surpassed the classmate who bullied him and was among the best in his class. Time treats people equally and gives people the same amount, but people use time in different ways and gain different knowledge. When Newton was sixteen, his knowledge of mathematics was still superficial. I can even say that I don't know advanced mathematics. "Knowledge lies in accumulation, and intelligence comes from learning." Newton was determined to climb the peak of mathematics by his own efforts. Under the unfavorable conditions of poor foundation, Newton can correctly understand himself and make progress despite difficulties. He relearned the basic knowledge and basic formulas and made solid progress step by step. After studying Euclidean geometry, he studied Cartesian geometry. In contrast, he thinks Euclidean geometry is superficial. He studied Descartes' geometry carefully until he got the gist and mastered it. Then he invented the algebraic binomial theorem. Newton's legendary story of "calculating the wind force in a big storm" can prove Newton's body mechanics. One day, there was a big storm, the wind was howling and the dust was flying, making it hard to blink. Newton thought it was a good opportunity to study and calculate the wind accurately. So Newton thought it was a good opportunity to study and calculate the wind accurately. He ran back and forth in the storm alone, stumbling and struggling to measure. Several times the dust fascinated his eyes, several times the wind blew away the paper, and several times the wind forced him to suspend his work, but none of them shook his thirst for knowledge. He finally got the correct data over and over again. He was so happy that he hurried home to continue his research. Where there is a will, there is a way. After diligent study, Newton laid a scientific tower for himself. Newton's math tower was built. He invented differential calculus at the age of 22 and integral calculus at the age of 23, making great contributions to the cause of human science. Newton was a very modest man and never conceited. Someone once asked Newton, "What is the secret of your success?" Newton replied, "If I have a little success, there is no other secret but diligence." Young Newton1643 65438+1October 4th, Newton was born in a farmer's family in Walsop, Lincolnshire, England. Newton was a premature baby, weighing only three pounds at birth. The midwife and his relatives are worried about whether he will survive. No one expected that this seemingly insignificant little thing would become a giant of science and even live to be 85 years old. Newton's father died three months before he was born. When he was two years old, his mother remarried to a priest and left Newton to his grandmother. 1 1 years old, the mother's husband died. Mother returned to Newton with a son and two daughters born with her husband. Newton was taciturn and stubborn from childhood. This habit may come from his family situation. Newton has been sent to public schools since he was about five years old. Newton was not a child prodigy when he was a teenager. He has an average academic background and average grades, but he likes reading books and books introducing various simple mechanical model making methods. He was inspired and made some strange gadgets by himself. Such as windmills, wooden clocks and folding lanterns. It is said that Newton made a model of the windmill after understanding the mechanical principle of the windmill. He tied the mouse to a treadmill with wheels, and then put a corn in front of the wheel, just out of the mouse's reach. The mouse wants to eat corn, so it keeps running, so the wheel keeps turning. Once again, when he was flying a kite, he hung a small lamp on the rope. In the evening, the villagers were surprised to find that a comet appeared. He also made a small water clock. Every morning, a small water clock automatically drops on his face to wake him up. He also likes painting and carving, especially carving sundials. His sundial was placed in the corner of his house and everywhere on the windowsill to observe the movement of the shadow. Newton entered Grantham Middle School not far from home at the age of 12. Newton's mother had hopes for him. But he likes reading. As he grew older, Newton became more and more fond of reading, meditating and doing small scientific experiments. When he was studying in Grantham Middle School, he lived in a pharmacist's house, which influenced him by chemical experiments. Newton's academic performance in middle school is not outstanding, but he loves reading. He is curious about natural phenomena, such as the movement of colors and shadows. Especially geometry, Heliocentrism of Copernicus, etc. He also takes reading notes in different categories and likes to make ingenious gadgets, tricks, inventions and experiments. At that time, the British society was permeated with new Christian ideas, and two relatives of Newton's family were priests, which may affect Newton's religious life in his later years. From these ordinary environments and activities, I still can't see that Newton is a gifted child. Later, due to life reasons, his mother asked Newton to stop studying at home to support his family. But Newton buried himself in reading whenever he had the chance, and often forgot to work. Every time, his mother told him to go to the market with his servant and get familiar with the business of trading. He begged the servant to go to the street alone while he hid behind the bushes and read. Once, Newton's uncle became suspicious and followed him. Found his nephew lying on the grass with his legs stretched out, absorbed in studying a math problem. Newton's studious spirit touched his uncle, so his uncle persuaded his mother to let Newton go back to school and encouraged him to go to college. Newton went back to school and eagerly absorbed nutrition from books.
