Many books about Newton have introduced the legendary story of Newton and Apple: During 1665-1666, due to the prevalence of Kala-azar in Cambridge, the school was forced to close, and Newton, who just got his bachelor's degree from Cambridge, also returned to his hometown. One day, Newton was sitting under an apple tree reading and thinking. At this moment, an apple fell, which inspired Newton at once. But later, experts found that the apple didn't hit Newton. And Newton recalled in his diary that the apple didn't hit him. The 23-year-old student immediately thought that the apple must have been pulled down by the gravity of the earth. After years of hard work, he finally completed everything.

Newton's belief

A. "There is no doubt that the world we see, in which various forms are so colorful and various movements are so complicated, is nothing but the free will of God who guides and dominates everything." -see "Selected Works of Newton's Natural Philosophy" on page 158

B. "Now we can take a step closer to appreciate the beauty of this nature and indulge ourselves in pleasant meditation, thus arousing our love and worship for the great creator and master of all things more deeply. This is the most beautiful and valuable fruit of philosophy. If anyone can't see the infinite wisdom and good will of the Almighty Creator from these most sensible and perfect designs of things, then he must be blind, and if he refuses to admit these, he must be a crazy person without feelings. " -see "Selected Works of Newton's Natural Philosophy" on page 16

C. "... But as a devout believer, Newton carved a theological mark in his natural science work long ago. Newton's family has a strong religious atmosphere. His stepfather and uncle are priests, and his grandmother and mother who raised him are devout believers. The purpose of sending Newton to Cambridge University is to hope that he will be a priest in the future. In 1678, when Newton graduated from Cambridge, according to the general practice, he was supposed to accept the clergy. However, Newton publicly stated that in order to better "serve God", he would not accept the priesthood, and replaced it with the study of natural philosophy to prove the existence of God, thus winning the franchise of King charles ii of England. Therefore, in his scientific research, he reconciled science and theology everywhere. He said:' It is undoubtedly a matter of natural philosophy to talk about God from the appearance of things. Only by revealing and discovering God's cleverest and most ingenious arrangement of everything and the ultimate reason in scientific work can we know God. " -Excerpt from the preface to Selected Works of Newton's Natural Philosophy

D. "In Newton's later period, after he rose to the top in the capitalist world, the vacillation and compromise of the bourgeoisie completely dominated him, and he went further and further on the road of theology and idealism. He immersed himself in the study of alchemy and wrote a lot of notes and articles; He is keen on chronology and theology, trying hard to research the deeds in the Bible and the "scientific" age of ancient Greek and Egyptian legends, trying to prove that the ten horns on the head of the behemoth seen by the prophet Daniel in his dream are ten kingdoms, and one horn is the Roman church. He is also immersed in the study of the Revelation of John and so on. Among a large number of manuscripts left to his nephew-in-law, works on religion, theology and chronology reached 1.5 million words. These futile jobs occupied his whole later life, making him completely a slave to theology. In Newton's later life, the mainstream was idealism. Newton's natural philosophy can only find his final destination in God. " Excerpt from the preface to Selected Works of Newton's Natural Philosophy, pages 11-12

Personal evaluation of Newton's diligent study

When it comes to Newton, the pioneer of modern science, people may think that he must have been a "prodigy" and "genius" with extraordinary intelligence when he was a child. Actually, Newton's childhood was thin and his mind was not smart. When I was studying in my hometown, I didn't study hard, and my academic performance in my class was inferior. But his interests are extensive, and his game skills are higher than those of ordinary children.

Newton likes to make mechanical models, such as windmills, waterwheels and sundials. A water clock that he carefully made is accurate in timing and has won people's praise. Sometimes, the way he plays 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 by the rising power of kites. Luminous lanterns flow in the air, and people are frightened and think that there is a comet. Nevertheless, he is often discriminated against because of his poor academic performance.

Time treats people equally, giving them the same amount, but people use time differently and gain different knowledge.

When Newton was sixteen years old, his knowledge of mathematics was still superficial, and he even didn't understand advanced mathematics. "Knowledge lies in accumulation, and cleverness 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 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 felt that Euclidean geometry was superficial, so he carefully studied Descartes geometry until he mastered the essentials and achieved mastery. So he invented the algebraic binomial theorem. The legendary story of Newton's "calculating the wind in a big storm" can prove Newton's body mechanics. One day, there was a big storm. The wind is howling wildly, the dust is flying, and the mystery is long, making it difficult to open your eyes. Newton thought it was a good opportunity to study and calculate the wind accurately. So, he took the appliance and ran back and forth in the storm alone. He stumbled and labored to measure. Several times the dust lost 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 desire 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 solid foundation for his mathematical tower. Soon, Newton's mathematical tower was built. At the age of 22, he invented differential calculus, and at the age of 23, he invented integral calculus, which made great contributions to the cause of human mathematics.

Newton was a very modest man, and he was 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, only diligence."

Standing on the shoulders of giants

Newton's research fields are very extensive. Besides making outstanding contributions in mathematics, optics and mechanics, he also spent a lot of energy on chemical experiments. He often stays in the laboratory for six weeks, working day and night. He spends a lot of time on chemistry, but he has hardly made any remarkable achievements. Why is the same great Newton so different in different fields?

one of the reasons is that various disciplines are at different stages of development. In mechanics and astronomy, with the efforts of Galileo, Kepler, Hooke, Huygens and others, Newton may build a magnificent building of mechanics with the prepared materials. As he himself said, "If I see far, it is because I stand on the shoulders of giants". In chemistry, because the right path has not been opened up, Newton can't go where he can cut down materials.

On his deathbed, Newton summed up his life in this way: "I don't know what kind of person I am in the eyes of others; But in my own opinion, I am just like a child playing at the seaside, complacent about finding a pebble smoother than usual or a shell more beautiful than usual from time to time, but I have not found the vast ocean of truth before me. "

this is of course Newton's humility.

The controversial Newton

When Newton was a student, he found a way to calculate infinite quantities. He used this secret method to calculate the hyperbolic area to 25 digits. He once bought a prism at a high price and used it as a tool for scientific research, and used it to test the decomposition of white light into colored light. Later, while studying, Newton compiled his research results for more than 2 years into a masterpiece with a thickness of more than 6 pages. Some people think that Newton's discovery is just a personal pastime, in order to amuse himself in the silent study.

When Newton was a university professor, he was often too busy to sleep and eat. He was thought to be slovenly, and he often walked into the restaurant with his tie and garter undone. It is said that in the process of proposing marriage to a girl, his mind had been distracted, and an infinite binomial theorem appeared in his mind.

When Newton was a child, there was a little girl who grew up together. Later, when Newton went to Cambridge to study, the girl married someone else. At this time, Newton was concentrating on his studies. Later, when the little girl divorced her husband and went to Newton, Newton felt deeply that his heart belonged to science and could not give her happiness, so he politely refused her with deep regret. After that, Newton never married.

Newton was good at observing various phenomena, even small things in daily life, and made important discoveries in the history of science. Because he was obsessed with scientific research, Newton often forgot to eat and sleep in his life. He once made a joke because he was too focused on research, and later it was passed down as an anecdote. Once, while reading a book, he boiled eggs on the stove. When he opened the pot and wanted to eat eggs, he found a pocket watch in it. On another occasion, he invited a friend to dinner. When the meal was ready, Newton suddenly had a flash of inspiration in his mind. He thought of a problem and immediately went into the study. His friend waited for him for a long time, but he still didn't come out, so he ate all the chicken himself, leaving the chicken bones on the plate without saying goodbye. When Newton remembered, he came out, saw the bones on the plate, thought he had eaten them, and turned and went back into the inner room to continue studying his problems.

alexander pope said:

nature and nature's laws lay hid in the night;

God said,"let Newton be!" And all was light.

Soon, everything returned back to the dark as ail

be there ...

Nature and its laws are hidden in the dark;

God said, "Let Newton be born!" So everything was illuminated.

mechanical unit

Newton, abbreviated as cow, is an international unit to measure the force.

Newton (symbol n) is the metric unit of force in physics. It was named after isaac newton, who founded classical mechanics.

Newton is a unit derived from the international system of units, which is composed of kg·m·s^? The basic unit of the international system of units of 2 is derived.

the force required to make an object with a mass of one kilogram obtain an acceleration of 1m/s 2 is defined as 1 Newton.
