Today (March 20, 1727) is the Memorial
Day of the philosopher Isaac Newton, who studied extensively in the fields
of mathematics, mechanics, and gravity and was important in the scientific
revolution.
Sir Isaac Newton was born on Christmas Day, December 25, 1642, into an average farming family in Wollstorp, near Golsterworth, Lincolnshire, England. Her father died three months before she was born. Two years later Newton was left in the care of his grandmother and his mother moved in with her new husband. Her childhood was unhappy and restless. He joined the school at the age of 12. He was a very backward normal student in school. Instead of studying at school, he was interested in drawing and graduating. But at the age of making fun of himself, he began to read better, gaining self-confidence after marrying a boy older than himself. Newton was involved in science from an early age.
He also developed a clock that works on the water at an early age. When he was fourteen, he had to drop out of school due to family poverty. His uncle, aware of Newton's desire for education, enrolled him in 1661 at the prestigious Cambridge University in England. There he excelled in mathematics and physics and became an outstanding student. While studying at university he discovered mathematical formulas and binomial series theorems. He discovered the mathematical system of differential arithmetic and summative arithmetic, which is powerful enough to know nature. This discovery helped to apply the mathematical method in physics. The teaching of the college at that time was the same as that of Aristotle. But he also wanted to study the concepts of modern philosophers of the time, such as Newton, Descartes, Galileo, Copernicus and Kepler.
He graduated in 1665 with a bachelor's degree. After he graduated, the university was closed due to the plague. As he stayed at home for the next two years, he explored calculus, optics, and gravity. Within two years of his graduation, his scientific brain began to function immensely. He discovered various elements of modern mathematics. Divisions of modern mathematics such as the generalized binomial theorem and the infinitesimal calculus are his discoveries. He devised methods to find the area of curved objects and the capacity of solid objects. He turned his research to astronomy in 1664. That is, he began to engage in research on the planets in the sky. He began to think seriously about how the thin strips around the moon formed. He experimented with the difference between this beam of light and the beams of light in a rainbow. Many were amazed at his findings. The officers who saw his research knowledge offered to pay him a stipend. He put forward his ideas according to Kepler's arguments about the planets and succeeded in doing so. But before Newton, many scientists published the results of research on the position of the planets. Newton continued his research behind their research.
Although many believe that Newton was the first to discover the gravitational pull of the earth, even before that, many discovered that objects fall down due to the pull of the earth. However, Isaac Newton was the first to discover that this gravitational force is responsible for the motion of the planets and that the velocities vary in motion relative to how far away the planets are from the Sun. If his friend Waldo had not written notes about Newton, we would not have known about Newton's apple pie. One day Newton was sitting in his garden studying. Then an apple fell from the apple tree there. Newton's thought when he saw it went to the apple tree. Then what was the reason he fell from the apple tree and the apple came straight to earth and fell? He wondered why the fruit did not go on the tree. So he realized that the earth was taking over not only ordinary objects but also the planets. The event that caused him to think that day was due to the invention of motion and the canon of planetary rotation bound by the law of gravity.
He concluded that the key to the planet's orbit around the sun was causing the apple to fall from the tree. At the age of 24, he became famous in 1666 for publishing the Law of Gravity. In 1667, at the age of 25, he was appointed professor of physics at Newton Trinity College. He was given honorary responsibility at Trinity College. His friend Dr Barrow resigned from his post. When a discussion of mathematics arose, Dr Barrow was amazed to see the notes that Newton had already written. In it, Galileo had clearly explained the great things that had been left halfway through. Newton spent his days and nights researching the distances of the planets, which vary many times over, and how that force pulls them together. He was conducting this research in Lincolnshire. He was unable to continue the research because the place was uncomfortable. Knowing the shape of the earth and its circumference, he calculated the planets. He had not been engaged in any other work for two years.
"Patience in thinking and active effort are the main reasons for my success. I have no other thought than this," he said. Newton's first law stated that an external force is essential to move a stationary object, and that force is essential to change the motion of an object. The second rule is that when an object changes its position, the object changes speed and direction in the same direction according to the magnitude of the force.
For each reaction, an equivalent reaction occurs from the opposite direction. The two forces, which appear to be working opposite each other, stand in equal measure and determine the course of the object. The third rule explains that since one force is not separate, it is always two-open. When we push an object by one type of force, another force is placed on it against that force and obstructs our force. In 1687 he published Philosophiae Naturalis Principia Mathematica, a treatise on gravity. Through his laws of motion, he introduced the field of classical mechanics. Not bright co-founded Wilhelm Leibniz with the development of the field of differential calculus. In Newton's Principia itself, the next three centuries saw the emergence of the laws of motion and general gravity, which dominated the scientist's view of the physical universe. It explained that the motions of objects on Earth and the motions of objects in outer space, such as planets, could be described based on the same principles.
He discovered the effects of light falling on a triangle called a prism. He explained in the recipe that when the sun's light passes through a prism, it splits into seven colours. He also showed that when a multi-coloured Newton's disk rotates, it turns white. He was the first to describe white light as a combination of multi-coloured light. He closed one eye and stared at the sun with the other eye to research the colours. Suddenly the colours began to change. As a result, Newton suffered damage to that eye. I had to remove the floating spots in front of the eyes from the darkroom for several days. The emission theory of light was laid down by Newton. The theory is that light is visible only when particles emitted from a distant glowing object journey at a speed of one hundred and ninety thousand miles per second in space.
He is also notable for his claims that light is made of cloth. Wave-fabric duality is defined as the force of gravity between two particles is inversely proportional to their masses and inversely proportional to the gap between them. He studied the nature of light in-depth and focused on the development of telescopes. He also made telescopic glasses that were six inches long and one inch in circumference. In one year he also built a telescope. Thereby he was able to see the moons of Jupiter Cole. Today's modern telescopes are based on Newton's first telescope. The spectacle he invented is still in the Royal Society of London.
When he was working at Trinity College, he was 51. He had it all on the table to publish all of his notes as a book. Newton's dog then fought the rat, seeing a mouse bite and destroy the notes. Then the candle that was burning next to it fell on the note and all burned to ashes. Without any anger at Newton's dog returning to the temple, he asked, "Did you see what had happened?" Newton's mind was greatly disturbed by the complete destruction of his lifelong collections of notes, and his friend Hayley, realizing that Newton had a wealth of knowledge, encouraged Newton to publish them all in a book, and in 1687 published the book "Mathematical Principles of Natural Philosophy". The book is considered one of the greatest science fiction books ever published.
At a special ceremony in Cambridge in 1705, Queen Annie honoured Newton with the title of "Sir." The vast ocean is invisible to my eyes. “Newton, who had gone to London to preside over a meeting of the Royal Society, returned home unwell. Isaac Newton, a philosopher who made important discoveries in the scientific revolution, died in England on March 20, 1727, at the age of 85. He was buried in the famous "Westminster Abbey" in London. He was engraved in the tomb as The Best and Invaluable Gem of Mankind. Although many pay homage to Newton, the tribute written by the Pope is profound. This saying is still engraved in Newton's birthday room! "Nature and its laws were in darkness, God ... Newton said let light be born".
