What happened to Apple s inspiration for Newton

It was Newton who saw the apple fall from the tree and wondered why the apple fell down and not up.

Became the inspiration for the theory of gravitation**.

It was Newton who was sleeping under the tree, and an apple hit him on the head, which made the old man angry, and the more he thought about it, the more angry he became, so an idea came out, why did the apple fall to the ground, why didn't it fall to the sky? Gravity comes out.

This is a story made up by Voltaire, an admirer of Newton.

Newton's idea of gravitation probably came from his study of alchemy.

Some say that this was done to disguise Newton's alchemical research and preserve his reputation as a scientist; Others believe that Voltaire is trying to make the public better understand, but it is still inconclusive.

The law of gravitation.

It is a law of interaction between objects, Newton in 1687.

discovered. Any object has a mutual attraction to each other, and the magnitude of this force is directly proportional to the mass of the individual objects and inversely proportional to the square of the distance between them.

Newton was able to discover the law of gravitation for many reasons, but the main reason was that before Newton, many astronomers were observing planets in the universe.

After the observation records of several astronomers, when Kepler was accumulated, he analyzed and summarized these observations and obtained Kepler's three laws.

The so-called Kepler's three laws refer to 1All the planets orbit in elliptical circles around the Sun, and the Sun is in the common focal point of all ellipses. 2.The direction of the planet.

Sweep an equal area in an equal amount of time. 3.The cubic of the semi-major axis of all planetary orbits and the cubic of the revolutionary period.

are all equal.

Although Kepler's three laws were regarded as iron laws at the time, the scientific community was never able to understand their principles, so Newton was very distressed and began to study them without sleep or food.

According to the History of Physics

It is recorded that when Newton discovered the law of gravitation, he was in a daze every day, eating in the cafeteria, and the rice bowl was in front of him. I went to the cafeteria to eat, but I went in the wrong direction. Some teachers were walking on the beach behind the campus when they saw some strange calculations and symbols.

However, while Newton was studying gravity, the Black Death broke out in London.

Newton's university was forced to close, and Newton had to return to the relative safety of the countryside to take refuge, but he did not stop his pursuit of truth during that time.

Newton was the first to argue that gravity is not just a force between planets and stars, but may be a universal attraction.

He was a firm believer in alchemy.

The idea that matter attracts each other leads him to assert that mutual attraction applies not only to large celestial bodies, but also to objects of all sizes.

However, although Newton proposed the theory of gravitation, he failed to come up with a formula for gravitation, because the "g" in the formula was too small, until 1798, when the British physicist Cavendish used the famous Cavendish torsion scale to accurately measure the value of gravitational constant.

On November 18, 2017, the Royal Society officially published the manuscript of "Newton's Life Memoirs" on its official **, and found that "Newton was hit by an apple" is false.

It's fake! In the manuscript of a friend of Newton's who is in the existing collection of the British royal family, it is written that Newton drank tea under the apple tree before telling his friend why the apple fell to the ground precisely because of the gravitational attraction that attracted him. Before that, Newton had already discovered and studied gravity.

The law of gravitation was not smashed by an apple. This is just a story made up by posterity. By the time Newton discovered the law of gravitation, he had already done countless experiments. In addition to apples, there were many other objects such as small iron balls, which inspired Newton.

In 1679, Newton and Hooke discussed that Newton said that the magnitude of gravity is constant, and Hooke believed that gravity is inversely proportional to distance, and it was later proved that Newton was wrong, and Newton did not discover gravity until this year, so when he was 22 years old, he was smashed by an apple and discovered that gravity was wrong.

The law of gravitation is Newton's thinking after being smashed by an apple, and even if the conclusion finally reached through various scientific research, later generations generally called the law of gravitation smashed by an apple.

The apple is just an introduction, and the law of gravitation is only reflected in the apple landing, and the most important factor in the proposal and establishment of this law is that the research experiment is confirmed.

The apple was just a fuse that triggered Newton's thinking about this problem, and its real appearance was all because Newton loved to learn, think, and study.

It's possible. Because this is how Newton was smashed, he slowly thought about this problem, and then thought about gravity.

Being smashed by an apple is of course a joke, but gravity is real.

It's true, you just ask Newton.

It's true, don't believe you to ask Newton

Newton sat under the apple tree when the apple fell on his head. Newton was inspired to discover the law of gravitation. This is a story that children of several years old know, and almost all of them describe Newton's discovery of the law of gravitation.

However, according to Hong Kong's "Ta Kung Pao" 20**, according to a manuscript recently published by the Royal Society, the bridge of Newton being hit by an apple seems to be a legend made up by later generations.

It would be nice if it was a durian that hit the head. - Seek adoption.

The Memoirs of Newton's Life was written by Newton's friend and his contemporary, the physicist William Strickley. The memoir was published in 1752 and the manuscript is treasured in the archives of the Royal Society, which was previously used only for academic research. After it was posted online on January 18, netizens found this memoir confirmed:

Newton did not get hit on the head by an apple, but saw it fall, a fortuitous event that led Newton to devote himself to a research that might otherwise have been put on hold. ”
