Is it true that Newton was smashed by an apple and realized that gravity exists?

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.

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

To be precise, Newton discovered gravity not because of the fall of the apple, but because of his habit of thinking. It is able to think deeply about these ordinary things, so that he can see things that ordinary people can't.

Newton discovered gravity because of the fall of an apple? This is not the case.

It wasn't like that, he had noticed it before the apple fell. He has also done a lot of research on this.

It is almost certain that it was invented by Voltaire, or hearsay.

The great physicist discovered the famous gravitational repentance fiber after an apple fell and hit his head, which helped inspire young students to follow Newton's example and explore and think about physics. Is that really the case? When someone asked Newton himself for a copy, Newton laughed but didn't answer.

Through our understanding of Newton's life, the history of physics, and the knowledge of physics, we boldly speculate that Newton did not discover the famous gravitation force because the apple fell and hit his head, but Newton figured out that the force between the stars and the stars in the vast universe (gravitation) is the same force that forces the apple to fall on the earth.

And I suspect that Newton himself may have mentioned this at one point, using the example of an apple drop. Later, according to hearsay, with one pass to ten, it became Newton's discovery of the famous gravitation because the apple fell and hit his head.

Newton's discovery of gravity was due to the great developments and brilliant achievements of astronomy and mathematics, such as his predecessor Copernicus.

and Brulow, who proposed the heliocentric theory and discovered the three laws of celestial motion; Take Galileo, for example.

The invention of the telescope made it possible to make more accurate astronomical observations.

Newton was the master of physics and mathematics of his time, and created things like the discovery of calculus, the discovery of the three laws and the formula of universal gravitation.

The foundations of classical physics were laid.

Isaac newton.

4 January 1643 – 31 March 1727), Sir Cir, President of the Royal Society, a famous English physicist, an encyclopedic "all-rounder", and the author of "Mathematical Principles of Natural Philosophy".

Optics. In his 1687 book The Laws of Nature, he described the gravitation force and the laws of the three major motions. These descriptions laid the foundation for the scientific view of the physical world for the next three centuries and became the basis of modern engineering.

He did this by demonstrating Kepler's laws of planetary motion.

The consistency with his theory of gravity shows that the motion of terrestrial objects and celestial bodies follows the same laws of nature; It provided strong theoretical support for the heliocentric theory and promoted the scientific revolution.

In mechanics, Newton clarified the principle of conservation of momentum and angular momentum and proposed Newton's laws of motion.

Optically, he invented the reflecting telescope and developed a theory of color based on the observation that a prism diverges white light into the visible spectrum. He also systematically formulated the law of cooling and studied the speed of sound.

In mathematics, Newton shared the honor of developing calculus with Gottfried Wilhelm Leibniz. He also proved the generalized binomial theorem.

The "Newton's method" was proposed to approximate the zero point of the function and contributed to the study of power series.

In economics, Newton proposed the gold standard.

Newton once went to the mountains and suddenly an apple fell on him, and Newton wondered: Why did the apple fall and not fly to the sky? It turned out to be the gravitational pull of the earth, not that it flew into the sky.

As we all know, it is a legendary story that Newton was smashed by an apple. And behind this story, there is an important scientific discovery hidden - gravity. So, why was Newton able to discover gravity through this event?

First of all, we need to understand that Newton had already studied the laws of motion in depth before this event. He discovered that the state of motion of an object can be described by three fundamental quantities: mass, acceleration, and force.

At the same time, he has also verified the law of inertia and the law of action-reaction through experiments. These studies laid the groundwork for later discoveries.

Then, when the apple hit Newton, Newton began to think about the cause of this phenomenon. He discovered that the reason why the apple fell was the gravitational pull of the earth. At the same time, he realized that this gravitational pull is universal, not just between the Earth and the Apple.

Newton then began experimenting and reasoning, culminating in the law of universal gravitation. He believed that there is a force between all objects that attracts each other, and that the magnitude of this force is directly proportional to the mass of the two objects and inversely proportional to the square of the distance between the two objects. This law became an important foundation in the later development of physics.

Newton was able to discover gravity through the event when an apple hit him, because he had previously studied the laws of motion in depth and had a high scientific mind and observational power. The occurrence of this event also provided him with an opportunity to think about gravity. Behind this story, it also inspires us to have a scientific spirit, observe the world in daily life, discover problems, and expand our knowledge.

Newton's story.

One evening, a pensive Newton subconsciously walked towards the apple orchard in his backyard. In the garden, the apple trees were full of ripe apples, and the air was filled with a refreshing fruity aroma that Newton was completely unaware of.

Suddenly, there was a "click" sound, and a ripe apple on the tree was blown to the ground by the wind. Newton's train of thought jumped: Huh! Why don't apples fall into the sky? Could it be that the Earth's gravitational pull is attracting it?!

Newton immediately made associations and generalized them. It is thought that the force of the earth to attract apples is the same as the force of the earth that makes the moon revolve around itself, and the force of the sun that revolves the planets around itself. Gravity was derived, and people called it "gravitational force".

From a text I read in elementary school, I told the story of Newton reading under an apple tree and being hit by an apple, which inspired him to discover gravity.

Thanks to the almighty Internet for helping to clarify and find the source of the story - it turns out that Newton was not smashed by an apple at all:

It turns out that the story is like this! When I was a child, I used to look forward to having an apple tree on my doorstep and being hit by a ripe fruit to invent a great invention comparable to gravity. Now, I walk under apples, pineapples, durians, and coconut trees, and I never wait to be smashed again.

On the contrary, because Archimedes had an epiphany and discovered buoyancy when he was bathing, and because Kekule found a benzene ring when he was sleeping, he also expected to gain an epiphany while bathing and sleeping, so as to become a person who changed the world. Often depressed is:

It wasn't until I saw this American Malcolm book "Epiphany" that I found out:It turns out that capturing inspiration is a technique. It's never just about taking a bath, sleeping, and playing with an iPhone.

The book says: Since epiphany is everywhere, why do most of us always seem mediocre and rarely have a flash of inspiration? It is probably caused by the two grandsons of the barricade

An epiphany is a completely new idea caused by a particular state that helps to put oneself into practice, thus revealing a new experience and a higher level of awareness of the old, which is very rewarding. Only in this way can it be countedEpiphany

Have you ever had such an experience? When faced with a problem, you can't get rid of it after thinking about it for a long time, and finally suddenly it is like being struck by lightning, illuminating the blind spot, so you have a new discovery, this discovery makes you feel that everything becomes clear, and in an instant, the problem that has been bothering you for a long time is solved at once, and you feel surprised, satisfied, happy and full of satisfaction. If you have experienced such euphoria, you must be very eager to obtain this kind of epiphany in the future when you encounter difficulties, right?

Even if you don't have this experience, it doesn't matter, we can find a way to get it from this book "Epiphany".

There is a sentence in the book about epiphany:

When something goes to the technical level, we can break it down in detail so that we can prepare, prepare ourselves, and get into the state better. This kind of epiphany preparation is the same as a slam dunk practicing three-point shooting

This technical epiphany preparation consists of three steps:

It is a very pleasant thing for a person to have a well-thought-out experience, to have an epiphany experience, to gain inspiration. The book "Epiphany" makes three suggestions on individual epiphany to help individuals prepare for epiphany:

The way to epiphany is in it.
