If Newton hadn t been under the apple tree, what would physics have been?

In the text we learned in elementary school, it was said that Newton was sitting under a tree resting when he was hit on the head by an apple, and then he thought about the law of gravitation. When I read this article, I had this question in my mind, why did Newton come up with such a famous theory when he was hit in the head by something, but I couldn't think of it? In fact, when I grew up, I found that there was a big problem with the authenticity of this story.

The reason why I made up such a story is to tell us to be good at thinking in life, not whether Newton really came up with gravity after being hit on the head by an apple. <>

As one of the founders of modern physics, Newton can be said to have made many contributions in his lifetime. In addition to physics, Newton also had a lot of contact with mathematics, and our calculus was developed by Newton. From here, we can see that Newton was an extremely rigorous person, because those who engage in mathematics must pay attention to a process of deduction, so Newton will not directly say gravity because he was simply hit by an apple.

In the middle of this process, he must have gone through a lot of experiments to verify his own laws. <>

Just as Copernicus proposed heliocentrism, Galileo provided evidence for heliocentrism. Perhaps sometimes great physicists like them have no way to prove the correctness of their theories due to the limitations of the times. But as the times progress, there will always be someone who will help them realize their original conjectures.

Even if Newton hadn't been hit on the head by an apple to come up with gravity, his achievements in other fields alone would have made him famous for all eternity. <>

So we don't need to assume at all that Newton wasn't hit by an apple, it seems to me that even without this process, he would have recognized the gravitational pull that exists between objects. For they must have thought about such a question in their eyes, and have done some research in this area, and only on this basis can they be guided in the direction when they have a flash of inspiration.

I think that even if Newton had not stood under the apple tree, the path of physics would still be the same as we have today, mainly because he did not stand under the apple tree, he might still be standing under the peach tree, and gravity may be found under the pear tree.

A series of phenomena in physics will be discovered by other people and developed into what they are now, and nothing will change because of the lack of a person.

Newton's discovery of gravity when he was smashed by an apple is just a made-up story. In fact, Kepler's discovery of the three laws of planetary motion raises the question, what forces pull the planets to move in this way? At that time, Hooke proposed the hypothesis of gravitation, but he was not good at mathematics and did not derive a detailed formula.

Newton was also a great mathematician, and he quickly deduced the formula for gravitational force, which was completely consistent with actual astronomical measurements.

In fact, Newton's being smashed by an apple was only a very small thing, even in the physics world, even if Newton was not under the apple tree, there would always be something else that made him discover gravity.

Newton's apple and gravitational Newton's story.

Isaac Newton (1642-1727) was an English scientist. He discovered the law of gravitation, established the basic system of classical mechanics, and made creative contributions to optics, thermals, and astronomy, and was one of the founders of calculus in mathematics.

One night more than 300 years ago, a young man sat in a garden and watched the moon. He looked up at Somin's starry firmament, wondering why the moon orbited the earth instead of falling. Suddenly, something struck him on the head, a not-so-heavy blow that woke him from his contemplation.

He looked down and saw that it was a large, ripe apple falling from the tree. He picked up the apple and once again fell into deep thought: why didn't the apple fall to the sides, not to the sky, but to the ground vertically?

It must be that the earth has some kind of gravitational pull that directs everything towards the earth. The young man's eyes lit up: the same is true of apples, and the same is true of the moon, which must be moving at high speed under the attraction of the earth's gravity.

Because of gravity, it cannot move away from the earth; Because of the speed, so that it would not fall like an apple, the night was getting deeper, and the young man held the apple in his hand and smiled heartily. He was the British scientist Isaac Newton, who discovered gravity. This year, he was only 24 years old.

Universal gravitation. The sweaty apple has eyes and was actually hit It means that there is a chance of hitting *** 1

Newton discovered the law of gravitation from the apple falling to the ground.

The content of the law of gravitation: any two objects in nature are attracted to each other, and the magnitude of the gravitational force is proportional to the product of the mass of the two objects, and inversely proportional to the quadratic of their distance.

An overview of the law of universal gravitation: It was first proposed by Newton in his book The Mathematical Principles of Natural Philosophy, published in 1687. Newton used the law of gravitation not only to explain the motion of the planets, but also to point out that the moons of Jupiter and Saturn also had the same motion around the planets.

Stupid, gravity isn't strong enough! No matter how strong it is, at least it will smash his brain**.

If you stone, you won't find gravity.

Newton was the greatest scientist of all time, and his greatness transcended the realm of physics and mathematics, as well as the limits of borders and times. Many people may not have studied calculus or even written expressions for the law of gravitation, but they have more or less heard some stories about Newton. Elementary school students have heard the story of Newton boiling his pocket watch as an egg, and they also know the story of Newton and the apple tree.

There are many stories about Newton thinking under an apple tree, and an apple fell from the tree and hit Newton, which inspired Newton to discover the law of gravitation.

It is easy to deviate from the truth when the story is told too much, and there is no record of Newton being smashed by an apple in rigorous research. But the story has been taken as a prime example of Newton's serious delving into the problem, as the Leaning Tower of Pisa reminds us of Galileo. There are also a lot of questions that people deduce:

What if the apple hadn't hit Newton? What would happen if it wasn't an apple or a durian or a watermelon that hit Newton?

The discovery of the law of gravitation is not as simple as the story of the fall of the apple describes, there are rigorous observations, thinking, logical reasoning, mathematical analysis, and experimental verification, and it is impossible for a non-top physicist to discover the law of gravitation at that time. Before Newton discovered the law of universal gravitation, Copernicus proposed the heliocentric theory, Tycho gave an accurate record of the observation of the planets' positions, Galileo provided strong evidence for the heliocentric theory, and Kepler gave the three laws of planetary motion. Together, these major discoveries point to the law of gravitation, and it was Copernicus, Galileo, Kepler and other sages who opened the way for the discovery of the law of gravitation, not the apple that smashed Newton's head.

So, whether people use apples or durians, watermelons or papayas in their stories, Newton still discovers the law of gravitation with his ingenuity.

Taking a step back, even if Newton had not been born in history, there would have been other scientists in his time who would have come forward to discover the laws of gravitation, discover the three laws of mechanics, and invent calculus. When science develops to a certain extent, there will be corresponding scientific laws that are about to emerge. A scientist can't change the direction of science, and neither can an apple.

If Newton hadn't been under the apple tree, he wouldn't have discovered gravity. But there will always be people who will discover the law of gravitation, but it will only be delayed for a while.

Physics will still be what it is today, but it is only a matter of time before Newton's first law is not discovered so quickly.

If Newton hadn't discovered physics at that time, the emergence of physics would have been delayed by 100 years.

This hypothesis does not hold up, because the earth is attractive, and the process of falling apples cannot be spinning. While sometimes opportunities are in the hands of a few, it is difficult for the average person to come across them.

The law of gravitation will be discovered, which will change the current scientific theory and make the scientific and technical direction of the study clearer, and then Newton's first and second and third laws.

I think it's the same as it is now, because Newton's focus is that apples are falling. Instead of spinning, so as long as Newton hadn't been stoned to death, gravity would still be discovered.

a. The apple falling from the tree is affected by gravity and does not belong to the application of Newton's third law;

b. The use of the rocket to disturb the recoil is also the relationship between the action force and the reaction force, which belongs to the application of Newton's third law;

b. The octopus moves and rows in the water by using the action force and the ridge matching reaction force; Therefore, it belongs to the application of Newton's third law;

This question does not belong to the application of the third law of cattle slowing down the wilderness; Therefore, a

b. Question Analysis:

Analysis: aThe observation method is to systematically perceive, investigate and describe objective things in accordance with a certain purpose and plan, with their own senses and auxiliary tools, in order to discover and verify scientific conclusions. Therefore, it does not fit the topic;

b.Asking a question is an attempt to discover a biology-related problem from daily life, production practice, or study. Try to formulate these questions in writing or verbally.

Describe the conflict between known scientific knowledge and the problem found (must be a question"?). "Why do apples fall down and don't fly up?

Therefore, it is in line with the topic.

c.Making a hypothesis is about applying existing knowledge to come up with possible assumptions about the answer to a question. Estimate the testability of the hypothesis. Therefore, it does not fit the topic;

d.The experimental method is to use specific instruments and materials to discover or verify scientific conclusions through purposeful and step-by-step experimental operation, observation, recording and analysis. Therefore, it does not fit the topic;
