One day, more than 300 years ago, the famous British scientist Newton and his good friend Sttley went for a walk in the garden, and they walked to an apple tree and sat down to rest. Suddenly, a large apple fell from the tree and hit Newton's head. Newton was stunned for a moment and fell into deep thought:

Why don't apples fly into the sky, not to the sides, but to fall vertically? Why do objects thrown upwards end up falling downwards? Probably the earth has some kind of attraction, right?

Newton was very interested in this question, so he got into trouble with Stlerley. Then he returned to the laboratory and studied it carefully, and after several experiments, he finally found the problem. He said:

It seems that there is a mutual attraction between all objects in the universe, which we call 'gravitational force'. He continued his efforts and eventually discovered the law of gravitation.

Once, when Newton went on a trip to the countryside, he rested under an apple tree when suddenly an apple fell from the tree. He wondered why apples were falling from the top and not from the bottom up. He returned home with this question in mind, and later he discovered that the earth has a gravitational pull that can attract objects.

Subsequently, Newtonian Physical Gravitational Mechanics appeared.

Newton discovered, as in the science books there are, p. 41, the Earth-Moon system.

It was Newton who discovered the law of gravitation, not Kepler, Galileo, and Einstein

In 1849, according to Newton's discovery of the law of gravitation, scientists found that there was an unknown planet outside Reedus, and calculated the orbit of the planet Soon, the planet that was later named "Neptune" was discovered in the orbit of **

So the answer is: Newton, Neptune

In England, there was a young man named Isaac Newton, who studied physics. Newton was very good at thinking and often thought deeply about some very ordinary phenomena.

One day, he was resting under an apple tree when a ripe apple fell and hit him on the head. When Newton touched the place where he was injured, he thought of a question: when he threw the ball into the air, why didn't the ball always go up, but always go down?

Newton picked up the apple and suddenly had a strange idea. Is there an invisible force at work that drags the apple to the ground? After a long time, Newton finally solved this problem and derived a formula, the law of universal gravitation.

He believes that every object in the world has an invisible attraction to attract other objects. Heavy objects are more attractive than light ones. The Earth we live on is much bigger and heavier than everything on Earth.

So all objects thrown upwards will eventually fall to the ground. This is the result of the gravitational pull of the Earth.

Newton's discoveries could explain not only physical phenomena on Earth, but also phenomena between the universe and celestial bodies. Outside of Earth, there are many other planets like the Sun, Moon, Mars, and Jupiter, all of which are attracted by gravity, so the Moon revolves around the Earth and the Earth revolves around the Sun.

It is this gravitational pull that holds them in their respective positions so that, although they move under the same sky, they do not collide.

The little apple was a great inspiration to Newton. In fact, the same phenomenon has long been commonplace in the eyes of others, but others don't take it seriously. Only Newton discovered the law of gravitation through his own thinking.

Extended Materials. The Newton apple tree is a symbol of the spirit of scientific inquiry, inspired by the gravitational pull of the British science giant Newton's fall from the tree. In fact, this is a legendary story in the history of science.

The apple tree, which enabled Newton to understand the law of universal gravitation, became famous and is regarded as a symbol of the spirit of scientific inquiry.

Isaac Newton was a great British mathematician, physicist, astronomer, and natural philosopher whose fields of study included physics, mathematics, astronomy, theology, natural philosophy, and alchemy.

Newton's major contributions include the invention of calculus, the discovery of the law of universal gravitation and classical mechanics, the design and actual construction of the first reflecting telescope, etc., and is known as the greatest and most influential scientist in human history. In honor of Newton's outstanding achievements in classical mechanics, "Newton" later became a physical unit to measure the magnitude of force. ‘

1. The law of gravitation was published by Isaac Newton in 1687 in the Mathematical Principles of Natural Philosophy.

2. The law of gravitation is the law of gravity that explains the interaction between objects. The law states that any two particles are attracted to each other by a force in the direction of the concentric line. The magnitude of this gravitational force is directly proportional to the product of their masses and inversely proportional to the square of their distance, independent of the chemical nature or physical state of the two objects and the intermediary matter.
