Newton's family was poor when he was a child, and his father died of illness long ago. Newton and his mother lived a poor life.

At the age of fourteen, Newton dropped out of school because his family couldn't afford it. After dropping out of school, his thoughts still stay in

Math book. One day, his mother asked him to ride a horse to the mountain on business. He took the saddle to the stable and led the horse. In fact, he is thinking about a math problem at the moment. When he was leading the horse out, he suddenly thought of a solution to the problem. He didn't lead the horse, but he thought as he ran with the saddle. After reaching the top of the mountain, another solution to the problem came up, but the horse had already run away without a trace, and only the saddle was still on his shoulder.

Newton devoted himself to mathematics and made many masterpieces in analytic geometry and calculus. He later became a famous mathematician.

Newton was introverted and ingenious when he was a child, but his grades in school were very poor. His mother changed it when he was young.

After getting married, he lived with his grandmother. Grandma found Newton very clever and invented many tools, such as small windmills and small ones

Castles and so on ... he put them in his small workshop.

Although Newton can make windmills and kites, he is inferior in every exam at school, so

I am often whipped by my teacher. Once, Newton made a windmill. When there is wind, the windmill turns very fast. newton

Think: Is there no wind energy in the windmill? He has been thinking. Later, he made it by stepping on a round cage with a mouse.

The windmill keeps turning.

Later, he didn't want to be looked down upon by other students, so he studied hard and got excellent grades. He was admitted.

He visited Cambridge University and made great contributions in mechanics, mathematics and optics.

Newton had a cat when he was a child, and his family told him to open a passage for the cat on the door. Newton made two holes in the door, one large and one small. The neighbors were surprised and asked Newton why he had to open two holes. Newton replied that the big cat went through the big hole and the little cat went through the small hole. However, I don't seem to know the simple truth of great power and small power, and it has been handed down as a joke since then.

The most popular version of this story is probably "If Newton is stubborn, a kitten can go through a big hole and there is no need to open it."
