Newton was curious about apples.

Watt was also very curious about the steam made by kettle manufacturers, and finally invented the steam engine.

Einstein was withdrawn from childhood, liked to play with a compass and was very curious.

Galileo also discovered the simple pendulum out of curiosity by observing the swaying of the chandelier.

When Edison was a child, he watched hens hatch eggs and tried to hatch them all day.

There is such a plot in a TV series: the teacher draws a circle on the blackboard and asks what the circle looks like. Children in kindergarten have talked about dozens of kinds; Pupils speak more than a dozen; Middle school students speak eight or nine kinds; College students speak two or three kinds; People in society (including bureau-level cadres) dare not say anything because they dare not.

Things are exaggerated. But isn't that what happens when we "study"? The more you learn, the more you dare not imagine. The more you imprison yourself in dead knowledge, the more your thinking shrinks, and finally you become a person who dares not think and dare not say, so you are called "mature" by society.

At Cambridge University, Wittgenstein was a student of the great philosopher Moore. One day, Russell asked Moore, "Who is your best student?" Moore said without hesitation, "Wittgenstein." "Why?" "Because, among all my students, he is the only one who is listening to my class. He always looks confused and always has a lot of questions." Russell was also a great philosopher, and later Wittgenstein surpassed him in fame. Someone asked, "Why is Russell behind the times?" Wittgenstein said, "Because he has no more questions."

Wrong bottle

Justus von Liebig, a famous German chemist, introduced chlorine gas into seawater to extract iodine, and found that a reddish-brown liquid was precipitated in the remaining mother liquor. Although he was surprised, he didn't take it to heart. He arbitrarily thought it was just a compound of iodine and put a label on the bottle. It was not until a French scientist later confirmed that it was a new element bromine that Justus von Liebig suddenly realized. He therefore called this bottle "the wrong bottle" to warn himself.
