Stories about celebrity observations and reflections are urgently needed

Thoughtful celebrity stories are:

1. Galileo discovered the pendulum principle.

One day, he was standing in the Catholic church in Pisa, his eyes fixed on the ceiling. He pressed his left hand with his right hand and looked at the lights that swayed back and forth on the ceiling.

He found that although the oscillation of the lamp was getting weaker and weaker, so that the distance of each oscillation gradually decreased, the time required for each oscillation was the same.

So, Galileo made a pendulum of the appropriate length and measured the speed and uniformity of the pulse. From here, he found the pattern of the pendulum. The bell was made according to this law that he had discovered.

2. Newton discovered gravitation.

One day, while Newton was walking, a ripe apple fell from a tree and hit him right on the head. This incident caused Newton to think deeply.

He thought: Why do apples have to fall to the ground? Why not take to the skies and beyond? He assumed that there was an attraction in the center of the earth, and that this attraction existed for any matter. Through his research, he discovered the law of gravitation.

3. Archimedes.

In Italy more than 200 years BC, there was a great scholar named Archimedes. One day, the king suspected that his crown made of pure gold had been manipulated by a craftsman, so he gave Archimedes the problem and demanded that the crown not be destroyed.

After his own meditation, he found that different objects in an overflowing tank overflowed with different amounts of water, which led to the famous Archimedes' principle.

4. Sima Guang smashed the cylinder.

A group of children were playing in the courtyard, a child stood on top of the big tank, fell into the tank and was submerged, the other children ran away, Sima Guang smashed the tank with a stone, the water flowed out, and the child was able to live.
