When Aristotle was seventeen years old, his father sent him to Plato's Academy in Athens to study. Because Aristotle was talented and hard-working, he was highly valued by his teacher Plato.

Plato was worried that Aristotle had gone astray, so he said to Aristotle: "I will put a rein on you." The implication is that Aristotle was quick in thinking and Unlike ordinary people, Aristotle could not become the person Plato expected without strict discipline.

Although Aristotle respected Plato very much, Aristotle had his own unique thinking and opinions on academic issues. Therefore, Aristotle has a famous saying: "I love my teacher, but I love the truth even more." In Plato's later years, Aristotle and Plato often quarreled because of their different academic views. After Plato's death, Aristotle stayed in Plato's Academy for another two years. When new leaders took office, Aristotle left Athens.

2. Aristotle’s Story: Failure and Frustration

In other words, when Aristotle was teaching at the Lyceum Academy in Athens, he often discussed the philosophy of life with his students. . Once, a student asked Aristotle: "Why do jealous people always feel depressed and depressed?" After listening to the student's question, Aristotle replied: "Jealous people always feel depressed." Not only does he have to bear his own failures and setbacks, but he also bears the success of others, so he always shows his frustration to others. ”

3. Aristotle’s story: Fill the entire ocean. Fill the hole

One day, Aristotle was walking on the beach by the sea. He saw a man ladling water from the sea and pouring it into a small hole he had dug on the shore. Aristotle was worried about his own problems. He didn't care.

Once, twice, he approached the man, but the man was so focused that Aristotle was curious: "What is he doing?" He couldn't control himself, and That man was absolutely focused. He walked to the seaside, filled a ladle of water, brought the water over, poured it into the hole, and then went to the seaside... Finally, Aristotle said: "Wait a minute, I don't want to disturb you." , but what are you doing? "

The man said: "I will fill this hole with the whole sea."

Aris. Dodd, even Aristotle, laughed. He said: "You are so stupid! This is impossible! You are just crazy. You are wasting your life! Just look at how big the sea is and how small your hole is - and with just a spoon, you Want to scoop the ocean into this hole? You are crazy! Go home and rest." The man laughed louder than Aristotle and said, "Yes. , I will go, because my work is done." Aristotle said: "What do you mean?"

He said: "You did the same - even more foolishly. Look at your head, it's smaller than my hole. Look at nature, it's bigger than the ocean. Look at your thoughts - are they bigger than my spoon? , and left laughing. Aristotle was stunned.

4. Galileo’s story: the world-famous falling body experiment

Before Galileo, Aristotle of ancient Greece believed that objects fall at different speeds. Its falling speed is proportional to its weight. The heavier the object, the faster it falls. For example, an object weighing 10 kilograms falls 10 times faster than an object weighing 1 kilogram.

On this day, he brought two iron balls of the same size but different weights. One weighed 10 pounds and was solid; the other weighed 1 pound and was hollow. Galileo stood on top of the Leaning Tower of Pisa, looking down. The bottom of the tower was full of people who came to watch, and everyone was talking about it.

Someone sarcastically said: "This young man must be mentally ill! Aristotle's theory can't be wrong!" The experiment began. Galileo held an iron ball in each hand and shouted loudly: He said: "People below, please see clearly, the iron ball is about to fall." After speaking, he opened both hands at the same time. People saw that the two iron balls fell in parallel and landed on the ground almost at the same time. Everyone was stunned. Galileo's experiments revealed the secret of falling bodies and overturned Aristotle's theory. This experiment has epoch-making significance in the history of the development of physics.

5. The story of Galileo: Staring at the ceiling

Once, he stood in the Catholic Church in Pisa, staring at the ceiling, motionless. What is he doing? It turned out that he was pressing the pulse of his left hand with his right hand and looking at the lamp swinging back and forth on the ceiling. He found that although the swing of the lamp became weaker and weaker, so that the distance of each swing gradually shortened, the time required for each swing was the same.

So Galileo made a pendulum of appropriate length and measured the speed and uniformity of the pulse. From here, he found the law of the pendulum. The clock was made based on this law he discovered.
