My "pursuit" has its limits in life, and knowledge has no limits. There is no absolute truth in the world, only those who absolutely pursue the truth. Constantly pursuing the truth is more noble than possessing the truth

Eye staring 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.

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. Since more than 1,700 years ago, people have regarded this theory that goes against the laws of nature as an undoubted truth. The young Galileo boldly questioned Aristotle's theory based on his own empirical reasoning. After careful consideration, he decided to conduct an experiment himself. He chose the Leaning Tower of Pisa as his experimental site. On this day, he brought two iron balls of the same size but different weights. One weighed 100 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 took an iron ball in each hand and shouted: "People below, You see clearly, the iron ball is about to fall." After saying that, he opened his 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. Gajsenileo's experiment revealed the secret of falling body motion and overturned Aristotle's theory. This experiment has epoch-making significance in the history of the development of physics.

Leonardo da Vinci painted eggs Leonardo da Vinci, a famous painter during the European Renaissance, loved painting since he was a child. His father sent him to Florence, a famous city in Italy at that time, to learn from the famous painter Frochio. The teacher asked him to start by painting eggs. He painted one after another for more than ten days. Seeing that he was a little impatient, the teacher said to him: "Don't think that drawing eggs is easy. You must know that no two eggs in 1,000 are exactly the same; even if it is the same egg, just change the angle to see the shape." It would be different, and the oval outline of the egg would be different. Therefore, to express it perfectly on the drawing paper, it was necessary to work hard." From then on, Leonardo da Vinci studied sketching carefully and worked hard for a long time. With his artistic practice, he finally created many immortal paintings.

Sun Kang Yingxue Night Reading Sun Kang, a native of Jin Dynasty, came from a poor family but loved reading. At night, although I had time, I couldn't afford lamp oil, so I had to silently recall and digest the knowledge I learned during the day. One winter, he woke up in the middle of the night and felt that the room was not completely dark, and he could vaguely see some things. It turned out to be caused by the reflection of the white snow. This inspired him: why not use the snow light to read a book? So snowy nights, especially snowy nights illuminated by moonlight, became a good time for Sun Kang to study hard. Because of his diligence and studious, he finally became a famous scholar and became a censor.

"Lu Yu Abandoned Buddhism and Followed Literature"

Tang Dynasty Lu Yu, a famous scholar from the DPRK, was an orphan since he was a child and was raised by Zen Master Zhiji. Although Lu Yu was in the temple, he did not want to chant sutras and chant Buddha's name all day long. Instead, he liked to read poems and books. Lu Yu insisted on going down the mountain to study, but was opposed by the Zen master. In order to pose a problem to Lu Yu and educate him better, the Zen master asked him to learn how to make tea. In the process of studying tea art, Lu Yu met a kind-hearted old woman and not only learned the complicated tea-making skills, but also learned many principles of reading and life. When Lu Yu finally brought a cup of steaming Kuding tea to the Zen master, the Zen master finally agreed to his request to go down the mountain to study. Later, Lu Yu wrote the widely circulated "Tea Classic" and carried forward the tea culture of the motherland!

In the late Eastern Han Dynasty, Cao Cao "held the emperor to order the princes", which was regarded as National thief. A famous Luoyang doctor named Ji Ping, who was loyal to the Han Dynasty, collaborated with his uncle Dong Cheng and others to plot to kill Cao Cao. He planned to poison Cao Cao while delivering medicine, but accidentally revealed the secret. Cao Cao ordered his men to beat Ji Ping severely, forcing him to recruit someone to instruct him. Ji Ping was bleeding all over the steps, but he still scolded the traitor Cao, and then bumped into the steps and died. In Luo Guanzhong's writings, he is a famous loyal minister.

In the late Qing Dynasty, after the failure of the Reform Movement of 1898, Kang Youwei and Liang Qichao fled to Japan. Tan Sitong "had the intention to kill the thief, but was unable to save his life". He firmly believed that "if there is no traveler, there is no plan for the future; if there is no dead, there is no reward for the Holy Lord." He went to death calmly, leaving behind the famous line "I will smile to the sky from the side of my sword, leaving my liver and gallbladder intact."
