The Story of Innovative Celebrities Part I: Luban Invented the Saw
Legend has it that one year, Luban accepted the task of building a huge palace. The palace needed a lot of wood, so he and his disciples had to go up the mountain to cut wood with axes. At that time, there was no saw, and the efficiency was very low. Once he went up the mountain, he accidentally caught a handful of weeds growing on the mountain, but he cut his hand at once. Lu Ban wants to know why a grass is so sharp. So he picked a leaf and observed it carefully. He found many small teeth on both sides of the leaf. These little teeth are very sharp when he touches it gently. He knew that his hand had been cut by these small teeth. Later, Lu Ban saw a big locust eating leaves in a meadow. The two large molds are very sharp. As soon as they opened and closed, they quickly ate a big piece. This also aroused Lu Ban's curiosity. He caught a locust and carefully observed the structure of its teeth. He found that locusts also had many small teeth on their two big dies, which were used by locusts to bite grass leaves. These two things gave Lu Ban great inspiration. So he made a bamboo chip with many small serrations from a big bamboo, and then went to a small tree to do experiments. The result was really good, and soon a deep ditch was drawn on the trunk, which made Lu Ban very happy. However, bamboo can not be used for a long time because of its softness and poor strength. After pulling for a while, some small serrations are broken and some are dull, so it is necessary to replace bamboo. Lu Ban thought of iron pieces and asked the blacksmith to help him make small serrated iron pieces. Lu Ban and his apprentice each pulled one end and pulled it up on a tree. I saw them coming and going, and soon I sawed off the tree, which was quick and labor-saving, and the saw was invented.
Before Luban, many people must have been cut off by Mo Ye. Why only Luban was inspired by it and invented the saw is undoubtedly worthy of our consideration. Most people just think that this is a trivial matter in life and it is not worth making a fuss about. After the wound heals, they tend to forget it. However, Lu Ban has strong curiosity and correct ideas. He paid great attention to observing, thinking and delving into some small things in life, from which he found ways and ideas to solve problems and even obtained some creative inventions. This tells us a truth. Paying attention to many trivial things in life and thinking seriously will increase a lot of wisdom. After inventing the saw, Lu Ban invented many woodworking tools, which are recorded in ancient books.

For a long time, the ancient Greek astronomer Ptolemy? Geocentric system? Ptolemy believed that the earth was the center, and the sun, moon, planets and stars all revolved around the earth. Later, Copernicus overturned Ptolemy's theory. Copernicus expounded Heliocentrism in "On the Movement of Celestial Bodies", telling us that the sun is the center of the universe and the earth revolves around it. Then, Bruno accepted and developed Copernicus' Heliocentrism, who thought that the universe was infinite and the solar system was just a celestial body system in the infinite universe. Galileo observed the celestial bodies through a telescope and found that the spherical surface of the sun is uneven. Jupiter has four satellites, the sun has sunspots, the Milky Way is composed of countless stars, and both Venus and Mercury have profit and loss phenomena. Soon, Kepler analyzed Tycho? According to Bula's observation data, it is found that the planet runs in an elliptical orbit, and three laws of planetary motion are put forward, which laid the foundation for Newton to discover the law of universal gravitation. Therefore, it can be said that science is a process of continuous discovery and truth is a process of continuous innovation.
