Little Inventors
Alexander bell 1847 was born in Edinburgh, Scotland on March 3rd. His father and grandfather are both famous singers. They have worked among deaf-mute people for many years and have made in-depth research on human vocal mechanism and auditory characteristics. Bell's father also created a set of "sign language" to speak with gestures and mouths, which brought great convenience to the deaf. Bell lived in such an environment, was influenced from childhood, and had a strong interest in the transmission of sound. This undoubtedly laid the groundwork for his later invention of the telephone.
But Bell is not a child prodigy. Many inventors were not smart when they were young. Their success lies in their hard work all their lives. Although Bell is an expert in acoustics, he can skillfully translate the "sign language" of deaf-mute partners, but he can't keep up with other classes. His mischievousness and playfulness are even more famous in the whole school. His schoolbag often contains small animals such as sparrows and frogs for him to dissect and play with. Once, when the teacher was talking about the Bible on the stage, the mouse caught by Bell got out of his schoolbag and ran around the classroom, which caused everyone to burst into laughter and made the teacher tremble with anger.
Bell was later transferred to London by his grandfather, and was directly instructed by the phonetic expert. This is a stubborn old man with personality. He loves his grandson very much, but he is strict. He teaches like a lion, and his gray beard often scares Bell. But Bell likes him very much, because his grandfather is so knowledgeable that he is an encyclopedia. Bell lived with him for a year and learned a lot. Bell later recalled: "My grandfather made me realize that I didn't know the general courses that every student should know. I often feel ashamed of my ignorance. He aroused my ambition to overcome ignorance. " It is this ambition that inspired Bell to embark on the road of exploring scientific truth.
Bell returned to his hometown from London, and his interests changed. While studying hard, he began to show great enthusiasm for invention and creation.
There is an old waterwheel mill near his home, which is run by a young man. Later, the young man went to the army, leaving a helpless old man to make a living by grinding flour. The grinding disc is driven by water. When the water quantity is large, the grinding disc rotates, and when the water quantity is small, the grinding disc stops rotating. It is driven by manpower. Every season when the amount of water decreases, the elderly have to close their doors and make do with their usual savings. Bell felt sorry for him and invited a group of young companions to help him. Everyone pushed and pulled. It was fun at first, but it was boring after a few days. In the end, Bell was left alone. He tried to suck milk, but it was difficult to push the stone mill.
Bell hasn't let go of the water mill since he got home. "Why can't I design a lighter water mill?" In order to design a new water mill, he went into his father's study every day, looked through all kinds of materials, buried himself in design drawings and pondered over them repeatedly. After more than a month, he actually designed the drawings to improve the waterwheel. Several craftsmen saw the plan and appreciated it very much. The picture is not beautiful, but the principle is clever. After the planned restructuring, the friction of the waterwheel is greatly reduced, and even children can push it. As soon as the news came out, the surrounding villages and towns came to imitate it. Bell was only fifteen or sixteen at this time, and at that time he became a hero in the eyes of his companions.
After Bell became a small inventor, some friends who were interested in science often revolved around him. With everyone's recommendation, Bell organized his friends, established the "Youth Science and Technology Association", and formulated the articles of association, requiring each member to take a subject, give a speech once a week, and publish his own research results. Bell taught phonetics and biological anatomy. The lecture hall is located in the attic above his father's study. This group of young scholars often participate in activities, which have increased their knowledge and made many jokes.
Once, a member found a dead pig on the side of the road, thinking that everyone usually studies frogs, beetles and the like, and it would be more interesting to experiment with pigs this time, so he dragged the dead pig to the attic. Dambert saw that the pig had won the treasure, and he began to speak in front of all the members. After talking about the physiological characteristics of pigs, Bell began to dissect. Unexpectedly, the pig died for many days and its internal organs were corrupt. Suddenly, the stench rushed out and all the members of the house ran away, covering their noses. However, Bell kept a straight face and insisted on dissecting the pig himself.
