Everyone should have heard of many things invented by inventors, but do you know the stories behind their inventions? The following is the inventor's story that I share with you. Everyone is welcome to read and learn.
Inventor's Story 1? Edison
Edison (1847～1931) was an American scientist and a world-famous scientist. The King of Inventions. He made more than 2,000 inventions in his lifetime and made important contributions to mankind.
Edison was not smart when he was a child, but he was good at observation, diligent in thinking, and liked to get to the bottom of things. Once When his father saw him lying motionless in the hay, he asked very strangely: "What are you doing?" Little Edison replied calmly: "I am hatching chicks!" It turned out that he saw the hen. He knew how to hatch chickens and wanted to try it himself. His father was angry and funny and told him that humans can't hatch chickens. On the way home, he kept staring at his father and asked: "Why can hens hatch chickens?" Chicken, what can I not do?" From then on, everyone said that Edison was a "idiot". Once, in order to know the secret of fire, he actually lit a fire in a neighbor's barn, causing a fire. Afterwards, he lit a fire in a neighbor's barn. , he was severely beaten by his father.
When Edison was 7 years old, he went to school. At that time, the school curriculum was very rigid and corporal punishment was also practiced. The young Edison was very dissatisfied with this. The teacher's lectures were boring and uninteresting. His interests. He didn’t learn his homework well, but he had many strange questions in his mind. His classmates said he was stupid, and the teacher also said he was an imbecile. Less than three months after studying in school, he was forced to Dropped out of school. This was the only formal education he received in his life.
Edison’s mother personally taught her child to read and write, and took the trouble to answer all kinds of questions he raised. Once, her mother bought him After reading the "Nature Reader", he was immediately fascinated by the small experiments introduced in the book. He set up a small laboratory at home, spent all his pocket money on buying experimental supplies, and did experiments whenever he had time.
When Edison was 11 years old, he worked as a newsboy on the train. After getting permission from the conductor, he set up a simple small laboratory in a corner of the luggage car. Once, the vibration of the train knocked out a bottle of yellow The phosphorus fell to the ground and caught fire. The flames licked towards the luggage pile. Edison hurriedly took off his clothes and beat them, shouting desperately: "Fight the fire!" Everyone heard the sound and rushed to put out the fire in time. The conductor was furious Angry, he slapped Edison hard in the face and threw all his experimental supplies out of the car. Edison's right ear was deafened.
Later, Edison became a night shift operator. .One morning at three or four o'clock in the morning, he returned to his residence from get off work carrying dozens of books he bought from a second-hand bookstore during the day. The policeman on patrol saw him from a distance, suspected that he was a thief, and shouted to him to stop. Unfortunately, he was deaf and couldn't hear. Edison disappeared, but he was still hurriedly walking. The police thought he was going to escape, so they hurriedly raised their guns and shot. When the whistling bullets flew past his ears, Edison stopped. The police caught up with him, and when they asked, they found out that he was deaf, and he was carrying all the weapons. It was an old book. I took a breath and said, "You are lucky. If my shooting skills were accurate, you would have lost your life in vain!"
Because Edison made great contributions to mankind. For his contribution, he was respected all over the world. In 1922, he was selected as the first among the 12 great people in the United States.
Inventor Story 2? Bell
Bell, The man who invented the telephone. He was born in England in 1847. When he was young, he and his father were engaged in teaching deaf-mute people. He once wanted to build a machine that would allow deaf-mute people to see sounds with their eyes.
In 1873, Bell, who became a professor at Boston University in the United States, began to study the multi-task telegraph, a device for transmitting many telegrams on the same line, and came up with the idea of ??using electric current to transmit human voices to distant places. It enables people who are thousands of miles apart to have a face-to-face conversation. So Bell began researching telephones.
It was June 2, 1875. Bell and his assistant Watson were testing multi-task telegraph machines in two rooms respectively. An accident inspired Bell. There was a spring on the telegraph machine in Watson's room that was stuck to the magnet. When Watson pulled the spring open, it vibrated. At the same time, Bell was surprised to find that the spring on the telegraph machine in his room vibrated and made a sound. It was the current that transmitted the vibration from one room to another.
Bell's mind suddenly opened up, and he thought: If a person speaks to an iron piece, the sound will cause the iron piece to vibrate; if an electromagnet is placed behind the iron piece, the vibration of the iron piece will inevitably occur in the electromagnet coil. Produces sometimes large and sometimes small currents. This fluctuating current is transmitted to a distant place along the wire. Wouldn't the same vibration occur on a similar device in the distance and produce the same sound? In this way, the sound will be transmitted to a distant place along the wire. Isn't this the dream telephone?
Bell and Watson made a telephone according to the new idea. During an experiment, a drop of sulfuric acid splashed on Bell's leg, causing him to shout in pain: "Mr. Watson, I need you, please come to me!" This sentence was transmitted to Watson's ear from the telephone through the wire. Here, the telephone was a success! On March 7, 1876, Bell became the patentee of the invention of the telephone.
Bell obtained 18 patents in his life and cooperated with others to obtain 12 patents. He envisioned burying telephone wires underground or suspending them in the air, and using them to connect homes, villages, and factories. In this way, direct phone calls could be made anywhere. Today, Bell's vision has long become a reality.
Inventor Story 3? Fleming
Nowadays, penicillin has been widely used in medicine. It can kill bacteria and eliminate inflammation and infection. Maybe you don’t know that penicillin was discovered by chance!
In September 1928, the British bacteriologist Fleming was working on the study of Staphylococcus aureus, which was a Bacteria that can make people sick. In order to investigate the living habits and pathogenic mechanism of this pathogen, they need to be cultured and observed. The equipment at that time was relatively simple, and the work was carried out in an old house that was hot and humid. During the experiment, the petri dishes needed to be opened many times, and the cultures in the dishes were easily contaminated. Once, Fleming opened a petri dish to observe bacteria and accidentally discovered that blue-green mold grew on the mouth of the petri dish. Next to the mold, staphylococci were dissolved and clear water droplets appeared.
Why can blue-green mold inhibit the growth of bacteria and eliminate them? Fleming clung to this "accidental" discovery and went all out to study this blue-green mold. After conducting research on mold, we finally found penicillin, the nemesis of Staphylococcus aureus, and further discovered that it also has a killing effect on some other bacteria.
In 1945, Fleming, who discovered penicillin, won the Nobel Prize in Physiology and Medicine together with the British pathologist Florey and the German chemist Chain who developed the chemical preparation of penicillin.
Inventor Story 4? Faraday
A British physicist, chemist, and a famous self-taught scientist.
Born on September 22, 1791 in Newington, Surrey, into a poor blacksmith family. Due to family poverty, he only attended elementary school for a few years and became an apprentice in a bookstore when he was 13 years old. Working in a bookstore gave him the opportunity to read many scientific books. In addition to delivering newspapers and binding, he taught himself chemistry and electricity, and conducted simple experiments to verify the contents of the book. In his spare time, he participated in the study activities of the Municipal Philosophy Society and listened to lectures on natural philosophy, thus receiving basic education in natural science. Because of his interest in scientific research and his dedication, he was appreciated by the British chemist David. In March 1813, David recommended him to the Royal Institution as a laboratory assistant. This was a turning point in Farah's life, and from then on he embarked on the path of dedicating himself to scientific research. In October of the same year, David went to the European continent for scientific investigation and lectures, and Faraday accompanied him as his secretary and assistant. It lasted for one and a half years, and I passed through France, Switzerland, Italy, Germany, Belgium, the Netherlands and other countries, and got acquainted with famous scholars such as Ampere and Guy-Lussac. Along the way, Faraday assisted David in many chemical experiments, which greatly enriched his scientific knowledge, increased his experimental talents, and laid the foundation for his subsequent independent scientific research. In May 1815, he returned to the Royal Institution to conduct chemical research under the guidance of David. He was elected a member of the Royal Society in January 1824, director of the laboratory of the Royal Institution in February 1825, and professor of chemistry at the Royal Institution from 1833 to 1862. In 1846 he was awarded the Rumford Medal and the Royal Medal. Died on August 25, 1867.
