Newton is a world-famous scientist. Newton loved animals when he was a child. Once, his friend gave him a dog and a cat. Newton was very happy to receive the gift and took good care of his new friend. In order to facilitate dogs and cats to enter and leave the room, Newton dug two holes by the door, one large and one small. Someone asked him why you dug two holes. Newton replied, "Can a dog go through a cat hole?"
Newton's childhood was unfortunate. His father died three months before he was born. At the age of two, my mother remarried to a neighboring village. Newton had to live with his grandmother. He never spends money recklessly. His only hobby is making small crafts, saving pocket money, buying tools such as saws and hammers, and hiding in the house after school.
Newton was very attentive when he studied. Once I boiled an egg, thinking about the mathematical formula in my heart, I mistakenly threw my watch into the pot as an egg. Another time, I started working on a problem in the morning and forgot to have lunch. When he felt hungry, it was dusk. He walked out of the study, and a breeze made him feel unusually fresh. It suddenly occurred to me: am I not eating? How to walk into the courtyard! So he immediately turned around and went into the study again. When he saw the draft spread out on the table, he forgot to eat, and immediately he was nervously prone on the table to calculate.
Second, the story of Edison
Edison is a world-famous inventor. When I was a child, because my family was poor, I only went to school for three months, and I started selling newspapers at the age of eleven or twelve. He loves science and often saves money to buy science books, newspapers and chemicals. The instruments he used in the experiment were bottles and jars picked out of the garbage.
When Edison 12 years old, he sold newspapers on the train. There is a special compartment on the train for passengers to smoke, and the conductor agrees that he will occupy a corner there. He moved chemicals and bottles and cans there. After selling newspapers, he did all kinds of interesting experiments.
Once, a bottle of white phosphorus was knocked down by a sudden vibration while the train was running. Phosphorus burns as soon as it comes into contact with air. Many people came to put out the fire with Edison. The conductor was so angry that he threw all Edison's experiments out and slapped him hard that he was deaf in one ear. Edison's determination to study science never wavered. He scrimped and saved, and started his chemical experiment again. On one occasion, sulfuric acid burned his clothes; On another occasion, nitric acid almost blinded his eyes. Undaunted by the danger, he still stubbornly did the experiment.
Edison did many experiments to find a filament with low price and long life. He often works in the laboratory for dozens of hours, so tired that he lies on the experimental platform and sleeps for a while. He made unremitting efforts and finally found a suitable filament and invented the electric light. Later, Edison invented movies and phonographs ... he had 65438+ inventions in his life.
Third, the story of Madame Curie.
Madame Curie was a French-born Polish scientist who studied radioactivity and won the Nobel Prize twice in her life. Mary has been studying very hard since she was a child. She has a strong interest in learning and special hobbies. She never misses any learning opportunities easily, and shows tenacious enterprising spirit everywhere. Since primary school, she has been the first in every subject. 15 years old, graduated from high school with a gold medal. Her father studied physics at St. Petersburg University earlier, and her father's thirst for scientific knowledge and strong enterprising spirit also deeply influenced little Mary. She likes all kinds of instruments in her father's laboratory since she was a child. When she grew up, she read many books on natural science, which filled her with fantasies. She is eager to explore the scientific world. But her family at that time did not allow her to go to college. /kloc-started to be a tutor for a long time at the age of 0/9, and at the same time taught himself various courses to prepare for future study. In this way, until the age of 24, she finally came to study at the Faculty of Science of Paris University. With a strong thirst for knowledge, she listened carefully to every class. Hard work has made her worse and worse, but her academic performance has always been among the best, which not only envied her classmates, but also surprised her professors. Two years after entering school, she confidently took the Bachelor of Physics exam, ranking first among 30 candidates. The next year, she won a bachelor's degree in mathematics with the second place.
Fourth, the story of Darwin.
When Darwin was young, he once went to the garden with his mother to cultivate young trees. His mother said, "Soil is a treasure, and young trees can only grow with soil. Don't underestimate this soil, because it grows grass, fattens cattle and sheep, and gives us milk to drink and meat to eat; It grows wheat and cotton, so we can have food and clothes. The soil is so precious. "
Darwin asked, "Mom, can that soil grow puppies?"
"I can't!" Mother smiled and said, "The puppy was born by a dog mother, not a native."
Darwin asked again, "I was born to my mother, and my mother was born to my grandmother, right?"
"Yes! All the people were born to his mother. "
"Who gave birth to the earliest mother?"
"It's God!"
"Then who was born of God?"
Mom can't answer. She said to Darwin, "children, there are many things in the world that are mysteries to us." Please grow up like a small tree. These mysteries are waiting for you to solve! " "
Darwin liked flowers, trees, birds, insects and fish since he was a child. After school, he still maintains a keen interest in nature. He rode horses, hunted, fished, collected minerals, caught insects, and went into the Woods to observe the habits of birds. For Darwin, the whole world is a big question mark, and there are too many things to explore and think about. He often meditates while observing, even forgetting the danger. Once, Darwin was walking in an old castle. As usual, he was lost in thought. He walked slowly and absently, suddenly stepped on the air and fell off the battlements. At this time, Darwin was very sober and his mind was still thinking.
Verb (short for verb) Joule's story
Joule, a famous British scientist, loved physics very much since he was a child. He often does some experiments about electricity and heat by himself.
One holiday, Joule and his brother traveled to the suburbs. Joule, who is clever and studious, never forgets to do his physics experiments even when he is playing. He found a lame horse, led by his brother, and quietly hid behind him. He used a volt battery to electrify the horse, trying to see how the animals reacted after being stimulated by the current. As a result, the reaction he wanted to see appeared. The horse jumped wildly after being shocked and almost kicked its younger brother.
Although the danger has appeared, it has not affected the mood of little Joule who loves to do experiments. He and his brother rowed the boat to the lake surrounded by mountains. Joule wants to see how big the echo is here. They filled the musket with gunpowder and then pulled the trigger. Who knows "bang", a long flame spouted from the muzzle and burned Joule's eyebrows, almost scaring my brother into the lake.
At this time, the sky was covered with thick clouds, lightning and thunder. Joule, who just wanted to go ashore to take shelter from the rain, found that it took a long time to hear the thunder after every lightning. What happened? Joule didn't take shelter from the rain, dragging his brother up a hill and carefully recording the time of lightning and thunder with his pocket watch. After school started, Joule almost wanted to tell the teacher all the experiments he had done and ask for advice from the teacher. The teacher smiled at Joule, who was eager to learn and curious, and patiently explained to him: "The speed and harmony of light are different. The speed of light is fast and the speed of sound is slow, so people always want to see lightning before hearing thunder, but in fact lightning and thunder happen at the same time. "
Joule suddenly realized. Since then, he has been more fascinated by learning scientific knowledge. Through continuous study and careful observation and calculation, he finally discovered the mechanical equivalence of heat and the law of conservation of energy, and became an excellent scientist.
Six, Franklin's story
One day in June, 1752, a suburb of Philadelphia, USA, was covered with dark clouds and thundered. On a wide lawn, two people, an old man and a young man, are flying kites with great interest. Suddenly, a flash of lightning cut through the clouds and drew a "Z" in the sky. Then there was a loud thunder and the rain poured down.
The old man shouted, "William, stand in the straw house over there and tighten the kite string." At this time, lightning flashed one after another, and the thunder was louder and louder. Suddenly William shouted, "Dad, look!" " "The old man looked in the direction pointed by his son, only to see that the original bare and taut hemp rope suddenly burst into anger, and those tiny fibers stood up straight. He shouted happily, "It's coming!" While telling his son to be careful, he slowly approached the copper key attached to the hemp rope with his hand. Suddenly, as if he had been pushed, he fell to the ground and was numb. Without considering the pain, he got up from the ground and connected the Leyden bottle he had brought with him to the bronze key. There is electricity in this Leyden bottle, which releases electric sparks. It turns out that the sky electricity and the earth electricity are the same! He and his son took the Leyden bottle home like a treasure.
The people who seized Sky Power were Franklin and his son William. Franklin was not only a great scientist, but also an outstanding politician and diplomat. He was one of the founders of the Declaration of Independence and the first American ambassador abroad.
After the kite experiment, Franklin wrote a paper about the similarity between lightning and electricity, expounded the essence of lightning, and put forward the idea of making lightning rods to protect buildings from lightning. The lightning rod invented by Franklin was all the rage and spread to Britain, France, Germany, Europe and America.
Seven, the story of Nobel
Nobel's father is a talented inventor who devoted himself to chemical research, especially explosives. Influenced by his father, Nobel showed a tenacious and brave character from an early age. He often goes to test explosives with his father. Years of studying explosives with his father also made his interest quickly turn to applied chemistry.
1in the summer of 862, he began to study nitroglycerin. This is a difficult journey full of danger and sacrifice. Death has always been with him. An explosion experiment exploded and the laboratory was blown up without a trace. All five assistants were killed, even his youngest brother. This amazing explosion gave Nobel's father a very heavy blow and died soon. His neighbors, out of fear, also sued Nobel to the government. Since then, the government has not allowed Nobel to conduct experiments in this city.
But Nobel is indomitable. He moved his laboratory to a boat in a suburban lake to continue his experiment. After long-term research, he finally found a substance that is very easy to cause explosion-mercury fulminate. He used mercury fulminate to make explosive detonator, which successfully solved the problem of explosive detonation. This is the invention of detonator. This is a major breakthrough on Nobel's scientific road.
Nobel made many inventions in his life and obtained 255 patents, including 129 kinds of explosives. As he lay dying, he was still obsessed with the research of new explosives.
Eight, the story of Bell
The inventor of the telephone is called Bell. He was originally Scottish and was born in 1847. He immigrated to the United States at the age of 24 and soon became an American citizen. From 65438 to 0873, he was a professor of language physiology at Boston University. On one occasion, he tried to send several messages at the same time through a telegraph line. His idea was supported by his wife Mabel Hubbard and his father-in-law. Mabel is deaf and used to be Bell's student. Her father is very rich and generously provided the necessary financial support for his son-in-law's scientific experiment.
Many of Bell's friends want him to learn telegraphy. But the inventor disagreed. The only thing he wants to do is to finish the work of transmitting human voice. He first tried to make a "harmonious telegram"-a collection of two harps composed of charged reeds connected by a wire. At the other end of the wire, each reed has a counterpart with the same frequency. Bell hung two "harps" on a magnetic film. This film is a device that imitates the human ear.
One day, thomas watson, Bell's assistant, fiddled with the clamped reed, but Bell heard the plucking sound from the wire in the next room. He wrote down the facts, which led to further experiments. During the experiment, Bell encountered many difficulties. However, he is an open-minded and studious person, so when asking for advice from others, he got the guidance and help from some famous scientists, including famous physicists Helmholtz, joseph henry and Edison.
March 1876, March 10, Bell shouted: "Mr. Watson, please come here! I have something to find you! " Watson's assistant in the lab heard the call, jumped out of the lab like crazy and ran to the dormitory where Bell shouted. He shouted all the way: "I heard Bell calling me! I hear Bell calling me! " ……
In this way, human beings had the initial telephone and opened a brand-new communication history. 1877, the first news telegram sent by telephone was sent to Boston's Le Monde, marking the adoption of the telephone by the public. 1878, Bell Telephone Company was formally established.
Nine, Einstein's story
Einstein was the greatest physicist in the 20th century. He likes to use his hands and brains since he was a child. Once in a craft class, he wanted to make a small wooden stool. As soon as the bell rang, the students scrambled to come up with their own works and gave them to this beautiful and strict female teacher. Einstein didn't take out his own work, and he was sweating with anxiety. The female teacher looked at the boy generously, believing that he could hand in a good work.
The next day, Einstein gave the female teacher a rough small bench, and one leg of the bench was nailed off. The expectant female teacher said to the class with great dissatisfaction, "Who of you has ever seen such bad shit?" The students snickered and shook their heads. The teacher took another look at Einstein and said angrily, "I don't think there will be a worse stool in the world." There was a burst of laughter in the classroom.
Einstein blushed. He walked up to the teacher and said affirmatively, "Yes, sir, there are worse stools." The classroom suddenly became quiet, and everyone looked at Einstein in doubt. He walked back to his seat, took out two rough wooden stools from under his desk, and said, "This is my first and second time to do it. The third wooden stool was just given to the teacher. Although it is not satisfactory, it is better than the first two. "
This time, everyone stopped laughing. The female teacher nodded to Einstein affectionately and thoughtfully, and the students also cast admiration and approval on him.
This short story shows us Einstein's resilience. When he was dissatisfied with his small bench, he went into production again. He made three small benches, and the last one was better than the first two. In the process of making a small bench, Einstein showed his attitude towards himself, that is, no matter what he does, he should try his best to do it well, release his energy completely, be dissatisfied with his achievements and give full play to his potential.
The story of X. watt
Watt was born in England. Because his family is poor, he has no chance to go to school. First as an apprentice in a watch shop, then as an instrument repairman at Glasgow University. Watt is clever and studious. He often takes time to listen to professors' lectures. Plus, he plays with those musical instruments all day, and he has a lot of knowledge.
1764, Glasgow University received a newcomen steam engine to be repaired, and the task was given to Watt. After Watt repaired it, I watched how hard he worked, just like an old man panting and walking with a heavy load, and felt that it should be improved. He noticed that the main problem was that the cylinder body was hot and cold with the steam every time, which wasted a lot of heat. Can you keep the temperature low and the piston work as usual? So he rented a cellar at his own expense, collected several scrapped steam engines and decided to build a new machine.
From then on, Watt fiddled with these machines all day, and after two years, he finally took on a new look. But when trying to light the fire, the tank leaked everywhere. Watt tried to wrap it in felt and tarpaulin. Months passed, but he still failed to solve the problem. Watt didn't give up. After unremitting efforts, he finally designed a condenser separated from the cylinder, which increased the thermal efficiency by three times and used only a quarter of the original coal. As soon as this key place broke through, Watt suddenly felt that the future was bright. He went to the university to ask Professor Black some theoretical questions, and the professor introduced him to Wilkin, the technician who invented the boring machine. Technicians immediately made the cylinder and piston by boring the barrel, which solved the most troublesome air leakage problem.
1784, Watt's steam engine was equipped with a crankshaft and a flywheel. The piston can be continuously driven by steam coming from both sides, and the valve does not need manual adjustment, so the world's first real steam engine was born.
