Edison was curious about many things since he was a child, and he liked to try it himself until he understood the truth. When he grew up, he devoted himself to research and invention according to his interest in this field. He established a laboratory in New Jersey, and invented the electric light, telegraph, phonograph, film machine, magnetic mineral analyzer, crusher and so on for more than 2000 kinds of things in his life. Edison's strong research spirit made him make great contributions to the improvement of human lifestyle.
2. Boyle
Boyle was not particularly smart when he was a child, and he stuttered a little. He doesn't like lively games very much, but he is studious and likes reading and thinking quietly. Received a good education since childhood, and studied in Europe from 1639 to 1644. During this period, he read many natural science books, including the famous book Dialogue between Two World Systems by astronomer and physicist Galileo. This book left a deep impression on him. His later masterpiece The Doubtful Chemist was based on this book.
3. 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. 15 years old, graduated from high school with a gold medal.
/kloc-started to be a tutor for a long time at the age of 0/9, and taught himself various subjects at the same time. At the age of 24, she came to the Faculty of Science of Paris University to study. Two years after entering the school, she confidently took the exam for a bachelor's degree in physics, and among 30 candidates, she won the first place. The next year, she won a bachelor's degree in mathematics with the second place.
4. Watts
Watt was born in England. Because his family is poor, he has no chance to go to school. He first worked as an apprentice in a watch shop, and then as an instrument repairman at Glasgow University. 1764, Glasgow University received a newcomen steam engine to be repaired, and the task was given to Watt. After the repair, Watt was dissatisfied with the working mode of the steam engine. 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.
1784, Watt's steam engine was equipped with a crankshaft and a flywheel. The piston can be continuously driven by steam from both sides, and the valve does not need manual adjustment, so the world's first real steam engine was born.
5. Nobel Prize
Influenced by his father, Nobel often goes to do explosive experiments 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. Because of an accident, the government banned Nobel from conducting experiments in this city.
Nobel persevered and 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, 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.
1, Newton
Sir isaac newton (1643 65438+1October 4th-1727 March 3rd1), chairman of the Royal Society, a famous British physicist, is an encyclopedic "all-rounder" and author of Mathematical Principles of Natural Philosophy and Optics.
He described gravity and three laws of motion in the paper "Laws of Nature" published by 1687. These descriptions laid the scientific view of the physical world in the next three centuries and became the basis of modern engineering. By demonstrating the consistency between Kepler's law of planetary motion and his theory of gravity, he showed that the movements of ground objects and celestial bodies all follow the same natural law; It provides strong theoretical support for the sun-centered theory and promotes the scientific revolution.
Once, Newton was doing experiments in the studio, and the time for eating had passed. He had not eaten yet.
Newton's assistant thought that Newton must have forgotten to eat. He took some eggs, sent them to the studio and whispered in Newton's ear:
"Look, you haven't eaten yet. Here are some eggs, please cook them yourself. "
"Oh, thank you, please put away your eggs!" Newton continued to do experiments.
I don't know how long it took Newton to feel his stomach growling, and then he remembered that he hadn't eaten yet. He took a small stick at random. Ok, let's boil eggs to eat.
He tied the small pot to the stove and resumed the experiment until it was finished.
"Well, the eggs are going to be cooked!" Newton opened the lid and looked. Oh, what's the matter? There were no eggs in the pot, but a watch was cooked.
Is this a trick? No. Newton looked up and saw the egg on the table, but his watch on the table was gone. Ah, ah, it turns out that Newton was so absorbed in the experiment that he grabbed a handful at random and cooked the watch as an egg in a small pot.
2.edison
Thomas Alva Edison (1847, February11-1,10, 10/8) was born in Milan, Ohio. Inventors and entrepreneurs.
One day, when his mother was busy in the kitchen, Edison came running as if he had made an amazing discovery. He opened his eyes and asked, "mom, that hen in our house is really strange." It puts the egg under its ass. Why? " Mother ha ha smiled. She put down her work and said seriously to Edison, "The hen is incubating the baby! When she heats the eggs, the chickens will crawl out of them. Look at our furry chicken. It's all warm by the mother hen. " Little Edison heard this and thought it was amazing. He thought for a moment, then looked up and asked, "Can you put an egg under your ass to keep the chicken warm?" "Yes, that's it!" Mother smiled and nodded. When the meal was ready, mother suddenly found that little Edison had disappeared and could not be found anywhere. My mother was anxious and shouted her son's name. At this moment, I heard his promise coming from the warehouse. Mom thinks it's strange. In the past, Edison made a "nest" there and put many eggs in it. He squatted on it solemnly. Mom was even more surprised and asked, "What are you doing?" Edison said, "mom, don't you understand?" I am incubating chickens! "
