Interesting Facts about Newton
1. On September 3, 1658, there was a big storm in Newton’s hometown of Holzep Village, and people hid in their houses and did not dare to come out. The strong wind rattled the shed door, and Newton's mother told him to quickly lock the shed door. But half an hour later, my mother still didn't see Newton coming back. She felt very uneasy, so she went out to look for him. At the door, she saw that the door had been blown to the ground by the wind, while her son Newton walked along the wind for a while and came back against the wind for a while. She felt very strange and was afraid that her child would freeze, so she walked up to Newton and shouted loudly: "What's wrong with you? You're still playing outside in the cold!" After hearing what her mother said, Newton said a little aggrievedly: "Mom, where am I? Play, I am calculating the difference in speed between downwind and headwind
2. Newton was working in the laboratory. His family brought the meal to the laboratory and told him not to forget to put the two on the plate. The eggs were cooked. After a few hours, the family came to clear away the dishes. Seeing Newton still immersed in the experiment, they asked softly: "Are the eggs cooked?" Newton said without looking up: "They are cooking. !” When the family members opened the lid and took a look, they were shocked to see that what was boiling in the pot was not an egg, but Newton’s gold watch. It turned out that Newton, who was concentrating on the experiment, mistook the gold watch for an egg and threw it into the pot.
3. When Newton was a child, his family was very poor. Newton's father died because he had no money for medical treatment. It's just him and his mother living together. When Newton was fourteen years old, because his family could not afford the tuition, Newton had to drop out of school. Once, Newton's mother asked Newton to ride up the mountain to do some work. Newton was thinking about a math problem. When he figured out the problem, the horse behind him had already run away.
Interesting Facts about Edison
Edison has been curious about many things since he was a child, and he likes to experiment with himself until he understands the truth. When he grew up, he devoted himself to research and invention based on his interests in this area. He established a laboratory in New Jersey and invented more than two thousand things in his lifetime, including the electric light, the telegraph, the phonograph, the movie player, the magnetic separator, the crusher, and so on. Edison's strong research spirit enabled him to make significant contributions to improving human life style.
(1) Edison started his first experiment in his wooden shed
Since he was a child, Edison liked to use his distinctive big head to think about a series of problems. When he saw the blacksmith burning iron in a raging fire and then hammering it into various tools, he shook his big head and asked one question after another: What is fire? Why does fire burn? Why is the fire so hot? Why does iron turn red after being burned in a fire? Why does iron become soft when it becomes red? Back home, little Edison began his first experiment in his woodshed. He brought hay and lit it, trying to figure out what fire was. However, little Edison's first experiment caused a fire and burned down the wooden shed at home.
(2) "Life is too short, you have to think of more ways to do more things with less time."
"Waste, the biggest waste is to waste time. ” Edison often said to his assistant. "Life is too short, you have to think of more ways to do more things with less time."
One day, Edison was working in the laboratory, and he handed his assistant a pear without a lamp holder. He looked down at the empty glass bulb and said, "Measure the capacity of the bulb." He lowered his head to work again.
After a long time, he asked: "What's the capacity?" He didn't hear the answer. He turned around and saw the assistant holding a soft ruler to measure the circumference and slope of the light bulb, and took the measured number. He leaned over the table and calculated. Since the bulb is pear-shaped, this is not the rule. Therefore, it is very difficult to calculate the circumference and slope of a light bulb. He said: "Time, time, why does it take so much time?" Edison came over, picked up the empty light bulb, filled it with water, handed it to the assistant, and said: "Pour the water inside into the measuring cup, immediately Tell me its capacity."
The assistant immediately read the number.
Edison said: "This is such an easy measurement method. It is accurate and saves time. How could you not think of it? If you still calculate it, wouldn't it be a waste of time?"
The assistant blushed.
Edison murmured: "Life is too short, too short. Save time and do more things!"
(3) Everyone here knows everyone Me
Edison was a poor worker before he became famous. Once, his old friend met him on the street and said with concern: "This coat on you is worn out. You should get a new one."
"It will come in handy." No one knows me in New York?" Edison replied nonchalantly.
A few years later, Edison became a great inventor.
One day, Edison met that friend again on the streets of New York. "Oh," the friend exclaimed, "Why are you still wearing this shabby coat? This time, you have to get a new one anyway!"
"Is it useful?" Everyone here already knows me." Edison still replied nonchalantly.
(4) Mom, I want to create a night sun
One snowy night, Edison’s mother suddenly fell ill, and his father hurriedly called for a doctor. The doctor said: "Your mother has acute appendicitis and needs surgery." At that time, there were only oil lamps and no electric lamps. The light of the oil lamp was very dim, and you would accidentally perform the wrong surgery. Edison suddenly thought of a good idea. He took out all the oil lamps in the house and put a mirror behind the oil lamps, so that the doctor could complete the operation smoothly. The doctor said: "My child, you saved your mother with your wisdom and cleverness." Edison took his mother's hand and said: "Mom, I want to make a sun at night."
Reference: Once, Edison's mother got appendicitis. Since his family was poor, his mother asked the doctor to perform the surgery at home. The doctor agreed, but the light in the room was too dark for the doctor to see clearly. Edison had an idea. He gathered the light through the reflection of the mirror, the room immediately lit up, and his mother was saved!
(5) Even while sleeping, he was absorbing the nutrients in the book
In order to conduct experiments, Edison often did not leave the laboratory or sleep for several days in a row. I was really tired, so I took a nap on the experimental table using a book as a pillow. One day, his friend joked about him: "No wonder Edison knew so many inventions. It turned out that he was absorbing the nutrients in the book even while sleeping."
(6) Why can hens hatch babies? Chicken, I can't do that
Once, when it was time to eat, Edison still didn't come back. My parents were very anxious and looked around. It wasn't until the evening that they found him in the hay shed next to the yard. When his father saw him lying motionless in the haystack with many eggs, he asked very strangely: "What are you doing?" Little Edison replied calmly: "I am hatching chicks!" It turned out that, When he saw a hen hatching chicks, he thought it was strange and wanted to try it himself. At that time, his father pulled him up in an angry and funny manner and told him that humans cannot hatch chicks. On the way home, he asked in confusion, "Why can hens hatch chicks, but I can't?"
(7) What is the mystery in the wild honeycomb
Because Edison was interested in many things, he often encountered danger. Once, when he went to the house where wheat was stored, he accidentally fell into the wheat store. The wheat buried his head and he could not move. He almost died, but fortunately someone found him in time and grabbed Edison's feet and pulled him out. Another time, he fell into the water and was pulled out like a drowned rat. He himself was quite frightened. When he was 4 years old, he wanted to see what was hidden in a wild bee's nest on the fence, so he poked it with a branch. His face was so red and swollen that he could hardly open his eyes after being stung by a wild bee.
Interesting Facts about Einstein
Red Roses and White Roses
In the summer of 1913, two respected and authoritative scholars over fifty years old came to Zurich from Berlin. One of these two scholars is Planck, the genius founder of quantum theory; the other is Nernst, a political scholar.
What are these two great scholars doing in Zurich? go sightseeing? travel? No, they came to visit Einstein with a German mission. At this time, Einstein had a vague worry about his creativity. He once said to his close friends in Zurich, "The gentlemen in Berlin regard me as a raised egg-laying chicken, but even I don't know if I can still lay eggs!"
"The day you were born Earth, your true motherland is waiting for you!" Planck persuaded Einstein with what he considered to be the most sacred emotion. "But, I am a pacifist." Einstein said, "Will Germany really welcome me?" "Germany welcomes physicists, the founders of the theory of relativity..." "But", Einstein interrupted They said with a smile, "What does this mean? The theory of relativity is nothing. Langevin said that there are only 12 people in the world who understand the theory of relativity." "We agree with this. However, among these 12 people, Eight of them are in Berlin!" Planck and Nernst laughed proudly.
"Let's do this." Einstein's humor showed up again when faced with difficult problems. "You two gentlemen will go and play for a few days. When you return to Zurich, I will pick you up at the station. "Planck and Nernst were completely confused. "If I hold a bouquet of white roses in my hand, it means 'not going to Berlin'; if I hold a bouquet of red roses, it means 'go to Berlin'." Einstein made a romantic decision.
When Planck and Nernst returned to Zurich train station from the suburbs with uneasiness, a bouquet of red roses bloomed in Einstein's hands, and they felt relieved.
Facing waves of admirers
From the morning of November 9, 1919, Einstein became the "hunt" of the press and the public. It made Einstein extremely nervous. Einstein said with emotion: "My most ferocious enemy is the postman; I can no longer escape his enslavement!"
As soon as the morning mail arrives every day, the siege begins. He would receive hundreds of letters asking for photos and autographs. Many of the envelopes didn't even have an address, just the words "Albert Einstein." There are also letters discussing scientific issues and requests for help.
The clever Einstein came up with a way to deal with letters: ask charity organizations to collect photos and signed letters on their behalf. Anyone who donates money will get a signed photo of Professor Einstein. This really kills three birds with one stone: it not only satisfies the vanity of celebrity worshipers, but also helps the poor and saves one's own time.
Fun facts about Hawking
Although Hawking's physical disability is getting more and more serious, Hawking strives to live like an ordinary person and accomplish everything he can do. He's even lively - it's funny how, after he was completely immobile, he still insisted on using his only moving finger to drive the wheelchair on the way to the office; when he met with Prince Charles When he was riding, he rotated his wheelchair to show off, but he accidentally ran over Prince Charles's toe and was scolded by Prince Charles. From "Stephen Hawking"
There are other models to explain Cygnus X-1 that do not include black holes, but they are too far-fetched. Black holes appear to be the only reasonable explanation for this observation. Nonetheless, I made a bet with Kip Thorne of Caltech that Cygnus X-1 does not actually contain a black hole. To me, this is an insurance policy. I have done a lot of research on black holes recently. If black holes really don't exist, all my efforts will be wasted but I will be compensated by winning my bet, which will give me four years of "Private Eyes" magazine (UK) black humor magazine), Kip would only get Penthouse (an adult magazine as famous as Playboy) for one year, because But when I made this bet in 1975, we were already 80 percent sure that Cygnus had a black hole. Now I can say that we are 95% sure, but the gambling debt has been settled.

Interesting Nobel Facts
How can you know that a blessing in disguise is a blessing in disguise? ——
Fortunately, Nobel's little head is still full of ambition. Even if he takes twenty days off a month, he can still rely on his own self-study and get results that others cannot. Teachers and classmates at the school were full of praise for Nobel's performance that he spent less time studying than others but had better learning ability than others. They all praised him for his sensitive thinking and extraordinary intelligence. On the contrary, Xiao Nuo's mother often looked sad. She was worried that Nobel's academic performance would one day be compared with others. So, she asked the school teacher again and again for help, hoping that the teacher could allocate some extra time to strengthen Nobel's homework.
Of course the teacher was also happy to do this, but Xiaonuo’s homework was already good enough, and there was really no need to do anything more, so the teacher comforted her and said: “Nobel’s strength has always been ahead of the others. There are many classmates, so you can rest assured. Besides, he is already weak and sick. If we still arrange for him to receive after-school tutoring, I'm afraid it will be even more difficult for him. Let him get more rest! Everything will be easy to handle." The teacher's words did make some sense, and Xiaonuo's mother stopped worrying after hearing this.
A stone from another mountain can be used to attack jade——
Because Xiao Nuo often did not attend school, the distance between him and his classmates was never close. However, Nobel, who loves tranquility, does not feel lonely and pitiful, and never complains that he has no playmates. He is used to being alone and prefers to be alone. He often goes for a walk alone in the grassland some distance away from home. Sometimes he looks up to watch the changes in the clouds in the sky. Sometimes he bends down to touch the green grass that droops in the water. Sometimes he can even play with small stones that are lifeless. Half a day. Perhaps because of the lack of friends, Nobel had to learn to regard the things around him as his good friends, whether they are flowers, plants and trees that can be seen or touched, or things that cannot be seen or touched and can only be felt with the heart. Emotions, such as happiness, pain, etc., Nobel regards them as good partners who live together and live together. Therefore, Nobel knows how to cherish every experience in life better than other children; of course, the knowledge and understanding he gained from life are richer and deeper than other children.
At the age of ten, Lao Nuo moved his family to Leningrad, Russia, where he ran a factory manufacturing military machinery.
After living in Leningrad for half a year, Xiao Nuo's body is getting healthier day by day, and his mood is much more cheerful. So Nobel began to like to hang out in crowded places, especially his father's factory.
As long as he saw the machine turning non-stop, Nuo Xiao felt an indescribable pleasure in his heart. He felt that it was a magical thing for the machine to move. Therefore, he read books on chemistry, mechanics, and physics whenever he had free time, hoping to learn more about the principles of machine operation.
One day, Xiao Nuo discovered something exciting and fun in the factory, which was gunpowder used to load mines. When the workers were not paying attention, Xiao Nuo secretly put the gunpowder into the Niu Xiaohe -
He took it home in a leather paper bag; when it got dark, he poured the gunpowder into a cylindrical paper tube inside, erected on the grass, and then set on fire. In an instant, the sparks from the gunpowder shot straight into the sky, decorating the night sky beautifully. "Fire trees and silver flowers never leave the sky -" Xiao Nuo was very happy in his heart
Looking at the flashing sparks in the sky, Nuo Xiao was not satisfied. He thought to himself: "If you put gunpowder into an iron can, It must be more powerful." So, the next night, Xiao Nuo conducted an amazing experiment according to his own idea. He sealed the iron mouth tightly, lit the fuse, and then ran away quickly, waiting to see the good show. After a while, the iron ditch burst, and a loud bang was heard, as if the sky was falling, and the neighbors were scared to death. Later, Lao Nuo knew that it was Nuo Xiao's fault, and strictly prohibited him from playing with gunpowder again.
In order to avoid being scolded by his father, Xiao Nuo stopped stealing gunpowder powder from his father's factory and decided to make his own gunpowder.
In the days that followed, Xiao Nuo immersed himself in reading books, checking information, and doing experiments every day. It was not until the age of thirty that he finally invented the nitroglycerin detonator and obtained the patent for nitroglycerin explosive.
