The mystery of the daughter country
The Journey to the West described the story of the Tang Priest and his party going west to learn the scriptures and passing through the daughter country. I don't believe it will really happen. If there is, how to copy it? Genocide, it no longer exists.
Here, the name "daughter country" is used to illustrate that chemical elements do have an impact on childbearing.
There used to be a village in a mountainous area of Guangdong. A few years ago, the birth of girls in succession made people anxious. At this rate, won't this area become a girl country? Some people ask God to worship Buddha, but to no avail. An old feng said, "the geological team was looking for ore in the back mountain and it was destroyed." This is the retribution of bad feng shui! " So superstitious villagers tried their best to find the geological team that had been prospecting here and clamored for them to pay for "Feng Shui". The geological team went back to this hut, made an in-depth investigation and finally found the reason. It turned out that during prospecting, the drilling rig led out the underground spring water containing beryllium, which made the beryllium pollution spread and greatly increased the beryllium content of drinking water. Drinking this water for a long time leads to the birth of women rather than men. After governance, the situation has improved, and a boy was born in the "daughter country".
The Napoleon Murder Mystery
Napoleon, a famous French strategist, commanded thousands of troops on the battlefield before his death, and made outstanding achievements. The so-called storm was temporary, but the cause of his death has always been a historical mystery.
For nearly a century, public opinion around the world has different opinions on Napoleon's death. At that time, the French official death report determined that he died of gastric ulcer, while some people thought that he died of political murder, and some even thought that he was murdered by his rival in love in sexual matters.
In recent years, British scientists and historians have collected Napoleon's hair by means of modern science and technology, and analyzed its composition and content. At the same time, they also conducted a field survey on St. Helena where Napoleon was exiled after the defeat of the Battle of Waterloo, and obtained the wallpaper of Napoleon's imprisoned room. After research, British scientists published an analysis report and announced that the "murderer" who killed Napoleon was arsenic. The scientific name of arsenic trioxide is arsenic trioxide, which is a highly toxic substance and can enter the human body through air, water and food. Napoleon didn't eat arsenic before he died, and no one murdered him with arsenic (because eating arsenic would immediately kill him, and Napoleon died in prison). Therefore, when British scientists announced this conclusion, people were very surprised.
So how did arsenic poison Napoleon?
It turned out that in the room where Napoleon was imprisoned, wallpaper containing arsenic was stuck on the walls around him. In a dark and humid environment, wallpaper will produce a gas containing high concentration of arsenic, which will pollute the air in this room and accumulate over time, eventually causing Napoleon to die of chronic arsenic poisoning. When examining Napoleon's hair, the British Institute of Forensic Medicine found that the arsenic content in his hair was 13 times higher than that of normal people. According to the records of the prison guards that year, "Napoleon lost his hair at the last stage of his life, his teeth showed his gums, his face was pale, his feet were swollen, and his heart beat violently." This symptom is completely similar to arsenic poisoning. So the conclusion that Napoleon died of arsenic poisoning is easy to understand.
"laughing gas"
Everyone's life is full of laughter, and laughter is dominated by emotions. But there is such an anger that I can't help laughing when I smell it. Can you believe it?
At a chemistry party, performer Xiao Zhang walked onto the stage and said to the audience, "I can make the guests sitting here laugh today." Then he made several funny moves, which caused a burst of laughter from the audience. He then asked, "Did everyone laugh? Who didn't laugh? " A spectator raised his hand to show that he didn't laugh. Xiao Zhang invited the audience to the stage and asked him, "Are you sure you don't laugh?" The audience nodded confidently. So Xiao Zhang made a lot of wisecracks, and the audience remained indifferent. Xiao Zhang seems to have no choice but to shake his head. After a while, he took out a glass bottle from his pocket and said to the audience, "smell what's in this bottle." Seeing that there seems to be nothing in the bottle, the audience boldly opened the cork and sucked the bottle mouth under the nose several times. Wow! Miracle appeared, and the audience began to burst into laughter, which attracted the audience under the stage to laugh curiously with him. After everyone laughed, Xiao Zhang revealed the mystery to everyone. It turns out that Xiao Zhang collected a colorless gas in the bottle in advance, and its scientific name is nitrous oxide (N2O). Because this gas can make people laugh, people often call it "nitrous oxide" The audience didn't know there was fraud, and they burst into laughter. Of course, they have to laugh. So who first discovered this kind of laughter?
/kloc-one day in 0/800, British chemist David made a gas in the laboratory. In order to find out some physical properties of this gas, he smelled it close to the bottle mouth and laughed, which confused another colleague present. At this time, David also let his colleagues smell it, and the man smiled, so David found "laughing gas."
1844 One day, a self-proclaimed "Chemical Magic Wood Master" made an advertisement with laughing gas: "There will be a performance of inhaling laughing gas in the city hall at 9: 00 tomorrow morning. I prepared some laughing gas for the public, which can be used by 20 volunteers. At the same time, I will send eight big men to keep order, just in case something happens. I hope the public can watch it enthusiastically and gain freshness and spirit through laughter.
After this unique advertisement was posted, it really catered to the psychology of countless curiosity hunters. People rushed to buy tickets to watch the lively performance, and 20 volunteers took the stage on the spot. When they sucked people's laughter, everyone laughed, and some even sang loudly, danced and made all kinds of strange moves. The audience laughed when they saw them, and the hall was in chaos. At that time, a young man not only laughed and shouted, but also jumped up and down involuntarily, regardless of the obstruction of eight big men, jumping down from the high platform. As a result, his thigh was broken, but the young man didn't feel pain and smiled.
At this time, a young dentist came at the meeting. When he saw the painless scene of the injured person, he immediately thought that this kind of laughing gas could not only make people laugh, but also have the effect of anesthesia. Why else doesn't the young man feel pain when his leg is broken? If I use this nitrous oxide as an anesthetic for tooth extraction, I am sure I can achieve the same effect. Later, dentists also used nitrous oxide for anesthesia when pulling out dental caries, and sure enough, dental patients did not feel pain. But the dosage should be controlled well, otherwise the patient will laugh wildly and the operation will be difficult.
Since then, the role of nitrous oxide has created a new development situation in the field of anesthesiology history.
The death of the first flying man
18 in the early 1980 s, hot air balloons just appeared in Europe, and people still didn't believe in this kind of aircraft. At that time, people had successfully sent chickens, ducks and sheep into the sky with hot air balloons, but no one had left the ground with balloons. 1789, the king of France approved the plan of scientists to send people to heaven by balloon for the first time, and decided to take risks with two prisoners who had committed the death penalty.
It was known by a young man named rosier. He thinks that it is a great honor for a person to fly to heaven for the first time, and honor cannot be given to prisoners. It decided to fly, so it found another young man to show his determination to the king, and the king approved their request. So on June1783165438+1October 2 1 day, they took a hot air balloon and successfully made the world's first hot air balloon flight. The * * * flight lasted 23 minutes and the journey was 8.85 kilometers. Rauziere became a news figure at that time.
The next year, Rozier planned to fly across the English Channel by balloon. At that time, the hydrogen balloon had been invented, and he could not decide whether to take a hot air balloon or a hydrogen balloon. Finally, Rozier decided to take both balloons, that is, to combine a hydrogen balloon and a hot air balloon to fly across the strait.
One day, they put two balloons together and took off. However, tragedy happened shortly after take-off. Two balloons collided and exploded. Rosier drank another young man and ruined his young life. What caused this tragedy?
It turns out that there is a brazier hanging under the hot air balloon, which is used to heat the air in the balloon, but the balloon is full of hot air. However, the hydrogen balloon is filled with hydrogen. Luo did not expect that hydrogen is a flammable and explosive gas, which will explode when it touches Mars. Obviously, hot air balloons cannot be mixed with hydrogen balloons at the same time. Rozier is a young man who dares to take risks. It's a pity that he is only brave and lacks scientific mind, which leads to the tragedy of ball destruction and death.
Inside information about the president.
From 65438 to 0929, the rich Hoover finally ascended the throne of the 3rd1president of the United States. Fame is famous, and the secret of its prosperity becomes better.
The inside story of the maze was uncovered.
Hoover used to be from a poor family, and he barely made it through odd jobs when he was a student. Later, he was placed under the fence with a meager salary. At the end of the road, he came to China with a dusty face, hoping to turn back.
Old China, which was corrupt and backward, was slaughtered by foreign powers. How many foreigners made a fortune here! There is no doubt that Hoover has not lost hope, and soon he will have a chance to make a fortune. At that time, the level of gold mining was low, and gold was filtered and discarded. With his knowledge of chemistry, Hoover concluded that there was still a lot of gold in these "wastes", so he started his "waste utilization".
He hired someone to treat the ore with dilute solution of sodium cyanide. So sodium cyanide reacts with it, causing gold to dissolve in a complex. Then, he had zinc particles react with the filtrate, and the result of the displacement reaction was to extract pure gold.
Obviously, this method of alchemy was relatively advanced at that time. As a result, gold with good fineness kept flowing into Hoover's pocket and soon became a millionaire.
The inside story of the president's success is obvious. There are many admirers who praise them for their incomparable superiority, good money and more success. However, more sincere people know that Hoover ascended the presidency on the steps made of gold.
The mystery of crazy village
In 1930s, a strange thing happened in a remote rural town in Japan. The whole village 10 people went crazy one after another. These people are insane, behave abnormally, sometimes cry, sometimes laugh, and their limbs become stiff ... Their illness has brought disaster to their families, aroused people's turmoil, and alarmed the local government and relevant medical departments.
Local police stations and hospitals sent investigation teams to conduct a large number of interviews and investigations, and examined the body and blood components of these lunatics. It was found that the content of manganese ions in their bodies was much higher than that of ordinary people. It is these manganese ions that poison these people and make them crazy. Excessive manganese ions enter the human body, causing headache, dizziness, heavy limbs, inconvenient movement and memory loss at first. Further development makes people stiff, mentally abnormal, sometimes crying, sometimes laughing, crazy, showing disgusting ugliness. So where did the excessive manganese ions come from? It turns out that people in this town often throw used dry batteries into the garbage pit near the well. After a long time, the manganese dioxide in the battery gradually becomes soluble manganese bicarbonate under the action of carbon dioxide and water. These soluble manganese bicarbonate seeped into the well and polluted the well water. People drink water containing a lot of manganese ions, which leads to manganese poisoning, leading to a strange thing that 10 people go crazy in a short time.
Stones that can be used for weaving.
Stone is something we can see everywhere. It will be used to build a house; It will be used to pave the road. However, have you heard of it? Hard stones can also be used for weaving like cotton?
First, let's look at how cotton is woven. It turns out that in every snow-white tidbit, there are many tiny filaments called fibers. This kind of fiber is woven into cloth.
About 4500 years ago, ancient Egyptians and Mesopotamians began to burn glass with stones purposefully. Stone weaving can also be said to be the development of stone glass. Because stone weaving is to crush sandstone and lime, put them into a kiln, add some chemical raw materials, melt them into liquid at high temperature, and then draw them into glass fibers. Although the raw materials of glass fiber and glass are the same, because glass fiber is very thin and sometimes invisible to the naked eye, it enhances its flexibility and can be spun into cloth like snow-white silk. This kind of cloth is called glass cloth. Because it has many characteristics such as high temperature resistance, moisture resistance and corrosion resistance. Therefore, more and more cotton cloth and satin woolen cloth are replaced in electrical, chemical, aviation and construction departments.
Although the history of stone weaving is not long, it has a brilliant future. With the continuous updating of science and technology, more kinds of "stone cloth" will appear.
1890, Germany, one day, the number of people who hired carriages suddenly increased. The coachman asked his employer, "Where are you going?" The answer is puzzling: "Whatever!"
"Whatever?" There has never been a place called "whatever"! The coachman finally grasped the employer's meaning. The carriage wandered aimlessly in the street.
The employer seems to have no intention of watching the street view, so he closed his eyes and fell asleep. ...
Do those employers have no money to spend and hire a carriage to sleep?
Oh, later, people realized that this was the way it was-
At the meeting celebrating the 25th anniversary of the German Chemical Society, Kekule, a famous German chemist, described how he solved a big problem in organic chemistry:
"At that time, I lived in London and thought about the molecular structure of benzene day and night. I worked in vain for months and got nothing. One day, I went home in a carriage. Being overworked, I soon fell asleep in the rickety carriage. I had a dream that I had imagined for months that various molecular structures of benzene were flying in front of my eyes. Suddenly, one of the molecular structures became a snake, and the snake became a ring. Just then, I heard the coachman shout, "Sir, Crabbe Road is coming!" " I just woke up from a dream. That night, inspired by this dream, I finally drew an end-to-end cyclic molecular structure and solved this difficult problem in organic chemistry. "
Some listeners sitting in the audience thought that Kekule's success was all because he had a dream in the carriage. Therefore, they hired a carriage to roam the streets, and they also wanted to have a dream to pick the fruits of science easily. Although someone fell asleep in the carriage and had a dream, no one got anything from the dream. They don't understand that Kekule's success is because he devoted all his efforts to scientific research, so that even when he was dreaming, he didn't forget scientific research. Kekule's success comes not so much from the dream on the carriage as from countless sleepless nights!
