The whirlpool of bath water and the distribution of earthworms

There is a famous proverb: "Truth is born after 100 question marks." This maxim is also truth in itself.

Throughout the history of scientific and technological development for thousands of years, the discoverers and founders of theorems, laws and theories are almost all very good at seeing problems from tiny and commonplace natural phenomena, seeking the source, and finally putting "?" Straighten into "!" , found the truth.

For example, taking a bath is a very common thing. After taking a shower and unplugging the plug of the bathtub, the water is washed away ... However, Professor Xie Piluo, head of the department of mechanical engineering Department of MIT, keenly noticed that every time the bath water is put in, the vortex of the water always turns left, that is, counterclockwise!

Why is this? Xie Piluo gripped the question mark. He designed a vessel for holding water. Whenever the plug at the bottom of the plate is pulled out, the water in the plate always forms a counterclockwise vortex. This proves that it is not accidental but a regular phenomenon that the whirlpool turns left when the bath water is put in.

1962, Xie Piluo published a paper that this vortex is related to the rotation of the earth. If the earth stopped spinning and unplugged the bathtub, there would be no whirlpool. Because the earth has been rotating from west to east, while the United States is in the northern hemisphere, the bath water rotates counterclockwise.

Xie Piluo believes that typhoons in the northern hemisphere rotate counterclockwise, which is the same as the whirlpool of bath water. He asserted that in the southern hemisphere, on the contrary, the bath water will form a clockwise vortex; At the equator, there will be no vortex!

After the publication of Xie Piluo's paper, it aroused great interest of scientists all over the world and carried out experiments in various places. It turns out that Xie Piluo's assertion is completely correct.

Professor Xie Piluo linked the whirlpool of bath water with the rotation of the earth and the direction of typhoon, and made logical reasoning, which is the embodiment of his keen vision and good thinking.

Coincidentally. Nearly a hundred years ago, a biologist named Michelson investigated the distribution of earthworms on the earth. He pointed out that there is a positive earthworm on the east coast of the United States and a positive earthworm on the west coast of Europe at the same latitude, but there is no such earthworm on the west coast of the United States. Michelson couldn't answer why.

Michelson's paper attracted the attention of German geologist Wei Gena. At that time, Wei Gena was studying the origin of continents and oceans. He believes that this tiny earthworm has limited mobility and cannot cross the ocean. Its distribution shows that the European continent and the American continent were originally connected, and later split into two continents. He wrote the geographical distribution of earthworms as one of the examples in his masterpiece The Origin of the Continent and the Ocean.

Wei Gena inferred the formation of continents and oceans from the distribution of earthworms, indicating that his success lies in seeking truth from question marks.

Inspiring proverbs

The whirlpool of bath water and the distribution of earthworms are very common things. Those who are good at "asking questions in the casserole" have discovered something and invented something from it. Science is not mysterious, science is not far away, and the truth is always around you, depending on whether you have a pair of keen eyes and a thinking brain.

What is the ultimate reason for asking questions?

The world-famous Honda Motor Company of Japan once used the creative thinking method of asking questions to find out the ultimate cause of the problem, thus fundamentally solving the problem.

One day, one of Toyota's spare parts production machines suddenly stopped in the production process. The manager immediately called everyone together and asked a series of questions to solve the problem.

Q: Why doesn't the machine work?

Because the fuse is blown.

Q: Why did the fuse break?

A: The current is too high because of overload.

Q: Why is it overloaded?

Answer: Because the bearing is dry, the lubrication is not enough.

Q: Why is the bearing not lubricated enough?

Answer: Because the oil pump can't suck lubricating oil.

Q: Why can't the oil pump suck oil?

Answer: Because the oil well pump has been seriously worn.

Q: Why is the oil pump badly worn?

Answer: Because the oil pump is not equipped with a filter, iron filings are mixed in.

Among the above questions, "why" is mainly used to ask questions, and six "why" are used in succession, so that the problem is fundamentally solved.

Among these questions, if you stop asking after the first "why" is solved, you think that the problem has been solved and the fuse has been installed. In this way, the fuse will blow out soon, because the problem has not been fundamentally solved.

Inspiring proverbs

When solving a problem, we should ask a few more questions and get to the bottom of it, so as to fundamentally solve the problem and eliminate possible hidden dangers as much as possible.

Why is the sea blue?

Successful people often like to think, often ask "why" and care about other people's problems very much.

192 1 year, Indian scientist Raman gave a research report on acoustics and optics at the Royal Society of England and returned home by boat via the Mediterranean Sea. Among the people walking on the deck, a conversation between an Indian mother and son caught Raman's attention.

"Mom, what's the name of this sea?"

"Mediterranean!"

"Why is it called the Mediterranean?"

"Because it is sandwiched between Eurasia and Africa."

"Then why is it blue?"

The young mother was speechless. Her eyes for help happened to meet Raman, who was listening to their conversation with great interest. Raman told the boy, "The sea is blue because it reflects the color of the sky."

Before that, almost everyone agreed with this explanation. It comes from the British physicist Lord Rayleigh, a great scientist who is famous for discovering inert gases. He once explained the color of the sky with the theory that sunlight is scattered by atmospheric molecules. It can be inferred that the blue of the sea reflects the color of the sky.

But I don't know why, after bidding farewell to mother and son, Raman has been thinking about his explanation. Curious children, big eyes for knowledge, and the constant "why" made Raman feel deeply guilty. As a well-trained scientist, he found himself unconsciously losing the boy's curiosity to pursue the unknown in all the "known", which was a shock!

After Raman returned to Calcutta, he immediately set out to study why the sea water is blue. He found that the experimental evidence explained by Rayleigh was insufficient and unconvincing, and he was determined to study it again.

Starting with the interaction between light scattering and water molecules, he obtained sufficient data of light scattering through clear water, ice cubes and other substances by using the fluctuation theory of Einstein and others, and proved that the mechanism of light scattering by water molecules makes seawater blue is exactly the same as that of atmospheric molecules scattering sunlight to make the sky blue. Furthermore, a ubiquitous light scattering effect, collectively called "Raman effect", was found in solids, liquids and gases, which provided strong evidence for the scientific community to finally accept the particle theory of light at the beginning of the 20th century.

1930, the boy's question mark on the Mediterranean boat led Raman to the podium of the Nobel Prize in Physics, becoming the first scientist in the history of India and Asia to win this honor.

Inspiring proverbs

There are opportunities everywhere in life. If you listen carefully to other people's questions, think deeply and study until you get satisfactory answers, you may get impressive results.

A combination lock on the prison door

Once upon a time, there was a king who always depended on his prime minister for everything. But then he gradually began to doubt the prime minister. I thought, "Is he too powerful and will he remain loyal to the royal family in the future?" In order to test him, the king put him under house arrest in a very comfortable dungeon with a coded lock on the door. The king said to the prime minister, "If you can let yourself out, you will be reinstated."

The Prime Minister checked the password lock and calculated that there are 280,000 possible password combinations. He also calculated that if he worked eight hours a day at the rate of trying the code every minute, he would be free after 600 days at the latest.

The Prime Minister made an accurate plan to try to crack the code. He hung up his calendar and worked wholeheartedly for 599 days. At noon on the last day, he put down the rest of the code and ate the lunch sent by the jailer.

After supper, he continued to work happily. At 4: 59, only the last password remained untouched. He smiled confidently and then dialed the last signal.

However, the lock was not opened. He knocked on the lock and it was firmly locked. The Prime Minister leaned helplessly against the heavy door, but it slowly opened. He carefully examined the prison door, only to find that when he was locked in, the king ordered not to bolt the door, and the lock had no password at all. If the Prime Minister knew this, he could get out of prison on the first day.

Inspiring proverbs

When encountering problems, don't be intimidated by superficial difficulties, calm down and try the simplest method.

Rock climbing girl

What you have is always limited, but you can create infinite miracles with limited conditions. Can you believe it? Listening to this story may be of great benefit.

The story is about a rock climbing girl who likes to challenge her own limits and the limits of nature.

On this day, she climbed a cliff as high as 30 meters alone.

She untied the rope tied to her waist and prepared to put it away for use when she went down. Carelessly, the rope slipped off the cliff.

She hurried to catch it, but it was too late. The rope fell to the ground in the blink of an eye.

She was sweating with anxiety.

Can I only die here today? Just then, she saw a shepherd boy in the distance, and she quickly called for help.

The shepherd boy came running. He looked up and shook his head in confusion.

The cliff is too high to be rescued! The girl is at a loss. Can she only be trapped today? Suddenly, she had a brainwave. She shouted to the shepherd boy, "Don't worry, I have an idea!" " "

She cut off a strand of hair and tied it together one by one, forming a string dozens of meters long and hanging down from the cliff.

The shepherd boy cut the rope on the ground into wisps and tied it to his hair.

The girl pulled the rope up the cliff with a gentle force.

After that, the shepherd boy tied a thick rope to the lower end of the rope.

In this way, at last, the girl finally pulled up the thick rope.

She fixed this thick rope on the cliff, and along the rope, the girl slipped down from the cliff and was out of danger.

Inspiring proverbs

You should make full use of all the conditions you have-even fragile hair can create unexpected miracles for you! When you are desperate, when you are desperate, you might as well open your heart and ask for help from yourself. There will always be a way out.

Because you have too much education.

An American auto mechanic has the habit of telling jokes. Once, he looked up from under the hood and asked a doctor, "doctor, a deaf and dumb man came to a hardware store to buy nails." He put two fingers on the counter and knocked several times with his other hand. The clerk brought him a hammer. He shook his head and pointed to the two fingers that had been hit. The clerk brought him nails, and he chose the right one and left. Then, doctor, listen carefully, and then a blind man came in. He wants to buy scissors. Guess what he said? "

The doctor raised his right hand and made several cuts with his forefinger and middle finger.

The repairman smiled happily after seeing it: "Ah! You idiot. Of course he said with his mouth that he would buy scissors. " Then, he proudly said, "I tested all my customers with this question today."

"Are there many people fooled?" The doctor asked anxiously.

"A lot." The mechanic said, "But I knew in advance that you would be fooled."

"Then why?" The doctor asked in surprise.

"Because you have received too much education, doctor, you can know from this that you are not very clever."

Inspiring proverbs

Franklin said, "Knowledge is not equal to cleverness. Diligent thinking is the only way to avoid foolish knowledge. Don't trust your IQ too much. "

Correct thinking is an important condition for pursuing success.

Einstein's success should first be attributed to his correct thinking and creativity.

Once, the great inventor Edison said to Einstein with great resentment, "There are many young people who come to see me every day, but none of them are worthy of me."

"What are your criteria for judging whether an applicant is qualified or unqualified?" Einstein asked.

Edison handed Einstein a piece of paper full of questions and said, "Whoever can answer these questions is qualified to be my assistant."

"How many miles is it from new york to Chicago?" Einstein looked at a question and replied, "This requires looking up the railway guide." "What is stainless steel made of?" After reading the second question, Einstein replied, "It is necessary to look through the handbook of metallography."

"What did you say, doctor?" Edison interrupted Einstein and asked.

"It seems that I don't have to wait for your refusal," Einstein said humorously, "so I declare myself unsuccessful!"

Starting from his own personal experience, Einstein emphasized not to memorize many things, but to be able to think flexibly.

Einstein believes that correct thinking is a crucial condition for pursuing opportunities.

Einstein never saw any genius when he was a child. By the time he was three years old, he could not speak. He went to school at the age of six and got poor grades in school. He was criticized as soon as he started class, and the teacher also said that he would never achieve anything. Everyone thinks he is a born fool.

However, at the age of 12, Einstein had decided to devote himself to solving the mystery of "the vast universe". /kloc-at the age of 0/5, he failed in history, geography and Chinese, and was expelled from school because of his rude attitude that undermined order and discipline.

Einstein attached great importance to thinking and imagination. He said: "Imagination is more important than knowledge. Because knowledge is limited, and imagination contains everything in the world, it promotes progress and is the source of knowledge evolution. " /kloc-at the age of 0/6, he likes daydreaming, imagining himself riding a beam of light and traveling in space, and then thinking: if there is a clock at the starting point, how can its time pass from where I sit?

From then on, he began his scientific investigation. He designed a large number of ideal experiments and put forward models such as "light quantum", which laid the foundation for the establishment of relativity and quantum theory.

Inspiring proverbs

Flexible thinking is very necessary for a person's success. With the idea that "raising a question is often more important than solving a problem", we can constantly raise questions while solving these problems and gradually reach the peak of life.

Overcome obstacles in life

There is a river flowing down from a distant mountain, passing through many villages and forests, and finally it comes to a desert. It thought, "I have crossed many obstacles, and this time I should be able to cross this desert!" " "When it decided to cross the desert, it found that its river gradually disappeared in the sediment. It tried again and again without success, so it lost confidence: "Maybe this is my destiny, and I will never reach the legendary vast sea." It talks to itself in dismay.

At this time, a deep voice came from around: "If the breeze can cross the desert, so can the river." This is the sound from the desert.

The little river replied unconvinced, "that's because the breeze can fly over the desert, but I can't."

"Because you stick to your original appearance, you will never cross this desert. You must let the breeze take you across the desert to your destination. As long as you are willing to give up yourself now and let yourself evaporate into the breeze. " The desert said this in its deep voice.

Xiaohe never knew that there was such a thing, "Give up me now and disappear in the breeze?" Don't! Don't! "The river can't accept this concept. After all, it has never had such an experience. Tell it to give up the way it is, isn't it self-destructive? "How do I know this is true? "Asked the river.

"The breeze can contain water vapor and then float across the desert. When it reaches the right place, it releases water vapor and becomes rain. Then the rain will form a river and move on. " The desert answered patiently.

"Then am I still the original river?" Xiaohe asked.

"It can be said that it is, or it can be said that it is not." The desert replied. "Whether you are a river or an invisible steam, your inner nature has never changed? You will insist that you are a river because you never know your inner nature. "

At this time, in the heart of the river, I vaguely remember that before I became a river, it seemed that I was brought to a mountainside in the inland by a breeze, and then turned into rain, which became today's river. So the river finally got up the courage, threw itself into the open arms of the breeze, disappeared in the breeze, and let the breeze take it back to the home of life (at a certain stage).

Our life course is often like a river. If you want to cross the obstacles in life, achieve a certain degree of breakthrough and move towards the ideal goal, you also need the wisdom and courage to "put down yourself (persist)" and move towards unknown areas. When the environment cannot be changed, try to change yourself.

Inspiring proverbs

In order to achieve our goals, sometimes we have to be flexible and conform to the trend, so as to find a way to survive. It is very important for a person's development to learn to change his thinking and flexibly cross the obstacles in life.

To hell with the rules

The commander tirelessly taught the pilots to fly in formation with enthusiasm and fullness. He repeatedly stressed that no matter what happens during the flight, you should keep the queue, and resolutely obey the captain's orders has become an instinct during the flight, and there is no choice.

Once, Hand heard a young pilot ask the commander, "What should I do if the pilot hits a cliff?" The commander thought for a moment and immediately replied, "I'd rather see four holes lined up on the edge of the cliff."

This is the principle. This incident taught Hand and the young pilot a vivid lesson. The commander's words, coupled with strict formation training again and again, were deeply engraved in Hand's mind.

In a flight, Hand and his companions lined up in a straight column, and he ranked third. In-line requires that the distance between the second plane and the right wing of the pilot plane is less than 6 feet, and the distance between the left wing of the third plane and the right wing of the second plane is also 6 feet.

They flew back to the base in the snowstorm, but they kept a beautiful formation at a speed of 500 miles per hour, although the airflow was very disturbing. Just as Hand was absorbed in the flight, the pilot caught a glimpse of the black hole between the clouds below and began to land quickly. He was sure that there would be worse weather, so he called the command center to cancel the original flight plan.

The original flight follows IFR rules (that is, the flight center directs the flight through radar monitoring). Canceling Joe R means turning to visual flight, and the flight center will no longer monitor it. Once IFR is cancelled, the flight is completely controlled by the pilot himself.

Their pilot is a fairly confident commander, and he will definitely break through the clouds and land safely. He must be quite surprised when he found that the hole in the cloud is actually a "black hole", because it means worse weather will follow. At that moment, as a pilot, I always think of an old saying: leave it to fate!

They tried to fly in formation. However, without any instructions, I was a little dizzy, just like in the bartender. When they rushed into the thick clouds, Hand couldn't see the other two planes. His vision was extremely limited and he was surrounded by a vast area. However, their distance is always the same. As pilots, they should ensure accurate flight at all costs.

The plane flashed in hand's sight, and then he saw the pilot and the second plane. The canopy was about six feet apart. In such an emergency, even if two planes don't collide, they will lose the most precious opportunity.

Hand decided to break away from convention and do things in his own way: "To hell with the rules." He pulled up the plane, lit the reburning device and parachuted quickly. He has decided that everything should pay attention to the right time and place, and it is time to put the formation behind him at this moment.

Hand didn't talk to the pilot, but he was sure he would be surprised at the other side of the black hole. The weather is terrible. About an hour and a half later, Hand met the pilot in the officers' club. Halfway through a bottle of wine, they all escaped an air crash. Although they have all undergone strict formation training. They are all three in one: talent (highly skilled and quick-thinking pilots), knowledge (endless flight training) and experience (coping with death).

In times of crisis, their talent and survival instinct make them walk out of the line of death and avoid falling victim to queuing flights and multi-million-dollar planes.

Inspiring proverbs

Any individual, when the crisis comes, should think of breaking the rules. In fact, many miracles in the world are the result of not following the "routine".

Escape from the clutches of the fire

In autumn, the prairie in South America seems to be a golden ocean, which is a good place to play.

On this day, a group of tourists happily chase and play on this endless prairie, singing carols for the vastness, magnificence and vitality of nature.

Suddenly disaster arrival-a fire suddenly appeared behind him, and the wind roared, cheering for the fire and heading straight for the passengers! It seems that a python is breathing fire with its 1000 mouth.

These passengers have never seen such a violent scene. They are running around in panic. However, the increasingly fierce fire came more fiercely and quickly. It seems that no matter how you run, you can't escape from the clutches of fire.

At this thrilling moment of death, an old hunter appeared in front of the tourists: "Ladies and gentlemen, stop running. Everyone still listened to me and began to pull out this hay and clear a piece of land. "

Seeing that he is an old hunter, tourists think he is experienced and immediately obey his orders. Too many cooks start to work hard and soon clear up a large piece of land.

Fire comes from the north. The old hunter asked everyone to stand at the southern end of the clearing, ran to the northern end of the clearing and moved the haystack to the north. He silently looked at the approaching fire, as if calmly treating the beast that was about to hit the muzzle.

Some tourists asked in panic: "Old hunter, what should I do if the fire burns again?"

"Don't worry, I have my own way." After a while, when the fire approached, the old hunter took a bunch of very dry grass and lit it. The grass piled up in the north of the tourists immediately burned violently, even burning against the wind in the direction of the fire. There is a fire in these two places. The fire is actually getting smaller and smaller, leaving more and more space for tourists. The two fires fought for a while and finally "exhausted" and slowly went out.

Only a big yellow-brown smoke column is left, still hovering and rising on the grass.

When the rescued passengers asked the old hunter about the mystery of "putting out the fire with fire", the old hunter took a deep breath and said, "The air above the fire will become lighter and rise after being heated, and the cold air in all aspects will be supplemented. In this way, near the boundary of the fire, there must be an airflow flowing against the flame. When the fire in our north is close to our haystack, after I light the haystack, the fire on our side will spread in the opposite direction of the wind, and there will be no grass behind the two fires, which will gradually go out. Of course, the fire can't be lit too early or too late. " The tourists suddenly realized.

Inspiring proverbs

Almost everyone knows that "fire and water are incompatible"; Only an open-minded person can think of putting out a fire with fire.

The way rich people test their sons.

Two sons are old and one rich man is old.

These days, the rich man has been thinking hard about which son should inherit the inheritance. The millionaire is puzzled.

Thinking of his self-made youth, he suddenly had a brainwave and found a good way to test them.

He locked his house, took his two sons to a city one hundred miles away, and then gave them a difficult problem. Whoever answers well will inherit the inheritance.

He gave each of them a bunch of keys and a fast horse to see who would open the door first.

The horse ran so fast that the two brothers came home almost at the same time.

But in the face of the locked door, both of them are worried.

My brother tried left and right, but he couldn't find the most suitable key from that big bunch. My brother, on the other hand, suffers from not having a key, because he just finished shopping and doesn't know when he left it on the road.

The two men were sweating with anxiety.

Suddenly, my brother patted his forehead and had an idea. He found a stone and smashed the lock in a moment. He went in smoothly.

The right of inheritance naturally fell to the younger brother.

Inspiring proverbs

There is often no key at the door of life. At the critical moment of fate, what people need most is not the key to rut, but the stone to crush obstacles!

Local regulations of Ile city

In Ile, Denmark, many people keep dogs, which affects health, hinders traffic and causes many disputes and accidents. There are more dogs, and this situation is getting more and more serious. Some people who don't have dogs will inevitably suffer when they see others have dogs, so they also have dogs.

The municipal authorities are very worried about this situation, but according to the law, there is no prohibition on keeping dogs. What should I do?

At that time, private cars had not yet developed, and most people took buses to the streets, so dog owners took their dogs with them by bus. The municipal authorities have found a breakthrough in banning dogs from riding.

So the municipal government announced a local rule: dogs and people should not ride together, but should be separated. If dogs ride alone, they should also buy tickets, which are priced according to the number of dogs. If you ride with your master, the dog is your carry-on luggage. This separates the dog from its owner.

In fact, the laws of the Danish government stipulate that you can't take your luggage on the train, and there is no special place to put your luggage. Although the local regulations of Elo City do not say that dogs can't take the bus, in fact, dogs can't take the bus.

Dogs can't ride, which is very inconvenient for dog owners. They visit relatives and friends, go to the park and go for a walk in the square. If they don't take their dogs, they will have a bad time. If you walk, people are tired and dogs are tired; It's not safe at home. It's better not to have a dog than to go to so much trouble. So fewer people have dogs.

The local laws and regulations in Elo seem absurd, even allowing dogs to use modern transportation facilities alone, but keeping dogs as a nuisance is absurd, so they use "absurd" laws and regulations to control it. This is called "fighting poison with poison", which makes the dog owner laugh and cry.

What is even more ridiculous is that the state stipulates that buses are not allowed to carry luggage, while local regulations regard dogs as "luggage". This rule is indeed specious. Dogs are not people, but things people carry with them. If not "luggage", what is it? The Ile municipal government achieved the goal of banning dogs with this specious law.

Inspiring proverbs

Everyone must act according to the law. But you can use your brain flexibly and "create" the "rules" that are beneficial to you.

Zhang Xun skillfully uses grass people

In the mid-Tang Dynasty, An Lushan launched a rebellion. The rebels were on a roll, and that day they came to Qiu Yong. Zhang Xun, a famous general, led Qiu Yong soldiers and civilians to actively resist. The guard battle lasted for more than 40 days, and all the arrows in the city were used up. Zhang Xun asked the soldiers to tie up more than 1000 scarecrows, dress them in black and tie them with ropes. At night, let the soldiers slowly put the scarecrow down from the wall with a rope. The rebels who besieged the city thought it was Tang Jun sneaking out of the city, and a burst of arrows shot away. When the scarecrow is full of arrows, the soldiers will pull the scarecrow into the city again. This process was repeated many times and thousands of arrows were obtained.

Only when the secret leaked out did the rebels know that Zhang Xun had used the trick of borrowing an arrow from the scarecrow. Another night, I saw it again.
