The strongest brain in entertainment

Chapter 413
recording room.

Zhou Yun was full of question marks, thinking that she was also a top student in science and engineering, why did she have no idea what Li Fan said?
She asked: "Mr. Li, I still don't understand, what is chaos phenomenon?"

This cannot be explained in detail, otherwise the 30-minute program would not be enough at all.

There is no chaos theory in this time and space. If Li Fan explains it in detail, he can start the course directly, so it is concise and general.

"Chaos theory is a method of both qualitative thinking and quantitative analysis. It is used to explore behaviors that cannot be explained and predicted by a single data relationship in a dynamic system, but must be explained and predicted by an overall and continuous data relationship."

In the recording hall, there were question marks, and none of them understood.

"Uh..." Li Fan hesitated for a moment, "Let me tell you a vivid example, which is the butterfly effect I mentioned earlier.

What is the butterfly effect?This is a bold assumption.

If a butterfly in the tropical rain forest of South America flaps its wings occasionally, we can boldly believe that it may cause a tornado in Texas in two weeks. "

The audience couldn't help laughing, how is it possible?What a joke!
Li Fan didn't mind. If he hadn't studied Chaos Theory and the theory hadn't been universally recognized in his previous life, then anyone who heard about the Butterfly Effect for the first time would just laugh.

normal phenomenon!

"How could a butterfly flapping its wings cause a tornado in Texas?" Zhou Yun originally wanted to ask, "Then if I sneeze, will the Enaptina volcano erupt?", but she did not say.

Li Fan explained: "The movement of the butterfly's wings causes the air system around it to change, and causes the generation of weak airflow, and the generation of weak airflow will cause corresponding changes in the air around it or other systems, thus causing a chain reaction... …finally, leading to a tornado in Texas.

This is the butterfly effect, which is an extremely important concept of chaos theory. "

There were all smiles in the audience. After listening to Li Fan's speech, everyone had only one feeling - absurd!
It's ridiculous!

Li Fan continued: "There is a folk song in the West:
A nail is lost, a shoe is broken;
Broken a shoe, broken a warhorse;
Broke a warhorse and wounded a knight;
wounded a knight and lost a battle;
Lost a battle, lost an empire.

But in our country, there are the following vocabulary: one careless move, the whole game will be lost;

These are all related to the butterfly effect. Of course, although it is exaggerated, the purpose of the exaggeration is to highlight the inner connection of everything.

......"

In the audience, in the expert advisory group, Cui Mingyuan from the Academy of Sciences couldn't help laughing, Xie Liwei couldn't help shaking his head slightly, and Mu Zi frowned suspiciously. She thought to herself: Teacher Li shouldn't be at this level?This is too exaggerated and absurd, right?
Zhou Yun said: "Mr. Li, it seems that everyone doesn't quite approve of your chaos theory and butterfly effect."

"Well, I understand, this is not something that can be explained in a few words," Li Fan smiled calmly, "Afterwards, if I have time, I may publish a book about it and explain it in detail."

Publish a book?

Zhou Yun was very surprised, and thought: Can this also be published? !By the way, why did we talk about the "mythical theme" of butterflies flapping their wings?Oh, I asked Li Fan before, what did Li Fan think about letting Li Fan take full responsibility for true knowledge, and then Li Fan said that this should conform to the butterfly effect.

Zhou Yun decided to bring the topic back again, from "Absurd Studies" to a normal topic.She said: "Mr. Li, in the face of the accusation that Teacher Zhenzhi needs you to take full responsibility for your remarks, do you have anything to say?"

"I have nothing to say!" Li Fan smiled softly.

"what?"

"Let's enter the stage of scientific topics, let's talk about food mutual restraint!"

Li Fan really has nothing to say!

A woman tripped over a stone while running, and was sent to the hospital after her ankle was injured. In the hospital, she met her husband accompanying a girl to have an abortion... which eventually led to an unjust murder.This guilt cannot be blamed on the stone.

Film critics widely criticized the phenomenon of cutouts... and eventually, a certain movie crashed at the box office.You can't rely on film critics.

The economy of a certain tourist city has declined... You can't blame the corrupt!
Even if a butterfly does cause a tornado somewhere by flapping its wings, you can't stop the butterfly from flapping its wings just because you're worried about a tornado!

Therefore, Li Fan is innocent, and true knowledge is over-examined.

The reason why Li Fan didn't talk about this matter is because Li Fan can't fight with him on this kind of matter.

However, food is incompatible, so we can have a good chat.

Zhou Yun hesitated for a while, and said: "Okay, now let's enter our topic today: whether there is food mutual restraint or not.

Now it is obvious that Teacher Li and Teacher Wang Meng think that food incompatibility does not exist. Teacher Zhenzhi and Teacher Ren Hai think that there is. What do you think, the audience?Please press the selector in your hand. The red light means believe, the green light means no, start. "

Press the selector, and the red light on the screen instantly lights up, and there are only a few green lights!
"Okay, there are 193 people in the audience, 150 people choose to believe in food, and 43 people choose not to believe it.

First of all, I would like to ask Mr. Li Fan/Wang Meng to talk about the reasons for your doubts about the fact that food is not compatible with each other. "

Li Fan made a "please" gesture to Wang Meng, and Wang Meng immediately became more nervous and excited. After all, it was the first time he was on TV, and he was still in this state that would soon be tense.

Wang Meng stuttered and said: "I'm not...not questioning, but, I think, I firmly believe that food mutual restraint does not exist!"

"why?"

"Because, that, there is no scientific basis to support food mutual restraint!"

Zhou Yun looked at Zhenzhi/Ren Hai: "What do you two think?"

Zhenzhi showed a little arrogance: "Mr. Wang, you don't understand this. Some knowledge is gained through long-term practice. Science may not be able to explain it, but it is effective.

That's the case with food. "

Li Fan looked at Wang Meng, hoping that he would fight back, but because Wang Meng was too nervous, his head was empty. After he said "um, ah" twice, he looked at Li Fan.

Li Fan: "Teacher Zhenzhi just mentioned a word, 'effective', if food mutual restraint is effective, many people must be troubled by it.

However, in ancient times, there were not many specific cases of food mutual restraints, but in modern times, there are few reports of people who were hospitalized due to food mutual restraints.

This shows that food that is in conflict with each other is not 'effective'! "

Ren Hai smiled and said: "Teacher Li, with all due respect, don't mind, we are just discussing.

Knowing that food is mutually exclusive, who would try it out?Everyone naturally avoids eating it, right? "

The audience nodded, that's the truth, who would commit suicide?

Li Fan glanced at Wang Meng who was beside him. His forehead was sweating and his eyes were empty. Li Fan knew that he was unreliable.

In private, he's pretty good at blah blah, why did he stop cooking when he was on a TV show?
Li Fandao: "Teacher Ren Hai's idea gave rise to two problems.

The first one is the generation of rumors.

How did the rumor come about?Let me give you an example.

Everyone must have eaten tomatoes, but a long time ago, tomatoes were just ornamental plants.

It originally grew in South America and is a plant in the national forest of Peru, formerly known as 'Wolf Peach'.

There is a local legend that if you eat wolf peach, you will get pimples and tumors.Therefore, although it is bright red and beautiful, no one dares to eat it.

In the 16th century, a British duke traveled to South America, brought tomatoes back to the country, and gave them to his lover Queen Elizabeth as a gift to express his love. At this time, tomatoes became "love fruit", but no one dared to eat them. Just as an ornamental plant.

In the 17th century, a French painter painted tomatoes many times, but in the end he couldn't resist the beauty of tomatoes, so he risked his life to taste tomatoes.

As a result, the news that tomatoes were edible and delicious spread throughout the world.

Think about it, everyone now knows that tomatoes are edible, but at first, the rumor that tomatoes were not edible could be deceived for thousands of years by just a few people or even a single person.

It can be seen that rumors are very easy to generate, and the cost is 'low', and the effect is long-lasting!

Am I right? "

The audience said:

"Correct!"

"Makes sense!"

"A lot of low-level rumors are generated like this, right?"

……

Li Fan continued: "Tomatoes are not edible, they will cause pimples and tumors. This rumor was also a folk practice before the painter ate the tomatoes, right?
Teacher Ren Hai said just now, knowing that food is incompatible, who would dare to defy the law.From this, I came to a conclusion that the so-called folk experience of food mutual restraint is just the experience of individual people!
There are very few cases where people get sick due to food mutual restraint.Individual cases are not enough to replace the whole. The truth needs certain data support!
Data proves that the folk experience of food conflict can only be the folk experience of individual people.

Do you have any questions about this? "

Zhenzhi frowned: "There are also some reports of food poisoning."

Li Fan said: "There are indeed such news, but the hospital must be able to give the exact reason, the food is not washed, physical reasons, eating too much... I don't think there is any regular large hospital saying that it is caused by food intoxication, right?

Did Teacher Zhenzhi only read the title but not the content, or did he not believe the hospital's diagnosis? "

Truth: "..."

Li Fan: "What is the second question that arises from the idea of ​​Mr. Ren Hai?

Teacher Ren Hai said that whoever knows that food is incompatible will defy the law, right?
Next, we reason in reverse.I will do a survey first, on the scene, please raise your hand if you can name more than 10 kinds of food that are compatible with each other! "

Few spectators raised their hands, and spoke out the combinations of food that they knew in turn, and another spectator stood up, and reluctantly only named 8 groups of food.

Li Fan said: "Everyone has also seen that for most people, they only know that food is compatible with each other, but there are very few audiences who can name more than ten kinds of what is compatible with each other.

In the book "The Encyclopedia of Food Combinations and Restraints", there are more than 1000 kinds of foods that are compatible with each other.

That is to say, there are countless fools among us. Basically, many of us keep committing the problem of mutual restraint of food. However, aren’t we living well?
In other words, huge data prove that in our lives, we do not actually live according to the experience of food mutual restraint, but we live well.

In fact, we have been trying our best!You can read this 300-page book "The Encyclopedia of Food Combinations". "

When Li Fan lifted the book in his hand, the audience's heated discussions erupted:

"After listening to Li Fan's words, I'm suddenly enlightened! Most of us only know about the fact that food is incompatible, but not many people know about it in detail, right?"

"We've been eating casually for so many years, and there's nothing wrong with it!"

"I think Li Fan's criticism of the mutual restraint of things is quite reasonable!"

"Well, it is obviously unreasonable to use the experience of individual people to guide the lives of all people."

Another foreigner said: "There is no food in our country!"

Zhenzhi was a little panicked, and he said urgently: "We need to talk about a practical example. Eating crabs and persimmons together does cause stomach pains. This is absolutely true."

Li Fan said: "First of all, eating one kind alone may also hurt; second, whether you eat too much; third, some people's constitution is not suitable for eating; fourth, the food is not clean; fifth, the crab is not cooked enough... …I would say that there are many causes of diarrhea.

We can't say that flowers can kill people just because someone is allergic to pollen, because flowers are innocent! "

Amidst the audience's laughter, Zhou Yun said: "Everyone, please press the selector again, and we will conduct the second round of support survey!"

Swish!
On the big screen, red lights and green lights appear alternately, and the numbers are basically equal.

Zhenzhi secretly thought: I can’t seem to defeat him.
