Recording Hall.

Zhou Yun was full of questions, thinking that she was also a top student in science and engineering, why did Li Fan say nothing of what he had at all?

She asked, "Teacher Li, I still don't understand. What is chaos phenomenon?"

This cannot be explained in detail, otherwise this program, which is only 30 minutes long, would not be enough.

There is no chaos theory in this time and space. If Li Fan explained in detail, he can directly open the course, so he summarized it briefly.

"Chaos theory is a method that combines qualitative thinking and quantitative analysis, which is used to explore the behavior that cannot be used in a dynamic system, but must be used to explain and predict the whole and continuous data relationships."

There was a question mark in the recording hall, and I didn't understand it.

"Uh..." Li Fan hesitated for a moment, "I'll tell you a vivid example, which is the butterfly effect I mentioned before.

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

A butterfly in the rainforest of South America, with occasional flapping wings, we can boldly think that it may cause a tornado in Texas, USA in two weeks.”

The audience couldn't help laughing. How could it be? What a terrible thing!

Li Fan didn't mind that if he had not learned the chaos theory and had not been recognized in his previous life, then anyone who heard about the butterfly effect for the first time would just laugh it off.

Normal phenomenon!

"Just flapping butterflies just flapping their wings, how could it cause a tornado in Texas?" Zhou Yun wanted to chase after him, "Then if I sneeze, will Mount Enaptina be erupting?", but she didn't say it.

Li Fan explained: "The movement of the butterfly wings causes the air system around it to change and cause the production of a weak airflow. The production of a weak airflow will cause corresponding changes to the air or other systems around it, which will cause a chain reaction... Finally, it leads to a tornado in Texas.

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

Everyone in the audience was smiling. After listening to Li Fan’s speech, everyone had only one feeling - absurdity!

It's really absurd!

Li Fan continued: "There is a folk song in the West:

Lost a nail and broken a hoof;

A hoof was broken and a war horse was broken;

He broke a war horse and injured a knight;

Injured a knight and lost a battle;

Lost a battle and destroyed an empire.

In our country, there are the following words: if you are not careful, you will lose everything; if you are a little different, you will lose a thousand miles; if you are a thousand miles of dike, you will lose a thousand miles of dikes...

These are all related to the butterfly effect. Of course, although it is a little exaggerated, the purpose of exaggeration is to demonstrate the inner connection between 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 but shake his head slightly, and Mu Zi frowned in confusion. She thought to herself: Teacher Li shouldn't be at this level? Is this too exaggerated and absurd?

Zhou Yun said: "Teacher Li, it seems that everyone does not agree with your chaos theory and butterfly effect."

"Well, I understand, this cannot be explained in just a few words," Li Fan smiled indifferently. "In the future, if you have time, I may publish this book for this and explain it in detail."

Publish a book?

Zhou Yun was very surprised and thought to herself: Can you publish a book? By the way, why did you talk about the "mythical topic" of butterflies flapping their wings? Oh, I asked Li Fan before, what did Li Fan think about True Knowledge and Li Fan, and then Li Fan said that this should be in line with the butterfly effect.

Zhou Yun decided to bring the topic back again and return to normal topics from "absurd learning". She said: "Then Teacher Li, in the face of Teacher Zhenzhi's reproach that you need to be fully responsible for your remarks, do you have anything to say?"

"I have nothing to say!" Li Fan chuckled.

"ah?"

"Let's enter the scientific topic stage and talk about food incompatibility!"

Li Fan really has nothing to say!

A woman tripped by Shitou while running, and was taken to the hospital after being injured in an ankle. She met her husband with a girl in the hospital... and eventually led to a murder case. The blame cannot be blamed on Shitou.

Movie critics widely criticized the phenomenon of young and handsome guys cutting pictures... In the end, the box office of a certain movie collapsed. The film critics were innocent.

The economy of a certain tourist city has declined...fǎn    Corruption is innocent!

Even if a butterfly flaps its wings, it is impossible for a butterfly to flap its wings because it is worried about a tornado!

Therefore, Li Fan is innocent and true knowledge is too much.

The reason why Li Fan did not talk about this is because Li Fan could not fight with him in such a thing, which would be a bit harmful to his face. However, food is incompatible, so we can have a good chat.

Zhou Yun hesitated for a moment and said, "Okay, let's go to our topic today: Does food inseparable or not exist?

It is obvious now that Teacher Li and Teacher Wang Meng believe that food incompatibility does not exist, Teacher Zhenzhi and Teacher Ren Hai believe that there is, what do you think about the audience? Please press the selector in your hand. The red light is to believe, the green light is to be negative, start."

When the selector is pressed, the red light on the screen instantly lit up, and there are only a few green lights!

"Okay, there are 193 spectators on the scene, 150 people chose to believe that food is incompatible, while 43 people chose not to believe.

First, please let Teacher Li Fan/Wang Meng talk about the reasons why you question the incompatibility of food."

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

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

"Why?"

"Because, that, food inseparable has no scientific basis to support it!"

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

True knowledge shows a little bit of arrogance: "Teacher Wang, you don't understand this. Some knowledge is the experience gained through long-term practice. Science may not be able to explain it, but it works.

This is how food incompatible.”

Li Fan looked at Ren Hai, hoping that he would strike back, but Ren Hai was too nervous and his head was empty. After two "Yeah," he looked at Li Fan.

Li Fan: "Teacher Zhenzhi just mentioned a word, 'It works effectively'. If food is incompatible, many people will inevitably be troubled by it.

However, in ancient times, there were not many specific cases of food inseparable, but in modern times, few reported hospitalizations due to food inseparable.

This shows that food inseparable is not 'effective'!"

Ren Hai smiled and said, "Teacher Li, I'm sorry, don't mind, we're discussing this.

Even though we know that food is incompatible, who will try the method with our body? We will naturally avoid eating it, right?"

The audience nodded, this is the reason.

Li Fan glanced at Wang Meng beside him. The man's forehead was sweating and his eyes were empty. Li Fan knew that he was unreliable.

I am quite good in private, why do I stop eating after I appear on TV?

Li Fan said: "Teacher Ren Hai's idea has given rise to two problems.

The first is the emergence of rumors.

How did rumors 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 Peruvian national forest. It was originally named "Wolf Peach".

There is a local legend that when eating wolf peaches, they will get lumps 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 and brought tomatoes back to the country. He gave them to Queen Elizabeth as a gift to express his love. At this time, the tomatoes became a "love fruit", but no one dared to eat them, just as an ornamental plant.

In the 17th century, a French painter portrayed tomatoes many times, but in the end he could not resist the beauty of the tomatoes, so he risked his life to taste the tomatoes.

So, news that tomatoes are edible and delicious spread all over the world.

Think about it, everyone knows that tomatoes can be eaten, but rumors that tomatoes are inedible can only be blinded by the words of a few people or even one person.

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

Am I right?"

The audience said one after another:

"right!"

“It makes sense!”

"This is how many low-level rumors arise, right?"

...

Li Fan continued: "Tomatoes cannot be eaten, they will make people get lumps and tumors. This rumor was also a folk practice experience before the painter ate the tomatoes, right?

Teacher Ren Hai just said that even though he knew that food was incompatible, who would try the method with his own body? From this I came to a conclusion that the so-called food was incompatible with the people was just the experience of some individuals!

There are very few cases of illness caused by food restraint. Individual cases are not enough to replace the whole, and truth requires certain data support!

Data prove that the folk experience of food restraint can only be the folk experience of individuals.

Do you have any questions about this?"

Machi frowned: "There are also reports that they were poisoned by food."

Li Fan said: "There is indeed such news, but the hospital can definitely give the exact reason, the food is not washed clean, the physical condition, and eating too much... I don't think there is a regular hospital saying that this is caused by food incompatibility?
To be continued...
