Zhang Yunfan is a surgeon, and his wife is a researcher at a research institute. The couple are both highly intelligent people, and they thought that with their genetics, their children would definitely be very smart.

When the child was young, he learned to speak and count much faster than other children, which made him and his wife very happy. However, when the child went to school, his performance was not as good as expected.

This caused a huge psychological gap between the two of them, just like a street writer who dreamed at night that someone was rewarding the leader of the alliance, but when he woke up, he found that it was ten starting coins.

Especially in mathematics, they basically failed every exam, which made the two of them extremely anxious. However, no matter whether they taught by themselves or hired a tutor, they could not stimulate their children's enthusiasm for mathematics. Every time they talked for half a day, they found that their children

I was wandering in my mind and didn't hear a thing.

After that, they tried various methods, but none of them had much effect; just when they were depressed, they saw Lu Qiujian's interview and program preview on the imperial stage, so they put their hope on it.

; I wonder if our teaching skills are not good enough, and let’s see if the teaching program produced by this Princeton PhD who cracked the Poincaré conjecture can arouse children’s interest.

At 8:30 p.m., the program "Learning Mathematics with Lu Qiujian" on the Science and Education Channel of the Imperial Television Station was about to begin; Zhang Yunfan, who went home from work with his colleagues to watch TV with his children, and Zhang Yichi, a junior high school student, sat on the sofa, "Son, this episode

You have to watch the program carefully, the speaker is one of the most powerful mathematicians in China right now."

Zhang Yichi looked listless and muttered, "Dad, I've heard of this person!"

"Oh? What did you hear about him?" Zhang Yunfan felt pleasantly surprised. If the child had heard of Lu Qiujian, he might be able to take this course!

"I heard that he is very good at basketball!" Zhang Yichi's eyes suddenly lit up when he mentioned this, "The Internet said that if he participates in this year's NBA draft, James will not be the top pick!"

"Um. The class is about to start. Let's watch TV first!" Zhang Yunfan wiped his sweat. Hey, it would be great if this kid could devote one-tenth of his interest in sports to studying.

The title flashed, and there was no image of the speaker on the TV screen like a normal lecture program, but just a blackboard. Then, with a click of the mouse, a question appeared in the middle of the blackboard.

Then Lu Qiujian's voice sounded, "As you can see, this is a multiple-choice question. It mainly tests your deductive reasoning ability! What is deductive reasoning? Deductive reasoning means that I give you some statements, and then you start from these statements.

Derive some results that are necessarily correct! Let me give you an example! I said that the first condition is that boys are taller, and the second condition is that Xiao Ming is a boy, then we can deduce that Xiao Ming is taller! This

It is a correct deductive reasoning process! Let’s look at this question..."

There are no exaggerated language movements or fancy speech methods, but for such a simple process, Lu Qiujian can express it in plain and simple language. Even children with poor mathematics foundation like Zhang Yichi can understand what he is saying.

What.

The first practice question about parallel lines ended quickly. Zhang Yunfan took advantage of the break to turn around and ask his son. "How was it? Did you understand?"

"I understand a little bit!" Zhang Yichi nodded, without the slightest hint of boredom or aversion to mathematics on his face, "He taught it better than our teacher!"

"Haha, that's for sure. I don't know how much better my math level is than your teacher. Let me tell you..." Zhang Yunfan laughed happily.

"Dad, please stop talking. The next question will begin soon!" He was ruthlessly interrupted by his son before he finished speaking.

Okay, okay. I won’t say anything. As long as you are willing to watch, I can do whatever you want! Zhang Yunfan quickly covered his mouth.

Lu Qiujian's program was not very long. Each episode used two or three examples to cover one or two knowledge points, and it only took about ten minutes to watch them all, which made them both feel like they still had something to say.

"Tsk, this program is a bit short!" Zhang Yunfan clucked his tongue and said, but he did find something different from the program. Lu Qiujian did not just tell them knowledge points in the program, but more importantly, cultivate them.

If students learn the correct way of thinking in mathematics, then learning mathematics will be a matter of getting twice the result with half the effort.

"It's not too short, it's pretty good!" Zhang Yichi's eyes sparkled, "Our teacher only teaches so much knowledge in one class, but it's not as easy for people to understand as he does!"

"As long as you like it, let's continue watching this show together tomorrow night!" Zhang Yunfan is in a good mood now. He didn't expect that a TV show would solve the problem that he had spent so much money on.

After comforting the child, I immediately called my wife who was working overtime. There was another burst of surprise and yelling, saying that she would not work overtime tomorrow and that she would go home and watch it with them no matter what!

A similar situation happened in many students' families. When Zhang Yichi arrived at school the next day, he found that many classmates were discussing yesterday's program.

The students discussed enthusiastically, and parents also called to tell their relatives and friends one after another; when the second episode of the program began, the ratings survey of Chaoting Channel showed that the ratings of "Studying Mathematics with Lu Qiu Jian" were obviously

It has increased a lot.

By the beginning of the third episode, the ratings increased again compared to the second episode. They continued to rise for more than ten years before they finally stabilized. The ratings of a small teaching program actually exceeded many old prime programs, which surprised the Imperial TV station.

, hurriedly increased Lu Qiujian's remuneration, and wondered whether to extend the duration of the program and release some DVDs or something to increase income.

Except for refusing to increase the duration of the program, Lu Qiujian simply agreed to all other conditions; whether it was to release a disc or upload the program to the official website of Chaotingdai, he did not make too many demands.

I don't want to gain much benefit from this, spreading knowledge is the most important thing.

At the same time, there is another advantage of doing this, that is, it can increase one's popularity and refresh one's reputation; Hawking's achievements in physics are not necessarily better than those of Chen Ning Yang and Witten, but his popularity is much higher than that of these two people. One of them

The important reason is the role of the popular science books "A Brief History of Time" and "The Universe in a Nutshell". (To be continued.)
