Chapter 20: Dimensionality Reduction Strike

Qin Yang looked at the question Nobel said.

It happened to be the one he asked Xiao Qingmei yesterday.

He kindly persuaded,

"I think you might as well get another one."

Xu Shijie saw that Qin Yang actually flinched, and his confidence suddenly doubled.

"It's better than this! However, the loser must not only copy it from his classmates, but also from the next class! Qin Yang, do you bet or not! ”

Qin Yang: ?

Isn't this guy brain-pumping?

And bring yourself to pit your own?

He raised his eyebrows: "Do you really want to bet?" ”

Because of the conversation between the two, the classmates almost all turned their heads to look at this side.

or whispered, or looked astonished.

Except for Tong Wan's paintings.

Tong Wanhua kept facing forward, and there was only Qin Yang in her sight.

When Xu Shijie saw this scene, he was even more annoyed,

What's so good about this Qin Yang!

It's just that yesterday I talked about "Pipa Xing".

It must have been all after reading Tong Wan's notes to tell.

If he had Tong Wan's notes, he would be able to tell them!

But Tong Wan's painting was only lent to Qin Yang!

The more he thought about it, the angrier he became,

"I bet! However, if I don't participate, it will be unfair to you, so I think it is better to bet that I will do this problem at the same time as you, and the slow person will lose! ”

Qin Yang was happy: "Isn't this okay?" ”

If he has a golden finger in the speed, who can be faster than him?

The books he has read are automatically backed up in his head, and his homework is no exception.

In other words, he only needs to copy out the process, and he doesn't need to count it at all.

Doesn't this reduce dimensionality?

And Tong Wanhua also frowned and looked at Xu Shijie.

Of course she remembered the question.

According to the teacher's usual teaching, it takes about 20 steps to solve this problem.

But after Qin Yang asked her last night, she studied the topic again.

I found this problem practical and can be solved in ten steps.

And she also sent the process to Qin Yang.

Qin Yang must have remembered it.

Now Xu Shijie wants to compete with Qin Yang for speed.

Is this still a comparison?

However, she didn't kindly remind' Xu Shijie.

After all, she could see that Xu Shijie had been targeting Qin Yang.

For the people who targeted Qin Yang, Tong Wanhua only felt disgusted!

But when Xu Shijie saw Tong Wanhua looking at him, he suddenly felt that he had been beaten with chicken blood, completely ignoring the meaning of that look.

"Qin Yang, I don't think you dare to bet, right? It's better to admit that you copied the homework early! ”

Qin Yang sneered: "Who said I didn't dare to bet?" Teacher Luo, then please be the judge,"

Robert never interrupted the absurd conversation.

In the eyes of other teachers, this may be a waste of time and a farce.

But he sees it as healthy competition.

The college entrance examination is a single-plank bridge crossed by thousands of troops.

As a student, you have to fight with the sky, the earth, and the classmates around you!

Especially after he heard what Wang Xiaowen and Zhou Heping said yesterday, he also wanted to see what surprises Qin Yang could bring him.

So as soon as he came this morning, he asked Qin Yang if he had handed in his homework.

Now that Qin Yang wants to compare with the study committee, the bet is still to copy the physics formula, of course he strongly agrees!

"Good! Then I'll be the referee! I say start, and you all start solving the problem at the same time! Robert said.

Qin Yang and Xu Shijie had no objections.

In order to prevent cheating, Robert directly copied the question to the blackboard, and Qin Yang and Xu Shijie each took out a piece of scratch paper.

"Let's go!"

At the sound of an order, Xu Shijie immediately looked at the blackboard, and kept writing the key words and numbers in the question on the scratch paper.

Most people memorize key information, then look down and copy it on the paper, and then look up to remember the new one.

But if you go low and lift it up, you will waste at least two seconds.

The more times it takes, the more it does.

Moreover, the human brain capacity is limited, and there is not much information to remember at one time, and it is easy to write mistakes.

In case a number is wrong, or the decimal point is marked with the wrong place.

The answer to the solution can be 108,000 miles away.

And like Xu Shijie, there is no need to worry at all.

Xu Shijie is full of confidence.

This method was what he learned from Tong Wan when he peeked at her paintings.

I have to say that Tong Wanhua does have unique skills in learning.

Such a good student, how can Qin Yang, that scumbag, be worthy?

Xu Shijie quickly memorized all the key information.

And it only took ten seconds!

He was able to solve the rest of the problems.

Qin Yang couldn't be faster than him!

Thinking like this, he couldn't help but look at Qin Yang with contempt.

He must still be copying key information.

No!

He may not even know what the key information is!

Xu Shijie smiled fiercely.

However, immediately after, his smile stopped at the corner of his mouth.

What's going on?

Qin Yang kept his head down and was writing.

Why didn't he look up at all?

Could it be that he has already memorized the key information?

How is this possible?!

Xu Shijie was a little panicked for a while.

But soon he calmed down again.

Qin Yang must have pretended!

He must be writing nonsense!

He can't be influenced by him.

Xu Shijie immediately bowed his head and decided to use a faster speed to win this bet beautifully!

However!

That's it!

"Teacher Luo, I'm done."

Xu Shijie shook his pen and looked up in shock.

Qin Yang, finished writing?

That's impossible!

Robert took the draft paper handed over by Qin Yang and looked at Xu Shijie: "Xu Shijie, you can hand in yours too." ”

Xu Shijie's face turned pale: "I, teacher, I haven't finished writing yet." ”

Fang Yingjun immediately sneered: "Who was there to talk big before, and said that it would be unfair to Brother Yang not to participate, it turned out to be this kind of unfairness!" ”

Qin Yang asked very kindly: "Study committee, why don't you give you another 5 seconds?" ”

Xu Shijie couldn't hold back a word for a long time.

He did this question last night.

There are more than twenty steps to write.

Also calculated.

And he's just written an explanation now.

Don't say 5 seconds.

50 seconds is not enough.

But.

How could Qin Yang be so fast?

He clenched his fists, his eyes gloomy: "Classmate Qin solved it so quickly, did he really do it right?" If he is wrong, then classmate Qin will lose. ”

Fang Yingjun suddenly shouted: "Eh, I didn't say this before, you are a debt!" ”

Xu Shijie sneered: "Classmate Fang, I know that you don't usually study much, so you don't understand." But if it's just speed, anyone can write in a second, and there's no point in betting. ”

"It's really long-winded."

Qin Yang plucked out his ears, "Teacher Luo hasn't announced the results yet, are you in such a hurry?" Know you're going to copy the formula? ”

Xu Shijie snorted coldly and did not answer.

He didn't believe that Qin Yang could be fast and accurate.

Presumably, even if he wrote it correctly, the process must have been much simplified.

And Mr. Luo's rigor in physics will definitely make mistakes!

He looked at Robert confidently, but Robert's face was full of joy.

"Qin Yang, you have solved this problem beautifully!"

Robert was full of praise,

Fang Yingjun suddenly looked at Xu Shijie proudly: "Study committee, how is it?" Now you should be convinced! ”

"It can't be!"

Xu Shijie blurted out, "This question will take at least two minutes, how can Qin Yang do it so quickly!" ”

Robert patiently explained: "You use the method I usually talk about, that will take longer." But Qin Yang is using a new method, and ten steps are enough! ”

"I always say that you should think differently and not be too rigid when you do questions. Xu Shijie, you have to learn from Qin Yang on this point. ”

Xu Shijie's face turned blue and white for a while.

Teacher Luo actually asked him to learn from that scumbag in Qin Yang in front of the whole class?

At the end of last semester, Qinyang only scored 6 points in physics!

And he got 89!

That's a full eighty-three points higher!

Want him to learn from Qin Yang?

This is simply an insult to him!

But Robert didn't care what Xu Shijie thought.

He looked at Qin Yang's process again and nodded with satisfaction,

"The process is clear, the scoring points are all written, and the answers are correct, which is very good! However, your thinking is different from your homework, insteadβ€”"

He put Qin Yang's process and Tong Wan's homework together,

"How is it the same as Tong Wan's painting?"
