Just turned over a new leaf and became a wise and intelligent student

Chapter 64 Technology is the real profit
“In fact, I think chemistry is really interesting.”

Xu Qingshan was holding the comprehensive science test paper from the biweekly exam and talking to Ye Xincheng.

"Go away, I don't want to talk to you."

Ye Xincheng was listless.

He now seriously suspected that Xu Qingshan would absorb other people's luck and expertise, and then gain progress through malicious competition.

What a hateful man!
"Why?"

"Isn't it just that your score in Chemistry is one point lower than mine?"

Xu Qingshan put down the test paper and put his arms around Ye Xincheng's neck.

"Is that a one-point thing?"

Ye Xincheng looked desperate.

"There has appeared an unbridgeable barrier between you and me, brothers."

This is a half-month exam.

With a total score of 658 and ranking 24th in the grade, Xu Qingshan once again proved that his success was not accidental, and he is still maintaining a very high upward trend.

Xu Qingshan has been thinking about learning since he returned. After discussing the key to advanced chemistry with Ye Xincheng, he finally began to find the joy of learning.

Xu Qingshan laid a solid foundation by organizing knowledge points and improved his scores by doing massive amounts of practice questions.

At that time, the so-called joy of learning was actually just the pleasure of improving the final score at the settlement stage of each exam, not the joy of learning itself.

But after going through the stage where he urgently needed to change his family and social status.

Xu Qingshan can no longer rely on simply answering questions.

Practicing basic question bank has little effect on him now.

He began to explore the fun of the subject.

It would have been fine if he hadn't dug into it, but once he did, Xu Qingshan finally understood what true enlightenment was.

Thinking driven by a combination of interest and subjective initiative is countless times more efficient than thinking purely for the sake of scoring.

"But, Shan'er, how did you manage to improve so quickly in such a short time? Even if I saw the framework and ideas you listed that day, no matter how quickly you organized them, you still needed time to understand them, right?"

Ye Xincheng was very puzzled.

He put Xu Qingshan's and his own comprehensive science papers together, and took out the papers from last monthly exam.

Although the difficulty of the comprehensive science test this biweekly was much simpler than the last time, this was not a reason for Xu Qingshan to improve his chemistry score from 80 to 99 in one go, right?

From the content of the answers on the test paper, it is actually very easy to tell whether a student’s performance is due to good on-the-spot performance or real understanding.

In Xu Qingshan's comprehensive science paper, the answers were accurate, precise, the reasons were detailed, the calculations were clear, and there were no unnecessary steps in the thinking.

It can be seen that he has thoroughly mastered high school chemistry.

"Isn't it because of my brother Cheng's good teaching? That's why I'm improving so fast."

"Please stop talking. The more you say that, the more depressed I get. I didn't even teach you my method, and you figured it out."

Ye Xincheng became even more depressed.

But no matter how depressed he was, he also wanted to know Xu Qingshan's secret.

Ye Xincheng has no utilitarian motives, he is purely passionate about chemistry.

"In fact, I just memorized too much before, and practiced basic questions to thoroughly master the breadth of knowledge."

Xu Qingshan explained.

“Now that I have constructed the core concepts, I can immediately connect all the previously isolated knowledge points together. All the knowledge is active in my mind like atoms and molecules.”

Xu Qingshan randomly picked up a homework paper and planned to share his ideas with Ye Xincheng in a more systematic way.

“The core concept is actually the elements of the periodic table that we talked about before. I understand it as three characteristics.”

"First, it is core. This occupies the core position of the knowledge network and is the key bridge to establish connections between small concepts. It is like a knowledge tree. If it is separated from the core, the isolated knowledge points will only be fallen leaves and forgotten."

“Second, abstractness is actually tracing back to its origin and summarizing the general characteristics of the entire system. It is the essential connection of knowledge.”

"Third, transferability. The core concepts explain the essence of things. The simulation experiments you mentioned can be transferred to different real situations. They can solve our academic problems and some similar and homogeneous problems in life."

What Xu Qingshan said was not actually innovative. He just summarized Ye Xincheng's method into a more systematic system.

"And we also need to distinguish between concepts and terminology. Teacher Bai Qi sometimes confuses us when he teaches."

"When teachers talk about terms like acid, amount of substance, constants of chemical equilibrium, and hydrolysis of salts, do we often treat them as concepts?"

"But if we only repeat the appearance and ignore the meaning, we will confuse the concepts, just like when we occasionally make mistakes in answering questions, we may write ionization as electrolysis and say conservation of electrons is conservation of charge. These are all normal. Sometimes the teacher does not notice and gives points for the exam, but the college entrance examination will not give points. Even if the college entrance examination gives points, will the real physical world give points? No."

Xu Qingshan fully demonstrated his system concept.

Ye Xincheng fell into deep thought.

He knew how to do it, but he lacked scientific guidance.

His knowledge of chemistry is based on years of love and study.

Ye Xincheng originally thought that the occasional problems he encountered during exams were due to carelessness.

But now it seems that may not be the case.

"When I was understanding the entire general high school chemistry system, I used complete sentences to express the chemical concepts I understood, removing professional terms and multiple concepts, and expressing them in the most authentic statements. Just like."

"All matter in the universe is made up of tiny particles."

“It’s a combination of cognitive concepts and existing experience.”

“Then I discovered that the general meaning of [particles] would lead to questions. When I discovered and raised questions, my interest, passion and innovative ability would emerge.”

"So, I build my solid academic system by understanding the core at the macro level, explaining the causes at the micro level, and expanding the lower-level concepts."

Xu Qingshan has already written a complete cognitive system on paper.

This is also how he finds fun in chemistry recently.

"If we really want to define chemistry as a discipline, I think"

“Chemistry is a basic discipline that studies the composition, structure, properties, transformation and application of matter at the atomic and molecular levels. Its characteristics are to understand matter at the microscopic level, describe matter in symbolic form and create matter at different levels.”

“It explains the research object, research content, research perspective and chemical characterization methods, as well as the value of this discipline.”

Ye Xincheng suddenly felt that Xu Qingshan had a kind of concentration and enthusiasm for understanding the origin of science.

It is just like when he was a child, he saw his grandfather taking the materials he brought home to titrate and test them, and saw the materials slowly changing color, which aroused his interest in chemical materials.

It comes from human beings' most primitive desire to explore and learn knowledge, nature, and science.

And a strong desire for control and power to take over the world.

Ye Xincheng suddenly felt that Xu Qingshan's rapid improvement in chemistry was not so exaggerated.

For example.

Xu Qingshan used to memorize chemical formulas, knowledge points, and practice question banks as if he was practicing martial arts routines.

He only has routines, which are somewhat effective against the enemy, but they are purely based on posture.

But it's different now.

He has understood and explored the essence of chemistry in high school, found the joy of learning and exploration, and built his own core knowledge system. Then he has achieved great internal success.

Xu Qingshan's strong internal strength and rich martial arts routines make him invincible in both the application of practical knowledge and in examinations.

To put it in a not very appropriate and mature way.

If Xu Qingshan wants to drop out of school now.

Then there will definitely be a top-notch technical super-fan tycoon in the Golden Triangle of Southeast Asia, and the things he produces will probably be terrifyingly pure.

Changing careers can bring disaster to the world.

Xu Qingshan just felt that he was terribly strong now.

Of course, just think about it.

He had promised to walk the right path in this life, and the future materials market is so vast, Xu Qingshan doesn't think that working in high-tech will be worse than making powder.

Technology is the real source of huge profits!
