Reborn I want everything

Chapter 18
The other party changed it to "polite request", but Gu Zhe couldn't just forcefully go back, that would make him appear unmannered.

Of course, if Gu Zhe was willing to make a move, it would be very easy to crush the opponent.

However, Gu Zhe, who was a lawyer in his previous life, believed in a creed: no referee, no debate.

Whether it is a lawyer's court debate or an academic defense in scientific research, it is only valuable if a more authoritative third party is present.

Otherwise, there are only two parties with conflicting interests, just wasting time and talking nonsense.

In his opinion, what is Feng Tao?Even the teacher who supervises the scene is nothing, and he doesn't make money if he wins.

Fortunately, the two chatted for a while, and more and more people gathered in the corridor outside the laboratory. The other candidates who came to adapt to the venue also took a break to watch the excitement.

Because the congestion in the corridor affected traffic, within a few minutes, it finally provoked the dissatisfaction of a famous professor of the Academy of Chemical Sciences passing by.

"What's the excitement in the laboratory building? Pay attention to discipline, everyone is gone!" A young square-faced professor with a fierce face couldn't help but reprimanded him.

"It's Professor Zheng Jianzheng! The academic leader in the field of polymer materials! Don't offend him. You have to hang out with him if you want to produce results in chemistry." Some candidates whispered and dispersed immediately.

The supervisor in the laboratory, seeing this, hurriedly told Feng Tao to stop making trouble, and rushed to the corridor in two or three steps to explain to the professor.

Zheng Jian didn't give him face, and directly reprimanded him: "Xiao Wu, you too, you can't manage a laboratory well, no wonder you have been teaching assistants. What's the situation?"

Teaching assistant Xiao Wu: "A few students who practiced the experiment were discussing the problem, which attracted other test-preparing students to watch. Nothing else."

Professor Zheng understood the cause and effect, and he figured it out immediately. However, he didn't like people who rely on policy dividends to make a profit, so he walked up to Gu Zhe and said:

"Then are you sure? If you don't want to practice this question, just tell me quietly, and I will let them all disperse. If you are willing, I will not let you suffer.

This kind of skill is impossible to test, but it can barely see the solidity of the basic skills of the experiment.You guys from Zhenyang Middle School have also been tricked into being good-looking. If you really behaved better, the higher-ups would be able to explain it to you. "

Gu Zhe understood immediately:

Because last year's competition was the first time that the system of "consolation prize quota for recommended students" was implemented, so some people must be dissatisfied.

On the contrary, if the beneficiaries of the reform, such as Zhang Ming, who was recommended by Zhenyang Middle School last year, performed better than the other recommended students who won the first prize in the province based on their real strength, then the reformers can Tree model, talk about him.

It's a pity that Zhang Ming's strength is indeed not comparable to the other three provincial first prizes, and he can't compete with it.

At this time, once someone notices Gu Zhe's positioning, they might look forward to his performance - if Gu Zhe performs well and has a good academic future in the future, then the reformers can also say:
"Other high schools in the province also have top-notch talents in this area. At the beginning, they were only beaten to the ground by the ugly monopoly of Ark No. [-] Middle School, which led to insufficient competition and buried talents. "There are leftovers in the wild." After the reform, these people saw hope, so they worked hard, and they really had stamina, grew up, and became 'Wild Witnesses'."

Anyway, people are in the arena, and it is impossible to quit the arena.

Gu Zhe didn't care at first, he was sure to crush Feng Tao.It's just that I don't think it's worth proving to the little guy. Now that the bosses are watching, and there are so many interests behind it, it's okay to take the opportunity to show off.

As a reborn person, Gu Zhe also knew that the later generations of Professor Zheng could be regarded as figures in the field of polymer materials in China, and after more than ten years, he was transferred to a provincial university in another province as the president.

Gu Zhe is still soft-spoken now, it's okay to sell the other party's face and make him familiar.

He glanced at Feng Tao's bag that was placed on the seat next to him and slightly opened a slit. He already had a plan in mind, and he agreed generously:

"Since Professor Zheng also thinks that this kind of practice is helpful for the understanding of basic skills, then I will try."

After Gu Zhe finished speaking, Zheng Jian gave Xiao Wu an order: "Find me in the office later and tell me the result."

Then he left. He was very busy and didn't have time to stand by and watch the students do experiments for half an hour.

The other teachers and students were finally able to watch in the corridor openly. After such a commotion, several supervisors from the nearby laboratory also came.

Gu Zhe did not panic at all.

He went through the density tables and mutual repulsion of all commonly used solutions in his mind. The density of water is 1, the octane of gasoline is 0.7, the pentane of the lightest alkanes is 0.62, and the A and B Propane is a gas at room temperature.

In fact, pentane can’t be used in summer now. It boils at 36 degrees, it’s very unstable, and it evaporates all at once.

To make a multi-layer water-oil mix, the difficulty lies in the water-based inorganic solution, which is generally denser than the solution composed of gasoline and other organic substances, so it is difficult to achieve oil on the water, water on the oil, and layers of puff pastry. distinct.

However, alcohol can be used as a medium. The ethyl group in ethanol is a lipophilic group, and the hydroxyl group is a hydrophilic group.If it is applied properly, and a series of subtle solutes are used to adjust the density of the solution, there is still a lot of room for manipulation.

This is also the underlying physical and chemical principle why alcoholic beverages can be played with so many cocktails.

Of course, the difficulty here cannot be explained clearly in a few words. A layman only needs to know that it is difficult. One carelessness can easily lead to the separation and stratification of water, oil and alcohol.

All in all, in his previous life, Gu Zhe had finished his undergraduate degree in material chemistry and had done several years of scientific research. His accumulation and depth of understanding are obviously far from comparable to Feng Tao's.

Based on his rich experience, after thinking about the operation in his heart, Gu Mo configured the operation, and then poured layers of liquid into the separating funnel along the glass rod.

The density of each layer ranges from 1.33 grams (saturated brine) to 0.7 grams (octane), almost every 0.15 grams of density difference, Gu Mo can steadily make a layer of mutually exclusive layered solutions, and finally in the separatory funnel There is a "six-layer cocktail" in it.

In order to facilitate the teacher's observation, he thoughtfully added appropriate colorants to each layer when configuring.Then, he poured six layers of water-oil spacer solutions of different colors into six beakers, and each cup was very precise without mixing other colors.

When Gu Zhe finished the final operation, several teaching assistants present were quite surprised, and some teaching assistants thought they couldn't do this.

And those students who had never seen the world opened their mouths enough to stuff a duck's egg, and they didn't dare to breathe loudly for fear of affecting Gu Mo's operation.

Even if you are a layman, counting will always count. The difference between being able to divide into six layers and dividing into four layers is still very obvious. The former must have a much better grasp of density difference and mutual solubility.

In the amazement of everyone, assistant teacher Xiao Wu was going to the office to find an opportunity to report what he had seen here.Feng Tao, on the other hand, wanted to pack his bag with a shy expression on his face.

But Gu Zhe is an old Jianghu after all, he has observed clearly a long time ago, he blocked Feng Tao's hand, and said with a sneer:
"It's a good calculation. It's a digital camera. If you win, you can record it. Maybe it will be useful in some occasions in the future. If I win, I will delete the SD card directly.

This is treating me like a rabbit and you like a tortoise.The moment the rabbit accepts the challenge, he has already lost money, and it doesn't matter if he wins. "

After all, Gu Zhe had been a lawyer for many years, and he had already noticed this little trick of secretly collecting evidence just now.

What's more, the digital camera in 02 is still so stupid, black and thick, you have to open a big slit in the bag to avoid blocking the lens.It's impossible for Feng Tao to get a spy-level miniature camera, so he won't be seen through directly.

Gu Zhe was clear in his heart: That guy just wanted to get some extra information, maybe he could go to the media to complain and criticize last year's new policy of recommendation.

As soon as Gu Zhe said this, the supervisor teacher and other students were naturally very upset. How could he do this?
Although the things in the laboratory are not personal privacy, and the protection of this aspect of the law in 02 is not clear, but their moral intuition makes them feel that this kind of filming is not authentic.

Xiao Wu's Assistant Jiaojiao negotiated sternly and asked him to hand over the SD card involved, and Feng Tao also admitted that he was wronged.Not touching his camera is already considered a protection of private property, and he is relatively restrained.

Then Xiao Wu took the card and took a few students to Professor Zheng's office, and simply gave a reward.

There are several other professors and associate professors who are engaged in chemistry in the office, and some of them happen to be drinking tea just fine, so they come to listen to anecdotes together.

Naturally, the professors would not be surprised, but nodded slightly: "It seems that there are good seedlings in the experimental operation among the freshmen this year, and we will pay more attention to it when the official exam comes."

Professor Zheng himself didn't really have anything more to ask, but after all, he asked Assistant Teacher Xiao Wu to report. Out of politeness, he asked Gu Zhe a few more questions, wanting him to talk about his experience in practicing experiments and why he was right. These useless operations are so familiar.

Gu Zhe naturally belongs to the type of person who doesn't talk too much, so he said directly:

"Maybe I like to think more and have a better grasp of the underlying principles. I actually don't like to practice those fancy operations, but I don't want to do too many things, so I can experience the pain points and solve the problem once and for all."

"Solve it once and for all?" After hearing this, Professor Zheng was really interested in Gu Zhe. He put down his pen, "How can I solve it once and for all? What can it solve?"

Gu Zhe stopped talking, took the pen that Professor Zheng had put down, and wrote two strings of numbers.

Professor Zheng was taken aback: "What is this?"

Gu Zhe put down his pen: "Several utility model acceptance numbers can help cocktail bartenders add interlayers to density-layered wines, which can be regarded as similar to the experimental operation I practiced today.

This is the value of my practice of these useless operations - smashing myself, thinking through the underlying principles, and then inventing something to simplify other people's operations. "

Professor Zheng finally stood up in awe: "You just graduated from high school, and you actually have a patent under your name? What a formidable young man."

As a professor, he has quite a few patents under his name, at least a few of them are "invention" level, much higher than Gu Zhe's "utility model".But there is a patent after high school graduation, which is undoubtedly worth paying attention to and cultivating.

In Professor Zheng's heart, the idea of ​​cherishing talents has already been born, and when Gu Zhe is admitted to Zhu Kezhen College, he must give him good advice.

Gu Zhe clarified without being humble or arrogant: "It can't be regarded as having a patent under his name. This is just an acceptance number, not an authorization number. It just means that the National Intellectual Property Bureau has started to review my content, and it hasn't been reviewed yet."

Professor Zheng nodded: "It's right for young people to be more rigorous. Well, you are a special candidate for additional examinations these days. Take the exam well. I hope you will study chemistry hard after entering Zhu Kezhen College, and do some research along the way. Achievement."

……

The familiar venue on the last day before the exam ended in this little episode.

After Gu Zhe went back to the hotel to rest, the other candidates who practiced chemistry were still telling his legend, thinking that his operation is definitely not something that a high school student who has only practiced for two years can accumulate.

Early the next morning, it was the official additional test for special admissions for chemistry.However, after the twists and turns of the previous day, when it came to the official exam day, there was nothing new to write about.

All the students who knew Gu Zhe had higher expectations of his strength, and it wouldn't be too surprising if they finally found out that he did well in the exam.

For the content of the exam, there is a written test first in the morning, and I just used the test paper of the global finals that I used in the Netherlands yesterday to save trouble, but I am not afraid of leaking the questions. First, the time is too short. Too late to prepare.

If someone has a super high score in the theoretical part but a poor test score, then it may need to be reviewed. If both are good, it doesn't matter.

Because there are not many candidates recruited for the additional chemistry test.At that time, there were only more than 200 students in Zhu Kezhen College, 60 students in each of mathematics, physics and chemistry. Before the competition recommendation and other self-enrollment recommendation, 40 places for each major had been used up.

After the college entrance examination, only 20 people will be recruited in each direction, and they will be distributed to so many provinces. Donghai Province can only retain single digits.For this kind of exam to recruit several people, it is not cost-effective to prepare a set of papers carefully.

In his previous life, Gu Zhe had repeatedly done the questions of the global finals that year, so he naturally passed the written test with ease, and even handed in the papers in advance.However, the written test part is not marked immediately, so the invigilator cannot immediately see his level.

In the experimental exam part in the afternoon, it actually showed immediate results.Gu Zhe was as fierce as a tiger in his operation, and completed the "preparation of polypeptides under the environment of amino acids with protective groups" perfectly.

The second part of the experiment is to take the peptide I just produced, analyze and verify the purity, and write an analysis report. If it is not pure enough, analyze the reason.

The second part does not mean that the more beautiful the analysis data is, the higher the score is, but the more realistic the analysis data is, the higher the score will be.But there was no way, Gu Zhe completed the first step too well, and the quality of the produced product was too high, so that there was nothing to write in the analysis report of the second stage.

So, the experimental part was handed in nearly an hour earlier than others—no way, I was so successful, you asked me to analyze the reasons for impurity and the lessons of failure, what can we write?Wouldn't it be good to have a few simple sentences and a conclusion?
At the end of the day, the teachers in charge of the exam already knew that Gu Zhe had almost a perfect score in the experimental part. With this single item alone, he was definitely recruited into Zhu Kezhen Academy.

PS: There are a lot of technical details today, and I have tried to explain them in a simple and easy-to-understand manner.Some places even sacrifice precision.Considering that some book friends don't like to read technology, I added more than 7000 words today, and passed the plot of the contestant's exam within a day.
