There is no need to be too normal to be a doctor

Chapter 71 Is this a medical student?you sure?
This brief silence revealed a bit of seriousness and embarrassment.

Qin Xuehai was a little embarrassed at this time. After all... he could hear Chen Gong's voice.

However, as an important member of the research team, Zhang Nan, although not the person in charge, can definitely be ranked in the top five in terms of contribution.

The most important thing is that he is backed by the Bone Research Institute, which is an indispensable part of the project.

For a moment, Qin Xuehai looked a little embarrassed. He wanted to say something to explain, but... he didn't know what to say.

"Well, Professor Zhang... I'm sorry."

"This is my student."

Qin Xuehai still stood up to defend Chen Gong. It is normal for young people to make mistakes.

Who hasn’t come through it when they were young?

"Professor Zhang explained this very well!"

“Everyone once again gives our applause to Professor Zhang.”

Zhang Nan heard the sound and quickly stretched out his hand: "Wait!"

He looked for the voice and finally saw who was speaking from the angle.

It's just... After seeing the success, Zhang Nan's eyes suddenly changed. From the initial curiosity, he instantly turned into fanaticism!

It's him!

this kid!

Zhang Nan has been dreaming about this figure these days.

At such a young age and with a medical background, he was able to turn the Q&A room of Professor Chai Jiurang of Shanhe University upside down.

The most important thing is that the ideas put forward by the other party completely enriched his theoretical system, which was enough to support him in completing this topic, and even gave him an additional scientific research thinking in the future scientific research path.

It can be said……

Although he had never met this boy, he had been a close friend of Zhang Nan in his dreams for a long time, and even inspired and guided him a lot.

In a sense, this young man is his noble person!

Now, it seems that many doubts have been explained clearly.

No wonder he went to the Q&A room to ask a question about orthopedics, and it was about calculating the amount of cervical spine loss.

It turns out that he is also in this research group!

Moreover, the most crucial and magical thing is...

Qin Xuehai didn't even know that this boy was the genius he dreamed of!
However, at this time, Zhang Nan couldn't care less about the surprise of reunion with this young man.

At this time, after hearing Chen Gong's question, he was also a little confused.

He knew that Chen Gong was definitely not out of touch, and he definitely raised the question after careful consideration.

Being called a genius in Mr. Chai Jiurang's mouth is enough to prove how good Chen Gong's biomechanics is.

Zhang Nan clearly remembered that Chen Gong said that he had only studied mechanics for half a month!

This half month of biomechanics... made a group of university academics in the Q&A room blush.

Therefore, Zhang Nan quickly said: "Can you please repeat what you just said?"

Chen Gong heard the sound and didn't pay attention to the people around him. He nodded and looked at Zhang Nan and said:

"Professor Zhang, I didn't mean to offend you, because your thinking coincides with my previous thinking."

"That's why I asked the question just now!"

“Using the calculation of the amount of loss, combined with the mechanical vector data of the pedicle, it is indeed possible to explore and find the optimal point.”

“You choose pedicle fixation as a hypothesis quantity, and then combined with a large amount of data analysis, you can prove that the strength, stiffness, and torsion resistance of the vertebral body and intervertebral disc are good biomechanical properties.”

"However, you have overlooked a very important variable, which is the discarded x factor."

"Here, we can no longer study it with simple biomechanics and osteology."

After Zhang Nan heard Chen Gong's words, his expression suddenly changed. A trace of doubt flashed in his eyes and he looked at the blackboard again.

Chen Gong saw that Zhang Nan was in doubt, so he simply stood up and walked towards the stage.

He knew that it would be difficult to make the other party understand simply by dictating.

Seeing Chen Gong stand up, Li Jinhuan, deputy director of the Department of Orthopedics, the second person in charge of the project, was about to stand up, but was stopped by Qin Xuehai.

"and many more!"

After Chen Gong stepped onto the stage, he directly erased the entire back part of the blackboard.

Only the previous assumptions and the first few steps of calculations are retained.

Then!

Chen Gong took the chalk and started writing directly.

Chalk made a scratching sound on the blackboard.

Zhang Nan's eyes were staring straight at the content on the blackboard.

3 minutes later……

His eyes suddenly widened in disbelief.

He did not expect that Chen Gong directly inserted the x factor. If this factor was added, it would be difficult to continue the calculation.

However, Chen Gongfei did not stop and continued to discuss the x factor!
at last!

Five minutes later, Zhang Nan's hands were shaking with excitement.

Correct!
right here!

He got stuck here many times, wondering why he couldn't get through and why he couldn't accurately find the calculation amount and area.

It turns out to be right here!

What exactly is this interference factor?
At this time, Chen Gong directly drew the structural model of the lower cervical spine on the blackboard, and then began to regulate the auxiliary lines.

"Using mechanics alone cannot solve the problem!"

“Rather, it needs to be combined with complex variables and vector and tensor forms in advanced mathematics.”

"Through the study of complex variables, and then using geometric equations to accurately control the variables..."

Zhang Nan immediately looked at Chen Gong excitedly: "The variable you are talking about is..."

Chen Gong smiled: "You know the three-column stable structure, right?" Zhang Nan nodded quickly: "Yes!"

"Three-column theory. Denis created the three-column theory in 1983 based on Holdworth's two-column theory, emphasizing the role of ligaments in stabilizing the spine."

"You are saying...this complex variable is the ligament?!"

Chen Gong nodded: "That's right!"

"You see, we conduct a mechanical analysis on the three-column theory. If we add the variable factor of ligament, it will be much more accurate!"

"Although the amount of calculations will continue to increase, it will undoubtedly be much more accurate."

"Ligaments in the front, middle and back, after a fracture occurs, will be damaged. Even if it is repaired after surgery, it is still a variable."

"If this happens……"

Zhang Nan nodded excitedly at this time: "Yes!"

"You are so right!"

"This x factor is the key point in the generation of variables. If it is removed, although it can still go down, new variables will be added."

"As a result, when the results appear, they are not accurate enough!"

"But if we do more calculations and add variables, although the amount of calculations will increase proportionately, it will undoubtedly be more accurate..."

……

Most of the people in the audience have master's degrees, associate professors, professors, and chief experts.

But at this time, everyone looked at the various auxiliary lines, various calculation formulas, various variables on the blackboard...

I was a little dazed for a while.

I... where am I?
What am I doing?

Why can't I... understand?
In fact, even Qin Xuehai may not be able to understand it.

Putting aside advanced mathematics, he couldn't even figure out simple biomechanical calculations.

There are specialties in the academic field. If you discuss mathematics and mechanics in front of a group of medical experts, are you polite?
But, Chen Gong is just a student?

How old is he?

He...how could he understand?
He could even have a conversation with Zhang Nan. No, to be more precise, Zhang Nan was like a student, watching Chen Gong answer the questions, as excited as a child who had just found the answer.

It’s simply too outrageous!
Liu Yueqing and Li Bo looked at each other with disbelief in their eyes.

This...is this Xiao Chen?

Why do they feel so strange?

Those who didn’t know thought that this was an expert invited by Professor Qin from Shanhe University!

Time passed by minute by minute.

Chen Gong suddenly stopped.

He turned around and glanced at Zhang Nan: "Can you understand?"

Zhang Nan blushed: "Can...can you?!"

Chen Gong suddenly frowned: "Can you really understand?"

Zhang Nan coughed: "Basically able!"

Chen Gong was about to write when he suddenly hesitated and handed the chalk to Zhang Nan: "Then just finish writing the last few steps."

After Chen Gong finished speaking, he stood aside.

Zhang Nan stood there, stunned.

This……

Why does this scene feel so familiar to him?
Seems like I've seen it somewhere?
However, looking at the chalk in his hand.

He glanced at the announcement on the blackboard again and walked over hesitantly.

but……

Less than three steps.

Chen Gong frowned and said, "Wrong!"

"Do you really understand?"

Zhang Nan stopped pretending and said with a blush, "I don't understand very well."

"You...you are a little over the top."

"These are advanced mathematics categories, and they are operations on complex variables in advanced mathematics."

"I...I don't quite understand."

Chen Gong suddenly frowned, looked at Qin Xuehai, and then at Zhang Nan: "I heard Professor Qin say that you are not a double-degree expert from the Institute of Orthopedics?"

"Don't you need to study high mathematics?"

Zhang Nan blushed: "I have only learned the basics. After all, I only supplemented my study of mechanics in order to study orthopedics."

Chen Gong sighed helplessly:
"Hey!"

"As a doctor, especially an orthopedic surgeon, if you are engaged in research, you don't dare to learn too little."

"Besides, isn't it normal for people who do research to know advanced mathematics, biochemistry, biomechanics... and other subjects?"

“There were elective courses in college!”

After speaking, Chen Gong simply wrote out the answer.

When everyone in the audience heard Chen Gong's words, their scalps suddenly went numb!

Is it normal? !

Who says doctors must be good at math?

Who said you need to study mechanics to do research?
Who said it's normal for doctors to do this?
This is not normal, okay? !
This is not normal at all!
Even Qin Xuehai blushed and remained silent, for fear that Chen Gong would ask him to come up and do the questions.

At this time, Qin Xuehai actually felt the fear of being called on during ward rounds when he was at school!

Too scary!
