From top student in college to scientific research powerhouse

Chapter 58 Impossible! This is impossible!

"Predictive modeling of complex flow fields is a major problem in aerodynamics research. Finding an optimal balance design under the influence of multiple physical factors..."

"Look here, everyone. Each of these is a common influencing factor on air resistance and barodynamics..."

"By utilizing in-depth analysis of the computer's neural network structure with refined analytical techniques, we can calculate the threshold for each influencing factor and design a corresponding scoring system..."

On the podium, Ma Jianze began to give a serious report.

His report focused on modeling methods for 'optimal equilibrium design under the influence of multiple physical factors'.

Although it is called 'multiple physical factors', which seems to cover a very wide range, it is actually limited to the application problems encountered in aerodynamics.

This is normal.

Optimization modeling influenced by 'multiple physical factors' can be considered a complex discipline.

Each problem in this field requires specific research; there is no single framework that can be used to analyze different problems.

Ma Jianze explained the method using the example of the 'complex flow field prediction' problem.

Predictive modeling of complex flow fields is a mathematical physics problem with wide applications.

Ma Jianze is an aerodynamics expert whose research revolves around the aviation field. The physical influencing factors listed in his report are all aimed at the problem of 'aircraft engine optimization'.

Aero-engine optimization involves analyzing the relationship between blade geometry and aerodynamic pressure to optimize compressor blade design, thereby enabling real-time prediction of flow field characteristics. This process involves many interfering factors.

If an optimal mathematical model could be developed, it would reduce the difficulty of experimental corrections in blade design and manufacturing, and improve the performance of aero engines.

Ma Jianze first explained the method of building mathematical models using modular views, and then went on to talk about the details of each step.

His method is to list out all the interfering factors and then perform threshold analysis on each of them.

The next step is to score the impact threshold of each factor, and the scoring system is the core of the entire study.

Ma Jianze also focused on the scoring system.

With a scoring system in place, the thresholds defined for each influencing factor can be directly compared numerically, allowing us to arrive at the 'optimal solution' step by step.

Inside the venue, many scholars were listening attentively.

Zhang Minghao was holding a pen and scribbling in his notebook, already in a state of half-listening and half-not listening.

When Ma Jianze introduced the research method using modules, he had already discovered the problem: establishing a scoring system based on threshold analysis of influencing factors was simply impractical.

To address the problem of constructing a mathematical framework under multiple physical influencing factors, his research method involves using "Correct Perception" to analyze the 'threshold region' of each part.

The next step is to overlay them together and find the optimal framework using "Correct Perception".

The most important aspect is "correct perception," not the research methodology. Conventional methods can also find the optimal framework, but the difficulty of this cannot be solved by a scoring system that relies on mathematical computer analysis.

If the method is wrong, the final conclusion will definitely be wrong.

Zhang Minghao is comparing the influencing factor thresholds listed on the curtain wall to find a counterexample to the 'optimal framework'.

Meng Guoqing noticed that he was writing something and asked in surprise, "What are you writing?"

"Find a counterexample."

"A counterexample? You mean the optimal framework he developed is wrong?"

"Of course it's wrong."

"He hasn't finished speaking yet? How did you find out?" Meng Guoqing was very puzzled.

He frowned and continued, "Besides, finding counterexamples isn't easy, is it? If it were easy, they would have discovered the problem long ago."

"I'll try."

Zhang Minghao smiled nonchalantly.

Ma Jianze's report was very long, and he skipped some parts of it, but it still took him an hour to finish.

After the report was finished, it was time for the Q&A session, and the room remained quiet.

There was no applause, and no questions were asked.

The judges in the front row were scratching their heads, mainly because the report was too complicated.

Predictive modeling of complex fluids is inherently complex, and the 'optimal scoring system' involves computer-aided calculations, making it impossible for anyone to judge its accuracy.

"That scoring system is very interesting!"

The expert judge in the front row whispered, "Overall, there are no problems, but whether it is 'optimal' can only be verified through countless experiments."

"That's already very impressive. We can test this model, which is constructed using such a system, in an experiment..."

Although it's impossible to determine whether it's the 'best' option, the reviewers still gave it a very high rating.

The judges should immediately stand up to express their approval.

Ma Jianze also smiled.

The next moment, he stopped laughing because a young man in the back row stood up.

It was Zhang Minghao.

The scholars in the lecture hall all looked over. "I know him, Zhang Minghao, a doctoral student at Jiangzhou University, and he's in the physics department." "He's been on the news a few times. This morning he even found a problem with Zhang Hua's team's photonic chip design."

"He looks like a college student!"

Some speculated, "Could he have found something wrong with it too?"

Ma Jianze and Zhang Minghao exchanged a glance. He frowned and asked, "Zhang Minghao, what's wrong?"

Zhang Minghao exclaimed, "Professor Ma, your research is highly innovative!"

"Establishing a unified scoring system for threshold analysis of influencing factors is a groundbreaking new method, and the complex analysis involved is so incomprehensible that I even find it hard to understand..."

Ma Jianze immediately curled up the corners of his mouth.

Before he could even feel happy, he heard the next sentence, "...but the final result was wrong!"

"What did you say!"

Ma Jianze immediately questioned loudly.

Zhang Minghao said seriously, "What I mean is that the mathematical model you finally built is not optimal."

After he finished speaking, he walked down the aisle to the front of the podium, handed the notebook in his hand to Ma Jianze, and explained, "This contains a set of values ​​that cover the threshold range of all influencing factors. You can substitute them into the calculations."

“Each value is within the scope of the analysis, but the whole is outside the ‘optimal framework’.”

"In addition, this set of values ​​is higher than all combinations of values ​​in the 'optimal framework'."

To put it simply, it means that a set of numerical combinations has emerged that is outside the 'optimal framework' but is 'better' than the 'optimal framework'.

Ma Jianze simply didn't believe it. After they developed the 'optimal framework,' they conducted numerous numerical verifications but found no problems.

The other party just listened to a report and found a 'better' combination of values?
impossible!
His eyes were full of disdain, thinking that Zhang Minghao was deliberately causing trouble, but he still took the notebook and glanced at the numerical combinations on it.

One glance was enough to freeze his expression.

Having performed numerous numerical verifications, he was able to quickly determine that the numerical combinations on the notebook were indeed "better" than the "optimal framework".

"But it's definitely not within the threshold range of influencing factors!"

After thinking for a moment, Ma Jianze casually said, "Zhang Minghao, your set of values ​​is indeed better, but it should be outside the range."

"If you don't believe me, let's verify it right here."

He smiled at the scholars in the audience, showing confidence in his research: "If someone questions my research, we'll verify it."

A commotion broke out in the meeting room.

Many scholars were also curious about the results, but most were more optimistic about Ma Jianze because his research was very complex and not easy to understand.

It's not easy to understand even this, so how could we possibly find the 'optimal' counterexample in a short time?

Verification has begun.

The staff brought over a new whiteboard, and Ma Jianze substituted the values ​​one by one to perform calculations, verifying whether each value was within the threshold range of the corresponding influencing factor.

If any value is found to be outside the range, the set of values ​​is considered incorrect.

Ma Jianze's calculation speed was very fast; he completed the verification of half of the values ​​in just about five minutes.

When he couldn't find any values ​​outside the threshold after continuous calculations, the pressure on him increased, sweat appeared on his forehead, and his calculation speed slowed down considerably.

After completing the calculation of the second-to-last value, he went back to review the verification process of the first value.

He was clearly panicked. "Impossible, this can't be!"

"How can they all be within the threshold range? Every single value is within it? That's impossible..."

The scholars in the conference hall also noticed the problem.

If every value is within the threshold range, it means that the value group is valid. However, if the value group is "better" than the "optimal framework", it means that the derived framework is not "optimal".

To further clarify, Ma Jianze's research is wrong!
As more people realized the problem, the room erupted in noise. "The verification really isn't the problem?"

"So, the research was wrong? And that complex evaluation system was wrong too?"

"Why isn't it the last one?"

Ma Jianze stood motionless on the stage, seemingly not intending to perform the final numerical verification.

Some scholars, growing impatient, simply started calculating themselves. The calculations, which involved substituting numerical values, were easy, and some quickly arrived at their results.

"The last value is also fine!"

"I've calculated it too, and the value does indeed fall within the threshold range, which means this set of data is correct."

"Is Ma Jianze's research wrong?"

"That's definitely wrong! If a better one comes along, his 'optimal framework' becomes meaningless!"

"Hula~~"

The room erupted in an uproar.
