Without Umhera's Bauville Library, it looks deserted.

Lin Luo, who originally planned to pick a random book to spend this hour, was not in such a mood at all.

In his mind, the figure of um Hera was hovering all the time. The woman who smiled and had the atmosphere of the palace completely fell because of a collision at the staircase.

It wasn't until the game bell rang that Lin Luo pulled out of his chaotic emotions.

It wasn't until the documents were checked and the competition questions appeared in front of Lin Luo that he suddenly realized and exclaimed: "No wonder the examination room is set up in the Bao Wei Library, it turns out that the mathematical modeling this time is related to it." ”

This time, the assessment question is: through data modeling, calculate the support life of the third column in the corridor on the first floor of the Bauwell Library.

"Oh my God!" Lin Luo finished scanning the question at a glance, and was suddenly dumbfounded.

He looked up and saw that the examinees around him were more exaggerated than his expressions.

Now, he had a little more balance in his heart.

"How is this calculated?" Lin Luo's eyes rolled and he almost fell to the ground.

Just when all the students were at a loss, the examiner finally picked up a small and delicate laser sight and walked to the projector that um Hera had set up not long ago.

"Students from all over the world, please wear the simultaneous translation headset on the desk. He pointed the laser at the headset on the screen.

Suddenly, there was a rustling sound in the room. All the students followed the instructions and put on their headphones.

Lin Luo also picked up the headphones and put them on his head.

A pleasant sound rang out.

He is fluent in Chinese.

"Hmm!" Lin Luo listened to his voice and praised sincerely: "The simultaneous translation function is indeed first-class, and I can't even adjust the slightest problem." ”

"Look at the big screen!" the pleasant female voice sounded again.

Lin Luo immediately looked up at the screen.

In the screen, there is a bird's-eye panorama of the Bauwell Library. In the upper right corner is the Bauwell Library, one of the four core buildings on the North Campus, built in 1929.

Immediately afterwards, the screen turned to the column mentioned in the exam question.

The picture stretches until it is cast into a crack under the column.

The time period, length, width, and depth of the cracks are marked in detail.

Soon, the screen switches again.

All kinds of detailed data are presented on the screen one by one.

These data include soil composition data, air humidity, climate, rainwater acidity and alkalinity, and various raw data such as steel and cement used in the construction.

Every piece of data is densely packed and fills the big screen.

At the same time, there is also a simultaneous translation for detailed annotations in the speech.

It took a quarter of an hour for all the information to be announced.

After the announcement was completed, the door of the examination hall was pushed open.

"Wow!" exclaimed.

Lin Luo's eyes also widened in exclamation, staring intently at the door.

I saw a 200:1 model of the Bauwell Library, which was carefully pushed in by four stout middle-aged men.

The library model is housed in an enclosed glass case, with a metal cart attached below.

"This is a 200:1 architectural model of the Bauwell Library. The examiner walked up to the model, pointed to the glass cover outside the model, and said through the synchronous translator: "The glass cover outside the model is a holographic environment simulator pioneered by the School of Engineering of our university. It can simulate our real living environment. To put it simply, when you finish the exam, you can use it to verify whether your answers are correct or not. ”

"Ah!" exclaimed again in the examination room.

This time, even Lin Luo couldn't help but exclaim.

"Holographic Environment Simulator!" Lin Luo stared at the glass cover where various precision instruments were installed, and said secretly: "The instrument developed by the students of this school?

I have to admit that in the field of practical science, the United States is indeed ahead of China.

No, it's ahead of the world.

As soon as this instrument appeared, Lin Luo knew that this mathematical modeling exam was real.

Because, theoretically, mathematical modeling is mainly based on various data, establishing mathematical models, and then testing the final results through computer technology.

But after all, computers are only simulations, and although they have a certain authority, they will still have a big deviation when applied to reality.

And this holographic environment simulator, strictly speaking, is also a kind of simulation, but on the basis of the computer, it has taken a very heavy step.

The rigor it brings is naturally not comparable to that of a computer.

"Okay!" The examiner glanced at all the candidates and said, "The exam has officially begun, please open the notebook on the table and import all kinds of data on the big screen just now." ”

In the examination room, the sound of dense and compact keyboard tapping sounded.

Lin Luo looked at the mathematical modeling prototype that appeared on the screen, his brows furrowed deeply, and he fell into deep thought.

The so-called practical assessment is actually a mathematical structure. The difference is that this exam question is directly linked to reality, and finally tested by a realistic isometric model.

In other words, whether it is done correctly is no longer a theoretical calculation, but an deduction in a real model.

Such a change is indeed a severe test for Chinese candidates who are good at overcoming various mathematical propositions. In fact, not only Chinese candidates, but also candidates from almost all countries and regions have been severely tested.

Lin Luo remembered the conversation with Charlotte, and finally understood why Charlotte had the confidence to win over herself.

Presumably, he is at the University of California, and he has already carried out various mathematical modeling calculations through environmental simulators.

Does this count as the first month of the still water building?

It doesn't matter, though. For Lin Luo, this is challenging.

Mathematical modeling, in the final analysis, is mathematics. As long as it's a math problem, there's no shortcut. Right is right, wrong is wrong.

In the contest between Lin Luo, Zhang Hanlin and Charlotte, the comparison is still mathematical skills after all.

Two hours may seem like a long time, but for every candidate here, it is extremely short.

When the bell rang, a lamentation rang out in the examination room.

Lin Luo stopped the movement of his hand and stood up.

He looked at the model in the glass enclosure and said to himself, "If this crack really exists in the columns of the Bauville Library, then this building, if it is not maintained immediately, will collapse in 733 days." That's about two years. ”

Lin Luo really couldn't wait to see the pillar.

Presumably, all the candidates present also thought the same way.

"In China, there is a warning that 'a thousand miles of embankment, collapse in an anthill'. Unexpectedly, a small crack in the column can also cause a century-old building to collapse. Lin Luo's heart was surging, and he couldn't calm down for a long time.

When all the computers turned off automatically and all the students got up to leave, the examiner used the microphone to let everyone stay.

Immediately afterwards, the deputy director of the Federal Education Bureau, Arn Rijin, with a group of experts in suits and leather shoes, pushed the door in.

These experts, all in their fifties and sixties, almost all wore thick reading glasses, and each of them walked in front of the holographic environment simulator with a kind of academic rigor and solemnity.

After Arn Ruijin and these experts were in place, another team of personnel walked in.

Among them, there are reporters from the Los Angeles newspaper, the most authoritative newspaper in California, as well as the Washington newspaper, the New York newspaper, and more than a dozen well-known newspapers in the United States. The whole team has more than 30 people.

Lin Luo looked at this battle and was taken aback.

"No!" Lin Luo exclaimed in his heart: "Isn't it just an Olympiad competition?

Just when Lin Luo was puzzled, the examiner looked at the candidates and said in a loud voice: "All the candidates must be wondering whether the crack in this pillar exists. I'm here to tell you that it exists. ”

Rumble.

The audience was in an uproar.

"It's broken!" exclaimed one student, "I've calculated that the library will collapse in a week at most." ”

"I'm better than you, half a month. A student replied.

"Oh, I'm going to run!" exclaimed one black student, whose whole face was as white as paper, "I'm going to fall right away!"

In the examination room, many students were flustered.

The examiner had to say loudly: "Candidates, don't panic, this building won't collapse for a while and a half." ”

As soon as these words came out, some people settled down.

But at this time, an exclamation suddenly sounded in the crowd: "It's over, I will not fall until a thousand years later." This...... This...... This must be so wrong!"

"Hahahaha......" In the crowd, laughter rang out.

Many people were amused by this candidate's answer.

What kind of building can have such a long lifespan? I'm afraid that the ancient buildings in China don't have such a long lifespan.

"Experts, newspaper reporters!" the examiner said with a serious expression: "In order to let you know the severity of the Bauwell Library, and in order to better protect the Bauwell Library, we have to use this Olympiad to convince you." ”

The examiner pushed his glasses, and said in a deep voice: "In order to avoid another fierce conflict with you experts, Principal Hera has decided not to appear at the scene of this deduction. But her attitude has not changed. If you still don't agree to fund the maintenance of the Bauwell Library building, she will resign as headmaster!"

Rumble!

Lin Luo was shocked in his heart.

In an instant, he understood the true purpose of this mathematical modeling exam.

Thinking about it, Principal Hera discovered the severity of the crack and reported it to his superiors many times to apply for maintenance money. But the superiors never agreed.

In the end, we have today's scene.

"Resign from the position of headmaster?" Lin Luo sighed lightly, "Who else is more suitable than her?"

"Let's start!" The representative of the expert group glanced coldly at the examiner and said, "Since the holographic environment simulator you invented has passed the certification of the Ministry of Engineering, my side is naturally recognized." As long as the results of this exercise are consistent with the report you submitted, I will agree to your request for funding. However, if the result is wrong, Hera's headmaster is afraid that he will really not be able to sit down. ”

Lin Luo listened to the cold voice of the bald old man, and immediately felt the urge to beat him violently.

If you want to dismiss Hera, has he Lin Luo agreed?"Let's start!" The examiner looked at the four middle-aged people guarding the instrument, and said in a deep voice: "Let's start the holographic deduction!"
