Chapter 367

All in one go, without any pauses.

Because the topic was too simple, Cheng Nuo easily got it.

Then, Cheng Nuo handed the straw paper with the complete steps to solve the problem to the still stunned classmate Chali, turned around, and left the place with He Youjun.

After a few seconds, Zarry's dull gaze gradually regained his expression.

Chari looked at Cheng Nuo, who was only left with a distant back, and muttered, "He...... Who the hell is it?"

............

At noon, He Youjun took Cheng Nuo to have lunch in the school cafeteria.

Although foreign university restaurants are more high-end than domestic ones, Cheng Nuowei is really not used to such tastes.

Cheng Nuo suggested to He Youjun that either we eat three meals a day at home.

He Youjun nodded and said yes!

After a few seconds of silence, Cheng Nuo asked, "By the way, do you know how to cook?"

He Youjun looked up.

The two looked at each other silently for a few moments, and consciously gave up discussing this topic.

Well, let's eat in the school cafeteria in the future!

In the afternoon, bidding farewell to He Youjun, Cheng Nuo came to a school building alone.

This is a laboratory that has just been built in recent years and is currently used by professors and students of the Faculty of Science.

Professor Fresnel and several of his assistants stayed in the laboratory.

The third floor of the laboratory is an area for mathematics majors. Since there is no need for large-scale specialized equipment like physics and chemistry majors, they are built to resemble large offices like a school building.

The scheduled meet-and-greet time is 2 p.m.

Cheng Nuo came to the third floor of the laboratory ten minutes early.

Professor Fresnel's office is at the entrance of the third floor, and when he pushes the door open and walks in, the scene inside is presented to Cheng Nuo's eyes.

The room area is very large, at least more than 200 square meters, and the structure of the whole room, at first glance, looks like a small-scale company structure.

First of all, there are more than a dozen desks, half of which are occupied by people, either facing the computer, or with their heads down, busy with something.

In the middle of the desk, which occupies about a third of the room, is divided into two compartments, one large and one small.

Except for the reception without a front desk, it's almost like a small company.

The sound of pushing the door sounded, and many people subconsciously raised their heads.

At the desk closest to the door sat a tall white boy.

He subconsciously looked up and saw Cheng Nuo standing in front of him.

"Hello?" he said, holding up his hand.

"Hello!" Cheng Nuo smiled back.

"I'm looking for Professor Fresnel. Cheng Nuo explained his meaning in English.

The white boy got up and smiled slightly, "It's just right, the professor is here today, come with me!"

The white boy led Cheng Nuo, walked past the dozen or so desks, and after receiving the glances of five or six foreign friends, he came to the door of the large cubicle.

Knock knock!

The white boy knocked lightly on the door, "Teacher, someone said they wanted to see you." ”

"I just thought of a good idea, and you interrupted me again!" A few mutters came from inside, followed by a voice that didn't seem to be very happy, "Alright, come in!"

The white boy shrugged, as if he had long been used to this, and pushed the door with Cheng Nuo and walked in.

It was also the first time for Cheng Nuo to meet Professor Fresnel, who is well-known in the mathematics community.

Just like in the photo, he has a lean figure, a dry complexion, a thick beard that grows long, and messy hair that looks like he hasn't been taken care of in months.

The clothes are fairly neat, otherwise you will really think you are a beggar if you are thrown on the street.

But his eyes were not as cloudy as those of his age, but incomparably bright, and seemed to have a faint glint of essence.

The white boy walked up to Professor Fresnel, "Professor, this classmate wants to see you." ”

Professor Fresnel glanced Cheng Nuo up and down.

Cheng Nuo took out a letter from his pocket and handed it to Professor Fresnel, "Professor, this is my letter of introduction. ”

Fresnel opened the envelope, looked down for a minute or two, then looked up and looked at Cheng Nuo with a smile, "It turned out to be a student sent by Huaguo." ”

Cheng Nuo nodded, "Yes, my name is Cheng Nuo." ”

Fresnel half-leaned back in his chair and said in a light tone, "I know this." ”

"Since you are a student sent by Huaguo, this assistant position will definitely be given to you. ”

"But!" Fresnel grinned, "but you know my temper." ”

He gestured outside the office.

Through the single-sided see-through glass wall, you can see the five or six busy figures sitting at their desks outside.

"The guys out there, and the Huffy standing in front of you, are all my assistants. And they all came here after layers of selection. ”

"So, compared to them, your assistant position is too easy to come by. ”

After hearing this, Cheng Nuo's expression did not change at all, because these were expected long before he came.

He shrugged his shoulders and smiled lightly, "So, Professor, am I going to take a test from you to prove my strength?"

Professor Fresnel gave Cheng Nuo a sensible look, "Yes, through my test, you are qualified to sit in the office outside like them." If you don't pass, I won't resign from your position as an assistant. However, during your tenure, I will not assign you any projects. ”

In this case, there will only be a false title left for my assistant position!

Except for taking it out and pretending to be forced, there is no use for eggs!

Cheng Nuo was very dissatisfied with Professor Fresnel's approach. But there is no way, Professor Fresnel is a super boss, and he has barely just stepped out of the new stage of Xiaomeng.

Besides, compared to the assistants like Hitch, who fought through layers of battles, he really came in through the back door.

Cheng Nuo was silent for a few seconds and grinned, "Professor, I accept your test!"

Professor Fresnel clapped his hands, "My test is simple, just one question. ”

"Excuse me, are all real numbers the roots of algebraic equations?"

"Huh?" Cheng Nuo was stunned, suspecting that Professor Fresnel was teasing himself.

Does this need to be proved? It's simply pointless, because all real numbers r are obviously the root of the algebraic equation x - r = 0.

Cheng Nuo was puzzled.

Fortunately, Professor Fresnel added, "Of course, there is a qualifier to this question. That is, the coefficients of each term (including the constant term) can only be rational numbers. ”

Thus, algebraic equations with this restriction should be called "algebraic equations on the field of rational numbers" to be exact.

This is also a question that Fresnel pondered when he was interrupted by a knock on the door just now.

Sitting in an office chair, he thought of this interesting argument. In his head, there was already a way to prove the problem.

"Professor, give me some time. Cheng Nuo spoke.

"Yes. Fresnel nodded, then leisurely picked up the thermos cup in front of him, ready to drink wolfberry tea.

Suddenly, I heard a voice from the side, "Professor, I've thought about it!"

Professor Fresnel holding a thermos cup hanging in mid-air: "......"

This gives a little time, and it means five seconds!

This Chinese student seems to be poisonous!
