Chapter 367

in one go, without any pause.

Because the topic is too simple, Cheng Nuo easily solved.

Then, Cheng Nuo gives the paper with the complete solution steps to Chali, who is still in a daze. He turns around and leaves here with he Youjun.

After a few seconds, Chali's dull eyes gradually recovered.

Looking at Cheng Nuo, who only left him a moving back, zari murmured, "he Who is it? "

…………

At noon, he Youjun took Cheng Nuo for lunch in the school canteen.

Although foreign university restaurants are more upscale than domestic ones, Cheng Nuo is not used to this kind of taste.

Cheng Nuo suggested to he Youjun that we should eat three meals a day at home.

He Youjun nodded and said yes!

Silence for a few seconds, Cheng Nuo asked, "by the way, can you cook?"

He Youjun raised his head.

They looked at each other in silence and consciously gave up discussing this topic.

Well, I'd better eat the school canteen in the future!

In the afternoon, after saying goodbye to he Youjun, Cheng Nuo came to a building in front of the school alone.

This is a laboratory just built by the University in recent years. It is currently used by professors and students of the College of science.

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

The third floor of the laboratory is the area for mathematics majors. Because it does not need to use large-scale professional equipment like physics and chemistry, it is built like a large office like a teaching building.

The scheduled meeting time is two o'clock in the afternoon.

Cheng Nuo arrived on the third floor of the laboratory ten minutes in advance.

Professor Fresnel's office is at the entrance of the third floor. Push open the door and walk in. The scene inside is presented in Cheng Nuo's eyes.

The room area is very large, at least more than 200 square meters. At first glance, the construction of the whole room 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 computers or lowering their heads. They are busy with something.

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

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

There are many people who raise their heads subconsciously.

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 raised his hand.

“Hello！” Cheng Nuo smiles back.

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

The white boy got up and said with a smile, "it's just that the professor is here today. Come with me."

The white boy led Cheng Nuo through the dozens of desks. After receiving the gaze of five or six foreign friends, he came to the door of the big compartment.

Dong Dong Dong Dong!

The white boy knocked on the door, "teacher, someone said to see you."

"I just thought of a good idea, but I was interrupted by you again!" Inside came a few murmurs, and then a voice that seemed not very happy rang out, "OK, come in!"

The white boy shrugged, as if he had been used to it, and walked in with Cheng Nuo.

Cheng Nuo is also the first time to see this famous professor Fresnel in mathematics.

As in the photo, he has a lean body, a dry complexion, a long bushy beard, and messy hair that seems to have not been taken care of for months.

The clothes are clean and tidy, otherwise they will be regarded as beggars if they are thrown on the street.

However, his eyes are not as muddy as his age, but incomparably bright. It seems that there is a faint light shining through his eyes.

The white boy came up to Professor Fresnel and said, "Professor, this classmate wants to see you."

Professor Fresnel looked Cheng Nuo up and down.

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

Fresnel opened the envelope and looked down for a minute or two. Then he looked up and looked at Cheng Nuo with a smile. "It turns out that they are students from China."

Cheng Nuo nodded, "yes, my name is Cheng Nuo."

Fresnel half reclined on the back of his chair, and said, "I know that."

"Since you are a student from China, the assistant position will certainly be given to you."

"But Fresnel laughed, "but you know my temper."

He pointed to the outside of the office.

Through the one-sided perspective of the glass wall, you can see the five or six busy figures sitting at the desk outside.

"These men outside, and hutch standing in front of you, are my assistants. But they all came here after selection. ""So it's easier for you to get this assistant position compared to them."

After listening to these, Cheng Nuo's look did not change, because these were expected before he came.

He shrugged and chuckled. "So, Professor, am I going to take a test from you to prove my strength?"

Professor Fresnel gave Cheng a sensible look, "yes, you are qualified to sit in the office outside like them only after passing my test. If I fail, I will not quit your assistant position. It's just that I won't assign you any projects during your tenure. "

OK! In this way, his assistant position is only a virtual title!

It's no use except taking it out and pretending to be forced!

For Professor Fresnel's practice, Cheng Nuo is very dissatisfied. But there is no way, Professor Fresnel is a super big guy, and he, barely out of the new stage of Xiaomeng.

Besides, compared with Hutch's assistant, who was fighting at all levels, he really came in through the back door.

Cheng Nuo is silent for a few seconds, grinning, "Professor, I accept your test!"

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

"Please answer, are real numbers the roots of algebraic equations?"

"Well?" Cheng Nuo is stunned and suspects that Professor Fresnel is teasing himself.

Does this need to be proved? It's simply meaningless, because all real numbers R are obviously the roots of the algebraic equation X-R = 0.

Cheng Nuo is puzzled.

Fortunately, Professor Fresnel went on to add, "of course, there is a qualification for this subject. That is, the coefficients of each term (including constant terms) can only be rational numbers. "

In this way, the algebraic equation with this restriction should be exactly called "algebraic equation on rational number field".

This is also a question that Fresnel thought when he was interrupted by a knock at the door.

Sitting in his office chair, he thought of this interesting argument. There was already a way to prove it in his mind.

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

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

All of a sudden, he heard a voice from the side, "Professor, I think well!"

Professor Fresnel, hanging in mid air with a thermos cup:.... "

This gives some time, specially refers to five seconds!

This Chinese student, it seems, is poisonous!
