Omnipotent Data

Chapter 368

Professor Fresnel slowed down for three or four seconds before he forced himself to show a "senior" smile.

He stroked his beard and gestured, "Please start your performance."

Cheng Nuo sorted out some thoughts in his mind, and spoke every word after two or three seconds.

"Regarding the question of'whether real numbers are the roots of algebraic equations', we must first determine clearly. All rational numbers q are the roots of algebraic equations xq=0. And, as long as anyone who has studied quadratic equations in one variable knows, Although all coefficients are restricted to rational numbers, the roots of algebraic equations are not necessarily rational numbers."

"For example, the two roots of x2-2=0, √2 and -√2, are irrational numbers."

After a pause for a few seconds, Cheng Nuo cleared his throat and continued.

"Real numbers include both algebraic numbers and transcendental numbers. Rational numbers and √2 are examples of algebraic numbers; e and π are examples of transcendental numbers. Our problem uses this new term,..."

If this problem is figured out, it is actually very simple.

The key point is to introduce the concept of transcendental numbers, that is, numbers that cannot be represented by the roots of algebraic equations.

The most common are the two numbers π and e.

Cheng Nuo continued his performance, "In 1874, the German mathematician Kantor proved that transcendental numbers are far more than algebraic numbers. It is very simple and can be proved by eloquent means that not all real numbers are algebraic equations. root!"

Cheng Nuo gave a negative answer.

After speaking, he raised his head and smiled at Professor Fresnel sitting on the office chair.

Professor Fresnel spent half a minute digesting what Cheng Nuo said.

Although Cheng Nuo's thinking is not the same as the one he had thought of solving the problem, the great way is the same. From Cheng Nuo's method, he can't find any flaws.

After half a minute, he raised his head and met Cheng Nuo's gaze, his thin face opened with a grin, "Yes, much better than I thought."

"So now..." Professor Fresnel got up and stretched out his hand, "Welcome to join my team!"

Cheng Nuo smiled and shook hands.

"Today you will get acquainted with the environment first, and you will start to work tomorrow!" Fresnel said.

Cheng Nuo nodded, the attitude of the staff to the boss, "Yes."

Professor Fresnel signaled to the white boy Hull, "Hull, take this Chinese classmate out. Tomorrow we will come to discuss which project he should join."

"OK!" Hull nodded, nodded to Cheng Nuo, and walked out of this office.

Outside the office.

Hull turned his head and smiled at Cheng Nuo, and asked familiarly, "I was very nervous just now? Fortunately, you passed the teacher's test. Otherwise, with his temper, it is really possible for you to sit on the bench until the end of your post."

Cheng Nuo smiled easily, "It's okay!"

"That's right." Cheng Nuo stretched out his hand, "please take care of it in the future."

Hull shook hands, "Of course, we are a team after all!"

He pointed to several empty desks in the room, "Choose one. It is estimated that you will treat this place as your second home for a long time to come!"

Cheng Nuo chose a position by the window, and there were several pots of succulent potted plants on the window sill.

"This was made by Sylvia. We rough men don't take care of this thing." Hull explained.

After Hull finished speaking, there was a tall girl with blonde hair in a ponytail and blue eyes, and came over, "Hull, I haven't settled the matter with you last time. I just went out to communicate for a month. Four pots of eight potted plants were raised by a few of you, hum, lose money!"

"Isn't that the reason that Henry that guy mistakenly used the drink for water, I won't recite this pot!" Hull smiled helplessly.

Sylveer also saw Cheng Nuo, her beautiful eyes suddenly lit up.

Sylver's eyes motioned to Hull, "Who is this handsome guy?"

Even from the perspective of Sylver's Western aesthetics, Cheng Nuo is also a very handsome guy.

Hull introduced, "Oh, this is Cheng from China, a newly recruited assistant teacher."

"Hello, handsome." Sylver blinked.

"Uh, hello." Cheng Nuo smiled lightly.

Sylveil fluttered with her shining eyes, holding her cheeks, "You look so young, are all Chinese men with such small meat?"

Cheng Nuo was full of expressions, "No, in fact, we Chinese men are still very manly! And me, I am only twenty years old this year, so, um."

The twenty-four-year-old Sylver's face was taken aback.

Twenty years old?

"Are you not a doctoral student?" Even Hull couldn't bear to ask this time.

Cheng Nuo shrugged, "Re-introduction, my name is Cheng Nuo, I am from China. I am studying at Tsinghua University and am currently preparing to study at MIT."

"So." Cheng Nuo looked at the two. "Senior, senior sister, in the future, I will trouble you to take care of my junior brother!"

…………

In the evening, He Youjun took Cheng Nuo to eat a luxurious dinner in a high-end western restaurant, in the name of celebrating Cheng Nuo's successful appointment as Professor Fresnel.

In the future, with this title alone, Cheng Nuo will be able to walk sideways in the entire world universities.

"I really envy you. Before entering school, I held such a thigh!" He Youjun said while chewing on a steak.

Cheng Nuo didn't agree, "I don't know if I was holding a thigh or a time bomb?"

Just with the attitude of meeting Professor Fresnel for the first time today, I am afraid it will not be too comfortable in the future.

"Just relax, you have to believe in yourself." He Youjun cheered Cheng Nuo, "your strength lies there. It is not an exaggeration to say that you are crushing contemporary mathematics. Besides, you are still young."

"Wait for you to hold the Fields Medal trophy in your left hand, hold the proof paper of Goldbach’s conjecture in your right hand, and hold in your pocket the $1 million bonus after the proof of Riemann’s conjecture given by the Clay Institute. See who else Dare to look down on you?"

Cheng Nuo thought about the life of a mathematics tycoon described by He Youjun in his mind, and found that it was really cool!

Then ~www.readwn.com~ just roll up your sleeves and do it!

"Oh, by the way, let me tell you something." He Youjun suddenly seemed to think of something important.

Cheng Nuo looked up, "What's the matter?"

"Next week there will be a party organized by our Chinese students. By then, most of the Chinese students studying in Princeton will go back. Are you coming?"

"I suggest you go there if you have time. After all, they are all Chinese and get to know each other. In short, there is no loss."

"Let me ponder and ponder." After Cheng Nuo finished speaking, he immediately replied, "Go!"

He Youjun's fork trembled.

Brother, your operation is a bit shameful!

He nodded, "Well, we will go together then."
