Chapter 246: What is an imaginary number

The voice of the Washington Times is not mainstream, but it has been making a lot of noise on the Internet.
What could be more topical than "racism"?
It can be seen that the owner of the gold behind has written the blood, and discussions can be seen everywhere on Twitter and Facebook.
Chinese overseas students and overseas Chinese groups naturally stand on the side of Lu Zhou on this kind of issue, but the black groups and the white left groups are clearly filled with indignation.
However, Lu Zhou didn't have many waves in his heart.
On the one hand, he didn't use Twitter and Facebook very much until now, and he didn't bother to see or worry about it. On the other hand, he had to do his own business every day and didn't have time to worry about the evaluation of foreign netizens.
Of course, even so, as he said, the war books were thrown to his desk across the board, and it was not like him to respond without responding.
Soon, it was the day of the report.
A few hours before the report, the land boat, which has arrived at Palmer Square, plans to eat something first.
It must be too late to eat at the Ivy Club. After all, the club is on Prospect Avenue, and now he is about half a mile away from Princeton.
I randomly found a Texas burger near Palmer Square. Lu Zhou was preparing to push the door and walked in. Hearing the sound of controversy.
I saw a black brother, standing in front of the counter, speaking in a voice full of superiority.
"The chicken thigh burger set is $ 6, the Texas grilled beef burger is $ 7, and the two set items are $ 35 and $ 4. And I noticed that a glass of cola on your menu is $ 1. "
"Although you do n’t price the free Texas BBQ steak, I got two values ​​through the simultaneous equations. That is, your Texas BBQ steak is both $ 15 and $ 2. So, you can explain , Is there a reason for the imaginary solution in your menu? "
The Texas guy standing behind the counter, drew his ears with his little thumb, and said impatiently: "So what?"
"So it's not reasonable," Professor Enoch said with confidence. "In Nigeria, the equations are something that anyone who has gone to high school can do. You sell burgers in Princeton, you don't even have to." ? "
The Texas Red Neck behind the counter was obviously too lazy to hang out with him, urging: "No matter what the imaginary number is, the imaginary number, if you want to buy it, then please pay, if you don't buy it, please bother you.
Although he wanted to use the word
roll
, after all, he still had to restrain his temper when he was still open.
Looking at this rude Texan, Yinot's eyes could not help but a sense of superiority.
This sense of superiority is probably similar to when he was at the Federal University of Ekiti.
A group of black boys who didn't understand anything were sitting in his classroom, and He who is omniscient is God, and all the satisfaction and joy he wants can be found in those who are lower or weaker than him.
This feeling is almost like poison.
However, Professor Enoch apparently did not realize that the situation here was probably different from that of Nigeria, and he did not even notice the playful sight cast from the side.
The Texans who stood in front of him were not the black guys who were hoping to learn something from him, and then changed their fate and fled the African continent. They were not interested in his doctrine at all.
As the Texas guy rolled up his sleeves and winked at the waiter and waitress next to him, a clear but small voice floated from the direction of the door.
"The system of equations is really not something advanced. I will learn in any high school in China ... give me a bacon sandwich and coffee, and I will have a briefing session a little bit sooner." A black brother, Lu Zhou put the money on the table.
Seeing the dollar, the Texas guy finally squeezed a smile.
"immediately."
Hearing the briefing, Professor Enoch raised his eyebrows, seemingly guessing the identity of the Chinese, and there was an interesting arc in the corner of his mouth.
I saw him relentlessly and asked.
"Then how do you explain the price on the package?"
"It's very simple. You have to formulate an equation to calculate this obvious thing. In this case, we generally consider adding a coefficient in front of the unknown. You can understand it as the so-called preferential margin." Lu Zhou shrugged and continued, "Of course, put two completely inseparable equations in curly braces and put together one to the wrong problem to calculate the imaginary solution. I'm also curious how you did it. Didn't your students tell you? ? "
Although the students sitting next to the meal did not mix in, many people have begun to laugh.
In fact, they didn't want to laugh when they saw the excitement. The reason why they kept mumbling was just to show the nasty ghost to the owner to show him how to solve the equation of the Texas Red Neck.
In mathematics, an imaginary number is a number of the form abi, where a and b are real numbers, and b0, i21. Where a is the real part and b is the imaginary part. Chinese high school students who dare not speak 100 will do, but 99 high school will definitely teach.
Talking about people is that the square is negative or the number within the root is a imaginary number.
In fact, as long as the nine-year compulsory education has been completed seriously, this is really not something esoteric, although it will not be shameful.
"He's right, that's what ... Preferential ratio, do I still need you to sell my own stuff?" The Texas guy waved his hand impatiently, put down his original sleeves, and knocked his index finger on the table. "You don't want to buy it. Give up quickly, you're blocking the guests behind."
The air was full of joy.
Enoch's face turned red, and he began to say some incomprehensible words: "On the basis of an equation, why can't I count an imaginary number? How do you know that in the Abelian group, homomorphism and conjugate classes, there is no such Imaginary numbers ... "
Hearing here, Lu Zhou could not help but help.
Although he really wanted to tell if he knew the true meaning of these proper nouns, obviously the point is not here.
The real slot is ...
"Do you still need to ask, because the equation does not need to be rooted!"
...
For Lu Zhou, what happened in the burger shop was just a small episode.
Although I was curious as to who the black brother was studying mathematics with, but finally his black face swelled completely into red, and the door burst out in the laughter of a group of people, so this issue is unknown.
Putting this aside, after Lu Zhou settled his lunch, he calmly arrived at the Princeton Hotel opposite Palmer Square.
Ralter stood at the door and greeted each guest with a smile, but when he saw Lu Zhou, he was obviously stunned, but soon changed into a smile.
But the smile was somewhat ironic.
"Welcome, a Chinese mathematician from Princeton, I didn't expect you to come here."
Lu Zhou glanced at the lecture hall, which was almost full, and said with a smile, "I'm probably not uninvited."
"You can't even laugh?" Ralter raised his lips and lowered his voice. "Hopefully, after an hour, you can still be as confident as you are now."
Lu Zhou smiled and said suddenly: "May I ask a question?"
Larter: "What's the problem?"
Lu Zhou asked with a serious face: "Who gave you the idea?"
Laart's expression stagnates ~ EbookFREE.me ~ but there is no obvious change, it is still the professional smile: "what an idea? What idea? Sorry, I don't understand what you are saying."
Lu Zhou smiled and said softly, "It's all right, forget it, when I didn't ask."
He certainly didn't count on what he could ask with a single sentence.
However, human subconsciousness is uncontrollable, especially when external factors guide it.
Ralt didn't waste time with him, or he didn't plan to waste a second on him, and turned to greet the legal persons and representatives of the black rights protection organizations, the gold owners who provided funds for these organizations, and the relevant lawmakers .
Most of the people sitting in the conference hall may not understand mathematics or even intend to listen to a scholar's defense of their research results. It was as if the New Yorker had misrepresented Qiu Chengtong's results and accompanied it with a photo that vilified the Asians, even if it was Hamilton who stood out to clarify it?
This is a place where populism, also called populism, can be seen in many places.
The reason for sitting here is purely because a Nigerian brother has been treated unfairly by the American academic community. It is purely because politics requires them to push out important meetings and pose in a sitting posture.
but……
What does this have to do with Lu Zhou?
Academic exchanges cannot be completed with knowledge of elementary mathematics. No matter how many discussions with Professor Enoch, it is also good for cattle sitting on the stage.
But some science-based things, even common sense things, can be done even in plain language.
Lu Zhou gently adjusted the tie on his chest.
For him, it wasn't really difficult.
