I kidnapped an alien civilization

"I'm here for an interview. I want to interview teacher Li Mo of your school." Wei Xiaonian asked directly, he was eager to meet the teacher who proved Colraz's conjecture.

"Teacher Li Mo?" Jiao Xuefeng was very unfamiliar with this name, and he didn't remember that there was such a teacher in the school. But it's normal, every year the school recruits many new teachers, and he doesn't know every teacher.

"Wait a minute, I'll ask the dean of teaching to help you get in touch," he picked up the phone and said after a pause. "Why do you want to interview Mr. Li Mo, may I know?"

"Do you know the Collats conjecture?" An unfamiliar word popped out of the young reporter's mouth.

"Collats conjecture?, I don't know, I'm from a liberal arts background."

"Is Teacher Li Mo related to this conjecture?" Jiao Xuefeng frowned and asked.

"The Collats conjecture is a difficult problem in mathematics. It was proposed in 1927. In 1930, Collats of the University of Hamburg in Germany studied this conjecture, hence the name." Wei Xiaonian was surprised that the high school principal in front of him did not Know the Collats conjecture.

"Teacher Li Mo proved him out." He added.

"Teacher Li Mo solved a difficult problem, so why did you come to interview him?" Jiao Xuefeng didn't understand the young reporter's train of thought.

"That's not necessarily a simple problem." Wei Xiaonian was very dissatisfied with Jiao Xuefeng's use of a problem to define the Collats conjecture.

"It is a difficult problem that countless Chinese and foreign mathematicians have not broken through for nearly a hundred years."

"Goldbach's conjecture, you always know, they are all unsolved mathematical problems in the world."

Although the Collats conjecture cannot be on the same level as the Goldbach conjecture, it is indeed an unsolved problem in the world. It is not wrong for Wei Xiaonian to say this in order to elevate its status.

"Goldbach's conjecture?" Jiao Xuefeng was shocked and sat up from the sofa. Although he majored in liberal arts, he still knew the story of Chen Jingrun and Goldbach's conjecture.

"Our Mengcheng No. 1 High School has a teacher who solved the "Goldbach Conjecture." Jiao Xuefeng couldn't sit still. This is a major event in Mengcheng No. 1 High School. As the principal, he didn't know about it, which is too negligent of his duty. He thought to himself that he must find this teacher Li Mo immediately.

He led Wei Xiaonian to the dean's office, and before the dean could speak, Jiao Xuefeng asked eagerly, "Let Teacher Li Mo come over."

"Teacher Li Mo?" The dean's chubby face looked a little dull.

"Yes, Teacher Li Mo, call him and ask him to come here immediately." Jiao Xuefeng emphasized his tone, he was dissatisfied with the dean's performance.

"We don't have a teacher named Li Mo in our school," said the dean, seeing that Principal Jiao was angry, and came back to his senses. Explained right away.

"Are you sure?" Jiao Xuefeng's heart was more than half cold. How could there be no teacher who solved "Goldbach" in the school? It must be impossible.

"Sure, the names of all the teachers in the school are imprinted in my mind" said the dean, pointing at his fat brain with a fat finger, as if his head was a computer.

Jiao Xuefeng turned suspicious eyes to reporter Wei Xiaonian.

"Impossible!" Wei Xiaonian took out a copy of the thesis that he carried with him, pointed to the cover and said, "Look, it clearly says Li Mo, Class 1, Class 3, Senior High."

"But I didn't say it was Li Mo, the teacher. Couldn't it be Li Mo, a student from Class 1 and Class 3?" Jiao Xuefeng seemed to have seen a life-saving straw.

"This thesis written by the student is impossible!" Wei Xiaonian rolled his eyes at the unprofessional principal. The logic of this thesis is clear, the deconstruction is rigorous and concise, and there is not a single redundant word. If it hadn't been for more than ten years in the field of mathematics It is simply impossible to write a paper of this high level.

"Ask the head teacher of Class One and Three, and you'll know? Last semester was Class One and Three, and this semester should be Class Two and Three." The dean next to him saw the two quarreling, and came up with an idea. He looked at the clock hanging on the wall and said, "School just started today, although school is over now. The teachers should still be in the office, so let's go now."

In the homeroom teacher's office, Li Mo stood with his head down in front of Teacher Wang. On the desk was his empty homework book. He already has a lot of experience in being scolded now. When the teacher scolds you, you just need to treat it as a song. The teacher is singing, you show an expression of intoxication, and then nod frequently, and the teachers will soon lose Train your desire.

Teacher Wang didn't know whether he was tired of talking or was conquered by Li Mo's "performance". He just sat at the desk and drank his tea, ignoring him.

"Tsk tsk, there are talents from the second and third grades of high school. I didn't do any summer homework, so I am worthy of being a student in the second and third grades of high school." A middle-aged woman with makeup and powder on the next table said contemptuously.

"Mr. Gu, I'm educating my students. Please don't intervene. Thank you." Teacher Wang said angrily. It seems that he still defends his students very much. He is the only one who can criticize his students.

"It's impolite to jump in when someone else is talking," he added.

"This is the teachers' office, principal, and journalists, please come in." The dean let the two of them into the office.

"Director Biao Gu, Principal, why are you here?" The sharp-eyed Teacher Gu hurried up to meet him.

The dean ignored her and went straight to Teacher Wang's desk. He asked, "Mr. Wang, is there a student named Li Mo in your class?"

"Li Mo. Yes, there is a student named Li Mo in our class. What happened?" Mr. Wang answered again and again, glancing at Li Mo who lowered his head.

"Great, you invited Li Mo here, I have something to ask him." Principal Jiao suddenly became excited.

"Oh, this is Li Mo." Teacher Wang pointed to Li Mo who was next to him. Seeing the principal's happy face, he thought it was not a bad thing.

"You are Li Mo? Li Mo from Class 2 and 3 of high school?"

"Did you submit a manuscript in the "Mathematics Monthly" called "On" For each positive integer, if it is an odd number, multiply it by 3 and add 1, if it is an even number, divide it by 2. In such a cycle, you can finally get 1."The conclusion is established."." Before the principal could question him, Wei Xiaonian rushed forward and asked.

Wei Xiaonian's speech speed like firecrackers coupled with uncommon mathematical terms confused the people around him.

"Yes, I submitted a manuscript to the "Mathematics Monthly" a few days ago, but I haven't received a sample manuscript yet." Li Mo came back to his senses, thinking that the paper had been published.

"It's really you?" Wei Xiaonian showed an expression of disbelief.

"It should be. It's really me." Is this still pretending? Li Mo didn't understand the exaggerated expression of the rider in front of him.

"In the paper, n+(n+1)/2 is an odd number, and ×2+×1+1 2n+n+1+n+(n+1)/2+1 is an even number, divided by 2 2n+1+(n What is behind +1)/4?" Wei Xiaonian has studied the paper in depth, and he thinks this is the essence of the paper.

"Continue the two cases, it is an even number, it is an odd number, and if it is an even number, it will cycle ① and ②, (anyway, the number is decreasing when it is an even number), until 2n+1+(n+1)/4 is an odd number. Transform to n+( n+1)+(n+1)/4, because: n is odd, n+1 is even, and only (n+1)/4 is even, n+n+1+(n+1) Only /4 can be an odd number." Li Mo replied without thinking, "Do you want to continue, there are many more in the future."

"It's really you!" Wei Xiaonian was so excited that he couldn't speak, "No, I have to call the editor-in-chief first, I found Li Mo." He took out his mobile phone and walked out, leaving Several people looked at each other in blank dismay.

"Have you solved the Collats conjecture?" Mr. Wang could stuff a duck egg into his mouth, and he understood what the reporter said.

"It should be considered. I proved that topic, then wrote a paper and sent it to "Mathematics Monthly." Li Mo said calmly, now he knew that these people came for that paper.
