I may be a pseudo-scholar

Chapter 28 Willow Dark Flower Bright Another Village

Looking back on yesterday, there were some colorful lights and shadows in the days, and the scene of Liu Wei's face covered in shit but nowhere to find paper in the barrier of Bai Xue's memory has gradually faded away.

What was fixed in front of Bai Xue was an old man with a short and stiff mustache, and a pair of brown eyes were constantly looking at Bai Xue, as if he was examining a criminal.

"I looked at your file, which includes your preliminary results. Your preliminary score is 148, ranking third in Bincheng City. If you perform normally, there is no big problem entering the provincial team with this result." The old man said leisurely.

Bai Xue didn't dare to be careless, he just looked at the old man and listened carefully, not daring to interrupt.

Bai Xue saw the identity of this old man when he entered the competition association.

President of the Provincial Mathematics Contest Association, Doctoral Supervisor of the Department of Mathematics of Northeastern University, Visiting Professor of Daliao University, author (here to omit [-] words...)
People with such brilliant resumes never expected to be able to have a one-on-one conversation with Bai Xue, which made Bai Xue flattered.According to his thinking, it should be that the old man randomly recruited a competition teacher to invigilate him to finish yesterday's paper.After all, there are not a few gold-medal math coaches in the association, so why do you need this most powerful old man?

The old man looked into Bai Xue's eyes and said sincerely: "No one could have expected the unexpected situation in the rematch. I would like to apologize to you on behalf of the entire competition academy."

"Apologize to me? What do you mean?" Bai Xue felt a deep sense of conspiracy.

The old man said regretfully: "However, according to national regulations, re-examinations, make-up exams, and re-examination opportunities are not allowed in competitive exams, so we are also sorry, Bai, your score in the semi-finals may be 0." .”

"What?" Bai Xue's head suddenly went blank.

???

What do you mean by not allowing make-up exams?Doesn't this mean that the provincial team is out of luck?What do you mean by not allowing make-up exams?If you don't let make-up exams, what do you ask me to do today?Could it be that I came to see the glory of you, an old man, don't pretend to have a resume?
I rely on!

Bai Xue suddenly thought of the price of failing in his mission, and couldn't help but feel his head getting a little dizzy.

The mission failed, but it took a leg!This leg is half the life of a man!

However, the old man changed the subject and said:

"However, judging by your file results, you are capable of entering the provincial team. Therefore, the association decided to give you another chance. After all, the goal of our provincial team is the country. The stronger the provincial team, the more honor our province will have. .”

"What opportunity?" Bai Xue couldn't help it, his eyes lit up, and asked.

How to say this: mountains and rivers are full of doubts, and there is no way out, and there is another village with dark willows and bright flowers!The old man's words made Bai Xue see hope again.

The old man stood up, found a piece of paper and a pen from somewhere, and put them on the table in front of Bai Xue.

"I'll give you a few questions to test you, and if you can answer one, you'll be considered a passer."

"One?" Bai Xue suddenly hesitated.

From the tone of the old man, it is obvious that the question he asked is not the kind of brainless question where 1+1 equals 2. Since he can answer one question, he will pass the test. One can imagine the difficulty of this question!

However, the arrow was on the string and had to be fired.If you don't answer, it means that you will miss the happiness of your lower body. If you answer, there may be a glimmer of life.It's just... What hurts Bai Xue's heart is that the 500 points spent last night should be in vain.

"Good teacher, tell me." Bai Xue picked up the pen, looking like a strong man gone forever.

"Don't be so nervous, listen to the question and just say it once." The old man said with a smile.

"Qinghan said that this kid is slippery, and told me not to let it go. I am the chairman of the association, how can I let the students go? After all, it is not so easy to join the provincial team."

The old man thought to himself, and his eyes instantly regained their clarity.

"Listening questions, a total of six questions, corresponding to: Algebra, Geometry, Number Theory, Inequality, Logical Reasoning, Calculus, the interval between each question is 30 seconds, after reading all six questions, you have four 10 minutes to answer the questions."

"Four 10 minutes?" Bai Xue thought for a while, and four 10 minutes was only enough for him to do the first two big questions, provided that these two answers were of the difficulty of the rematch.

“第一题：若存在一组数k1=k2=k3=…km=0使得k1a1+k2a2+…+kmam=0成立，则向量……”

The old man spoke very fast, as if deliberately making Bai Xue unable to understand.

When Bai Xuegang wrote "If k1=...=0", the old man had already started to read the next question.

"Damn, I can't remember it at all." Bai Xue suddenly realized that maybe the old man didn't want to give himself the time to copy the questions from the very beginning.

"Question 1: Let e2 and e1 be a set of orthonormal sets of the inner product space, and α and β are any two non-zero vectors. If a linear transformation T of (1, 1, [-]) on the space satisfies... ..."

It was extremely fast again, before Bai Xue could hear it clearly, it was time for the next question.

"Aren't I going to geometry? Oh, I'm rubbing, analytical geometry?" Bai Xue thought that it was a geometry problem about squares and circles.

"Third question, write a proof of a corollary or hypothesis that has not yet been proven."

This question only has [-] words. It seems to be the simplest question, but anyone who studies mathematics knows what a mathematical problem is. The fewer words in the question, the difficulty of this question is basically proportional to it!
Especially the third question, seventeen characters, but it can be said to be the most difficult question among all the current questions.

After all, you can calculate the answer to the first question, and you can also calculate the answer to the second question. This is based on the previous people who have already calculated the answer.And the third question is what to do, and the third question is to ask you to prove inferences or assumptions that have not been proved by previous people.

After finishing the third question, the old man smiled embarrassedly.He also knows that this question is indeed a bit... But he also wants Bai Xue to do this question at all. After all, the general number theory questions are so long and there are a lot of symbols. Dry tongue.

"Question 1, suppose x, y, z are positive real numbers, and x+y+z=1, m, n are positive integers and not [-] at the same time, to prove: x to the m power *y to the n power..."

Another big pile of numbers that Bai Xue didn't understand.

"Old man, are you posing a question or reading tongue twisters?" Bai Xue didn't want to listen to the old man's nonsense anymore, because he had already found his goal.

That's right, it's the third question!

Bai Xue let out a hearty laugh.

What do you mean it takes no effort at all?What is another village?
The third question that seems to be the most difficult, in Bai Xue's eyes, is a question that even a fool should know!
Unproven inferences?
Others may not have it, sorry, I learned here for nothing, and there really is one!
The "3X+1" inference proof method, at this moment, finally shines with its dazzling brilliance!
