"The refining system is no longer good, as long as the system that is slightly beyond this era will be crushed into nothingness by the will of this world."

"And systems like March grass are basically useless. It seems that I still need to slowly improve the scientific level of the country. ”

In order not to make himself look too super-god-like, Ji Zhen still needs to cover it up.

"But first, I'll start a Weibo."

In the past, Ji Zhen disdained to open Weibo. After all, Weibo has almost become a gathering place for celebrity fans, and the entire Weibo is basically built on celebrities and their fan effects.

From time to time, there will be fans tearing up for their respective idols, so Ji Zhen feels that the atmosphere on Weibo is not very good.

However, this is not the case now.

Now Ji Zhen's identity and status are not comparable to those in the past, even if he opens Weibo, he can ensure that his Weibo is not disturbed.

Weibo doesn't know how many times I discussed with Ji Zhen about opening Weibo, but Ji Zhen always refused.

And this time, Ji Allah moved to apply to open Weibo, and Sina soon began to operate.

Ji Zhen didn't take any other nickname, it was his own real name, Ji Zhen. But the avatar is a photo of Xu Linfei.

As for the words and sentences for certification, it is: Ji Zhen, a professor in the Department of Mathematics and Physics at Yenching University.

Sina attaches great importance to Ji Zhen's entry and directly pushes the news to Weibo users.

On top of the latest Weibo hotspot, it is the news that 'Professor Ji has settled in Weibo'.

In an instant, this news exploded tens of millions of netizens who were scrolling through Weibo. Even netizens who are not playing Weibo have heard the Didi voice of Weibo pushing messages.

Then, they all poured into Ji Zhen's Weibo.

Ji Zhen looked at the Weibo on his mobile phone, the number of comments grew rapidly, and the corners of his mouth were also smiling.

"It seems that not all of today's young people spend their energy on those celebrity gossip."

However, when Ji Zhen looked at the specific comment, it made him speechless for a while, crying and laughing.

"Mathematics and physics are simple Ji big guys."

This is the highest comment at the top, and the follow-up of this comment is also very neat, like a family.

"Mathematics and physics are simple Ji big guys."

"Mathematics and physics are simple Ji big guys."

"Mathematics and physics are simple Ji big guys."

This stalk was created by netizens when "Longing for Life" was broadcast, which also means that he Ji Zhen has also become one of the evergreen Ivy League bosses.

He didn't expect that after three months, this stalk has not passed, and it has been posted on his Weibo.

This one has the most comments, and there are all kinds of comments in the back.

Ji Zhen rubbed his chin, he was thinking about what he should post on the second Weibo. Because the first one was sent by Sina by default.

"My Weibo is not here to share my life status, nor is it to be the Discipline Inspection Commission of the entertainment industry, I am using this Weibo to share knowledge."

Tao Zhexuan often shares mathematical knowledge above death, which is worth learning from Ji Zhen, so he moved this point over.

"In that case, I'll try the water with two questions first."

In the speech on Weibo, many mathematical symbols could not be typed, so Ji Zhen wrote the topic on paper with a pen, and then took a photo and sent it.

After a while, netizens on Weibo found that Ji Zhen had posted another Weibo.

Many netizens were stunned when they saw the sentences above the comments.

"Test everyone with two questions, and show you the solution after three days."

Below this sentence, there are two photos, one photo and one title.

1. Specifically give the algebraic isomorphism CS 3 → C× C× M2 (C), where CS 3 is the group algebra of S 3; And give the corresponding arguments. Tip: Take advantage of irreducible representations.

2. Let V, is the Banach space, B:V×→C is about a bilinear functional that is continuous for each variable, i.e., for any ξ∈V, B(ξ,·): →C is a continuous linear functional and for any η∈V, B(·,η): V→C is a continuous linear functional. Proof: B is continuous.

In these two questions, the front is algebra and the back is analysis.

The questions are actually not difficult, which is equivalent to the difficulty of the doctoral exam.

Ji Zhen never considered the difficulty of the problem, but the mathematical thinking brought by the question.

Under this Weibo, more netizens are here to join in the fun. For example, the comment with the most comments and likes.

"Big guy, excuse me, farewell!"

"Big guy, excuse me, farewell!"

"Big guy, excuse me, farewell!"

It's the same format again, neatly like a family. There are also a lot of comments with the same meaning in the back.

"The big guy deserves to be the big guy!"

"I know every word, even two words together. But when it comes to connecting in one sentence, I don't understand it at all. ”

"I have always known that Professor Ji is very strong, but I didn't expect that in this Weibo occupied by the entertainment industry, Big Guy Ji would also use his mathematical knowledge to give me a painful blow."

"When I saw Professor Ji's title, I felt like a retard."

“···”

Of course Ji Zhen won't take these comments seriously, these people are all here to shake their wit.

He believes that there are many people who should be answering these two questions.

The topic is open, even if you don't understand it for a while, but you are not in a hurry, anyway, there is a textbook for reference.

After posting two questions, he read the comments a little, and then he turned off Weibo.

If it was not bad as expected, Xu Linfei was about to call over.

Sure enough, in less than ten seconds, the phone rang.

"Husband, why did you open Weibo? Didn't you say before that Weibo was too angry? ”

Ji Zhen nodded first, agreeing with Xu Linfei's words. But the next moment he realized that Xu Linfei was not by his side.

"Yes, Weibo is a bit angry. However, I did not enter Weibo for publicity, but for the role of an open class. ”

"Besides, what is your husband and I's identity and status! Those rhythms on the network will be controlled. ”

Xu Linfei exhaled on the phone, she knows too well the power of keyboard warriors, trolls and bar spirits on the Internet, and she is a good hand with rhythm!

"That's too, husband, you're so good, I think someone on Sina Weibo will definitely be staring at it."

Xu Linfei's words are actually to the point.

Sina Weibo.

The company's chief operations officer is very excited about Ji Zhen's entry, because it means that Weibo has one more traffic channel.

"Send someone to keep an eye on Professor Ji's Weibo, and if someone takes the rhythm, directly delete the comments and ban the account."

"How long has it been forbidden?" The person below asked a silly word.

"How long is it forbidden? Permanently, of course! The account was deleted directly from the database. ”
