Spring 2022, provincial capital.

"Who is Ye Ming?"

The March breeze carried the spring chill across the provincial campus, along the corridor of the science and technology center, and into the electromechanical laboratory on the third floor of the activity center.

The laboratory is quite large, about 80 square meters, and directly opposite the door is a workbench made up of four large desks, and on the side are seven or eight desks, which are piled up with various equipment, tools, electronic components and circuit boards.

Behind the laboratory is a spacious space of about 50 square meters, and there are two generator-like machines stacked on the floor.

This is a "dedicated" laboratory for the robot team of the Provincial Jiaotong University.

At this time, seven men and one woman were sitting at the workbench, each looking seriously at the notebook in front of them.

The picture of the notebook is a video of a blogger in the tech zone.

After watching the video, captain Li Dongsheng looked at the young player who was sitting furthest and added, "What major?" How hands-on is it? Do you have experience with robotics? Cow or not? ”

"Uh...... It's my roommate. ”

"Oh......" Li Dongsheng immediately became a little disappointed: "Freshman? ”

At this time, the only girl laughed: "Captain, it's good to have a newcomer come in, do you still pick?" ”

Li Dongsheng also laughed: "It's me who is in a hurry, we will not refuse to come, there is no class - Xuanxuan, you hurry up and urge your girlfriend, we can't do without a CFO!" ”

The girl named Xuanxuan smiled and took out her mobile phone.

Li Dongsheng coughed and looked at the rest of the boys: "I watched the video again just now, and the direction of this author's robotic arm is the same as that of our robot." What do you think? ”

As soon as they heard this, the team members looked at each other's noses and noses.

The reason is simple......

They watched this video, that author......

Too! Strong! Finish!

- "I spent a month making a robotic arm that can play table tennis"

Listen, is this human talk?

The arrogant title must be full of traffic, and the author does use a fast-forward way to show a robotic arm from design to completion, and finally complete the task of playing table tennis......

Therefore, in just one week, the number of views of this video exceeded one million.

Seeing that no one spoke, the deputy captain in charge of the mechanical part coughed lightly: "Ahem...... Captain, I think it's still a netizen's saying that is good. ”

"Which word?" Li Dongsheng looked down at the video comment area.

The comment section was full of praise.

"It can be seen that table tennis is really the national sport"

"I don't understand, but I'm shocked"

"Hope is not a cyber thimble"

"Roll it up! Tech Zone UP roll up! By the way, he also @ several other well-known bloggers in the science and technology zone.

……

The vice-captain smiled: "Let the bullets fly for a while." ”

- They are engaged in intelligent robots and robotic arms, and they don't know much about the technology and engineering required for this kind of robotic arm that can automatically receive the ball and can also be controlled synchronously.

A team of five people didn't think about it for three or two months.

Of course...... The premise is to build it from scratch, from design to source code to assembly to debugging.

Therefore, many netizens suspect that this is not the result of one person.

And the reason for such a title is nothing more than to create a character of "technological genius".

In the modern era where traffic is the head, what else is new?

***

Ye Ming walked around the campus holding his mobile phone.

Even if he was wearing a mask, he couldn't hide the smile on his face.

He's babbling.

As a budding UP master, his debut video reached a million views within a week.

In the science and technology zone, without selling meat and rubbing hot spots, this is already a general start.

Of course, the reason why the video has such a high popularity, in addition to the mechanical arm itself in the video has enough technical content, is more because his video is very controversial.

Not only did he not show his face in the video during the whole process, but even the copywriting voice was synthesized with AI - so much so that at the beginning, the audience was even sure that he was a marketing account, and the video was stolen from the "foreign god".

Later, after confirming that his video was original, someone soon compared him with the robotic arm of another UP boss in the science and technology area......

So naturally, the popularity of the video came up.

His follower count has also gone from single digits to five figures.

According to this rate of fan growth, I'm afraid that in less than two months, I will be able to eat smoothly, right?

"Brother, be careful."

Just as Ye Ming was stunned, he almost hit the glass door of the library headfirst - if it weren't for a buddy behind him pulling him.

"Uh...... Thank you. ”

Ye Ming's face flushed, and after saying thank you, he walked quickly to the second floor of the library.

As a science and engineering university, the library of the Provincial Jiaotong University is quite rich in science and engineering books, and Ye Ming easily found his goal.

A copy of Alexander Stepanov/Paul McTJones's Programming Originals.

A copy of Matrix Computation by Gene H. Golub and Charles F. Van Loan.

These two books are well-known in the field of algorithms and artificial intelligence, and can be regarded as textbook-level readings for graduate students in related majors.

As a freshman "new" student, the reason why Ye Ming can understand it is naturally because of ......

He has hanging.

……

Holding the book, Ye Ming's eyes swept over the audience and found that the entire second floor was already overcrowded, especially the single seat next to the bookshelf, and there was no vacancy.

Just when his face was full of disappointment and he was about to go to the cafeteria to make do, the girl sitting next to him suddenly picked up her mobile phone.

Ye Ming remained silent, and secretly aimed at the girl - according to experience, if he took his mobile phone, he planned to leave.

The girl clicked on WeChat, and it was a text message.

- Dear Xiao, come on, I'm waiting for you.

The girl smiled lightly and quickly typed in reply.

- Wait a minute, the last question, there is already an idea.

After replying to the message, the girl turned off her mobile phone and continued to do the question.

Ye Ming retracted his gaze with satisfaction.

Really!

This is urged by her boyfriend, and it seems that it is another relatively simple math three postgraduate examination problem, and it is estimated that it will take a few minutes for this senior sister to give way, right?

But as time passed, Ye Ming found that the girl's brows gradually wrinkled, and the pen in her hand gradually stopped.

At this moment, a girl wearing a yellow coat, a silk scarf, and a handsome gel pen in her hair glanced at Ye Ming very vigilantly, and then she touched the girl who was in trouble.

The girl looked up, and immediately felt Ye Ming's gaze.

Obviously, she had realized that Ye Ming had been standing beside her for a long time.

Ye Ming coughed lightly and whispered: "r(AT A)=r(A)"

"What?"

"The orthogonal transformation method is to convert the quadratic form to the standard type, the key is r(AT A)=r(A), and then solve the system of three linear homogeneous equations......"

Ye Ming whispered softly, his eyes looking at the pencil in the girl's hand.

The girl's face was full of astonishment, but in an instant she realized that Ye Ming was lecturing for her. Immediately, her face turned red, and she immediately handed the pencil and scratch paper to Ye Ming, and stood up at the same time.

Ye Ming is not polite, anyway, he has coveted this seat for a long time.

"After obtaining the eigenvector, the orthogonal matrix ...... is obtained by unitization"

Ye Ming took the pen and quickly wrote down the process: "The method you use, not to mention that the determinant is difficult to calculate, and it has to be factored after calculation...... Troublesome. ”

Girl: "......"

Ye Ming wrote down the answer to the second question.

“2y1^2+6y2^2”

The girl took the manuscript paper a little helplessly, and held back for a long time before whispering: "Thank you, senior brother."

"You're welcome." Ye Ming waved his hand and said in a low voice: "Do you still need this position?" ”

"Huh? No need. ”

"Thank you." Ye Ming took out the book from his lap and put it on the table.

Girl: "......"

As the girls hurriedly packed up their things and left, Ye Ming also opened "Matrix Calculation".

Then, he lowered his gaze and called softly in his heart.

"System"
