The next morning, the first ordinary differential equation class was held.
When Lu Zhou entered the classroom, he felt that the atmosphere in the classroom suddenly became a bit strange.
The first and second classes of applied mathematics usually had the same class. Now that the students from both classes were sitting here, the classroom was filled to the brim.
Being stared at by so many pairs of eyes made Lu Zhou feel a bit nervous.
Not to mention, these stares were accompanied by whispers.
"Wow, Lu Zhou from mathematics!"
"The genius student who scored full marks in advanced mathematics!"
"Advanced mathematics is nothing, he even proved the conjectures in the textbook! It's easy to get full marks! "
"Also, it's a graduate student textbook …"
"Sigh, don't be jealous of him. I heard from a guy in the student council that this guy didn't go back for the entire summer. While we were playing League of Legends, this bro was grinding books in the Building of Building A every day. "
"Oh, he's from the Gate of Heaven … I'm afraid he's about to go through a calamity."
"I'm … shocked!"
F * ck me, can these animals lower their voices when they talk about other people.
But it's still pretty cool.
At this moment, the teacher arrived.
Lu Zhou knew the professor who came into the classroom. It was Professor Liu Xiangping, who took him to the data modeling competition.
This old man had a unique style of coming to the classroom. He was never a second late or a minute early.
"What are you standing there for, class is about to start. Find a seat," said Professor Liu as he smiled at Lu Zhou. He then placed the vacuum flask on the podium.
"Uh, I just got here."
Lu Zhou smiled embarrassedly. He quickly looked at the back of the classroom and saw that his three roommates were sitting very far apart. Obviously, they did not manage to get a seat. Therefore, he was about to go to another classroom to get a chair.
Suddenly, a guy sitting in the first row suddenly stood up. He packed up the textbooks and pen case on the table and made a gesture.
"Boss, please sit here."
"No, it's fine. I'll go to the classroom next door and get a stool." Lu Zhou didn't know whether to laugh or cry as he declined.
"No, no, no. I'll just go and get a stool. I just want to borrow your notes to read!" the man insisted stubbornly.
Borrowing notes was easy. As long as he returned them on time, he could borrow them as he pleased.
The problem, however, was not with the notes.
But in this situation, Lu Zhou didn't dare to sit in the first row! He already had the debuff of attracting attention. If he were to move his stool, everyone in the classroom would subconsciously stare at him …
This feeling of having a dagger on one's back was really too uncomfortable.
Lu Zhou refused to sit down. He went to the classroom next door and brought a chair back. He sat next to Huang Guangming in the last row.
Curious as they were, these people couldn't possibly turn around to look at him during class, right?
Professor Liu Xiangping looked at him with a smile and didn't say anything.
The bell rang and the class began.
Professor Liu released the PowerPoint and smiled.
"Turn the textbook to the introduction."
While other people were preparing to listen to the lecture, Lu Zhou also opened and began to study the advanced algorithms designed for artificial intelligence.
Without the assistance of the focus capsule, it was not easy to completely understand a book. Fortunately, the level of the main subjects not only strengthened the ability to apply knowledge, but it also improved the ability to learn knowledge.
So far, he had already read half of this textbook that was as thick as a dictionary.
Even so, when he checked the core code of Xiao Ai last night, he still found out that there were many things in it that he could not understand with his current level of knowledge.
At the same time, Professor Liu continued to lecture on stage.
"… The requirements for equations in middle school mathematics are usually to find the relationship between the known and unknown numbers in the research problem. Then, list the equations that contain one or more unknowns, and then solve them.
"In actual work, we often encounter some problems with characteristics that are completely different from the above equations. For example, the movement and change of matter under certain conditions, we need to find the law of its movement and change. For example, a rocket is propelled by an engine in space, we need to find the trajectory of its flight. This requires us to find a formal function analytic formula with existing data, rather than using the function given by the "problem" to calculate specific unknowns.
"Ordinary differential equations are a very useful 'tool' subject. It has important applications in many fields, from automatic mechanical control to ballistic calculation of rockets and missiles, to the stability of chemical reactions, etc."
Professor Liu smiled and said, "Therefore, you applied mathematics students should pay attention to this class. If you don't do well in this class, don't tell people that you graduated from the University of Jin Ling, and don't tell them that I taught you. It's too embarrassing! "
This Professor Liu was also an interesting person. His lectures were not boring. He could explain complicated things in an easy-to-understand manner, and the easy-to-understand things could be expanded into deeper areas.
Even Brother Guang Ming, who never paid attention, put down his phone and meticulously stared at the PowerPoint on the screen. From time to time, he would jot down notes in his notebook.
The progress of university courses was very fast, but Professor Liu was no exception. He lectured faster than flipping the pages of a book.
It was impossible to take notes in class. It was already very good to be able to keep up with the speed of the teacher's lecture. The students kept taking pictures with their phones. It was like a technology company's press conference.
Half of the class passed by. The first chapter of differential equations and their basic definitions and geometric explanations were finished. Then, it was the second chapter, the first section of the elementary integral method – Appropriate Equations.
The difficulty instantly increased.
A bunch of new knowledge points were thrown at them. Many students who had not previewed this chapter were complaining. Even though the professor on stage had the ability to simplify complicated teaching techniques, some of the elementary students felt that it was a bit difficult.
"The knowledge points are almost done. I'm sure you guys have previewed it yourself. Let's practice with this problem." Professor Liu smiled and pressed on the laser pointer. He flipped to the next page of the PowerPoint, "You guys calculate this problem. If anyone knows how to solve it, you can come up and write on the blackboard."
[Determine if it is an appropriate equation and find the solution to the equation.]
Lu Zhou glanced at the question on the PowerPoint. He saw that it was not difficult, so he did not care and continued to read his book.
However, the other students were not as relaxed as him.
They were new to this class. Many people had only previewed the first chapter. They had not previewed the second chapter yet. They looked at the appropriate equations and were confused. Only the genius students picked up their pens and started calculating on the draft paper.
Two minutes passed and the classroom was silent.
"Why is no one raising their hand?" Professor Liu smiled and joked, "You guys are all students who can get into a university. You can't all be guaranteed, right?"
The guy from class two who was sitting in the first row smiled and weakly said what everyone was thinking, "That big shot didn't even raise his hand, how would we dare to raise our hand?"
Many people in the front row nodded in agreement.
There were still people who could calculate it, but no one dared to raise their hand.
Professor Liu pretended not to hear it. He smiled and said, "No one is going to answer? Looks like I have to give them a prize. Okay then! Whoever can solve this problem will get an extra 10 points from their usual score. I'll note it down. "
Lu Zhou, who was still studying machine learning, suddenly raised his hand. The speed at which he raised his hand shocked Huang Guangming, who was still calculating.
However, Lu Zhou did not look at him. Instead, he stared at the PowerPoint.
Ten o 'clock in the morning!
This is a ridiculously simple question, it's free!
However, Professor Liu did not give him any face. He smiled at him and said, "Put your hand down. You don't get a 10 points. You can raise your hand if you want, but I won't call your name. If you can get a full score at the end of the semester, I'll give you all my points. If you're one point short, I won't get a single point! "
Lu Zhou: "…"
The whole class took a deep breath.
No wonder he's a genius student. Is he going to get a full score?
Lu Zhou smiled awkwardly and put down his hand.
