Early in the morning, Liu Fei hurried to the mathematics school district with his textbooks.

Even if you choose a school in the first two years of freshness, you still have to take big classes most of the time, after all, you can only go deep in different directions when the basic theory is solid.

Liu Fei was exposed to a large number of basic mathematical theories in high school, and he also recognized a relative at Hangzhou Normal University, which can be regarded as the most abundant knowledge accumulation in various disciplines.

Coupled with the bonus of the book of mathematics, it is natural to choose to get the math first.

In fact, there are about 10 to 15 students in each class of the so-called "laws of nature".

There are not many advanced things in theoretical learning, so students naturally don't want to enjoy the beauty of one-on-one teaching by masters.

Of course, the so-called less so-high is limited to the 'laws of nature'.

For most scholars, the school of mathematics is the most demanding of all disciplines, and without a solid foundation, it is almost impossible to make a difference in the following branches.

Therefore, the boring and wide-ranging basic theories in the early stage often make many people worry about losing their hair.

Liu Fei walked into the classroom and found that it was indeed the case.

In addition to the two familiar faces of Anxin and Cantor Tesla, the rest are of different ages, and some must be new students this year.

But the three with vicissitudes written all over their faces in the corner...... Liu Fei coughed lightly, I am afraid that it is similar to his father, right?

But who knows?

I'm proud of studying mathematics, I'm a national provincial hairspray, maybe the three brothers are about the same age as him.

As soon as Liu Fei came in, he instantly attracted the attention of many people.

Seeing Liu Fei nodding lightly, he continued to brush the questions.

Cantor Tesla rolled his eyes as usual, but this time he was smart enough not to talk to Liu Fei, lest the bastard talk about the Crown of Truth again.

Most of the others responded with a kind smile or curious glance at Liu Fei.

After all, Liu Fei is an old fritter who has been in the society for many years, and it doesn't matter who sends a smiling face first, even Cantor Tesla is no exception.

A little cold scene in the classroom quickly passed, and everyone found that Liu Fei, the so-called madman, was actually very easy to contact, and there was no swarf, and there was even a little bit of comics.

Coupled with the sense of identity brought by the mathematical school, the atmosphere soon became lively.

Everyone, you say a word to me, it is nothing more than why Liu Fei chose the eight disciplines, as well as the gossip about various things before.

Liu Fei smiled, anyway, if he can blow it, if he can't blow it, he will be embarrassed to blow it, as long as he doesn't say who knows the truth or falsehood.

The geniuses in the class who didn't know the truth were stunned by Liu Fei, and they all admired it very much, and they really thought that Liu Fei was the kind of good student with a tough personality, noble morals, and integrity.

The peace of mind that brushed the question in the back rolled his eyes.

Cantor Tesla, the math genius of the academic hegemon, has instead become a little transparent in the classroom.

He was still young and had always been smooth sailing, he was a genius who was held in the palm of his hands by his teachers in high school, and his classmates around him all regarded him as an idol and role model.

Now that it's the 'law of nature', whoever you take out is a leader in one side, and who will convince who without the strength to absolutely crush it?

Cantor Tesla, who is proud and not good at expressing himself, falls into a deep inferiority complex.

Could it be that he is not as good as him in exams, and even his popularity is not as good as him?

"Morning, classmates. ”

At this moment, a spectacled instructor walked in through the door.

He is Mr. Telles, a master scholar and an expert in the school of mathematics-mathematical analysis.

Mathematical analysis, also known as advanced calculus, is the oldest and most fundamental branch of analytics.

The analytical branch in mathematics is the branch of mathematics that specializes in the study of real and complex numbers and their functions. Its development began with calculus and expanded to various properties such as the continuity, differentiability, and integrability of functions.

In particular, it is of great help to the study of the physical world, the study and discovery of the laws of nature.

Liu Fei focused on self-study of this part of the content in high school, and there is basically no problem with the basic knowledge, but it is of great significance to further understand the subject after the teacher's systematic explanation.

Monsieur Telles, a French man with a natural romantic temperament, looks more like a model than a scholar in a well-fitting gray suit with a delicate tulip brooch pinned to his right pocket.

"Ladies and gentlemen, it is an honour to meet with you. Before I get started, I'd like to start with a question, what is math?

"Mathematics is a mental game with certain rules. Cantor Tesla couldn't wait to get up and answer the questions.

Telles shrugged: "This is something that only someone with absolute confidence in mathematics can say." ”

"A description of the structure (the number of things that exists) and the relationships (there are changes), and the methods and processes for verifying (the structure and relationships). After thinking for a while, he replied.

Telles smiled: "Reasonable, but I don't think it's accurate enough, is there any other answer? Mr. Liu Fei?"

Liu Fei thought for a long time, this question was out of the program, and after a while, he replied: "Mathematics...... Isn't it math?"

Cantor Tesla sneered: "A word of nonsense. ”

Liu Fei hehe: "Then tell me what mathematics should look like?"

Cantor Tesla stammered, what is the math like? How can this be explained?

Telles clapped his hands and laughed: "Everyone is right, what is mathematics? I believe everyone has a different understanding, many students are still very confused about mathematics in the initial learning stage, and some even use it as a tool for advanced scholars." ”

"In fact, I would say that mathematics is a summary and verification of the eternal laws of nature. For example, one might ask why one should prove facts that are clearly true in nature when learning mathematical analysis. I can answer you that some things that are taken for granted are often not so natural. ”

"For example, do parallel lines never intersect, or do they intersect at infinity, or are they infinitely far away?"

"People who have not studied mathematics or have no deep understanding of mathematics will answer, parallel and parallel, so it is natural that they should never intersect?

But as a scholar of mathematics, he could not think so, so Euclid wrote the fifth hypothesis, the fifth hypothesis that has been debated for 2,000 years: a point beyond a straight line, there is only one straight line parallel to the known straight line. ”

Telles paused slightly: "Is there a problem with this sentence?"

Some students nodded, while others shook their heads.

Telles chuckled: "I'm afraid this debate will continue until the problem is resolved." Legend has it that the defunct school of differential geometry once made a contrary assumption about the Fifth Apostulate, but with the attack of the ghosts, its research results dissipated, and the school never really rose again, and the Fifth Apostulate became a topic of continuous debate. ”

"Two lines, can they always be parallel!"
