MTL - My Senpai Knows Magic-Chapter 29 Understand?

blah blah blah!

After the crowd, a piece of apple that Isabella had just picked up with a fork fell to the ground.

With her beautiful eyes wide open, she stared blankly ahead and exclaimed, "Blair!"

"It's him…"

In the crowd, Alice's face also showed a hint of surprise, the second-year magic genius, Blair's theorem, the first author of the mystery of Raus, and his actions at this moment...

All this shows that this junior has enough reasons for her attention.

The sudden situation made Britney stunned in place, but then her complexion changed and she hurriedly said, "Blair..."

She was interrupted by another person as soon as she spoke. Debbie looked at the spoiler in front of her and said angrily, "Who are you!"

"I'm a student of Teacher Britney, my name is Blair." Chen Luo looked at the woman in front of him and said calmly, "Mr. Britney's time is very precious, if it's just a problem of this level, don't bother me. Teacher, I will answer your doubts on her behalf."

The purpose of the academic salon is to communicate among scholars.

Mathematicians gather together to discuss problems and exchange ideas with each other, and it is also common for beginners to ask questions from advanced scholars.

However, the number of great scholars is scarce and their energy is limited, and it is impossible to solve everyone's problems. At this time, their disciples will answer their questions on their behalf.

Or, those disciples felt that some questions were too simple to be worth bothering their teachers.

This young man named Blair is obviously for the second reason.

At this time, everyone present had only one evaluation of him at the moment.

Madness!

So arrogant!

What is "just a problem of this level", doesn't he know that it is a problem of this level that stumped several great scholars at the headquarters of the Mathematical Association in the capital, and stumped all the mathematics researchers in the Nolan Kingdom," Questions of this level", including them, all the people present were unable to answer!

In the back, an old man looked at Chen Luo, frowned slightly, and said, "Which little guy is this, I don't know how high the sky is..."

Calvin looked at Chen Luo with a strange look on his face, and said in a low voice, "Look, maybe this little guy can really create miracles..."

Britney looked at Chen Luo with a hint of worry in her eyes. Chen Luo smiled at her and said, "You sit here and wait for a while, I'll be fine soon."

After he finished speaking, he looked at Debbie and the others and said, "Can you make a move?"

Debbie gave Chen Luo a cold look and gave up an empty table. She doesn't believe that the little-known Britney can solve the problem of the nine bridges in the capital, not to mention her young and outrageous student. This problem has stumped countless mathematicians and even great scholars. Can he match the entire mathematics world with the power of one person?

Chen Luo was already surrounded by people. The issue of the Nine Bridges in the Royal Capital had been spread to Yapo City for some time. Almost everyone present had studied it, but to no avail.

If the answer to the Nine Bridges question can be found here tonight, then it will be the biggest reward for participating in the academic salon tonight.

Although this sounds a bit bizarre, the difficult problems of all the great scholars will be solved by a disciple of a rookie mathematician---but isn't that the charm of mathematics?

The goddess of wisdom is not fair. All mathematics researchers must admit that talent, which seems illusory, is real.

They have exhausted the results they have researched in their lives, maybe it is really not as good as others doing it casually...

Under the starry sky of mathematics, countless geniuses have been born, and they have illuminated the entire night sky with the power of one person.

Chen Luo, who has become the focus of the audience, picked up a quill and drew a strange figure on the paper.

The so-called “Nine Bridges of the Royal Capital” by these scholars and the “Seven Bridges of Königsberg” well known to Chen Luo belong to the problem of one-stroke painting.

The "Seven Bridges of Konigsberg" problem is one of the famous classical mathematical problems in the 18th century.

The problem of seven bridges is described in this way. In a park in Königsberg, there are seven bridges connecting two islands in a river with the river bank. One day, a passerby had a boring idea in his mind, whether Possibly starting from any of the four lands, crossing each bridge exactly once, and returning to the starting point?

Although there are two more bridges than the "Seven Bridges of Königsberg", the problem of the Nine Bridges in the Royal Capital is essentially a one-stroke problem.

The Seven Bridges problem stumped many mathematicians in the 18th century, and it was Euler, one of the greatest mathematicians in history, who finally solved it.

Thinking of Euler, Chen Luo couldn't help thinking of Euler's teacher Bernoulli, and Bernoulli's teacher was called Leibniz.

Euler also had a student named Lagrange, and Lagrange later accepted a disciple called Cauchy -- these names were once the nightmare of Chen Luo University.

Until now, he has not been able to forget the shadows once dominated by these people.

Euler not only solved the seven bridge problem, but also created a new branch of mathematics - graph theory and geometric topology while solving the problem. At the same time, he also summarized and classified such problems and got And proved several more general conclusions about one-stroke painting, which are usually called "Euler's theorem".

Since then, the problem that has plagued countless great mathematicians has become a score-giving problem for the primary school math Olympiad.

Chen Luo has no interest in teaching these people elementary school math Olympiad, but he has to take into account Teacher Britney's face.

Putting away these thoughts, he looked at the graph on the paper again. Although the problem of one-stroke drawing is simple, it involves an important mathematical idea, which abstracts a complex practical problem into a suitable mathematical model. This mathematical idea, It only began to sprout in the eighteenth century. According to the level of mathematics development in this world, it will probably take hundreds or thousands of years to produce such modern mathematical ideas.

Chen Luo pointed to the graph on the paper and said, "The problem of nine bridges can be represented equivalently in this way. We consider each piece of land as a point, and the bridge connecting the two pieces of land is represented by a line, and then we get the graph on the paper. , If you can start from one point and draw this figure with one stroke without repetition, it means that you can start from a piece of land, walk through the nine bridges without repetition, and then return to the starting point.”

A scholar who was closest to Chen Luo had just seen the graphs he drew on the paper. When he was at a loss, he heard his explanation and suddenly realized that he couldn't help saying: "How could this be possible, to solve complex real problems Simplified to geometry...what a brilliant idea!"

The scholars around had also studied the Nine Bridges Problem. They crowded to the table and looked down at Chen Luo's diagram, and immediately realized that this was a simplification of the Nine Bridges Problem.

In a short period of time, most of the people around had put away their contempt for the young man in front of him.

No matter whether he can solve the Nine Bridges problem or not, it is just this subtle thought that will make him win everyone's respect.

This has taken the Nine Bridges issue a big step forward.

Douglas' face was calm, and he couldn't see his emotions. Debbie's face became a little unsightly. He glanced at Chen Luo and said, "You..."

"Don't talk yet." She was just about to speak, but was interrupted by someone next to her, who didn't even look at Debbie, looked at Chen Luo with a look of advice, and said, "Please continue."

Debbie's face flushed, but she didn't dare to say anything. The other party was a famous scholar in Yapo City, and her status was higher than her elders.

Chen Luo nodded slightly to the scholar and continued: "Obviously, except for the starting point and the end point, when someone enters a piece of land from one bridge, he must leave from another bridge, so, except for the starting point and the ending point, every piece of land must be left. The number of bridges connecting land and other land must be even... We call the points connected by odd line segments on this graph an odd point, and the points connected by even line segments are called even points... "

Mrs. Britney stood behind Chen Luo, with a look of surprise on her face, and murmured: "If you want to start from the starting point and finally return to the starting point, you must reach all points and leave all points, so, only All the points are even points, so the problem of nine bridges can only be solved..."

"As Teacher Britney said." Chen Luo turned around, looked at Teacher Britney with a smile, and said, "The problem of the Nine Bridges in the Imperial Capital obviously has a singularity, a land that can only enter and cannot leave. Therefore, There is no one way to start from the starting point and return to the starting point without repeating all the nine bridges..."

"To sum up, there is no solution to the problem of the Nine Bridges in the Imperial Capital."

After Chen Luo finished speaking, he looked at Debbie and the others and asked, "Do you understand?"
