In the blink of an eye, it was December, and the weather gradually began to get colder, and Jian Zhen began to put on a sweater under the orange school uniform in autumn. Three months have passed in high school before I know it, and the main course has gradually become more complicated from simple at the beginning.

Physics class

"Students, today we are going to learn the most important thing in physics........" with funny black curly hair, holding a pair of reading glasses that only when reading textbooks, with a slightly sissy tone, it looks a little offbeat, a little funny, and Jian Zhen's physics teacher.

There was some commotion and even laughter in the classroom, because this seemed to be the opening statement of every teacher.

"Students, don't believe it, what you learn today will be the core of physics, the top priority, and the focus of the exam, but this time the monthly exam will not be examined. Juan Lao couldn't help but take off his reading glasses, made some exaggerated movements with one hand, and then pinched the orchid finger, which looked a little spicy.

Hearing that he didn't take the monthly exam, Jian Zhen also became absent-minded, and he was a monk for a day and hit the clock for a day.

Jian Zhen, who was originally sitting in the first row, began to look at the blackboard in a state of distraction, almost in a state of distraction. Although the monthly exam is coming soon, he is not in the state at all. Often at this time, Jian Zhen said something familiar: "I have a special fall in love with a girl again, she is delicate and moving, so-so, I have a good impression, I will never forget it for a long time at a glance, that leg is long." The chest, flat. The eyes, two. It's from the next class, not the Jiaojiao who was expelled, it's another one, another ..... from the next class."

Usually at this time, the teacher who is not feeling well will ask questions.

"A point in physics, or a ball. What is the difference between the two points in mathematics? Let's talk about ...... "The old man quickly crossed from one group of gaps to the other group of gaps, accompanied by the wave of his hands, and looked left and right to see what he was looking for. The not tall body, coupled with the agile movements, is a little surprising.

"This classmate, could you please tell me what is the shortest between two points in mathematics?"

"Huh?" Jian Zhen, who was originally smiling stupidly, suddenly smiled embarrassedly, and the speed at which he stood up was quite fast, what did he say just now? In desperation, he could only bite the bullet and say, "What? Teacher, you say it again." ”

"What's the shortest between two points?" Elder Juan glanced at Jian Zhen's radiant eyes, and repeated unmindfully.

"The curve between two points is the shortest. ”

Laughing, as Jian Zhen expected, the moment he blurted out, Jian Zhen regretted it, his intestines were almost green, and the shortest straight line between two points was the most basic mathematical knowledge, look at my mouth.

"Don't laugh, this classmate is actually right. As soon as he finished speaking, the old man jumped on the podium and drew two points heavily with chalk on the blackboard.

Jian Zhen laughed dryly, feeling that Juan Lao was sarcastic about himself, because even a dog knew that it would rush straight towards the flesh and bones, and would not run over crookedly...... Eh, it can be regarded as the price of his own distraction, Jian Zhen thought to himself, thinking that he was unlucky.

"Every theory you have in junior high school will be overturned in high school and given new concepts, such as negative number algorithms, such as photosynthesis .......," Juan Lao said murmuringly.

Jian Zhen didn't quite understand what Juan Lao meant, and presumably others thought the same way. After all, no matter how much sophistry you make, you can't deny the fact that the two points are indeed the shortest straight line.

"Because—when you go to work, or go to college, you will slowly discover that the shortest straight line between two points can only be true in the field of mathematics, and in many cases, it is not the shortest straight line.....," Juan Lao continued. It doesn't matter if you don't understand now, because if you want to get from this point to that point, you will always take a long detour, or even turn back to the original point, and take another detour, so that you will zigzag to another point, so in the field of philosophy, between two points is not the shortest straight line, but the shortest curve, of course, we will not discuss this issue here, okay.......!

Jian Zhen slowly sat down with a look of shame on his face. staring at the textbook, I was a little dissatisfied in my heart, feeling humiliated, but I was helpless, knowing that it was my fault, and I didn't want to admit it.

After class, Jian Zhen closed the physics textbook with some irritation, and talked about the particles in physics in the whole class, which was really boring.

"If you don't study hard, what are you thinking about all day long?"

"I miss a woman!" Jian Zhen said, "I fell in love with a girl in the next class!"

"Who? I'll show you. Muryu laughed.

"Nonsense!" Jian Zhen shook his head, he didn't know when he would be able to change this strange problem.

"What's next?"

"Yilong's class, it is estimated that it is about test papers, didn't our test papers be changed for other classes?

"He's lazy. ”

"That's it! I can't bear it, didn't the whole class change the test paper last time, and I changed it while explaining. ”

While Mu Liu and Jian Zhen were talking, Yilong walked in, dropped a test paper, and motioned for the class representative to send it back.

"Wow-" Jian Zhen was in the first row, a bunch of test papers of his own group, and the name of the corrector in the next class would be written in the upper left corner of the test paper, so as to facilitate the responsibility to check and correct mistakes in the future. In the test paper, Jian Zhen saw the familiar name, and said a sentence inexplicably in his heart, it can't be so coincidental, right? The fact is also so coincidental, the name of the girl that Jian Zhen "fancies" happens to be in the upper left corner of Jian Zhen's test paper, which means that his test paper was corrected by the other party.

Jian Zhen's heart was beating wildly, and he gestured to Muliu with his eyes, but fortunately, Muliu watched the test paper come down, and he went back in a little anxious.

"Maba!" Jian Zhen wanted to cry when he saw his unrecognizable test paper that had been revised.

"Forget it, I won't like her in the future!

So cheap!
