The discussion on time and dimension unexpectedly helped Zheng Qing get rid of the boring learning and troubles that had been plagued by these days, and regained a bit of the feeling that he truly belonged to a college student.
He also suddenly understood why the First University eventually became the most concentrated place for advanced wizards in the league.
This clean and simple feeling may never be found again after leaving the school gate.
Thinking that he was about to graduate in less than two months, the young public-paid student couldn't help but feel a little regretful and nervous.
Until the weekend.
Before the evening work meeting.
Several young wizards would discuss issues of dimension and time from time to time from time to time, but with the change of discussion location, the number of people discussed also expanded. In addition to the three male wizards in the 403 dormitory, Zhang Jixin and Jiang Yu also joined.
Perhaps because she is about to graduate in two months, Jiang Yu's current style has become a bit "radical" - just like tonight's class meeting, she did not sit in the first row of the classroom as usual, but drove Xiao Xiao away very naturally and sat next to Zheng Qing.
Poor Dr. Xiao Da, after nearly two years of enrollment, he left his comfort zone for the first time and was forced to sit at the same table with Li Meng, who had raised his eyebrows at him since he was a senior.
The good news is that he is still sitting in the countdown rows, but there is an aisle separated from Zheng Qing's seat.
The bad news is that there are no acquaintances next to him and become a little isolated and helpless.
"Is that okay?"
Zheng Qing ignored the doctor's eyes asking for help, looked at the witch's face, and reminded carefully: "The doctor can't stand Li Meng's... If you put him next to Li Meng, it is equivalent to giving Li Meng a vacation."
"She is a college student and she will continue to go to school alone after all."
Jiang Yu flashed over this topic: "We are going to graduate at the end of June. We can't keep staring at her every day after graduation... Do you know what I thought of when you just talked about the dimension development?"
She quietly turned the topic back.
"What?"
"That simple drawing of the little man." The witch held her cheek with one hand, and the quill pen between her fingers turned lightly, and the feathers pointed to the simple white paper behind the door.
Zheng Qing subconsciously squinted his eyes.
A picture, a painting, a standard two-dimensional environment, a special two-dimensional life.
"...I haven't experienced the real two-dimensional world, and I think it should be many different from our world." The witch's calm voice came from his ears: "But when I looked at the simple drawing of the little man, I couldn't help but think, is a symbol drawn on a plane sounded? Is it a 'three-dimensional' life form?"
"Two-dimensional." Zheng Qing couldn't help but say.
"No, it's three-dimensional."
The witch looked at him with big eyes, and his tone was particularly serious: "In addition to its length and width, its life has its own special 'height' - I mean the length of its sound - according to this logic, does the length of its life depend on the length of its sound? How many dimensions does the paper that accommodates it exists? Similarly, the portraits, door gods, etc. on the walls of the school teaching building, are they two-dimensional or three-dimensional life?"
"Three-dimensional? No, wait, or two-dimensional... It seems that it is not right." Zheng Qing was immediately attracted by this new view. He wanted to analyze it, but found that he was at a loss.
"Wait... According to your idea, what dimensions are our wizards?" Fatty Xin looked at the witch with curiosity.
"have no idea."
Jiang Yu shook his head honestly: "I just took it out to discuss it with you because I didn't know... Do you think that little man with simple drawing knows its attributes?"
"How can a guy who can't even see where his brain is, understand such a profound magic theory?" Even Zhang Jixin was not optimistic about the witch's idea.
The four of them looked at each other and looked at Dr. Xiao on the other side of the aisle.
The doctor obviously hadn't recovered from the unpleasantness of being forced to leave his position. He glanced at his head and pretended not to see the eyes of his companions.
But soon, he couldn't help but turn around and add to the new discussion: "—The dimensions possessed by the wizard still do not have a unified statement. Some people think it is 9+1 dimensions, some people think it is 13 dimensions, and some people think it is 10+1, or 9+2 dimensions, etc. These are based on the different states of the wizard... According to the Thomson model, which has the most widely accepted Thumson's model, the simple drawing of the door does not belong to the standard two-dimensional or three-dimensional life form. We can understand it as the life of the '2+1' dimension. Two-dimensional is its basic attribute, and the extra one dimension is its sound dimension. The three-dimensional world or three-dimensional life we usually accept are just special concepts in magic theory, and there are almost no such individuals in reality."
This is indeed a trick.
"It sounds a bit like the concept of 'rational man'." Zheng Qing thought about it.
"What rational person?"
"Bai Ding's economic concept," the boy explained briefly: "Usually, natural persons have too many variables, which is inconvenient to summarize and study. Therefore, Bai Dings abstracted an individual with only basic characteristics by reducing the variables in natural persons, and constructed theories... To summarize in magical language, it means 'everything can be converged'."
The last six words made this corner quiet for a few seconds.
It was still Fat Xin who broke the silence again.
"What 'Thomson model' you just mentioned," he blinked his little eyes and thought hard: "How do I feel like there have been somewhere?"
"The concept of 'magic cosmology' last semester was discussed," Dr. Xiao said in a faint tone and complained: "Although it is an elective course, and although you have been copying my after-class assignments, you have obtained the credits in the end. You can't have no impression of it!"
"Of course I have an impression! That's it, that's..." The fat wizard blushed.
"In short, three-dimensional space and four-dimensional space are not 'nested' relationships, but 'coexist' states. Just like the world we live in, since two-dimensional and three-dimensional can coexist in one world, there is no reason why four-dimensional or higher dimensions do not exist in this world. It's just that due to cognitive limitations, we cannot perceive other dimensions."
Jiang Yu spoke out to answer this question for the fat wizard. After noticing the eyes of others, she rarely stuck out her tongue and looked embarrassed: "I have only previewed so much... The teacher hasn't talked about it yet."
Zheng Qing quietly breathed a sigh of relief.
Almost showed timidity.
This semester, he and Jiang Yu took the elective magic cosmology together, so when Xiao Xiao complained, he was also trying to recall what he had learned, but he got nothing. He just heard Jiang Yu speak, but he didn't go to read the lecture notes.
