After Bai Changyi's birthday, Ting Shuang began to worry about the exam in early August. This anxiety has been going on for a month, and the closer the test anxiety is, the more serious it is. The anxiety of the previous exam and the big event of Bai Changyi's birthday stood in the way. When the big event was over, the anxiety directly burst.
Anxiety is caused by stress.
Some people will study harder and harder because of exam pressure, but some people will love everything that has nothing to do with study because of exam pressure.
Ting Shuang is the latter.
There are nearly 3,000 pages of courseware to review for his first exam. It is gratifying that he finished the last page of courseware three days before the exam. At one page, he had forgotten the first two thousand pages.
He came out of the study in desperation, and in a panic, he played with his dog, watched animation, played games, and smoked cigarettes.
When Bai Changyi came back in the afternoon, the house smelled of smoke.
Ting Shuang is copying a page of comics on the sofa with a pencil and a sketchbook.
"Ting, how many cigarettes have you smoked?" Bai Changyi approached and saw that the ashtray on the coffee table was full of cigarette butts and ashes.
Ting Shuang was exhausted: "the smoke alarm went off when I smoked."
"Then?" Bai Changyi picked up the cigarette case on the coffee table and saw that it was empty.
Ting Shuang: "Then I turned off the smoke alarm."
Bai Changyi walked behind him and watched him paint with an extremely irritable attitude: "Can't go on reviewing?"
"More than that? I can't go on with my life." Ting Shuang jabbed the book with a pencil and said angrily, "I'll stop being a human being."
Bai Changyi leaned over and kissed his ear, then smiled softly: "What are you doing? Be a rabbit?"
Ting Shuang turned her head and was very unhappy: "I'm already like this, you still tease me."
"Okay, I won't tease you." Bai Changyi sat next to Ting Shuang, "Let's solve the problem. What's your situation now?"
Ting Shuang described the tragedy of the 3,000-page courseware and said, "I feel like my mind is full, and I really can't keep stuffing in it, but if you ask me to recall what I have in my mind, I will Can't remember anything."
"Can't remember anything?" Bai Changyi emphasized the word "what".
"... Hmm." Ting Shuang nodded.
Bai Changyi asked a concept casually.
Ting Shuang thought about it for a while, and quickly answered.
"Huh?" He didn't think he could answer, "I thought I didn't remember anything."
Bai Changyi said: "You don't even ask questions, how can there be answers?"
"So that's how it is..." Ting Shuang thought for a while, "it seems so, every time I smother my head to review, I'm quite empty, but I go to the exam room to answer specific questions, and it's okay. Hey, Boss Bai, you said, Am I too high in realm? Just like a humble person, I actually know a lot, but I think I don't know."
Bai Changyi: "You have no knowledge system."
Ting Shuang: "... oh."
Bai Changyi took Ting Shuang's draft and drew a knowledge tree: "You have to figure out where the things you are learning are in your knowledge system. At the same time, you must also know which position is missing and which position you have already learned. I have mastered it, to what extent.”
While he was drawing, he was talking to Ting Shuang, and soon a tree of knowledge with lush foliage appeared on the paper.
Some of the end branches and leaves of this knowledge tree can no longer extend further down, and that is the current knowledge boundary of human beings.
"Look, this is my body of knowledge. You can try to do the same, so you know what you have, what you lack, and don't forget everything."
"Well, I'll try it..." Ting Shuang nodded and took the picture of Bai Changyi as a reference to draw his knowledge tree.
He painted and rubbed, rubbed and painted, hesitating, and it took him a long time to draw a tree of knowledge with only four solitary branches.
He looked at his bare tree of knowledge, and then at Bai Changyi's astonishingly prosperous tree of knowledge.
"... I really don't know what my knowledge system should be like." Ting Shuang's whole body looked gray, "... I seem to only be able to take exams."
Bai Chang thought about it, and wrote on the paper twenty different research directions in robotics, such as "otion and ath nng", "learning and adative systems": "Are you interested?"
Ting Shuang looked down line by line and saw that there was no one he liked in the last line, so he could only shake his head in frustration.
Bai Changyi pondered for a while, then brought the person over, kissed his forehead, and said, "Let's go, let's go out to play."
"Ah?" Ting Shuang thought she heard it wrong, "Going out to play? Now?"
"Well." Bai Changyi said, "Now."
"You're a professor..." Ting Shuang couldn't react. "How can you take the lead to go out to play during the exam period..."
Bai Changyi rubbed Ting Shuang's hair: "If you don't like it, why should I be a professor."
