Your Distance

After Bo Changyi's birthday, Ting Shuang started to worry about the exam in early August. This anxiety has been going on for a month, and the anxiety gets worse as we get closer to the exam. The anxiety of the previous exam and the major event of Bai Changyi's birthday were blocked in front. When the event was over, the anxiety directly resolved.

Anxiety is caused by stress.

Some people will work harder to review because of the test pressure, but some people will become more and more passionate about everything that has nothing to do with study because of the test pressure.

Court cream is the latter.

His first exam had nearly 3,000 pages of courseware to review. It is gratifying that when he was three days before the exam, he had read the last page of courseware, but it was even more sad to read the last At one page, he had forgotten more than two thousand pages.

He came out of the study with anger and walked the dog in panic, watching animations, playing games, and smoking.

When Bo Changyi returned in the afternoon, there was a smell of smoke in his home.

Ting Shuang was copying a comic on the sofa with a pencil and a draft book.

"Ting, how much cigarette did you smoke?" Bo Changyi approached and saw the ashtray on the coffee table full of cigarette butts and ashes.

Ting Shuang stunned the exhaust gas: "The smoke alarms are all sounded."

"Then?" Bo Changyi picked up the cigarette case on the coffee table, and at a glance, it was empty.

Court Frost: "Then I turned off the smoke alarm."

Bai Changyi walked behind him and watched him draw with an extremely irritable attitude: "Can't he keep reviewing?"

"Not only? I can't go on in my life." Ting Shuang poked at the book with a pencil and said angrily, "I won't be a human."

Bai Changyi leaned down and kissed his ear, chuckling: "What do you do? Be a rabbit?"

Ting Shuang turned his head and was very upset: "I'm all like this, you still tease me."

"Okay, don't tease you." Bo Changyi sat next to Ting Shuang. "Let's solve the problem. What are you doing now?"

Ting Shuang described the 3,000-page courseware tragic incident and said, "I feel like I'm stuffed in my head. I really can't keep stuff in it, but if you want me to think about what's in my head, I will I can't remember anything. "

"Can't remember anything?" Bo Changyi emphasized the word "what".

"... Um." Ting Shuang nodded.

Park Changyi casually asked a concept.

Ting Shuang thought about it, and quickly answered.

"Happy?" He never thought he could answer, "I thought I didn't remember anything."

Bai Changyi said, "You don't even ask a question, how can there be an answer?"

"It was like this ..." Ting Shuang thought for a moment. "It seems to be, every time I review my own stuffy head, it's quite vain, but I went to the examination room to answer specific questions, and it's okay. Hey, boss Bo, you said Is it that I am too high? Just the kind of imagination, I actually know a lot, but I think I do n’t know. "

Bai Changyi: "You call this a system of knowledge."

Ting Shuang: "... Oh."

Bai Changyi took the draft of Tingshuang and drew the knowledge tree: "You have to figure out where in the knowledge system you are learning now. At the same time, you have to know which position is missing and which position you have Mastered, to what extent. "

As he painted, he talked to Ting Shuang, and soon a leafy tree of knowledge appeared on the paper.

Some end leaves of this knowledge tree can no longer continue to extend downward, that is, the current knowledge boundary of human beings.

"You see, this is my system of knowledge. You can also try to do this, so you know what you have, what you lack, and you won't remember anything."

"Well, I try ..." Ting Shuang nodded, holding the picture of Bai Changyi as a reference, and drew his knowledge tree.

He painted and wiped, wiped and painted, hesitantly, it took a long time to draw a knowledge tree with only four solitary branches.

He looked at his bare tree of knowledge, and then looked at Bai Changyi's amazingly thriving knowledge tree. He looked back and forth so many times, and finally became desperate.

"... I don't really know what my knowledge system should look like." Ting Shuang looked grayed out, "... I just seem to take the exam."

Park Chang thought for a while, and wrote on the paper different research directions in twenty robot fields such as "otionandathnng" and "learningandadativesystems": "Are you interested?"

Ting Shuang looked down one line at a time, seeing that none of the last line liked it, he shook his head in frustration.

Bai Changyi pondered for a while, took people over, kissed his forehead, and said, "Let's go out and play."

"Ah?" Ting Shuang thought he heard wrong, "Go out to play? Now?"

"Well," said Bo Changyi, "now."

"You're a professor ..." Ting Shuang couldn't respond, "how could anyone take the lead in going out to play during the exam period ..."

Bo Changyi rubbed a hand of Tingshuang's hair: "You don't like it, what kind of professor am I?"
