Chapter 213 (2/2)
Cheng Nuo said, of course, their other two roommates.
”Oh, this one.” Yuan Hua said, ”the two of them have come long ago. Now they go to the school store to buy thermos bottles and washbasins. By the way, Cheng Nuo, did you bring these things? If not, I asked them to bring a set back for you. In terms of time, they should have just arrived at the mall
”Bring me one.”
…………
Twenty minutes later
Cheng Nuo's other two roommates, one with a lot of things into the dormitory.
”Sister, I'm so tired with so many things!” A chubby boy with a weight of at least 250 Jin put a lot of things on the ground, and then sat down on the stool, panting.
”All right.” The other is a boy with brown black skin and curly black hair. His bulging biceps shows his strength.
”This school is too big. It takes more than ten minutes to walk to the shopping mall nearest to our dormitory.” The little fat man still complained, ”if I had known, I would not have come to Tsinghua! Taitemaokeng you fat
”All right, all right. Don't talk about it. Since all the people in our dormitory are here, let's get to know each other first. ” Yuan Hua clapped his hands to attract the attention of the other three.”I'll go first.” Yuan Hua was the first to introduce himself, ”Yuan Hua, from eastern Guangdong Province.”
”Zhongjian, from Hutun.” The little fat man took out a bag of potato chips and ate them crunchy, looking at Yuan Hua.
”Cheng Nuo, from Dongshan province.” Cheng Nuo introduces himself with a smile.
Finally, the brown and black boy said, ”I'm from Xinjiang, Uyghur nationality, and my name is Maimaidi naransebast gilnur amqi!”
Cheng Nuo's three people:
Big brother, are you sure, what you said is the name?
”Er That what? Can you say that again? ” Cheng Nuo speaks slowly.
”I know you can't remember. To tell you the truth, my name is long in our Uighurs. Just call me T-Mac. ” McGrady shrugged and laughed.
”Then we'll call you Tracy.” The three agreed.
”Come on, eat the chips, eat the chips.” Zhong Dun, a little fat man, handed the chips to the others.
The other three each grabbed one. When he took the chips back, his hand shook carelessly, and one of them fell to the ground.
The little fat man is stunned. When he wants to throw the potato chips on the ground into the garbage can, he is stopped by Cheng Nuo.
”Why don't you eat it?” Cheng Nuo points to the potato chips in the little fat man's hand and asks.
The little fat man's face was muddled, ”it fell to the ground, dirty ah!”
Cheng Nuo serious, ”who said, potato chips fall on the ground, is dirty.”
”Isn't it?” The little fat man continued to be confused.
Cheng Nuo shook his head, a faint smile, ”then I ask you, the shape of potato chips, is it a curved surface?”
Little fat man's math is still good, otherwise he won't be admitted to Tsinghua University. He nodded, ”yes.”
”Is the ground a plane?” Cheng Nuo continued.
The little fat man continued to nod.
”A curved surface, in contact with a plane, is it a tangent contact?”
”Tangent contact means that two faces actually intersect on one line. The area of a line on the two-dimensional plane is equal to zero. Right? ”
”Is a potato chip dirty on the floor? Dirty, dirty how much, dirty a line, a line area is how much? Equal to zero! So, he's not dirty! ”
”Even if it's upside down or vertically inserted on the ground, it's the same. It only intersects a line with zero area!”
Cheng Nuo shrugged and made the final conclusion, ”so for potato chips, which are curved in shape, no matter how they fall on the ground, they will not be dirty. If you pick it up, you can still eat it. ”
”I call this theorem Tangent edible theorem! ”
The little fat man took the potato chips that fell on the ground and looked at Cheng Nuo.
I don't read much. Don't lie to me!
