Chapter 12 Uncle Can Also Do Calculus

  The old man shook his fluffy explosive hair and stood aside, saying: "Youngster, if you don't sing well, you'll have to continue accepting punishment."

  Song Jian nodded and thought for a moment before saying: "Then let's have a song that Li Shishi loved the most, 'Youthful Years', I'll sing it for everyone."

  "Huh? Who is Li Shishi? Isn't 'Young Wanderer' sung by Ren Xianqi?"

  "You fool, Li Shishi is indeed the number one beauty of the Song Dynasty. What's with 'youthful roaming', could it be a Song poem?"

  "What is this guy pretending to be?"

  The students below started buzzing with discussion.

  Song Jian did not respond, coughed slightly, and sang clearly: "The sword is like water, the salt of Wu surpasses snow, slender hands break new oranges. The brocade curtain is warm for the first time, the fragrance of beasts is continuous, sitting opposite each other playing the sheng.

  "Whispering, I ask: Where are you going? The city has already struck the third watch, the frost is thick and the horse's hooves are slippery. Why not rest for a while, as there are few people on the road?"

  The poem is a good one, and "Shao Nian You" was written by the great Song Dynasty writer Zhou Bangyan. Although it was a temporary creation inspired by his emotions at the time, the beautiful feelings of love between two people are still overflowing from the words and transcending the paper.

  Song Jian had the good fortune of hearing a female performer in the imperial palace sing this song before; this time, it also has a different flavor.

  The old professor beside him nodded involuntarily, his fingers following the rhythm of Song Jian's voice, and his fluffy white hair swayed back and forth with his big head.

  As soon as the song ended, the old professor raised his hand and applauded, saying: "Good! It seems that you have done a lot of research on Song lyrics. Kid, your singing is really not bad."

  Song Jian smiled slightly, but the students in the classroom disagreed.

  "What is this singing?"

  "I don't understand any of these words."

  "Yes, yes, it's a mess, teacher, this won't pass."

  The rich second generation and official second generation below laughed and made a fuss. In this era, those who study this major are all some ignorant and incompetent rich second generations who come to mix diplomas. They naturally couldn't understand what Song Jian was singing about.

  However, these people did not understand, but one person outside the classroom was extremely shocked.

  Zhou Tong is a third-year student in the School of Journalism, Faculty of Arts, Soochow University. Her first class was her major course, and because she got up late, Zhou Tong rushed to the classroom now.

  At this time, a classic and elegant Song Dynasty poem suddenly came from the classroom next door, "A Youth's Ramblings".

  Zhou Tong was extremely fond of Tang and Song culture and had studied it for a long time. At this moment, when she heard this song "Youth Tour", she suddenly became infatuated.

  "It turns out that Song lyrics are sung like this, and it's really wonderful." After listening to Zhou Tong, she felt her heart racing, and she couldn't help but look around to see who was humming.

  She slightly tilted her head, brushed her bangs with her right hand, and looked towards classroom 203 through the window.

  As he looked up, Zhou Tong's left hand bag suddenly fell to the ground, and on the podium stood the very person he had been searching for in desperation for a month, Song Jian!

  "It turned out that he was also a student at Soochow University," Zhou Tong stood there in a daze, a look of excitement and happiness on his face.

  More than a month ago, at Jinbi Huang, when Zhou Tong was still dating Li Jian from the school basketball team, Li Jian took advantage of a KTV gathering to put drugs in Zhou Tong's drink because he couldn't get her to sleep with him.

  Zhou Tong was dazed and confused as he was led into the women's restroom by Li Jian, just as his innocence was about to be lost, when Song Jian suddenly appeared and saved him.

  After leaving Jin Bi Hui Huang last time, Zhou Tong has been looking for Song Jian to repay him and thank him for saving his life, but it's been more than a month since Zhou Tong hasn't seen Song Jian again.

  Zhou Tong leaned against the windowsill, standing foolishly in the corridor, staring intently at Song Jian on the podium in the classroom.

  The students at the bottom were making a racket. The old professor helplessly said: "Young man, you see, it's not that I won't let you go, but these students are not satisfied."

  "Alright, I'll make a fool of myself again, let's have a song, how about 'Hotel California'?"

  This classic old song is a masterpiece completed by the Eagles in their best state and combination, it's a diamond-level golden song filled with eerie and touching melodies. Just looking at the lyrics, it almost sums up all the sadness and confusion of the 1970s. Even now, rock players can't avoid this English song.

  Song Jian has been in the United States for over a decade and is extremely familiar with English, especially this song, at this moment, he burst into loud singing, fully expressing the confusion and struggle in the song.

  Let's sing a song, and the classroom immediately erupted in applause.

  "Good!"

  "My god, this kid is a singer!"

  "Damn it, this unknown kid has stolen the show today! Look at our class flower, her eyes are wide with wonder!" A fat guy wearing a Rolex muttered discontentedly, his eyes fixed intently on Xia Lin.

  In this class, most of them are boys, and there are only five girls. Xia Lin naturally became the prettiest among these five people. In fact, at this moment, Xia Lin's eyes were wide with wonder because she had never thought that her cousin's driver, Song Jian, could sing English songs, and what's more, he sang extremely well!

  Song Jian nodded and said: "Since everyone is satisfied, then I can go down now."

  The old professor nodded and said: "Well, well, not bad, not bad. Young man, what? Is this your homework? Let me take a look."

  As he spoke, the old professor had already opened the advanced math textbook next to Song Jian and pulled out the homework inside.

  Song Jian rubbed his nose and sighed inwardly, thinking to himself, "Alas, I'm just here to hand in an assignment, why is it so troublesome one wave after another."

  Sure, here is the translation:

  As expected, with just one glance, the old professor was already fuming, his white hair standing on end as if he had been electrocuted.

  "This is your homework! Is this the attitude you have towards learning?! Are you doing exercises or sleepwalking?! Look at your problem-solving process, can you even understand the relationship between calculus and basic arithmetic?!"

  The old man was really furious this time. As a member of the Chinese Academy of Sciences and a leading figure in the mathematical world, he couldn't bear to see his students slack off, let alone himself. Now, looking at the solution process on the homework paper, the old professor felt that Song Jian was ruining mathematics and insulting him.

  The old professor suddenly scolded Song Jian, and the boys in the classroom snickered and gloated. Xia Lin, on the other hand, shrank her head, trembling with fear, afraid that Song Jian would expose herself, which would be too embarrassing.

  Zhou Tong, outside the classroom, was also anxiously biting her delicate lips, worried about Song Jian.

  Song Jian glanced at Xia Lin, seeing the pitiful look in her eyes, Song Jian had to swallow his pride and said: "Teacher, don't be angry, actually... I was trying a new method to solve this problem."

  "A new method? The new method you're talking about is just addition, subtraction, multiplication and division, isn't it!" The old professor shouted angrily, the ruler in his hand ready to strike Song Jian's head at any moment.

  Song Jian sighed in his heart and thought: Since things have come to this point, I might as well be more open-minded.

  Thinking of this, Song Jian's whole body felt a sense of relief, and he no longer concealed his sharpness. He picked up a pink chalk from the lectern and said: "Teacher, I'm actually trying to use a new method to solve this problem. Look at this question..."

  Song Jian said, turning around and writing on the blackboard with a flourish, "Here... actually, according to extreme thinking, zero can be substituted here, so this problem becomes simplified, like this..."

  As he spoke, Song Jian quickly wrote out the solution, and in just one minute, he had already obtained the result, which was extremely accurate. It's worth noting that Song Jian's previous incarnation was a graduate student in chemistry at the University of California, Berkeley, although due to his drug addiction problems, he didn't get his degree or diploma. However, when it came to advanced mathematics at Huaxia University, Song Jian was absolutely proficient.

  Xia Lin's eyes widened in astonishment, staring incredulously at Song Jian on the podium. At this moment, Song Jian was no longer a middle-aged driver uncle, but a young professor with profound knowledge.

  The old professor was also stunned for a moment, then opened his mouth and said: "Hmm, the result is correct, but you're taking a shortcut. In this question, directly substituting zero into the limit is fine, but what if it were a different question?"

  Song Jian picked up the advanced math textbook on the table, flipped through it and said: "Teacher, I think that when learning this course, what's important is not to solve specific math problems, but to grasp the thinking of solving problems! Calculus, derivatives, are themselves used to train students' thinking about problems, to make students master the thinking of limits, rather than letting students rigidly adhere to these complex formulas, which is too rigid. Moreover, the computing power of computers nowadays is much stronger, if you really want to solve math problems, you can completely rely on computers."

  After finishing speaking, Song Jian picked up his advanced math textbook and homework, turned around with a flourish, walked to Xia Lin's position, and sat down.

  The old professor stood on the stage, stunned. At this moment, he suddenly felt that a certain belief he had been pursuing for a long time was shaken by Song Jian's words. The old professor liked those all-powerful formulas because he thought they contained human truth, so those formulas could solve all human problems. But Song Jian's words made the old professor less confident, and he suddenly realized that thinking was more important than methods, and much more important!

  The old professor looked down at his lesson plan in a daze, speechless.

  The students in the classroom couldn't help but discuss it among themselves, for they had never seen a student as arrogant and overbearing as Song Jian, who had actually left an academician speechless.

  It's not that Song Jian has a high level of attainment in mathematics, but rather because of the cultural differences between East and West. Song Jian had been studying in the US for a long time before, receiving Western-style education, so it's natural for him to say something like that.

  Sat down, Song Jian pushed all the high school textbooks and homework to Xia Lin, saying in a low voice: "I'm telling you, Xia Lin, next time if there's something so dangerous again, don't look for me, I'm timid, can't stand the excitement, you know, I've been bad at studying since childhood, seeing teachers makes my whole body tremble."

  Xia Lin tilted her head, a pair of big eyes staring blankly at Song Jian.

  "Hey, Xia Lin, Xia Lin, do you know this handsome guy? Introduce me quickly," said a woman on Xia Lin's right, nudging her shoulder. The woman was dressed very maturely, and although she had light makeup on, it couldn't hide the few red pimples on her cheeks. But what really stood out was that this woman's breasts were truly full.

  "He... He's the driver uncle who came to deliver my homework, Song Jian," Xia Lin turned her head and said in a low voice to the woman, "Not some handsome guy, Du Hong you silly girl stop messing around."

  "Driver uncle? Xia Lin, can all the drivers in your family do calculus?" Du Hong opened his mouth in surprise, and the big bun on his chest shook.

  Xia Lin finally reacted and suddenly turned her head, staring at Song Jian with her small hand grasping his neck, "Quickly say, uncle, how do you know calculus!"
