After four years of college, you still have to get a graduation certificate, even if the current certificate is of little significance, but this is an explanation of your four years of youth. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoSo I went back to Guangzhou, and Ruomeng went back to Nanjing.

I went back to the dormitory, knowing that I was back, and the fat man had been waiting in the dormitory for a long time. I was given the warmest welcome, and three bad guys rushed up to me and hugged me, and they almost hung on me. After a while, he let go of me.

The fat man punched me and howled loudly: "Yangshu, you tell me honestly, where did you go without seeing anyone for so long?" ”

"I said I was going to serve, do you believe me?" I laughed.

"I don't believe it," the servant shook his head, "you must have gone to the wilderness with Ruomeng, tell me honestly." ”

I smiled and shook my head, took out three special business cards of the dragon group, and gave each of them one.

"Wow, it's too domineering, a golden business card, a five-clawed golden dragon, so handsome, Poplar, you really went to serve in that legendary institution." The fat man screamed exaggeratedly.

"Yes, I don't have many business cards, you can take them well, and you can't show them to others easily. Business cards contain mysterious powers, and if you encounter something evil in general, taking out your business card can deter evil spirits. I said with a smile.

"Good thing, you don't have to be afraid of ghosts in the future." Wang Liang said with a smile.

"You've got your graduation thesis ready, right?" I asked.

"Yes, it's all done, June 10th to 15th is the thesis defense time, Yang Shu, you have to do it as soon as possible." The fat man said, "Poplar, do you want to help?" We'll help you, and we'll get it done in two days. ”

I shook my head and smiled, "If I want your help to get this diploma, then I don't want it at all." I made it myself, which can be regarded as an explanation of four years of youth. ”

"Well, since you said so, then forget it, and we'll be happy to be idle. We are going to work in July, and we have to make the most of this last student time in our lives and have a good time. ”

"Okay, you guys go play, don't worry about me, we'll get together when I get my papers." I said with a smile.

The title of my chosen dissertation was "Mathematical Model Construction for Deep-Sea Sneaking".

For this reason, I went to the library to read a lot of materials, and after I cultivated, all my spiritual attributes have been greatly developed, especially after entering the Tiantai Secret Realm, my thinking ability has been greatly strengthened. Now I basically read a book with ten lines at a glance, a professional book with hundreds of pages, and I finished reading it in ten minutes. I spent two days reading hundreds of professional books, including fluid mechanics, geology, fluid dynamics, cybernetics, informatics, etc. In order to obtain real pressure data and ocean current data, I even flew into the sea and dived more than 2,000 meters.

It took me a week to prepare the knowledge and collect and organize the data, and then another week to write the paper, which was 200 pages long. The day I finished writing my thesis was June 7th, and I had two days to go before I started defending my thesis. I handed over the thesis to the thesis advisor two days in advance, and she was stunned for a while when she read my 200-page paper, and then asked in an incredulous tone for a long time: "Yang Shu, is this your own paper?" ”

I nodded and said, "Professor Liu, don't worry, this is my own paper, including a large amount of raw data in the paper, which is absolutely reliable." ”

"You, a large amount of deep-sea data, collected by yourself?" Professor Liu asked suspiciously.

"Yes, I have a relative in the submarine force, and I went to the deep sea for a month to collect this data." I had to lie, if I said that I dived to a depth of more than 2,000 meters, I guess Professor Liu would rather believe that pigs will go to trees than believe me.

"Oh, that's the case, no wonder I didn't see you some time ago, it turned out that I went to collect data, your scientific spirit of seeking truth from facts is worthy of praise, Yang Shu, you are very good." Professor Liu gave me a thumbs up.

"Professor Liu, you have won the award." I said modestly.

"You're really good, and your dissertation is more valuable than a lot of Ph.D. dissertations." Professor Liu said sincerely, "In this case, you can go back first, and I and a few reviewers will take a look at your paper first." How about your first dissertation defense in two days? ”

"Okay, Professor Liu, then I'll go back first."

I went back to live in my dorm because I knew that I was about to graduate and that the day of separation was coming. As soon as June is over, we will go our separate ways, and the four years of youth blending and four years of friendship with classmates are a beautiful memory worth cherishing in the world. So while there is still time, I want to cherish this friendship with my classmates.

After the thesis was completed, there was nothing to do, every day was to play ball and cards with my classmates, and then I played chess with the fat man. Speaking of playing, it's a bit interesting, our class played a friendly match with our brother class. At first, I didn't go to school, and our class was beaten by 51 to 30, which was 21 points worse than the other party. Later, when I was replaced, the situation immediately reversed. When I hit the fifteenth three-pointer, the opponent collapsed and threw in the towel. Later, when the brother class played a game with our class, it was necessary to indicate that "Yang Shu is not allowed to play", otherwise he would not play.

Now the fat man can't win against me when he plays chess, my brain is now more terrifying than the computer, and it's no wonder that the fat man can win me.

Only playing cards still have to play, playing cards depends on luck, and good luck can get good cards. As long as it's not a pig brain, you can win with a good hand. That's why my classmates love to play cards with me, because only by playing cards can I find confidence in me. I'm happy to be there. When playing cards, two packs of melon seeds or peanuts, two bottles of beer, and playing cards while eating and drinking while bragging are really a beautiful thing in life.

The two days passed quickly, and the time for the thesis defense finally arrived.

I was the first to participate in the defense. I walked into the defense room with a calm face, and the four teachers sat in the assessment seats and looked at me with a smile.

I bowed and said, "Hello four mentors!" ”

The four teachers nodded slightly, "Yang Shu, please take a seat!" ”

I bowed one more time before I did.

One of the professors, surnamed Zhang, asked, "Yang Shu, do you think humans should explore the deep sea?" ”

"I think it's very necessary, first, that the earth is the earth of human beings, and we should have a comprehensive understanding of the earth on which we live, and this comprehensive understanding of course includes the content of the deep sea; Second, with the development of human beings, the land will become more and more insufficient, and the development of the ocean will become inevitable, and perhaps in the future, human beings will need to build cities under the ocean, and our deep-sea exploration will help accelerate the realization of this possibility; Third, it is the need for tourism, human beings have a natural curiosity, and the development of deep-sea tourism is definitely of great economic value; Fourth, it is the need of science itself, the deep sea contains secrets that human beings do not know, and science is developed in the unremitting exploration of the unknown. ”

"Okay, that's a good point, you're a math major, what role do you think mathematics should play in deep-sea exploration, and how will mathematical science itself develop in this exploration?" A professor surnamed Li asked.

I went, and saw that these professors didn't intend to make it easy for me, and they asked questions about things other than papers, maybe my 200-page paper stimulated them, so they planned to add some material to me. Fortunately, I was prepared in advance, and it was not in vain to spend two days reading more than 100 professional books in the library.

"Mathematics is the foundation of all sciences, and any exploration of the material world is inseparable from mathematics, and even the study of theology is inseparable from mathematics, and there are many theologians in the West who are themselves masters of mathematics. So, of course, deep-sea exploration also needs mathematics to escort it. As for what kind of development mathematics can get in this exploration, it is difficult to say, there are two results: first, mathematics has nothing to gain in this scientific activity; Second, mathematics has gained something in this scientific activity, as for what we have gained, we might as well diverge our thinking, maybe we will make a breakthrough in the study of the field under the great pressure of the deep sea, maybe it will also be helpful to topology, it will also be helpful to informatics, and even some branches of mathematics that have long been very mature such as differential manifolds will be helpful, maybe we can find ancient lost civilizations at the bottom of the sea, maybe we can find alien activity bases at the bottom of the sea, and so on, in short, everything is possible, Of course, the science that gains the most may not be mathematics, but physics. "I talked.

"Okay, that's right, Yang Shu, it seems that you have really put in a lot of effort." Professor Liu stroked his palm and smiled.

Next, the professors also asked me a lot of unexpected and even tricky questions, and I answered them one by one, and finally, Professor Liu said: "Yang Shu, you are really very good, your thesis defense has passed, and my graduate student is still missing a place, are you interested?" ”

I shook my head with a smile and said, "Thank you Professor Liu for your kindness, I have already found a job in a central agency, and I don't plan to go to graduate school." ”

Professor Liu looked very disappointed and said regretfully: "Yang Shu, it's really a waste to be a civil servant with your talent, even if it is a central organ, but everyone has their own aspirations, so I can only bless you." ”

I bowed, "Thank you, Professor Liu, for your concern." From these few sentences, it can be seen that Professor Liu is a true scholar, and such a person deserves respect.

I looked at the time when I came out of the defense room, I went, two and a half hours, I heard that the seniors were finished in half an hour, and they actually added so much material to me, fortunately I was smart and erudite, and if I changed others, I would definitely be played to death.

The second one to go in was Wang Liang, I saw that this guy was sweating before he entered the door, no wonder he, two and a half hours, this is completely inconsistent with the experience of his predecessors, it's no wonder that he is not nervous.

The other classmates gathered around me and asked me what was going on and why it had taken so long. I smiled and said, "Don't be nervous, my situation is special, I can't use it as a reference, you should just respond according to what you have prepared, you will definitely be able to pass." ”

It may have been my smile that affected everyone, and their nervous expressions relaxed. Sure enough, Wang Liang came out in half an hour, with a smile on his face, obviously passed, and everyone was completely relieved.

It took three days for all the students in our class to finish the defense, and everyone passed. The fat man proposed a dinner party to celebrate, and everyone agreed.

It's still the old place, the big private room of the Maojia Hotel. may really be facing separation, everyone is more enthusiastic and unrestrained than before, and if they don't usually talk, they also talk about it, and the classmates who usually don't look at each other also hug each other and call each other brothers, and even the classmates who had conflicts in the past are also muddy with a glass of wine and enmity. Everyone's faces were filled with joy and enthusiasm, but they could all feel the faint sadness in each other's hearts.

For me, maybe it's the last time I have dinner with the whole class, so I cherish it extraordinarily, in the past, when others toasted me, I would drink to a certain extent and say that my stomach hurts, but today I didn't, I didn't refuse to come, and I also went to toast each classmate with a glass.

When I saluted Liu Yuhua, a female classmate in our class, she looked at me with a red face and said, "Yang Shu, I regret it, I regret not being bold enough to pursue you, but when I made up my mind, you were already someone else's boyfriend." I really regret it, I know I shouldn't have said these things again at this time, but if I don't say it again, I really won't have a chance to say it in the future. ”

I was stunned, I really didn't know, someone was secretly in love with me, you must know that I was not outstanding before, stunned for a few seconds, I smiled and said: "Yuhua, thank you for your love for me, I wish you to find a good man who can be entrusted with your life in the future." I'll drink this glass of wine first, and you can do whatever you want. ”

"Your smile enchants me, but it doesn't belong to me." Liu Yuhua smiled bitterly and drank the wine.

I didn't know how to comfort her, so I found an excuse to toast someone else's wine. Liu Yuhua was left crying lowly, and the classmates next to her were comforting her.

Hey, I sighed in my heart, I hope she can find a man who is really good to her in the future!

The fat man was half drunk, and he began to be a little unbearable, and said loudly: "Four years of wind and rain in the same class, like that brother and sister deep; Once they went to their own places, where to find their soulmates at the end of the world. ”

This time, many more emotional classmates immediately cried, this dead fat man, what are you doing here, it makes people cry.

The meal lasted nearly four hours, and most of the people were drunk when they left, and they all supported each other when they went back to school.

As I watched my classmates go away, my eyes were a little moist. Goodbye, my classmates! May you all have a wonderful life!

The red dust is over, turn around and only the way!

Digression: Today's company is very busy, and I'm afraid that I won't have time to update, so I got up early in the morning and uploaded the latest chapters.
