China, 2015.

The difficulty of the astronomy course should also be clear, right? First of all, there is physics at the professional level, then mathematics after mathematics and economic mathematics, English is also at the index level, and there are a bunch of computer languages dedicated to astronomy, and then there are basic courses in all directions based on the former, the difficulty and capacity of which can be imagined.

If you don't have a deep hobby and research on astronomy, and you have a strong idea of engaging in research, try not to come to the Department of Astronomy, which is a hard way to look at directly.

People who are engaged in astronomy have such a remarkable feature, that is, the work and rest time is basically completely opposite to Beijing time. WHETHER IT'S RSD AND MODIFIED GRARITY, OR ACCRETION DISKS, ONLY WHEN YOU PASS BY THEIR DORM ROOM IN THE MIDDLE OF THE NIGHT, YOU WILL ALWAYS FIND THE LIGHTS ON AND THE CRACKLING SOUND OF KEYSTROKES. Their names are written in romanization and hung on the sign at the door, and it is difficult for many people to remember their names except for the students who work with them. They are so familiar with each other, and they are so strange; I will only greet you politely when we meet. Near-reversed schedules are all too common in the cosmology group; The main scientific work is something that traditional astronomers would never have anticipated, but the working hours remain in the same vein as those of their ancestors (born at sunset, rising and resting). As a result, the Department of Astronomy is rich in academic tyrants, which is also very normal, and those who can get this far are enough to be bullish. The Department of Astronomy of the School of Physics of Peking University, such as Mi Di, Hao Qiuyan, Haidar and many others, can be regarded as this level.

It focuses on the following five research areas:

I. Cosmology and Galaxy Physics

2. Active galactic nuclei and high-energy astrophysics

III. Interstellar medium physics, stars and planetary systems

4. Particle objects

5. Celestial technology and its application

I can finally give myself a vacation, and in the days of my continuous study, I live like a swim.

Outside the Xizhi Gate in Beijing.

The rhythmic tapping of fingers on the table top, rattling is enough to make a person break inside.

Ashley took a sip of coffee: "Midi."

She didn't say anything, she leaned sideways, expressing dissatisfaction. Midi turned her head, and Ashley waited. Probably on purpose, he turned his gaze back to the spherical glassware on the table. Strings of blisters of different sizes float from the base, rhythmically and regularly, and they do a slow cycle.

"I'm almost graduating."

"I'm almost graduating."

It's brief, and it's awkward. The music sounds very pleasant, and with the soft lighting in the café, it seems to come into contact with a phantom, a fantasy world. At a certain point, your perception will be fleeting, leaving only traces of ups and downs in your mind.

Ashley began to take the initiative: "In the past four years, you have always been untalkative, are you avoiding me?" Or is there another reason? ”

Midi explained: "In the early years, I was very communicative, but gradually it became like this, and I can't tell the reason, I feel that my mentality has become old? At my age, it shouldn't be like this; Before the stage of seeing life thoroughly, it should be spent on studying. After taking a sip of coffee, he continued: "The vicissitudes of life in the eyes are not applicable to the measurement of age, but should be mature." ”

Ashley couldn't hide it in her voice: "This is very bad, and there will be obstacles to integrating into society in the future, which is called aging before aging." looked at him with concern: "Look at you are tired of studying, you have gray hair on your sideburns." ”

In a way, Ashley is not excluded, and the East and West have merged a lot. China's traditional ideas have a deep influence on itself, and if you can't use Chinese ideas to influence the West, it will produce extremely fierce confrontation; To embrace the world with an open mind, China must be tolerant, acceptable, and persistent.

After a brief silence with each other, Ashley: "There is nothing wrong with talking more, and it can also relieve the fatigue of studying."

Mi Di smiled: "Thank you for your concern, I have been working hard in that direction, but it still doesn't work well."

Ashley: "I don't often see you laughing, this kind of indifferent heart gives people a feeling of the afterlife. If you want to dig out a few words from your heart, it is not something that ordinary people can do. Not to mention this, what are your plans after graduation? ”

With the development of higher education in China, the number of college students has increased dramatically, and the employment problem has become prominent. In fact, the phenomenon of employment difficulties is more of a social problem than a real problem. At present, there is a serious imbalance in the knowledge structure and skills of college students trained by colleges and universities, which is also the reason why it is difficult to find employment. There are several ways to graduate from the Department of Astronomy, 1. Chinese Academy of Sciences, 2. National Defense Research Institute, 3. Space Agency, 4. Postdoctoral studies, 5. Study abroad, etc.

Midi: "Recently, everyone has been thinking about where to go, and because they are at different stages, their choices are different. Xia Yongxu decided to continue his postdoctoral studies, Fu Yushu went to the Beijing Astronomical Observatory, and Hao Qiuyan and I went to the Wenchang Satellite Launch Center. ”

Ashley had some questions: "Is it bad to go to the space agency?"

Mi Di: "I just graduated, I don't have any experience, the space agency is an administrative unit, and it's unlikely, so it's better to go to the front line to exercise."

Ashley: "It always feels like you're special."

Midi exclaimed, "I'm an alien. It's not easy, you can see that. ”

Ashley: "How is that possible?" You have an inner temperament, the most beautiful thing about youth, there are infinite possibilities, unlimited future. Those songs that once floated on campus touched how many young hearts! Looking back, sometimes even, tears even rained down. The sound of tapping on the keyboard, the words tapping into the almost lonely heart; Our keyboard has the feeling of an afterlife, which is a real feeling. ”

Mi Di smiled: "With such emotion, we don't have a retro heart, but we are all talking, telling about the past that will never return." We're all trying to find our way faster, but we're getting ourselves lost in all sorts of things. We talked a lot, and it was necessary to recognize ourselves; I don't want to go around the bush with you, I guessed your true intentions. ”

"What intentions?"

"I'm not a man!"

Ashley was a little disgusted: "Nonsense, how could I say that kind of thing?"

Mi Di smiled 'hehe': "I really don't have so much pride, unlike the Northeast gentlemen."

"You're a very thoughtful person."

"Oh, it's still a woman."

Ashley was really anxious, but she still held back: "Why don't you talk well, there are many kinds of men."

Taking a sip of coffee, Mi Di lowered his tone: "I belong to that category?"

Ashley is immersed in spontaneous feelings: "You are very disciplined, very respectful of women, and very studious, upward spirit."

"Oh, you make me drift a little. Look at that tree on the street, it never tries anything, just stands there, fresh and beautiful. I'm ordinary, really, walking on the streets of Beijing, unrecognizable in the crowd. Returning to our study life, it's okay to say that I'm decent, it's okay to say I'm a top student, this is a fact, I'm a little too narcissistic! ”

"How is that possible, very much in the spirit of the Americans, because you did it. I usually look at you very stupid, but there is a positive energy in your bones; Also the most charming place, I like men like you. ”

It is also expected to cut to the point, but we should also learn to understand. "I really don't want you to praise me, my brain needs to turn a few more times, give me a time to think and precipitate, otherwise I can't digest it."

Ashley was very direct: "If you go to the United States, my family will support you, and there will be more development than in China."

Ashley is from a wealthy family, and everyone in this circle knows it; Studying abroad is a pretty good choice, and many people have such dreams.

"I don't want to leave China."

"I can marry in China."

This is something that Mi Di never imagined, and her attitude is so firm. Among the more than 10,000 students at Peking University, Ashley can be regarded as a famous school flower and has a family background, who doesn't want to get close to her? Her family has a spacious house in Beijing, but because it is inconvenient to study and lonely, she moved to a school apartment. In the adult world, Mi Di doesn't like to idle some undisciplined clips; He didn't want to leave China, and he didn't like American-style marriage. Not to mention, a journey of a thousand miles, the ending will be miserable, he made a conclusion for himself. In Midi's mind, love cannot exist forever, and marriage is more about trust and support; This is not their choice, sooner or later there will be mistakes, and it is also the reason for inner resistance. However, Ashley has made the substance very clear, and how to make her attitude clear.

Midi put it tactfully: "The more we can understand and the more accurate our guesses are, the easier it will be to avoid many mistakes."

Ashley pondered for a long time, and finally understood the meaning of the expression according to her fine understanding: "We have a gap in concept?"

"It can be understood that way."

“ My God！ Let me give up? ”

"Why be so persistent."

But seeing that Midi sealed her mouth, making Ashley's thinking difficult, she didn't expect it. The surrounding environment is also static, and whoever wants to concentrate on getting something must have traveled three thousand miles. In such a story, no one makes mistakes or mistakes at all, and some things are mainly viewed from whose point of view. The more you want to get something, the more you can't get it, and there are really many things that don't fulfill people's wishes. Midi's refusal caused her to have an unexpected mental impact, and after slow adjustment, she had to turn to studying.

Ashley: "Don't talk about it", but she still feels a lot of pain inside; When people are attentive, suddenly the goal in front of them is gone, what kind of loss will it be! Calm down for a moment, "Are you done with your paper?" ”

"I'm almost done, and the title is 'Astrophysics and Modern Cosmology.'"

"Mine is "A Study on the Ultraviolet and Infrared Observation Characteristics of Stars and Dust in Neighboring Galaxies."

"Oh, yes, in line with your field of study."

"How can I compare with you, but I have been a little curious since I was a child; My parents wanted me to study acting at the Rudolf Steiner School of Theatre, but they respected my opinion. You know, there are good astronomical schools in the United States, so why come to China? Why study such a subject? My personality is sometimes stubborn, and before I went abroad, I had a special yearning for China. ”

Midi: "Now, is it still the same idea as before?"

Ashley nodded: "Well, China is a very sacred country, and the customs here make people nostalgic."

Midi: "By the way, some people say you look a lot like your country's movie star Jennifer Aniston. I've seen her pictures and it's really kind of similar. ”

The mention of Aniston made Ashley feel a lot more comfortable, brushed her long hair with her hands, and stood up to refill the coffee in the cup. I came to the window with a coffee and looked at the scattered pedestrians and cars outside the window, but my heart was sincerely melancholy and lost. It's hard to explain this kind of thing, and there will always be so many accidents. In other words, accidents are also a kind of regret, and regrets are also a kind of beauty.

Turning around: "This is the most memorable conversation of my life, and I will always remember this day."

Mi Di was also relaxed: "Graduation is imminent, and there are many foreign students in our department; Due to my studies, I haven't had a good feel for Beijing during my years in China. With more than a month to go after graduation, I would like to take this opportunity to organize a nostalgic tour of the student union to visit the historical monuments of Beijing, and also let our figure stay together permanently. ”

"I couldn't agree more."

"Let Hao Qiuyan plan the route, it's not too early, let's go back."

At night, the streets of Beijing are bustling with people, and people are relieving their fatigue after a day's work at this moment, feeling the hustle and bustle. They came out of the café, hailed a taxi, and returned to the Peking University student apartment.
