Fall in love with the ex Bai Yueguang

Xie Li's time suddenly became valuable, more valuable than he thought.

Shen Zhichuan was like a urging Hades, calling him every day to inquire about his progress, and he didn't even send emails in order to be straightforward.

Under Shen Zhichuan's suggestion, Xie Li and Cheng Guang made a demo that simulated the process of the Large Magellanic Cloud being gradually swallowed by the Milky Way.

The new algorithm solves the problem of excessive dissipation or accumulation of air clusters in irregular nebulae.

Even their demo provides new evidence for a controversial topic in the current academic circle.

For a long time, there have been different opinions in the academic community on whether the star bridge material between the Magellanic Cloud and the Milky Way came from the Large Magellanic Cloud or the Small Magellanic Cloud.

Judging from the pictures observed by scientists, it seems to come from the Large Magellanic Cloud.However, when the composition of the Starbridge matter was analyzed by ultraviolet rays under the Hubble Telescope, some scholars believed that these matters all came from the Small Magellanic Cloud.

The model of Xie Li and Cheng Guang shows that if the Large Magellanic Cloud gradually approaches the Milky Way, due to the influence of different gravitational forces and three-dimensional fiber structures, the size and brightness of the star bridge, as well as the influence of tides on the spiral arms near the Milky Way, will be farther away. Far beyond what humans can observe from the earth now.

In other words, what is approaching the Milky Way and being swallowed up by the Milky Way is the Small Magellanic Cloud.

On the screen, the huge nebula glowed with a light purple red, which was the intense light emitted by hydrogen ions and nitrogen ions after matter rotated, collided and exploded under the action of gravity.

The gas shell of the nebula gradually shrinks at a speed visible to the naked eye, forming a bright arch bridge, connecting it with the Milky Way.

The huge Milky Way is like an insatiable predator, constantly plundering the gas of the companion galaxy.

If you observe this process under an infrared telescope, you will find that the "sucked" nebula will continue to get colder, and the lower and lower temperatures will accelerate the death of the star.

Xie Li and Cheng Guang gathered around the computer, staring at the screen.

The birth and death of galaxies that lasted for hundreds of thousands of years was condensed on a small screen.

The descendants of human beings will witness this prediction from their ancestors in hundreds of thousands of years.

If there were still humans at that time.

When the jet belt resumed its beautiful jet trajectory again, and when the last ray of red light went out, Cheng Guang couldn't help but let out a long breath.

"It feels so much like Genesis."

In the evening, Xie Li continued to fix the code of the demo in the office, and when he fixed a few small bugs, he remembered what Cheng Guang said for no reason.

Suppose the universe is a giant simulation.All the stars, planets, and even the animals on the earth are composed of more or less parameters. Does it mean that fate is also doomed?

So what does his future look like?Going abroad or not going abroad, which one is the set path?Is he and Tan Ke meeting by program, or is it a bug left by a careless programmer?

For the first time, Xie Li had the idea of ​​"why".

If the Creator really exists, why does his innate parameter have no father and no mother, and why does he get the result of his poor English in the calculation path.

The brain belongs to him, and the body also belongs to him. Why can't he change his original parameters?

Why can't he rebuild the algorithm for his future?

He also wants to stand at the pinnacle of science, at the forefront of human civilization, and explore the future.

This ambition comes and goes quickly.

Once he goes abroad, he and Tan Ke will become a foreign relationship.

That day, Tan Ke specially showed him the old photo album, just to tell him how good it is outside and encourage him to go out.

If he said to go, Tan Ke would definitely not stop him.

But this relationship has just started. Can they really withstand the test of a foreign country?

Xie Li's article and model were revised by Shen Zhichuan, and immediately sent out, and submitted to the International Astrophysics Academic Conference in September, and Xie Li's demo was also sent to Shen Zhichuan. I have already contacted Princeton, which specializes in cosmological evolution. direction of the team.

Xie Li became the corresponding author and first author alone, and Cheng Guang became the second author.

When the two came out of Shen Zhichuan's office, Cheng Guang clasped his hands, and only when he walked out of the office building did he say with emotion: "Li, we two are so lucky."

Xie Li understood what he meant.

Generally, tutors have to have a corresponding author, and some are even more ambitious, and they take the first author, and completely take the students' achievements as their own.

But Shen Zhichuan only put himself in the third position.

In his own words, he made almost no substantive contribution to Xie Li's article, and posting three works is purely to support him.

All of a sudden, all the things in hand were handed over, and a lot of time was freed up.

When the people in the neighboring offices heard that Xie Li and Cheng Guang had submitted papers, they rushed over to inquire.Xie Li didn't dare to talk nonsense about things that didn't come to fruition for the time being, so he could only deal with it.

Really tired of dealing with it, he just hugged the bag and urinated.

Tang Wanwan had just been discharged from the hospital, so he didn't come to school and was temporarily living in his own home.

Xie Li simply bought some fruit and ran to see her, only to catch up with Tang Wanwan who was moving.

The house was full of chickens and dogs, and people came in and out.

Tang Wanwan squeezed her junior brother's face, and pointed to the broken cardboard box next to him: "Sit down by yourself, I'm busy, I can't care about you anymore."

The wedding photos were taken off the wall and thrown in the corner.

Tang Wanwan squatted on the ground to pack the solar system model she made when she was in college, and stuffed the plastic foam into the gaps between the stars bit by bit, then wrapped it in plastic film, and wrapped it with tape.

Xie Li handed over the scissors: "Senior sister, are you really divorced?"

Tang Wanwan took the scissors, quickly cut off the tape, squeezed out the air bubbles, and without raising his head, he replied, "Yeah, I'm not in a rush to move. I rented a house next to the school, and I'll move in later." Please eat."

"So fast?" Xie Li asked stupidly.

Tang Wanwan put the model into the box, straightened up, looked at her former home, and said evasively: "Yes, there are few people there for divorce, and there is no need to line up. Pass the materials over, and they will ask a few questions, and then Zhang Zi Once the cover is clicked, it will be over in half an hour at most." She added with emotion at the end, "It's much easier than getting married."

Xie Li wanted to say something to comfort her, but as soon as he opened his mouth, Tang Wanwan immediately turned around and rubbed his head with ashes on his palm: "Don't comfort me, I'm so happy."

Xie Li always felt that there was something unclear hidden under her smile, but she couldn't bear to explore it.

He didn't sit for too long, Tang Wanwan was too busy directing the workers to move, so he didn't have time to talk to him

Xie Li stood up and said goodbye, Tang Wanwan called him again: "Xiao Li."

She dismissed the workers and walked up to Xie Li: "I heard that you have submitted an article, congratulations."

Xie Li scratched his head: "I don't know the result yet."

Tang Wanwan was quite determined: "Don't be modest, can you still not count the things you make? The teacher wants you to go abroad, do you have any plans?"

Xie Li sighed, shook his head, and didn't want to answer this question.

Tang Wanwan saw his hesitation, told him to wait, turned and went into the bedroom, and came out after a while, holding a colorful stone in his hand.

"This is when the foundation stone of Suiye Station was laid, and we picked up a stone by ourselves. Do you see a big red spot here, does it look like the eye of the storm on Jupiter?" Tang Wanwan put the stone into Xie Li's hand, "Xiao Li, I have always felt that you were born to look up at the starry sky. Maybe one day, all of us will see more wonderful things through your eyes. You must go towards the things you love, and don't worry about anything. Things shake."

Tang Wanwan pointed to himself: "I am a lesson learned from the past. I wavered and compromised. I thought I could endure it, but in fact I couldn't. People are the same, understand? Your boyfriend is good, but you are better .”

She took Xie Li's hand: "You should go out, so that one day in the future, you won't regret it yourself, and you won't blame him."

When Xie Li came out of Tang Wanwan's house, the stone was already warmed by his body temperature.

He stood on the side of the road in a daze for a while, and finally turned around and went back to school.

Shen Zhichuan was surprised to see Xie Li at the door of the classroom before get out of class ended.

He was being surrounded by several students asking some stupid questions that he had emphasized several times in class, and he became more and more impatient, so he simply waved his hand to signal Xie Li to come in.

"Come over here and tell them a few about this Debye shield."

The end of the term was coming soon, Shen Zhichuan was notorious for not giving sample questions or demarcating the scope, so the students had no choice but to grab him and ask questions.

Xie Li had no choice but to come in, and under the eager eyes of several undergraduates, he took the exercises in the opponent's hands, glanced at them, and immediately pointed out the problem: "Non-neutral plasmas also have Debye shielding effects. It was wrong from the start.”

He went on to look at the next question, but only glanced at it, and it took less than two seconds: "The spatial scale smaller than the Debye length, and the time scale of the response time, is to apply an instantaneous strong electric field instead of a local strong electric field. "

Shen Zhichuan leaned halfway on the podium, watching his proud disciple sweep the weaklings, he felt completely refreshed, and finally clapped his hands: "My doctoral students will do the questions in their freshman year, and you will use them to ask others when you graduate soon, Is this level going to apply for a school district room in the school?"

Several undergraduates were disgraced and fled with tears in their eyes.

After venting the grievances he had accumulated throughout the semester, Shen Zhichuan felt relieved, and turned his head to Xie Li with a loving smile: "What's the matter with you?"

Xie Li pulled the strap of his schoolbag and leaned over: "Teacher, I want to ask, if I want to go abroad, how much money do I need to prepare?"

Shen Zhichuan was even more surprised.He raised his eyebrows and looked Xie Li up and down, wondering if there was some trap behind Xie Li's question for not going abroad.

"See how you got out. Anyway, there is always a way to get you out." Shen Zhichuan didn't give him an accurate answer, "Why? Figured it out?"

Xie Li nodded: "I want to understand first."

The author has something to say:--

Tan Ke: What should my child bring with him when he wants to go abroad?

Assistant Xiao: Money.
