"Breakfast is prepared for you on the table. Eat it while it's hot. It will cool down after a while.

I heard from your dad that you stayed up until past two o'clock last night?

I’ve told you, don’t always stay up late taking advantage of your youth, it’s not good for your health…”

After Zhao Xiancai finished washing, his mother Wang Qiuyue said to him and began to chatter.

It seems that no matter how successful her children are, a mother can always find something to talk about.

"I was too involved last night. I originally wanted to watch it for a while and then go to bed. I will try not to stay up late in the future."

Zhao Xiancai defended himself.

After saying that, Zhao Xiancai sat at the dining table and started eating breakfast while scrolling through his mobile phone.

It was only then that Zhao Xiancai saw the news reports and related comments on the Internet about his winning of the Crafford Award.

"I just received a call from the Royal Swedish Academy of Sciences last night. I didn't expect that this matter would become known to everyone so quickly."

Zhao Xiancai thought this when he saw that the news that he won the Craford Mathematics Prize was still on the hot search.

Just when Zhao Xiancai was scrolling through his phone and almost finished breakfast, he received a message.

"Are you on vacation now? Have you returned to China?"

"I'm on vacation, and now I'm lying at home every day."

Zhao Xiancai replied.

"Then are you planning to go back to Beijing University to visit before you go back this time?"

The person who sent the message to Zhao Xiancai was none other than Ding Daoliang, one of Zhao Xiancai’s roommates at Beijing University.

"Originally I didn't plan to go back, but I just received a call from Professor Yang. He said he was going back to Beijing University in a few days."

Zhao Xiancai replied.

"Really? When are you coming to Beijing University? I want to treat you to a meal and discuss something with you."

Ding Daoliang replied that he did not ask Professor Yang why he called Zhao Xiancai or what Zhao Xiancai was doing when he returned to Peking University.

"Isn't the school already on winter vacation? You haven't gone back yet?"

"No, I applied to stay in school during the winter vacation this year."

…

Although Ding Daoliang did not tell Zhao Xiancai his purpose clearly this time, Zhao Xiancai had already guessed Ding Daoliang's purpose when he saw the first message Ding Daoliang sent him.

Because Ding Daoliang had contacted him before and told him about this matter.

When Zhao Xiancai was leaving Peking University and going to Princeton, someone in their dormitory jokingly said that if they went to graduate school in the future, they might ask Zhao Xiancai to be their mentor.

However, at that time, they said that no one really thought that Zhao Xian could lead graduate students when they were in graduate school.

After all, when Zhao Xiancai graduated from Peking University and went to Princeton University for graduate school, it was only two years ago in 2016, not even two years ago.

From undergraduate graduation to graduate school and becoming a teacher with postgraduate guidance qualifications, two years is not enough.

Even for a math genius like Zhao Xiancai, it took him two years to complete his undergraduate studies. Naturally, his roommates would not have thought that it would only take two years for Zhao Xiancai to be able to lead a graduate student from the beginning.

However, Zhao Xiancai's promotion speed later exceeded their expectations.

After Zhao Xiancai was hired as a professor of mathematics at Princeton University with an annual salary of one million US dollars, many people at Peking University began to think about going to Princeton University and choosing Zhao Xiancai as their tutor.

The Department of Mathematics at Princeton University did receive a lot more applications from Peking University students last year than in previous years, and the tutors they applied for were all Zhao Xiancai. However, in the end, Yang Biwen was the only Peking University student who passed the examination and became Zhao Xiancai's graduate student.

Among the Peking University students who want to go to Princeton University and choose Zhao Xiancai as their graduate tutor, there are Zhao Xiancai’s former roommates at Peking University.

But even students from Peking University can’t just go to Princeton University if they want to. There are only a few people in China who can go to Princeton University to study for graduate studies in mathematics every year, and even fewer people from the School of Mathematics at Peking University can go to Princeton University every year.

.

Among Zhao Xiancai's roommates, Cui Pingge entered Peking University with the third highest score in the Jiangsu Province College Entrance Examination, but he had no extraordinary talent in mathematics, and later fell in love with a semester student.

, naturally I didn’t think about applying to Princeton University.

Although Zhang Qiuyu has participated in mathematics competitions, not to mention Zhao Xiancai, even compared to Ding Daoliang, Zhang Qiuyu is not very good at mathematics. After all, when he first joined the training team, his grades were at the bottom.

Ding Daoliang was considered to be the person with the highest mathematical talent besides Zhao Xiancai in Zhao Xiancai's dormitory. Not only did he get full marks when he entered the training team, but his performance in the training team was also very good.

Coupled with the fact that Ding Daoliang studied hard after going to college, Zhao Xiancai and the other three in his dormitory have the best chance of going to Princeton University for further studies.

And Ding Daoliang did have this idea.

This time Ding Daoliang said that he applied to stay in school during the winter vacation. Needless to say, Zhao Xiancai knew that his purpose was to stay in school and study hard so that he could pass his own assessment later.

The purpose of his contact with Zhao Xiancai this time was also to talk to Zhao Xiancai about this matter.

After breakfast, Zhao Xiancai returned to his room and continued to do what he had not finished last night.

It wasn't until his mother called for dinner at noon that Zhao Xian came out of the room.

When Zhao Xiancai finished lunch and returned to his room to continue reading the information about complex climate systems that he had just finished reading, a message box popped up in the lower right corner of his computer.

"Huh? So fast?"

The message prompt was an email. When Zhao Xiancai clicked on it and read the contents of the email, he was a little surprised.

The email Zhao Xiancai received was sent by Zhou Xianming.

As for the content of the email, it was naturally about the paper titled "Accelerating the Aging of All-Inorganic, Interface-Stable Perovskite Solar Cells."

According to Zhou Xianming, this paper has not only been reviewed, but can also be seen in the latest issue of "Science" on the official website of "Science". In the email he sent to Zhao Xiancai, at the end was attached

Got the link.

However, Zhao Xiancai did not click on the link attached at the end of Zhou Xianming's email. Instead, he continued to read information about complex climate systems after closing the email page.

Through in-depth research on mathematical modeling and a gradual in-depth understanding of complex systems during this period, Zhao Xiancai also gained a deeper understanding of the establishment of mathematical models.

But just when Zhao Xiancai was immersed in the world of knowledge, the outside world once again exploded because of him.
