As the days go by, "Chunhua" is about to turn into "Autumn Fruit", the new school year is approaching, and all over the country, college freshmen are preparing for the start of school and looking forward to a better life in the university.

In the orientation group, the seniors and seniors also used their own "eighteen martial arts", pretending to be * in the orientation group, attracting the attention of rookies, eager to get a primary school girl or a primary school brother.

And this summer is only the cool air conditioning in the office and Qin Jing's excellent cooking skills for Han Sen.

Of course, a summer has passed, and now it is also the harvest season for Han Sen.

Under the cool air conditioning in the office, Han Sen finally sorted out the two thick papers:

A mathematical paper: "A Brief Analysis of Fermat's Great Theorem - Encryption of Prime Factors in Large Integers"

An economics paper: "The Impact of Cross-regional Internet Clearing and Payment on the World Economy".

The focus of these two papers is the mathematical paper "Analysis of Fermat's Great Theorem - Large Integer Prime Factor Encryption".

Han Sen did not directly throw out the proof of Fermat's theorem, but stripped off a part of it, and using Fermat's theorem as a tool, Han Sen proposed an encryption algorithm, which will have an extremely important impact on Internet information security.

With the support of encryption for information transmission, Han Sen's second paper on cross-regional financial clearing and payment has practical support, which will have a crucial impact on the global financial system.

As long as the results of these two papers can be accepted by the world, then after Han Sen throws out the "nuclear bomb" of "Proof of Fermat's Great Theorem", Han Sen will encounter a lot less suspicion and resistance.

......

The mathematical papers were sent directly to his supervisor at Princeton University, Professor Lambert, a member of the Sam's National Academy of Sciences and a Fields Medal winner, and one of the professional editors of the Annals of Mathematics.

The economics paper Han Sen sent directly to Berkman the editor-in-chief of the American Economic Review.

The American Economic Review is one of the most prestigious academic journals in the field of economics in the world, founded by the American Economic Association (AEA) in 1911.

The American Economic Review was founded to enable readers to understand and grasp the development process of economic ideas and major economic events; His research covers various fields of economic theory, applied economics and economic policy. The focus of the topic changes according to the concerns of the economics community. The papers published in the American Economic Review have a great "weather vane" significance, and basically lead the research topics of great significance to the economic community at present and in the next few years. Over the years, almost all of the Nobel laureates in economics and the world's most prominent economists have published important academic papers in the American Economic Review.

Of course, in addition to the top economics journals of the American Economic Review, there are other journals such as The Economist, but Hansen worked with Berkeman, the editor-in-chief of the American Economic Review, when he was working at the Federal Reserve, so Hansen sent his paper directly to Berkeman's personal mailbox.

......

Princeton University, Han Sen has been away from here for more than half a year, as Han Sen's graduate student and doctoral mentor, Lambert now regrets letting go of the "Oriental Kid" so early, because after Han Sen left, Lambert did not find a student who could be used as easily as Han Sen.

In Lambert's office, the assistant prepared a cup of coffee, Lambert opened the mailbox, and directly opened his student's email, a few MB of PDF files, Lambert looked at the topic, and immediately became interested: "Analysis of Fermat's Great Theorem - Encryption of Prime Factors of Large Integers"

"This kid has challenged Fermat's theorem, let me see how you've been doing!"

Han Sen's paper directly crossed the review editor and entered the field of vision of professional editors.

......

At Yale University, Berkman opened his mailbox after returning from a meeting at the Federal Reserve, and countless emails poured in to him in an instant, and after a brief browsing, Berkman found a familiar name "Sen Han".

Parkman still feels very sorry for Han Sen, during his work at the Federal Reserve, Han Sen showed a strong mathematical talent and a solid mathematical foundation, and as a Chinese, he has a very comfortable etiquette, in the Federal Reserve, many people like him very much.

Hansen is responsible for the mathematical model of many of the Fed's policy analysis reports, and Hansen is also involved in the "Bitcoin" plan as a mathematical consultant, and if Hansen is a white man, Parkman feels that Hansen is likely to impact the future Fed chairman.

But unfortunately, due to geopolitical reasons, it is impossible for a Chinese person to rise in the Fed.

Seeing Han Sen's paper, Parkman was quite happy: "Sen Han? That Oriental Kid! Let me see what he sent me. ”

......

Han Sen's two papers came into the editor's field of vision, and as for whether the papers could be published, Han Sen never worried.

After sending out two papers, under the air conditioning in the office, Han Sen sorted out piles of documents one after another.

......

At the same time, the dean's office of PBC, Dean Wu Ling carefully reviewed the expenses of the college in the last academic year, as the dean of PBC College of Tsinghua University, Wu Ling has a natural sensitivity to numbers, and there is no need to find historical data for comparison.

Wu Lingzou frowned, and asked Li Wenyao, the director of the logistics department who was sitting in front of him: "Director Li, why did there be so many more consumables in the office last school year than in previous years!" ”

At this question, Li Wenyao immediately began to complain: "Oh, Dean Wu! If you don't look at it, just the A4 paper, Professor Han has used a whole car in more than three months! The staff of our logistics department all carry paper for Professor Han, you must know that most of our logistics department are little girls! I've received a lot of complaints! ”

Li Wenyao proposed a "Professor Han", and Wu Ling was still thinking in her brain, which Professor Han? Is there a professor surnamed Han in the academy?

Huh, Professor Hansen? What does he look like? Isn't it quite young? What is he doing?

After thinking about it carefully, Wu Ling found that she hadn't seen Han Sen for a few months, and she had forgotten what he looked like, and asked, "What is he doing with so much A4 paper!" ”

"How dare I ask!" In Wudaokou, the status of a scholar is above all else, how can Li Wenyao, as a logistician, dare to ask about a professor's affairs.

Wu Ling thought for a while and said, "You go to the teaching and research department to help me call my doctor named Zhang Bin, let's go to Professor Han to have a look!" ”

......

For more than three months, Han Sen got up at half past five every morning, and when many people were still enjoying the comfort of the bed, Han Sen ran from home to school on time, and started the day's work after changing clothes in the office.

Then until 10 o'clock in the evening, I changed into sportswear and ran home.

As for the beautiful Lexus, Han Sen had already said goodbye to it after driving it a few times, and now this car is basically driven by Qin Jing, there is no way, you have to pay for eating other people's food all day long, and if you can't dedicate yourself, you can only sacrifice the car.

The result of several months of early entry and late exit was that everyone in the academy, from teachers to students, had not seen Han Sen for a long time.

Of course, Han Sen, who had no teaching tasks and no administrative status, no one cared about him, after all, no one had an interest in him.

But if Han Sen added the title of "Director of the Infrastructure Division" to his head, even if Han Sen ran to the ends of the earth, someone would be able to find him.
