He shook his head and left Qingcheng No. 1 Middle School.

This time I came to Qingcheng No. 1 Middle School at the invitation of the principal. Unexpectedly, there was also a county leader. Then this county leader was testing whether there was any way to invest in Qingcheng in the Kowloon era.

Naturally, Liu Yichen declined politely.

It's not because I don't want to repay my hometown, but Qingcheng doesn't have the conditions. Firstly, transportation is inconvenient. Although there are county roads and provincial roads, there are no expressways and train stations. Although there is a train station, the speed is too slow. Secondly,

There is no factory in Qingcheng. Even a small lithium-sulfur battery factory would require 500 acres of land. Where did Qingcheng get 500 acres of land?

At present, Jiulong Times has formed a preliminary strategy, which is to set up a production base in Jiangcheng and Chang'an. The three places basically form a line and form a national strategic fulcrum. Setting up a production base in Jiangcheng can radiate to the entire central and western regions

At the same time, it can also be transported to various places through deployment, railways and water transportation. The production base is set up in Chang'an because there are many military industrial enterprises here, which will facilitate the future production of lithium-sulfur batteries for military industry.

Once the three production bases are completed, coupled with BYD's OEM production, they will not only be able to meet China's demand for lithium-sulfur batteries, but also the world's needs. There is no need to set up other production bases.

After all, at that point, the production base alone had 180,000 employees, and the explosion of productivity was already extremely terrifying.

Liu Yichen also had to think about a question, that is, where is the road for Qingcheng? Although the Kowloon era purchased tens of millions of yuan of tea in Qingcheng every year, there is no doubt that it is only a drop in the bucket for the development of Qingcheng. It is just left to its own devices.

He couldn't think of any industry that could be developed in this place.

If you want to get rich, build roads first!

This principle really makes sense.

Transportation is inconvenient and development is difficult.

The seven-day Spring Festival holiday, spent visiting relatives and friends, passed quickly, and Liu Yichen and Feng Lin had to embark on a trip back to Princeton University.

...

Institute for Advanced Study in Princeton

This research institution is nominally independent of Princeton University, but in fact it is closely connected to Princeton University.

For example, he is a professor at the Institute of Mathematics at the Institute for Advanced Study and a professor at Princeton University.

In just one Institute of Mathematics, there are more than 10 Fields Medal winners, which is enough to reflect the strength of Princeton Institute for Advanced Study in mathematics. Its reputation as a world mathematics center is not in vain.

Liu Yichen ran a programmed program on his computer, looked at the progress bar above, with a faint smile on his face - the plan of 'Deep Chen Cang' was officially launched.

The Internet is like capillaries throughout a person's body, and through the Internet, one can collect and obtain what he needs.

"Liu, how are you? Which category of mathematics report do you plan to give at this academic conference?" Philip Griffith asked with a smile: "We are doing statistics now. Tell me and I will help you register. I suggest you best

The good thing is Goldbach's conjecture, I think it will definitely be very popular."

"Griffith, forget it, I will not attend the academic conference this time." Liu Yichen shook his head and said.

"Why? You know, you are the most popular person now! Everyone is studying your group construction method!" Griffith said in confusion.

If anyone is the most popular in the mathematics community right now, it is Liu Yichen.

Throughout last year, we have successively proved the weak Goldbach conjecture, the twin prime conjecture, the Polynian conjecture and the Goldbach conjecture, which can be said to have caused a sensation in the entire mathematical community, especially the proof of Goldbach's conjecture, which became Perel's

It is the most important achievement in mathematics since Mann proved Poincaré's conjecture. In the field of number theory, it is the most important achievement after Wiles proved Fermat's last theorem in 1994. It cannot be overestimated.

Everyone knows that for the 2014 Fields Medal, one of the four places has been locked up. No matter how outrageous the jury is, it is impossible not to award the Fields Medal to Liu Yichen.

"Griffith, I won the first prize in natural science in our country. I have to attend the award ceremony!" Liu Yichen said with a faint smile.

Yes, the 2011 National Science and Technology Awards Conference is about to be held, and Liu Yichen has received the invitation. His research results on Goldbach’s conjecture won the first prize of the National Natural Science Award. This will also be the second time he has won the award.

It is also the first time in the Chinese scientific community that someone has achieved great success for consecutive years.

In Liu Yichen's mind, the National Science and Technology Awards Conference is much more important than the Princeton Academic Conference.

"Well, I think this is the biggest regret for scholars who come to Princeton." Griffith said regretfully.

The environment at the Institute for Advanced Study in Princeton is quite relaxed and free. Liu Yichen likes this environment very much. Instead of studying other things, he studies modern algebraic geometry. The books he borrowed from Professor Deligne are quite precious.

Because one of them is the original manuscript of the "Pope of Mathematics" Grothendieck, which is undoubtedly the most precious and priceless to mathematicians.

By looking directly at the original manuscript, you can experience the original author's thoughts and ideas, and then draw wisdom from them. This is different from articles. The published articles have been compiled and improved, and the original author's thoughts and ideas can no longer be seen.

Got an idea.

"His Majesty Grothendieck's wisdom is really amazing. If he had not been in war when he was young, he would have achieved even more brilliant achievements." Liu Yichen said with admiration.

He could not imagine that Grothendieck's wisdom had reached this level half a century ago, and some of his thoughts were truly unimaginable and unimaginable.

Perhaps it was such a super genius who was able to single-handedly create the modern algebraic geometry empire. Even after 40 years away from the mathematical world, his legend is still circulating in the mathematical world.

Witnessing with his own eyes and experiencing the horror of war made Grothendieck an extreme pacifist. At that time, Grothendieck, who believed that he had dedicated all his wisdom to mathematics, waved his hand to the mathematical community,

Regardless of the mathematics community's attempts to retain him as the 'Pope of Mathematics', he resolutely devoted himself to the peace movement and ecological protection movement. The Fields Medal was awarded to him, but he didn't even bother to receive it. The Crawford Medal was awarded to him, and he also

He refused, and his reason was that his professor's salary and pension were sufficient for his needs, and the award gave the researcher an excessive social status and reputation. He stayed away from the scientific community in 1970. He was a pacifist!

It can be said that Grothendieck was a quite pure mathematician, and scholars like him are not uncommon in the mathematics world, such as Perelman!

Liu Yichen sometimes had to lament the purity of these people and their most sincere love for mathematics, something he thought he could not do himself.

He even felt that without the system, he would be just an ordinary person, a scumbag in the eyes of top academics.

"What good thing happened to make you so happy?" When he returned to the dormitory, he saw Feng Lin smiling and looking very happy.

"My royalties last month were this amount!" Feng Lin extended a slap in the face, pleased with herself.

"Five thousand dollars?" Liu Yichen was quite surprised: "That's right, the increase is good, maybe you will be the next best-seller!"

"No, no, no, it's fifty thousand dollars!" Feng Lin said proudly.

Liu Yichen was astonished. This meant that in January, Feng Lin's book sales exceeded 33,000. This sales volume was already a miracle for an unknown scholar and a very unpopular introduction to Eastern Europe.

"You can do it, it will become a bestseller!" Liu Yichen couldn't help but praise: "If I published a book in the United States, I might not be able to sell 10,000 books a year!"

"Look at Twitter and Facebook. They all praise me for my good writing and giving them new perspectives and ideas!" Feng Lin opened Twitter and Facebook and said proudly.

Obviously, the surge in book sales in January gave Feng Lin a great sense of accomplishment.

Liu Yichen naturally praised him very much.

Following this trend, Feng Lin's second book will be published in a few months. I think with the foundation of the first book, the sales of the second book will not be too bad.

In fact, in Liu Yichen's view, Eastern Europe is worthy of analysis. Firstly, it has been ignored by the academic community intentionally or unintentionally and is not a hot area for research. Secondly, the geopolitics here are very complicated, involving the world's major forces, and are intricate. In fact, it is a huge

of hot spots.

Of course, there is also the world's most prodigal son here, which is also an extremely legendary story and deserves to be written down.

This is why he initially guided Feng Lin to study this area, and as the research deepened, Feng Lin really researched something. This can be seen from the improvement in the depth and breadth of the articles written by Feng Lin.

In Liu Yichen's view, Feng Lin's progress has been very significant after almost four years since high school. Her academic level is actually enough to obtain a doctorate from Princeton University.

Feng Lin's doctoral topic is not the Eastern European Plain, but Southeast Asia. The economic growth in Southeast Asia is very fast, which is particularly eye-catching. However, Feng Lin's current experience is more in the Eastern European Plain, in Southeast Asia.

Academic research has not yet begun.

Liu Yichen is not worried that Feng Lin will not be able to obtain a doctorate, because Feng Lin's academic research in the Eastern European plains is actually enough to obtain a doctorate from Princeton University. The tutor's project belongs to the tutor, and it is normal not to complete it. The focus is still on academic attainments.

.

The happy Feng Lin is always very relaxed, allowing Liu Yichen to enjoy the rare enjoyment, and this time is no exception...

It was just the Tomb of the Heroes of Wenwen Township. A few days later, Liu Yichen had to leave Wenwen Township and embark on a journey back to China because the National Science and Technology Awards Conference was about to begin.

Liu Yichen always stands firm enough in the face of major issues of right and wrong.
