Chapter 893: Please read the blog

Shuwulou, the latest chapter of the black technology system of Xueba will be updated as soon as possible!
Although when Lu Zhou was in Princeton before, he did occasionally communicate with some scholars studying economics, but he was not so familiar with anyone.
I can't talk to him anymore, he must remember his name, right?
Besides, Princeton is so big, he only stayed for so many years, and he may not have seen this man.
After carefully searching the names in his memory, Lu Zhou didn't find anyone who could match his name. It wasn't until he logged into the academic inquiry website and entered the name that he found out who this man is.
The results are not searched, I do n’t know, and the search is not small.
Krugman!
Winner of the 2008 Nobel Prize in Economics!
Expert in international trade, exchange rates and macroeconomics!
The most brilliant piece of his academic resume was the successful prediction of the Asian financial crisis in 1997 in 1994. This prediction made his position in economics as high as ever after the outbreak of the Asian financial crisis. Nobel Prize in 2008.
But what surprised Lu Zhou was why he contacted him.
The main idea of ​​the email is to ask him when he has time and want to talk to him about academic issues in person.
Although not very interested in economics, Lu Zhou edited a reply and sent it after thinking about it for a moment.
[Tonight at 8pm Beijing time, if you are free, we can talk. 】
After all, scholars who have won the Nobel Prize still have to give a little face.
Anyway, he's on vacation, and he's idle ...
...
eight pm.
At the appointed time, Krugman appeared in the video call.
The professor who met for the first time even omitted the self-introduction, and almost just connected the video call and said in an impatient tone.
"You don't know how important your research is!"
Being suddenly confused by this sudden speech, Lu Zhou hesitated slightly: "... I really don't know very well, not even what research results you are referring to ... can you tell me?"
Taking a deep breath, Krugman explained.
"The Bewley model has always been the forefront of macroeconomics. Your improved model ... I will call it the Lu-Bewley model for the time being. It not only solves the problem of the huge calculation and complicated steps of the Bewley model, the most important thing is to reduce Random errors of the model! "
Bewley model?
It turned out that Xiao Tong's paper ...
After listening to Professor Krugman's description, a faint expression finally appeared on Lu Zhou's face.
However, it was only a stun, and there was no expression of interest that Professor Krugman was expecting.
Seeing Lu Zhou not talking, Professor Krugman thought he didn't understand what he meant, so he cleared his throat and continued.
"Let's put it this way, taking all the complicated research away from it, the ultimate goal of economics is only two, one is to optimize the efficiency of resource allocation, and the other is to coordinate the interests of society! If we can obtain an accurate model, even as much as possible Accurate models. From the height of civilization, we can optimize the allocation of resources to the maximum! From a personal perspective, we can even predict the future through economic activities! "
Finally reacted to the word predicting the future, Lu Zhou leaned back in his chair.
"It sounds incredible."
With a smile, Professor Krugman watching the video call, Lu Zhou continued, "I don't understand the principles of economics, but for chaotic systems ... it seems that no mathematical model can ever achieve 100% Prediction. Even if I just give an example, how do you predict the birth of controlled fusion technology? And how do you predict its impact on the global economy before it is born? "
"I can't answer this question, but this is not the point you are talking about," Krugman shook his head and continued. "I can tell you that technological progress can theoretically use R & D investment, GDP ratio, etc. The parameters are summarized in the model, even if you cannot understand, I can tell you clearly that this is a Nobel Prize-level discovery! As long as you continue to study the mathematical improvement of the Bewley model, I am sure of Nobel Economics The prize must belong to you! "
"But ... I have already won the Fields Prize," Lu Zhou shrugged, and continued, "I have also won one of the Nobel Prizes."
The atmosphere in the video was awkward for a while.
Professor Krugman gave a cough and persuaded.
"Don't you want to take another one? This is the Nobel Prize ..."
"For me, the appeal of the Nobel Prize is not as great as it used to be," Lu Zhou sighed. "Do you know? Compared to what kind of honor I can get, I am still fascinating enough. Interested in a difficult problem, can you understand this feeling? Dear Professor Krugman. "
"..."
Krugman didn't want to answer.
He even wanted to throw the pen at hand on the screen.
A young man in his twenties told him that he had no pursuit of honor.
Well, even if this guy does have the qualifications to say that, it's too irritating!
Taking a deep breath, he tried to persuade.
"Isn't the Bewley model enough to arouse your interest? This is also a sufficiently important problem! And it's difficult enough! I can tell you in a responsible way that he can change the world directly than any purely mathematical study — — "
"That's not necessary," interrupted Professor Krugman's words, Lu Zhou smiled and continued, "And, improving the Bewley model ... or the Lu-Bewley model as you said, it only cost me a total It's only an hour, and no matter how you look at it, it doesn't look difficult. "
One hour……
Krugman was there.
Instinct told him it was absolutely impossible, but the person watching the video didn't seem to be joking or lying.
To put it plainly, what good is it to lie to him?
However, in an hour, the Bewley model was improved to such an excellent level ...
This is really terrifying!
"That's all for now," said Professor Krugman, who couldn't say a word. Lu Zhou looked at his watch and yawned. "I'm sorry, but I can't help you too much. Princeton has Many good math professors, maybe you can take my model and ask them for help. "
"So, goodbye."
The video call is over.
Looking at the black screen, Krugman remained silent for a long time, stretched out a slightly trembling finger, and took off the glasses on the bridge of his nose.
He has been watching the conversation between the old man and Professor Lu. His student Weisser swallowed and said.
"professor?"
Krugman sighed and shook his head.
"I can only think of another way."
Princeton does have a lot of excellent mathematics professors, but not many professors interested in economics, especially those who are engaged in theoretical research. Many people have a lot of prejudice against applied disciplines, and think that they study these Is a waste of time.
After all, a big man in the mathematical world entered this field and made a little bit of results. Where would he easily let go.
Like a giant panda slipping into the zoo, can he let you go?
Krugman was lost in thought, and at this moment, he suddenly moved.
At this time he suddenly remembered that there seemed to be another author in the paper.
It's not a foster.
He has never heard of this name, and it is probably a lucky guy.
But the name of the second work ...
Eyes gradually brightened, and Krugman looked at his students and said immediately.
"Weissl!"
Suddenly called by name, Wiesel responded immediately.
"I'm ... what do you want?"
"Help me write an e-mail, and I will give you my e-mail address in a while, then fill in Lu · xiaotong with my name and the recipient's name ..." After a pause, Krugman muttered to himself. "If things go well, you should be able to catch up."
Although the voice of this sentence was not loud, it happened to be heard by Wiesel who was busy editing the mail.
When he saw it for a moment ~ EbookFREE.me ~ he asked subconsciously.
"What can you catch up with?"
"Filling volunteers, or choosing a mentor or something," paused, Krugman continued, "remember the paper I let you see? Although that paper was only part of the mathematical model , But being able to sort out the theoretical part completely, and letting a mathematician who has no knowledge of economics to make such an important study is also a rare quality in itself ... if I guessed right, she should not have been Decide where to go for a PhD! "
Wesley hesitated, and put forward a hypothesis.
"But in case she doesn't plan to continue on the academic path?"
Krugman flatly denied.
"impossible!"
"To be able to write such an excellent dissertation, it is absolutely impossible if she does not intend to go down the academic road! It is simply not necessary to achieve this level just for graduation!"
"Just send the emails as I requested."
"Yes ..." With a serious look at the boss, Weisser nodded his head and turned on the computer to start editing the mail.
Buried in editing the mail, the doctor in his thirties was also impressed.
Every time in the graduation season, others are all kinds of magnetic recommendation letters, reducing their heads in order to get Daniel recommendation. However, this lucky guy is better. Don't say any recommendation letter. The Nobel Prize Winner personally sent an email to invite her to read the blog ...
This treatment is no one.
He even heard for the first time that such a good thing happened.
Thinking about it, thinking of the experience of studying in the beginning, Weisser's mind was just like lemon, and the overflowing sour taste was soaked in the email ...
Fack!
What a special envy!
