Chapter 1315: Affects more than physics

There is a weird pair in Princeton.
That was Paul Krugman and Professor Albert Laslobara Brazil.
The reason why the pair is strange is not because of what happened between the two people, but because the subject they are studying is hard for the average person to understand. Even after listening to the avant-garde principal, Isgrub, he only gave an inexplicable look and did not make any evaluation.
Speaking of the two people's acquaintance, it is also full of many surprises.
At first it was because the business cards were exchanged at the dinner after an academic conference. Later, they agreed unexpectedly on the grand proposition that explores where humans will go in the future. This led to the "quantitative analysis of this through mathematical models." Evolutionary process ".
It happens that one of them is an economist who is passionate about natural sciences, and the other is a physicist who is passionate about sociology. They can complement each other in their respective professional fields.
Although unfortunately when they were in St. Petersburg, they failed to pull Lu Zhou together to study the mathematical model for predicting the future, but even without the help of the world's best mathematician, the two did not give up on this. Continue to work hard in the direction.
Although there is no obvious progress in related research so far ...
In the cafe near the school building.
As usual, the two were sitting opposite each other, enjoying some afternoon tea, and talking about some inexplicable topics while enjoying their afternoon tea.
"... For interstellar high-speed travel, the theory of relativity determines the existence of time expansion in different coordinate systems. If there are a pair of twin brothers, one day my brother will board a spaceship and go to civilization A for a long-distance space trip, while my younger brother will He stayed on the earth. When my brother returns to the earth, we will find that he is younger than his younger brother who stays on the earth ... I have no problem reading this. "
Listening to Professor Krugman's speech, Albert nodded with interest and said, "No problem ... but what does this mean in economics?"
"It just doesn't mean anything like this, but if we replace the twin brothers with two speculative businessmen, the results will be very different. You know, time is a very important cost in business. If the profit of a trade route is not as good as the regular interest of the parent bank, then this flight will not be profitable. "
"There is a formula involved," scribbled a line of formula on the note paper, and Krugman pushed it to Professor Albert with his index finger. "It is the starting point of everything."
[Pe qepa / pa ≥ (c + peqe) (1 + r) 2n. 】
Taking a closer look at the formula on the note paper, Albert raised his eyebrows involuntarily.
"... a strange formula."
"It's weird, but it contains a very important theory that is my first theorem of interstellar trade," Krugman smiled proudly and continued, "between the planets of the same inertial coordinate system When trading, the interest calculation should use the clock of the planetary inertial system, not the clock of the spaceship system. At the same time, let the interest rate of the Earth Bank be r. . "
Albert: "Interesting point ... Speaking of which, if there is a first theorem, is there a second theorem?"
"Of course, due to the existence of trade competition, the planets of the same inertial coordinate system will gradually approach the same interest rate. This is the second theorem ... However, they are now void, probably," the old man giggled, although he said The results are full of regrets, but his voice sounds quite pleasant. "All these theories are based on the absolute correctness of relativity, that is, we have not found a standard beyond the speed of light."
"Although the theory of relativity is still correct, we have found a shortcut to an alien planet ... at least in theory. When time does not swell and flight time is shortened, we don't have to think about the long The journey may wipe out simple arbitrage. "
"In fact, what I really want to say is ... didn't you notice? That hyperspace theory affects not only physics, but also economics."
Hearing this sentence, Professor Albert was lost in thought.
After a long time, he sighed softly.
"You are right, scientific progress has brought great uncertainty to mathematical models. Even with perfect and rigorous calculations, it is difficult to predict such a non-linear leap forward. Even our mathematics The model successfully predicted what might happen in the next 100 years, but as long as there is a 'Professor Lu' in this 100 years, we can reverse all our predictions. "
Krugman nodded slightly.
"What I am worried about is that studying the overall changes of civilization must weaken the role played by the individual in the process of civilization, but when the role of the individual cannot be ignored, the process will no longer conform to objective laws."
Just then, a young man walked quickly outside the cafe.
He was wearing a gray suit and looked a little unusual, as if he had just seen or heard something incredible. I saw the man walked straight to the two professors and said in a tone like dreaming.
"professor……"
"Good afternoon, Dr. Milson," looking up at his assistant, Professor Krugman smiled kindly, "What makes you look so surprised."
"You asked me to gather information about the Tiancang Five Alien Colony Fund ..."
"Is there any news?"
"Yes," Mumu nodded, and the assistant hesitated for a while before he said in a difficult tone, "that fund ... seems to be Xiaotong in charge of management."
"... Xiaotong?"
Krugman froze.
After a while, he returned to God. He sat upright from the chair, looked at his assistant with disbelief, and asked, "Wait, what do you mean ... your sister? That little Tong ? "
The assistant said with a grin.
"Yeah ... this is already a public matter."
He opened his mouth indifferently, and after a long silence, Krugman said.
"I see ... let's do it for the time being."
The assistant nodded and turned away.
Leaning back on the chair, Krugman frowned slightly.
Originally in his plan, he also planned to find a way to contact the manager of the fund that has recently gained a lot of attention in the economics circle, have a cup of afternoon tea or something, exchange academic questions, and complete the idea he is conceiving. That subject.
But now ...
He really did not expect that this person would be his own student.
"Can't believe it ..." Albert, who was sitting opposite, opened his mouth and looked at Professor Krugman with a grimace. "It's ... your student is taking care of this fund."
That's 10 billion!
And not just a casual thing like a graduation thesis!
It's not that he doubts Xiaotong's ability, but does a normal person give so much money to a doctoral student who hasn't graduated yet to manage it?
"It does sound strange ..." Putting down the index finger and thumb pressed on the eyebrow, Professor Krugman's face showed a complex expression, "... but it really seemed like something he could do. "
In fact, Xiao Tong's ability is good, and he is usually very hard.
The only thing missing is probably practical experience.
In fact, according to his mentor's point of view, it may be better for her to start with a small assistant. It is too risky to start such a difficult job directly ...
But how do you say that?
If you don't care about hundreds of millions of gains and losses, you can ignore these problems.
It's one of her advantages to have such a brother who is not bad at money ...
"... Unlike other students I have taught, she is one of the few who can achieve a balanced development between theoretical and applied economics, especially in a place like Princeton, who wants to do both and do it all It's not easy to get to the point. "
Albert asked with a sip of coffee, curious.
"Is she talented?"
"Not the most gifted," Krugman shook his head. "But she's probably the hardest."
And the starting point is much higher than the average person.
Facing the aura of the Nobel Prize winner's sister, even Lu Zhou did nothing, relying on his prestige in academia and relationships with many professors in Princeton, she could win her the greatest resources.
It's like a letter of recommendation from a celebrity.
Her last name is a very, very powerful letter of recommendation, and it is the one that is commonly used in academia and does not need to be actively displayed.
In such a situation, even if you don't work hard, it won't mix badly, let alone she is a girl who is not inferior to her brother in terms of hard work ...
"The future economic model is a very promising direction. Compared with other fields, we have very little research in this field. Now it happens to be in an era of rapid development. Old theories have been difficult to adapt to new ones. Change, even though it looked very advanced at the time ... like the Star Trade Theory I said before. "
After a pause, Professor Krugman continued.
"I know the topic of her recent dissertation, which happens to be related to the recent hot alien colony fund. Whether it is applied economics or theoretical economics ~ EbookFREE.me ~ For her, It's an opportunity. "
Professor Albert: "Opportunity?"
Krugman nodded.
"An opportunity to combine theory and application and find some kind of balance in it."
"The entire economics community is using the" Tiancang Five Alien Colony Fund "as a sample to study the future social and economic activities of human civilization, and as the manager of this sample. I believe with her insight, it should not be difficult to discover What ... after all, she is the person closest to the 'truth', and even if I can learn more than she does. "
"If ... I mean, if she can summarize the laws and find something different for human socioeconomic activities after the hyperspace theory."
Facing the expression of Professor Albert's gradual surprise, Krugman said in a tone that was not joking.
"Perhaps in her lifetime, she really hopes to touch the Nobel Prize ..."
