"The structure of DNA, the basis of human genome engineering, was determined by the physical method of X-ray diffraction."

"The problem of protein folding is an important and unsolved problem in molecular biology."

"The significance of this question is to solve the problem of how proteins express life information, which has a very important role in solving major diseases such as Parkinson's disease and mad cow disease."

"Traditional biological approaches to this problem have huge limitations. On the contrary, scientists have made many major breakthroughs using physical methods such as thermodynamics and kinetics. ”

In the process of listening, Wu Bin wrote down the key points in Song Nanfeng's words one by one, especially for some problems that have not been completely solved although breakthroughs have been made......

'Hey, cool batch! ’

Of course, the problem of stumping so many people in the world must be quite difficult, and now he definitely doesn't even have the ability to study, but this does not prevent him from generating a huge motivation to learn!

"Hey, what are you smirking at?" Song Nanfeng patted Wu Bin and shouted, "I'm about to drool you." ”

After hearing this, Wu Bin quickly wiped his mouth, coughed awkwardly and said, "I didn't think about anything, I just think that physics is really interesting, and I can use anything." ”

"That's for sure, I'm just giving you a typical example." Song Nanfeng shook the water cup in his hand as he spoke, and then pointed to the vortex formed by the hot water in the cup, "In recent years, as the focus of biological research has gradually shifted from macroscopic organisms to microscopic molecular scales, and from qualitative description to quantitative analysis, biophysics is like the center of this vortex, rolling more and more things in. ”

Looking at the whirlpool in the cup, Wu Bin was thoughtful.

"So physics has a lot of experience in dealing with complex problems quantitatively, so many biological problems can be explained from the perspective of physics?"

Luo Wenmin, who was sitting on the side, heard Wu Bin's words, squinted his eyes and nodded, "The children can be taught, the children can be taught." ”

Song Nanfeng also nodded with the same satisfaction, and continued to talk to Wu Bin about the outstanding contributions of physics in materials science, electronics and chemistry, and when he finished speaking, the lunch break was almost over.

But Wu Bin was obviously still unsatisfied, so he took advantage of the remaining time and hurriedly asked the question that he was confused about at the beginning.

"What about finance? Why can finance also use physics? ”

"Oh~ you still remember." Song Nanfeng smiled, changed his sitting posture and thought about it slightly, "In your opinion, finance seems to be a discipline that is completely incompatible with physics, right?" ”

Wu Bin nodded without hesitation, he couldn't think of anything to do with physics and finance, if Song Nanfeng told him that what physics produced would have economic benefits, he would definitely be disappointed.

"Well, listen up, in fact, theoretical physics and finance are not only related, but also have a closer relationship than the majors I told you before."

Looking at Wu Bin and Wu Bin's surprised expressions, Song Nanfeng also knew that he had whetted the appetite of this kid, so he began to explain with a smile.

"First and foremost, theoretical physics and finance have a lot in common, have you ever learned about economics?"

Wu Bin shook his head.

"Well, then let me tell you a concept first, that is, socio-economic activities are a system composed of a large number of individual events, can this be understood?"

Wu Bin understood a little, and nodded clearly.

"Well, then, again, statistical physics is about a large number of particle systems."

"This ...... Can this also be related? Wu Bin couldn't help but complain.

"Don't worry." Song Nanfeng shook his head, "In the financial market, there are many individual events and behaviors that are often driven by unpredictable people's minds, and in this regard, physics is similar, and there are also completely uncertain in quantum physical systems, and even predictions cannot predict the ups and downs of the Dao. ”

Hearing this, Wu Bin was still confused, and even made him interested in economics.

"But the difference between the two is that physics has a way of studying this phenomenon, and guess what happens in this case?"

This time, Song Nanfeng didn't have Wu Bin's appetite, and directly announced the answer.

"This led to a physicist discovering that the theory of quantum electrodynamics could be used to analyze changes in stock options."

"Poof!" Wu Bin's mouth opened, "This...... That's fine??? ”

"I can't think of it, hahaha." Wu Bin's exaggerated expression amused Song Nanfeng at once, and he laughed for a while before continuing.

"I'm not going to lie to you, in fact, some of the behemoths in the financial markets now, such as Swiss banks and Wall Street securities firms, have hired a group of PhDs in high-energy physics and theoretical physics for more than a decade. Even the physics department at Columbia University has Wall Street job advertisements on the billboards. ”

"Thing...... Physics is awesome! ”

After listening to these contents, Wu Bin's heart really turned up a monstrous wave at this moment, and the physics that he thought he was about to grasp in his hand appeared on the other side in a more distant way with a different attitude, which made him fanatical and fascinated again.

At this time, Song Nanfeng looked at Luo Wenmin on the side and asked politely: "Professor Luo, I remember that there are several outstanding graduates of Peking University who are thriving in the financial industry, right?" ”

Luo Wenmin was stunned for a moment after hearing this, and he didn't understand why Song Nanfeng suddenly threw this hydrangea to himself, and paved the way for a long time, but B gave him Peking University to pretend, how embarrassing is this?

After thinking about it, Luo Wenmin suddenly understood, it is estimated that the two of them were fighting with a white face just now, which damaged the image, so it is time to show grace.

So Luo Wenmin was not hypocritical, nodded and said: "There are a few, it should be the class of 96, at that time, there were three graduates, who went to Stanford, North Carolina, and the University of California, respectively, all of them have double doctorates in physics and finance, and they are good at applying the mathematical skills behind them to financial research." ’

"One of the most famous ones I remember is that Huang Ming, when he graduated, he was robbed by several universities such as Chicago Business School, Harvard Business School, Wharton School of the University of Pennsylvania and MIT Sloan School of Business, and they all wanted to ask him to teach, right?"

After speaking, he added: "It seems that he has been named the 'Most Promising Doctor of the Year' by the United States?" ’”

"Professor Song knows better than I can remember, there is such a thing." Luo Wenmin nodded with a smile, and then replied politely, "But there are many talents like HKUST." ”

But Song Nanfeng shook his head after hearing this, "There are not a few of them, our students at the University of Science and Technology are still relatively rigid, they like to stumble on physics as a major, and they don't like to touch anything else, so I'm so sad." ”

‘MMP…… I'm waiting here! Luo Wen was so angry that he almost scolded, this set is too deep!
