In the afternoon, the students met a new professor who was in charge of optics.

As soon as he walked in, Wu Bin felt the aura of a strong man because of one of his eyes...... There is an indescribable sense of sharpness, and when you are watched, you will feel like you are being stared at by an eagle.

Later, I heard him say that his left eye had been damaged in optical experiments, and his pupil constriction was a little different from that of ordinary people.

Wu Bin couldn't help but sigh in his heart after hearing this.

'Big guy, big guy. ’

In addition, the content of this big professor's lecture is also very big...... Quantum Optics! This is really the lesson that Wu Bin feels the most foggy when he hears it now, and it is only when this lecturer says that the laser light field obeys the classical Maxwell's electromagnetic equations, he can be regarded as having a little understanding.

He is one of the best lecturers in Wu Bin's opinion.

In addition, his ability to solve problems is also very strong, and listing a question on the blackboard is enough to make the young talents below want to break their heads.

So when this professor is in class, the head up rate at the bottom is the highest.

But there is one thing that this professor makes Wu Bin very painful or flattered...... That is, every time the professor finishes class, he has to come to him privately to Amway Huake University, which is really blowing, there is something in the sky, and there is nothing in the ground.

Today is no exception, as soon as the hot class ended, Wu Bin was pulled into his office by the professor again.

"You went to the camera's lecture yesterday, right?" Song Nanfeng asked after pouring a glass of water for Wu Bin.

"Thank you, teacher." After taking the water cup with both hands, Wu Bin nodded and replied: "Well, but there doesn't seem to be much dry goods, it seems that it is mainly for recruitment." ”

"Tsk." Song Nanfeng shook his fingers, "Not only that, in fact, let you listen to this symposium, but I also want you to know another point, that is, learning physics well is very profitable~"

"......" Wu Bin was stunned, thought for a while and asked: "Didn't you say that academics should be pure?" ”

"You don't have to eat?"

“……”

Wu Bin was speechless.

"Looks like you have a deep misunderstanding of physics." Song Nanfeng casually pulled out a blank piece of paper, and then said: "In all disciplines, there are few fields of study as wide as physics, you see, from atoms, nuclei, electrons and quarks, to galaxies and the universe, fast to attoseconds, slow to tens of billions of years, these physics are involved, do you know what this means?" ”

"Wan ...... Factotum? ”

"Hmm...... No," Song Nanfeng shook his head, "It should be said that physics and related disciplines are the most cutting-edge disciplines to explore the basic laws of material structure and motion, and are the foundation and source of scientific discovery and technological innovation. ”

"Isn't this a panacea......" Wu Bin didn't dare to complain.

Seeing that Wu Bin didn't speak, Song Nanfeng continued, "When it comes to physics, most people's first reaction is often Einstein and his theory of relativity, and they always feel that this is a theoretical rather than practical science. ”

After listening to Song Nanfeng's words, Wu Bin couldn't help but nodded, because he was also one of the "even some students".

There's no way around it, he's learned to be pinball, trucks, satellites all day long, no matter how you look at it, it's all kinds of impractical.

This reminded him of what Cai Guoping said to him, high school knowledge is just a foundation, and there is still a long way to go before learning to apply, so he took him to see the electronic technology exhibition, although he still didn't find the direction after reading it......

Seeing Wu Bin nodding, Song Nanfeng couldn't help but pat his head and sighed: "Tsk, the current teaching is too much for learning." Shaking his head again, "Although it used to be like this." ”

"Hey, Wu Bin, let's talk about it first, what do you think is the purpose of studying physics?"

"Exploring the nature of the world or the universe?"

Song Nanfeng smiled at first, then stretched out his hand and patted Wu Bin's shoulder, "Now, I'll give you a free lesson to let you understand how important physics is in the application field." ”

After saying that, he wrote on a blank piece of paper.

[Materials] [Electronics] [Chemistry] [Biology] [Finance]

"I won't brag to you, physics has long been infiltrated into the vast majority of applied sciences, and physics graduates are also welcomed by many applied industries." As he spoke, he shook the white paper, "Well, let's take these as examples." ”

"Finance?" Wu Bin looked confused.

Looking at Wu Bin's inexplicable appearance, Song Nanfeng smiled a little proudly, "I'll give you a list of data first." "According to the statistics of our HKUST graduates, 28% are now working in the IT industry, 20% in semiconductors and traditional industries, and 13% in finance, trade, business, and consulting. ”

"Why is this happening?" Seeing that Wu Bin didn't speak, Song Nanfeng came to ask and answer himself.

"Today, with interdisciplinary science occupying an increasingly important position, it is difficult to meet the society's demand for comprehensive talents by learning only the knowledge of a single specialty."

"Comprehensive ability is competitiveness!" Song Nanfeng emphasized.

"In this social context, physics graduates with a solid foundation in mathematics and physics, excellent learning ability, and can quickly absorb knowledge in various fields are increasingly favored by all walks of life, so physics is increasingly integrated into all walks of life."

"Oh~" Wu Bin nodded as if he didn't understand.

"Tsk, I'm giving you some specific examples." Song Nanfeng looked at Wu Bin's expression and knew that he hadn't fully understood, "The 21st century is the century of information, have you always heard this sentence?" ”

"Hmm."

"So what is the cornerstone of information technology? That's large-scale integrated circuits and storage devices, and they need the help of physics. ”

Raising a finger, Song Nanfeng continued: "Let's take storage devices as an example, the current principle of hard disks is the GMR effect, that is, giant magnetoresistance. To put it simply, by changing the direction of the magnetic field, the resistance of the giant magnetoresistive structure will change significantly, and there are two steady states, so as to ......"

"Record 0 and 1!?" Wu Bin clapped his hands and understood!

"Hmm...... In that sense, why are you also interested in informatics? ”

"Well, I've been learning programming languages lately."

Wu Bin's mood at the moment was a little inexplicably excited, obviously because he felt that the two majors had little to do with each other, but in fact they were closely related.

Just like his acceptance speech at the physics competition, there is always an inexplicable joy when some of the knowledge he has learned in other fields is mentioned again when he studies physics.

Yes, it's really pleasant.

PS: The third update, it feels good that you don't have to finish writing before 12 o'clock...... I can probably write a chapter.
