Chapter 130 Physics Applied Technology

In the afternoon, the students met a new professor who was responsible for optics.

When he first walked in, Wu Bin felt the aura of a strong man, because one of his eyes... had an indescribable sharpness, and when he was looked at, he felt like he was being stared at by an eagle. .

Later, I heard from him that his left eye had been damaged during an optical experiment, and his pupil contraction was somewhat different from ordinary people.

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

‘Boss, boss. ’

In addition, the content of this great professor’s lecture is also unparalleled...Quantum optics! This is really the course that Wu Bin feels most confused about right now. Only when the professor said that the laser light field obeys the classic Maxwell electromagnetic equations did he have a little understanding.

The person in charge of teaching thermal science is Song Nanfeng, a professor from the University of Science and Technology who met Wu Bin backstage at the award ceremony. He is considered by Wu Bin to be one of the best lecturers. His so-called explanation of profound things in simple terms is fully reflected in him.

In addition, his ability to formulate questions is also very strong. Just listing a question on the blackboard is enough to make the young talents below think about it.

Therefore, when this professor is in class, the rate of people looking up is the highest.

But there was one thing about this professor that made Wu Bin very annoyed or flattered... that is, every time after class, the professor would come to him privately to talk about Hua University of Science and Technology.

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

"Did you go to the camera lecture yesterday?" Song Nanfeng asked after pouring a glass of water for Wu Bin.

"Thank you, teacher." Taking the water glass with both hands, Wu Bin nodded and replied, "Yes, but there doesn't seem to be much practical information. It seems to be mainly for recruiting students."

"Tsk, tsk." Song Nanfeng shook his finger, "Not only that, but actually asking you to attend this symposium, I also want you to know another point, that is, learning physics well can make a lot of money~"

"..." Wu Bin was stunned, thought for a moment and asked: "Don't you say that academics should be more pure?"

"You just don't need to eat?"

"..."

Wu Bin was speechless.

"It seems that you also have a deep misunderstanding of physics." Song Nanfeng casually took out a piece of white paper and continued: "Among all disciplines, there are few research fields as broad as physics. Look, As small as atoms, nuclei, electrons and quarks, as large as galaxies and the universe, as fast as attoseconds and as slow as tens of billions of years, these physics are all involved, do you know what this means?"

"Ten... Tiger Balm?"

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

‘Isn’t this just snake oil…’ Wu Bin didn’t dare to complain.

Seeing that Wu Bin was silent, Song Nanfeng continued, "When it comes to physics, most people's first reaction is often Einstein and his theory of relativity. They always feel that this is a theoretical rather than practical science. As a result, many parents now have concerns about their children choosing a physics major, even some students. This is completely a misunderstanding!"

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

There's nothing he can do about it. He learned that now he spends all his time playing pinball, trucks, and satellites. It's all impractical no matter how you look at it.

This reminded him of what Cai Guoping said to him. High school knowledge is only the foundation, and there is still a long way to go before applying what you learn. That's why he took him to the electronic technology exhibition, although he still didn't find it after watching it. Just clear the direction...

Seeing Wu Bin nodding, Song Nanfeng couldn't help but pat his forehead and sighed: "Tsk, today's teaching is too much about learning for the sake of learning." He shook his head again, "Although it was like this before."

"Hey, Wu Bin, tell me first, why do you think studying physics is for you?"

"Exploring the nature of the world or universe?"

After hearing this, Song Nanfeng first smiled, then reached out and patted Wu Bin on the shoulder, "Hey, I'll give you a free lesson to let you understand how important physics is in the applied field."

After saying that, he started writing on the white paper.

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

"I don't want to brag to you, but physics has already penetrated into most applied sciences. Physics graduates are also welcomed by many applied industries." He shook the white paper and said, "Here, take these Let’s give an example.”

"Finance?" Wu Bin looked confused.

Seeing Wu Bin's incomprehensible look, Song Nanfeng smiled proudly, "Let me list some data for you first." Then he wrote on the paper as he spoke, "As far as the statistics of our graduates from the University of Science and Technology are concerned, now in IT 28% work in industry, 20% work in semiconductor and traditional industries, and 13% work in finance, trade, commerce, and consulting.”

"Why is this happening?" Seeing that Wu Bin didn't say anything, Song Nanfeng asked himself.

"Today, when interdisciplinary sciences increasingly occupy an important position, it is difficult to meet society's demand for comprehensive talents by only learning knowledge in a single major."

"Comprehensive ability is competitiveness!" Song Nanfeng emphasized.

“In this social background, physics graduates who have a solid mathematical foundation, excellent learning ability, and can quickly absorb knowledge in various fields are increasingly favored by all walks of life, so more and more physics graduates are favored by all walks of life. integrated into all walks of life.”

"Oh~" Wu Bin nodded as if he understood.

"Tsk, let me give you some specific examples." Song Nanfeng knew from Wu Bin's expression that he didn't fully understand yet, "The 21st century is the century of information. Have you heard this sentence before?"

"Um."

"Then what is the cornerstone of information technology? That is large-scale integrated circuits and storage devices, which very much need the help of physics."

Raising a finger, Song Nanfeng continued: "Let's take a storage device as an example. The current hard disk principle is the GMR effect, which is giant magnetoresistance. Simply put, by changing the direction of the magnetic field, the giant magnetoresistance structure The resistance changes significantly and has two steady states, so..."

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

"Hmm...that's what I mean, why, are you also interested in informatics?"

"Well, I'm learning programming language recently."

Wu Bin felt a little inexplicably excited at the moment. It was obvious that he thought the two majors were not closely related, but in fact they were closely related.

This is just like what he said in his acceptance speech at the physics competition. When some knowledge learned in other fields is mentioned again when he studies physics, there is always an inexplicable pleasure.

Yes, it's really enjoyable.

PS: The third update, it feels so good not to have to finish writing before 12 o'clock... I can probably write another chapter.
