Xueba's Sea of ​​Stars

Chapter 130 Physics Applied Technology
In the afternoon, the students met a new professor who was in charge of optics.

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

Later, I heard from him that his left eye was damaged in the optical experiment, and the degree of pupil constriction was somewhat different from that of ordinary people.

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

'Big guy, big guy. '

In addition, the content of the professor's lectures is also incomparable...quantum optics!This is really the course that Wu Bin feels the most in the fog when he hears it now. Only when the lecturer said that the laser light field obeys the classic Maxwell's electromagnetic equations did he have a little understanding.

The person in charge of teaching heat science is Song Nanfeng, a professor at the University of Science and Technology who met Wu Bin at the backstage of the award ceremony. He is one of the best lecturers in Wu Bin's opinion.

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 want to break their heads.

Therefore, when this professor is in class, the rate of raising his head is the highest.

But there is one thing about this professor that makes Wu Bin very sad or flattered... that is, every time the professor finishes his class, he would come to him privately to visit Huake University.

Today was no exception. Just after the heat course was over, Wu Bin was dragged into his office by the professor again.

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

"Thank you, teacher." After taking the water glass with both hands, Wu Bin nodded and replied, "Yes, but there don't seem to be many dry goods. It seems that they are mainly for recruiting students."

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

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

"Just don't need to eat?"

"..."

Wu Bin was speechless.

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

"Wan... panacea oil?"

"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 the structure and motion of matter, and are the foundation and source of scientific discoveries and technological innovations."

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

Seeing that Wu Bin was silent, Song Nanfeng went on to say, "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 a practical science. What happened is that many parents now have many concerns about their children's choice of physics major, even some students are, this is a complete misunderstanding!"

After listening to Song Nanfeng's words, Wu Bin couldn't help but nodded, because he was also a member of "Lian Some Students".

There's no way around this, he learned that now it's all about pinballs, trucks, and satellites, which are all impractical no matter how you look at it.

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

Seeing Wu Bin nodding his head, Song Nanfeng couldn't help but patted his forehead and sighed: "Tsk, the current teaching is too much for the sake of learning." He shook his head again, "Although it used to be like that."

"Hey, Wu Bin, tell me first, what do you think the purpose of studying physics is?"

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

Song Nanfeng first smiled after listening, and then stretched out his hand to pat Wu Bin on the shoulder, "Hey, I will give you a free lesson, so that you can understand how important physics is in the field of application."

After speaking, he wrote on the white paper.

【Materials】【Electronics】【Chemistry】【Biology】【Finance】

"Not to brag, physics has already penetrated into most of the applied sciences, and physics graduates are also welcomed by many applied industries." He shook the white paper, "here, just take these Let me give you an example."

"Finance?" Wu Bin was confused.

Seeing Wu Bin's inexplicable appearance, Song Nanfeng smiled smugly, "Let me list some statistics for you first." Then he wrote on the paper while talking, "As far as the statistics of our USTC graduates are concerned, the current IT Industry jobs accounted for 28%, semiconductor and traditional industries accounted for 20%, and finance, trade, business, and consulting accounted for 13%.

"Why did this happen?" Seeing that Wu Bin didn't speak, Song Nanfeng asked himself a question.

"Today, when interdisciplinary science is increasingly playing an important role, it is difficult to meet the society's demand for comprehensive talents by only learning a single professional knowledge."

"Comprehensive ability is competitiveness!" Song Nanfeng emphasized.

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

"Oh~" Wu Bin nodded half understanding.

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

"Ah."

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

Putting up a finger, Song Nanfeng continued: "Take storage devices as an example. The principle of the current hard disk is the GMR effect, which is the giant magnetoresistance. Simply put, by changing the direction of the magnetic field, the structure of the giant magnetoresistance The resistance changes significantly, and there are two steady states, so that..."

"Record 0 and 1!?" Wu Bin clapped his hands, enlightened!
"Well... that's what it means, why, you are also interested in informatics?"

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

Wu Bin is feeling a little inexplicably excited at the moment, obviously because he thinks the two majors have little to do with each other, but in fact they are closely related.

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

Yes, it's really enjoyable.

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