Scholar’s Starry Sea

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

When he first walked in, Wu Bin felt a powerhouse breath, because one of his eyes...has an inexplicable sense of sharpness. Kind of the feeling of being stared at by an eagle.

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

Wu Bin couldn't help feeling deeply after listening.

'Big guy, big guy. '

In addition, the content of this big professor's lecture is also very big...Quantum optics! This is really the course that Wu Bin feels the most when he hears it now. Only when this lecturer said that the laser light field complies with the classic Maxwell electromagnetic Simultaneous Equations, did he have that understanding.

The person responsible for teaching heat is Song Nanfeng, a professor of University of Science and Technology who had a relationship with Wu Bin at the backstage of the award ceremony. He is considered one of the best lecture professors Wu Bin thinks. The so-called in-depth explanation is vividly and thoroughly reflected in him.

In addition, his ability to make questions is also very strong. Just listing a question on the blackboard is enough to make the young talents underneath want to break their heads.

So this professor had the highest rate of head-up when he was in class.

But there is one thing that this professor makes Wu Bin very painful or flattered...that is, every time the professor finishes his class, he has to find him in private at the University of Science and Technology. The sky is blowing in disorder, there is in the sky, and there is nothing in the underground.

Today is no exception. As soon as the thermal class was over, Wu Bin was brought to his office by the professor.

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

"Thank you teacher." After taking the water glass 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 enrollment."

"tsk tsk. "Song Nanfeng shook his finger, "More than that, I actually want you to listen to this seminar, but you also need to know another point, that is, learning Physics well is very profitable~"

"..." Wu Bin was stunned and thought for a while to ask: "Isn't it said that academics should be purer?"

"I don't need to eat purely?"

"..."

Wu Bin is speechless.

"It seems that you also have a deep misunderstanding of Physics." Song Nanfeng took a blank sheet of paper and said: "In all disciplines, there are few research fields like Physics. Extensive, you see, as small as atoms, nuclei, electrons and quarks, as large as galaxies and universes, it can be as fast as an attosecond, and slow as slow as tens of billions of years. These Physics are all involved. Do you know what this means? ?"

"Ten thousand... ten thousand gold oil?"

"Um...No" Song Nanfeng shook his head, "It should be said that Physics and related disciplines are the basics for exploring the structure and movement of matter. The most cutting-edge discipline of law is the foundation and source of scientific discovery and technological innovation."

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

Seeing that Wu Bin didn’t speak, Song Nanfeng went on to say, “When it comes to Physics, most people’s first reaction is often Einstein and his theory of relativity. I always feel that this is a theoretical one. Rather than practical science, many parents are now worried about their children choosing Physics as a major, even some students. This is a complete misunderstanding!"

After listening to Song Nanfeng, Wu Bin couldn’t help. nodded, because he is also a member of "even some students".

There is no way. He has learned that all day is pinball, truck, satellite, all kinds of impractical.

This reminded him of what Cai Guoping said to him. High school knowledge is only a basis, and there is still a long way to go before the application of what he learned. This led him to see the electronic technology exhibition, although He still didn't find his direction after reading it...

Seeing Wu Bin nodded, Song Nanfeng couldn't help but patted his forehead, sighed then said: "Hey, the current teaching is too learning for learning. "I shook my head again, "Although it was like this before."

"Hey, Wu Bin, first tell me, what do you think is learning Physics for?"

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

Song Nanfeng smiled after listening, and then extended the hand patted Wu Bin's shoulder, "Now, I will give you a free lesson to let you understand the application of Physics. How important is it?"

After speaking, I wrote on the white paper.

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

"Don’t tell you the amazing, Physics has already penetrated most of the applied sciences. Now, Physics graduates are also welcomed by many application industries." He shook the blank paper, "Hey, just take these as examples."

"Finance?" Wu Bin looked confused. force.

Looking at Wu Bin's inexplicable look, Song Nanfeng laughed a little proudly, "I will list you some data first." Then he said and wrote on the paper, "Just our University of Science and Technology. According to the statistics of graduates, 28% now work in the IT industry, 20% in Semiconductor and traditional industries, and 13% in finance, trade, business, and consulting."

"Why is this happening? What?" Seeing Wu Bin didn't speak, Song Nanfeng asked and answered himself.

"Today, when interdisciplinary sciences are becoming more and more important, it is difficult to meet the society's demand for comprehensive talents only by 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. Therefore, Physics is more and more integrated into all walks of life."

"Oh~" Wu Bin is nodded who seems to understand but not understand.

"Hey, I'm going to give you some more concrete examples." Song Nanfeng knew Wu Bin's facial expressions that he hadn't fully understood, "The 21st century is the century of information. I always listen to this sentence. Pass it?"

"en. "

"What is the cornerstone of information technology? That is large-scale integrated circuits and storage devices, which require Physics Help."

Put up a finger, Song Nanfeng continued: "Take the storage device as an example. The principle of the current hard disk is the GMR effect, which is the giant magnetoresistance. In short, it is By changing the direction of the magnetic field, the resistance of the giant magnetoresistive structure will change significantly, and there will be two steady states, so..."

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

"Well...that's what it means, why are you also interested in informatics?"

"Well, I am learning programming languages ​​recently."

Wu Bin The mood at the moment was a bit inexplicably excited. It was obviously because he felt that the two majors were not related, but in fact they were closely related.

This is just like his acceptance speech at the Physics competition. When the knowledge learned in other fields is mentioned again in his study of Physics, there is always an inexplicable joy.

Yes, this is really pleasant.

PS: Third, I don’t have to finish writing before 12 o’clock. It feels so good... I can probably write a chapter.
