I Am the President of the University

Photon, also known as light quantum, is the basic particle that transmits electromagnetic interaction. It is a gauge boson. It was proposed by Einstein in 1905 and officially named by American physical chemist Gilbert Lewis in 1926.

The basis of photonic chips is optical switches, reflectors, filters, and prisms. Light of different wavelengths, different phases, and different intensities run around inside to perform logical operations.

So what's the problem? The problem is that photons are closer to waves than electrons, which means that photons will not travel in the designed channels.

How to make photons, a little kid, run honestly on materials and devices to achieve optical computing.

Of course, this is easier said than done.

Professor Ren Hong’s team has been studying optical computing, but unfortunately there has been no breakthrough at all.

These days, Dai Wenyu and his senior brother often come to the laboratory to do experiments without sleeping. Recently, he had a strange idea.

So he made page after page of calculations in his notebook.

After a week of hard work, Dai Wenyu looked at the final calculated results and smiled.

"I have to show it to the teacher!" Dai Wenyu couldn't wait to greet Professor Ren Hong when he returned to the laboratory with his notebook and pen.

"Teacher, I have some ideas about optical computing!" Dai Wenyu opened his notebook excitedly and showed the results of these days to Ren Hong.

While turning it over with his hands, he murmured an explanation on the other side.

"Is this the idea you proposed?" Ren Hong frowned at first, then took Dai Wenyu's notebook with a smile, and read carefully from the first page, line by line.

When he saw the fourth page, Ren Hong was thoughtful... After reading the ninth page, he couldn't help but nodded.

It's just that... when Ren Hong saw a place on page 13, he frowned instantly and his face became serious.

Dai Wenyu, who was full of confidence on the side, felt his heart skip a beat when he saw this. Did I write something wrong somewhere?

While Dai Wenyu was uneasy, Ren Hong finally read the entire article about derivation.

He closed the notebook, handed it to Dai Wenyu, sighed deeply, and said:

"Xiao Dai, you have made great progress recently. This idea is very novel, but..."

Dai Wenyu just raised his smile and was not happy for a while when the turning point came. \b

"It's just that there is a problem with the derivation of one of your formulas on page 13, didn't you find out?" At this point, Ren Hong said seriously.

He is usually very good to his students, just like he treats his own children. But this is a normal situation. Once you are engaged in scientific research, there are no teachers, students, father and son, only a rigorous scientific research attitude!

"Ah? No!" Dai Wenyu, who was shocked, quickly opened his notebook and found the formula that Professor Ren Hong said.

He kept silent, just stared at that place, and then after a few seconds, he raised his head and argued with some persistence: "Teacher, I think the derivation of the formula here is fine!"

"Do you really think it's okay?" Ren Hong looked at Dai Wenyu and asked again.

"I...I think it's okay..." Dai Wenyu had a flash of struggle in his eyes, but in the end he still believed in himself.

Ren Hong said calmly: "According to your derivation, there is no problem, but science requires a rigorous attitude and the pursuit of perfection. Whenever there is uncertainty, multiple calculations must be made."

"You should know that the formula on page 13 is diverse. Different results will be obtained at different frequencies, but you only made one conclusion."

"I know you are right, teacher. There are many conclusions. But if we carry out the experiment at my frequency, the final experimental results will be consistent with the assumptions!" Dai Wenyu said still unwillingly.

Dai Wenyu is the student Ren Hong is most proud of and the student he most believes can inherit his legacy. Not only are people smart, but they are also diligent and humble.

It's just that maybe they haven't been hit for a long time, and some people are a little eager for success, which blinds their souls.

There is no shortage of geniuses in this world, but only those who grow up are called geniuses. Those who fail... no one will remember them.

Looking at Dai Wenyu, Ren Hong's eyes softened and he said earnestly:

"You are a person who enjoys scientific research, and you are also very smart. I hope that when you embark on the path of scientific research, you will be firm and practical every step you take. Every word and every formula you write will follow you for a lifetime. So the formulas you write should withstand the scrutiny and scrutiny of time.”

Dai Wenyu, who was a little upset at first, lowered his head when he heard the teacher's words of concern.

Some self-blame.

"Why do I still quibble even though I know the teacher is right?"

"Teacher, you are right, I was wrong." Dai Wenyu bit his lip, his eyes slightly red.

Other professors might have been disappointed and then gradually drifted away.

But Professor Ren Hong would not do this. He was like an old father, slowly guiding him to discover his mistakes.

"Xiao Dai, can you think of me like this..." Just halfway through Ren Hong's words, the door of the laboratory was pushed open and a person walked in.

Professor Ren Hong was stunned for a moment when the other party had already walked beside him.

"Professor Ren, classmate Xiao Dai, what are you discussing so intensely?" Chen Hao asked with interest.

Looking at the two of them again, one lowered his head as if he had been bullied, and the other had a stiff face.

"Xiao Dai mentioned an idea of ​​optical computing to me. I looked at the derivation steps and they are pretty good, but there are some places that are not very rigorous. Principal Chen, why don't you take a look?"

"Okay, let me take a look." Chen Hao readily took the notebook and flipped through it with relish.

However, Ren Hong came to his senses at this time, shook his head and said, "I forgot that Principal Chen, you are in the computer field. You should not be involved in this field."

"In the field of semiconductors, I actually know a little bit about it." Chen Hao looked at the notebook at a glance and said,

It only took Professor Ren Hong 1/4 of his time to read the entire article.

"Did classmate Xiao Dai write this idea?" Chen Hao returned the notebook to Ren Hong and looked at him and asked.

"Yes, it was written by Xiao Dai." Ren Hong was a little confused. Did Principal Chen understand it?

Unlikely? Such a short time... is a bit exaggerated.

Pretending to understand if you don’t understand?

Thinking of this, Ren Hong frowned slightly, and his evaluation of Chen Hao in his heart couldn't help but drop a little.

"Xiao Dai has made great progress, and he is very innovative." Chen Hao first praised, and then quietly threw a skill at Dai Wenyu.

"System, use the [Insight] skill on Dai Wenyu!"

The moment the voice fell, a message appeared on the system panel in front of Chen Hao.

"Name: Dai Wenyu

Alignment: Friendly

Potential: 92 (top talent)

Ability: Electronics Research, Chemistry, Materials Science, Optics The biggest changes are in electronics and optics. The former has increased by 2 points compared with the initial recognition, and the latter has directly increased by 4 points. As for other scientific research and materials science, they have also increased by 1 point each.

After all, the research institutes produced by the system have the attribute of increasing scientific research capabilities, and with Dai Wenyu's talent here, he is still so diligent and studious, so it is understandable that his level has risen quickly.

However, this made Chen Hao even more excited!

Professor Ren Hong wants to stay, and even more so, classmate Xiao Dai!

Dai Wenyu felt Chen Hao's blazing eyes looking at him. He was frightened and took two steps back with a panic on his face. "Chen, Principal Chen, are you okay?"

"Ahem, I'm fine, maybe my eyes are tired." Knowing that he had lost his composure, Chen Hao quickly corrected his attitude, and then a smile gradually appeared, "I would like to express my humble opinion on the derivation written by Xiao Dai."

"There are indeed errors in formula derivation in Xiao Dai's idea of ​​light calculation, mainly on pages 8, 11, 13, and 15. Where are the mistakes? I will briefly post them. My own opinion..."

Ren Hong didn't take it seriously when he heard what he said before, he just thought it was an outsider making a joke.

After all, I have been deeply involved in chips for ten or twenty years, and I am considered one of the authorities in the field of chip design in China. Why not be as good as a person in his twenties who has just graduated with a Ph.D.?

Just hearing what happened later, Ren Hong's hands and feet gradually became cold! \b

Subconsciously swallowed a ball of saliva.

"Okay, I've finished speaking, that's about it. Professor Ren Hong, if you have anything to add, you can tell me, just treat it as scientific dialectics." Chen Hao looked at Ren Hong and smiled brightly.

Ren Hong did not speak for the first time, but fell into silence.

Almost half a minute later, Ren Hong raised his head and looked at Chen Hao, and asked cautiously with an uncertain tone:

"Principal Chen, are you an expert in the field of materials?"
