On the morning of January 19, the office of the director of the building was collided.

Su Zhe sat at his desk and looked at the launch plan of the Xuanwu Project space probe on the 22nd.

In the Xuanwu program, 3,000 domestic SS-defense system subsystems are the main body, supplemented by a small number of space probes.

There are a total of 36 probes to be launched in this launch plan, which are carried by the same rocket, that is, 36 satellites in one rocket.

Of the thirty-six probes, eighteen are deployed in low orbit and another eighteen are in high orbit.

The purpose of launching these probes is to extend the detection range of the SS-defense system.

Without these probes, the SS-Defense system deployed on the ground would have an effective detection range of 10,000 kilometers from the ground, and with the addition of these space probes, the effective detection range can be extended to 300,000 kilometers.

However, considering that these detectors were manufactured in a hurry, their lifespan is very short, only half a year.

He looked at the parameters of the rocket carrying these probes, and his mind was on the heavy photon aerospace engine.

Rockets that use chemical energy are too inefficient.

For example, the 36 probes to be launched this time should not only consider the performance of the probe, but also the mass and volume of the probe when designing the probe, and the result can only be compromised.

If there is a more powerful vehicle, then just consider the detector.

Then there is the experimental space power station built in space by the scientific research team of academician Zhao Guoan of Northwest University of Electronic Technology.

In order to build this space power station in synchronous orbit, it was launched three times in just one month, and a total of 36 tons of supplies were transported.

The capacity of one shipment is only twelve tons.

Truth be told, this capacity can't meet the current demand.

To change the status quo, heavy photon aerospace engines are a very good direction.

Just thinking about it, I saw Fan Xiaoming walk into the office.

"Look what! It's time. Fan Xiaoming reminded, "I've heard that the president has invited many domestic physics elders to participate in your graduation defense, so you have to be prepared." ”

Su Zhe looked at the time and stood up, and said, "A lot? How many can there be? ”

With that, the two left the director's office.

"More than five hundred!" Fan Xiaoming gestured with his hand.

"Isn't it! So much! Su Zhe was surprised.

"The principal is also ruthless, and he invited so many elders." Fan Xiaoming said, "That's the graduation defense!" It's all about speeches. ”

“……”

The two talked as they walked, and the five assistants Zong Lanyue and Liu Fen followed Su Zhe and Fan Xiaoming downstairs.

"Ma Ping! Didn't you go to the top floor of the west building of the library last night, and all the physics elders in China came, just to participate in my boss's graduation defense. Bi Yuankui whispered with some pride.

"Go!" Ma Ping nodded excitedly, "To be honest, our big boss is the best boss in the physics world." ”

“……”

Su Zhe and his entourage of seven got into a patrol car.

After a while, the patrol car stopped in front of the library.

Instead of taking the internal elevator in the West Building, the seven people took the spiral staircase between the East and West Buildings to the top floor of the West Building.

Su Zhe walked into the No. 1 lecture hall and burst into applause.

Principal Xu Zhengping led him directly to the podium and introduced him excitedly.

Soon, the principal Xu Zhengping stepped down from the podium and gave up the podium to Su Zhe.

Su Zhe looked at the people in the lecture hall, and after a few words of greeting, he went directly to the topic.

Graduation Defense!

He first explained the paper "High-power Solar Cable Transmission Technology".

At the beginning, he explained the principle of high-power light energy wired transmission.

Very simple to say, the principle of high-power light energy wired transmission is very simple, which is similar to the propagation of optical signals by optical fibers.

The difference is that the energy of the optical signal propagated by the optical fiber is very, very low.

Naturally, the materials are also different.

In the whole process, the first thing to do is to convert other different forms of energy at point A, the most typical is to convert electrical energy into light energy, and then send light energy to point B through a special optical cable like an optical fiber, and convert light energy into electrical energy at point B.

In the process of transmission, the energy consumption is far less than the consumption of electrical energy transmission, and the transmission of light energy only requires a fiber optic cable.

When necessary, fiber optic cables that transmit light energy can transmit not only energy, but also information.

Su Zhe explained the principle of wired transmission of high-power light energy, and then explained the carrier of high-power light energy, optical cable.

From materials to structure, and then to manufacturing processes.

After saying this, we talked about the electro-optical conversion device and the photoelectric conversion device at both ends of the optical cable.

As with optical cables, materials, structures, and manufacturing processes are mentioned.

However, what Su Zhe said is all general, and there is no specific introduction.

In his opinion, it would be good to be able to introduce it in general, but it would be stupid to be specific.

After introducing the paper "High-power Solar Energy Wired Transmission Technology", the lecture hall resounded with warm applause.

Then came the Q&A session.

The elders are very positive, one question after another.

Su Zhe was also very straightforward, and he answered everything he could.

After the question-and-answer session, Su Zhe made a brief summary, and then the graduation defense at the undergraduate level ended.

The time also came to twelve o'clock at noon.

After lunch, Su Zhe went back to the apartment to rest, but these elders did not, and came to the No. 1 lecture hall to discuss.

The elders attach great importance to the paper "High-power Solar Cable Transmission Technology", because everyone knows the importance of this paper.

It was two o'clock in the afternoon.

Su Zhe began to explain his master's thesis "Microscopic Principles of Electromagnetic Wave Mutual Conversion".

The paper "Microscopic Principles of Electromagnetic Wave Interconversion" was written on the basis of the ZGZ-atomic vibration model and the spectroscopy of matter.

It deeply explores the principle of mutual conversion of electromagnetic waves of different wavelengths.

Relatively speaking, the paper "Microscopic Principles of Electromagnetic Wave Interconversion of Electromagnetic Waves" is the most important of the three papers of the bachelor's, master's and doctor's degrees.

Whether it is the paper "High-power Solar Energy Wired Transmission Technology" or the paper "Theoretical Basis of Heavy Photon Aerospace Engine", it will involve the mutual conversion of electromagnetic waves.

Su Zhe explained the paper for three hours, plus an hour of questioning and summarizing, and the paper ended at six o'clock in the evening.

After it was over, Su Zhe and the others came to the cafeteria for dinner, and it started again at seven o'clock.

Su Zhe finally explained the paper "Theoretical Basis of Heavy Photon Aerospace Engine".

Compared with the concept of the heavy photon aerospace engine mentioned in the paper "On the Manipulation of Atoms by Electromagnetic Waves", the paper "Theoretical Basis of the Heavy Photon Aerospace Engine" elaborates the principle and structure of the heavy photon aerospace engine.

When Su Zhe explained the paper "The Theoretical Basis of Heavy Photon Aerospace Engine", the elders listened very carefully.

As we all know, the heavy photon aerospace engine is epoch-making, and once it is realized, it will no longer be a dream for mankind to fully enter space.

Speaking of which, the principle of heavy photon aerospace engines is not too difficult.

The core principle is the ZGZ-atomic vibration model, in which atoms in a specific state emit heavy photons after absorbing electromagnetic waves of a specific wavelength.

In the process of releasing heavy photons, the atoms of an atom gain kinetic energy.

For the heavy photon aerospace engine, Su Zhe gave two sets of design schemes.

First, electrical energy is converted into light energy, and then the light energy is converted into electromagnetic waves of a specific wavelength to attack atoms in a specific state, thus generating heavy photons.

The second is to use light energy directly, eliminating the need to convert electrical energy into light energy.

By 11 p.m., the third dissertation defense was over.

President Xu Zhengping also symbolically solicited the opinions of all the elders present, and finally all the elders unanimously agreed that Su Zhe's three theses were defended with a master's degree and a doctorate.

Just as Su Zhe was about to step down from the podium and go back to sleep, Assistant to the Principal Han Li, Fan Xiaoming, who sat down on the stage, invited him to the podium.

Principal Xu Zhengping issued letters of appointment to Su Zhe and Fan Xiaoming under the witness of a group of elders.

After the end, Su Zhe and Fan Xiaoming left the No. 1 lecture hall, and they walked a distance of dozens of meters, and the principal Xu Zhengping chased after them.

"Headmaster! What's the matter with you? Su Zhe asked with a letter of appointment in his hand.

Fan Xiaoming also looked at Xu Zhengping curiously.

"Here's the thing, domestic physicists have finally gotten together, and many people have proposed to hold a symposium tomorrow, where everyone will sit together and talk about the future and direction of physics." Xu Zhengping said and looked at Su Zhe and Fan Xiaoming.

"Tomorrow!" Su Zhe hesitated.

"What? Do you have anything to do tomorrow? Xu Zhengping asked with a smile.

"We are going to Northwest University of Electronic Science and Technology tomorrow to participate in the completion ceremony of the Chasing Light Engineering Experimental Station." Fan Xiaoming explained.

"That's it! I thought something was wrong! Xu Zhengping smiled and said, "Let's say so!" Many of the physicists sitting in Lecture Hall 1 have been invited, and so have I, as well as the launch of the Xuanwu Program space probe on the 22nd. ”

"And how did the headmaster arrange it?" Fan Xiaoming asked with a smile.

"I think so, Northwest University of Electronic Science and Technology is more than 200 kilometers away from our school, and then to the satellite launch center is also 100 kilometers, the school will arrange buses, first to participate in the 21st Northwest University of Electronic Science and Technology Chasing Light Engineering Experimental Station completion ceremony, and then to participate in the 22nd Xuanwu Program space probe launch, and finally our school went directly to the Tamu Gobi." Xu Zhengping said with a smile.

"That's good! That's good! ”

Su Zhe and Fan Xiaoming smiled and nodded.

After saying a few more words, Xu Zhengping returned to the No. 1 lecture hall, and Su Zhe and Fan Xiaoming left the top floor of the West Building and came to the spiral staircase.

"It's really good, let's take it as a tourist, anyway, the three places are not far away." Fan Xiaoming said as he went down the stairs.

"Yes!" Su Zhe smiled and nodded.

……

The next day, the Great Hall.

When Su Zhe and Fan Xiaoming came to the auditorium, it was crowded!

The large auditorium, which was not too big, was packed with people.

Except for those physics elders, the other main ones are teachers and students of the Faculty of Physics.

After receiving the news, these teachers and students came to the auditorium early to take their seats.

The symposium was presided over by Academician Wang Xiuqi, Dean of the School of Physics.

In the beginning, everyone talked about the cultivation of physics talents.

Speaking of this, the elders highly praised the Four Books Society, saying that the Four Books Society not only streamlined the physics textbooks, but also sorted out and summarized the knowledge related to physics.

In this way, it is greatly convenient for teachers and students to learn.

For such praise, the students of the first physics class at the scene were very useful.

Then he talked about the academic journal of physics.

At this time, some elders said that the students of the School of Physics of Lingzhou University of Technology stubbornly lifted the "Journal of Science" run by the Academy of Sciences.

President Xu Zhengping explained with a smile that this is not just the School of Physics, but the entire Lingzhou University of Technology first-year students.

He also said that the first-year students of this class were more confident than the students of the past, and the first-year students at the scene were very happy.

When talking about this topic, the physics elders of the Academy of Sciences were very happy.

In the past, few people at home and abroad submitted high-quality papers to the Journal of Science of the Academy of Sciences, and in the eyes of those people, English was good, and foreign papers were good.

The first-year students of Lingzhou University of Technology did not do this, and the papers were written in Chinese, and the most important thing was that these papers were of high quality.

Slowly, the wind began to change, and more and more people submitted articles to the Journal of Science.

The crowd talked and talked about big scientific devices.

From synchrotron radiation installations being built everywhere in the country, there is talk of the Hadron Collider.

At this time, many people are lamenting that the Large Hadron Collider project led by the School of Physics of Lingzhou University of Technology has been delayed.

At the same time, everyone rejoiced in the Super Hadron Collider complex project led by the Nine Days Research Center.

In less than half a year, the Nine Days Research Center is already asking for money, money, and people.

In the past, the whole country wanted to build the Large Hadron Collider, but due to the problem of scientific research funding, the project failed again and again.

But now, the Nine Days Research Center alone is about to build a more advanced Super Hadron Collider complex.

When talking about the Large Hadron Collider, Fan Xiaoming began to introduce the Super Hadron Collider complex.

From the design of the Super Hadron Collider complex, to the performance of the Super Hadron Collider complex.

As he spoke, the eyes of the physicists in the auditorium were red.

According to Fan, the Super Hadron Collider complex will be the most powerful collider in the world.

It is no exaggeration to say that the Super Hadron Collider complex, once built, will be able to do all the experiments on high-energy particles known today.

Fan Xiaoming finally talked about building a more powerful hadron collider in space.

Hearing this, the physics elders became even more excited.

……

In the afternoon, everyone began to talk about the direction of physics.

Nothing more than studying the bigger and smaller.

Reach the structure of the universe, down to elementary particles.

At half past four in the afternoon, the symposium ended.

After dinner, the physics elders packed up and took a bus to Northwest University of Electronic Science and Technology, which is 200 kilometers away.

The whole journey was at high speed, and when Su Zhe and a group of physics elders arrived at Northwest University of Electronic Science and Technology, it was half past eight in the evening.
