Chapter 752: 1 temporary solution (one/three)

How to solve?
In order to let the five graduate students know the rapid growth mechanism of supermassive black holes more intuitively, Xu Mang deliberately used the three-dimensional software on the computer to make a dynamic graph, and used this dynamic graph to explain the relevant explanation.
"This is a supermassive black hole discovered by the Chandra Roentgen Ray Observatory." Xu Mang handed a piece of information to a few people, and said with a serious face: "It exists in the core of most galaxies, almost located in one hundred and three. 1.1 billion light years away."
"This means that this supermassive black hole must be formed quickly after the death of the first stars." Xu Mang paused and continued: "However, it has not been discovered that there is enough dust and gas in the early universe to explain this rapid growth of."
Immediately after,
Xu Mang took out another piece of information and handed it to the five people, saying:
This is an early report on quasars. Among them, there are twelve hydrogen clouds with amazing density. These hydrogen clouds are unique under ultraviolet light. To recognize it by the light."
Uh?
Hydrogen cloud?
What do you mean?
The five graduate students looked at Xu Mang dumbfoundedly, feeling a little confused as to why they took out the hydrogen cloud.
"Don't worry."
"I haven't spoken yet." Xu Mang said indifferently: "These clouds composed of cold and dense hydrogen are billions of times the mass of the sun, forming a halo around the early galaxies. These galaxies extend from the center by approximately About one hundred thousand light years."
"From this we can draw a conclusion that these gas halos are closely connected to galaxies, providing a perfect source of food for the rapid formation of stars and the growth of supermassive black holes." Xu Mang said: "In other words, they are indeed in primitive galaxies. There is enough food to sustain the growth of supermassive black holes and powerful star formation."
"Of course all of this is my guess. If you want to know more about the formation code of supermassive black holes, you need to study the details of the original gas cloud." Xu Mang raised his head and glanced at the graduate students in the Department of Physics of Wuren Fu University, and laughed. Asked: "Any questions?"
"..."
"..."
"..."
For a while,
The hearts of the five people were injured by a critical strike of 10,000 points. Why did a problem that puzzled everyone, but did not survive for half an hour in Professor Xu? He just flipped through the data he submitted, and then found the proof from the data.
Why didn't I find it in the first place?
This...
This is the gap in strength?
"Continue to study... adjust your thinking and think about ancient gas clouds." Xu Mang said calmly: "Give me a complete research report in fifteen days. Go back now, right... if you want What astronomical equipment can be borrowed, give me a report, and I can contact them, and I can contact them in China."
moment,
Seeing the five graduate students leave, Xu Mang couldn't help sighing. He hurriedly picked up the phone beside him and made a call to Director Fang Jun of the Physics Department of Fuda.
"Hey?"
"Guess who I am?" Xu Mang asked with a grin: "There is no reward for guessing right."
"..."
"Xu Mang?" Fang Jun said helplessly: "What is the purpose of calling me? You are also the person in charge of Xu Yang Research Institute anyway. Don't say "Guess who I am" in the opening remarks. Be steady."
"Cough!"
"Don't forget your original intention." Xu Mang said awkwardly and politely: "Director Fang...what if the score line of the Department of Physics of the Fuda University was very low? The ten graduate students you sent over did not seem to be very good. , I feel a little ignorant."
"..."
"You can't use your own template to consider each other, you...you guys haven't been in class much, and in a year you jumped to the professor, and you got rid of a deputy director. Not everyone's experience is It's the same as you." Fang Jun smiled bitterly: "Train it, I still have things... I'll hang up."
Snapped!
Hang up the phone directly.
Xu Mang almost didn't get angry. When did he hang up by someone else?
wrong...
Xiaoman often hangs up the phone.
...
Time goes by every minute,
Two more days passed.
Xu Mang basically completed the scattering problem of uncharged neutrons, and a neutron diagnostic device with completely independent property rights was born. However... Xu Mang did not report this device, and he was always unable to solve the real problem. The charged neutron will not be restrained, and will feel annoyed.
Sorry,
Inner pride cannot accept such a situation.
Of course, excessive pride ultimately ends in failure. Xu Mang knows this truth. While working hard to break the problem that uncharged neutrons will not be constrained, he stepped up to conduct related simulation tests on the neutron diagnostic device.
For this reason, Xu Mang has developed a diagnostic system. After the neutrons in the field of the neutron diagnostic device are scattered, the proportion of scattered neutrons can be checked. From this, it is clear how many uncharged neutrons are at this time, and these data It will be displayed very intuitively before the eyes of the scientific community.
"hiss..."
"It doesn't feel enough." Xu Mang frowned, and temporarily modified the system, adding measurement data such as emission spectrum, yield, space, time distribution, radiation dose, etc., to diagnose the problem caused by uncharged neutrons. Comprehensive impact.
at this time,
The neutron diagnostic device is truly complete.
"Hey?"
"Wife?" Xu Mang received Xiaoman's call and asked curiously: "Are you going to the capital for a meeting? What meeting are you holding?"
"Ugh..."
"The high-tech industry technology conferences are all big names in the high-tech industry." Yang Xiaoman pursed his mouth, with a hint of displeasure in his tone: "I don't fit them, I don't want to go, but this It’s an official invitation."
"Just go, I'm going to the United States to participate in the forum in five days." Xu Mang said indifferently: "Flying around, isn't it our daily routine?"
"You do not know!"
"They were very dissatisfied with my monopoly of photoresist materials, and then...I monopolized the flexible materials again." Yang Xiaoman said angrily: "They are even more dissatisfied, husband...what if they unite to bully me ?After all, I fought alone."
Suddenly, Xu Mang fell into silence, just for a while, and smiled: "Don't panic, you still have me!"
"Ok!"
"By the way..." Yang Xiaoman suddenly remembered something and asked seriously: "You didn't accompany me on Christmas Eve, Christmas, Valentine's Day... What should you do?"
"Hey?"
"Hey?"
"What's the situation? This... why is there no signal?" Xu Mang looked at his full signal, and opened his eyes to start talking nonsense: "These communication companies...the quality of service is so poor."
Snapped!
Hung up,
With a long sigh, Xu Mang felt like he was left behind. It was so dangerous... he was almost fooled by Xiaoman, but he had to face her requirements when he returned home. What should I do?
Bang bang bang,
There was a knock on the door, and then Brother Chuan Xiao walked in, holding a pot of tea in his hand.
"Xu Mang."
"Drink this tea, you will definitely fall in love with it." Brother Chuan Xiao handed the pot of tea in front of Xu Mang and said with a smile, "This is a bribe."
"what?"
"What do you want to do when you suddenly gave me a can of tea?" Xu Mang asked curiously.
"I have another nephew who graduated with a master's degree in materials from the University of Science and Technology." Brother Chuan Xiao said: "I am worrying about finding a job. He is very oriented. He doesn't want to enter any company, but wants to be in a research institute. Work, can you give me a chance?"
"Master from the Department of Materials?" Xu Mang froze for a moment, and said with a smile: "Come on! I just told you a plan. Isn't there a piece of land next to us? My wife has already won it, and the future is on the side. Shanghai Institute of Materials Research."
"Let him come first?"
"sure!"
"It just happens that anti-ferromagnetic topological quantum materials need him." Xu Mang said: "I think the quantum materials team is over...there has been no movement for several days. I am afraid that all five of them are desperate."
"The difficulty you gave is too high." Brother Chuan Xiao said: "Come up to hell, they are not you."
Words fall,
Seeing the research report on Xu Mang's desk, he asked curiously: "Have you completed the neutron scattering problem?"
"Ok!"
"This is a neutron diagnostic device. I still don't have the ability to solve neutron scattering." Xu Mang sighed, showing a trace of helplessness: "It may be solved at some time in the future, but it is definitely not now. I can't find it now. To the entry point of the solution."
"or..."
"You report this first. Circumfluence 2 is only an experimental platform. There will be 3 and 4 coming out in the future. You can solve the neutron scattering in the gap time, but... now you need to alleviate their urgent needs." Brother Chuan Xiao said.
Not to mention,
It sounds very reasonable.
finally,
Xu Mang dialed Academician Zhou's phone.
"Hey?"
"Academician Zhou...Are you busy?" Xu Mang asked with a smile.
"Xu Mang?"
"It's okay..." Academician Zhou was a little surprised when he received a call from Xu Mang.
"Oh... it's okay." Xu Mang said cautiously: "Academician Zhou...I want to ask, is the Huanliu Project 2 in a hurry? Is time pressed?"
"Time is tight."
"It's almost half a year to start, but we still have some problems that have not been resolved." Academician Zhou smiled bitterly: "We will wait for you to simulate the system, and there is still the problem of neutron scattering."
Yeah!
The simulation system is still waiting!
Xu Mang then remembered another task he was given to ~EbookFREE.me~The early stage simulation system of Circumfluence II. Now it is quite tight to think about it, but this simulation system should come back from the United States. Do it again.
"Academician Zhou..."
"Tell you a piece of news." Xu Mang said cautiously: "I can't solve the physical phenomenon that uncharged neutrons are not constrained for the time being...I need a particle collider to conduct related experiments and find a solution from the data."
"but..."
"In the thermonuclear fusion device, I temporarily found a solution to the neutron scattering problem." Xu Mang said.
Academician Zhou was taken aback for a moment, he had already heard it wrong, and hurriedly asked: "You... have you found a solution to the problem of neutron scattering in thermonuclear fusion?"
"Correct!"
"found it!"
