I Don’t Want to Win Lying Down

How to solve?

In order to let the five graduate students know the rapid growth mechanism of the supermassive black hole more intuitively, Xu Mang deliberately used the 3D software on the computer to create a dynamic diagram, and used this dynamic diagram to explain the relevant explanations.

This is a supermassive black hole discovered by the Chandra Roentgen Ray Observatory. Xu Mang handed a piece of information in front of several people, and said with a serious face: It exists in the core of most galaxies, located at about 130 One billion light years away.

This means that this supermassive black hole must have formed rapidly after the death of the first batch of stars. Xu Mang paused, and continued: However, it has not been found that there is enough dust and gas in the early universe to explain this rapid growth. growth of.

Immediately afterwards,

Xu Mang took out another piece of information, handed it in front of the five people, and said, This is the early quasar report, and there are twelve quasars with astonishingly dense hydrogen clouds. luminescence to identify.

Well?

Hydrogen cloud?

What's the meaning?

The five graduate students looked at Xu Mang in bewilderment, feeling a little confused about why they took out the hydrogen cloud.

Don't worry.

I haven't spoken yet. Xu Mang said indifferently: These clouds 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 for about About one hundred thousand light-years.

From this, we can draw a conclusion that these gas halos are closely connected with galaxies, providing a perfect source of food for the rapid formation of stars and the growth of supermassive black holes. Xu Mang said: That is to say, in the original galaxies There is enough food to sustain the growth and vigorous star formation of supermassive black holes.

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 looked up at the graduate students from the Department of Physics of Furen University and smiled. He asked, Any more questions?

...

...

...

for a while,

The hearts of the five people received 10,000 points of critical damage,

Why is it that a difficult problem that confuses everyone can't survive half an hour in Professor Xu's place? He just looked through the data he submitted, and then found proof materials from these materials.

Why didn't I discover it in the first place?

this...

Is this the difference in strength?

Continue to study... Adjust your thinking and think about ancient gas clouds. Xu Mang said indifferently: Give me a complete research report in fifteen days, you can go back now, yes... If you want Borrow some astronomical equipment, give me a report, and I will contact you, and anyone in China can contact you.

moment,

Watching the five graduate students leave, Xu Mang couldn't help but sighed. He hurriedly picked up the phone next to him and called Director Fang Jun of Fuda Physics Department.

Hello?

Guess who I am? Xu Mang asked with a smile, There is no reward for guessing correctly.

...

Xu Mang? Fang Jun said helplessly, What is the purpose of calling me? By the way, you are also the person in charge of the Xu Yang Research Institute. Don't start with 'Guess who I am', that's too bad. Steady.

Ahem!

Don't forget the original intention. Xu Mang said awkwardly but politely: Director Fang... By the way, the score line of Fuda Physics Department was very low? The ten graduate students you asked to come here don't seem to be doing very well. , I feel a little ignorant.

...

You can't use your own template to consider the other party, you... You guy hasn't taken much class, but you jumped to the professor in a year, and you got a deputy director away. Not everyone's experience is the same. It’s the same as you.” Fang Jun smiled wryly and said, “Cultivate me well, I still have something to do... hang up first.”

Snapped!

Just hang up the phone.

Xu Mang almost died of anger. When did someone hang up on him?

wrong...

Xiaoman often hangs up the phone.

...

Time passed by every minute, every second,

Another two days passed.

Xu Mang basically completed the problem of scattering uncharged neutrons, and a neutron diagnostic device with completely independent property rights was born, but... Xu Mang did not report this device, and he always felt that he could not solve the real problem. Charged neutrons don't get trapped, which annoys them.

sorry,

The pride in my heart cannot accept such a situation.

Of course, excessive pride will eventually end in failure. Xu Mang knew this truth, and while working hard to break through the problem that uncharged neutrons would not be restrained, he stepped up to carry out relevant simulation tests on the neutron diagnostic device.

For this reason, Xu Mang developed a diagnostic system. After the neutrons in the field of view of the neutron diagnostic device are scattered, the proportion of scattered neutrons can be checked, so that we can clearly know how many uncharged neutrons there are at this time, and these data It will be displayed in front of the scientific community in a very intuitive way.

hiss...

It doesn't feel like enough. Xu Mang frowned, and modified the system temporarily, adding measurement data such as emission spectrum, yield, space, time distribution, radiation dose, etc., to diagnose the neutrons caused by uncharged Combined impact.

at this time,

The neutron diagnostic device is truly complete.

Hello?

Wife? Xu Mang received a call from Xiaoman, and asked curiously, Are you going to the capital for a meeting? What kind of meeting are you having?

well...

The high-tech industry technology conference is all bigwigs in the high-tech industry. Yang Xiaoman pouted, with a hint of displeasure in his tone: I don't fit in with them, I don't want to go at all, 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 calmly, Isn't it our daily life to fly around?

you do not know!

They are very dissatisfied with my monopoly of photoresist materials, and then... I monopolized flexible materials. Yang Xiaoman said angrily: They are even more dissatisfied, husband... What if they gang up to bully me ? After all, I am fighting alone.

Suddenly, Xu Mang fell into silence, just for a while, and said with a smile, Don't panic, you still have me!

Um!

By the way... Yang Xiaoman suddenly remembered something, and asked seriously: Christmas Eve, Christmas, Valentine's Day, you didn't accompany me... What should you do?

Hello?

Hello?

What's the situation? Here... why is there no signal? Xu Mang looked at his full signal, opened his eyes and began to talk nonsense: These communication companies...the service quality is so poor.

Snapped!

hung up

He took a long breath, Xu Mang felt like he was going to survive a catastrophe, so dangerous... almost fell into Xiaoman's trap, but he had to face her request when he returned home, what the hell 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 can of tea in front of Xu Mang, and said with a smile, This is a bribe.

ah?

What do you want to do by sending me a can of tea suddenly? Xu Mang asked curiously.

I have another nephew who graduated from the University of Science and Technology with a master's degree in materials. Brother Chuan Xiao said, I'm worried about finding a job. Work, can you give me a chance?

A master's degree from the Department of Materials? Xu Mang was stunned for a moment, and said with a smile: Come on! I just want to tell you a plan. Isn't there an empty piece of land next to us? My wife has already won it, and the future is on the side Shangjian Materials Research Institute.

Let him come here first?

sure!

It just so happens that antiferromagnetic topological quantum materials need him. Xu Mang said, I think the quantum materials team is finished... There has been no movement for several days, and the five people are probably very desperate.

The difficulty you gave is too high. Brother Chuan Xiao said: The difficulty of going 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?

Um!

This is a neutron diagnostic device. I don't have the ability to solve neutron scattering yet. Xu Mang sighed, showing a hint of helplessness: Maybe it can be solved sometime in the future, but it's definitely not now. I can't find it now. to the point of solution.”

or...

You report this first. Gyre No. 2 is just an experimental platform, and No. 3 and No. 4 will come out in the future. You can solve the neutron scattering in the spare time, but... now you need to alleviate their urgent needs. Brother Chuan Xiao said.

don't even say,

It sounds so reasonable.

finally,

Xu Mang called Academician Zhou.

Hello?

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 No. 2 project urgent? Is time urgent?

Time is tight.

It will be launched in about half a year, but we still have some problems to solve. Academician Zhou said with a wry smile: We will wait for you to simulate the system, and there is also the problem of neutron scattering.

Yes!

The simulation system is still waiting!

It was only then that Xu Mang remembered that he had been given another task, the pre-simulation system of Circulation No. 2. Now that he thought about it, the time was quite tight, but the system for this simulation link should be implemented after returning from the United States.

Academician Zhou...

I have some news for you. Xu Mang said cautiously, I can't solve the physical phenomenon that uncharged neutrons are not restrained 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 problem of neutron scattering, Xu Mang said.

Academician Zhou was stunned for a moment, he had misheard, and hurriedly asked: You...you found a solution to the problem of neutron scattering in thermonuclear fusion?

right!

found it!
