I Don’t Want to Win Lying Down

is it here?

It should be here...

Hope it's here!

Xu Mang stood in front of an office. He wanted to see a scanning tunneling microscope, and Oxford University happened to have a scanning tunneling microscope, and the key was in the hands of Professor Martelli.

bang bang bang,

After a please come in,

Xu Mang hurriedly opened the door and entered, and saw a middle-aged woman standing in front of a blackboard with various calculations written on it.

Huh?

Professor Xu?

When Matley saw that it was Xu Mang, she couldn't help being stunned for a moment, then put on a smile, and asked, Is Professor Xu looking for something for me?

hey-hey...

Hello, Professor Martelli. Xu Mang said with a smile, I'm looking for you mainly to learn about scanning tunneling microscopes.

Scanning tunneling microscope?

Is this related to the gaseous carbon ring you are studying? Professor Martelli asked curiously.

There is no necessary contact, just pure curiosity, and I want to know more about it. Xu Mang said with a smile, I don't know if Professor Martelli would like it. I think this request should be very simple, not very difficult...

Martelli nodded, and said seriously: Professor Xu rarely speaks, so I will help you do it no matter what.

moment,

Matley took Xu Mang to the laboratory.

At first I thought I needed to walk for a while, but in the end I opened the door and walked into the opposite door.

Xu Mang probably knew about the scanning tunneling microscope before. A probe slowly passes through the material to be analyzed, charges are placed on the probe, and a current flows from the probe, through the entire material, to the underlying surface.

As the probe passes through individual atoms, the amount of current flowing through the probe varies, and these changes are recorded.

The principle is that when the current flows through an atom, it rises and falls, so that its outline can be detected in great detail. By drawing the fluctuation of the current, human beings can obtain the grid structure diagram of a single atom.

I understand the truth,

But understanding and operating are two different things. It seems that Xiaoman knows that he is an airport and wants to become bigger. Man has a lot of techniques for getting bigger, but it's a big deal when it's operable.

theory and practice,

no the same!

STM has two working modes, constant current mode and constant height mode. In general, the constant current mode is used. This working mode obtains comprehensive image information and high quality microscopic images.

Of course...the constant-height mode also has characteristics, and the microscopic image is obtained through the tunnel current without the need for a light source and a lens.

pause for a moment,

Martelli went on to say: STM has several functions, and I won't talk about scanning. In addition to scanning, STM can be used to find defects and damage on various structures on the surface, and use methods such as surface deposition and etching. Make or cut the connection to eliminate the defect and achieve the purpose of repair, that is, flaw detection and repair.”

Xu Mang nodded again and again. At this time, he had already activated the memory mode, memorized all the content that Martelli said in his mind, and copied the basic parameters on the manual by the way.

Professor Martelli?

Where did you buy this device? Xu Mang asked, It seems...it looks like it was made by myself.

right!

We provide the drawings, and then the School of Engineering helps us make them. Martelli said with a smile: This STM is almost one of the highest resolutions in the world. experiment.

...

sharp!

Xu Mang was immediately envious, looking at this unattractive iron bump, he instantly started thinking about it.

copy!

Make a complete copy of the most powerful microscopy tool in the world, and then bring it back to make it yourself, so as to avoid being blocked by others in this regard.

well?

Is this part shock-absorbing? Xu Mang asked.

right!

Because the working distance is less than one nanometer, and the tunnel current is exponentially related to the tunnel gap, any vibration will cause instability. It is necessary to isolate the vibration and impact, and the vibration must be isolated! Martelli said: How to reduce the vibration? , I can’t tell, it’s a secret.”

Xu Mang showed a slight smile, and nodded at Ma Terry: I can understand.

actually,

At this time, Xu Mang probably guessed how to absorb the vibration, which cannot be achieved by relying on the spring itself. It is estimated that the frequency of the external vibration and the natural frequency of the instrument were cut in, and the frequencies of the two were coordinated to a value.

after all,

It's easy to do with a computer.

Immediately afterwards,

Xu Mang asked a lot of questions, but Professor Martelli only talked about the general content, with some reservations about Xu Mang. Know.

This function parameter setting... Martelli is completely confidential.

For this,

Xu Mang had no choice but to accept it. Although there must be a scanning tunneling microscope in China, the resolution is not as high. As a result, compared with foreign countries, he is at a disadvantage in studying atoms.

Back in Martelli's office, Xu Mang chatted with her for a while, then noticed the calculation process on the blackboard.

Professor Martelli is studying... the single resonance model to study the dispersion characteristics of the medium? Xu Mang asked with a smile.

After hearing Xu Mang's words, Matelli's expression changed slightly, she nodded and said, That's indeed the question. I didn't expect Professor Xu to know a lot about electromagnetism and electrodynamics!

Okay...

It seems that the calculation process is stuck, right? Xu Mang said, It's normal to be stuck here.

...

Martelli didn't speak, and she suddenly realized that the person sitting in front of her was not an ordinary person, but a man who used mathematics to the extreme.

perhaps,

The problem I encountered was not a problem at all in the eyes of Professor Xu.

After all, it is not possible for everyone to discover the essence of the problem at a glance.

Professor Xu...

Can you help me with this? Professor Martelli's attitude became somewhat respectful.

all right!

This question is not difficult, at least it is not difficult for me. Xu Mang said with a smile: But... I really want to know the parameter settings of STM. Of course, I just take a look to get a general idea.

Matley pondered for a long time, and generally refused, but the person sitting across from her was not an ordinary person, and she couldn't be treated with ordinary circumstances.

good!

words fall,

Matley took out a notepad, handed it to Xu Mang, and said seriously, This is the specific parameter setting.

Xu Mang smiled and said thank you.

The system...turn on the memory mode!

[Memory mode start]

The system...turn on the animal mode!

[Beast mode starts]

after,

Xu Mang frantically flipped through the parameter settings above, not to mention...it was really detailed.

After seeing Xu Mang's speed, Matley was completely relieved. It was really just flipping around casually. If this speed could be remembered, then this world would be too dangerous.

less than ten minutes,

Xu Mang handed the notebook back to Martelli, and said gratefully, Thank you...

No no no!

Professor Xu is polite. Martelli said with a smile.

hehe...

Then as a return...I will solve the problem you encountered, and I will also attach it to you later. Xu Mang said seriously, Do you have any paper and pen?

Give!

moment,

In front of Matelli, Xu Mang began to solve the problems she encountered.

high speed,

It was almost to the point where Professor Martelli was terrified.

this...

How can this be so fast?

real or fake?

this moment,

Professor Martelli began to doubt her life. It was the first time she encountered such a situation, and the speed was so fast that it was impossible to look directly at it. Can there be a correct rate at such a speed?

Are you lying to me?

Swish Swish Swish,

still going on...

Xu Mang quickly solved the problem that Professor Martelli encountered in the calculation. In fact, this problem is not very difficult. The difficulty lies in the splitting of a long formula, which needs to be split into four sections skillfully. Otherwise, it will not be untied in this life.

untie...

solved?

Only a few minutes have passed!

Matley saw that one of her problems seemed to have been solved, but Xu Mang didn't stop writing because of this.

soon,

After another ten minutes, Xu Mang silently put down the pen in his hand, picked up a dozen sheets of white paper, and said with a smile, It's no good... I'm getting old. I used to be able to do it for an hour, but now it's less than an hour. Twenty minutes, I'm really tired.

good!

It's all resolved. Xu Mang handed the blank paper full of progress to Professor Martelli, and said, I'm leaving...

words fall,

Xu Mang left the office directly, leaving behind a bewildered Matelli.

I...

This is too... too neat, right?

Xu Mang's operations completely confused Professor Martelli. She began to doubt the world and whether aliens existed. She had thought about this question for a day, but others solved it in a few minutes. Solve it together.

say,

Is it right?

That's what Mattie cares about.

Subsequently,

Professor Martelli sat in the office and began to read Xu Mang's process. He felt a little fear when he watched it. So...the solution to the problem he encountered was so simple? !

but...

Martelli knows that behind the seemingly simple, there is actually a lot of painstaking efforts, and only people like Professor Xu can feel simple.

five minutes later,

Martelli intends to share this process with her two colleagues, and experience the top strength in the industry together.

...

Matley?

Aren't you solving the problem of the characteristics of the dispersion of the medium? Dean asked curiously when he saw Martelli coming, Why did you come to me all of a sudden?

I...

Professor Martley glanced at Dean and Bill, and said seriously: My problem has been solved...

???

???

untie...

solved?

Dean and Bill knew what kind of problem Martley encountered, it was a mathematical calculation problem, and Martley's math ability was not outstanding, unless she found a professor in the mathematics department, but... .She doesn't seem to get along with the math department.

Immediately afterwards,

Martelli took out a dozen blank sheets of paper, handed them to Dean, and said, Bill, come and take a look!

just a few minutes,

Dean and Bill looked at Martley in horror.

Matley?

You...you made a compromise with the math department?

at this time,

Professor Martelli showed a slight smile, and said firmly: No...the above calculation process comes from a professor of theoretical physics!
