I Don’t Want to Win Lying Down

As for how to solve the problem of neutrino double-beta decay, Xu Mang casually tossed it out when he was taking care of the children in his spare time. He didn't take it seriously at first, just to pass the time, but who knew... it came suddenly interest.

Actually... because it was so difficult, it aroused Xu Mang's desire for knowledge. After about three weeks of tossing around, he finally solved the neutrino double-beta decay problem. The rest is the experiment, but Xu Mang felt uncomfortable. Need to experiment, according to their own simulation calculations... definitely not a problem.

at this time,

Hearing Xu Mang's words, all the students present were shocked. At first, everyone was not sure... After all, neutrino double beta decay is not a simple problem. Ettore Majorana published a paper hypothesizing this This kind of particle exists, and it has been almost 90 years now, and it has never been solved.

It is conceivable that

How difficult is this.

But now Academician Xu actually said that he solved it by himself. This kind of shock cannot be described in words. I can finally see the miracle of Academician Xu with my own eyes. something.

Fuck...

No way? He Weijie's friend said in horror: Unexpectedly, today is really the right time... I have lived up to the expectations of these few days, and I have the capital to brag when I go back this time. After all, I also witnessed Academician Xu with my own eyes. The one who created the legend!

He Weijie didn't speak, but his emotions were similar to those of his friends. Apart from being shocked, he was more eager for the unknown, but he was still a little unconvinced... Human beings have spent ninety years on this problem, and suddenly one day was resolved.

About this formula...

I'll get to that later, first the Standard Model predicts that the two neutrons in the nucleus will convert into a proton and two electrons, and emit a two-electron antineutrino, which is called a double-neutrino double Beta decay. Xu Mang said indifferently: Double neutrino double beta decay is very rare, this is due to the super long half-life of double beta isotopes above 1020 years.

So...

How to find a suitable isotope? Xu Mang continued: Simulate the decay of tin-100 into the adjacent element indium-100 on the periodic table...these two elements have the same number of protons and neutrons, of which tin- 100 has 50 protons, while indium-100 has 49.

Accurate decay calculations not only need to accurately simulate the structure of the mother nucleus and the daughter nucleus, but also need to consider the interaction of the two nucleons during the transition process. Xu Mang glanced at everyone present and said expressionlessly: At this time...a very precise calculation tool is required.

words fall,

Xu Mang turned around and pointed to the formula on the blackboard, and said seriously, And this is the answer... the structural problem used to establish the decay model.

!!!

!!!

!!!

This is based on such a short formula?

Everyone now looked at the direction of Xu Mang's finger, and for a moment didn't know how to describe it. How much intelligence was needed to create such a pattern. At this moment...many people thought of a person who only appeared in rumors. Formula——Xu Yang's structural formula.

This formula is almost blown up in various magazines, saying that it is a masterpiece that condenses the most outstanding wisdom of human beings, but almost no one sees this legendary formula, but they know that this formula must exist, because relying on the Solved countless problems.

Could it be...

Is this formula on the blackboard the same as the legendary Xu Yang structural formula?

Just when everyone was confused, Xu Mang said with a smile: This is just a small tool... It's not a formula that can solve anything, so... As I said before, this is a formula , it’s just the key to solve special problems, not the same structural formula as Xu Yang’s that you think.”

So it is!

But this is also very, very awesome!

All the students out there,

His eyes widened, anticipating the next new content.

as expected,

Xu Mang formally explained how this formula came about.

At a 90 percent confidence level, the half-life is about greater than 1.1×1025 years... an increase from the previously measured 1.6×1025 years. Xu Mang said: This long lifespan indicates The mass of the sub may be less, then...

at this time,

At the back of the classroom, a group of professors listened with gusto. Although some professors were not experts in this field, they were all interoperable. These professors also hoped to learn something from Xu Mang's experience. learn old.

Strong!

It's too strong... A very reasonable conclusion can be drawn from pure calculations and simulation experiments. Fan Zhilong said with a wry smile: But thinking about it, this is also a normal behavior... He used to do this, a People sat in the office, relying on computers and pens...the problem was solved in a few days and nights.

well...

The gap between us and Xu Mang is getting bigger and bigger. He seems to be around twenty-five? Professor Li Aimin said with emotion, Oh... I remember when Xu Mang first entered school, he seemed to be a liberal arts student. I came in as a student, and I was worried that he would not be able to keep up, so let him try for half a year or two months.

Yeah!

At that time, after two weeks of class, there was basically no one there. Zhong Yuan said: Afterwards, he became a lecturer, then an associate professor, and finally became the deputy director of the physics department. At that time, the list was reported. At that time, others were almost not scared to death, but fortunately Xu Mang had already won many achievements at that time, and led a scientific research team independently.

Speaking of the past,

My mind was full of memories, but everyone was a little sad as they talked. In fact, Xu Mang did not end perfectly in Fuda. He left with flaws. At that time, Xu Mang was standing in the circle of storm. anger left.

At that time, there was no one to help him, so he had to rely on himself to solve it, or it was the pressure... that caused him to leave, and then the principal who had been taking care of him left. was revoked.

hope...

In the future, Xu Mang will have a perfect ending at Fuda! Fang Jun said seriously.

...

on the Internet,

The small video about Xu Mang in the public class has already appeared in the public's view, such as a video app like Shaking Hands, not to mention...the number of hits is very high, but most of them are just shouting awesome In other words, there were some bullies trying to overthrow Xu Mang's content.

And this kind of bullshit has an obvious characteristic, that is, they like to explain everything with their own thoughts, and they don't have any scientific literacy. In an instant, these bullshit remarks were overturned by other netizens, and they left silently.

Fuck... Academician Xu is so fucking awesome!

66666!

Academician Xu, I want to give birth to a monkey for you!

The Internet has exploded, and at the moment in the open class, the students have gradually entered a stage of confusion. At first, everyone listened with gusto, thinking that Academician Xu's actions were simply amazing, and then... something strange happened. The change.

When Xu Mang explained how to use the idea of ​​treating electrons as waves in quantum chemistry to develop a simulation experiment technology, almost everyone had a big question mark in their heads.

So now...we are dealing with so-called nucleons instead of electrons. In the concept of quantum chemistry...we can branch out the double beta decay nuclei and expand them to these open-shell regions. Xu Mang continued Said: Proving that the theoretical understanding of beta decay agrees with the simulated experimental data, next...

He continued, and seemed to get more and more excited as he talked, which made the students miserable.

Fuck!

who I am?

Where am I?

what should I do?

I can't understand this shit at all! How on earth does this tell from double beta decay to quantum chemistry? And this so-called nuclear branch...how is it extended into the open-shell region? How does this theoretical theory correspond to the simulated experimental data?

Everything is unknown to the students present.

I rely on...

Hey... Weijie? He Weijie's friend cautiously asked the friend next to him: This...have you heard what Academician Xu is talking about? Why do I feel like I'm listening to heavenly scriptures? He... What the hell is he talking about?

I...

I... He Weijie was also full of confusion at the moment. Even though he was hailed as the genius closest to Xu Mang, he was so small in front of the real genius. I don't know what to say, and now my eyes are smeared, and I don't know anything.

this moment,

Xu Mang, the most powerful genius in Fuda's physics department, completely broke his confidence.

at the same time,

Fang Jun gradually felt something strange. He found that many students had completely entered the dementia mode in the face of Xu Mang's explanation. understand something.

Go on like this...

This batch of the most promising future stars will be ruined by Xu Mang!

It's over, it's over...

Xu Mang has entered the state! Fang Jun said nervously: He subconsciously regards these students as being on the same level as him, and if this continues...the confidence of these students will be destroyed by him. destroyed.

But,

There's still more than an hour left until the end,

It would not make sense to stop Xu Mang's lecture at this time... and no one at the scene dared to stop him, not to mention that Xu Mang's identity had completely crushed all the professors, so he was invited by Principal Zheng No one has the power to stop the guest professor.

Now I make a bold prediction!

Calculations using different neutronless double-beta decay nuclear models may have a difference of up to six times! Xu Mang pointed to the original formula, then pointed to a piece of content that reappeared on the blackboard, and said, First This place... is an unknown variable, and to solve this unknown variable, a new benchmark needs to be provided...

the next hour,

For these students, it was completely crazy... For the first time, they felt that the class was so full of torture. They clearly had the most cutting-edge scientific discoveries in front of them, but due to the limitations of their own strength, they couldn't touch them at all.

finally,

Xu Mang finished speaking... These three hours have exhausted him terribly. Due to his dedication, he didn't even take a sip of water. Then he discovered a big problem.

Well?

I rely on!

What expressions do these people have?
