I Don't Want to Win Lying Down

Chapter 1153

As for how to solve the problem of neutrino double beta decay, Xu mang casually tossed it out when he was taking care of his children in his spare time. Originally, he didn't do it back, just to pass the time, but who knows... He suddenly came to be interested.

In fact, it was so difficult that Xu Mang's desire for knowledge was aroused. After nearly three weeks' hard work, he finally solved the neutrino double beta decay problem. The rest was the experiment, but Xu didn't think it was necessary to experiment. According to his own simulation calculation, there would be no problem.

At this time,

hearing Xu Mang's words, all the students present were shocked. At first, we were not sure... After all, the double beta decay of neutrinos is not a simple problem. According to the paper published by etore mayorana, it has been nearly 90 years since the existence of such particles has never been solved.

It is conceivable that the difficulty of

is very high.

But now academician Xu even said that he had solved the problem. This shock can not be described by words. Finally, he can see the miracle of academician Xu with his own eyes. In the past, he only looked at his deeds and pictures in online posts, and always felt that there was something missing.

"Horizontal trough..."

"won't it?" He Weijie's good friend said in horror: "I can't believe that today is really right... I didn't live up to the expectations of these days. I have the capital to boast when I go back this time. After all, I have witnessed academician Xu's creation of legend with my own eyes."

He Weijie didn't say anything, but his mood was similar to his friends. He was more anxious for the unknown than shocked, but he was still a little unconvinced in his heart. Human beings spent 90 years on this problem, and all of a sudden, it was solved one day.

"About this formula..."

"I'll talk about it later. First of all, according to the standard model, two neutrons in the nucleus will be converted into one proton and two electrons, and emit two electron anti neutrinos, which is called Double neutrino double beta decay." "The double neutrino double beta decay is very rare, because of the long half-life of the double beta isotope over 1020 years," Xu said indifferently

"So..."

"how to find the right isotope?" "Simulating the decay of tin-100 into the neighboring 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 and indium-100 has 49 protons."

"Accurate calculation of decay requires not only accurate simulation of the structure of the parent and daughter nuclei, but also the interaction between the two nuclei in the transition process." Xu mang looked at all the people present and said without expression: "at this time... We need a very accurate calculation tool."

Then he turned to the formula on the blackboard and said earnestly, "and that's the answer... The structural problem for building decay models."

“！！！”

“！！！”

“！！！”

With this short formula?

Now everyone looks at the direction of Xu Mang's fingers, and they don't know how to describe it. This is how much intelligence is needed to create such a formula. At the moment, many people think of a formula that only appears in the hearsay - Xu Yang structural formula.

In various magazines, this formula has been almost blown to the sky. They all say that it is a masterpiece that condenses the most outstanding wisdom of human beings. However, we can hardly see this formula at the level of legend. We can know that this formula must exist because we have solved countless problems by relying on the formula.

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

When everyone was confused, Xu mang said with a smile: "it's just a small tool... It's not a formula that can solve any problem, so... As I said before, this is a formula, the key to solve special problems, not that you think it is the same as Xu Yang's structural formula."

So it is!

But this is also very, very exciting!

All the students in the field, eyes wide, looking forward to the next new content.

Sure enough,

Xu mang formally explained how this formula came into being.

"At a 90 percent confidence level, the half-life is about 1.1 × 1025 years... Higher than the previous 1.6 × 1025 years." "This long lifetime indicates that the mass of neutrinos may be small, so..."

at this time,

at the back of the classroom, a group of professors listened with interest. Although several professors are not experts in this field, they are all communicating. These professors also hope to learn something from Xu's experience, after all, they are never too old to learn.

"Strong!"

"It's so strong... It's all possible to draw a very reasonable conclusion by pure calculation and simulation experiments." Fan Zhilong said with a wry smile: "but think about this is also a normal performance... He used to do this before, sitting alone in the office, relying on the computer and pen... Several days and nights to solve the problem.""Alas..."

"the gap between us and Xu mang is getting bigger and bigger. It seems that he is only about 25?" Professor Li Aimin said with emotion: "Alas... I remember when Xu mang first entered the school, he seemed to come in as a liberal arts student. At that time, he was worried that he could not keep up with him, and let him try for half a year or two months."

"Yes, yes, yes!"

"At that time, after two weeks of classes, there was no one left behind." Zhong Yuan said: "later he became a lecturer, then an associate professor, and finally an associate director of the physics department. When the list was published, others were almost not scared to death. Fortunately, at that time, Xu mang had won a lot of achievements and led the scientific research team independently."

Speaking of the past,

his mind is full of memories, but everyone is a little sad. In fact, Xu mang didn't end up in a perfect way. He left with flaws. At that time, Xu mang stood in the storm circle and left with infinite anger.

At that time, no one could help him, so he could only solve it by himself, or the pressure caused him to leave, and then the principal who had been taking care of him left. From then on, he cut off the relationship with Fuda, and even the student aid fund was withdrawn.

"Hope..."

"in the future, Xu mang will have a perfect ending in Fuda!" Fang Jun said earnestly.

...

on the Internet,

on the Internet,

about Xu Mang's small videos in open classes have appeared in the public's view, such as a video app such as shaking a hand, not to mention... The number of hits is very high, but most of them are just shouting Niubi, and some gangsters are trying to overthrow Xu Mang's content.

But this kind of gang Jing has an obvious characteristic, that is, they like to explain everything with their own ideas, and they have no scientific literacy. In an instant, these comments of the gang Jing were overturned by other netizens and left in silence.

"Crouch... Academician Xu is so special, it's so amazing!"

“66666！”

"Academician Xu, I will give you a monkey!"

The Internet has exploded, and now in the open class, students have gradually entered a stage of confusion. At the beginning, everyone listened with interest and thought that academician Xu's doing this was simply amazing, and then... Strange changes took place.

When Xu mang explained how to draw lessons from the idea of regarding 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're dealing with so-called nucleons, not electrons, and in the concept of Quantum Chemistry... We can branch out the nuclei with double beta decay and extend them to these open shell regions." Xu continued: "it proves that the theoretical understanding of beta decay is consistent with the simulated experimental data, and then..."

he continues, and seems to be more excited when he talks, which makes the students miserable.

Sleeping trough!

Who am I?

Where am I?

What should I do?

I can't understand it at all! How does this change from double beta decay to quantum chemistry? And how does this so-called nuclear Branch... Extend to the open shell region? How does the theory correspond to the simulated experimental data?

All this is unknown to the students present.

"I rely on..."

"Alas... Wei Jie?" He Weijie's friend asked his friend carefully, "did you hear what academician Xu was talking about? How do I feel like I'm listening to the book of heaven? What the hell is he talking about? "

"I..."

"I..." he Weijie is also full of confusion at the moment. Even though he is regarded as the closest genius to Xu Mang, he is so small in front of the real genius. Before that, he can still understand the content before, and he will not know anything in the middle. Now, he has a black eye and doesn't know anything.

At this moment,

the most powerful genius in the Physics Department of Fuda was completely defeated by Xu mang.

At the same time,

at the same time, Fang Jun gradually felt a little strange. He found that many students had completely entered the dementia mode in the face of Xu Mang's explanation. They could only sit there foolishly and listen to what he said that he did not understand at all.

If we go on like this...

these most promising stars of the future will be destroyed by Xu mang!

"It's over..."

"Xu mang is in a state!" Fang Jun said nervously: "he subconsciously took these students as a horizontal line with him, and if it goes on like this... The confidence of these students will be destroyed by him."

However,

there is still more than an hour to stop Xu Mang's lecture.

if we stop Xu Mang's lecture at this time, the truth doesn't make sense. Moreover, no one dares to stop Xu Mang's lecture. Let alone that Xu Mang's identity has completely crushed all the professors, no one has the right to stop it."Now I dare to predict!"

"Using different neutron free double beta decay models may differ by up to six times!" Xu pointed to the original formula, and then pointed to a new piece of content on the blackboard, and said: "first of all, this place... Is an unknown variable. If you want to solve this unknown variable, you need to provide a new benchmark..."

the next hour,

for these students, they were completely crazy... They felt that the class was even better However, it is so full of torture that the most cutting-edge scientific discoveries are clearly in front of us. However, due to the limitations of our own strength, we can't touch them at all.

Finally,

finally,

Xu mang finished... These three hours can make him tired. Because of his whole-heartedness, he didn't even drink a mouthful of water. He quickly picked up the pure water on the edge and poured it, and then he found a big problem.

Eh?

Damn it!

What expressions do these people have?
