What's going on?

Why do everyone look so horrified?

Xu Mang was a little confused. This neutron is just one of the nucleons in the atomic nucleus. It is usually composed of two down quarks and one up quark. It is not a scarce thing. Is there any need to make such a fuss?

"Xu Mang?!"

"Are you willing to be the person in charge of this project?" Fang Jun looked at Xu Mang seriously and said seriously: "I'll give you one last chance. Think carefully before answering!"

Xu Mang was stunned for a moment. He vaguely felt a little chill. Could it be that this was a trap?

"I"

"I don't want to?" Xu Mang asked tentatively, and only the other party could hear the words.

"That's good!"

"You will be responsible for this project!" Fang Jun said with a smile.

Xu Mang:???

this

This seems to be a routine!

At this moment, Xu Mang realized that he had fallen into someone else's trap. No wonder he called him over. It turned out that he was just waiting for him to jump. The eight-second difference between neutrons sounded a bit incredible.

tragedy

This is a human tragedy!

Everyone present looked at Xu Mang with sympathy. This project is a bottomless pit that can destroy anyone's inner world.

"Funding issues."

"A total of about 300 million has been allocated from above." Fang Jun said: "This money is not used for special research. If your research is successful, you can continue to use the remaining money and do not need to hand it over."

What?

Isn’t this blood profit?!

Xu Mang has been troubled by funding problems in the past. Most of the funds allocated from above can only be used for special transfers. If you misuse the money, you may suffer serious consequences. However, this time it is not the previous rule. It seems that you have gradually paid attention to the use of funds.

Problem.

Although this is a good thing, everyone present does not envy Xu Mang. The reason is simple and cannot be completed.

soon,

This meeting is over,

Xu Mang was about to get up and go back to the apartment to share the matter with Xiaoman, but he was surrounded by countless people without even a gap.

"Xu Mang, don't you know how difficult this project is?"

"Xu Mang, give up. This is an impossible project. Director Fang is trying to trick you."

"You promised too soon!"

Everyone was trying to persuade Xu Mang to give up the project as soon as possible. There was no need to waste time on a task that could not be completed. This eight-second difference in neutrons had troubled the entire field of physics for fifteen years.

After all, as long as this problem is solved, it will be very important to understand the amount of hydrogen, helium and other light elements formed within minutes after the Big Bang 13.8 billion years ago.

Many physicists believe that if they can further determine the neutron's lifetime, they can open a new chapter in physics, because determining the neutron's lifetime will help constrain the measurement of other subatomic particles.

pity,

impossible

Faced with a flood of persuasion, Xu Mang gradually realized that things were not as easy as he believed. If what his colleagues said were true, he was really being cheated, and the cheating was not as big as usual.

In an instant,

Xu Mang rushed out of the crowd and ran directly to Director Fang's office.

""

""

The two looked at each other, neither of them spoke, and the small office was silent. Just now, Xu Mang proposed to Fang Jun that he would no longer be the person in charge of this neutron project. The previous meetings were all nonsense.

"Xu Mang, let me tell you the truth." Fang Jun said with a bitter smile: "This project itself was prepared for you. In fact, this project was proposed two years ago, but of course no one was willing to study it until you showed up.

Only then did I see a little hope.”

"I?"

"I don't know much about neutrons." Xu Mang asked with a confused face.

"There's no problem if you don't understand it now, and you'll have time to understand it in the future." Fang Jun said: "In short, you are responsible for this project. You can do whatever you like. Of course, it can't be too much. You should be able to understand the appropriateness."

Xu Mang:(°ー°〃)

I see,

Love requires a person to fill the scene!

At this time, Xu Mang knew the truth of the matter. In fact, the so-called large-scale scientific research project was a fireworks show, and he was the one who made the fireworks. Although he knew that no one would come to see it, he still had to do what he should do.

Whether it looks good or not is another matter. At least the fireworks must go up smoothly.

"this"

"Isn't this free funding?" Xu Mang asked.

Fang Jun nodded and said seriously: "Actually, this amount of funding is completely insufficient. Don't worry. It depends on the extent of your research. The further you go in research, the more money you will spend. You can figure it out by yourself when the time comes.

"

"oh"

Xu Mang left Fang Jun's office with a trace of doubt. He did not intend to go back to his apartment. He directly opened the door next door and sat in his office, thinking about the problem of neutrons.

neutron

It seems that the decay of free neutrons only takes about fifteen minutes, and then they will turn into protons, electrons and antineutrinos.

Immediately afterwards,

Xu Mang found two methods to measure the neutron lifetime and downloaded the paper through the library. The first method is the so-called 'bottle' method. In fact, it is to strip the neutrons from the nucleus, then put them into a bottle, and then

Count how many neutrons are left after a period of time.

This method is used by many different laboratories around the world, including Los Alamos National Laboratory and the Laue-Langevin Institute. The lifespan data obtained using this experiment is fourteen minutes and thirty-nine seconds.

The whole world is the same time, there is no difference of half a second.

The second type,

Injecting neutrons directly into a detector that can count the number of protons produced when neutrons decay, the data obtained by this experiment was eight seconds longer.

Impossible!

These two measurement methods are very accurate. How come there is a gap of eight seconds?

magic!

Bang bang bang,

At this time,

Suddenly, there was a knock on the door, which woke up Xu Mang who was swimming in a sea of ​​thoughts, and hurriedly shouted, "Please come in."

The next second,

Wang Jiafu appeared in front of Xu Mang.

"Xu Mang"

"Why did you agree to this project?" Wang Jiafu said seriously: "Don't you know how many doubts there are behind this project? It not only requires a theoretical design, but also a specific experimental plan."

Xu Mang smiled bitterly, why didn't he know this? Unfortunately, is it useful to say this now?

"well"

"Professor Wang, if I don't go to hell, who will?" Xu Mang sighed, turned his head and looked at the scenery outside the window. The sky was gray, just like Xu Mang's inner world, without any color of sunshine.

for a time,

The whole office was filled with sadness, and sadness flowed like a river.

"well?"

"Professor Wang?" Xu Mang asked curiously: "Has Wang Ai called you recently?"

"Been beaten."

"I know that Wang Ai and others have already started to conduct detection." Wang Jiafu showed a hint of gratitude and said to Xu Mang: "Xu Mang, I still need to thank you for this matter. Thank you for giving Xiao Ai this opportunity."

"hehe"

"She fought for it on her own, not from me." Xu Mang smiled calmly and said, "Wang Ai is very good. She is serious, hard-working, and hard-working. There is no choice."

Hearing Xu Mang praise his daughter like this, Wang Jiafu, as a father, was very proud. He could tell that these words were not polite words.
