Chapter 509: Sadness flows down the river (one/three)

what's the situation?
Why are everyone's expressions so frightened?
Xu Mang is a little confused. This neutron is just one of the nucleons of the nucleus. It is generally composed of two down quarks and one up quark. It is not a rare thing. Is it necessary to make such a fuss?
"Xu Mang?!"
"Would you like to be the person in charge of this project?" Fang Jun looked at Xu Mang seriously, and said seriously: "I will give you one last chance. I will answer after you think about it!"
Xu Mang was stunned for a moment, he vaguely felt a little coolness, could it be a pit?
"I..."
"I'm not willing?" Xu Mang asked tentatively, and only each other could hear each other.
"Well!"
"You will be responsible for this project!" Fang Jun said with a smile.
Xu Mang:? ? ?
This...
This really seems like a routine!
At this moment, Xu Mang realized that he had fallen into other people's routines. No wonder he had to call him over. It turned out that he was waiting for him to jump down. The eight-second difference in neutrons... sounds a little weird.
tragedy...
This is a tragedy on earth!
All the people present looked at Xu Mang with sympathy. This project is a bottomless pit, it can destroy anyone's inner world.
"Funding issues."
"A total of about 300 million has been allocated from the above." Fang Jun said: "This money has not been used for special research. If you succeed in the research, you can continue to use the remaining money without turning in again."
what?
Isn't this blood earned? !
Xu Mang has been pitted by funding issues in the past. Most of the funds allocated from the above can only be used for special transfers. If the money is used indiscriminately, it may be severe. However, this time it is not the previous rule. It seems that he has gradually paid attention to the use of funds. Problem.
Although this is a good thing, everyone present doesn't envy Xu Mang, the reason is simple...it can't be done.
quickly,
This meeting is over,
Xu Mang was about to get up and return to the apartment to share this incident with Xiaoman. As a result, he was surrounded by countless people, and there was no gap.
"Xu Mang... don't you know the difficulty of this project?"
"Xu Mang give up... this is an impossible project, Director Fang cheated you."
"You...you promised too early!"
Everyone is persuading Xu Mang to give up this project as soon as possible. There is no need to waste time on an unfinished task. The eight-second difference in neutrons has plagued the entire field of physics for 15 years.
After all, as long as this problem is solved, it is very important to understand the amount of hydrogen, helium and other light elements formed within a few minutes after the Big Bang 13.8 billion years ago.
Many physicists believe that as long as they can further determine the lifetime of neutrons, they can open a new chapter in physics, because determining the lifetime of neutrons can help constrain the measurement of other subatomic particles.
unfortunately,
impossible...
Facing the tide of persuasion, Xu Mang gradually realized that things were not as easy as he believed. If what his colleagues said was true, it was indeed scammed, and the scammed was not so big.
In an instant,
Xu Mang rushed out of the crowd and ran directly to Director Fang's office.
...
"..."
"..."
The two looked at each other. No one spoke. 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. Nonsense.
"Xu Mang... tell you the truth." Fang Jun smiled bitterly: "This project itself was prepared for you. In fact, this project was proposed two years ago, but of course no one wants to study it until Your appearance... only saw a little hope."
"I?"
"I don't know much about neutrons." Xu Mang asked in a daze.

There’s no problem if you don’t understand it now, and you’ll have time to understand in the future.
Fang Jun said,
Anyway...you are responsible for this project. You can do whatever you like. Of course, you can’t go too far. understand."
Xu Mang: (°ー°〃)
That's it,
Feelings need 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 firework show, and he was the person who made the fireworks. Although he knew no one was watching, he still had to do it.
Whether it looks good or not is another matter, at least the fireworks must go to the sky smoothly.
"This..."
"Isn't this a waste of money?" Xu Mang asked.
Fang Jun nodded and said seriously: "In fact, this little funding is completely insufficient. Don't worry... It depends on where your research level is. The more you study, the more the money will be dropped. Then you will see for yourself. Do it."
"Oh..."
Xu Mang left Fang Jun's office with a trace of doubt. He didn't plan to go back to his apartment anymore. He directly opened the door next door and sat in his office, thinking about the neutron problem.
neutron...
It seems that the decay of free neutrons only takes about fifteen minutes, and then they will become protons, electrons and antineutrinos.
Immediately after,
Xu Mang found two methods for measuring the lifetime of neutrons, and downloaded the paper through the library. The first method is the so-called "bottle" method, which is actually to strip the neutrons from the nucleus and put them in a bottle, and then After a period of time, count how many neutrons are left.
This method is adopted by many different laboratories around the world, including Los Alamos National Laboratory and Laue-Langevin Institute. The life data obtained by this experiment is 14 minutes and 39 seconds.
The whole world is one time, no difference of half a second.
The second,
Injecting neutrons directly into a detector that can count the number of protons produced when the neutron decays, but the data obtained from this experiment is eight seconds longer.
Impossible!
Both of these measurement methods have very high accuracy. How can there be a gap of eight seconds?
magical!
Bang bang bang,
At this time,
Suddenly there was a knock on the door outside the room, which awakened Xu Mang, who was swimming in the ocean of thoughts, and hurriedly called for him to come in.
Next second,
Wang Jiafu appeared in front of Xu Mang.
"Xu Mang..."
"Why did you agree to this project?" Wang Jiafu said solemnly, "Don't you know how many doubts are behind this project? Not only does it require a theoretical design, but also a specific experimental plan."
Xu Mang smiled bitterly, why didn't he know this, but is it useful to say it now?
"Ugh..."
"Professor Wang... if I don't go to hell, who will go to hell?" 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 the tint of sunlight.
For a while,
The whole office is filled with sad emotions, and sadness flows down the river.
"Ugh?"
"Professor Wang?" Xu Mang asked curiously: "Has Wang Ai called you recently?"
"Hit."
"I know that Wang Ai and the others have already started to probe." Wang Jiafu showed a grateful expression, and said to Xu Mang: "Xu Mang...you still need to thank you for this matter, thank you for giving Xiao Ai this opportunity."
"Ha ha..."
"She won it by herself, not by me." Xu Mang smiled indifferently: "Wang Ai is very good, serious, hardworking, and hardworking... there is no choice."
Hearing Xu Mang's praise of his daughter, Wang Jiafu, as a father, was very proud. He could hear that these words were not polite.
"Professor Wang."
"By the way, have you ever studied the problem of free neutron decay?" Xu Mang asked curiously.
"Have studied."
"But because of limited technology and ability, I finally gave up on this aspect of research." Wang Jiafu sighed. Suddenly he reacted and hurriedly said: "I still have the research data at that time. I will send it to your mailbox later."
"it is good!"
Send away Wang Jiafu,
Xu Mang was in a daze, thinking about what to eat tonight. After half an hour, he finally thought about eating braised pork. At this time, he received an email from Wang Jiafu in his mailbox and clicked to open it.
After decompression, he got a dozen files. Xu Mang went in and looked at them one by one. The content was quite detailed, but not very comprehensive. They all ended in a hurry.
Difficult!
Hard to be a man,
Harder men are harder!
Xu Mang stretched his waist, then took out his mobile phone. When he encountered some unsolvable problems, he would usually read novels for a while, mainly watching Taibai cats.
"Hey..."
"I owe another five chapters today."
Xu Mang smiled, and after the laugh, there was endless contemplation. He couldn't help muttering to himself: "The white cat owes more than a hundred chapters. He updates diligently every day. I never took a day off. Why not work hard?"
One minute later,
Xu Mang was paralyzed on the chair, with a physics book on his face, he...slept.
Xu Mang: Zzzz
noon,
Xu Mang hurried back to the apartment and saw that Xiaoman seemed to give up on himself. He could still pretend it before. Now he is holding the potato chips in his right hand and delivering it to his mouth while watching the variety show intently.
"Ok?"
"Are you ready?" Xu Mang asked.
Yang Xiaoman gave Xu Mang a blank look, and looked at the phone silently.
"..."
Xu Mang, who was left out in the cold, walked into the kitchen silently, just turned on the gas stove, poked his head out, and asked, "What do you want to eat at noon?"
"Shrimp fried rice!"
"Oh..."
Next second,
Yang Xiaoman can't wait to commit suicide by jumping off the building. Isn't he too hopeless? A bowl of shrimp fried rice was bought.
Forget it...
Quietly looking back at Xu Mang in the kitchen, Yang Xiaoman cautiously walked up and hugged Xu Mang like Xu Mang had embraced her before...Unfortunately, he was too short, his head could only be attached to his back instead of Resting on her shoulders like Xu Mang.
"Don't hold me!"
"Hold so tightly on a hot day..." Xu Mang let go of Xiaoman's hand with a look of disgust, frantically frying the shrimp fried rice in the pan.
In a moment,
Yang Xiaoman exploded on the spot.
...
in the afternoon,
Yang Xiaoman went back to work~EbookFREE.me~ and Xu Mang was thinking about the eight-second difference in the decay of free neutrons, but unfortunately... I don’t have any thoughts, and I don’t even know how to get in. among them.
Later, Xu Mang wondered whether it was because he did not get the funds and his heart was not at ease, which led to a decline in his thinking?
"When you get the money, let's talk about it when."
Words fall,
He picked up a physics textbook on the coffee table, covered his face directly and started sleeping.
"You have a new lawyer's letter, please check it carefully."
The ringing disturbed his sleep,
After a glance at the number, Professor Philip called.
"Xu Mang."
"It's time to meet."
