I really don't want to lie down and win

.at the same time,

"Professor Xu?"

"Your calculation result...is it correct?" Xiao Han asked curiously: "To be honest...we can't even understand what you are doing. It really depends on pure mathematics. , to find an unsolved mystery in the field of physics?"

"Uh..."

"Almost." Xu Mang thought for a moment, then said with a smile: "But we don't need to worry about it, the United States will definitely try to solve this problem, but the final number must be 0.833 femtometers."

"How...how did this come out?" Another woman wearing glasses asked, "Now we are very confused, and we don't know what happened, just watching you writing in front of the blackboard. After a calculation, the result finally comes to a value."

Xu Mang shrugged, and said helplessly, "Then figure out the math."

"..."

"..."

"..."

OMG!

Who wouldn't want to figure it out?But even if he understands it, he probably won't reach half of Professor Xu Mang's height.

"Ugh?"

"That's not right!"

"Professor Xu...we seem to have suffered a lot!" A young man frowned and said with displeasure: "If they take your calculation results for themselves, this... this Isn't it a disadvantage? It's obviously your credit."

"What is the radius of the proton? I'm actually not interested at all. It's as much as it likes." Xu Mang shrugged and responded indifferently: "Let's leave it to them... Finish the last thing tomorrow, the day after tomorrow Let’s go back to China, and I’ve booked first-class tickets for you all.”

What the hell!

I am so happy. Going out with Professor Xu not only increases my knowledge by seeing the world, but also gets a free first-class ticket.

America flies to China!

really expensive!

...

In fact, Xu Mang was completely right. In the evening, all the researchers of Jefferson Laboratory returned to their workplaces. By the way, some of them were called from home to the conference room at ten o'clock in the evening to discuss and discuss with each other. Modify the next experiment.

at first,

In the PR experiment, experimenters fire a beam of electrons at a hydrogen molecule and measure how some of the electrons' motion is deflected, then extrapolate the experimental data to lower electron energies to determine the proton radius.

But this means that some theoretical assumptions must be made that may distort the final results, and perhaps this is where the problem arises.

Theoretical assumptions are wrong...

finally,

After much deliberation by researchers at Jefferson's lab, it was decided that the new PR experiment would inject hydrogen molecules directly into vacuum tubes through which electron beams would pass, rather than retaining hydrogen molecules in metal containers like many previous experiments.

This means that no electrons can hit the metal and interfere with the measurement, while measuring how the electron beam scatters both protons and electrons in the hydrogen atoms.

Distinguishing between these two types of scattering is all about eliminating a major source of error.

The density of hydrogen atoms fluctuates.

"Cough cough!"

"After fighting all night, everyone rested all morning. In the afternoon, we will conduct new experiments."

but,

No one wants to go to sleep,

Everyone is looking forward to the results of the experiment, whether the final figure is 0.833 femtometers.

Without any choice,

The new experiment was carried out all night without any rest, but according to previous experience, this experiment took about three hours, or even more than three hours, from start to finish.

"Say..."

"What do you think the final result is?" A certain researcher asked his colleague beside him, "It's also...you just came here this morning."

"What the hell happened yesterday?"

The confused researcher asked anxiously, "It seems...Professor Xu Mang proposed a brand new concept?"

Brand new concept?

He directly overturned the research results of others.

"Ugh..."

"It's hard to explain. In short, Professor Xu Mang overturned our test data." The researcher said bitterly: "He only relied on the information we provided, and then used purely mathematical calculations to come to the conclusion that the proton radius is 0.833 femtometers."

"what?"

"This...are you telling a story?"

"Story... If this is all a story, it would be great..." The researcher sighed, and said helplessly: "I have a bad feeling... maybe a new PR experiment, The measured result may be ... 0.833."

This is no lie,

What theoretical physicists are best at is using numbers, formulas, ideas, and logic to prove the truth of everything on the tip of their pens. As a world-renowned theoretical physicist, Professor Xu Mang is fully capable of this.

"Hey?"

"Honey... I'm home!"

airport,

Sitting in the VIP waiting area of ​​the airport, Xu Mang made a phone call to Xiaoman who was far away in China, and said with a smile, "My wife... I told you to return with a full load, really... Hehehe, in order to protect us It’s safe, we took a special plane.”

"what?"

"Take a special plane?" Yang Xiaoman was stunned for a moment, and hurriedly asked: "My mother, I bought eight air tickets, do you know how much it cost? This...is it scrapped?"

"no!"
