at first,

Xu Mang didn't want to talk to these people, nor did he want to help them solve any problems. After all, the fees were quite expensive, and Americans might not pay them. However, the looks in their eyes that looked forward to seeing a joke deeply made Xu Mang feel angry.

"Not difficult?"

"Professor Xu Mang seems... very confident?" When the middle-aged man heard Xu Mang's words, he couldn't help but smile and said calmly: "Then I look forward to your performance."

As soon as the words fell,

Everyone present began to talk about it. Everyone put forward their own opinions on Xu Mang's promise to test the interval value of the proton radius. Among them, Professor Smith was one of the few supporters. He believed that Xu Mang could solve it.

"Professor Henry?"

"Do you think Xu Mang can solve it?" Professor Smith asked.

"solve?"

"The mystery of the proton radius?" Henry Millen showed a hint of disdain and said calmly: "Professor Smith... I know that Xu Mang is a member of your Princeton Astrophysics Association, but you cannot treat him because of this relationship.

Blindly believe it?"

Professor Smith showed a smile: "How about we make a bet? If Xu Mang's final calculated value is infinitely close to the number in your experiment, can the Physics Association provide us with a huge sum of money for research next year?

Funding?”

"Can!"

"No problem!" Henry Mirren nodded and said seriously: "If it cannot be achieved, what can we do?"

"The Princeton Astrophysics Database provides free services to members of the Physical Society." Smith said seriously: "Can Professor Henry do it?"

“Pretty good.”

Henry Mirren smiled and said: "Then we will definitely win."

"..."

Facing the confident Henry Mirren, Professor Smith felt a little helpless. One blindly believed in Xu Mang, and the other blindly denied Xu Mang. However, each had their own opinions. First of all, he admitted that there were unsolvable problems in the calculation of the proton radius mystery.

, but when the person who solved it is Xu Mang, this question needs to be put in quotation marks.

at this time,

Xu Mang was eating the apple pie on the plate. In fact, he wanted to eat the kind of apple pie in McDonald's, but what was served here was really a round pie... with strips on it. No wonder some people regard apple pie as a staple food.

After this one, I was completely full.

"Professor Xu Mang..."

"How could you agree to such a thing?" Cui Yue frowned, feeling helpless about what was about to happen. She knew it was a trap, but Xu Mang jumped in. Didn't he deliberately create a joke?

"Is there any problem?" Xu Mang asked curiously: "It's really not difficult!"

"..."

"Professor Xu Mang... This is a problem that the Americans deliberately came to run against you. How could it not be difficult?" Cui Yue smiled bitterly: "Forget it... As of now, I can't say anything more.

Anyway, you can figure it out yourself, I can't help you much in this matter."

"oh."

"Don't be nervous...it's really not difficult." Xu Mang smiled and silently cut the apple pie on the plate.

Ten minutes later,

Xu Mang completely ate the pie and sat on the chair with a satisfied look on his face. He had eaten a lot for dinner, including two pieces of filet mignon, an apple pie, a turkey leg, and a bowl of vegetable and fruit salad. He was almost done with it.

Pin it to the throat.

"Professor Xu Mang?"

"Is it almost time to start?" The middle-aged man couldn't wait.

"What to start?"

"I just finished eating, why should I take a rest?" Xu Mang said angrily: "Why are you so anxious? Who the hell dares to rush me again, be careful I have to pay more! I can do anything.

Gotta come out.”

"..."

"..."

"..."

Not only the American people were stunned, but also the members of the Chinese delegation were shocked. Good guys... Standing on American soil and mocking Americans in front of their faces, this kind of thing is just Xu Mang

The professor can make it.

That kind of middle-aged man's face turned red, but he didn't dare to refute anything. Just as Xu Mang said, he could do anything.

"Professor Xu?"

"You... do you really have no problem?" A young member of the delegation sitting next to him asked cautiously: "I just searched the Internet for related content and found... I found that the proton radius has been changing.

Small."

"As for the value of the radius of the proton, it has been constantly overturned by others, and then a new value is re-established, Professor Xu Mang... Even after you provide a value, I think it will still be overturned by others in the future." This young man

said.

"overthrow?"

"Isn't it normal to overthrow?" Xu Mang didn't think so, and said calmly: "Being able to overturn previous theories shows that science is constantly progressing. What's the problem with this? I'm not invincible..."

Xu Mang is not worried about the future. Instead, he is more open-minded. He hopes that others will overturn some of his theories. Only by constantly overturning and re-establishing can he reach the end of science.

"Sorry...everyone"

"Excuse me."

The words fell,

Xu Mang left the scene and went to the bathroom.

Standing in the bathroom, there was a no smoking sign next to it, but Xu Mang didn't care whether it was forbidden or not, he needed a cigarette to help him organize his thoughts on the proton problem.

The mystery of the proton radius,

How to solve it?

"Hello?"

"Honey...do you have anything to do with me?" Xu Mang sat on the toilet and asked with a smile: "We just had a video call, and you miss me again so soon? That's it...International long distance calls are quite expensive, I

Very few."

"snort!"

"Don't be so sentimental, I'm too lazy to miss you." Yang Xiaoman said angrily: "The tickets are sold out...at noon the day after tomorrow, damn...did you already know that there would be no tickets tomorrow?"

"Hey hey hey."

"Then I'll hang up first."

Xu Mang hung up the phone directly, not to mention... After talking to Xiao Man on the phone, he felt a lot more relaxed.

Returning to the hall, Xu Mang did not sit in his seat. Instead, he came to several blackboards and looked at the contents on them. For a while, he really couldn't find any solution.

Are you about to start?

At this time,

Everyone's eyes were fixed on Xu Mang, looking forward to what would happen next.

proton,

The content above all uses the method of particle beam impacting atoms to record data on how particles are scattered by atomic nuclei. This seems to be unusable at all... There is absolutely no room for manipulation. Is it necessary to use another method?

In today's world, there are ways to measure the size of a proton. The first is particle beam impact, while the second is based on the movement of electrons around the nucleus. Since some electron orbits pass through the protons in the nucleus, the size of the proton will

Affects the bonding strength between electrons and atomic nuclei.

Using spectroscopic technology to accurately measure the difference between the energy levels of each electron, the radius of the proton can be estimated.

pity...

Even the second method has been blocked, and the US has not provided relevant data.

"well..."

"It's a little difficult!" Xu Mang sighed, thinking of the system in despair.

"The system... uses pure mathematical calculations to calculate the exchange value of the proton radius?"

[After identification by the system, the exchange value of the proton radius is calculated: 10000 (physical skills)]

[After identification by the system, the exchange value of the proton radius is calculated: 30000 (mathematical skills)]

oh?

It seems that there is a small tool for mathematics.

Xu Mang found that mathematics skills consumed more than physics skills. There should be content in mathematics that he did not know, and the value was only 30,000. It might be an extension of a certain formula.
To be continued...
