Top Student

Xu You believes that even those seniors in the physics department may not be able to discover the problem.

After another series of calculations, Xu You finally released the accurate energy level data of hydrogen atoms.

And through the slight deviation, the radius of charge distribution inside the proton is re-revised.

After comparing the data, Xu You found that the accuracy was much better than before.

After calculating a more accurate result, Xu You finally felt the full sense of accomplishment.

"However, compared with the long-range subtraction scheme used by supercomputers, the accuracy value is still much worse."

After all, the human brain is not a computer, no matter how smart it is, it is impossible to reach the computing speed of a computer.

At this time, Xu You still felt a slight sense of loss in his heart.

Even the results of his own calculations are already very accurate.

But Xu You knew that compared to the super-calculation results, it was still too rough.

"What's the matter, did you encounter any problems?"

Seeing Xu You's appearance, Lou Song asked curiously.

"You can't say that, it's still made. It's just that the result is not so accurate. Suddenly thinking that the human brain will never be better than a computer, I feel a little hopeless."

Xu You told Lou Song what happened just now.

"Hey, there is no way. This is the impact of technological development. I understand the feeling of despair, just like the despair when Kejie and Alphagou played chess."

The former Go artificial intelligence could not even play some slightly stronger amateur players.

But with the advancement of artificial intelligence algorithms, even top chess players can only be defeated in the face of artificial intelligence.

"However, I think with the strength of the two of us, we may be able to make this result more accurate."

At this time, Lou Song suddenly changed the topic.

"Huh? Really, Lou Song?"

"I think you can try it. As long as you can list a more accurate equation, I will solve the rest. Because from then on, it is a mathematical problem."

Xu You was overjoyed when he heard this.

It sounds like there is a play!

If you can really use the power of the two of them, make this calculation more accurate.

That would definitely be a very refreshing thing.

"If you can sum up all the data and equations, then I will try to edit a set of algorithms to see if I can calculate more accurate results. Of course, if the amount of calculation is too large, my computer may also crash."

Lou Song's computer is equipped with a 12th-generation Core processor, which is quite capable of dealing with ordinary calculations.

"Okay, then I'll see if I can rearrange the equation."

Xu You basically knew nothing about computer algorithms.

Fortunately, with the genius Lou Song around, Xu You saw the hope of solving this problem.

In the next few days, the two spent almost all their spare time on solving this problem.

The process of solving the problem was not as easy as expected.

In fact, whether it is Xu Youlie's equation or the algorithm edited by Lou Song, there is no problem.

However, within the limited computing power of the computer, a large number of calculations cannot be completed.

Only when the accuracy is guaranteed as much as possible, can the equation be simplified.

In the end, after several revisions of the plan by the two of them.

Finally, a feasible plan was formulated.

As for Lou Song's computer, after dozens of hours of computing.

Finally calculated the final result.

"Great! This time it's only two standard deviations from the experimental result!"

Compared with the previous error of five standard deviations, the accuracy this time has undergone a qualitative change.

Seeing this ideal result, Xu You and Lou Song couldn't help clapping their hands in celebration.

Although this is just a question randomly posed by Wang Xiangwu, it is much higher than the competition question in terms of difficulty and application value.

No matter how difficult the questions of the competition are, they are only carefully designed by the question maker to test the students' ability.

Compared with the actual problem, it is a completely different matter.

For real scientific research problems, there is not only no standard solution, but even the problem itself may be wrong.

This is also the first time that Xu You and Lou Song have had close contact with scientific research.

After the excitement, Xu You began to sort out the entire problem-solving process.

Because I don’t know whether to use computer algorithms to assist calculations is within the rules.

Xu You deliberately listed both methods in the process.

And in the part of the computer algorithm, Lou Song's name was left.

After sorting out the entire problem-solving process, Xu You added an attachment and sent the file to Wang Xiangwu's mailbox.

...

In the evening, after a long day of work.

Wang Xiangwu remembered the assignment of homework before.

"Let's see if any students can make it."

To distinguish between the teaching and research component of the work.

Wang Xiangwu has two different mailboxes, which receive two different types of emails.

Wang Xiangwu logged into the mailbox left for the students and checked the email.

"Yes, there are still many students who have done this problem."

In Wang Xiangwu's mailbox, there are more than 30 unread mails.

Wang Xiangwu opened them one by one to check everyone's answer to this question.

Just as Wang Xiangwu expected.

In the vast majority of emails, the inaccurate data on the energy level of Miao hydrogen atoms was not considered.

But this cannot be blamed on the students, after all, this is a problem beyond the outline.

And in the class, Wang Xiangwu just mentioned it in one sentence, and didn't explain the details in depth.

Of course, even so, this is not a wrong result.

It can only be said that the accuracy is relatively low.

"Not bad! There are still a few students who have considered this issue."

Finally, Wang Xiangwu saw a few students and carefully considered the energy level of hydrogen atoms.

Successfully calculated results with only five standard deviations from the experimental values.

"This year's students are pretty good."

It stands to reason that such a difficult topic is already at the level that only master students can achieve.

Even for the students of Ji University, it is already very remarkable to be able to solve such a problem in their sophomore year.

"Huh? This is..."

At this time, a unique solution process appeared in front of Wang Xiangwu.

It is different because the content of this answer is much more complicated than that of other students.

The previous process was similar to those of the students. They all took into account the problem of the energy level error of hydrogen atoms, and calculated the answer with an error of only five standard deviations.

But another solution attached later made Professor Wang Xiangwu frown.

"There is such a method to simplify the equation?"

Comparing thistle and UConn long-range subtraction programs.

The equation listed in the student's solution is obviously much simpler.

Such an equation, although compared with the long-range subtraction scheme, the accuracy value will be worse.

But at the same time, it can also greatly reduce the amount of calculation.

You don't even need a supercomputer, even a better home computer can calculate the result.

"You even edited the algorithm yourself? This kid is really not simple!"
