After Rebirth, I Am the White Moonlight of All The Big Brothers

The last question is not a conventional one, but was originally created by Xu Kaiqing.

A scientist of his level is naturally qualified to ask questions, and it is difficult to find a question!

For example, Xu Kaiqing's original problem appeared in the Romanian Mathematics Masters Competition last year.

Yes, not a physics competition, but one of the top math competitions in the world.

Laymen don't understand the way, so they like to join in the fun. Some people use the identity of a big V to publicly question Xu Kaiqing's personal ability and question-making level on the Internet in order to gain attention and gain popularity.

He insisted on the point that "physicists can also solve mathematical problems" throughout the whole process, and criticized the domestic academic atmosphere so thoroughly.

The process quoted the classics, and the wording was sharp and provocative.

But in the end, it was ridiculed by the whole Internet group for "ignorance". Who said that physicists can't solve math problems?

Planck was not only a physicist, but also highly accomplished in literature and music.

Not to mention Leonardo da Vinci, physics, chemistry, mathematics, astronomy, painting, architecture... It is a decathlon.

Someone once asked how good Newton's mathematics was. Answer: If his contribution to physics is 1, then his contribution to mathematics is definitely not less than 0.9.

As an interdisciplinary doctoral and doctoral supervisor, Mr. Xu is not only a leader in the domestic physics field, but also a distinguished guest in the fields of mathematics and chemistry.

Who dares to question his authority and professionalism?

Facts have proved that Xu Kaiqing is indeed worthy of the identity of the "questioner".

At the Romanian Mathematics Masters Competition that year, this question became the final battle of the 26 participating countries on their way to the championship. In the end, Country Y successfully solved the problem, calculated the optimal solution, and won the gold medal.

After the competition, this question was included in the "IMDP" magazine as a key research example, and was known to mathematics enthusiasts all over the world.

Since then, Xu Kaiqing has not provided any original questions for international academic competitions.

I didn't expect it to happen today!

"It would be a good idea to let Elder Xu go out in person."

"I stole the title and sold it, can I get rich overnight?"

"Oh, people have to buy a full set of questions. Do you have a reference answer?"

"..." Sorry to bother you.

"It is estimated that the problem is not difficult, can Jiang Fuyue and Huo Fanjin do it?"

"I don't know if Jiang Fuyue will do it or not, but Huo Fanjin is probably hopeless."

The first question was just a small question, and when she finished writing the second question, she did not know that the third question would be the year of the monkey and the month of the horse.

"According to the IPhO schedule, the theory test takes 3 hours. Is Huo Fanjin's speed normal?"

"Normal is normal, but... all I can say is, there is no harm without contrast."

With Jiang Fuyue Zhuyu in front, no matter how good Huo Fanjin performed, he could only be in the dark.

"Hey! No, look at the last question..."

"what's the situation?"

"That's it? No more?"

"The document didn't load, did it?"

I saw that on the projection cloth, about the third question, there was only one sentence——

Explain the physics of quasi-crystals with data support.

Based on data, the physical properties of quasicrystals are described.

Jiang Fuyue was stunned when she saw the title.

There are no scenarios, no parameters, not even specific questions.

The phrase "physicality" is vague and abstract, which makes people confused.

At first glance, I thought I was going to write a popular science essay.

But Jiang Fuyue quickly grasped the point - "with data support"!

Backed by data.

It's still a physics problem, still need to use formulas, still need to do a lot of calculations.

It's just that the entry point is very arbitrary, and it is a huge test for the person to choose at will.

And the reaction of the audience was even more intense——

"Can this be called a title?"

"It doesn't know me, and I don't know it, thank you."

"What are quasi-crystals?"

"Quasicrystal."

"What's that?"

"Who knows? We haven't studied subdivision physics."

Someone shook his head: "This is not the scope of discussion in the field of physics."

"Huh? What does that mean?"

"Quasi-crystals is a crystal structure in which the arrangement of atoms in a quasicrystal is not symmetrically arranged in a repeating periodicity, and the arrangement of atoms is between crystalline and amorphous. The person who discovered it was Daniel Sheikh. Terman, for which he was awarded the Nobel Prize in Chemistry in 2011."

"Oh, so... wait! What kind of Nobel Prize did you say?"

"Chemistry Prize."

"My God, shouldn't it be a physics award?!"

"No. That's why I said quasi-crystals are not part of the discussion in physics."

But it happened to appear in the IPhO test questions!

Also talk about physics!

Huo Fanjin hadn't finished the first question yet, but listening to the constant discussions and exclamations around her, she couldn't help distracted and glanced at the projection cloth.

Just this moment, he was stunned on the spot.

If one or two questions are still within her ability, but it will take a little more time to solve them smoothly, then the third question is tantamount to a book from heaven to her.

The dazedness in her eyes was no less than that of those watching the fun in the audience.

At this time, she was suddenly curious about Jiang Fuyue's reaction. Was it just as at a loss as she was, or was she frowning and trying to figure out how to solve the problem?

Thinking so, Huo Fanjin did look at her.

Jiang Fuyue, who had been standing still for a long time, suddenly moved, stood in front of a clean whiteboard, and wrote a chemical formula with the marker in her hand——

Al57.0+xCu39.5-xRu3.5 (x = 0, 2.5, 5, 7.5, 10) and Al62.0Cu34.0+yRu4.0-y (y = 0, 0.5, 1.5)[1]

"What is she doing?"

Someone in the audience asked the question in Huo Fanjin's heart.

Even Yan Zhenfeng couldn't help reminding her: "This is a physics competition!"

Jiang Fuyue turned a deaf ear...

Three shifts, two thousand words.
