Chapter 145

The last question is not conventional, but original by Xu Kaiqing.

Scientists at his level are naturally qualified to work out a problem, and it is difficult to find a problem!

For example, Xu Kaiqing's original problem appeared in the Romanian mathematics masters the year before last.

Yes, it's not a physics competition, but one of the world's top math competitions.

Laymen don't understand the doorway, so they like to join in the fun. Some people openly question Xu Kaiqing's personal ability and problem-solving level online by using his big V identity in order to attract attention and rub heat.

The whole process focused on the point that "physicists can also work out mathematical problems", and criticized the domestic academic atmosphere as a thorough one.

The process quoted scriptures, sharp words and incitement.

But in the end, they were ridiculed by the whole network as "ignorant". Who says physicists can't work out mathematical problems?

Planck is not only a physicist, but also has great attainments in literature and music.

Leonardo da Vinci, not to mention physics, chemistry, mathematics, astronomy, painting, architecture... Can be called a decathlon.

Someone once asked how good Newton's mathematics was. A: if his contribution to physics is 1, his contribution to mathematics is definitely no less than 0.9.

As an interdisciplinary doctor and doctoral director, Xu is not only a leader in domestic physics, but also a VIP in the fields of mathematics and chemistry.

Who dares to question his authority and professionalism?

Facts have proved that Xu Kaiqing can really afford the identity of "topic setter".

At the Romanian masters of mathematics, this problem became the final battle on the way for 26 participating countries to win the championship. Finally, country y succeeded in solving the problem, worked out the optimal solution and won the gold medal.

After the competition, this problem, as a key research example, was included in imdp magazine and known to mathematics lovers all over the world.

Since then, Xu Kaiqing has not provided any original topics for international discipline competitions.

I didn't expect it again today!

"It's also an ox break to let old Xu go out in person."

"Can I get rich overnight if I steal the title and sell it?"

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

"Sorry to interrupt.

"It is estimated that the difficulty of the problem is not small. Can Jiang Fuyue and Huo Fanjin do it?"

"I don't know if Jiang Fuyue can do it, but Huo Fanjin probably has no hope."

The first question just made a small question. When she finished writing the second question, she would do the third question. I don't know it's going to be a long time.

"According to the iPho schedule, Huo Fanjin's speed is normal after 3 hours of theoretical examination?"

"Normal is normal, but... I can only say that there is no harm without comparison."

With Jiang Fuyue and Zhuyu in front, Huo Fanjin can only be gloomy no matter how well he performs.

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

"What happened?"

"That's it? No?"

"Didn't the document load?"

On the projection cloth, there is only one sentence about the third question——

Explainthephysicsofquasi-crystalswithdatasupport.

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

Jiang Fuyue was stunned when she saw the problem.

There are no scenarios, no parameters, or even specific problems.

A "physical" is empty and abstract, which makes people confused.

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

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

Supported by data.

Or physics problems, or need to use formulas, still need to carry out a lot of operations.

It's just that the entry point is very random, and it's a huge test for anyone to choose.

The reaction of the audience was more intense——

"Can this be called a question?"

"He doesn't know me, and I don't know him, thank you."

"What is quasi crystals?"

"Quasicrystal."

"What is 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."

"Ah? What do you mean?"

"Quasi crystals is a crystal structure. The arrangement and combination of atoms in quasicrystals are not arranged symmetrically according to repeated cycles, and the arrangement of atoms is between crystal and amorphous. The person who discovered it was Daniel shechtman, who became the winner of the Nobel Prize in chemistry in 2011."

"Oh, I see... Wait! What do you mean the Nobel Prize?"

"Chemistry Award."

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

"No. that's why I said quasi crystals are not in the field of physics."

But it appears in the iPho test!

Also discuss physics!

Huo Fanjin hasn't finished the first question, but listening to the comments and exclamations from around, she still couldn't help but look at the projection cloth.

At this glance, he was stunned on the spot.

If one or two questions are still within her ability, but it takes a little more time to solve them smoothly, then the third question is no different from heaven's book for her.

Her eyes were no less dazed than those who watched the excitement.

At this time, she suddenly wondered whether Jiang Fuyue's reaction was as confused as herself, or whether she frowned and thought hard about 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 down a chemical formula with a marker in his hand——

Al57.0+xCu39.5-xRu3.5(x=0，2.5，5，7.5，10)andAl62.0Cu34.0+yRu4.0-y(y=0，0.5，1.5)[1]

"What is she doing?"

Someone under the stage asked Huo Fanjin's questions.

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

Jiang Fuyue turned a deaf ea
