Yes, but not entirely. ”
“What are quasi-crystals?”
“Quasis-crystals are a type of crystal structure. The atomic arrangement in a quasicrystal is not arranged in a repetitive periodic symmetric pattern. Instead, the atomic arrangement is somewhere between that of crystals and amorphous crystals. The person who discovered it was Daniel Shechtman, who won the Nobel Prize in Chemistry in 2011.”
“Oh, I see … Wait! What Nobel Prize did you say?”
“The Chemistry Prize.”
“Uh! Isn’t the person we are meeting today a graduate student in the Department of Biology?”
Why did you ask about physics and chemistry?
” Mr Gus has just reminded me that his next questions are not limited to biology.”
“Hiss! To be honest, this question is still too difficult for undergraduates.”
“She answered the first few questions very well, but she was unlucky and was targeted by Dempsey … ”
“Is it difficult?” Dempsey said calmly, “Of course, you can also give up answering.”
Myrna raised her eyes and looked directly at him: “Do you have a whiteboard and markers?”
The key point of this question is – “with data support”!
Supported by data.
Examine interdisciplinary abilities.
“Yes.” Dempsey raised his hand, signaling the staff to get ready.
Soon, the whiteboard was in place and the pen was handed to her.
Myrna turned around and wrote down a chemical formula.
Then, using the chemical formula as a starting point, we analyze the atomic structure of the quasicrystal.
There are two important principles among them, namely the icosahedron principle and the golden mean principle.
Under the action of these two principles, the simplest quasicrystal structure model can be obtained, which can explain all the details of the high-resolution image of Al-Mn quasicrystal.
The above is knowledge in the field of chemistry.
Then, she deduced the formula for quasicrystals from the aspects of fractal geometry, pattern sequence, correlation measure, and correlation dimension.
Among them, the pattern sequence is further discussed at the 2nd order, 3rd order and kth order respectively.
The above belongs to the field of mathematics.
Looking at the whiteboard in front of her filled with English and numbers, Myrna immediately switched to the next one.
At this point, the question really begins to enter the core step, which is the physical explanation.
Myrna divides it into two parts, namely theoretical physics and applied physics.
The former mainly includes three theorems, seven formulas, and sixteen derived sub-theorems.
Not only did she write it all down, she also set up her own scenarios and used specific numbers to verify its authenticity. When she encountered a situation that she could not bring in, she simply proved it directly.
If you see a mountain, climb it. If you can’t climb over it, dig a hole. It is simple and crude, but quite effective.
As for the applied physics part, there is more …
Effect of deformation and heat treatment process on properties of 00Cr12Ni9Mo4Cu2 martensitic stainless steel.
Quasicrystal enhanced microstructure and properties of Mg-Zn-RE alloy.
The diffraction properties of one-dimensional Fibonacci-type quasicrystals, the deep supercooling of Al72Ni12Co16 alloy and the solidification behavior of decahedral quasicrystals, etc.
Myrna wrote them down one by one, and soon the second whiteboard was also finished.
Dempsey signaled the staff to continue preparing the third whiteboard.
Finally, Myrna ends with three conclusive derivation formulas, leaving behind a digital model that can be brought in for verification, which is a perfect ending.
She put down her pen and looked at Dempsey : “That’s my answer.”
After a while, the man’s serious face finally showed a hint of smile: “Thank you for your answer, you can leave now.”
Myrna unclenched her fists, bowed politely, and turned to leave.
When another examiner saw her leaving, he half-jokingly asked, “Wen Bai, are you too strict with this student? Even the third-year graduate students couldn’t answer the question correctly.”
Dempsey said calmly: “Only excellent students can make people want to explore their upper limits.”
It turns out that she has more potential than he thought.
…
After coming out of the examination room, Myrna received a WhatsApp message from Joanna .
A week ago, the two made an appointment to celebrate together after the interview, and the address was the French restaurant they often went to.
Myrna opened the map software and prepared to call a taxi.
Suddenly, a familiar voice came from behind.
” Myrna ? It’s really you.”
Vita is also here for the re-examination today, in the afternoon.
She came here early thinking she would get familiar with the environment and not be nervous, but she didn’t expect to meet Myrna .
“You are … ” Vita Howard looked her up and down.
Myrna said calmly, “Interview.”
“You passed the written test?!” She was so surprised that she almost broke her voice.
“Um.”
“How many points?”
“412.”
“You are the first in our professional written test?!”
Myrna was slightly surprised: “Really? I didn’t pay attention … ”
“Heh, why are you pretending? Is it interesting?” Vita pulled the corner of his mouth with a hint of sneer.
She only scored 392 and barely made it to the interview. I didn’t expect Myrna to have done so well.
Myrna died unjustly, she really didn’t pay attention to the rankings.
After receiving the text message about the re-examination and confirming the time, she didn’t care about it anymore.
Usually the announcement list on the school’s official website would be sorted from high to low based on the written test scores, but Myrna had never logged on to take a look.
“If you don’t believe me, forget it. I have something else to do, so I’ll leave first.” She didn’t bother to explain. What Vita thought was not important to her at all.
Without Ansel , there would be no need to please his family anymore.
If you love a house, you will love everything about it. If you don’t love it anymore, everything related to it is bullshit.
“Wait–” Vita took the initiative to stop her.
Myrna turned around and asked, “What else?”
“Hey! Are you coming out after the interview?”
“Um.”
Vita’s eyes flickered. “Were the questions difficult? What did they ask? Were there many questions related to my major?”
Myrna raised an eyebrow, “You … want me to reveal the question?”
“You don’t have to say such harsh words. I’m just sharing my experience. It’s not that serious. Besides, the people who ask you questions may not ask me.”
“Yes,” Myrna nodded. “Since you know that everyone’s problems are different, you should understand that there is no need to share, right?”
“What’s more,” Myrna raised her eyes and looked at her word by word, “We are competitors now. Why do you think I will help you?”
“You–” Vita was speechless for a moment.
In her subconscious, Myrna is still the woman who would go to great lengths to please all the relatives and friends around her brother for the sake of her brother.
But the reality is, Myrna has already started a new life.
She let go so freely and walked away so decisively, but what about her brother?
Even when he was hospitalized for gastric bleeding, he still hoped that she would come to visit him. Even when he was in a coma, he kept calling her ” Myrna “. In recent months, he has become even more silent and depressed.
Myrna is too ruthless!
Vita looked at her coldly. The simple formal suit couldn’t be more ordinary, but it made her look very energetic.
Especially those eyes, which were shining, bright and cunning.
She is living so well without her brother!
