Shocked by this number, Director Li couldn't help but look slightly moved, and couldn't help but ask.
What's even more unexpected is that just after he came back, he did such an earth-shattering thing...
The title of the paper is very short, so short that it can be read out in two seconds.
If this was really the case, he could indeed imagine Director Li's surprise at that time, but what he couldn't imagine was how did Lu Zhou get this thing out in five minutes? !
Since the birth of the discipline of computational materials science, theoretical calculations of complex systems have faced two major challenges. One is how to transform accurate theoretical treatments at the microscopic level into direct descriptions of mesoscopic and macroscopic level phenomena, and the other is how to further improve the accuracy of the density functional method that is the basis of existing large-scale calculations.
Scholars like Dyson are in the minority after all. As their knowledge reserves increase and their understanding of science continues to increase, most people will gradually lose their seemingly unrealistic illusions about science.
When Director Li returned to Beijing with the sample, he helped Lu Zhou register the patent ownership through the fast track, and then asked someone to send it to Hangke Group.
"Then he gave this thing to you?" After swallowing a sip of tea, Academician Yuan's old face turned red, and his excited tone was full of confusion and disbelief, "What the hell?"
"Yes, is it such an exaggeration?"
The Young's modulus of nylon rope is about 1.4GPa, and the unit of Young's modulus of this SF-1 super fiber has changed from GPa to TPa. Even taking into account possible deviations caused by a series of factors such as technology, this This statement is not an exaggeration at all.
"I didn't pay attention. We are engaged in materials engineering, and the research direction is not mathematics and physics. Why pay attention to his paper?"
"Of course I've seen this before, what's wrong?"
…
"I know what you want to ask, but I don't know either. I just heard that the model is built using computational materials science, and then quickly verified in the laboratory... Ignore these things for now. Please tell me about this thing first. easy to use?"
However, the amount of information in it is not generally large!
Looking dumbfounded at Academician Yuan standing at the door, Director Li's face was filled with surprise that was no less astonishing than his.
"No, that... is still a bit too exaggerated."
"But how did he-"
On the Mizuki Forum.
"No exaggeration at all."
He seemed to feel that what he was doing was a bit unethical. Academician Yuan Huanmin hesitated and finally spoke.
"What are you saying is too exaggerated?"
"It's also possible!"
Seeing the moved look on Director Li's face, Academician Yuan Huanmin shook his head.
If he remembered correctly.
"What the hell?! Is it true? How long has it been since he studied materials? Didn't he go to study physics later?"
What’s even more surprising is that the name on this paper is actually Lu Zhou!
Looking blankly at Director Li sitting opposite, Academician Yuan nodded first, then shook his head.
Professor Stanley was obviously not the only one who was shocked.
"What he published was a paper on materials!"
And not just that!
No matter how surprised he was at this moment.
"Are you so awesome..."
After wallowing in his imagination for a while, he seemed to feel that his idea was too exaggerated. Academician Yuan quickly shook his head and rejected his idea.
"It is no exaggeration to say that if you use this thing to make fabrics or clothes, it will be a body armor without ceramic linings. If you use this thing to make a rope, it will have the tensile strength of an aircraft carrier arresting cable. We also have other physical properties. I haven’t tested it, but in terms of tensile strength, I can’t imagine a stronger material than it!”
However, compared to the space station at the Lagrange point and the scientific research station on Mars, this thing is still a bit beyond his imagination.
"Didn't you ask me to ask Academician Lu some time ago if he could get this thing out? This time I went to Jinling and asked casually, and then he gave it to me."
That bag of samples should have been delivered to the old academician yesterday afternoon...
"He resigned from the position of chairman of IMCRC some time ago... Let's not talk about this anymore. Go and take a look. When our professor just saw that paper, he was so surprised that he couldn't close his jaw!"
"It's just easy to use?" Meeting those eager eyes, Academician Yuan smiled, shook his head, sighed softly and said, "Have you ever seen a nylon rope?"
"Okay, okay."
Standing up from his desk, Director Li pulled Academician Yuan to sit down opposite each other on the sofa in front of the coffee table, and explained.
"Ahem, please drink some water to calm down first." After a slight cough, Director Li looked at the secretary standing in the office with an equally surprised look on his face, and said, "Xiao Li, go and give Academician Yuan a cup of tea. "
"A thousand times?!"
"That SF-1 super fiber! Which unit made it?!"
Hearing the first part was okay, but when he heard the second part, Academician Yuan Huanmin, who was drinking tea, almost spit out the water he just drank.
Is this what people do if they half-talk
"It's not just so awesome," Academician Yuan sighed, "What limits its use is only our imagination, who knows..."
Nodding dumbly, the secretary named Xiao Li quickly walked to the cupboard where the electric kettle was placed. It didn't take long before he put two cups of tea on the coffee table in the office.
The limitations of implicit functional density in describing van der Waals forces, metallic bonds, etc. have always been a major headache for researchers in computational materials science.
However, now this problem is actually solved so easily by a paper posted on Arxiv
"What I'm saying is, maybe even a space elevator..."
"I know you are surprised. In fact, I am more surprised than you. From the time I asked him if he was sure about it to the time he threw the finished product in front of me, it took less than five minutes. You can imagine the look on my face at that time. His expression... is probably even more exaggerated than yours now."
It's so terrifying!
Almost the next morning after the samples were delivered to Hangke Group, Academician Yuan Huanmin rushed to the Bureau of Science and Industry and found Director Li's office without stopping.
No one expected that his resignation from the IMCRC Board of Directors would actually pave the way for his return to the materials science community.
"not sure?"
Everyone was shocked by this unexpected news.
From the last achievement to the present, many people have lost count of how long it has been since he has been engaged in research in materials science.
"Have you read that paper? It's the one Lu Shen recently uploaded to Arxiv!"
Just when Academician Yuan found his office, the entire materials science community was shocked by a paper!
Looking at the confused expression on his face, Director Li could probably understand his mood, so he couldn't help but smile bitterly.
"Replace the polyamide fiber twisted into nylon rope with the super fiber you gave me yesterday," Academician Yuan said in a serious tone while looking at Director Li. "The tensile strength can be increased at least a thousand times."
Being tickled by this guy's betrayal, Director Li suddenly became anxious and asked.
Hearing the word "space elevator" from Yuan Huanmin, an old academician who has been studying the aerospace field for decades, is quite strange for Director Li.
As the saying goes, the more you know, the less you imagine.
