Chapter 199: I'm thinking about how to reject them
Qiao Sen was also a little surprised when he heard Xu You's words .
"They actually sent you an email? Let me see!"
After carefully reading the information in the email, Qiao Sen's expression became a little subtle.
"Teacher Qiao, is this really an email from the U.S.-China Academic Exchange Committee?"
Qiao Sen nodded and said, "Yes, it is indeed that academic organization. It is not easy to be invited by them. This is also a great recognition of you."
It seems that academic organizations in the United States also attach great importance to Xu You's theory.
In addition, this also shows that even the experts in the United States may not be able to fully understand Xu You’s theory.
Indeed, if he hadn't listened to Xu You's explanation up close, even Qiao Sen wouldn't have understood much of the theory.
Although Qiao Sen's ability may not be as good as that of some of the top experts in the United States.
But the gap won't be that big.
This can only mean that it is very difficult to understand the theory when the theory itself is so complex and the theoretical expression is so concise.
Not to mention, putting this theory into practice.
But Qiao Sen also knew.
If Xu You had not published this paper on PRL, it would have been recognized by many top experts and received a significant response in the world academic circle.
The project of searching for new high-temperature superconductors would not receive such attention from the country.
"Xu You, what do you think about this matter?"
Qiao Sen did not rush to help Xu You make a decision, but first asked Xu You what he thought.
"Teacher Qiao, I'm thinking about how to reject them."
Qiao Sen couldn't help but laugh when he heard Xu You's answer.
Sure enough, faced with such temptation, Xu You remained as calm as before.
If it were other students, after receiving an invitation from an academic organization of this level, they might have already started booking a flight to the United States.
"Yes, rejection is also a science. After all, you will inevitably continue to submit papers to American journals in the future, so you still have to maintain good relations with their academic circles. The reason for rejection must be sufficient, and the other party must be able to accept it and not have any objections."
Next, Qiao Sen gave Xu You some advice on how to politely decline their invitation.
At this point, Qiao Sen is still more experienced than Xu You.
This is the art of organizing language by an old professor.
…
The United States across the ocean.
Sage Camara anxiously waited for Xu You's reply.
This time, it was Kamala's suggestion to invite Xu You to the United States for exchanges through the U.S.-China Academic Exchange Committee.
Before, Kamala was confident that he could fully understand Xu You’s theory within a few months.
But it turns out that if you want to fully understand this theory, you can't just accumulate time.
Kamala is still confused about many of the details.
Those words such as "obvious", "easy to obtain", "easy to prove", "no need to elaborate" and so on really stumped Kamara.
These are clearly some logical relationships that are beyond comprehension no matter how hard one tries.
Why use these words to express it?
Kamala wished she could meet Xu You right now and ask him these questions in person.
Even if he didn't eat, drink or sleep, and asked questions for days and nights, Kamala would not feel bored.
At this time, Kamala suddenly received a message from the US-China Academic Exchange Committee.
"Did Xu You finally reply?"
But when Kamala was eager to see the news that Xu You accepted the invitation.
But they found to their regret that Xu You rejected their invitation.
"Can't attend because of academic reasons? Oh, what a pity."
Xu You's tone in his reply was very sincere, without any hint of deliberate refusal.
Kamala didn't think much about it and just thought that Xu You really couldn't come to the United States because of these reasons.
"In that case, I'll go to China to visit Xu You when I have the chance." Kamala thought.
At this age, Kamara has no ambitions to discover new high-temperature superconductors.
Kamala just wants to thoroughly understand Xu You's theory.
Kamala will regret it for the rest of her life if she cannot understand it.
…
Shortly after Xu You declined the invitation from the US-China Academic Exchange Committee.
The other side also replied to Xu You with new information .
The general meaning is that he regrets that Xu You could not come.
If Xu You has time in the future, you are always welcome to participate in academic exchanges.
Xu You did not have such an intention, but in writing, he still politely thanked the other party for the invitation .
During this period, the material experts of the project team are still carrying out intensive material preparation work.
These materials experts are much better than Xu Zhou in terms of both qualifications and abilities.
Although Xu You could not help much in material preparation, he learned a lot of valuable experience just through his internship in their laboratory these days.
Finally, after going through many difficulties.
The first new material with possible high-temperature superconducting properties has been successfully prepared.
According to the prediction of software simulation, the superconducting critical temperature of this material reaches 150K.
Although this temperature is still not enough to achieve a superconducting state using dry cooling.
But if it is really as predicted by the software simulation, it will set a new record for the critical temperature of normal-pressure superconductors.
More importantly, it can also verify the practicality of Xu You’s simulation system and be used in the subsequent search for superconductors.
"Next, let's prepare to test the superconducting properties of the material."
This work is the professional area of Qiao Sen and Xu You.
Qiao Sen and Xu You brought the materials back to the condensed matter physics laboratory of Ji University to prepare for measuring the superconducting properties.
In order to witness this moment of success for the first time.
Academician Xing Shuping and many other professors also went to the Condensed Matter Physics Laboratory of Jilin University.
This time, it was still the monotonous and tedious task of measuring resistance.
But the meaning behind it cannot be measured by simply measuring resistance.
Xu You and Qiao Sen both had serious expressions on their faces, and they did not dare to relax easily for any simple step.
"Let's start preparing to cool down." Qiao Sen said.
Because the predicted superconducting critical temperature is relatively high.
Using liquid nitrogen, the required temperature conditions can be achieved.
After making all the preparations, Xu You began to cool down the system.
At this time, the temperature of the system and the resistance of the material can be displayed synchronously on the computer connected to the system.
At first, as the temperature dropped, the material's resistance did not change significantly.
However, when the temperature of the system drops to around 150K.
The resistance of the material suddenly dropped sharply.
