Xie Yingying still remembers Wang Dalu.
After learning the situation, Xie Yingying was a little confused.
This is ridiculous! It's like something out of a movie, using a fake passport to sneak out and actually thinking you're a secret agent!
Is there anything more bizarre than a business visa with all the necessary paperwork and proper procedures being blocked by a fake passport?
Xing Baohua was even more upset after hearing this. He slammed his fist on the table in anger and called a guard to take the security personnel to bring Wang Dalu and the others back.
Of course, with the intervention of a formal organization, the two detained individuals could be released early, and the subsequent administrative penalties could be handled internally by their respective organizations.
If you have connections in Shandong and Qinghai, you don't really need to be constrained; there are many ways to suffer less.
Anyway, this kind of thing can't be filed or uploaded to the system; it all depends on the local authorities.
Afterwards, Xing Baohua asked Xie Yingying to pack up and prepare to go to the Capital Hospital.
Xing Baohua then rushed back to the villa, packed his luggage, and prepared for his business trip the next day.
When he returned, he still heard them arguing. Xing Baohua glanced at them and went back to his room. After he finished tidying up, he had just come out when Zhang Dongshuo called him over.
"What are you arguing about again? Can't you two just talk it out calmly?" Xing Baohua advised.
"We are discussing the temperature of the superconducting carrier, whether it is used in high-temperature superconductors or low-temperature superconductors," the physics expert said.
"Is there any difference?" Xing Baohua asked.
Last year, scientists Zhu and Zhao successively developed yttrium-barium-copper-oxygen materials, raising the critical superconducting temperature to over 90K and breaking the temperature barrier of 77K for liquid nitrogen.
Therefore, according to the current global classification of superconductors' critical temperatures, high-temperature superconductivity and low-temperature superconductivity are both defined at 77K. Temperatures above 77K are called high-temperature superconductors, and temperatures below 77K are called low-temperature superconductors.
Xing Baohua looked bewildered. He said he understood electrons, but when he tried to explain physics to him, he realized that electrons and physics were completely unrelated, two different categories.
However, in quantum computing, it has surprisingly become a major category of electronics dominated by physics.
What is 77K? I'm not a professional and don't really understand some of the terminology. Most people say "K" to mean kilobytes. If your salary is in K, that's easy to understand. If you say KB, that means kilobytes, which you'll understand even better.
If Xing Baohua hadn't been given a heads-up, he would have had no idea that K represented temperature.
The physics expert patiently told Xing Baohua a short story.
There are three or four types of temperature representations on Earth. One is Fahrenheit, which is used to describe a person with a fever of 80, 90, or even 100 degrees Celsius. Don't be surprised, this refers to the Fahrenheit unit of measurement.
Another is Celsius, which is the temperature we use now. Thirty-four or thirty-five degrees Celsius is considered hot, while in Northeast China it's minus ten or twenty degrees Celsius. You need a stick to pee in there.
So let's talk about the K, which stands for Kelvin. Whether it's Fahrenheit or Celsius, these are names given by people, and K is also derived from Kelvin's name.
Just like how Watt uses W, Newton uses N, and Volt uses V.
Furthermore, Kelvin set zero at absolute zero. This is called thermodynamic temperature, also known as the absolute temperature scale.
Let's set zero degrees to absolute zero, which is the lowest temperature in the universe -273.15°C. Suppose boiling a kettle of water requires 100 degrees Celsius, but in Kelvin measurement, it's converted from 0 degrees Celsius to 273.15K, and then 100 is added.
In other words, it takes 372.15K to boil a kettle of water.
Therefore, the near-temperature of a superconductor, the standard of 77K, is -273.15 + 77K = -196.15 degrees Celsius.
Xing Baohua understood. Regardless of the value of 77K, whether it's high-temperature superconductivity or low-temperature superconductivity, it's still above minus 100 degrees Celsius.
Therefore, the theoretical value they are arguing about lies in the superconducting carrier after liquefaction in the liquid nitrogen temperature range.
A huge container is used to hold liquid nitrogen. The superconductor is placed in a low-temperature zone and quantum particles are implanted.
Then, Chen Shuoyue said that the physicist was misleading people, taking the opportunity of theoretical deduction to bring up magnetism.
It is now known that superconducting energy can be divided into three main categories: high-voltage applications, low-voltage applications, and diamagnetism.
Quantum chips are based on weak electricity, and according to physicists, magnetic properties must also be considered in applications of weak electricity!
After their explanation, Xing Baohua was completely bewildered. How could something as seemingly simple as electronics have produced such a complex system that was beyond his knowledge?
In electronics, anything that is charged is magnetic; otherwise, every connecting wire would have a magnetic ring, making it antimagnetic.
Besides, the physicist isn't wrong; even weak electricity can have magnetism! They've considered everything thoroughly, so why are we arguing?
Chen Shuoyue's next few words left Xing Baohua speechless with surprise.
Didn't I just say that superconductivity is divided into three main categories? They are all derived from each other.
You'll encounter electromagnetism in your research on low-voltage applications, but the magnetism here is based on information from both overseas and domestic references. The magnetism produced by a superconductor, when it reaches a strong magnetic field, is called a magnetically enclosed body.
What does this mean? According to Chen Shuoyue, if 235U undergoes a fusion reaction, the internal temperature would be around one or two hundred million degrees Celsius. Currently, there are no materials on Earth that can contain these temperatures. Therefore, under normal circumstances, it would release energy and create a giant mushroom cloud!
However, some have proposed a theoretical approach, which most scientists agree on: Enclosing and confining the plasma in ultra-high temperatures using magnetic confinement, then gradually releasing its energy—similar to puncturing a balloon with a pinhole to let air out.
So this is controlled hydrogen fusion.
