Mo Ran stood on the podium and looked at Professor Stern a little embarrassed, Professor Stern nodded and smiled at him, and then a voice came from the emperor's message: Mo Ran, you are only visible to me now, the students can't see you for the time being, don't be too restrained, it's not time for you to appear, I will liberate your vision later, so that other students can see you.

"But Professor, is this class important? I'm ...... now I care more about Lei Ying. Mo Ran said.

"Mo Ran, this class is very important to you! It's also very important for Lei Ying, don't worry, it only takes half an hour. Professor Stern comforted him with kind words, and Mo Ran calmed down.

"Students," Professor Stern said to the students present, "who can tell us about their understanding of the concept of superfluid?" ”

"Me!" A classmate raised his hand, and Professor Stern motioned for him to stand up.

"Professor, when the temperature of liquid helium drops to 2. (-270.98c), it changes abruptly from the general fluidity of the original liquid to "superfluidity": it can pass through very small holes or slits (about 100,000 centimeters of linearity) that cannot even pass through gases without any hindrance, and it can also "crawl" along the wall of the cup - out of the mouth of the cup. We call a superfluid state of matter a superfluid, and an object with a superfluid state of matter is called a superfluid. ”

"That's right," Professor Stern nodded, "which student can talk about the state of the art of superfluids?" ”

"Professor, I'll come." Another student stood up, obviously these students had just done their homework, not only learned the knowledge in the knowledge bag, but also searched the Internet for other cutting-edge news, and memorized it, of course, for the genius students of the canonized seminary, memorizing it is simply a necessary skill for home.

"In the year 259 of the starry sky calendar, the Hong element was discovered, which can become a superfluidity at minus 150 degrees. In the 470th year of the starry calendar, the discovery of the Ru element marked the beginning of the real practicality of superfluidity, because the Ru element can be pressurized by different superconducting currents and arbitrarily converted into superfluid between minus 30 and 60 degrees Celsius. Since then, there have been new elements, new superfluids have been discovered, but the performance of the Ru element is still the best. According to legend, the creation work of the devil genius Yuansu [Adam] mecha has the element of Ru in it. ”

When he heard the word Adam, Mo Ran chuckled in his heart, Adam has the element of you in it, which means that it may have other forms? Have you only used one of its forms?

Professor Stern nodded and smiled: "Very good, the students have a lot of understanding of superfluidity just now, but I am talking about the most cutting-edge research on superfluidity, not this knowledge that we have known for a long time but have not usually noticed." This time, what I want to hear is not the knowledge you are learning and using in the knowledge bag, but the knowledge that you have studied on a daily basis. ”

Speaking of this, the audience suddenly fell silent, and Professor Stern shook his head, this is the reason why the solar system is decaying! Come to think of it, these cutting-edge technologies are constantly being studied by other galaxies in other countries, and the most elite students on Earth are ignorant of them, so what reason is there for the solar system to revive and become strong?

For a long time, the Great Chinese Empire only cared about resource trade, army building, the number of mechas, and domestic stability, and they had a sense of resistance to new things in their hearts for foreign technologies that were much more powerful and advanced than their own, because to make them accept new things is equivalent to saying that the old things are gone, and let them abandon their vested interests and have mastered the knowledge they have mastered for many years.

This is like saying that a middle-aged cadre who has been a leader for many years suddenly transfers him to a new department to be a junior brother and re-study, because that department is much more advanced and excellent than his original department, how can this leading cadre agree?

"The latest research on superfluids is applied to living organisms, Professor." Mo Ran said softly, and when he learned the astonishing fact that he was an elemental container, he used K's authority to climb over the wall and read many scientific research papers outside the Great China Empire.

Stern smiled at Mo Ran with understanding, and said, "The latest research on superfluids is applied to living organisms, which is already a very common thing in the Dark Spirit Country, which is good at elemental control. ”

The audience was in an uproar at the professor's remarks, which they had never heard before, the Great Chinese Empire practiced a high-pressure rule and closed diplomacy, and domestic trade, negotiations and networks with other countries were strictly controlled, not to mention sensitive topics such as cutting-edge technology.

"Well, let's all think about it, how useful superfluids are, the originally airtight armor and city walls, even the smallest atoms of hydrogen can't pass through guò, but there are some liquids that can pass through guò armor, what a miraculous thing. Have you ever wondered what it would be like if a human being could also be transformed in a superfluid state and a normal state? Professor Stern said in high spirits that whenever he talked about what he was good at, he went from being a gentle professor to a passionate orator, who could talk loudly, make generous speeches, and open the sky.

"But how is this possible, Professor? We have known for a long time that the elements that make up the human body are just calcium, sodium, potassium, magnesium, carbon, hydrogen, and oxygen atoms. Some students couldn't help but ask.

"Two thousand years ago, it may have been so, but since human cells can fuse metamorphosis factors, this situation has changed, but there has never been a pioneer who has the courage to boldly imagine to connect this qiē, and now, the Dark Spirit Kingdom has become the first person to eat crabs, they have achieved a little in this area, and I am fortunate to learn something, and today, I will share what I know with you."

After Stern said this, the audience immediately became a sensation, and every student's face was full of expectant expressions, sure enough, the classes of the three saints are different, not just boring theoretical classes, and now, the professor is finally going to get serious! The application of superfluids to living organisms and even the human body, imagine how amazing this is.

"Mo Ran, pay attention." Professor Stern's voice came, "I'll do a little real yàn in a moment, and all the numbers jù of real yàn will be synchronized to you, and I hope these numbers will solve your confusion about the term element container." ”

"Professor, how do you know I'm ...... I care? ”

"Don't forget, I've lived for decades, and I still have the ability to read words. But no matter what you think, I still say that the elemental container is a creation of God, a higher and more powerful being than humans. ”
