Li Yu's paper on the third law of thermodynamics was finally sent to the Royal Society. President Huggins didn't dare to open it himself now, so he immediately called Lord Kelvin.
"You can open the letter this time!" Huggins said. Lord Kelvin saw the letter from Li Yu and looked forward to it: "I wonder what new things he can write." He didn't even have time to drink the tea brought by Huggins, so he took out the paper and looked carefully. Lord Kelvin said excitedly: "Awesome! He actually came up with something new in thermodynamics this time!" Huggins said in confusion: "You are already the leader of thermodynamics, what new things can come out of thermodynamics?"
"Look, he actually proposed a new law! It's really incredible!" Huggins is definitely not as proficient in thermodynamics as Lord Kelvin: "You can't even explain it, so of course there is no problem." Lord Kelvin can directly use it as a thesis Reviewer, it will be published soon.
Thermodynamics is now a hot topic and is rapidly spreading throughout major scientific research institutions. Boltzmann paid the most attention to Li Yu and immediately expressed his support after reading it: "Nowadays, most of Europe is discussing Li Yu's paper enthusiastically, and everyone has even been looking forward to the publication of his paper. This is such a brilliant scene!" Bohr Ziman was somewhat subjective, but he sincerely supported Li Yu.
Not only that, he also wrote a congratulatory letter to Li Yu himself: "I have recently read my new paper and reached a new high in the field of thermodynamics. It is really extraordinary. I would like to express my special congratulations!" When he received the reply from the elder, Li Yu immediately wrote back in person. : "Professor Xie! It is my greatest honor to receive your praise." After all, Boltzmann was too old to conduct experimental research.
Other universities or scientific research organizations immediately started experiments on Li Yu's paper. Of course, this is not a short process and may last for several years.
Planck, another theoretical physicist and super boss, could see the problem much faster. After reading the paper, he couldn't help but marveled: "I can't remember how many times I have seen Li Yu's papers. The quality of every paper is so high, it's unbelievable! I really want to go to the mysterious East to see it with my own eyes. Is it true what Marco Polo said about gold everywhere, or is it true what the newspapers say is decadent and backward?" Planck also keenly used his solid statistical theory to point out: perfect crystals of various substances have zero entropy at absolute zero.
Soon he would give Planck's formulation of the third law of thermodynamics: "The change in entropy associated with any isothermal reversible process approaches zero as the temperature approaches zero." Or, to put it simply: "When the absolute temperature approaches zero, the entropy of solids and liquids also approaches zero." This was Da Lao's affirmation of Li Yu.
However, Li Yu cannot yet know the situation in Europe. Here in Tianjin, the Chinese New Year is approaching and many shops are closed. Li Yu has stored a batch of food in advance. Of course, there is no need to store too much. After all, there are still shops in the concession.
Lu Bicheng wrote a Spring Festival couplet and gave it to Li Yu: "This is for you, it should be a bit like celebrating the New Year." Li Yu said: "It's disrespectful, we are all alone in a foreign land, we are strangers, let's have a meal together, I made a few I'm sure you haven't eaten any food!" Lu Bicheng opened her eyes wide: "You actually know how to cook?"
"No?" Li Yu asked.
"How can any university student know this? Shouldn't it just be about learning? And you don't look like a child from a poor family. It's even less likely that the young master will be able to enter the kitchen." Lu Bicheng said.
"Then you really don't understand me very well," Li Yu said with a smile.
"Come and try it!" He bought meat, eggplant, tomatoes, eggs, chicken and curry today. Lu Bicheng must have seen minced meat and eggplant before, but this is the first time I have seen scrambled eggs with tomatoes and chicken curry.
The ingredients Li Yu bought from the British Concession, although now when people think of curry, they think of Indian asan, and there is indeed an Indian soul seasoning in curry: masala.
I believe many people have heard of it. After all, this unique seasoning has been used by many people in India.
"Food" bloggers have become popular. But it was actually the British who brought curry to the world. Since they occupied India, the British have also fallen in love with curry.
Foreigners do have strong tastes and like strong spices. After all, the original driving force for the great voyage was spices.
Since curry itself is a very strong seasoning, curry-related dishes are very simple to make, and these are the simple dishes that Li Yu knows.
Lu Bicheng looked at these two plates of dishes that he had never seen before. Although they were rich in aroma, they had never been seen before, especially the plate of curry chicken nuggets. He said, "What are they? It's yellow and disgusting!" Li Yu could only say again. After explaining it to her and taking a bite, Lu Bicheng shakily picked up a piece.
"Hey, it tastes good! Why haven't I eaten it before?"
"Of course I haven't eaten it before. This is a dish brought over by the British."
"So it's foreign food. You really know something about Western learning." Well, she doesn't know what globalization will be in the future.
After the meal, Lu Bicheng said: "I have carefully read the reports about you these days, but they all seem to be very complicated. Could it be that science is so high-level, can't it be more approachable?"
"Approachable?" Li Yu thought for a while,
"That's right! There's a good thing. I'll show you how simple science is." Li Yu took out a box from the house: "The thing inside is called a prism. It can disperse light. You can see rainbows anytime and anywhere. ." Lu Bicheng said in surprise: "How is it possible? It is obvious that only rainbows can be seen after rain."
"No, I said yes!" Li Yu took out another piece of white paper, let the light pass through the prism, and slightly turned the angle to produce colorful light.
Lu Bicheng couldn't believe her eyes: "It's so magical, there really is a rainbow!" Li Yu said: "This is the essence of light."
"Is this light?"
"This is light," Li Yu said with a smile,
"And it's a little romance of science." Lu Bicheng picked up the prism: "It's unbelievable." Li Yu said: "I'll give it to you. You can play with it when you have nothing to do." The current way of science is really a desert. Ah, not many people know about relatively simple and basic optics.
This year can be said to be the quietest and most ordinary year that Li Yu has ever lived in his life. Perhaps because of this, he can remember it more vividly.
——There is no Spring Festival Gala, no fireworks, not even firecrackers. When Li Yu was a child, it wouldn’t be called the New Year if he didn’t set off a few firecrackers or light up a few firecrackers every year!
It's just that setting off firecrackers is really a luxury nowadays. Not to mention the trouble of making gunpowder, even the firecracker outer paper used to package the gunpowder is difficult to source, not to mention that the ancients have always had
According to the tradition of "respecting calligraphy paper", how could there be so much paper used to make firecrackers among the people. However, during the Chinese New Year, everyone is willing to listen to the noise and step on the hemp straw instead.
Sesame straw is sesame straw. After harvesting and drying, it becomes hollow. Then spread a pile of sesame straw in the yard. During the Chinese New Year, adults and children who get up early will step on it with their feet, and they will make a sound.
The "cracking" sound sounded like setting off firecrackers. The wisdom of the working people is still great.
It can be considered as borrowing
"Sesame blossoms are blooming higher and higher", which means a good start for the New Year. Li Yu only rested for five days during the New Year, and then went back to Beiyang Armed Forces Rapid School to continue taking classes. He wanted to complete the mathematical foundation and mechanical principles courses of the surveying and mapping department before the end of the first month.
Li Yu had more time now anyway, so he helped Wu Peifu organize the lecture notes on basic mathematics and mechanical principles.
Because the lecture notes are in Chinese, they are as rare as the previous lecture notes on basic surveying and mapping and basic ballistics in the late Qing Dynasty and the early Republic of China when science and engineering textbooks were scarce.
Moreover, the content of these two textbooks is also very solid and can be explained in simple terms, which is very suitable for military schools that only need to understand preliminary mathematical knowledge and basic mechanical principles.
Later, it also became an important teaching material for the Armed Forces Academy and the subsequent Baoding Military Academy. It can be said that there are many officers who have read Li Yu's textbooks, and many of them are middle and upper-level officers.
