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 read it carefully.
Lord Kelvin said excitedly: "Awesome! He actually came up with something new in thermodynamics this time!"
Huggins wondered: "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: "If you can't even explain it, then of course there is no problem."
Lord Kelvin can directly serve as a reviewer for the paper and it will be published quickly.
Nowadays, thermodynamics is a hot topic and is rapidly spreading throughout major scientific research institutions.
Boltzmann paid close attention to Li Yu the most, and immediately expressed his support after reading it: "Now 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!"
Boltzmann was somewhat subjective, but he sincerely supported Li Yu. Not only that, he also wrote a congratulatory letter to Li Yu himself: "I recently read my friend's new paper, which has set new highs in the field of thermodynamics. It is really extraordinary.
Special congratulations!”
Later, when he received a reply from the boss, Li Yu immediately wrote back in his own hand: "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 launched experiments based on Li Yu's paper. Of course, this was not a short process and could last for several years.
Planck, another super boss of theoretical physicists, 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 that 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 simply:
"As the absolute temperature approaches zero, the entropy of solids and liquids also approaches zero."
This is the boss'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 look like celebrating the New Year."
Li Yu said: "It's disrespectful. We are all strangers in a foreign land. Let's have a meal together. I've cooked a few dishes. I'm sure you haven't tried them!"
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? Besides, you don't look like a child from a poor family, and it's even less likely that you can enter the kitchen," Lu Bicheng said.
"Then you really don't understand me," Li Yu said with a smile, "Come and have a try!"
He bought meat, eggplant, tomatoes, eggs, chicken and curry today.
Lu Bicheng must have seen the minced pork and eggplant dishes before, but this is the first time I have seen them with tomatoes, scrambled eggs and curry chicken nuggets.
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
The seasoning has been popularized by many "food" bloggers who went to India.
However, 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 a strong taste 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 Yuhui specializes in.
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, and said, "What are they? It's yellow and disgusting!"
Li Yu could only explain it to her again, and then took a bite. Lu Bicheng picked up a piece shakily and said, "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."
"It turns out it's foreign food. You really know something about Western culture."
Well, she doesn't know what globalization will be in the future.
After the meal, Lu Bicheng said again: "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-minded, can't it be more approachable?"
"Easy to approach?" Li Yu thought for a while, "That's right! There's a good thing, and 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 and you can see rainbows anytime and anywhere."
Lu Bicheng was surprised and said: "How is it possible? It is obvious that only rainbows can be seen after rain."
"No, I just 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 also science and a little romance."
Lu Bicheng picked up the prism: "It's unbelievable."
Li Yu said: "I gave it to you. You can play with it when you have nothing to do."
Today's science is really a desert. Not many people know 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 Chinese New Year if he didn’t set off a few firecrackers and light 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. Besides, the ancients have always had the tradition of "respecting writing paper". How can there be so much paper among the people?
Come and make firecrackers.
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 a pile of sesame straw is spread 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 "crackling" sound.
, it sounds like setting off firecrackers. The wisdom of the working people is still very great.
It can also be regarded as a good start to the New Year through the metaphor of "sesame flowers blooming higher and higher".
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 also very rare like the previous lecture notes on basic surveying and mapping and basic ballistics lectures 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, making it 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.
