Three days later, the two sides formally signed the contract, and according to the agreement between the two parties, Will stayed in the Ryukyus as the early technical instructor.

Lin Yuan hoped that Will could start the training work as soon as possible, but who knew that Will said: "This is very difficult, because I have to translate a batch of materials to show you, and I also know that some of you in the Ryukyus can speak English, but I don't think anyone can translate these professional materials, because it is too difficult for you." ”

Lin Yuan almost didn't laugh out loud when he heard this, he barely held back his laughter, and said, "You give us the information, we will show you the translation after we finish translating, you see that if it is appropriate, we will start training as soon as possible." ”

Will agreed without hesitation, and thought to himself, "There's no way this group of people can understand these things." ”

Lin Yuan took those materials, and then went to find the scientists and engineers on the ship, hoping that they could help translate, and tell Will's words to everyone as a joke, and the others laughed when they heard it, and they didn't take it to heart, but Su Zhengming became angry when he heard it, and said: "You help me call that foreign devil, and I will discuss professional issues with him!" ”

Lin Yuan hurriedly smiled and said: "Old Su, don't be like this foreign devil, you have more important things to do, we have a lot of things to produce in the future, and we need a lot of materials, I hope you can give us a list of them, I know that this matter is very difficult, and only you can carry this burden." ”

Su Zhengming said with a smile: "You really found the right person, ordinary scholars have reached our level, the depth of knowledge is enough, but the breadth is gone, a scholar like me who takes care of both, you can't find a second one." ”

Lin Yuan said yes again and again. In China, people with science and engineering backgrounds rarely speak English poorly, because they have to read a lot of English materials, so many scientists and engineers work together, and the materials are quickly translated.

With the help of Shang Tai, the first batch of fifty students was quickly recruited, and these people all had a certain amount of cultural knowledge, at least literacy, which was not easy in this country. So it didn't take a few days for the training to begin.

In the first class, Lin Yuan specially found Liu Jinqiu and said, "Old Liu, please listen to it too, and see how the craftsmanship of this era is different from ours." ”

Liu Jinqiu said with a smile: "Don't call me Liu Lao, just call me Teacher Liu, I have taught in the university all my life, and I heard others call me teacher, not to mention how comfortable it is!" Since the captain said so, then I will definitely go. ”

Lin Yuan said: "Teacher Liu, if there is anything wrong with that foreign devil, you can take care of it." ”

Liu Jinqiu smiled: "I won't be like that foreign devil." ”

Thermodynamics is the foundation of almost all metallurgical science, so Will's first lesson began with some basic concepts of thermodynamics, and he said, "What is heat? We often see such examples in our lives, for example, a basin of hot water will slowly become cooler, what is this for? Because heat is a substance that has no weight and can flow freely in an object, the density of this substance is temperature, and the density of heat and mass is high when the temperature is high. This is because the heat mass flows from a place with high density to a place with low density.

Lin Yuan heard his narration and knew that this was the "thermal mass theory" that had once occupied a dominant position in the history of thermodynamics, which believed that heat was a substance, which was later overthrown by the "thermal theory", which believed that heat was a manifestation of the motion of objects, and proposed that it was in the early 19th century, but it would take another hundred years to fully overthrow the thermal mass theory.

Lin Yuan saw Liu Jinqiu slap the table at this time, and said loudly: "You are talking nonsense!" ”

Will was stunned for a moment, when he saw this inconspicuous old man sitting in the classroom, he thought he was a handyman, and his gentlemanly demeanor did not let him throw the old man out, and now this old man actually slapped the table and yelled at him, he suddenly felt a burst of surprise!

Where did Lin Yuan know: This Liu Lao is usually easy-going, but when it comes to academics, that seriousness is even more serious than Su Zhengming!

Liu Jinqiu stood up and said like a child who couldn't count from one to ten: "How can heat be a substance? I ask you: If heat is a substance, what does friction produce heat? ”

Will couldn't help but panic a little when he saw the old man asking himself aggressively, and he said: "Debris is produced during the friction, and the heat comes out with the debris. ”

Liu Jinqiu asked again: "Then let me ask you, if I use a transmission mechanism to rub two ice cubes soaked in ice water, will it generate heat?" ”

Will thought for a moment and said, "I think so." ”

Liu Jinqiu said: "How can it be hot? When immersed in ice water, the temperature is zero degrees, and the density of the heat mass is uniform, so no matter how much you rub it, it will not generate heat. ”

Will was really panicked at this moment, he understood the problem, this is an out-and-out paradox! It would also be wrong if he replied that the ice cubes would not heat up, because friction would bring the heat out.

At this time, Liu Jinqiu walked up to the podium and said: "Students, don't be misled by the theory of heat mass, everyone must remember that there has never been such a thing as heat in this world, heat, in the final analysis, is a form of movement!" ”

Liu Jinqiu stood on the podium at this time, as if he had returned to the university he was familiar with, he stretched out his hand to get the chalk, only to find that there was no chalk in this era, so he retracted his hand stupidly, held the table and said: "Students, after we understand the nature of heat, we will learn the smelting of iron and steel, ironmaking and steelmaking are inseparable from heat, so where does the heat of ironmaking come from?" Produced from the combustion of coke! This heat is used to melt iron ore, there are many types of iron ore, ferric oxide, that is, magnets, ferric oxide, etc., where does this melting process take place? In the blast furnace, after the molten iron is produced in the blast furnace, we carry out some desulfurization and dephosphorization treatment of the molten iron, and then send the molten iron to the steelmaking furnace, so that the steel ......"

He explained the general process of steelmaking in depth and concisely, and everyone was fascinated by it, and then he said: "The basic theory is like this, and in actual production, there will be many technical problems, so everyone will copy this information I have at hand." ”

That information is the one that Lin Yuan organized scientists and engineers to translate, Liu Jinqiu stood on the stage and flipped it slightly, and couldn't help frowning, he said: "About this information, there are many errors in it, for example, this information says that the content of silicon in molten iron can be slightly higher, because silicon can be used as a heating agent, but in fact, the lower the content of silicon, the more beneficial it is for the treatment of dephosphorization and desulfurization, and it can reduce the production of slag!" ”

Liu Jinqiu was like this, standing in a modern perspective, commenting on the shortcomings of the steelmaking process at the end of the 19th century, and when he reached the fifth point, he saw Lin Yuan gesturing to him again and again, and he smiled embarrassedly: "Okay, let's stop here today." ”

Will on the side was completely impressed, he couldn't figure out why an old man from the Ryukyus would understand so many things, and when everyone left, he ran over and asked Liu Jinqiu: "How can you understand so many things?" ”

Lin Yuan said with a smile: "Because he is Chinese." ”

Will hurriedly sighed, "Oh! Magical Oriental! Amazing Chinese! ”
