Open an aircraft carrier to fight against Japan

Now that the contract has been largely approved, the remaining details were quickly finalized. Three days later, the two parties formally signed the contract. According to the agreement between the two parties, Will stayed in Ryukyu as the early technical instructor.

Lin Yuan hoped that Will could start training as soon as possible, but Will said: "This is very difficult, because I have to translate a batch of materials for you to read. I also know that some people in your Ryukyu can speak English, but I don't think anyone can translate them. These professional materials are translated because it is too difficult for you.”

Lin Yuan almost couldn't laugh out loud when he heard this. He managed to hold back his laughter and said, "Give us the materials, and we'll show you the translations. If it's suitable, we'll start the training as soon as possible."

Will agreed nonchalantly, thinking to himself, "There's no way these people understand this stuff."

Lin Yuan took the materials and went to find the scientists and engineers on board, hoping they could help translate and tell everyone what Will said as a joke. The others laughed and didn't take it seriously, except Su Zhengming became angry when he heard it, and said, "Call that foreign devil for me, and I will discuss professional issues with him!"

Lin Yuan laughed quickly and said, "Mr. Su, don't be as knowledgeable as this foreign devil. You have more important things to do. We will produce a lot of things in the future, and we will need a lot of materials. I hope you can give us a rough idea. Make a list, I know this matter is very difficult, and only you can handle this burden."

Su Zhengming smiled and said: "You really found the right person. The average scholar has reached our level. The depth of knowledge is enough, but the breadth is gone. You will never find a scholar like me who has both. There's a second one out."

Lin Yuan repeatedly said yes.In China, very few people with science and engineering backgrounds are poor in English, because they have to read a lot of English materials, so many scientists and engineers worked together, and the materials were translated soon.

With the help of Shangtai, the first batch of [-] students was quickly recruited. These people all have certain cultural knowledge, at least know how to read and write, which is not easy in this country.So it didn't take a few days before the training started.

In the first class, Lin Yuan approached Liu Jinqiu and said, "Mr. Liu, please go and listen to it, and see how the craftsmanship of this era is different from ours."

Liu Jinqiu smiled and said: "Don't call me Mr. Liu, just call me Teacher Liu. I have taught in college all my life, and I feel so comfortable when I hear others call me teacher! Since the captain said so, I must go."

Lin Yuan said: "Mr. Liu, if that foreign devil has something to say that is wrong, you must bear it."

Liu Jinqiu laughed and said, "I'm not as knowledgeable as that foreign devil."

Thermodynamics is the basis of almost all metallurgical sciences, so Will's first class started with some basic concepts of thermodynamics. He said: "What is heat? We often see such examples in our lives, such as , a pot of hot water will gradually cool down, why is this? Because heat is a substance that has no weight and can flow freely in objects. That’s right, why does hot water cool? It’s because heat flows from places with high density to places with low density.

Hearing his narration, Lin Yuan knew that this was the "caloric-mass theory" that once dominated the history of thermodynamics. "Thinking that heat is a form of expression of object motion was proposed in the early 19th century, but it will take another 100 years to completely overthrow the theory of heat and mass.

At this moment, Lin Yuan saw Liu Jinqiu slapping the table hard, and said loudly, "You are talking nonsense!"

Wil was taken aback for a moment. When he saw this unremarkable old man sitting in the classroom, he thought he was a handyman. His gentlemanly demeanor did not allow him to throw the old man out. Now this old man actually slapped him on the table. Yelling, he suddenly felt a burst of surprise!

How did Lin Yuan know: This Mr. Liu is usually easy-going, but when it comes to academics, he is more serious than Su Zhengming!

Liu Jinqiu stood up and said like teaching a child who failed to count from one to ten: "How can heat be a substance? Let me ask you: if heat is a substance, why does friction generate heat?"

Seeing the old man asking himself aggressively, Will couldn't help feeling a little flustered. He said, "Debris is produced during the rubbing process, 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 while and said, "Probably."

Liu Jinqiu said: "How can heat be generated? When soaked in ice water, the temperature is zero degrees, and the density of the heat mass is uniform, so no matter how much friction there is, no heat will be generated."

Will really panicked now, he understands the problem, this is an out-and-out paradox!It is wrong if he answers that ice cubes do not generate heat, because friction will bring out heat.

At this time, Liu Jinqiu stepped onto the podium and said: "Students, don't be misled by the theory of heat and mass. Everyone must remember that there has never been such a thing as heat and mass in this world. Heat, in the final analysis, is a kind of exercise." Manifestations!"

Liu Jinqiu was standing on the podium at this time, as if he had returned to the university he was familiar with. He reached out to get the chalk, only to realize that there was no chalk in this era, so he retracted his hand resentfully, leaning on the table and preaching: "Students, after we understand the nature of heat, let's learn about the smelting of iron and steel. Iron and steel are inseparable from heat, so where does the heat for iron smelting come from? It is produced from the combustion of coke! This heat is used to Melting iron ore, there are many types of iron ore, ferric oxide, that is, magnet, ferric oxide, etc., where does the melting process take place? In the blast furnace, after the molten iron is produced in the blast furnace, we After some desulfurization and dephosphorization of the molten iron, the molten iron is sent to the steelmaking furnace, so that steel is produced..."

He explained the general process of steelmaking in an in-depth and simple manner, and everyone was fascinated. At this time, he said: "The basic theory is like this. In actual production, there will be many technical problems. Everyone, copy the information I have on hand."

That document was translated by Lin Yuan's scientists and engineers. Liu Jinqiu stood on the stage and frowned slightly, and said, "About this document, there are many mistakes in it. For example, this According to a document, the content of silicon in molten iron can be slightly higher, because silicon can be used as a heating agent, but it is not true, the lower the content of silicon, the more beneficial it is for dephosphorization and desulfurization, and it can reduce the generation of slag!"

Like this, Liu Jinqiu, from a modern perspective, commented one by one on the deficiencies in the steelmaking process at the end of the 19th century. When he came to the fifth point, he saw Lin Yuan gesturing to him again and again, and he smiled embarrassedly and said: : "Okay, let's stop here today."

Will on the side was completely overwhelmed. He couldn't figure out why an old Ryukyu man knew so many things. While everyone was leaving, he ran over to Liu Jinqiu and asked, "How do you know so many things?"

Lin Yuan smiled and said, "Because he is Chinese."

Will sighed quickly: "Oh! The magical East! The amazing Chinese!"
