Chapter 260 Three Impractical Sextants

"Hey, third brother, don't be afraid. This thing is a kind of machine developed by Director Zhao. You only need to add water and charcoal to it, and the machine can run, and then generate huge power. This kind of machine is called We call it a steam engine, and this kind of train is just an application of the steam engine." Li Yin said, introducing Zhao Yifan who was beside him to Li Ke and others.Although Yifan is only a girl, she is the dean of the Dengzhou Academy of Sciences. In Li Yin's eyes, the other party is more important than the entire city of Dengzhou. aoye.

The three Li Ke brothers were very surprised when they heard this. They turned their heads to look at the rumbling steam locomotive, and then at the petite Yifan. They really couldn't imagine that the big guy was made by this girl.

Speaking of which, the speed of the train was really slow. I saw the train rushing out of the small woods just now, but I waited for a long time before the rumbling train reached Li Yin and the others.However, the train didn't stop. Instead, it passed them and turned around before stopping.

"Third Brother, Seventh Brother, Eighth Brother, how about we go up and take a ride together?" Li Yin invited with a smile. This train has been running for many days, and there has been no major problem. The speed is slow, so there should be no danger, so Li Yin wanted to ride it himself to try it out.Capital Datang 263

"Then what are you waiting for? I'll go up first!" Li Zhen was impatient for a long time, and when she heard Li Yin's words, she was the first to rush up.Because I knew that Li Yin and the others were going to take the train, no one else was on the train today. When Li Yin boarded the carriage, he found that the layout of the carriage was very similar to that of later generations of buses. Rows of wooden stools were fixed in the car. Although it looks a little crude, it can seat more people.

The four of Li Yin boarded the car first, and each found a seat by the window and sat down, accompanied by Lu Hong and Zhao Fu's father and daughter. Originally, Li Yin wanted to invite Yang Yan and Cai'er to come too, but he thought about it. Seeing Yang Hao's condition, he couldn't be too excited, so he didn't invite him. Although Cai'er was very interested, she knew that her father couldn't go, so she stayed in the city to accompany him.

After everyone was seated, the train finally started slowly with the sound of the whistle.Li Yin has long been used to riding in various motor vehicles in his previous life, so naturally he didn't feel much.On the contrary, Li Ke and Li Zhen felt very novel, excited as the train slowly accelerated, and even came to ask Li Yin about the working principle of the steam engine. The machine that eats coal and runs on water is really amazing!

Although Li Yin didn't know much about machinery, he was enough to fool Li Ke and the others, so he talked about the working principle of the steam engine and the difficulties he encountered when he asked Yifan to design and manufacture the steam engine. Apart from Li Yin and Yifan, even Zhao Fu didn't know much about these things, so while admiring the scenery outside the car window, everyone seemed to be very leisurely while listening to Li Yin talk about the history of the development of steam engines.

However, when the train was driving towards the port, Li Yin found an extremely interesting phenomenon. For example, when the train was moving forward at full speed, a few people would suddenly run over on the concrete avenue parallel to the railroad track, and quickly catch up with the train. He grabbed the door of the carriage and wanted to get in the car, but was driven off by the guards of the palace at the door.

Seeing this situation, Li Yin laughed out loud. Yifan has said just now that this train usually travels between Dengzhou and the port, and it is free for people to ride. It is estimated that these people are the same as usual. It's a ride, after all, although the speed of the train is slow, it is at least a little faster than walking, and it can save some energy.

It's just that when Yifan saw this situation, his face turned slightly red. As the main designer of the train, the speed of the train is only a little faster than walking, let alone comparing the speed with the carriage. The strength of the carriage is that as long as the train does not break down and there is enough fuel and water, it can run without stopping.

After taking the train back and forth between Dengzhou and the port, Li Yin praised Yifan greatly and encouraged him to make persistent efforts to increase the speed of the train. In addition, regarding Yifan's plan to build a steam engine ship, Li Yin also immediately approved, and also suggested that the car and boat could be refitted. First, the car and boat were more suitable for steam engines.

For Li Yin's suggestions, Yifan carefully wrote them down, and discussed some details with Li Yin. Although these Li Yin can't help with specifics, they can provide some novel ideas and steam engines. The future development direction of the ship, and these are exactly what Yifan needs.

"My subordinate Wei Gong, see Your Highness!" Wei Heizi, who is in charge of the Dengzhou Ship Design Institute, saluted Li Min respectfully in the main hall of the Prince Qi's Mansion in Dengzhou City.In addition to the two of them in the hall, Zhao Fu was also here, and there were seven or eight young people standing opposite Zhao Fu.

"Dean Wei doesn't need to be too polite!" Li Yin said with a smile.Since Wei Gong became the dean of the Ship Design Institute, he has become a leading figure in Dengzhou's shipbuilding industry. No one dares to call Wei Heizi's nickname anymore. In front of outsiders, he is still called his position.

"Thank you, Your Highness!" Wei Gong stood up after hearing this, and at the same time he looked at the seven or eight young people next to him suspiciously, guessing their origins.

"President Wei, I invited you and Zhao Biejia here at the same time. The first thing is to introduce these new colleagues to you." Li Yin said, pointing to the seven or eight young people next to him and said, They are all disciples of Taishi Ling Li Chunfeng, the leader is Xie Chun, this is Hua Guang..."

Li Yin introduced these seven or eight young people. After Li Chunfeng successfully developed the sextant, he sent disciples like Xie Chun to Li Yin and asked them to follow Li Yin to Dengzhou. The method is taught, as for how to teach it, that is Li Yin's problem.

However, when Li Yin came to Dengzhou last time, people like Xie Chun did not stay, but followed him to Taiwan. Even when Li Yin was in Taiwan, people like Xie Chun continued to go south by boat, and continued to measure in the area of ​​Guangzhou, almost all the important seaports were measured. These data are very useful. These data will also be compiled into teaching materials when using the method.

After introducing the person, and then the two sides greeted each other, Li Yin continued: "When Li Taishiling came to Dengzhou, I asked him to help design an instrument. This instrument is used for positioning at sea. It can be said As long as you have this kind of equipment, you don't have to worry about getting lost at sea!"

"Sea positioning instrument! Your Highness, there is such a sharp weapon in this world?" Li Yin's voice just finished, Zhao Fu and Wei Gong were both surprised.One of them is a master shipbuilder, and the other has been an official by the sea for many years, so they naturally know the seriousness of getting lost at sea, but they didn't expect that the instrument for positioning at sea can still be solved?

"Hehe, don't be surprised, my lords. I heard from the teacher that this kind of sextant was proposed by His Highness, and then the teacher and others painstakingly developed it for more than a year. It took countless painstaking efforts to create it, and after our tests, The positioning effect of the sextant is excellent, although there may be some errors, but it is within the acceptable range!" Xie Chun, the leader, said with a warm smile on his face.

Among Li Chunfeng's several disciples, Xie Chun is the oldest one, and he is also highly talented, and he has learned the most from Li Chunfeng, so he is usually the leader.Capital Datang 263

"Sextant? What a miraculous thing!" Wei Heizi's eyes lit up when he heard His Royal Highness Qi Wang proposed it, and he no longer had any doubts in his heart.When he was still in Chang'an, Li Yin asked him to help make two ship models, and these were the Galen Ship and the Fortune Boat, so he has always admired Li Yin's ability.

"His Royal Highness has such a miraculous instrument, can I let the officials take a look first?" Zhao Fu also knew that Li Yin knew a lot, but he was very curious about the sextant in his heart, wanting to see what is so miraculous about this thing?

"It's easy, Xie Chun, you should take it with you, show it to Zhao Biejia, and teach him how to use it by the way!" Li Yin said with a smile.

"Yes!" Upon hearing this, Xie Chun immediately took out a palm-sized sextant from his bosom, then walked over to let Zhao Fu and Wei Gong watch it carefully, and at the same time explained the principle and usage of the sextant.

When Zhao Fu and Wei Gong saw the fan-shaped sextant, they found that the shape was a bit complicated. After hearing the series of professional terms Xie Chun said, they were all dumbfounded because they couldn't understand it at all.Among them, Wei Gong was nothing more than that. He was originally a craftsman, so he knew a little about mathematics, but he was much worse at astronomy and the like.And Zhao Fu was born in the imperial examination, and he also dabbled in arithmetic and astronomy, otherwise he would not have given birth to a daughter as smart as Yifan, but even so, he could only understand [-]% to [-]%. The old face can't hold it anymore.

Seeing Zhao Fu's ashamed look on his face, Li Yin secretly smiled inwardly. In fact, the use of sextant is not difficult, and he can learn it quickly with Zhao Fu's foundation, but he is not familiar with some basic concepts. Understand, such as the concept of latitude and longitude, etc., if he doesn't understand these, he naturally can't understand what Xie Chun is talking about.

Although he only understood [-]% or [-]% of his understanding, Zhao Fu also understood the importance of sextant, but it also reminded him of a problem, so he bowed to Li Yin and said, "His Royal Highness, the sextant The instrument is good, but if you want to "operate", you need the other party to know about astronomy and arithmetic. But take my Dengzhou as an example, there are thousands of registered ship owners, but those who have the basics of using a sextant, It is estimated that it is less than one-thousandth, so is this thing too impractical?"
