In Deng Yuhan's small laboratory, Luo Yagu, Xue Fengzuo and others saw the astronomical telescope made by Zuozhuang.
"Oh my God, this is definitely the most accurate telescope I have ever seen."
Luo Yagu was full of praise for this astronomical telescope after operating it in the field.
Xue Fengzuo looked frightened.
He has just started studying with Luo Yagu and has not mastered much knowledge yet. I had only heard from Luo Yagu before that you could use tools to observe the starry sky in Europa, but I had never seen it in person.
Today, Xue Fengzuo is in the process of changing his thoughts and knowledge. His understanding of astronomy still retains the traditional Chinese imagination.
For example, the stars are the places where gods live, which are far away and cannot be desecrated.
Now, he has seen the moon through an astronomical telescope, and he has also seen many planets.
There is no Chang'e on the moon, and there is no moon palace, and there is no Wu Gang who exposes his tendons and cuts trees all day long to seduce Chang'e.
This fact made Xue Fengzuo quite devastated. But at the same time, it further stimulated his interest in Western learning.
Over there, Luo Yagu, Deng Yuhan and Zuo Mengeng had already discussed the issue of this astronomical telescope.
Speaking of this, Deng Yuhan was full of praise for Xu Ruolin.
"Zuo's fiancée is the best female mathematician I have ever seen in the world. Without her precise calculations, such an excellent telescope would not have been possible."
It was not until Xu Ruolin came to Linqing that Zuo Mengeng realized that the original mathematical knowledge here was not enough to support the manufacture of larger astronomical telescopes.
It’s not that it’s not technically feasible, it’s that it’s not computationally efficient.
For example, the numerical value of the concave-convex ratio of the lens cannot be calculated using traditional algorithms.
The measuring tools used by craftsmen are also unable to measure.
With the help of Xu Ruolin and the use of logarithmic algorithms, the standard proportions of astronomical telescopes were obtained.
Based on Xu Ruolin's instructions, a logarithmic ruler was created.
The emergence of logarithmic feet, in turn, helped the manufacture of heavy artillery.
Regarding these things, Zuo Mengeng could only lament that industry and science are indeed an extremely complex and closely related system. Any little bit of progress has a huge impact.
What Xu Ruolin is currently studying is making complex logarithmic rulers.
The complex logarithmic ruler is of great help in the calculation of square roots and powers. Once successful, Zuozhuang will see a huge improvement in the manufacturing of machine tools.
Before the invention of computers, the logarithmic ruler's influence on human society lasted for more than three hundred years.
Although Zuo Mengeng was not very proficient in mathematics, he knew that this matter was great, so he fully supported Xu Ruolin in her research.
He also said something to Xu Ruolin using his limited mathematical knowledge.
"Logarithms are the inverse operations of exponents."
This is a principle that all junior high school students will know in later generations, but in this era, the significance is undoubtedly huge.
Xu Ruolin didn't believe it at first, but after doing the calculations herself, she almost broke Zuo Mengeng's head open.
I just want to see how someone with such poor math skills could discover this mystery.
Just because of Zuo Mengeng's words, Zuozhuang's mathematics level suddenly improved by nearly a hundred years.
The happiest person among them was Xu Ruolin.
No one in the Xu family except Xu Guangqi supported what she did.
Everyone thinks that since she is a girl, she should stay close to home and learn how to be a knitting girl. When she is old enough to get married, she should be able to support her husband and raise children.
Yes, even though the Xu family is a Christian family, except for Xu Guangqi, the open spirit of others is far from enough.
After arriving at Zuozhuang, Xu Ruolin had no restrictions and did everything she was good at and liked.
People here are not prejudiced because she is a woman. On the contrary, they are very convinced of her abilities.
Perhaps this was because she was Zuo Mengeng's fiancée, and people regarded her as their future mistress, but the feeling that she was useful made Xu Ruolin happy to be alone.
In the next few days, Xue Fengzuo participated in academic discussions with Xu Ruolin, Deng Yuhan, Luo Yagu, Bi Maokang and others. Here he also met celebrities such as Hou Xun, Li Banghua, Geng Ruqi and others.
On the one hand, he was baptized academically, and on the other hand, he was influenced by famous ministers and scholars. Xue Fengzuo decided to stay in Zuozhuang and join Xu Ruolin's mathematical research.
Although Zuo Mengeng didn't know how powerful he was, he felt that he was a talent. Since you are willing to stay, it must be what you want.
Not only did Xue Fengzuo stay, he also wrote two letters and asked someone to send them to Zhili.
He knew that there were two teachers there who were in trouble.
They should take a look at Lai Qing and see this different place.
With the arrival of Hou Xun, the court also came to deal with Zuo Mengeng.
Although the entire New Army was furious about the punishment of being demoted two levels, Zuo Mengeng didn't care.
This penalty is equivalent to no penalty.
Even if Chongzhen deprived him of his status as Dongchang Associate General, wouldn't the entire New Army still listen to him?
Zuo Gui brought an old man to visit him.
"Lu Jingyuan of Changfeng Escort Bureau has met General Zuo."
Zuo Mengeng heard Zuo Fu and Zuo Gui mention Lu Jingyuan's matter. Lu Jingyuan was a big help during the trip to Dongping.
"Why does Mr. Lu, the bodyguard, have time to come to my place?"
His kindness made Lu Jingyuan feel at ease, and he hesitantly told the matter.
"The villain is reckless and despicable. I dare not insult General Zuo's sight and hearing. But where morality lies, the villain has no choice but to be rude. General Zuo, please save King Li Tian."
After hearing what Lu Jingyuan said, Zuo Mengeng knew that the war between Li Qingshan and Guo Yunbiao in Yanzhou Prefecture had changed.
Although Li Qingshan has a high reputation and is quite popular. However, the people he could gather were mostly idle people. Even if there are people with outstanding military strength among them, they will not be able to exert much power if they are scattered.
On the contrary, Guo Yunbiao was running the headquarters of the White Lotus Sect. Not only are the troops strong and well organized, they are also capable of fighting even against the official army.
The two sides have been fighting since the beginning of the year, and until now, Li Qingshan's defeat has become apparent.
According to Lu Jingyuan, Li Qingshan currently has more than 500 brothers who are surrounded by Guo Yunbiao in the village of Liangshan.
Guo Yunbiao hated Li Qingshan so much that he left other good places alone and must destroy Li Qingshan first. Therefore, Li Qingshan was besieged and the attack continued for more than a month.
If it weren't for the poor military quality of the White Lotus Sect, Li Qingshan would have died long ago.
After the White Lotus Sect uprising in various places, Lu Jingyuan knew that Li Qingshan would be retaliated by Guo Yunbiao, so he sent his subordinates to Yanzhou Mansion many times to inquire.
Knowing that Li Qingshan was in danger, Lu Jingyuan was furious, but there was nothing he could do.
He is just a dart driver. Although he is famous in the world, he is not useful to people in the world when it comes to fighting.
After thinking about it, he thought of Zuo Fu and Zuo Gui.
Nowadays, no one in Linqing knows about the great things Zuo Menggen has done. The New Army brigade also trains outside the city every day, showing extraordinary power.
To save Li Qingshan, we can only rely on Zuo Mengeng's troops.
Zuo Fu was so elusive that Lu Jingyuan could not be found. But Zuo Gui has always been in charge of the activities of three religions and nine schools in the world, and he happened to be opposite Lu Jingyuan.
Zuo Gui had a good impression of the chief escort, and he also accepted his initial feelings.
It happened that Zuo Mengeng had just been reprimanded by the emperor and was about to send out troops again, so he brought Lu Jingyuan to Zuo Mengeng.
The New Army has actually been discussing the issue of sending troops these days.
There are only two directions, one is Yanzhou Prefecture and the other is Jinan Prefecture.
As for Qingzhou Prefecture...
Zuo Mengeng decided not to care and let King Heng suffer more.
But no matter what, the ultimate goal is to force the White Lotus Sect rebels into the Yimeng Mountains.
Since Lu Jingyuan came to ask for help, Zuo Menggeng decided directly to attack Yanzhou Prefecture first to save Li Qingshan.
Li Qingshan has a huge reputation in the Dongping Lake area. With his support, the New Army will get a piece of territory in vain.
Such a good deal, when Zuo Menggeng mentioned it, everyone was in favor.
However, when it comes to beating Guo Yunbiao, there is another problem that cannot be ignored.
"The water network in Dongping is dense, and the White Lotus Sect's lair is in the water. However, our army does not have much experience in water warfare, so we need to pay attention."
Ryu Il-won gave full play to his duties as chief of staff.
Deputy Chief of Staff Zuo Yong also mentioned a difficult problem.
"For water operations, heavy artillery cannot be used. Zuoying artillery also requires a strong enough ship."
Both canals and Dongping Lake belong to inland water systems.
The size of the ships that can sail here can be imagined. Not to mention heavy artillery, even Zuoying artillery may not be able to withstand it.
Zuo Mengeng was not intimidated by the difficulties, but said: "No matter what, water warfare is one of the issues we have to face. Even if it is not important now, we will have to experience it when we go to Jiangnan and the sea in the future. I think it is not as good as Taking advantage of the fact that the White Lotus Sect is not strong enough, it would be better to train our army’s water warfare capabilities first.”
When everyone thought about it, it was indeed the case, and the hesitation in facing difficulties was eliminated.
The next step is for the major families to collect ships and then select suitable ones to practice first. In particular, artillerymen must be adapted to master the art of firing artillery in water battles.
At the same time, the intelligence department and scouts were also sent out and began to collect intelligence in the Dongping area as a reference for the upcoming expedition.
After nearly two months of rest, the new army is about to go out again.
