"Group A measurement, the angle is 12 degrees 48 minutes!"
"Measurement by Group B, the angle is 15 degrees and 15 minutes!"
"The two sets of measurement points are 60 feet apart."
After the two measurement teams reported the measurement results respectively, the four students took out paper and pen at the same time, squatted on the ground and quickly calculated. Since learning measurement techniques from Su Hao, they were all used to using charcoal pens to write Arabic numerals.
Mathematical operations, as for the trigonometric functions that need to be used in the operations, Su Hao has also specially made a trigonometric function table and distributed it to the students for reference.
The charcoal pens used by the students were very different from the charcoal sticks Su Hao had found before. The pen core was thinner and had a movable wooden pen holder wrapped around it. It looked a little like the mechanical pencils of later generations. For geography,
Surveying requires working in the field, and it is very inconvenient to use brushes and inkstones. This kind of charcoal pen is the best recording tool.
The improvement of measuring instruments was even more obvious. After building the telescope, Su Hao was thinking about using the telescope on the theodolite. With the cooperation of Hao Yizong, Hao Qing and his son, Su Hao successfully transformed the original theodolite.
A special telescope was installed, and a device for adjusting the angle of the telescope was designed so that the angle readings could be accurate to the minute.
With such an instrument, the measurement work is even more powerful. During this period, Su Hao quickly trained several students such as Ma Yu and Jiang Yida, so that they could master the skills of measuring distance, elevation and other indicators. Now
, Su Hao wanted them to show it in front of the recruiters to strengthen their confidence.
"Report to Su Baihu. The calculation results show that the distance between the two poles is 8 feet and 3 feet." Ma Yu was the first to report his calculation results, and then the rest of the students also reported their results one after another, which were completely consistent with Ma Yu's calculations.
same.
Su Hao laughed and said to the young people who were recruiting: "Everyone has seen that we, the students, have just calculated the distance between the two bamboo poles held by the Xiong brothers. Is there any brother who is willing to go over and actually measure it?
?”
Everyone looked at each other. Although everyone was very eager to know whether the measurement results of the students were correct, this was to test whether what the chief said was correct. If the test results were correct, that would be fine; if the test results proved what the chief said
That's wrong. This is a slap in the commander's face. Who dares to do such a thing?
"Haha, don't be cautious, go and take the actual test. If the test results are different from the results calculated by us students, it means that they are not good at learning, and I will punish them." Su Hao said with a smile.
.
After hearing what Su Hao said, a young man named He Benzheng raised his hand to sign up, and then several people also signed up. Su Hao asked Ma Yu to take out a few soft rulers and hand them to them. He Benzheng took the people and ran away
To the Xiong brothers.
"Hey, brother. What were you doing just now?" Xiong Minfan asked He Benzheng who was running over. He was standing about a hundred steps away from the crowd and could not hear what was going on over there.
He Benzheng said: "Just now, Su Baihu asked four students to look at a cylinder. I saw there were pieces of glass on the cylinder. After they looked at it, they talked about some degrees and points.
Then we calculated it and said that there is a difference of 8 feet and 3 feet between the two bamboo poles between you two brothers."
"Eight feet and three feet?" Xiong Minyang, who was standing on the other side, heard it. He squinted at the distance between himself and his brother and said, "This Su Baihu still has a few moments left. I also feel that the distance between me and my brother is
There is a difference of seven to eight feet. However, if you say that you can tell that it is exactly 8 feet and 3 feet, I think it is nonsense? By the way, brothers, you are not sent by Su Baihu to play tricks on others, are you? "
He Benzheng said: "I was still wondering whether you two brothers had received a secret instruction from Su Baihu, and you happened to stand 8 feet and 3 feet away so that Su Baihu could coax us. But I also saw it just now. You
When the two brothers walked to both sides, they didn't even count their steps. They must have walked casually. You two, please stand still and let me measure whether it is exactly 8 feet 3 feet."
Several people who came to measure the distance each had a soft ruler in their hands. They began to measure while muttering. The Xiong brothers stood there and did not dare to move, but their eyes were fixed on everyone's hands.
ruler, waiting for them to reveal the mystery.
"Oh no, it's exactly 8 feet 3 feet!"
"I am the same here, 8 feet 3 feet 2 inches."
"Forget these 2 inches. This bamboo pole is still over 1 inch thick. Which end of the bamboo pole should we count?"
After several people measured the distance, they were all dumbfounded. The distance between the two bamboo poles was exactly the same as what the students had calculated. The only difference was the fraction below a foot. Everyone knew that this was not important.
There was no way to study it carefully. Several people, including the Xiong brothers, couldn't help but turn their heads to look in the direction of the crowd, and estimated how accurate they could be if they were to judge the distance between two bamboo poles from such a long distance.
"He Benzheng, have you finished measuring?"
Someone in the crowd started shouting. Only then did He Benzheng think of his responsibilities. He quickly left the Xiong brothers and ran toward the crowd. He shouted loudly as he ran: "It's done, it's done, 8 feet 3 feet, every cent."
not bad."
When this voice was shouted, people looked at Su Hao and the students in a completely different way. When they heard the students report the distance before, everyone was a little doubtful, but now they heard the people who came to measure the distance.
After telling the exact results, everyone was shocked from the bottom of their hearts. This is a kind of awe for knowledge.
"Why, this is what Mr. Baihu used to measure the distance?" Xiong Minfan, who was carrying a red and white pole, walked to the theodolite that the students had just used, looked at the telescope on it, and asked curiously.
Su Hao walked up to him with a smile and said, "Xiong Minfan, thank you for your hard work. Do you want to have a look at this telescope?"
Xiong Minfan was stupid and bold. When he heard Su Hao speaking to him politely, he nodded and said, "I want to see it, how can I see it?"
Su Hao waved and motioned for him to put his eyes to the eyepiece. Xiong Minfan did the same. He only glanced into the telescope, and then he suddenly raised his head in fear. His movements were so large that he almost hit the tripod.
flipped.
"What's the matter, second brother?" Xiong Min asked looking up.
"Third brother, look at this. It's really strange. There are monsters in it." Xiong Minfan pointed at the telescope and said.
Xiong Min looked up at Su Hao. Seeing that Su Hao had no objection, he also put his eyes on the eyepiece and looked into the distance. After all, he was calmer than his brother, but there was another world in the telescope.
, and it really surprised him.
"Su Baihu, what is this? How can you bring things far away to the villain's eyes?" Xiong Min looked up to Su Hao and asked. He had some disdain for Su Hao before, but now this disdain has disappeared. He himself
He is a smart person and has more admiration for the things smart people do.
Su Hao said: "This thing is called a telescope, and its function is to help us see things in the distance. If we want to do surveying and mapping, we need to be able to accurately identify distant objects. This telescope is specially made for surveying and mapping, so it
There are also scales engraved on the lenses.”
"Su Baihu, will we have the opportunity to use something like this in the future?" Xiong Minyang asked. In just a moment, he had already fallen in love with this thing.
Su Hao smiled and said: "There are plenty of opportunities, but I'm afraid one day you will get tired of this thing."
"I'm afraid it will cost several taels of silver to buy this telescope, right? Can it really be used by us in the future?" He Benzheng also came forward and asked while trying the telescope.
"What are you talking about!" Hao Tong came over at some point. He glared at He Benzheng and said, "This single-tube telescope is worth 50 taels of silver. Please be careful when you use it in the future. It may break."
, I can’t afford the compensation even if I peel off your skin.”
"Oh my god, 50 taels!" Everyone was so scared that they took a few steps back, fearing that they would accidentally touch this expensive thing.
Su Hao had no choice but to step forward and smooth things over: "Don't worry, no matter how expensive the tools are, they are all for people to use. You just need to be careful when using them. If you damage the tools unintentionally, you will not be asked to compensate.
Okay. Let’s all stand, let’s let Mr. Hao Qi preach the military regulations to everyone.”
The recruits left with their tripods and measuring instruments, and the recruits stood up again, facing the platform. Hao Tong strode onto the platform, scanned the audience with a knife-like gaze, and then began to read out the military law:
"Order: In each team, there are to be two justice-in-charge commanders... During the march, anyone who dares to rob and capture more than ten people's property will be beheaded in public. If the leader connives with the sergeants and captures more than ten people, he will be dismissed from his post and sent to the army.
.If there are more than 20 people in the whole army, the leader of the camp and the sergeants will be executed. Those who are new to the army or recruited, do not know the military law, dare to make words to confuse people's hearts, obstruct orders, and cause bad luck, will be executed at a later date.
, and his family will be lost. Those who are on the run from the battle, and those who do not obey the commander-in-chief’s orders, will be beheaded..."
As the word "kill" came out of Hao Tong's mouth one after another, the noise of the recruits below gradually became quieter, and finally reached the level of silence. In the entire barracks area, only Hao Tong's expressionless voice could be heard.
Reading sound.
Su Hao stood behind Hao Tong with his hands behind his back. Listening to these military regulations and looking at the silent recruits below, he couldn't help but sigh:
Discipline is strict enough, and in some places it can even be called harsh. But in reality, how many armies can still enforce it? The discipline of the Ming army is famous for its breakdown. Su Hao even 400 years later
We have all heard of this. Building an army with strict discipline and good fighting skills is something that countless aspiring and famous generals strive for, but how many of them have actually achieved it?
I accidentally became a member of the Ming army, so what should I do in the future? Should I actively devote myself to the construction of the army, or should I just train these scouts as I had agreed with Zhang Hong before?
Retreat from the rapids?
Now that you are here, just work hard, Su Hao said to himself.
