The weapon tycoon who traveled to Daqin

Shang Wen does not care about the exercise. What he wants to do is to use astronomical knowledge to popularize the latitude and longitude. This is where the urgent needs have been reached. Others sell you a blockbuster land. And you can't measure acceptance now. Then, you are before.

The legal provisions will be regarded as a piece of waste paper. Such a serious test of the authority of the law.

For the authority of this law, Shang Wen has to learn. Those Shang Wen himself is unwilling to learn astronomical knowledge, because it contains a lot of mathematical knowledge. If you add unclear explanation, it is likely to cause this door.

Knowledge was terminated.

To this end, Shang Wen first copied a lot of knowledge. With a lot of knowledge, it was not enough, and a large number of instruments were needed. Especially the six -point meter. This is also an important measurement tool for the naval navigation in the future.

Yiyi has become a mainstream navigation instrument. It still uses it so far.

These two instruments Shang Wen thinks that they are necessary to make them. Only in this way can they explain to them objectively. Otherwise, they cannot abstract understanding. Knowledge is still too esoteric.

A more important instrument in the instrument is to reflect the telescope. Fortunately, the glass. Mirror, etc. are now developed. Otherwise, because the reflective material. Shang Wen has a headache. The reflecting telescope also needs to make a series of production.

Observer can see the horizon through a mirror at the same time. The angle between them can be measured by marking the quadrant marked with a scale, and the range of the angle can reach 90 °.

The height has doubled, becoming an ideal instrument for latitudes. This is an eight -point meter.

Subsequently, the improvement of the eight -point meter as the mode, expanding the measurement range to 120 °. This is the six -point meter. It is composed of a triangular shelf. On the one hand, it is a 120 ° arc.

Poinage. Pet reflected telescope reflects the two -day body that needs to be measured together. People can easily measure the angle and calculate the latitude of the ship.

This is a relatively simplified measurement method later. But the principle still does not make it clear. Shang Wen feels that it should find a more intuitive method to explain. The method is to set up a pole on the ground to constantly draw its shadow. When the shadow is the shortest, the shortest is the shortest time.

, Record the direction of the shadow at this time. This is the direction of the north. Measure the length of the shadow and pole at this time, use the trigonic function to calculate the suck angle of the sun, and then consider the dates of the day distance (autumn) and summer (winter) to the date.

Use the triangle interpolation to calculate the direct latitude of the sun on the day of the sun. After additional, you can get the local latitude value.

But this requires a known quantity. But not only these. Shang Wen hopes that his explanation can make them understand. In fact, the reason why these things can appear are due to the artillery science of Qin Kingdom.

Geometric knowledge. Especially triangular mathematics functions. They have experience, but they cannot transform. The measurement of engineering has a good transformation. But their level of measurement cognition has not risen to a height. This height allows Shang Wen himself to himself himself himself

Come to help it complete.

Just when Shang Wen was preparing to prepare a specific measurement method. Two Qin Army officers came to come to the door. They were the officers and men of the first division and seven regiments. One was the chief of the colonel.

The focus is very headache.

The reason is the military merit. Qin Kingdom used a new reward method. But there is a big difference in the standards of rewards. The difference is that it is no longer calculated by the head.

The staff department set up a special department, the war history department. They are responsible for collecting the battle before and after the battle, and then determine the efficacy of some people according to the list provided by the battlefield commander. This can provide a large number of textbooks for military schools. At the same time

Can summarize some of the shortcomings. It can be said that compare systems.

And military merit is often determined according to the history of the war. Because what happened on the battlefield. Everyone participated in it, and it is impossible

It is impossible to determine the important reasons for the issue of military contributions. Writing the history of war history itself is an officer. He often writes according to his preferences.

"Chief, I think my nine captains should have the gold medal. Not a silver medal. Because of his orally, I guess, no, speculation, he should kill a big man." This name

Colonel was excited.

"Oh. Can you show some vouchers?" Shang Wen asked.

"The battle has ended for a long time. At that time, the other party had others, and it was impossible to show the vouchers. Even those blood stains had no shadow." Lieutenant Lieutenant said excitedly. Colonel was still restrained.

"This problem is difficult to do. However, I will blame the Staff Department to investigate this matter. But I need you to provide detailed locations, time, and related characters. It is best to have their troops, position. I need to find these."

Shang Wen said patiently.

"No problem, the chief." Lieutenant Jiu said very much.

"Very good, you go back and submit a report. I will transfer it to the staff department. Now the Gold Medal has not been issued. The main reason is that some front -line troops have not withdrawn the place.

One point. If the replenishment is more troublesome. However, if you don't care, I will give you it. "Shang Wen said.

"Thank you Chiefs." Lieutenant Jiu stood up and raised his hands.

"Don't thank you. By the way. What is the name of Lieutenant Nine? What is your position?" Shang Wen asked in detail.

"My name is Jiu Ban Soul." Lieutenant Nine answered.

"He is the god gunner of our group. He is very courageous. A person crosses the front to shoot the opponent's officer." Shang Wen nodded. He expressed his supplement to the leader of the team.

"Do you like the barracks?" Shang Wen then asked.

"Of course." Lieutenant Nine replied.

"How about joining the Marine Corps?" Shang Wen said.

"I mean, this is a brand new military. It is estimated that you have also seen it. The probability of a large -scale war explosion is already very low. The next war is mainly small -scale warfare. Therefore, this new military is dealing with this to deal with this.

Situation. They need a reliable fire support. For example, shoot the opponent's commander. Do you be interested in joining? "Shang Wen asked.

"This." Lieutenant Jiu looked at his head.

"Chief, I need to think about it." Lieutenant Nine answered.

"Well." Shang Wen replied.
