Chapter 2000： Unlucky Dürer

In the absence of modern photoelectric measurement equipment, in ancient times, surveying and mapping was a very troublesome and complicated thing, not only required a lot of manual measurement, but also needed to calculate trigonometric functions according to angle.

Therefore, surveying and mapping in this era not only requires a lot of manual measurement, but also requires a lot of calculations. The main calculation is to calculate the distance and height through the Pythagorean theorem by measuring the shadow length of the wooden pole and the angle of sunlight under the principle of geometric proportionality. To this end, Marin also let people compile a trigonometric function comparison table, which lists the trigonometric function values ​​at different angles in detail. In this way, when surveying and calculating, it does not need to be so troublesome, just look up the table.

However, this is a relatively short distance survey. If you encounter a long distance, Marin directly gives the latitude and longitude measurement method, as long as the sextant is used to measure the latitude and longitude of the two places in detail. Then, based on the numerical values ​​of the equatorial circumference of 40078 kilometers and the meridian of 40009 kilometers, and then based on the difference in latitude and longitude, using simple geometric calculations, and then looking up the table, you can get the approximate distance between the two places. Although there are errors, it is within the tolerance range.

In addition, in addition to the need for a large number of surveyors in the military, the civilian population also needs a large number of surveyors. For example, when constructing a project, it must be applied to a large number of surveying and mapping. Therefore, the demand for surveying and mapping personnel in Beihai is very large.

Therefore, in order to train surveying and mapping personnel, Marin simply established the School of Geology at Aurich University to train comprehensive geological talents. As for the training of surveying and mapping personnel, it was handed over to the surveying and mapping major of the College of Geology. However, the surveying and mapping major of the School of Geology has two training programs. One is to recruit college students, specializing in geological research and civil map surveying and mapping. Another training plan is to help the military train committee students. All soldiers with good geometric foundation and good sense of direction can be sent to the College of Geology for training. After the training, the surveying and mapping soldiers will be paid according to the treatment of grassroots officers. Living conditions and benefits are much stronger than ordinary soldiers

Moreover, these surveyors did not have to go home to farm after they retired. Because of their skill, they will be assigned to the land management departments in various places, and they will be responsible for land measurement and verification. Anyway, they also have a good iron rice bowl.

Because it is necessary to make sand tables that restore topography and landforms, those surveying and mapping soldiers need to learn not only geometric calculation methods but also painting methods. The most basic is sketching. Because, as surveyors and mapping personnel, when drawing maps and topographic maps in other countries, they need to use sketching methods to quickly draw the characteristics of the local mountains and terrains, so as to provide reference for officers to make sand tables. After all, if you want to draw terrain features on a site in another country, you need to make a quick decision. If it is delayed for a long time, it is easy to be discovered. At the same time, because there are too many mountains and rivers, it is easy to make mistakes if you draw slowly like oil painting.

Therefore, every surveying and mapping soldier is not only a master of geometry, but also needs to be good at sketching. In this era, it is definitely a talent.

The great painter Dürer, who was solicited by Marin, happened to be the king of sketching. Therefore, the hapless painter Dürer, while busy working on science for Da Vinci, also needs to go to the newly established College of Geology as a sketch teacher to teach students how to draw sketches.

It's also hard work to say. Dürer was a noble painter and a guest of many nobles. He is not only proficient in painting, but also has a deep research on carving, alchemy, mathematics, mechanics, literature, anatomy and architecture, etc. Geometry also has a good attainment

Malin had originally arranged for him to study with Leonardo, hoping that he could become Leonardo's second. After all, this product was originally a low-end version of Da Vinci, with comprehensive capabilities and versatility. Moreover, he is much younger than Da Vinci and has great potential.

At present, this guy is leading a research group to study single-cylinder diesel engines. However, Marin felt that even if the single-cylinder diesel engine was well researched, there was not enough diesel. Therefore, it is better to have a steam engine. As it happens, this guy is also proficient in geometry and is very suitable as a geometry teacher in surveying and mapping. Then, Dürer had a cup and he was appointed by Marin as a geometry teacher and sketch teacher in the surveying and mapping major of the College of Geology, and is currently the only teacher in the surveying and mapping major of the College of Geology

Dürer was not happy, after all, he is now with the idol Da Vinci, although he can learn a lot. But Ma Linneng used to give him only two options. First, he took the initiative to teach at the College of Geology; secondly, he was taken away by fainting and was forced to teach at the College of Geology.

Facing the unreasonable demands, what can Dure say about the School of Geology is also in Aurich, he can still meet with idols and ask for advice.

Da Vinci was also dissatisfied with losing the coolie of Dürer and being the best assistant. After all, Dürer was a very smart person and a rare genius in this era who could match his brain waves. There are many things for Dürer to be his assistant. As long as he starts his head, Dürer can understand his meaning and get it done. After all, Dürer claims to be the German Leonardo, very similar to Leonardo. Both are painters, and their hobbies are similar. They are the same series. The only difference is that Da Vinci's skill is deeper, and Dürer is much worse, but it is a low-end version of Da Vinci.

But because the two are too similar, Da Vinci also attaches great importance to Dürer and wants to teach his life what he learned and let him inherit his mantle.

However, when Marin wanted to leave Dürer, Leonardo was helpless. Others didn't know, but he knew Marin's hooliganism, and he stunned and took away if he didn't agree. In the beginning, he was kidnapped from Milan to East Friesland. Therefore, he knew very well that even if he wanted to stop it, he could not stop the determination of Marin, the "head", to take away Dürer.

On that day, Dürer held Da Vinci's hand tightly and choked silently

"Teacher, take care of yourself" Du Lei was full of tears, reluctant.

"Tuer alas" Da Vinci didn't say anything, because he knew that he could not change what the Ma Da rogue decided.

Marin on the side couldn't see it, dissatisfied and said:

"It's not impossible to meet again, all in a city, and I'm worried that I won't see you"

Marin did not mention the same university, because the College of Geology is not placed on the main campus of Aurich University, but on the edge of the city. As a result, there was no more space available on the main campus. Then, the major of surveying and mapping is a confidential course, which requires many confidential instruments such as telescopes and sextants. Therefore, it is not suitable to appear in the open main campus. Therefore, the School of Geology was placed on the edge of the city, next to a barracks, and security was very strict.

"I wish I could always follow the teacher and accept the teachings of his old man," said Dürer very artistically.

Marin heard his teeth sore and waved impatiently:

"Okay, you don't have to be sore. So, you can go to the School of Geology during the day to teach, and you can come back to Ada as an assistant after class, as long as you are not afraid of the back and forth.

"I'm not afraid of suffering." Before Marin finished, Dürer expressed his position.

For a scientific maniac, being able to learn and engage in scientific research is the happiest thing. Even, in order to study with Leonardo, Dürer lived in university dorms for a long time and didn't go home very much.

Of course, it is a fact that Dürer and his wife Agnes have a bad relationship. The marriage between Dürer and his wife Agnes was decided by his father. The wife came from another family of artisan owners. The father-in-law and father were old friends. But the relationship between the couple is very weak, not good or bad.

In history, Dürer did not return home for a long time, and his wife did not leave the wall. Therefore, the couple had no children for life and no children. Even, Agnes does not like what art Dürer does, nor does he like Dürer's artist friends. Because, Agnès, the daughter of the owner of the artisan, pays more attention to money and wealth, and Dürer's thought is not on the same channel.

But in this time and space, Dürer was forcibly recruited by Marin, and Agnes followed Dürer to the North Sea. Because of the importance of Dürer, after Dürer became Leonardo's assistant, Marin directly gave a title of noble to the jazz, which made Dürer's very utilitarian wife, Agnes, very important. Then, the relationship between husband and wife improved a lot, and even had children. The actual situation is that Agnes took the initiative to reverse the relatively cold husband Dürer

However, Dürer is an art maniac and technical house after all ~ www.novelhall.com ~ So, even if he gave birth to a daughter with his wife, Dürer still values ​​the opportunity of learning from Da Vinci more than family.

Marin squeezed him so much that he was as happy as he was. Of course, he mainly likes to follow Da Vinci to learn, rather than like to be a teacher of the College of Geology. But if he didn't go to the School of Geology, someone would come to knock him out and take him to the School of Geology forcibly. Therefore, even if he is not satisfied, he can only do so.

And Marin asked him to go to Da Vinci to work overtime after staying in the School of Geology. He did n’t have any dissatisfaction. It was a fanatical technical house.

"It's such a bad boy" Da Vinci shook his head, sympathizing with Dürer's experience. However, he is not so in the North Sea country, Da Vinci alone is almost 10 people in use. He is a full professor of science at Aurich University, majoring in mechanics, physics, and chemistry. He is leading students all by himself. Although the first batch of graduates have already graduated, they are still following his experience and can not pick the beam. Therefore, he is the most tired person. Dürer just started to follow his old path. In short, their mentor and apprentice, in this life can be regarded as selling his life to Marin. Fortunately, the things they do are all sciences they love very much. Although Marin desperately squeezed the two of them, the treatment he gave was not low. Moreover, they also learned a lot of scientific knowledge from Marin, which is also a huge benefit. Otherwise, their mentors and apprentices are arrogant and arrogant geniuses, where is willing to be so crushed by Marin
