Rise of Rurik

　　Lurik’s house stored a lot of currency, and the people of the tribe knew that the leader’s house must have a big treasure chest full of wealth.

　　 No one tried to take the treasure as their own. Maybe someone had a bad idea, they just gave up when they thought of the terrible result.

　　Because the core members of the Rus tribe are the current scale of a family after many generations of reproduction. Robbing the belongings of clan members is a serious crime. The thief will be executed unceremoniously, and the thief’s property will be inherited by the victim.

　　 What's more, the people who live near Rurik's house are those whom my father trusts most. They all have a close blood relationship with his father.

The large amount of boring time of the child gave Rurik time to play with a large number of silver and copper coins. He heard about his mother with a strong purpose, and basically figured out the price situation within the tribe, and then calculated those allies’ Something.

　　In the Baltic rim, and even throughout Western Europe, various currencies minted by Eastern Rome are the most mainstream currency in circulation.

　　 But the sources of these currencies can be described as diverse, and there are even copper coins minted from the late Western Rome are still in circulation. In the end, an excellent businessman must understand the exchange ratio between different currencies caused by the difference in fineness.

　　The people of Scandinavia prefer the silver coins and silver coins minted on a large scale in the seventh century of Eastern Rome. Generally speaking, they can get a lot of silver coins.

　　 Those silver coins that are close to the current era are generally of good quality, but the silver content is not complimented.

　　 After the discovery of the New World, hundreds of years before the massive influx of South American silver into the world market, not much silver was circulating as currency.

　　Eastern Rome had to process a large number of silver and gold coins, especially silver coins, which weighed only a little over four grams.

Six silver coins are roughly estimated as one ounce (the ounce setting in the ninth century). It is generally accepted by the merchants of the Viking tribe. After all, they have not yet researched the technology of coinage, and even the level of the Frankish Empire in this regard. Very bad.

　　 Although it was a powerful enemy, the currency of East Rome circulated at the same time in the East and the West, and the distant Baltic Sea was also its circulation area. The Romans did not expect this at all.

　　A very good silver coin can be exchanged for other currencies of various colors and animal skins from different species.

　　 Need an object to measure the value of Eastern Roman "good-quality" silver coins. There is a customary exchange ratio between the Rus tribe and its southern allies, that is, one stika of shaved sheepskin corresponds to one "good-quality" silver coin.

　　 Of course, a "good-quality" gold coin corresponds to exactly ten "good-quality" silver coins. Gold coins are scarce, and they are rarely used in trade.

　　When it comes to important goods, silver coins are used in large quantities. On weekdays, transactions of the Ross tribe can be basically achieved through Roman copper coins.

　　The exchange ratio between copper coins and silver coins is also quite amazing.

　　Any number system needs to be used to solve actual mathematical problems. Lurik uses a large number of symbols commonly used in modern mathematics, which naturally attracts Veria's attention.

　　 She asked about the meaning of some "Roman vocabulary" marked on the wooden board, but Rurik didn't think much about it. In other words, it means angle.

　　 There are vocabulary words with similar meanings in Old Norse, and Rurik’s brief explanation by Villia was quickly understood.

　　 Maybe if I give a good lecture, she will fully understand?

　　Lurik enters the state, but he miscalculates the fact that Veria seems to be able to quickly understand that she is still a person with extremely limited knowledge.

　　What is the existence of the inclination of the earth, the real reason for the cold in Roseburg, and the change in the direct angle of the sun, Lurik is like a teacher who taught him a full seventy-year-old student.

　　Villa is trying to sit quietly, she is like quickly understanding the child's words, but unfortunately she can understand many Gnostic vocabulary, but they can't understand them when they are put together.

She at least understood that the child Rurik said a lot of things, and quickly cut a charcoal block with a knife to make gestures. What the child did was trying to convince herself that the original face of the world was a revolving one. Big ball.

　　 Because of the rotation, day and night change.

　　 Because of the tilt and rotation, there are four seasons of the year.

　　 A speaker, after finishing a report, is often happy that he has done it well. Rurik seemed very interested. Since his birth, he has not done any scientific popularization to another person, just because he has never found a friend.

　　 "Grandma, do you understand now? We don't have to fly into the sky to see the whole world with our own eyes. We only need to make some measurements on the ground to describe the whole world."

　　Villa shook his head deeply: "My child, I'm too old. I can't understand what you said. Even if I understand it, what's the point? My life will end soon."

　　 Her words add another color of sadness.

Honestly speaking, Rurik really regrets the elderly Vilia. If she did not live in such a barren era, for example, a thousand years later, even though she was a female generation, Vilia could also become a female in Sweden. scholar.

　　 "Grandma, I really hope you can continue to live, at least... at least to be a hundred years old."

"Don't be silly, boy. I have served Odin all my life, because of your existence, I think I have been recognized. That is my destiny, and I will become another Valkyrie. Child, you are happy. Odin I have given you a lot of knowledge. These must be Valhalla's truths, which are difficult for mortals to understand."

　　 "No! Grandma, all the knowledge I know can be understood by mortals."

　　 "Oh? You are a messenger, will you impart knowledge to our tribe? After all, that is Valhalla's knowledge."

"I will, and I think Odin will definitely support it." Rurik thought for a while and swore very boldly: "I have a dream to let the children of the tribe learn my knowledge. Well, Val Hala’s knowledge. Don’t worry. Odin did not prohibit us from spreading knowledge. Maybe everything is their plan. They need to recruit the warriors to learn wisdom in advance."

　　 The great development of human civilization begins with the emancipation of the mind. The bound thoughts suddenly become active, and mankind quickly enters the industrial civilization.

　　In just two hundred years after the industry’s first sound, mankind has created 97% of the wealth of 10,000 years of human civilization. Mankind has even forgotten that half-starvation is the normal state of life for a long time.

　　 In the ninth century AD, the number one driving force that drove the Vikings to leave their homeland to engage in barbarism was hunger.

　　Villa still felt that Rurik’s words made sense, and she asked, "What if those kids are unwilling to obey you?"

"I will give orders, because I am the leader! I will force the children to learn! Only the most knowledgeable and good at fighting can be my cronies. I will appoint them a greater job and give them more wealth. .My grandma, believe me, if learning knowledge can bring greater wealth, no child will be willing to continue to be a stupid person. Therefore, I will also order all girls to learn knowledge, I believe there is only a smart mother in this case Smarter kids in the Education Department."

　　Lurik is surprisingly speaking again, and the possibility he presents now is something that Veria has never thought of.

　　 Not to mention whether it is feasible for boys to receive education, he actually thinks that education cannot be differentiated between men and women.

　　Villa can resonate very well, because the priests of the tribe are basically monopolized by women. As a priest, you must learn a lot, especially to accurately recite those prayers.

　　 Obviously, the meaning of Lurik is not to let all tribal girls be priests, but to learn other things, such as making the children believe that the world is a ball.

Veria's wrinkled old face gradually showed a smile, and then she giggled: "Son, I see the hope of the tribe, my life has no regrets. Maybe the world is a ball, now continue your calculations! I Need an answer."

"Ok!"

　　Actually, by now, Rurik has basically determined that the location of Roseburg is just at the extreme position of the Arctic Circle.

Rurik is a rigorous person. He feels that he must obtain an accurate result through the measurement data~www.readwn.com~The error of the Julian calendar is already very serious. Fortunately, based on the daily experience provided by Veria, Rurik I very much believe that the real winter solstice has been postponed to December 28, and will even be postponed to the 29th in a few decades.

　　Through Veria’s explanation, Rurik understood that the priest can accurately predict the correct day of Hanukkah is by no means a pinch, and everything has to start with the Roman men in black who Veria met when he was young.

　　 After all, in the concept of most people in this space-time, the world is eternal, and the sun, moon and stars are also eternal.

The makers of the calendar believed this. They were very annoyed that there was always a flaw in the calendar that they made, which prevented it from becoming eternal. The priests in Rome determined the accuracy of the calendar through astronomical observations, and Vella not only knew it thirty years ago The Julian calendar also knows the error.

　　 She has never thought that there are still errors in this calendar. Fortunately, the errors generated in 30 years are very small, which makes her every prediction extremely successful!

　　 Bringing the true winter solstice into the calculation, Rurik quickly calculated the true direct sun angle today, which is indeed very different from the measured data just now.

　　Using the new data and then importing the formula, the conclusion reached is that the north latitude is slightly more than 66°, which is nearly 3° larger than the previous data.

　　 66°N is very interesting, because the Arctic Circle is delimited by it. This data is also very consistent with Veria's experience, only in such a position, and only on the winter solstice day the sun will not rise.

　　Lurik showed his answer to Veria, another lengthy explanation.

　　 He didn't know if the wisest priest understood what he said, at least there was a kind smile on the wrinkled face of the priest.

　　 She should understand a lot.
