Live Wilderness Adventure

Chapter 648 Vikings and Inuit

In the endless flat snow field, a puff of dry snow was suddenly thrown into the air, and finally fell on the ground.

Having never been to the north in winter, it is difficult to understand what dry snow is.

Grab a pile of snow and squeeze it hard, but it can't be squeezed into a ball at all, like dry flour, the snowflakes are falling down one after another, and a little white dust is floating.

The drone flew up and looked down, only to find that a shallow ditch had been dug out on the flat ice sheet at some point, and Bi Fang was squatting in it, shoveling out the broken ice.

He tied the two knives together at an angle of 90 degrees to form a vertical shovel, and placed another knife in the middle to prevent the two from coming together. He wrapped the third knife with ropes and used it as a shovel. grip.

This is much more convenient than using a chisel.

This is the snow trench, and its main purpose is to defend against the cold wind.

We are still on our way now, and the demand for shelters does not need to be too high, which will only cause a waste of cost.

Bi Fang rested inside for a while, and continued: "There is a lot of snowfall, which is easy to understand. The extremely high frequency of snowfall has led to a large amount of snow on the land. The snow here will not melt, so it will exist to a large extent. It will disappear in the next spring."

"There is no way to keep snow on the sea surface. When snowflakes float into the sea, they will quickly dissolve. As the sea ice gradually expands, the snow on the new sea ice must be thinner than that on the old ice."

"This is a way to judge whether your progress is correct, but it is not very useful in other places. First, it must be in a cold area, and second, it must be near the sea, which will form a seasonal land like an ice sheet. Finally, it will often snow. It’s a way to adapt measures to local conditions.”

[There is no other place to use it except Greenland (cover your face)]

【Learning is useless, learning is useless】

[What if I don’t know where I am? 】

[Catch an honest man who really wants to learn his skills alive! 】

[Lao Fang actually taught it before, a sun, a piece of paper, a pen, a miracle]

[I will calculate the latitude and longitude for you, buddy, have you ever seen the inverse trigonometric function of pen calculation? 】

Many new viewers who have never watched the old video were stunned. Without a calculator, they can still calculate inverse trigonometric functions! ?

Every video has old viewers, and there will inevitably be an influx of new viewers, but it doesn't matter, there will always be enthusiastic fans to help popularize science.

The importance of class representatives is highlighted.

At present, there are already quite a few representatives of professional courses in Bi Fang's live broadcast room who are quite famous. As long as there are inquiries from water friends, they can even give precise answers about the number of episodes and the minutes.

[Can inverse trigonometric functions be calculated in writing? 】

[Theoretically, all mathematical formulas can be calculated in writing. . . 】

[Actually, I want to say that those who understand will naturally understand, and those who do not understand will not understand at all]

[To understand, before becoming an adventurer, Fang Shen was a brilliant mathematician, geographer, biologist, meteorologist, physicist, chemist, historian, naturalist, etc. Are two brushes coming to the North Pole to feed polar bears? 】

[Polar bear (pushes away in distaste): This meat is too thin, we don't eat it]

【Words are very smooth】

【I'm fat enough, will it eat me? 】

The trenches in the snow do not need to be too large. After the depth is more than 60 centimeters, Bi Fang stopped moving. After digging 30 centimeters in the thick snow, the remaining 30 centimeters are on the ice layer. Bi Fang’s hands are sore from digging. It was also dark.

He doesn't know how thick the ice is, but he conservatively estimates it in meters. It is impossible to dig holes for fishing. The deeper the ice, the harder it is. Today, he can only starve.

It was less than seven hours, and it was dark in about six hours. It was true that everyone was stunned. They had never seen such a short day. It seemed that they were going to sleep without doing anything.

Bi Fang walked out of the pit and piled the snow dug out just now on both sides of the trench to make it high.

The nearby snow was compacted hard, but as dry snow, it could not be made into snow bricks at all.

Bi Fang took out all his ropes, pulled them left and right like weaving, and then dripped warm water on the folding points on both sides. The liquid quickly condensed into ice at low temperature, freezing the ropes firmly.

"There are no branches and other objects for the roof. We can use ropes, leaving two lines of three centimeters in the middle, which is enough."

After pulling all the nets, a relatively sparse net appeared in front of him, leaving only space for one person to enter at the end.

Bi Fang piled all the snow on the net, which also formed an airtight roof.

Entering through the gap, Bi Fang breathed out the hot air to block the cold wind, and he felt his body warm up quickly.

"Snow houses and igloos can trap heat, but they are different from houses. They change minus forty degrees to minus ten or five degrees. At this temperature, the ice and snow will not melt, but we can clearly feel the warmth. .”

"Five degrees below zero is not considered cold at all, it is the temperature of normal human activities."

Bi Fang huddled in a corner, chatting with the audience, and it was too early for bedtime, so he told the previous story of the Vikings again.

The audience is also very curious, what is the ending of the Vikings?

"The Vikings stayed in Greenland for a long time, from the 10th century to the 14th century. During that time, Greenland's climate was relatively mild, and it could be planted and grazing. The settled Vikings could rely on reserves for the winter."

"Later, the climate changed, production could not be maintained, and the Vikings couldn't make a living like the Inuit, so they couldn't survive."

"It happened to be the Little Ice Age at that time, and the sea route from Iceland to Greenland was blocked by ice floes. Greenland has no timber for shipbuilding, so even if the sea route is clear, I am afraid it will not be possible to travel."

"There was a wedding in Hvalsey Church in 1408, which is the last record of the Norwegians in Greenland. Since then, the communication between Greenland and Europe has been interrupted, and no news has come. It can be regarded as the Vikings in Greenland. 'Extinction' on

"Arguably, it was nature playing a joke on Eric the redhead, who just happened to be in Greenland for the best date."

"When the Vikings first arrived in Greenland during the brief Medieval Warm Period, they could be said to have been deceived by nature."

"Since ancient times, Greenland, like other polar regions, has experienced many climate changes, affecting the growth of local flora and fauna, and the survival of aboriginal people. During this period, in addition to the Vikings, there were also Inuit people who settled in Greenland ; the former went extinct and the latter successfully overcame the challenges of the Little Ice Age."

People have been to Greenland in an endless stream, but the only ones who have survived for a long time are the Vikings and Inuit.

After the Ice Age came, the Vikings declared their defeat, but the Inuit continued to prosper.

This is a race in ice and snow.

Bi Fang used the example of the Vikings to warn himself of the cruelty of nature, but he wanted to pick up the experience of the Inuit to arm himself.

"The former lesson is what we have to avoid, and the latter is the key to my success in this challenge."

The hottest place in the world is not in the African desert, but in Death Valley in California, USA.

On July 10, 1913, the desert valley in Death Valley reached 56.7 degrees, which is the current Guinness World Record holder.
