It's Okay To Be Smart (1 year ago)
Regarding use of the word "Eskimo" in this video: We are now aware, thanks to many polite comments from our audience, that this is viewed as a derogatory term among many native peoples of Canada, as well as in some Arctic regions. Several of our references centered on Alaskan natives, among whom this term is more commonly accepted. Additionally, we used the term in reference to native languages, which are more commonly referred to as Eskimo or Eskimo-Inuit, and not the people, but we should have been more clear and sought out another term. We apologize to those we offended, and have learned a lot. We'll do better in the future, as we always aim to do.

+Zaghir It doesn't have anything to do with the US or the Democrats, it's seen as an offensive term in Canada.

Is that why eskimos hunt seals as a hostage for their igloos? For heat source?

What bunk. This video is just random associations. An igloo keeps you warm for these reasons: 1. It blocks the wind 2. The sleeping platform should be above the level of the door opening, heat rises so the dome captures body heat and warm breath. [So good igloos are usually dug down a couple of feet.] 3. The temperature in an igloo with a person or a candle will rise to the melting temperature of snow 0 degrees C at which point any additional heat begins to melt the interior walls. My experience is they drip. [block up part of the door, but make sure there's a small opening size of your fist high on the dome on the opposite side. You could suffocate in an igloo. And have a sheet of plastic to put over you and your sleeping bag. 90 percent of the drips in an igloo seem aimed at your forehead or an eye.) 4. Air in the snow? Okay.good point. A snow igloo is probably warmer than a solid ice one (I don't have any experience with an ice igloo). So inside an igloo no matter how cold it gets outside will be about 0 C, which is better than high winds and -50C . If you'd like to make an igloo, and I think you should, you don't need anything fancy. I made one with a machete. Watch Nanook of the North a few times to see how he did it and then find some deep snow you can cut into blocks. It'll take all day. Wear snow pants. Catenary? I don't think so. I'll watch Nanook again.

Not a catenary. Simple round arch. Here's a couple of guys who know something about igloos https://youtu.be/0W05zqydFsE This channel worries about names while disrespecting the skill and intelligence of the people who invented the igloo.
American have like 20 words for feces, poop, caca, sh*t, crap, .... and the list goes on and on.... like doodoo...lol

Igloos are just temporary shelters during hunting trips etc. They're not houses.

Blocks wind... Which allows retained body heat in confined spot.

According to Yupic Eskimos of Western Alaska, Igloos are a fake invented by a Hollywood director for an early silent film. They just laugh at stupid "gussuks" who believe they were real.

Bruh you mad dumb if you think radiation uses convection to transfer heat... radiation is heat transfer between two solid surfaces and convection is heat transfer in a liquid (which air is classified as)

I’m actually Alaskan Native and I am Inupiaq, or Eskimo. The word Igloo actually means “home” but our actual word for it is something along the lines of Igluoq, but. when the Russians came they just made it igloo. also, we actually didn’t live in igloos. we made them for storage of animals that we killed and as a temporary home for hunting during the winter. Our more permanent home during the winter were semi-subterranean homes, which the permafrost in the ground and bones from dead animals helped structure it. i get all of this information from my ancestors and firsthand experience, and also because I worked at the Alaska Native Heritage Center. Message me if you’d like more info

+Donna Woodman I said this because I recently heard it in a podcast and I wanted to show off. I agree with you
Donna Woodman (3 months ago)
John B Ok, no problem. But what do we call them next year and a few years after that? I don’t know anymore what is going to offend some one. What do you call a person with really dark skin, or light brown skin???? I am afraid to call them anything. My sister and I are white but we often call each other white honkys. Lol
