The voice of the narrator is to me, one of the greatest voices on RU-vid( and maybe even Nebula). The way scientific topics are presented is also very good. This channel should be up there with legends such as Kurzgesagt. It needs more recognition. Also, the small mammals shown were so cute!

10:27 I just realized that I may have this "Hunter's response". As a kid I noticed that while playing outside in the snow and making snowballs bare handed my fingers would get very cold and hurt after a few minutes. But if I kept doing it for another 10 minutes or so, my hands would heat up again, allowing me to continue throwing snowballs.

@stephenfennell
@stephenfennell 3 года назад
@@phonn6935 I don't specifically know about polar bear fur but I have heard elsewhere that it is clear (i.e. transparent). Things that are transparent appear white if they are divided up into large numbers of surfaces all at slightly different angles. Water is transparent, but if divided up into millions of droplets with surfaces at countless different angles, as in a cloud, photons trying to get through that cloud will be reflected at billions of angles off every part of a droplet's surface that presents a shallow angle to them. The photons are now bouncing around between the droplets at random angles. If there is an object such as a plane behind the cloud, rays of light that set off in a straight line from that plane towards your eyes will get diverted on all sorts of random paths hither and thither through the cloud before they get to your eyes. All you see are zillions of photons reaching your retinas from very random locations, some from the plane's wing, some from the cockpit, some from a patch of blue sky, and lots actually from the sun (even if the sun is way off to the side). The photons include photons of all colours, so when you mix all the colours together the total effect you see is whiteness. So a cloud of water droplets looks white, even though water en masse is clear. So I would not be surprised if each individual polar bear hair is clear and yet when seen in large masses appears white. Sorry, my comment got extravagantly long!

Some yeara ago, Russian scientists in Siberia found a well preserved woolly mammoth frozen in the permafrost. They commented that it was so well preserved that its flesh was still edible. I thought about this. The comment begged the question 'what sort of food did the poor scientists have that they would consider eating the mammoth'.

Torpor and Hibernation are quite different.. Bears go into torpor and animals in torpor wake quite easily, animals in hibernation like a hedgehog will not wake up and you could hurt them by picking it up or moving them while in hibernation. The bit of info at roughly 4:45 made it seem like it's an interchangeable word, and it's not, they're quite different states.

@MrMarinus18 Год назад
It isn't totally accurate that frostbite is a death sentence to all life. Needletrees are frostbitten every year. They have adapted with gaps between their cells for the ice to expand into. The ice though does lock down their cells so they can't grow during it or do much. It's kind of a plant form of hibernation. During the summer they can grow again. That's why they grow so fast and can exist so far north.
