If you are outdoors in a cold polar region during the day what will keep you warmer?

Details: The color is on the outside, the inside you can assume is a neutral gray for simplicity.

Black absorbs more EM than white, but black objects also radiate more. All matter above 0 degrees K radiate EM known as "black body radiation". Black objects radiate that energy more quickly than white objects, so they get cold more quickly.

"During the day in a polar region", means that in the dead of winter it's dark out, even at noon. (The question didn't specify the season.) If the sun is below the horizon or very low in the sky (i.e., traveling through a lot of atmosphere), the solar EM wouldn't be much, in which case the black would radiate more energy than the white, and the inside would get colder.

Also, even if there is some sun, the surface of the coat is on the outside of the insulation, so any heat that it absorbs would quickly radiate back out into the air before that heat could penetrate the insulation to help warm you up.

I didn't look any of this up, it all from memory so I can't guarantee it's accuracy.

@Pat That last sentence looked a bit off to me. Isn't it "I didn't look any of this up, it's all from memory so I can't guarantee its accuracy."?

@freemo

my answer 

@trinsec @freemo

Yeah, I kind of scrambled my plurals/possessives on the "it"s.

Dyslexia seems to be acting up at the moment for some reason, I 'm making all kinds mistakes in my writing...

my answer 

@Pat

Hmmm dyslexia. I wish i had that "excuse" :)

@trinsec

my answer 

@freemo You already have the excuse that you're being you. :P

@Pat

my answer 

@freemo @trinsec

A lot people have undiagnosed dyslexia. I've noticed that you often confuse things like "your" and "you're". You may have it and not know it.

my answer 

@Pat

I use your by default mostly because I type to fast and dont review what I write. Couple that with the fact that i got into the habit by typing on my phone where an apostrophe is a bit tedious. That particular error, as most of my errors, are largely due to not caring and typing as fast as I can since i dont find the medium to be critical for correctness.

My formal writeups, as well as my blogs, tend to have very few errors since I proof read them.

That said my natural rate of errors has been unusually high the last 2 years since my injury and COVID largely due to the extremely high levels of stress I've been under which seems to effect the prevelance.

@freemo @Pat

Oh man...

Ok the real challenge here is to find a sentence without mistakes. ;)

my answer 

@trinsec

hahaha valid. Honestly if i could actually edit posts on here there would be a lot fewer of them. At least on matrix i will occasionally correct my mistakes. Here I see them but usually after i already posted and only once i reread it when going over replies.

@Pat

my answer 

@freemo I do tend to delete and redraft in the first minute or so, and if nobody's replied yet. Otherwise it is a 'oh shit, oh well, move on, next time better'.

@Pat

my answer 

@trinsec

I used to do that but with 20K some followers it pissed off a lot of people, way more than just keeping the typos.

@Pat

my answer 

@freemo Heh... valid point.
That said, I tend to take like 10 minutes per email just to make sure my answer makes total sense and contains no mistakes. I tend to do the same for my initial toots often as well.

@Pat

my answer 

@trinsec

If i actually paid that much attention to my toots I probably wouldnt toot very often. Then you would cry all the time and I dont want to make you cry.

@Pat

my answer 

@freemo Funny.. I cry all the time you do post! :P

@Pat

my answer 

@trinsec

Thats ok, I'm usually crying when I post too, as well as any other time :)

@Pat

@trinsec @freemo

When spell-checkers came out, it was a godsend for me. If I left my spelling mistakes in my writing, you wouldn't be able to make out half of what I was saying, it's so bad.

A lot times I can't find the words in the dictionary because I can't spell it close enough to find it. I use Google a lot now because they have AI/phonetics algorhtms.

(I left that last word misspelled, just so you could see how I tried to spell it unassisted so you get a feel what I face with this issue. It's a real pain.)

@Pat

I dont use spellcheckers. I dont need that kind of negativity in my life!

@trinsec

@freemo @Pat Heh, and I usually turn off spellcheckers... because I absolutely hate the squigly red lines! They actually distract me!

I'm still trying to figure out where I can turn it off in outlook.office.com because it's English-oriented and my conversation language is Dutch.

I guess I'm teaching that stupid dictionary a lot of Dutch words now... :P

@trinsec

50% of the time my spelling is such a bastardization the spell checker has no idea what I am trying to say. the other half of the time my vocabulary is so advanced it doesnt even know the word I am trying to say.

@Pat

@freemo To be fair, you probably also don't know that word you're trying to say. ;)

@Pat

@trinsec I know everyword I am trying to say, and spell it perfectly. Its not my fault that the dictionary can't keep up with the latest spellings!

@freemo @trinsec

>the other half of the time my vocabulary is so advanced it doesnt even know the word I am trying to say.

I've wasted a lot of time trying to track down the "correct" spelling of a work, only to find that I had it right all along and the spell-checker just didn't know it.

@Pat

yea oddly enough some of the more advanced words I get right more often than the simpler ones.

@trinsec

@freemo @trinsec

Is that everyone gets pissed off at me when I try to correct their grammar?

@Pat I appreciate the correction if it's informative. I mean, how else are you gonna learn?

But I know people who absolutely hate to be corrected in any way possible. Can't always win, I suppose.

@freemo

@trinsec

I hate to be corrected. If I am corrected I cant say I'm always right anymore. Why would anyone want to be wrong!

@Pat

@Pat

That would still make me right only 50% of the time. If I am never corrected then I'm right 100% of the time.

@trinsec

@Pat You don't get his thinking pattern... he just wasn't wrong to begin with. ;)

@freemo

@trinsec

I'm starting to think you might be the smartest person on this server :)

@Pat

@freemo Oh, really? Even smarter than you? I'm so honored. ;) And since you're always right, it must be true!

This is why Trumpian delusion has so much mass appeal.

my answer 

@Pat Heh, real dyslexia, or a 'haha, silly me, must be dyslexia' type of dyslexia?

@freemo

my answer 

@trinsec @freemo

Never diagnosed officially, but I definitely have a language issue... mostly spelling, homophones and general social communication.

re: my answer 

@Pat @freemo I wonder from where you get that black objects radiate energy more quickly

re: my answer 

@xarvos

Its established science. The physics term is called "blackbody radiation" and describes how black things radiate heat and likewise how white things are poor heat radiators.

@Pat

re: my answer 

@xarvos @Pat @freemo Things are black because of their interaction with radiation. That interaction goes both ways. If light hits an black object, it is absorbed in the high-energy states, and those states quickly disperse to lower energies. If the black object becomes hot, those high energy states get occupied, and start sending out light because the absorption of light is reversible.
