yeah my screen is a mess

Teagan P lol i have the dark theme

Lol

these were my thoughts here as well thank you lol

could be a reason some can't see the things, some people call ghosts. some people can see them, some can't. Interesting thought. Maybe also, some people say the typical grey alien description, with the big eyes, aren't eyes at all, but, lens coverings for an eye behind that. Maybe they help them see things like this, that would otherwise be invisible, that would be interesting. Possibly why they say pets react to & can see spirits too.

@@Dropla very cool ideas maybe could be cool to integrate into fictional short story form could be fun

The bigger reason pilots don't wear polarized sunglasses is it will blank out cockpit displays.

Well, that and the fact that you don't really have to worry about glare from horizontal surfaces while flying.

@@brianwright9514 they see all the same horizontal surfaces and more, including glints off of other aircraft which are very important not to miss... so they can be missed.

for me it was the magnifying lens sheets stuck on windows in the 80s to see blindspots in vans. LOL

Sunglasses and car windows do things like that, probably because tempered car windows are made of multiple layers.

KZfaq has ALWAYS grayed the screen out when paused for me, across 3 PCs and 3 phones totally 4 operating systems and 3 web browsers. It's impossible to even do the thing they are asking you to do, it's like this video was made by 14 year olds.

hello people who scroll down to view comments on a video

Dang, I can't see it :(

Ehm what are you replying to? :-)

I know lol why do they say "some humans"?

What did you say? I can't see you!

Hello mam How are you Mind blowing Reply mam

joonatanu Wait, seriously? How does that work?

I'm not sure if that happens. Let me check

they dont become fully transparent, the middle filter just "refreshes" the polarization and allows some light (but not all) to make it through.

iau Say filter 1 is vertical, all light coming through it is now vertically polarized. Filter 2 is 45-degrees diagonal. Equal portions of the light is either let through or blocked (vertical light can be broken up into 2 diagonal components). Filter 3 is horizontal. Once again, equal portions of the light coming through the diagonal filter is either let through or blocked (diagonally-polarized light can be broken up into vertical and horizontal components). So you basically use the middle diagonal filter to "rotate" some of the light so that it can then pass through the horizontal filter. Edit: Keep in mind, vertical and horizontal are relative to your reference frame which is arbitrary. Nothing is inherently _vertical_ or _horizontal,_ it's more about measuring perpendicularity. A photon that is polarized perpendicular to its filter won't pass through. Otherwise, it has a _chance_ of passing through.

Its because the light only cares about the difference between both filters. The equation is cos^2(theta), theta being the angle between both filters. So if you have the two filters at 90deg from each other, then it gives you 0% light exiting. If you have a middle filter then you have 45deg from first to second which gives you 50%, then second filter to the last gives you 50% again, which is ends up with 25% light at the end.

@Emilio Vicente I think French is quite difficult to learn

KevinMcNoodles If you don’t wanna w8 in the mail you can salvage old laptop screen from their filters with a good cutter and a steady hand. There’s a tutor on Instructable

I agree, that is the best way to get them. I disassembled more old LCDs from defective notebooks with damaged screens like more than 10 years ago.

@Mikael Murstam, Thank you for additonal expanation!

Never noticed. But now look crazy doing the head tilt cross-eyed looking at my car window. I’ll keep an eye out for this though

omg I thought I was the only one, funny I didn't make the connection when watching the video but at least now I can learn more about it.

Yeah whenever I drive with polarizing sun glasses it gets so strong that I have to not try to look at all the different patterns of all the different cars on the road.

look at it through polarized film or glasses. Does the same thing as the knife and fork did in this video.

I was wondering what that was!!!

It's bell's thoerem yall

Mariano Ntrougkas but the point is that it’s so counterintuitive! From face value it seems non sensical. The 2 initial filters block all incoming light. So adding on in between shouldn’t change the outcome...or so it seems

@@Riiisuu I think it's counterintuitive because most people would expect the 3rd filter to be added to the end (after the light has been "cancelled"). If you put it in the middle, it would probably interfere with the cancellation, so then it's unsurprising.

Ryan Stallard but most people would think that it would increase the percentage blocked, not decrease

@@Riiisuu I hope most people would not have thought that. If you think you can increase the blocked light past 100%, I want what you're smoking. Would be sick. "Buy a Flashdark today!"

I discovered I can see it too - I saw what I would describe as "yellow wings" - but not the blue. Really cool

It's not that strange, some people have a lot more sensitive eyes to light in general. It's for that reason I wear sunglasses all year round.

And more! there are colours you see/experience/feel/smell while tripping on psychedelics like Psilocybin or LSD that just don't exist outside of a trip.

tilt your head

3d glasses are not the same at all lol

@@animeloveer97 i'm pretty sure they are tho? I mean those greyish ones.

@@animeloveer97 modern 3d glasses are polarized. One side is vertical and the other is horizontal, so one eye is only seeing half of the two slightly parallaxed 3d images. Some IMAX screen used circularly polarized light and one lens is clockwise and the other is counter clockwise, It creates a less perceived flicker in 3D films.

At first I just smiled at your "fast to dizzy" comment. But with unknown reason I followed it, and then I saw the yellowish dots! When I followed the "tilt slowly" instruction, I didn't notice the yellowish dots. Now I can see it. Thanks. :-)

yeh, it does do something odd... like it rotates in the opposite direction as your head rotates

I could see those dots without turning my head... at first i was like "what I can see them without turning my head"... and then I realized that was because I was lying on my side while watching the video xD
