What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



Rule 2- Your post subject cannot be illegal or NSFW material.

Your post subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Posts and comments which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding non-TIL posts.

Provided it is about the community itself, you may post non-TIL posts using the [META] tag on your post title.



Rule 7- You can't harass or disturb other members.

If you vocally harass or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.

For further explanation, clarification and feedback about this rule, you may follow this link.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

Its not about wavelength but about peoples ability to perceive and distinguish.

Blue is a rare pigment in nature so in most ancient cultures its often being categorized as a shade of green.

To give you an example of the opposite:

The Himba tribe of Namibia is known for their unique perception of color, particularly in how they differentiate shades of green. Research has shown that the Himba are more adept at distinguishing between various shades of green that many “civilized” might see as similar.

I don't actually care about the linguistic side of it; we call a green traffic signal a blue light here in Japan (and the new ones are more blueish, but the old ones were much more green). I think Vietnamese and other languages do that.

When I skimmed the article, it was arguing that people literally could not see the blue, or at least was worded thusly where I looked before noping out of there. The literal title is "Hidden Hue: Why Ancient Civilizations Failed to See the Color Blue?" Not "failed to give it its own name" but "failed to see".

Edit: punctuation.

Clickbait be clickbait and half the site is probably ai generated. I wont defend the hyperbole.

Theres is a debate you can have to what attributes to seeing in relation to perception. Our mind has a lot of tricks to get around the restrictions of our eyes.

Its a shame how enshitification erodes this conversation.

Yeah, there are definitely interesting conversations to be had. I actually saw an interesting video on the vision/linguistic side. I was just trying to find it to share but, speaking of enshitification, yoube's search is ass. Why can't I search in my subscriptions?!
