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.

So much for saying that goldfish have a thee-second memory-span. The can also recognize people. (Wikipedia)

Don't tell Ted Lasso.

So when we say the American public has the memory of a goldfish, we're actually insulting the goldfish.

[–] [email protected] 4 points 4 days ago

TIL I am a goldfish.

And they grow to enormous sizes. Not "as big as the tank."

Myths like this have always made me kinda angry. Anybody that has owned fish for more than a few days could easily say that this isn't true at all.

But aside from that - animals simply wouldn't exist if they were that stupid. The world is a dangerous place, especially underwater. Not having even basic memory and pattern recognition would be a one-way flight to extinction.

Yeah, always felt like that this kind of myth is rather indicative of the intelligence of whoever actually believes it. Alas, most people probably don't think about whether it actually makes sense...

Even jellyfish can learn to spot and dodge obstacles, and they literally don't have a brain.

I didn’t know you could hear underwater.

[–] [email protected] 8 points 4 days ago

You’ve never put your head under water?

[–] [email protected] 6 points 4 days ago

Dolphins (and probably also Orcas) even call each other with their different names

[–] [email protected] 6 points 4 days ago

You can actually hear better underwater since water is a better conductor of sound than air is.

Whales and such make noises for a reason.

[–] [email protected] 9 points 4 days ago (1 children)

Fish do too. Fish have pressure sensors down the lengths of their bodies they use for navigation, sensing prey and predators, and communicating.

My gouramis are making clicking noises in their tank as I type this. Love those things.

Life is amazing. I love learning things like this

[–] [email protected] 19 points 5 days ago

So my memory is WORSE than a goldfish's. Cool cool

[–] [email protected] 14 points 5 days ago

I too have seen that MythBusters episode.
