And is it always better to do one or the other? Or is it situation dependant?

If ever? Like when a human throws water at a bug, I always imagined from the bug’s perspective it would be a natural disaster like how we perceive storms.

Because sometimes a cat doesn’t even seem to notice a human arm belonging to the human in front of them as a whole torso, or are they all smarter than this?

So to extend the question, it would be: (1) do they at least recognize a human limb belonging to the human agent? (2) They couldn’t possibly do this when a human uses an external tool, or could they? (3) Further, would looking into this give any insights on how we humans understand causality when we perceive events?

Thank you in advance to smart people

I’ve noticed how often the same types of characters show up in mythologies from cultures that were very far apart.

There always seems to be a thunder god, a trickster, fairies, a giant serpent, gnomes, an underworld ruler or a hero who has to defeat some kind of monster. Did these stories spread between cultures over time, or did people independently invent similar characters because they were dealing with the same fears and parts of nature?

What prevents an airplane's black box automatically sending all its flight data to the cloud while the plane is flying, or immediately after a crash? Why do investigators still have to recover the actual black box?

I am learning js, html, and css, and was recently told that front-end isn't "real programming". What languages are used in back-end, and whats the point if you can host on github pages? Thanks in advance!

e: To clarify, I am familiar with the idea of invasive species. I mean how does a species that is introduced into an ecosystem become incorporated into the ecosystem, neither going extinct nor going out of control.

I thought dopamine increase = more anxiety and racing thoughts?

I've noticed that when I accidentally get a shallow cut (especially when there's no bleeding) they tend to hurt more, than when I get a deeper one. So I'm curious, why's that? Does the bleeding have something to do with it?

like what's actually happening and how does it work

Gatorade, Pocari, etc

Hi! I am not talking about raw food that get cooked, because I can understand in that case, but specifically about the difference in taste between cold cooked food and warm cooked food or also drinks. Why does some ingredients taste stronger/weaker/more salty/more spicy depending on their temperature?

well i guess a few of us have seen there has been a breakthrough regarding this JC being false all this while. and this was backed by some highly qualified person in mathematics. its wild actually if its true.

I looked at the other JFK-related ELI5 threads, but nowhere I found this particular question answered. Thank you for your thoughts.

have went to places like big aquarium with sharks and when the divers or staff are feeding the sharks never attacks them, i looked online if there are such cases and i dont see any records of attacks either

I have seen divers go right next to the sharks and they dont ever nibble too nor was there any incidents

I have a wifi modem (from Bell fibre). It doesn't cover the entire house, and certainly doesn't reach the basement where I need it the most. I asked a technician what my options were, and he mentioned getting some wifi mesh devices, and then turning the modem to 'bridge' mode.

I have a basic understanding of wifi. The modem turns the wired signal into wireless. I understand that if I just plug in another wifi emitter, it makes a separate wifi network. So what exactly is bridge mode? What does it do? Do I have other options too?

EDIT: Thank you all for your input! Everyone's so helpful! Obviously there are many follow up questions, which I'll ask in comments :) Thank you!

eg. some pills work better than others that may have little to no effect, but all have different ingredients..

what is the acutal ingredient or element that boosts happy hormones (serotonin/dopamine) in the brain?
