ELI5: why doesn't the ocean suck you dry through osmosis

Since there is a higher concentration of salt in the ocean than your body shouldn't it draw moisture from your body into the ocean dehydrating you?

ELI5 Why don’t alcoholic drinks get stronger on the shelf?

Say I buy a spirit and keep it in my fridge for a few weeks/months/years waiting for a special occasion to open it. Why doesn’t it keep fermenting and get more alcoholic as time passes?

ELI5: Why don't we milk pigs?

Basically every other domesticated mammal if bread for both meat and milk. Not just cows and goats, but sheep, and even horse and camel milk are a thing. But I never heard of anyone milking pigs. Why is that?

ELI5 box fan venting best method

If I have a box fan and it’s colder out side than inside what is the most efficient way to move the air. Should I point the fan inside or outside. Should the fan be close to the window or a few feet back. Do I want to seal around the fan or no. Do I want more than one window open on the other side. And why I would like to know the science in a simple way.

ELI5 why does decompressing your back by leaning on something feel "good"? Is it something that learnt and because people say it's good we take the dull pain as a sign of it working or is it something else.

ELI5: Girl Handwriting vs. Boy Handwriting

Why do all girls (exceptions aside) have so much better handwriting than boys? We (boy) all took the same classes growing up, and did the same homework, so why do girls, women, etc., all tend to have better handwriting? I can’t accept “practice” as an answer because I remember practicing a good bit as a kid and I’d consider myself pretty artistic, yet my handwriting stands out as clear “boy” handwriting. There has to be some sort of biological explanation, right?

ELI5: Why, in the English language, meat has a distinct name for each animal it comes from

It seems that most languages out there just go by a variant of <animal>-meat when referring to meat from specific animals, but in the English language, they have distinct names (beef, pork, veal) that do not derive from the animals it comes from. What do these names mean exactly?

ELI5 : Trying to understand how how something that tends to infinity doesn’t actually reach what it’s tending to

howdy, dumb university student here, never been too good at math but my course requires me to take a compulsory module. It’s not required for me to know this but itll at least help calm my confusion.

We know that asymptotes are points on the cartesian plain that the graph/function will never touch. We are told that it ‘infinitely’ tends to the asymptote but never reaches it. My question is that if it actually infinitely tends to something, shouldn’t it eventually reach it?

I think i might be making some sort of logical error, but the best (i think) ive seen it described is if you’re 5m away from a wall and your distance halves each time you never ‘actually’ reach zero, just a number close to zero. I guess that makes sense, but i want a second (or several) opinion/s.

please don’t berate me :,)

ELI5: This is a two for one but related, Digital-to-analog converter and built-in amplifiers

I get what all the words mean separately for Digital-to-analog converter, but have no clue what it means in practice, like why would I want one, what makes it good? I also get that built-in amplifiers combine something? Mabey. But like again why is it good?

Context: this is for me doing research on a digital audio player.

ELI5: Why do we sleep?

What is the purpose of sleep, and why do we need it? If we just consume enough calories, and drink enough water, surely this will fuel our bodies and give us energy? Why, therefore, do we need to sleep?

At the moment I see Palantir in the same breath as a spy software or intelligence software. What exactly is it, and why is it so special?

Is it like in the movies where this one software can connect to any satellite, any database or any other resource?

They seem to have a lot of roof area, and it seems like a logical power choice, but I never see solar panels in pictures of these facilities.

ELI5: How is the phrase "Imagine that everyone is naked" supposed to help you perform?

In countless movies and medias or such, there's always this phrase that someone would say to help a character about to perform, "Imagine the audience is naked!", and I never understood how it's supposed to calm them. If anything, wouldn't a shy performer get even more nervous? Hell, I've also seen that EXACT scenario play out in other medias, where the performer fucks it up due to that imagination. In what way is that advice meant to help? Is it even an actual tidbit in real life?

ELI5: Have we "locked in" English due to the Internet?

A lot of languages developed over time due to geographic separation between areas. With the globalization of the language, with lots of documents that establish how English is spoken, would we expecting that English thousands of years from now (assuming we live that long) to be largely the same?

Edit: I should have clarified. I too like to meme, so I know that we'll always be coming up with new words/slang. But what I was really wondering about was the grammatical structure. Even for memes, most of it is inserted in sentences that match standard sentence structure.

ELI5:How do our brains not fry themselves when we use our brains?

ELI5 with our brains neurons somewhat making electricity with things like action potential or chemical synapses leading to some electricity in the brain itself last I checked from things like getting struck by lightning feeling the human body with electricity tends to be a bad thing and often deadly thing, so how do our brains get away with the charge created by things like previously mentioned action potential or chemical synapses? Is there not enough of a charge being produced or is something else at play here?
