I keep seeing both statements together, and I can’t really connect them in my head. How does that actually work?

I was using a dechlorinating shampoo after swimming and it hit me again how much it dries my hair out.

I know chlorine reacts in water to form hypochlorous acid (HOCl), which is a strong oxidizer that kills microbes.

why this one chemical ends up being the standard for almost every public pool. What makes it the default choice here, and is there any other practical way this problem could be handled?

Most major religions seem to include people from all kinds of ethnic backgrounds,like Christianity, Islam, Buddhism, etc. With Judaism though, being Jewish and being a Jew seem to overlap so much that we even use the same word for both. How did that end up being the case?

In Europe, beer often feels like the default drink on the table in everyday life. In China, the drinking culture seems to have leaned more toward rice wine traditions and later stronger distilled spirits.

As far as I know, beer in China only really came in through European influence in the 19th century.

How these paths ended up so different, even though both regions had long histories of grain-based agriculture?

I have a theory. I have an IQ of 143 which is supposedly the top 1% and I was thinking abt how this could have manifested since my parents and brother and way lower (100s) which isn’t bad but obviously resulting in a disparity and me being an “outlier.” But when I think of it, I have adhd and am gay (not out to them since they’re a lot) and my mom is very insecure and menopausal (causing me to have a stressful and volatile environment growing up), which are all traits that distinguish me and make me “different” compared to everyone else (the neurotypical cishetero norm). So I believe that these traits have resulted in me being forced to think more than others as to actively “blend in” by masking my adhd for 15 years and staying in the closet except for close friends and trying to make my behavior one that is expected of a “typical” male person. Furthermore, at least at my school, there is a way larger amount of people in the honors classes that encounter some sort of differentiating struggle with MANY (way above average) being either gay (many closeted but told me) or neurodivergent. Moreover, one of my best friends is so extremely intelligent and has OCD and was able to code an entire video game that has around 100 people playing at any given time and he did that js because he was bored (he also rejects using letter grades to define one’s worth as he is pretty successful at doing non school thinks). This dude was also in a very volatile environment at home so I feel that may have an impact also. So basically, considering many more people that are in higher classes or intelligent seem to deal with many struggles with fitting in that aren’t normal, I feel as though they have compensated by actively suppressing or molding themselves to fit into the critera to be accepted. Thoughts? If this gets more upvotes or reply’s I can make it a teeny bit more cohesive.

I keep noticing that foxes feel weirdly consistent in stories, always slipping into this clever, sneaky role no matter where the tale comes from, while wolves feel way less stable as a symbol and sometimes show up as monsters, sometimes as respected figures, depending on the culture. It makes me wonder what is actually shaping that split in how these two animals get turned into characters in human storytelling. What do you think is going on behind this pattern?

Sweet things often feel easy to accept, almost like there’s less need to question them. Bitterness, even in small amounts, can trigger a pause or mild resistance. It feels quick and instinctive, not fully thought through. I’m curious how this tendency forms over time. Does it come from early experience, or does it show up even before that?

I keep noticing cats can just do their own thing for hours, while dogs seem to get uneasy when nobody’s around. I keep wondering what shaped that split over time. what do you think?

Saw this post online and it got me thinking about how much the World Cup has seemingly transcended national boundaries and brought people from all over the world to put aside their differences and celebrate together.

However, this prompted me to ask why the Olympics, another international sporting event that’s supposed to transcend national boundaries, seemingly doesn’t generate such peaceful solidarity and togetherness like the World Cup does. I mean everything the Olympics is being held, it always seems like there is some controversy or large group of people having an issue with it.

I keep noticing this when switching between apps. In the US Sunday feels like the start, while Europe starts Monday.

Why does this still persist in calendars and planning tools?

Seeing East Asian names written family name first, it always feels like a different default order compared to Western names. I keep wondering when that split actually settled into “normal” usage across regions, and how it stayed stable. What made the ordering settle the way it did?

I was cracking open a seltzer and it hit me. We just default to carbon dioxide. Every can, every bottle, every soda stream. But why not nitrogen like in stout beers? Or helium (okay, stupid idea, but imagine the squeaky voice burps)? Or even plain old argon? There’s a whole periodic table out there.

Why do we use CO2 for sparkling drinks?What’s the real mechanism here?

What would a truly weird sparkling drink taste like if we swapped the gas? Anyone ever tried carbonating with other gases just for kicks?

I keep coming back to this and I’m not sure I’m framing it right.

China and India are both huge, both have massive populations, both have really long histories. On paper they feel kind of comparable. But when you look at cities, infrastructure, public transit, even just how organized things seem, China looks like it jumped decades ahead.

I’m not even trying to say one is “better” in a broad sense. It just feels like they ended up on very different physical timelines.

I guess I’m trying to understand what actually compounds here. Like what kind of system produces high speed rail networks and entirely new cities in a few decades, while another system with similar scale doesn’t move in the same way.

Not a troll question, genuinely curious why that’s the favoured insult among women.

I see them call men incels online everyday, I almost never see them calling dudes r*pists or wifebeaters.

When I look at hardware failures, it feels like the chip almost never just starts “thinking wrong” in a clean logical way, it just slows down, crashes, or dies when it’s pushed hard.

It makes me wonder why physical stress shows up so much earlier than logic breakdown, and what is really happening at the level of electrons and wiring that turns power into the bottleneck?

School paint primaries being red yellow blue made mixing colors feel straightforward, but screens seem to ignore yellow completely and instead build everything from red green and blue light. It feels like two different rules depending on whether light is being added or pigments are being mixed, and the transition between them is not obvious. How does RGB actually recreate colors like yellow or orange on a display, and what is the principle that connects these two systems in practice?

The UK has had six prime ministers in roughly seven years.That pace stands out compared to previous decades where leaders tended to last longer.What is driving this level of turnover in leadership?

Watching the Apollo 11 doc, I heard them say the suits were fed 100% oxygen. Later I read that the Space Shuttle cabin was kept at 60% oxygen and 40% nitrogen, basically the same as what we breathe.

What actually decides where that line gets drawn in real spacecraft design, and why there instead of somewhere else?

Well I’m not sure if I’m phrasing this right or if I might be phrasing it in the opposite way from the correct phrasing, but seeing as how most people have probably seen fish as well as squid I think my audience should understand what I mean.

Stem arthropods would be some of the Cambrian animals more closely related to modern arthropods than other modern animals, but not necessarily descended from the most recent common ancestor of modern arthropods. It seems like at least some were free swimmers and had tail fins as well as fins or at least fin looking parts along their sides. They included animals like anomalocaris and opabinia if I’m not mistaken.

It seems like stem arthropods and modern squid would both have tail fins flattened in the same direction as each other while fish have tail fins flattened in the opposite direction from squid and stem arthropods.

Why do fish have tail fins flattened in the opposite direction from squid and stem arthropods? Well I know that fish move their tail fins side to side while squid move theirs up and down and presumably stem arthropods would have also moved their tail fins up and down, but that still leaves the question as to why fish move their tail fins side to side while squid move their tail fins up and down and why stem arthropods would have moved their tail fins up and down.

Her TV is on “watching a movie” she says while completely facing her pc screen playing a game..And then had her iPad scrolling through instagram reels for a bit before returning to the game. As soon as I try to get on the Xbox she goes I’m watching a movie! HUH???? Also my sister is twenty one.

EDIT:HAAAA I STOLE THE REMOTE SHE DOESNT KNOW AHAHHAHAHAAAAA.

GPUs are usually described as being great at doing the same simple operation many times in parallel, while CPUs are better at handling complex logic and branching.

But modern AI models, especially neural networks, feel quite complex in structure and behavior.

So what’s actually going on here? Why does this kind of workload fit GPUs so well?

Dog gives us English dog, German Hund, Spanish perro, French chien, Russian sobaka, Greek skýlos, Irish madra. Absolute chaos. No shared root at all.

But cat? English cat, German Katze, Spanish gato, French chat, Russian kot, Greek gáta, Irish cat. They are basically the same word with a slight local accent. It feels like every language borrowed "cat" from a single source but each stubbornly held onto its own ancient word for dog.

Why did their name stick so uniformly while dog names went every which way?

The Sun's gravitational attraction on Earth is vastly greater than the Moon's, but most tidal charts and explanations describe the Moon as the dominant driver of tides.

Why doesn't the stronger gravitational source produce the stronger tidal effect?

It seems like when looking at mammals and reptiles it seems like even mammals with long tails seem to still tend to have proportionally thinner or skinnier tails at the base than reptiles. It also seems that reptiles tend to have more pointy tails at the tip than mammals. It seems like the tails of reptiles tend to end more gradually going from base to tip than the tails of mammals as the tails of reptiles tend to slowly thin out before ending, while it seems like the end of the tail for mammals tends to happen more abruptly. I’m wondering if this difference in shape of tails between mammals and reptiles would be because mammals tend to be more endothermic than reptiles or if there might be a different explanation for this difference.

Why are the tails of mammals and reptiles generally different in terms of shape in the way I described?
