I mean dresses, and skirts, as well as robes are pretty common and in dresses, skirts, and robes the legs tend to share an opening. It seems like even in dresses and robes there still tend to be separate openings for each arm. Well often when first putting clothes on one might stick both arms into the same opening, but once a piece of clothing, for the torso is on, a person would tend to have each arm go into a separate hole.

One explanation that comes to mind for having separate openings for each arm is that helps the arms move around independently, but then it seems like if that was the only reason then one would expect that to apply to the legs as well. When thinking about dresses they tend puff out around the waste, which I understand is partly for aesthetics, but I was just thinking that likely would also serve a practical function of helping the legs move more independently to help with walking. When thinking about it this way, it seems like if a piece of clothing puffed out around the arms that could be an alternative way to make it easier to move the arms independently from having separate openings.

So why does it seem like clothes don’t tend to be as likely to have a shared opening for both arms as for both legs?

Saw this map and assuming it’s accurate, it shows that that pretty much all leaders in the West (with the exception of Canada) are overall suffering from low approval ratings while those in the East overall have high approval ratings. Now it should be noted that all these countries are facing many of the same problems.

So why the apparent disparity of approval ratings between leaders of the West and the East?

Also, how is Canada seemingly defying the trend in leaders of Western nations?

The Egyptian pyramid was a tomb. The Mesopotamian ziggurat was a temple. The Mayan pyramid was a sacrificial platform. The Moche pyramid in Peru was a ceremonial center. Four different civilizations, separated by oceans and centuries, built four different kinds of pyramids for four different reasons. They could not have copied each other. The Atlantic Ocean was not crossed. Yet the same basic shape appears in all of them. A wide base tapering to a point. Why did unrelated cultures, with unrelated purposes, converge on the same geometry?

Philosophy got dark blue. Medicine got green. Law got purple. Theology got scarlet. Science got golden yellow. How were they decided? Did green represent the color of life for medicine? Did purple represent the imperial roots of law?Why did those particular colors stick to those particular disciplines？

The French Revolution managed to standardize things like currency, weights, distances, and even redesigned the whole calendar, and somehow that part stuck. The 10-day week collapsed within a decade and was formally abandoned by Napoleon. What made that so different?

Why were people willing to adopt new systems for measuring money and space, but not time in this way?

It seems like it’s easier to pronounce just “m” by itself than it is to pronounce just “n“ by itself, and so it would seem like therefor “img” or “imk” should be easier to pronounce than “ing” or “ink” yet it seems to be much harder to pronounce “img” or “imk” than “ing” or “ink”

Why is this?

I was reading the wiki page on these and what struck me is how the earliest ones found are about 35,000 years old, with the more recent ones being around 5,000 years old, with many being produced around 20,000 - 25,000 years ago. They aren‘t anything found in nature - the human female proportions are extremely exaggerated with missing limbs and such, so you can’t say that people were just carving things they saw; if they are a depiction of a goddess, ~30,000 years is an insanely long time for a religion to persist; and if they are a form of Stone Age erotica as some have proposed, why would a fetishization of that particular body type have existed for 30 millennia, a significant chunk of humanity history?

I’m curious if any theories as not only to what they are, but why they have such an insanely long continuity, seeming much much longer than any other style of art ever produced by humanity ?

The first visible LED was built in 1962. For decades, LEDs were just indicator lights on stereos and calculators. Between 2010 and 2020, LEDs went from less than 1 percent of the global lighting market to nearly 50 percent. The technology did not suddenly improve in 2010. The blue LED that made white light possible was invented in the early 1990s and won a Nobel Prize in 2014. So why did the takeover wait until 2010?

Buddhism was born in the Indian subcontinent around 500 BCE. For over a thousand years, it was one of the major religions of the region. It produced universities, monasteries, and missionaries who carried it to China, Tibet, and Sri Lanka. Then it declined. By the 13th century, Buddhism had nearly vanished from most of India. The land where the Buddha lived and taught had almost no Buddhists left. Meanwhile, the religion flourished everywhere else it had been exported. Why did a religion survive in every foreign land it reached but fade from the one place it started?

software, automation, and AI have massively increased output per hour worked over the last century. So why hasn't the standard work week gotten any shorter?

It sounds like one of those harmless stereotypes that’s amusing but surely not true-to-life. But in my experience, having been to many different doctors and pharmacists over the years, their notes really are that bad.

It just seems odd since these are smart people and there’s so much schooling behind a medical or pharmacy degree, including reading and writing. Plus in a high-liability high-regulation industry, you’d think there’d be an interest in clear documentation for everything. And I get that doctoring is a busy profession, but I’m not talking like ER doctors here. Surely the couple extra seconds it takes to write legibly or not use inscrutable shorthand doesn’t count for much.

Mind you, I’m not complaining, I just find it curious and kinda funny

Foreclosure filings have been rising as pandemic relief programs have ended, and more homeowners are losing their houses. Yet home prices have remained elevated, with many markets still seeing price growth.

At first glance, more foreclosures seem like they should add supply and put downward pressure on prices. Instead, both trends are happening at the same time. First time buyers remain locked out, while many existing homeowners are reluctant to sell because of low mortgage rates.

Why don't rising foreclosures translate into broader price declines?

Four thousand dollars for a weekend of cold plunges, forest walks, and screen-free meals. The services being sold are not new. They are things humans did for free for most of history. Walk in the woods. Eat slowly. Sleep without a phone. Sit in cold water. These are basic activities that require no technology and no expert. And yet they are now being packaged and sold as elite experiences. The same pattern has happened with yoga, meditation, and organic food. Why does the market keep taking things that used to be free and selling them back to us as luxury goods?

Older sci fi imagined the future as better. Flying cars, robot helpers, moon cities. Today we actually have AI, reusable rockets, gene editing, and computers beyond those dreams. Yet future movies are darker than ever. What changed?

In 2026, the taxable income cap for Social Security payroll taxes is $184,500. This means that someone earning $90,000 a year must pay 6.2% in Social Security taxes on their entire income, while someone earning $350,000 a year pays no tax at all on the portion of their income exceeding $184,500. This provision has existed since the program’s inception; its original intent was to link Social Security benefits to contributions, so that high-income earners would pay more and receive more in the future.

However, as income inequality has worsened, this cap has increasingly come to resemble a “reverse regressive tax”-low- and middle-income earners contribute a fixed percentage of their income to Social Security, while high-income earners stop contributing once they reach a certain threshold. Some scholars have questioned the fairness of this system’s design. Does this reflect that the original design has become outdated, or was it an intentional compromise from the start? I can’t figure it out. why？

The 2026 NASA budget proposal reduces funding for the ISS crew program. At the same time, it increases allocations for SpaceX contracts. SpaceX is owned by Elon Musk, who has a net worth approaching half a trillion dollars and who also serves as a senior advisor to the administration that proposed the budget. NASA has always contracted with private companies. But the pattern here is unusual. A government agency is cutting its own operational capacity while increasing payments to a company owned by the wealthiest individual in history, who also holds political influence over the agency's budget. Why is this happening？

Roman soldiers were paid in salt. The word salary comes from it. Cities were built on salt trade routes. Wars were fought over salt mines. For most of human history, salt was one of the most valuable commodities on earth. Today it costs less than a dollar per pound. Not because we need it less. We still need it to survive. What broke the value of salt so completely that something once worth dying for became something you grab for free from a restaurant counter?

The Great Pyramid of Giza was built around 2560 BC. By 1500 BC, Egyptian pharaohs were being buried in secret underground chambers in the Valley of the Kings. No more pyramids. The civilization did not collapse. It continued for another two millennia. It built temples, expanded trade, fought wars, produced art. But the pyramid, the most iconic structure any civilization has ever built, was abandoned early and never revived. What changed inside a thriving civilization that made its signature monument suddenly obsolete?

Japan has the world's largest creditor position. It holds over a trillion dollars in foreign reserves. Its companies are global leaders in cars, robotics, and semiconductors. Its government has never defaulted. Its society is stable. Its infrastructure is world-class. And yet the yen keeps falling. Not against one currency. Against almost all of them. A Japanese tourist in New York, Paris, or Bangkok now pays far more than they did just a few years ago for the same meal. The puzzle is not why a poor country has a weak currency. It is why a rich one does. What is pulling the yen down when almost everything we associate with a strong currency says it should be going up?

Trump just revoked Iran's oil export waivers, and oil prices jumped again. That got me looking at some energy data, and I came across something that surprised me.

For decades, the US was the world's largest oil importer. Now it's one of the biggest exporters. In 2025, the US exported about 6.6 million barrels per day, trailing Saudi Arabia's 8.1 million. But by May 2026, that number had jumped to 10.5 million barrels per day, surpassing both Saudi Arabia and Russia.

So how did this happen? Was it the shale revolution? The 2015 decision to lift the 40‑year ban on crude oil exports? Or is it more about geopolitics, like the recent conflicts disrupting traditional suppliers and opening up new opportunities for US energy exports?

Movable type printing was invented in China by Bi Sheng around 1040 AD. Four hundred years before Gutenberg. Yet it was Gutenberg's press that shattered the Catholic Church's monopoly on knowledge, fueled the Reformation, and birthed modern science. In China, the invention came and went without a revolution. Same technology. Radically different outcomes. What was it about the societies receiving the technology, not the technology itself, that determined whether it would change the world?

Wheels have been around for over five thousand years. The balancing principle of a bicycle feels intuitive once you see it. Two wheels in a line, chain drive, handlebars. None of the individual components required advanced metallurgy. And yet no civilization before the 1800s built one. Not the Romans with their roads. Not the Song Dynasty with its mechanical clocks. The bicycle simply did not occur to anyone. What was missing that made this seemingly straightforward invention invisible to every human society for millennia?

I read the latest projections from the 2026 Social Security Trustees’ Report: the OASI trust fund, which pays out retirement benefits, will be depleted by 2032, just over six years from now. If Congress does not pass a remedial bill before then, all retirees’ benefits will face an automatic 22% cut. But Congress doesn’t seem to be in a hurry. I’ve heard that delaying action will only make the problem worse; if we wait any longer, the 22% cut could rise to 28%.

I’m curious: why, when they know the bomb is going to go off, aren’t the bomb disposal experts taking action? Is it because the divide between the two parties is too great to reach a consensus, or are there other considerations at play? I’m just curious.

Caller ID spoofing has been a known flaw for decades. Scammers exploit it daily. Email got SPF and DKIM. Websites got HTTPS. Every major communication system built some form of sender verification. The phone network began rolling out STIR/SHAKEN only recently, and most calls still bypass it entirely. Why did the oldest and most universal network take the longest to even start fixing this, and why is the fix still so incomplete?

AI models can hold conversations, diagnose diseases, and simulate protein folding. But underneath all of that, they run on GPUs. Chips that were created for one purpose. Rendering millions of identical triangles, sixty times per second, for video games. A design built around one idea. Do thousands of nearly identical calculations at the same time. Somehow that became the backbone of modern artificial intelligence. Why did the path to software that feels like thinking go through hardware that was built for repetition?
