People usually count in base 10, while digital computers typically represent information using 1s and 0s. The same numbers and information can be represented in different bases, yet binary became the standard for modern computing.

What made binary the system computers came to rely on?

Went to a show last month and noticed a few people near me wearing camera glasses. I couldn't tell when they were actually recording. They were watching the show, talking to people, dancing, whatever. No phone held up, no obvious camera pointed at anyone. If I hadn't noticed the little light on the glasses, I probably wouldn't have thought about it at all.

I get the appeal. Hands free photos are cool, and most people buying these aren't trying to creep on strangers. That's not really my issue.

The problem is the default. With a phone, you usually see someone raise it, point it somewhere, and hold it there. You get a social cue that a camera is pointed at you. With glasses, the person can just keep looking at you normally. You don't necessarily know when the camera is running.

That's a pretty big change in the social rules around recording people, even if the person wearing them has completely normal intentions.

I'm not saying camera glasses should be banned. I just think venues are going to have to decide what the rules are before everyone quietly gets used to being recorded.

The Mongolian steppe held, by most estimates, well under a million people, a tiny population compared with the large settled states to its south and west. Yet in the early 1200s, Temüjin united rival Mongol and Turkic steppe peoples and built a military force that rapidly expanded beyond the steppe.

Within a few decades, the Mongols had conquered the Jin dynasty in northern China, an empire of perhaps 50 million people, defeated major powers in Central Asia and Iran, and pushed as far west as Eastern Europe.

They mobilized large numbers of highly mobile cavalry, sustained long campaigns far from their homeland, and repeatedly turned conquered peoples and resources into additional military and administrative capacity.

How did a relatively small, sparsely populated pastoral society develop the ability to mobilize and expand on that scale?

In 1971, D.B. Cooper hijacked a plane, took $200,000 in ransom, and disappeared after jumping from the plane over Washington. He was never found, which is a big part of why the story became so famous.

But suppose his body was found a couple of years later, along with the money.

Would that make the story less interesting because there’s no longer a mystery about what happened to him? Or would the fact that he actually died during the jump make the story even more famous?

Say it’s a single strike and there’s no second launch. The government behind it denies ordering the attack, but the US isn’t sure whether that’s true.

Would the US have to respond immediately, or would it spend time figuring out who actually gave the order?

If retaliation could trigger a larger nuclear war, how much certainty would be enough?

The Guardian had a piece on age gap discourse in June. One thing that stood out was how casually people now describe Billie Eilish, Florence Pugh and Beyoncé as groomed by older partners.

Beyoncé is a strange example to use. She's been famous for decades, has her own money, her own career, and a life that clearly doesn't depend on her husband. You can dislike their age gap if you want, but what exactly are we calling grooming here?

Grooming involves things like isolation, dependency and control. You can't establish any of that just by subtracting one person's age from another.

And I get why people are more alert to age gaps when someone is nineteen and the other person is thirty two. There's a real difference in money, housing, experience and who can afford to walk away. Those things matter.

But online, the concern doesn't seem to stop when the younger person gets older. Someone is thirty, has their own career and money, and people are still calling them groomed because their partner is older.

At some point, are we talking about actual grooming, or do we just dislike the relationship?

Because if every age gap gets called grooming, the word becomes a lot less useful when someone actually needs help.

I keep seeing Western countries called racist or intolerant, and I get that they have problems. What I don't get is why the things they do to be inclusive seem to count for so little.

Take Britain. It's a country where people from all over the world live, where refugees can receive housing and support, and where someone from a completely different background can build a life. Yet when Britain comes up in discussions about racism, it's usually about what it's still doing wrong.

When does any of that count for something?

I also think people forget how much more visible race-related arguments become in a multicultural country. If you have people from dozens of different backgrounds living together, you're probably going to hear more arguments about race than in a country where almost everyone is from the same background. That doesn't automatically make the first country more racist.

What bothers me is that Western countries seem to be judged by everything they haven't fixed yet. Their progress is just treated as the starting point.

And when people compare the West to other countries, the comparison often disappears completely. We're expected to keep improving, but apparently asking how other countries are doing is somehow beside the point.

I think Western countries deserve more credit for being relatively inclusive, even if they're far from perfect.

In 1978, a quiet tax change created the rules that allowed the 401(k) to take off. Companies increasingly froze or replaced pensions. Retirement became a stock market bet, and Wall Street collected fees on every dollar.

But what if Congress had said no?

Strengthen pensions instead. Full vesting after two years. Credits that travel from job to job. A federal backstop so promises made are promises kept.

Retirement would be a paycheck again, not a gamble. Elderly poverty could fall. Wall Street would lose a river of fees. Workers could change jobs without starting at zero.

The downside is real. Pensions can fail too. Companies can go bankrupt, funding can fall short, and taxpayers can end up carrying the risk. Golden handcuffs might lock people into bad employers, and startups struggle to hire.

Would portable pensions have kept retirement a promise, or buried companies under debts they could never keep?

I was at a bar last month. An actual bar, dark wood, taps on the wall, the kind of place where the jukebox has an explicit lyrics option for a reason. A guy two stools down was telling a story, volume up, some colorful words in it. A dad holding a toddler walked over and asked him to watch his mouth because there were kids present. Saturday night, 9pm.

The guy apologized. I remember looking at that toddler and thinking, nobody here chose to make this a family space.

Somewhere along the way, “I'm a parent” started getting treated like a reason everyone else should adjust. Lower your voice. Change the channel. Soften the joke. Make the restaurant more kid-friendly. And sometimes the expectation reaches places that were never really designed around children in the first place.

You'll see a four-year-old at a 10pm R-rated movie, a stroller at a crowded brewery, or kids running around a restaurant where people came for a quiet dinner. Then the argument becomes whether everyone else should be more understanding.

To be fair, some of this is a correction we needed. Changing tables in men's rooms, clean high chairs, accessible entrances, places where families aren't treated like an inconvenience. That's all good.

But there's a difference between making public life less hostile to families and expecting every shared space to accommodate children by default.

Deciding where your kid can handle going is part of parenting. A bar doesn't have to become kid-friendly because you brought your kid there. Sometimes the answer is simply, “this probably isn't the place tonight.”

And yes, villages are great. But villages volunteer.They don't get drafted.

I recently learned that horses were reintroduced to North America by Europeans, which made me wonder about how deeply horses seem to be woven into the mythology and spiritual traditions of some Native American peoples.

I understand why horses became important. They were incredibly useful for travel, hunting, warfare, and trade. What surprises me is how quickly a relatively new animal could become part of stories, traditions, and spiritual beliefs, to the point that horses are now so strongly associated with Native American culture in the popular imagination.

How does an animal go from being newly introduced to becoming such a deep cultural symbol?

Imagine you walk into the voting booth and every candidate is just a numbered list of positions on the major issues. No name, no party, no picture. The positions are shuffled around so you can't figure out who's who.

You'd actually have to read what they believe and pick the one closest to you.

Part of me thinks this would be great. A lot of people probably vote based on party, personality, or just recognizing a name. Take all that away and maybe people would pay more attention to the actual policies.

But then I started thinking would a lot of people just not bother?

For some people, voting is also about picking a side. If you take away the candidates and the party identity, does some of the motivation disappear too?

And there's another problem. What if someone just lies about their positions? You could end up making people vote more thoughtfully without actually making elections better.

Would you support trying this for one election just to see what happens?

I keep seeing women get mocked for liking things that are popular.

Stanley cups. Sephora. Uggs. Cute home decor. Matching workout sets. Certain coffee shops. Whatever the current thing happens to be.

And somehow, liking something that a lot of other women also like becomes evidence that you have no personality.

If a woman buys something because she saw it online, people call her brainwashed by advertising.

If she likes something because her friends like it, she's just following the crowd.

If she gets excited about a new product, she's “basic.”

At some point, I think we're reading way too much into someone's taste.

People like familiar things. People like trends. People like cute stuff. People like buying things that make them feel good. None of that automatically says anything about their intelligence or personality.

And yes, overconsumption is worth talking about. But you can talk about that without turning someone's interests into a judgment about who they are.

A woman liking a popular water bottle doesn't mean she's shallow.

Liking the same makeup brand as everyone else doesn't mean she can't think for herself.

Sometimes she just likes the thing.

“I liked it” should be enough.

I get that a check needs to be verified, but I’m curious what actually happens during those extra days.

If the check is deposited electronically, where is the money during that time?

And if banks can move other kinds of money almost instantly, why hasn’t that same process made checks effectively instant too?

Suppose a team of 1935 airline pilots gets one month in the full-motion simulator and cockpit of a 2026 airliner. After thirty days, they go back to their DC-2s and Ford Trimotors.

These pilots flew by needle, ball, and airspeed with a navigator and radio operator aboard. They understood weather, propellers, and radial engines at a deep level. Flying itself is not the mystery here.

But the jump is enormous.

Which part would unsettle them most: a cockpit with no steam gauges at all, an autopilot that flies the entire descent to minimums by itself, navigation precise to a few meters anywhere on Earth, or engines that manage themselves with no mixture levers?

Which of their 1935 skills would transfer perfectly, and which would they have to completely unlearn?

A lot of developed countries are facing problems because their populations are declining. We rely on a certain percentage of the population working, paying taxes, and supporting everyone else. When there aren't enough working-age people, everyone is worse off.

In the short run, there are plenty of things governments can do to increase population. They can encourage people to have more children, bring in more immigrants, or change policies around families and childcare.

But those things don't address the bigger problem.

Population growth cannot continue forever. There is some maximum population that the earth can comfortably support. I don't know whether that number is 10 billion, 10 trillion, or something else, and I don't know when we'll reach it. I just know that an economic system based on permanent population growth cannot be sustainable forever.

There are also plenty of things that could improve as birth rates decline.

Teacher to student ratios could improve. Housing could become less scarce. Unemployed people could have an easier time finding work. Per capita access to food and water could increase. Carbon emissions could decrease. More resources could go toward improving existing infrastructure instead of constantly expanding it to accommodate more people.

Obviously, population decline creates real problems too. An aging population puts pressure on pensions, healthcare, and the people who are still working.

But I don't think the answer should simply be making sure there are always enough young people to keep the current system running.

At some point, population growth is going to stop. Before that happens, we should figure out how to run an economy without depending on it.

I don't know what the solution is. Maybe whoever figures it out really does deserve a Nobel Prize in economics.

We just need to get to a point where a falling birth rate isn't treated as an economic disaster.

Standing looks effortless because there is very little visible movement. So why do our legs sometimes ache more from standing still than from walking around?

Anyone who has worked a retail shift, waited in a long line, or stood through a concert has probably felt this. Your legs are not moving much, but they are definitely working.

What is actually happening inside the body when we stand still that makes it so tiring?

The more I watch American politics, the more it feels like we are constantly fighting each other while ignoring the people with the most power.

I used to think the biggest divide was between Republicans and Democrats. But I started noticing that many ordinary Americans on both sides are dealing with the same problems: rising housing costs, expensive healthcare, stagnant wages, and a feeling that the system is not working for them.

I think the left vs right fight has become a distraction. A working class Republican and a working class Democrat may disagree on cultural issues, but they often have more in common with each other than with billionaires, corporate leaders, and political insiders who can influence the system.

The people at the top do not need Americans to agree. They only need us to stay divided and angry at each other.

I know this might oversimplify things. Not every political conflict is just about wealth and power.

But I keep asking myself why we spend so much time fighting people who are struggling like us instead of questioning those who have the most influence.

What would happen if more Americans started asking “who benefits from this system?” instead of only asking “are they left or right?”

For decades, 26 weeks has been the standard maximum for regular unemployment benefits in most states. But why 26?

Was it ever based on data about how long people typically remain unemployed, or did it emerge from the historical development of the unemployment insurance system? Why 13 weeks or 52 weeks instead?

During the Great Recession, temporary federal programs pushed benefits as high as 99 weeks in some high-unemployment states. What made much longer benefit periods appropriate then, but not in normal times?

Just curious where the 26-week standard actually came from.
