Yes. The fall of the Berlin Wall is one example.
I’ve asked this before but is there any historical event that is like the Opposite of 9/11. Like something so good that happened that it changed the world forever

Is that a good event or the end of something bad? If it counts, so does the end of a war. Maybe Yeltsin visiting a US supermarket would be better.

Not insane. This is the most basic and well-known covert channel. It has been exploited since at least the 1980s. It is super fast and super easy to implement. Anyone who puts any thought into covert channels assumes this exists.

Here is a very quick graphic I drew up to show the B-2 Spirit compared to common US media estimates for the B-21's wingspan, the smallest assessment I came across in Chinese media, and now the actual (estimated) dimensions thanks to @Aviation_Intel and @thewarzonewire based on Google Maps imagery.

Math isn’t my strong suit, but shrinking the B-2 by that much seems to shake out to a roughly 30% reduction in internal volume (not weight, but space for ordnance). Of course, a different payload bay layout and internal design could make those numbers nonsense anyway.

A better measure of payload is "wing" area and air speed. The max gross of an airplane is constrained by these two. Volume grows with the cube of span and lift/gross weight grows with the square. A 747 has a higher volume to max gross ratio than a 737.

Why is Germany's anti-immigration AfD surging in popularity? And why does immigration seem to work better in America than in Europe? A Bosnian refugee, turned American citizen, who now lives in Germany, joins us to explore Europe's immigration backlash: open.spotify.com/episode/38h…

Good conversation. I wonder if the labor and economic restrictions when the Turks came in the 1970s were looser than they are today. Coworkers and classmates are two of the biggest assimilation forces.

Is this a case of theory vs. practice? In practice, opaque bureaucracies assign your property value with little recourse to the homeowner. Overlapping school districts, transit areas, and municipalities set the rate. Small constituencies tack on bonds.

wyoming and colorado are made of 4 straight lines, but they still aren't rectangles. lines of longitude get closer as you go north, so the top edge is shorter than the bottom. for wyoming it's about 6% shorter

Also, except at the equator, longitudinal lines are not straight. North of the equator, driving due west requires a slow turn to the left. Even the equator is just a segment of a circle centered at the center of the Earth that requires constantly turning "downward".

Since the French don’t have guns, and the police won’t enforce order, maybe store owners can boobytrap their buildings so we can get more of this.

LLMs have become able to deliver more tokens with the same amount of hardware. There is competing hardware to the H100 that is also generating those tokens, while the H100 can be used for other uses (like training).

Apparently there's a Jones Act equivalent for cruise ships if they do strictly domestic stops, which is why all of them do an international stop even if it's basically a joke. That's why river cruises in the US are so expensive compared to oceanic ones.

Hawaii too. You either take the one old cruise ship, or you make a stop hundreds of miles away at someplace like French Polynesia.

They knew it was the SRB because thr live broadcasts showed the explosion starting at the SRB. They took time to figure out how it failed. However, anyone could see it was the SRB.

Maybe. If they do not get too hot, too wet, or get too high of voltage. Thermal cycles and moisture are really tough on electronics. High voltage may over drive them. 120 V from the socket can drift up and down.

Many people hope remote work will raise birth rates. No commute, more flexibility, a chance to live near family. I test the idea in a new paper. Among married women, the 2020 expansion of remote work reduced births. 🧵

Cool paper. However, their are a ton of variables that correlate with 2020 behavior and occupation: urban vs rural, political views, state of residence, etc. I see you tracked age.

Indian immigrants and their families have earned success despite being broadly discriminated against by US higher education. Envy explains the one-sided political backlash against them. Mercifully few Indian Americans are aware because they are working too hard to notice.
The most educated religious group in the United States is Hindus. By a long shot. 47% have a graduate degree. Jews are next at 39%. Then a big gap. Those least likely to have a grad degree? Jehovah's Witnesses.

On another note, I'm not sure I trust this survey. LDS look much less educated than I thought they'd be.

LDS members spend time doing mission work before starting college. That can bias the sample because they are not done with school as soon. Also, the mission work can expose them to life paths that do not include a bachelor's degree.

Not sure. Can Europe mimic the US’s success? Can the U.S.’s immigration turn into a European style, is immigration still a net good in a post-scarcity world, are there specific populations we shouldn’t attract as immigrants?

Europe and the US cannot both have successful immigration. It is a zero-sum game. People ambitious enough to move to a different country for economic opportunity are incredibly scarce. Even within the US, moving between states is rare.
