If an American moves to Europe and doesn’t attempt to learn the local language, then by a few months to a year in with zero effort people will say they’re in the wrong for not making an effort to integrate and expecting everyone to speak English for them.
My American cousin lived and worked in France as an engineer for several years. This is absolutely not true. He did make an effort to learn some French, but it wasn’t because of any pressure. He just wanted to.

If you stick to the premise that the portals exist in a universe with GR, then we can pay much know that space-time is locally flat in and around at least the middle parts of the portal. We know this because things don’t get fucked up when they’re going through.

It kind of is the wild west. In some cases, I think the track infrastructure is still exactly the same as it was from the old West days. There are some really breathtaking railroad bridges to go over, but they’re also limited to 15 mph because they’re so old. West Texas still has many miles of completely un-signaled “dark territory”.
This line traverses the Gadsden Purchase, a big chunk of Arizona that the US had to buy from Mexico in order to build this railroad. Back in 1854.

The service only operates 3 days per week. That’s 6 trains per week, total. 3 in each direction.
- Comment on America and it's racism and Israel? 2 weeks ago:
To be more specific, there’s a strain of white Christian nationalists that believe the book of Revelation predicts that Jews will rebuild a third temple on the Temple Mount site and resume animal sacrifice before the rapture or any other end-of-days event can occur.
To these people, activities that make that outcome more likely are laudable expressions of faith. There’s even a group that is trying to breed a perfectly red heifer in Texas, because apparently you need to sacrifice a perfectly ritually “clean” and unblemished red heifer in order to properly kick off a new temple.
- Comment on I say this as an ex-coder, but is it possible to ask for a paper ballot instead of using the stupid machines when voting? 2 weeks ago:
This is the case in nearly every state in the USA that uses machines. The big exception is Louisiana.
- Comment on What is negative voltage? 2 weeks ago:
The lowest geographic place in the United States is Badwater Basin in Death Valley. It’s altitude is -282 feet. That’s a negative altitude.
What does that mean? It means that Badwater Basin is below the 0 altitude level, which we have chosen to define as “mean sea level.” We could have chosen a different altitude too be zero, but we didn’t.
If there is a pathway from the sea (at Mean Sea Level) to Badwater Basin, then the water will flow to the basin, because it would have a lower potential energy in the basin.
Voltage is potential difference. It is always the difference in potential between two different points. But like altitude, we often don’t say one of the two points out loud because it’s a common reference level.
A positive charge in a vacuum will gain speed (kinetic energy) moving from a higher potential to a lower potential, because its potential energy goes down. It doesn’t matter whether it’s going from +9V to +5V versus 0V to -4V. The change in potential is the same.

- Comment on They don't cover nuclear war? Pass. 3 weeks ago:
Just like how Java is “not intended for use in a nuclear facility.” They put it in the long-ass click through agreement, so it’s legally binding.

- Comment on Since light cannot pass through a black hole does that mean light has mass? Also why does light form a singularity in a black hole? Is that like a fixed point on a map or something? 4 weeks ago:
Adding on to this…
The “rest mass” is so important to physicists because it is an invariant quantity under relativistic transformations. Think about kinetic energy. Kinetic energy is a form of energy, and therefore a form of mass. But different observers at different velocities can look at the same object and come up with different kinetic energies for it. But “rest mass,” the mass it would have at rest, is something everyone can agree on.
Finally, as the battery on the scale example demonstrates, photons make their own gravitational field from their energy. Since photons make gravity, they can (theoretically) make black holes. "Kugelblitz" is the name for a black hole that has been composed of only photons.

would require so much energy that it is (for now(?)) impossible to achieve.
It’s not just excessive quantities of regular energy. These schemes all require negative mass-energy or other exotic forms of energy. We have no theory of physics that predicts the existence of these forms of energy, and we don’t know how they would work.
Physicists who write papers about these things use neutral, professional language, like “exotic matter,” to describe this stuff, but it’s really pretty firmly in the realm of magical make believe.

I don’t know anything about it, but it seems like this game might not be equipped with BFG 9000.

Except the hazard is coming from the park service Barneys and not from the green water. Don’t panic. HEV Mark IV can handle this.

According to this, the charge is vandalism in DC Superior Court. That would be a misdemeanor, carrying less than 1 year in prison.
I wasn’t able to find a case entry in DC Superior Court’s docket system.

In this specific case, your phone exchanges radio signals with a cell tower, and then the cell tower transfers your data requests onto the wires.

Okay. But did it have one of those steam whistles, like on the old railroad? I feel like it would have done better on the market with a nice choo choo.
- Comment on 2 months ago:
Well see, they do actually have a list that says what everything costs. It’s called the Charge Master List. They just don’t want you to see that list, because they think it puts you at a negotiating disadvantage. It’s the magic invisible hand of the free market, at work to make pricing information available to all in the most efficient manner. (/s)

On the US census, “hispanic” is not a race; it’s an “ethnicity”. So your daughter will be faced with the choice of selecting a “race” and then also choosing “hispanic” or “non-hispanic.” Many other surveys use the same scheme.
How your daughter makes these decisions is up to her. As a social construct, race is what we humans make of it. 100 years ago, Irish and Italians were often not “white.”

It changed a lot. Even if you ignore the stuff that happened between the king and the emperor, that emperor changed a lot. Massive legal reforms. Upended world order. Etc. Etc.

Well, for one more moment anyway.
- Comment on Teachers deserve more money. 2 months ago:
There is no reason to have 50 separate curriculums. The ONLY reason that exists is so MAGA states can use the schools to indoctrinate American schoolchildren
That’s not the only reason. There are in fact principles of federalism, and there’s the 10th amendment to the constitution. Educating the public is not one of the 17 enumerated powers granted to Congress in article I. Under the 10th, powers that are not granted to the national government are reserved to the states or to the people.
This is why the national government’s regulation of education is based around carrots in the form of block grants that states apply for. Not enforcement sticks.

Apparently finalized a few days ago. But the news was published in The Onion, so you can be forgiven for thinking it might be satire.
- Comment on A long-ass way to write 'not parmesan'. 3 months ago:
That region of origin protection does not extend to the United States.
In the US, “parmesan” can legally be just about any kind of cheese made in any location (mostly Wisconsin), as long as it is aged at least 10 months, and not more than 32% moisture. “Parmigiano Reggiano” and some other specific trademarks are protected terms in the US that mean the same as they do in Europe.

- Comment on Land where 3 months ago:
The capsules can do a water splashdown with parachutes alone.
The capsules that land on land all seem to have some additional system to slow down in addition to the parachute. Boeing Starliner has airbags that deploy around and below the heat shield. Soyuz has a braking rocket system that fires immediately before impact.
- Comment on Wake up sheeple 3 months ago:
It was a three-barreled gun that fired shotgun shells, rifle rounds, and rescue flares. 10 rounds of each type of ammunition were supplied. The stock could be detached and used as a machete.
For a while, these guns were on every Soyuz capsule that docked with ISS, and they were under the operational control of the Soyuz commander. I’ve read that they may have been retired in 2007 because Russia finally ran out of the very unique ammo.
