Ice is a solid, so adding salt to it cannot lower the freezing temperature of water, which is a liquid. The only way this can work is if the ice melts.

Why does ice melt when you put salt on it? Well, ice is already melting because, in this example with an ice cream machine, it is at room temperature. But by adding salt to it you are also adding weight, you are increasing the 'grain' of the mix, which becomes relevant as the machine spins, and grinds. This facilitates it melting faster.

It has nothing to do with lowering the freezing point as far as I can see. It does lower the freezing point, but the ice cream machine is operating at a temperature above freezing, and spinning (adding energy) which increases the temperature. The explanation is that it helps it melt faster, which then allows the coldness to transfer to the inner shell of the machine more efficiently.

Yes. You want money tied to the dollar? Keep your dollars.

Charter schools operate with public money and have to meet certain requirements, specified in the "charter" they sign with the government. However, they have a lot more freedom in how they operate than traditional public schools. This typically means that they use non-union teachers. They can often have different educational philosophies, with some being more strict (uniforms, lots of homework) and others being less strict (wholistic learning, no grades, etc.)

So the first benefit of charter schools is that they provide an alternative to traditional public schools. If a charter school is unique in a way that you or your child like, then it could be a good fit. The evidence on charter schools being all around "better" than traditional public schools is more mixed. Parents who send their children to public school consistently report being satisfied with their choice, but not all charter schools improve student achievement on things like standardized tests.

Assuming the consumer didn’t care at all, would it be possible to treat cows with hormones to keep them going without having to make a baby?

This is the first explanation I've read about this topic that made me understand it.

The robots we have at work had their code written by an integration company we use. The first 1-2 hundred lines of each program is "where to go next", with a bunch of

>if (all these conditions match) GOTO {section that handles whatever is supposed to happen next}

It's always a huge pain whenever I'm writing new code to add or improve functionality, and trying to check that I didn't introduce any new possible states where it can't figure out where to go - because I have to jump from line 50 to 400 to 30 to 670 to 30 to 900 etc.

Having the function directly follow the "if" condition seems like it would make more sense.

Question for you: if I want to improve my coding skills (because I only took one class in school, and have just picked other stuff up as I go), would it be a good exercise to re-write all their code using the structure you've outlined? And/or if I'm trying to learn another language like python specifically, see if I can re-write it in that, so I can learn that syntax & commands at the same time?

In COBOL the goto didn't even have to specify the destination. You could do an ALTER and have it go somewhere else. Try reading that.

GOTOs are bad but ALTER is Satanic.

This. I work at a public charter school and the main draw is that we aren't the huge, local high school. My largest class is 14. My school is on the campus of a local technical college and we offer dual enrollment courses as well. My state is not heavily into funding public charters (yet), so the principal definitely runs the school like a business. We get zero local tax dollars, so any funding we get is based on number of students. Having worked in private, large public, and now public charter.... School is school. There will be issues everywhere. Is it great that my current students have a free option for a more individualized education? Yeah, especially because many of them were planning to drop out. Are there benefits to a large school that we don't have? Yeah, I am a science teacher who has a TOTAL of 3 beakers. As a parent, pick what your kid needs. Leave the politics out of a major part of your kid's childhood and send them somewhere where they will learn to love reading, thinking, and learning.

Vermont as well was in theory its own country, but it wasn't recognized as a country by anyone and generally intended to join the US anyways (which it later did).

Had no idea that it was a racist or classist term. Just kept hearing the term a lot and never knew exactly what it meant. My bad

It's the market.

In *theory*, Tether is supposed to maintain a value of $1 USD because the issuing company (Tether Limited) says they maintain a reserve of $1 USD for every Tether.

However...Tether Limited doesn't actually do that. They're up to their eyeballs in lawsuits right now because they don't have the reserves the claim to and they won't let anyone audit them to figure out what they do have.

The problem is already so bad that elderly people have been found dead in their homes, and rotting there for weeks, even months. They have a word for it, kodokushi.

The issue Japan has is similar to other countries in that they’re not replacing current people with enough people to keep the country operational. On top of this, and in no way am I saying this as to imply racism on my part (I used to live in Japan and love their country), but their immigration laws are extremely strict with a layer of xenophobia. The #1 way countries have alleviated demographic challenges in the past are through immigration. The US has done this and still does. For example, we import many farm workers, low-wage industrial workers, and scientists, too. When a country refuses to accept outside help, problems arise.

Currently there are over 100 million forcibly displaced people on the planet, 89.3 displaced globally and 53.2 displaced internally within their home country. That’s 1% of the population, or 1 in 78 people, roughly.

What a deficit of working-age people will do to a country we can already see some of the effects of now. Labor shortages, sometimes severe, which leads to increasingly higher demands put into current workers. Services and goods are less available because production decreases. The quality of things decrease, like maintenance getting done. It takes longer to get things. Some businesses shut down because it becomes impractical to keep enterprises going. That’s a brief explanation what demographic imbalance looks like.

An example of a country that has perfect demographics is actually Mexico. They have the right number of old, working age, and young people.

Some charter schools are unionized, though many are not. Typically the draw of charter schools are that they are not the local public school. That is to say if a family lives somewhere where the public school is less than stellar, parents often choose charter schools as a “free” alternative to the public school. Some states have also invested heavily in charter schools, often to the detriment of public schools (see PA). This means charter schools have to compete for students, being run like businesses with marketing teams and multiple locations.

In case it are not clear what me are talking about. Why does us decided that the top one are right, while the lower one are wrong.[punctuation sic]

Get it? Yes, we've just gradually agreed on a way to communicate. Math is just language.

If you check out NFACC guidelines, atleast in North America, the “lack of space” housing such as crates has been completely phased out. All veal farms I’ve visited (Canadian) group house calves in large pens and provide both natural and artificial lighting and enrichment such a toys and brushes.

Some babies still receive morphine or methadone if their neonatal abstinence syndrome is severe enough.

Did this convention come about before or after the usage of parenthesis in mathematical notation? It seems like they cover the ambiguity problem pretty well.

No. Also charter schools are less restricted in what teachers they can hire. Most in my area are specifically religious.

Charter schools aren't unionized. They operate like private schools, except that they are publicly funded.

This gives the schools more freedom, but you may get a lot of younger teachers who didn't obtain a union job and will leave as soon as they do obtain a union job. The same is true of private schools, though.

The quality of student at a charter school may be better simply because of the hoops parents and students have to go through to attend a charter school. And the school may have more freedom to expel troublesome students.

As with any school, research the options because the quality can vary a lot.

When my brother’s son was born, the doctors told him that his son had been born with a dependence on crack. Immediately my brother was scared, as he didn’t understand what that meant for his newborn. The doctors informed him that the baby had been exposed to crack in the womb and that his system was not ready to handle being without the drug. The doctors then explained that the baby would need to undergo a process to detox from the crack and would need to be given small doses of medications to help the baby ease off of the drug over a period of time. My brother was relieved to know that his son would be monitored carefully and would undergo an appropriate treatment plan to safely get him off of the crack for good.

The sound rom the engines should I think not change from the time the vehicle goes supersonic up to engine cutoff, since from that point on, the only sound from the engines that can reach the crew is that which is transmitted through the vehicle structure.

Aerodynamic noise from the air flowing around the vehicle (though I don't know how audible that would be with the smooth aerodynamics around an ascending rocket) would of course steadily dimish during ascent.

Are charter school teachers in the Union?
