I remember watching a YT video by Cody'sLab about 'boiling water until it freezes' in a vacuum chamber a while ago. Here's the LINK to the video. So if you wanna know for sure, just get a vacuum chamber

All three phases are in equilibrium, and a tiny increase in pressure from that point would yield the lowest liquid water boiling to water vapor.
In terms of feel, the water being boiled feels pretty cold. We're also on the order of 1/100th of sea level atmospheric pressure and well below the pressure where you would die from hypoxia w/ pure O2. So what does that translate to in a real life experience? If you stand on the Mount Everest for example? Water would boil at 50°ish (325 K)? Simberto's got the right way to use the phase diagram to find the lower boiling points at pressures far from those found around sea level.

This is really interesting!
This also means when you are in a submarine in a deep dive, water takes forever to boil ^^

The air pressure inside a submarine should remain constant no matter how deep it dives, if you want the human occupants to remain alive.

You sure? I was just thinking it would take a load of the hull if the inside pressure was higher than normal atmosphere. And humans can actually take quite a lof of pressure (thinking of apnoe divers), problems occur only when the outside pressure is suddenly gone. But maybe I was just overthinking this ^^
EDIT: Googled some more. Apparently there is a space between the outer hull and the inner hull which is pressured to take some off of the outer hull

Humans can take some pressure pretty well. If you don't breath under, you generally don't have a problem with pressures you can reach by diving without breathing.
If you breath under pressure, there are a bunch of different problems that can occur. If you spend enough time under pressure breathing normal air, (usually happens from about 3+ (20+ m below surface) atmospheres downwards for reasonable times spend below the surface), and surface too fast, you get problems because your blood is saturated with nitrogen at the higher pressure, which bubbles out at lower pressures. Which is something you really, really don't want to happen in your veins. This is called "decompression sickness" and is usually solved by simply ascending slower.
At even higher pressures (IIRC, 50+m), you have problems with nitrogen narcosis, because the partial pressure of the nitrogen is too high for you to handle. You solve this by having a different air mix, often exchanging the nitrogen in your air with helium (which is far more expensive).
Even further down, the oxygen in the air also becomes toxic to you. I don't exactly know how to solve this, but apparently it is possible. Probably even more helium and less oxygen in the air you breath?
Apparently the record for deep diving is 534m, with a specially designed air mixture.
You could build a submarine that pressurizes with the surroundings, but you would need to take all of the same precautions as commercial divers. This is problematic, because those limitations would severely hamper the function of a submarine. If you can only ascend at very low speeds due to avoiding decompression sickness (we are talking about possibly taking days to ascend if you have spent a long-ish time at low depths), and you surely don't want to deal with having a special air mix and all the logistic problems that leads to.

So I just found out TL.net and TeamLiquid are not the same thing but for the life of me I can't figure out how that makes sense. I have been on TL.net for over a decade and as far as I can tell the esports org definitely had something to do with this website. Is it just a coincidence they have the same name and logo?
Please help!

Team Liquid is the esports team that is sponsored by Tl.net AFAIK

Please help! They gave the teamliquid url to the pro team and moved the forum to tl.net.

Why is homelessness labeled as a housing issue https://endhomelessness.org/homelessness-in-america/what-causes-homelessness/housing/
The solution to homelessness is straightforward: housing. By connecting people experiencing homelessness to housing and services, they have a platform from which they can address other areas that may have contributed to their homelessness — such as employment, health, and substance abuse. when it is obviously a mental health issue? https://www.latimes.com/california/story/2019-10-07/homeless-population-mental-illness-disability
Mental illness, substance abuse and physical disabilities are much more pervasive in Los Angeles County’s homeless population than officials have previously reported, a Times analysis has found.
The Times examined more than 4,000 questionnaires taken as part of this year’s point-in-time count and found that about 76% of individuals living outside on the streets reported being, or were observed to be, affected by mental illness, substance abuse, poor health or a physical disability.. No mentally ill drug addict is going to have the capacity or resources to live in a housing complex under their own volition.

Which cane first, living on the streets from housing troubles, or the mental illness.
I’m super pissed that LA made perfect housing the enemy of housing projects for the homeless. In some council meeting, a man got up to protest money apportioned for homeless housing going to luxuries like granite countertops. A lady’s response was that they have a right to have granite countertops. Yes, welcome to Los Angeles.

Your source doesn’t say that 76% have mental health issues, it says that 76% reported meeting at least one of the listed criteria. You’re also confusing causation and correlation. You’re also ignoring examples such as San Francisco which show a very clear link between low housing supply (as expressed by high rent costs) and homelessness. If your hypothesis were true we’d expect them to be unrelated. You’re also ignoring that supplying the homeless with housing isn’t meant to solve all of their problems, it’s meant to address that they don’t have a home. It seems pretty evident to me that it would work at that. It’s like how food is a solution to hunger, it just is.

A lady’s response was that they have a right to have granite countertops. Yes, welcome to Los Angeles. We have common ground at last. Lack of a home is incredibly hard on people mentally, as well as preventing them from access to bank accounts, cell phones, mailing addresses, somewhere to bathe and wash clothes, or just anywhere to put their possessions so they don’t have to watch them constantly. The idea that people can simply reenter society without the basic foundation that a home provides is absurd, I’m not mentally ill but if you switched me with someone who was long term homeless I wouldn’t have a clue how to get shit unfucked. I know how to apply for a job but I don’t know how to get a state ID if I don’t have any proof of who I am on me and I’m not in public records in that state, it’s the foundation problems that you just don’t think about that would fuck me. After a while of that shit, plus crippling social rejection and isolation, escapism through drugs would probably seem a reasonable option.
The hypocrisy and NIMBYism of the response to homelessness is always frustrating. It’s the subset of Christians who have actually read the Bible who have the right idea about it. Treat your neighbours as people worthy of respect, empathy, and kindness. Feed them. Whatever you do for the least of these brothers of mine, you did it for me. The man was pretty explicit in his philosophy and it’s as true now as it was then.

I've asked this question some time ago in another thread, but didn't want to stray too far off topic. So I'm just gonna ask in here again, for further discussion: Why aren't kids taught how to raise (their future) children in school? I don't mean taking care of a baby, but actually raising and educating kids properly. It should be a mandatory class for everyone, raising the future of humanity seems like an important job, doesn't it? So why is "winging it" seen as an acceptable methodology, when it comes to parenting in our so called "modern" world?
|
Probably because people have very strong opinions on what constitutes proper parenting. Same way that teaching religion in public school would be fraught with controversy. I agree though that there should be guidance.
|
Also, because children in school would be utterly disinterested in that topic, as they see having children as a topic very far removed from their current reality. Ask anyone 10 years out of school how much they remember of a school topic they didn't like and didn't use at all since school.
A much better thing to do would be offering free parenting classes for couples once they are pregnant or plan on having children, as well as legally having time off of work for that. Also, if we are talking about the US, actual paid time off of work to be a parent.

I would have skipped that class every time

This would get tied up in politics so fast your head would spin. Sexual ethics is just the first problem, but move on to whether or not teaching a two-parent paradigm amounts to shaming single parents. Then teach division or portioning of household responsibilities. You start to realize why home ec classes shriveled and died.
Maybe winging it is a societal compromise with sexual liberty and rebellion against past patriarchal norms. Nobody tells you how to do things because that would “like be oppressive” at some level, and in return, you get ridiculous stress and catching-up with your first child. (I do however support a small number of dumb basics to be taught in a mandatory health class like vaccination, sex-ed including pregnancy. Also I support forcing ~17 year olds to literally carry around a fake baby for few days or week as means of broaching the topic of responsibility, as is the case in a number of school districts)

And what would that entail? What do YOU think such an education should be? Everyone has different opinions. Every family is different, even individual parents would have different opinions.
It wouldn't matter anyways. The vast majority of people don't care about raising and educating kids properly. They are far more interested in telling others about what a hard job raising kids are.
Anyhow, I often wonder why schools don't teach basic finance. Even something as basic as how to read a bank statement. How to balance income with expenditure. Interest rates. Pension plans. It's not like the economy will collapse from teaching that.
