air displaced from the point you teleport to is instantly moved to form a monolayer (1 molecule thick) on your surface.
The displacement of air is adiabatic (no heat is transferred, which will be true if the displacement is instantaneous)
Volume of displaced air: ≈ 100L = 0.1m^3 At atmospheric conditions: ≈ 4 mol
Surface area of cylindrical human: ≈ 1.58 m^2 Diameter of nitrogen molecule (which is roughly the same as for an oxygen molecule) : ≈ 3 Å Volume of monolayer: ≈ 4.7e-10 m^3
Treating the air as an ideal gas (terrible approximation for this process) gives us a post-compression pressure of ≈ 45 PPa (you read that right: Peta-pascal) or 450 Gbar, and a temperature of roughly 650 000 K.
These conditions are definitely in the range where fusion might be possible (see: solar conditions). So to the people saying you are only “trying to science”, I would say I agree with your initial assessment.
I’m on my phone now, but I can run the numbers using something more accurate than ideal gas when I get my computer. However, this is so extreme that I don’t really think it will change anything.
Edit: We’ll just look at how densely packed the monolayer is. Our cylindrical person has an area of 1.58 m^2, which, assuming an optimally packed monolayer gives us about 48 micro Å^2 per particle, or an average inter-particle distance of about 3.9 milli Å. For reference, that means the average distance between molecules is about 0.1 % of the diameter of the molecules (roughly 3 Å) I think we can safely say that fusion is a possible or even likely outcome of this procedure.
To be fair, the result of this calculation only depends on the area/volume ratio of the human. I used the specific cylinder, because humans are roughly cylindrical, and have a volume of roughly 100 L. The surface area of a regular human is probably a bit larger than that of a cylindrical one though.
To be fair: If you live in the south, it doesn’t make much sense, but if you live a bit further north it’s the difference between getting up when the sun is a a reasonable place, or getting up in the middle of the night (winter) or the middle of the day (summer). I want it to be light out when I’m awake, not when it’s sleeping time.
Turns out it’s easier to adjust the clock than to say “work starts at 9 in the winter and at 8 in the summer”
Some languages - specifically Norwegian that I know of, don’t have separate words for “boyfriend” and “girlfriend”. In Norwegian we have the word “kjæreste” which can be directly translated to “dearest”. To me it always feels a little weird to use “boyfriend” or “girlfriend”, i guess the same could be true for other non-native english speakers.
It just really rubs me the wrong way when people want to “rewrite history” either by modifying books, art or anything else, to fit their modern world view.
First of all: I think it’s naive to believe that we somehow now have “the answer” to what is “correct”. Secondly: I really don’t like setting a precedent that we can just erase uncomfortable things at any time. Imagine the how much has been lost throughout history by different cultures erasing things they didn’t like.
Most of all, it’s the concept of judging acts or words from other times and cultures based on our idea of right and wrong that just gives me the impression that people lack perspective, and the ability to put things into context.
According to information from its own sources reported by German t-online, based on reports from circles within the Social Democratic Party, the German government intends to announce the supply of Taurus missiles to Ukraine “in the near future,” the publication states.
Investor confidence in China’s troubled property sector has been rocked again this week by reports that one of the country’s largest private building conglomerates missed interest payments on two bonds.
A candidate in Ecuador’s upcoming presidential election, Fernando Villavicencio, was assassinated at a campaign event in the capital Wednesday as a deadly escalation of violence and crime grips the South American country.
It breaks my heart to see people that are trying to good get hurt or killed by those only trying to turn a profit. I have to wonder, at what point to enough people become so sick of the violence that follows cartels like this that you start getting significant peoples militias set up to protect local communities?
To me, it seems objectively easier to pull into a parking space forward and then back out of the space when you are ready to leave. You don’t have to line up with the lines while driving backwards, and it’s easier to keep from hitting other cars as well. So why back in? To me, the only advantage I can think of is that you...
There’s a comment on another post with this article doing the math on this, and it seems like the net emissions (when you account for efficiencies) actually favour steam-reforming + fuel cells.
One of the advantages of hydrogen is that tanks and fuel cells can withstand a large number of “charging cycles” much better than batteries. Additionally, for ships, the amount of energy needed to move is so enormous that I fear we’ll have a hard time creating batteries that are feasible for long-distance shipping.
For short distance ferrying (including large, car carrying ferries) on the other hand, Norway has already implemented quite a few electric stretches. The major issue there is building the infrastructure to charge the ferries.
If we’re able to make hydrocarbon-synthesis from CO2 efficient… we’re still going to need to source the hydrogen somewhere.
But if we do that using electrolysis (with renewables), and are able to create more energy efficient CO2 capturing processes, I could see synthetic hydrocarbons as a viable fuel option in the future. The thing is: They’re stupidly good at being stable, energy dense, energy carriers. We also have a lot of infrastructure in place to handle hydrocarbons already.
In principle, synthetic hydrocarbons could be part of a zero-emission cycle, where we capture CO2 and electrolyse hydrogen with renewable energy, and use the hydrocarbons as an energy carrier. But if we go that way, we’re definitely going to have to research efficient hydrogen production, and probably storage as well.
I think “dropping like flies” is a bit of an overstatement when you regard the number of sorties being flown. I think this is more a sign of how saturated the airspace is with AA, if any pilot is just a bit uncareful or unlucky, they will get shot down.
Tbf. these have been more effective than I would have liked to see against Ukrainian armour, and we even have a video of one surviving having its tail shot off.
As for how they would do if western aircraft were in the air: That might be a different story, and not one I’m going to speculate about.
I’ve seen reference to research showing pretty much what you’re saying: Inadequate pay gives dissatisfied employees, but raising pay above a certain level only gives very short term increase in employee satisfaction. The conclusion was that pay has to be high enough that people feel fairly compensated, but further increasing it has little to no long-term effect.
I’ve thought about this regarding code as well: An AI is nothing without a training data set, if someone uses licensed code to train an AI, they should definitely be bound by the license. For example: If an AI is trained using copyleft licensed code, the resulting model should also be regarded as copyleft bound. As of now, I suspect this is to a very large degree being ignored.
Of course, once the AI is trained, you can’t look at some arbitrary output and determine whether that specific output came due to some specific training data set. In principle, if some of your training data is found to violate copyrights you either have to compensate the copyright holder or re-train the model without that data set.
Finding out whether a copyrighted work is part of the training data is a matter of going through it, and should be the responsibility of the people training the model. I would like to see a case where it has been shown that a copyrighted dataset has been used to train a model, and those violating the copyright by doing so are held responsible.

I know this is typical for the US so this is more for US people to respond to. I wouldn’t say that it is the best system for work, just wondering about the disconnect.
Yes, but also: In a lot of professions you have a lot of freedom regarding when you work. I’m browsing lemmy now, and getting to work at around 10, but I worked late on Friday, and I’m probably going to be answering some mails after dinner today.
I think this is just going to become more common: Not paying people for for the time they are at work, but rather for the job they do. That means that if you prefer to work 9-5, thats fine, but if you prefer to leave earlier or start later, and get some of your work done in the afternoon/weekends, thats also fine, as long as you get the job done.
I very much enjoy having that freedom. Even though it means I may be expected to pull longer days every now and then, it also means nobody questions me for leaving early when the weather is nice.
The thing about university “requiring” people to work more than 8 hours is this: It’s not a human right to become a system architect, physicist or engineer. Universities typically don’t require more than 8 hours per day, but a lot of studies in practice require more than 8 hours if you want to be able to get through them. Relaxing the requirements for passing a degree would mean less competent professionals leaving the universities, and I don’t think anyone getting on a plane or going into surgery wants that.
The thing is this: You wouldn’t have known what kind of activities you enjoy unless you had been exposed to a variety of them at some point. I absolutely think part of the education system’s job is to expose kids to a wide variety of activities, help them push their boundaries regarding what they think is fun, and experience mastering different things.
I don’t know about your education system, but it seems like there may be a too one-sided focus on some sports. I remember from my time in grade school that we were exposed to pretty much everything from hockey/football (the kind you play with your feet)/basketball to dance/gymnastics/weight lifting/track and field, etc.
I remember back in the day when people would “Jailbreak” iPhones, but never really picked up on what they were doing other than that it let them do stuff that those of us with “non-jailbroken” iPhones couldn’t do....
Ahh, that makes sense. How did you go about doing that? It’s not like you have a terminal to mess around in on an iPhone? Is the reason I haven’t heard of it in a while that it’s harder/impossible in newer iPhones?
Also: Why would apple prevent you from having root access? The way I see it, when I buy a phone, just like a pc, I should be allowed to do what I want with it.
I can definitely see them leaving macOS alone though. I can’t imagine anyone would buy a macbook to use for development if they don’t have root access, while, as far as I know, nobody buys iPhones or iPads to develop anything. If they do it would only be for testing purposes, which I assume should be fine without root access, as you’re developing for an end-user that doesn’t have root access.
They also started actively working to stop folks jailbreaking. That part, I thought, was too much. Just tell them they void the warranty by jailbreaking and refuse support.
I think it’s fair to void support for someone that goes ham in the terminal and breaks a bunch of shit, at least if you explicitly state that doing so will void support. You have root access on your macbook, but I assume the average person using it knows more about what they’re doing than the average person jailbreaking their phone (which was pretty much anyone as far as I can remember). Also: If you tell support that you opened the terminal and typed a bunch of stuff and now your macbook is broken, I assume support is likely to tell you “tough luck…”
In Norway we have the stereotypical Norwegians “Ola Nordmann” and “Kari Nordmann”. Ola and Kari were quite common names a couple generations ago (not so common now). “Nordmann” literally translates to “Norwegian [person]”, but is also a not-too-uncommon last name.
We typically talk about them if we’re describing something or some situation and what the stereotypical Norwegian would do/think.
I mean, if today i.e. is Sunday then someone long time ago should have said “Today will be Sunday” for the first time in a period from today that is multiple of seven.

Don’t know about Saturday, but “lørdag” comes from the Norse word for “washing day” because the vikings were surprisingly hygienic for their time, and bathed/washed themselves once a week.
I can’t help but point out that smartphones (with the apps typically found on them) are essentially on-demand dopamine devices. Pretty much any game or social media app you can install has as its primary goal to get you addicted. That’s their business model.
Very little can hope to compete for a child’s attention against such a device. In fact, I think even the fact that we are allowing children to be exposed to this when pretty much everyone agrees that they should be protected from drugs (alcohol, nicotine, etc. included) is kind of crazy.
Kittens typically aren’t given away before they are a couple months old, so they most probably met each other.
Either way: I’ve seen this in action. We had a cat that had kittens, and we were unable to give away one of them. When the kitten started growing up the mother started harassing it, eventually to the point of chasing it off. Luckily we found out that it moved in with some people a couple streets over that were very happy to have it. The point is: Cats aren’t pack animals, and typically don’t like sharing their territory with other cats, even if they are related.
Normally the mom cat would tell her kids to move out after a few months.
Exactly this, we had a cat that did this that I mentioned in another comment. It was quite brutal to watch, as we happily would have kept both mother and child, but cats don’t work like that.

Great answer! I’m just commenting because I think this would be a question that would be nice to post on c/askscience where I regularly lurk and look for cool questions to answer, but where there aren’t too many questions being asked yet :)

I do what I can to prevent the worst case scenario, but when anyone asks how I think this is going to go, I always answer “I objectively think we are all going to burn and die, but I’m not going down without a fight.” That’s all it is. I don’t think we are going to save the world, but I want to go down swinging.
I’m one of the people that thinks the world is probably going to shit (mass migration from uninhabitable land, wars over water / farmland etc.) but I don’t use that as an excuse to not do anything. My reasoning is that even though I honestly think everything is going to shit, I might be wrong, so the best I can do is plan to go down fighting to make the world better. Either the world burns, and I can say with integrity that I tried my best, or we somehow pull through and prevent the worst prognosis from becoming reality. Either way, slacking is a bad idea.
I agree that the characters weren’t the most engaging, but to me the engaging part of the story was the description of the society itself. The characters were only there to give the reader a perspective to view the world from.
