.ml is the same way. People were getting deleted left and right for posting about Maduro fixing the election in Venezuela. Not realizing it’s freaking .ml. Even when told, “the mods are just enforcing the instance rules” they didn’t get it.
There’s a few mods that bans people just for being liberal there. What fucking clowns man. Then their little minions come to .world and whine about how they’re treated unfairly when they troll.
There are a lot of good answers here already, but I’ll try to attack the question from a new angle.
Firstly, yes: they experience an attractive force from the nucleus, and would in principle have their lowest possible potential energy if they were located exactly in the nucleus. An equilibrium state is the state with lowest energy, so why aren’t they exactly in the nucleus?
Consider that an electrons position and speed cannot be exactly defined at the same time (uncertainty principle). So an electron with an exact position could have any speed. If you compute the expectation value of a particles kinetic energy, when the particle can have any speed, you’ll find that it’s divergent (goes to infinity).
So: Because an electron with an exactly defined position must have infinite kinetic energy, the equilibrium state cannot be an electron with an exactly defined position, and so cannot be an electron exactly in the nucleus. So what do we do?
We have to make the electrons position “diffuse”. Of course, that means it is no longer exactly inside the nucleus, so it gains some potential energy, but on the other hand it can move more slowly and has lower kinetic energy.
The equilibrium state is the state we find where the trade off between kinetic and potential energy gives us the lowest total energy, which is described as a 1s orbital. The electron is “diffuse” enough to have a relatively low kinetic energy, and “localised” enough to have a relatively low potential energy, giving as low total energy as possible.
Once you start adding more electrons you need to start taking Pauli exclusion into account, so I won’t go there, but the same manner of thinking still essentially holds up.
Yes, there are an infinite number of velocities you can use, but if you look at their distribution, you’ll find that it quickly goes to zero somewhere around 1-2 m/s, so the expectation value of the velocity is convergent.
If you have an object with a velocity taken from a distribution that doesn’t approach zero sufficiently fast as the velocity goes to infinity, the expectation value diverges. A simple example would be a person that would be half as likely to get up at a velocity of 2 m/s as 1 m/s, and half as likely to get up at 4 m/s as 2 m/s, etc.
The more mathematical version of the same argument is to compute the kinetic energy of a particle whose wavefunction is a delta pulse (i.e. a particle whose position is exactly defined), and you’ll find that the particle has infinite energy.
I mean Dexter Holland has a PhD in molecular biology, but if you’re dropping into a half pipe you’re probably more likely to be listening to Smash than to his dissertation on tape…
Different contexts. She can run like stink (as in, fastest in the world), and I don’t see how that takes away from her academic achievements.
Maybe it’s just the handful of instances I follow, but I can’t recall anything. But I’ve become quite callused and thick skinned having Benn on the Internet sense the early 90’s and the wastelands of forums/chat rooms lol. Send help.
It’s probably because they can remember how convenient and cheaper it was to see any movie or show that could be streamed. Streaming was supposed to disrupt TV by eliminating ads and allowing you to choose whatever you want to watch. Nowadays, in order to get the same amount of choices, you need to spend about as much as you did for a TV subscription and now many platforms have ads.
I think it’s more a frustration at what we lost than anything else.
World is basically Reddit at this point, it’s where most of the big Reddit subs set up a Lemmy community, and is more or less the default option for someone setting up a Lemmy account for the first time.
did you follow the comments? cause I am calling out this person’s “typical redditor” behavior because of their elitism towards people moving over from there.
You still seem to misunderstand. I am not calling this person a redditor because I feel they are beneath me or something, I am calling them that because they talked shit, and used redditor as a pejorative, all while displaying the worst cliche behavior of the site.
The talk around weight loss is kinda crazy and a lot of it is dominated by pseudoscience.
However, we are pretty much positive that eating at a calorie deficit will result in weight loss in 99.9% of cases and you aren’t going to be the 0.1%. There’s a lot of anecdotal data about how eating too little will make you stop losing weight or even gain more weight because of your ‘metabolism’, but no controlled studies that show that to be a significant contributor without other causes. It’s not some magical metabolism trick, you’re just cheating on your metrics and doing less because you’re tired and cranky and have no energy because you aren’t eating right.
Saying that, eating at a massive deficit can definitely make you feel like shit and will make it hard to exercise, do not recommend. You will also likely have a part of your brain dedicated to fantasizing about food 24/7 and your libido will likely be in the trash if that matters to you. This will be very hard to maintain, and you have to remember that there’s never going to be a day where you can go back to eating like ‘normal’. Your current normal is why you need to lose weight and your goal is to eventually establish a new baseline.
Lastly, highly recommend against adding calories back due to exercise. We don’t have a lot of good data about there being any reliable indicators of actual calories burned available to the average person and you’ll find a tremendous amount of super variable answers when you find instances where people tried to actually test the estimates you see online. The time you put into exercise isn’t about weight loss, it will help, but it’s a bonus just for you because you deserve to have the body that you want.
I think this is just a bug because I have this issue with Safari where the only video options are 1080p or 360p, and for whtaever reason airplaying youtube videos has always been limited to 720p
I dunno. But if AirPlay works by sending your screen over wifi, it might be a bandwidth issue. Streaming video from youtube to your phone and then from your phone to a TV can be quite intensive, especially with modern phones being 1080p or more, which takes more bandwidth to stream to a TV. I’ve had this problem on a slow wifi on Android, and there’s not much you can do to fix it besides upgrading your router.
However, it doesn’t mean that’s exactly what is happening here. Certainly someone could be throttling video quality on purpose and we wouldn’t really have a way to prove it. With how shady and monopolistic big tech companies are, I wouldn’t put it past any of them (google and apple)
Can you imagine being stuck in the dawn of human agriculture, and you seek shelter in a nice cave that you found… And then a Giant Sloth just lumbers in after a bit.
I mean, I imagine any Homo species of the time would know not to go inside one of these, but still.
I hear what you’re saying, and I recognize anyone inside would be safe from being eaten… However, as with an elephant, I wouldn’t want to be woken up in the middle of the night having intruded upon their home.
nah they’d be chill. They’d be like “waaat” and make some initial annoyed sounds at first, but then once you pull out the bong they’d settle down and be chill.
