• ⁨Comment⁩ on ⁨What's it going to take to truly stop the US?⁩ ⁨⁨20⁩ ⁨hours⁩ ago⁩:

  Obvious answer is that the USA is the world’s largest economy while Russia is not, so if USA says “if you trade with Russia then you can’t trade with me” then most countries will happily accept ceasing trade with Russia to remain in the US market but if Russia says the same about the USA then people would just laugh and go trade with the USA.

  The only country that might have some leverage in sanctioning the US is China but China has historically had a “no allies” policy. Chinese leadership hate the idea of that because then they would feel obligated to defend them and defending another country is viewed very poorly in Chinese politics. They thus only ever form trade relations and never alliances, meaning if your country is attacked they have no obligation to you. Chinese politicians may verbally condemn the attack but they won’t do anything like sanctions or even provide their own military support in return.

  Trying to think of classical models to explain the EPR paradox kinda misses the point of the EPR paradox, because the point of the EPR paradox is to assume that there is indeed nothing linking the two particles until you look to then show you that this leads to a contradiction with Einstein’s definition of locality.† You can indeed trivially think of classical explanations to explain the EPR paradox and how the +1 and -1 particles might be linked and predetermined, but that’s not the point of the EPR paper which is to explore what happens if we don’t make this assumption.

  The paper that instead explores what happens if we do assume they are predetermined is Bell’s theorem, and Bell’s theorem is more complicated than just assuming that the particles are entangled and opposites such that one will be measured to be +1 and the other to be -1. Bell’s theorem shows that the behavior of the individual particle can be dependent upon the configuration of a collection of measurement devices, even if the particle only ever interacts with one measurement device in the collection. That not only violates Einstein’s definition of locality, but if you try to make it deterministic, it ends up violating special relativity as well.

  The simplest demonstration of this is with three particles in the GHZ experiment. The point is, again, not merely that the particles have correlated values but that (1) those values are statistically dependent upon the configuration of the measurement device and (2) the values for an individual particle can be statistically dependent upon the configuration of a collection of measurement devices even if it never interacts with most of the devices in the collection.

  † “Locality” is used in two different senses in the literature. One is relativistic locality which means nothing can travel faster than light. The other is what I like to call coordinate locality which is what Einstein had in mind with the EPR paper, which is the idea that things have to locally interact to become dependent upon one another. The EPR paper is a proof by contradiction that quantum mechanics without hidden variables violates coordinate locality specifically.

  In Copenhagen, “observing” really does just mean “observing” in the colloquial sense, there isn’t a fancy scientific meaning for it as the “collapse” is treated as a subjective update of knowledge and not a physical event.

  Banks aren’t that strict about super high credit scores. You can have a low score and they’d still give you a loan as long as it’s not absurdly low and you don’t have a bunch of other outstanding loans and you have an income. At least in my experience, my “credit” was basically one credit card I owned for a year and the bank still gave me a loan for a house. I would not bother to stress too much about the specific number. If your credit score is so low you won’t be able to secure a loan, you’d probably know without looking anyways. Just make sure you at least have one credit card because otherwise you might not have any credit at all which can make it hard to secure a loan.

  A double-standard is not inherently a bad thing. It’s a double-standard that we allow trained and licensed medical doctors to do operations on people but not bozos without any medical background, but one would have to be an imbecile to say this double-standard is a bad thing. It is indeed a double-standard to not show empathy to people who support industrial scale genocide to themselves be merked while believing we should show empathy to the victims and to people who do not advocate for such things when they die, but it is a good double-standard. It’s completely ridiculous to think we should be applying a single universal standard to everyone because people are not all the same.

  Bullet-proof vest wouldn’t have saved him as he was sniped in the neck. The head is a moving target and harder to hit, which is why the less professional sniper missed Trump, he tried to shoot him in the head and Trump happened to move his head at that very second, and aiming for center of mass can be risky in case they are wearing something bullet proof. The neck is clearly exposed and more stable of a target than the head. The sniper knew what they were doing.

• ⁨Comment⁩ on ⁨observes your slit⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  The interference pattern disappears if anything becomes entangled with the which-way information at all. You can replace the entire measurement device with a single particle that interacts with the particles at the slits in such a way that it becomes perfectly correlated with the which-way information that the observer has no awareness of (such as if a moat of dust interacts with the particle because the experimenter did not isolate it well) and that is sufficient for the interference pattern to disappear.

• ⁨Comment⁩ on ⁨Too soon?⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  It comes across to me as they simply lack empathy for other “kinds” of people. If you actually felt the same pain and empathy when watching the video of Kirk get merked, you should feel that a thousand times over when seeing a thousand videos of the IOF massacring children, many sniped in the same way Kirk got merked, and then you should look upon Kirk in disgust for supporting that and dehumanizing the Palestinian people. But the fact is these people don’t. They don’t see other “kinds” of people different from them as in fact “people.” Let’s be real, they don’t feel the same kind of empathy for Palestinian fathers dying as they do a white fascist dying. They constantly mock the deaths of minority groups like trans people. They suddenly have empathy and demand pacifism and valuing the sanctity of all life when a white fascist dies, but are silent in every other cas.e

• ⁨Comment⁩ on ⁨observes your slit⁩ ⁨⁨3⁩ ⁨months⁩ ago⁩:

  They don’t even explain it in physics class. That is kind of the schtick of the Copenhagen interpretation. You just assume as a postulate that systems are in classical states when you look at them and in quantum states when you do not, and from those two assumptions you can prove using Gleason’s theorem that the only possible way the former can map onto the latter is through the Born rule. But there is no explanation given at all as to how or when or by what mechanism this transition actually takes place.

  Many Worlds isn’t much better because they posit that the classical world does not even exist, yet that clearly contradicts with what we directly observe in experiments, so if that is true it necessarily means that the classical world is an illusion, and so then you still have to explain how the illusion comes about, which they do not. Dropping the postulate that there is indeed a classical world also disallows you from deriving the Born rule through Gleason’s theorem, and so it then becomes unclear how to do it at all without some arbitrary additional postulate, and the arbitrary nature of it means there are dozens of proposals of different postulates and no way to decide between them.

  Modern physics is of the form (1) there is a classical state, (2) you look at it, (3) a miracle happens, (4) you perceive a quantum state, and then you are repeatedly gaslit into believing quantum mechanics is a complete theory of nature and it’s impossible for there to ever be anything more fundamental than it and any physicist who thinks there might be, even if they are literally Albert Einstein, is a crank crackpot.

  They are NOT looking to see if you are responsible with money. They are looking to see if they can make money off of you, so they want you to be a heavy credit user. Before I bought my house I made sure to take out two credit cards and just buy random shit on them for a few months because that boosts my credit score drastically which then made it easy to get the loan.

  i use one of those trackball mice with the ball on top. first time i tried it i never went back, no need to worry about having a proper surface or desk space for a mouse ever again. if you reach the side of your desk using an optical mouse, you have to pick the mouse up and move it all the way to the other side of the desk, while is a proper ball mouse (a good one without too much resistance) when you flick the ball it can continue spinning a bit even as you release it, so you can flick it to the side and then bend your wrist slightly to then flick it again, and the mouse cursor will just continue moving without stopping, which in games you can do this to have endless turning around, when turning is always stuttery on an optical mouse due to hitting the end of the desk. it takes a little bit to get used to, but at least a good one with limited resistance and a large ball, you can easily get just as accurate as an optical mouse as well. the only downside i find is that i do have to take the trackball out and clean it like the ones on the bottom.

While people do say maybe he just changed his clothes, the problem is if he also changed his backpack, he couldn’t have just put the clothes in the backpack, meaning he would’ve had to have left them somewhere and there would’ve been a trail that probably would’ve been found by now.

  It’s always funny seeing arguments like this as someone with a computer science education. A lot of people act like you can’t have anything complex unless some intelligent being deterministically writes a lot of if-else statements to implement it, which requires them to know and understand in detail what they are implementing at every step.

  But what people don’t realize is that this is not how it works at all, there are many problems that are just impractical to actually “know” how to solve yet we solve them all the time, such as voice recognition. Nobody in human history has ever written a bunch of if-else statements to be able to accurately translate someone’s voice to text, because it’s too complicated of a problem, no one on earth knows how it works.

  Yet, of course, your phone can do voice recognition just fine. That is because you can put together a generic class of algorithms which find solutions to problems on their own, without you even understanding the problem. These algorithms are known as metaheuristics. Metaheuristics fundamentally cannot be deterministic, they require random noise to work properly, because something that is deterministic will always greedily go in the direction of a more correct solution, and will never explore more incorrect solutions, whereby an even better solution may be beyond the horizon of many incorrect ones. Technically speaking, we would say they get stuck in a local minimum.

  A simple example of a metaheuristic is that of annealing. If you want to strengthen a sword, you can heat up the metal really hot and let it slowly cool. While it’s really hot, the atoms in the sword will randomly explore different configurations, and as it cools, they will explore less and less, and the overall process leads them to finding rather optimal configurations that strengthen the crystaline structure of the metal.

  This simple process can actually be applied generally to solve pretty much any problem. For example, if you are trying to figure out the optimal route to deliver packages, you can simulate this annealing process but rather than atoms searching for an optimal crystaline structure, you have different orders of stops on a graph searching for the shortest path. The “temperature” would be a variable that represents how much random exploration you are willing to accept, i.e. if you alter the configuration and it’s worse, how much worse does it have to be for you to not accept it. A higher temperature would accept worse solutions, at very low temperatures you would only accept solutions that improve upon the route.

  I once implemented this algorithm to solve sudoku puzzles and it was very quick at doing so.

  There are tons of metaheuristic algorithms, and much of them we learn from nature, like annealing, however, there’s also genetic algorithms. The random exploration is done through random mutations through each generation, but the deterministic and greedy aspect of it is the fact that only the most optimal generations are chosen to produce the next generation. This is also a generic algorithm that can be applied to solve any problem. You can see a person here who uses a genetic algorithm to teach a computer how to fly a plane during a simulation.

  Modern AI is based on neural networks, which the greedy aspect of them is something called backpropagation, although this on its own is not a metaheuristic, but modern AI tech arguably qualifies because it does not actually work until you introduce random exploration like a method known as drop out whereby you randomly remove neurons during training to encourage the neural network to not overfit. Backpropagation+dropout forms a kind of metaheuristic with both a greedy and exploratory aspect to it, and can be used to solve any generic problem.

  Indeed, that’s how we get phones to recognize speech and convert it to text. Nobody sat down and wrote a bunch of if-else statements to translate text into speech. Rather, we took a generic nature-inspired algorithm that can produce solutions for any problem, and just applied it to speech recognition, and kept increasing the amount of compute until it could solve the problem on its own. Once it solves it, the solution it spits out is kind of a black box. You can put in speech as an input, and it gives you text as an output, but nobody really even knows fully what is going on in between.

  People often act like somehow computers could not solve problems unless humans could also solve them, but computers already have solved millions of problems which not only has no human ever solved but no human can even possibly understand the solution the computer spits out. All we know from studying nature is that there are clever ways to combine random exploration and deterministic greed to form processes which can solve any arbitrary problem given enough time and resources, so we just implement those processes into computers and then keep throwing more time and resources at it until it spits out an answer.

  We already understand how nature can produce things without anyone “knowing” how it works, because we do that all the time already!

• ⁨Comment⁩ on ⁨No need to boil the ocean⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  No, the point is that bacteria can produce toxins in between a company packaging a product and a person receiving it and then boiling it themselves. Companies have to kill the bacteria prior to shipping it. It’s similar to canned foods for example, they put it in the can then heat up the can to kill the bacteria, then ship it, so it shouldn’t have any harmful bacteria in there to begin with.

• ⁨Comment⁩ on ⁨No need to boil the ocean⁩ ⁨⁨1⁩ ⁨year⁩ ago⁩:

  Boiling things isn’t guaranteed to make it safe, because sometimes bacteria produce toxins as a byproduct that are heat-stable, so if you kill the bacterial you can still get food poisoning if you drink it.
