  • 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.

    Ah yes, crying about “privilege” while you’re here demanding that people shouldn’t speak out against a literal modern day holocaust at the only time when they have the political power to make some sort of difference. Yeah, it’s totally those people who are “privileged” and not your white pasty ass who doesn’t have to worry about their extended family being slaughtered.


  • 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.

    Good. That’s when Democrats should be criticized the most, because that is the only time you have the power to exercise any leverage over them. Why would you refuse to criticize them when you actually have a tiny bit of leverage and wait until you have no power at all and your criticism is completely irrelevant and will be ignored? That is just someone who wants to complain but doesn’t actually want anything to change.



  • I am an American and i own an electric kettle and use it frequently. I switched to an electric kettle after accidentally turning my microwave into a smoke bomb when I put instant ramen in there and forgot to add the water. Now I only make instant ramen with hot water from a kettle or on the stove.



  • In Cuba they have a law that requires you to sell your house if you buy a new one. That also means you can’t be a landlord or else you yourself would be homeless. They also have a law that guarantees that if you don’t own your own home, you at least get public housing guaranteed, which has rent capped at 10% of income so it can never exceed that. They have the lowest homelessness rate in all of the Americas.

    It always impresses me how much people worship landlords, even Canada up there is having a housing crisis but nobody dares question the sanctity of landlords. You can watch both the major parties arguing for hours and nobody ever brings up landlordism once. A lot of them choose to instead become hostile to immigrants, both parties moving further right on immigration because stopping immigration or potentially even kicking out immigrants to them is more acceptable than questioning the sanctity of landlords. You also saw a similar thing here in the USA, I remember after the Trump/Kamala debate when they revealed the plans for bringing housing prices down and Trump was “mass deportation” and Kamala was “a tax credit.” Not sure about every country definitely here in US and Canada, people here treat landlords like unquestionable deities, the idea that their right to rule should even be called into question is not even something that passes through most people’s heads.




  • Well, what is boring and non-boring I guess is in the eye of the beholder. What I moreso was referring to is what is difficult to wrap your head around.

    The nondeterminism is kind of unavoidable as long as you don’t want to change the mathematics of the theory itself, but I also don’t really consider nondeterminism to be that unintuitive or difficult to “understand.” I mean, throughout most of human history, it wasn’t that common for humans to actually believe in determinism in the Laplacian sense of being able to make absolute prediction to the future based on complete knowledge of the past, that was largely popularized with the rise of Newtonian mechanics, and even by the 19th century you had even a lot of materialist philosophers calling it into question on grounds of logical consistency. Personally, I think the strong desire to maintain Laplacian determinism is really a physicist thing. They work with Newtonian mechanics first and it becomes so intuitive some don’t want to let it go when it comes to quantum mechanics. But I doubt if you went and talked to the average person, most probably wouldn’t be that strongly adherent to Laplacian determinism.

    The kinds of views I was talking about are more things like people who try to interpret the state vector as literally representing a physical wave spreading out in space that collapses like a house of cards when you perturb it, or try to envision a literal multiverse where everything is just a big “universal wave function.” A lot of these bizarre views are not only unintuitive but literally impossible to visualize, and they run into a lot of problems in logical consistency and there have been mountains papers and books published on the subject trying to work out all the conceptual issues. If you are a person just learning QM and the philosophical interpretation around it bothers you, if you listen to people who talk about these weird things, you will need to read through dozens of books and maybe even hundreds of papers just to get a general idea of what is going on, and even then most of these interpretations still have not resolved their mountain of conceptual issues.

    To me this really bothered me when I got into quantum computing for the first time. I wanted to not just learn the math but have some sort of intuition of what is actually going on. I then went down a rabbit hole of reading tons and tons and tons of books and academic papers to try and find some way to make the math make sense on a philosophical level. Most of the mainstream views you see in the popular media just overcomplicate things for no reason because the person wants to make QM sound more mystical than it actually is. What I ultimately came to realize is that most of this confusion is just self-imposed in the sense that they are based on assumptions which are not actually demanded by the mathematics and entirely optional (such as interpreting a list of probability amplitudes a literal entity in a physical space) and thus most can be stripped away.

    You can’t strip away every aspect of QM that makes it unique, because it clearly does differ from classical mechanics, but by dong this you do really hone down on what actually makes QM unique and what is genuinely an unavoidable consequence of the mathematics. And what you get down to is just interference effects, which arise from the fact that probability amplitudes are complex-valued, thus can cancel each other out, which can’t occur in classical probability theory. Nondeterminism and context-dependence then follow from this as a necessity for the theory to be logically consistent, but both of those are fairly easy to have an intuition for.


  • ngl I blame physicists who communicate to the public for this

    Notice how you always see a lot of nonsense mysticism around quantum mechanics like “quantum healing” but you never see anything along the lines of like “general relativity healing” or “inflation theory healing.”

    The difference is that often it is the physicists themselves who choose to communicate to the public who paint quantum mechanics in a mystical light. Indeed, this is not even something unique to the physicists who communicate to the public, you can sometimes even run into it in peer-reviewed publications painting QM as a theory that somehow puts conscious observers front and center and questions the existence of objective reality, or whatever rubbish philosophy people try to imbue onto some linear algebra.

    The ones who communicate to the public just are often worse because they don’t tell you QM as it really is, they usually tell you some personal theory they have. For example, rather than just describing how QM works, one of these science communicators might tell you their personal theory about how there’s a grand multiverse, or that “consciousness” plays some sort of role, and that explains why QM works. They do not just present the theory, but their own personal speculation as an underlying explanation for it.

    Because physicists themselves promote all this mysticism around a bunch of linear algebra, you end up with mystics and charlatans who realize that they can take advantage of this by talking about mystical nonsense like “quantum healing.” Sure, it might be nonsensical rubbish, but the person who hears about “quantum healing” also heard a real PhD physicist tell them about multiverses and “consciousness,” so they think there must be something to it as well. It gives the mysticism an air of legitimacy.

    We like to kid ourselves that the mysticism is just promoted by your Deepak Chopra types or laymen who have no idea what they’re talking about. But if you actually look at what a real academic philosophy department publishes, there is mysticism all throughout academic philosophy. These philosophers have also had a big impact on physicists, who often adopt these mystical attitudes they learn from the philosophy department into their own discussion, and sometimes even into their own publications.

    If you actually talk to the laymen who are deeply enthralled by those quantum mystic pseudoscience charlatans, they usually can point you to multiple real academics who back their beliefs, people with legitimate credentials. This is a problem nobody seems to address and it annoys the hell out of me. Everyone paints either the charlatans or the laymen as the bad guy here, but nobody wants to talk about the elephant in the room which is the rampant mysticism in academia.

    I literally argued with a PhD physicist the other day who was going around preaching to people that quantum mechanics proves that there is no physical reality and we all live inside of a “cosmic consciousness.” I did not get very far with him because he just insulted me and pointed to academic philosophers who agreed with him and said I’m stupid for even questioning his claims, and then wouldn’t address my criticisms.


  • I am saying that assigning ontological reality to something that is by definition beyond observation (not what we observe and not even possible to observe) is metaphysical. If we explain the experiment using what we observe then there is no confusing or contradiction, or any ambiguity at all. Indeed, quantum mechanics becomes rather mechanical and boring, all the supposed mysticism disappears.

    It is quite the opposite that the statistical behavior of the electron is decoupled from the individual electron. The individual electron just behaves randomly in a way that we can only predict statistically and not absolutely. There is no interference pattern at all for a single electron, at least not in the double-slit experiment (the Mach–Zehnder interferometer is arguably a bit more interesting). The interference pattern observed in the double-slit experiment is a weakly emergent behavior of an ensemble of electrons. You need thousands of them to actually see it.
