    So the thing that gets weird is that the heavier the particle is the more likely it is to interact with the slits themselves on the way through, in which case the wavefunction will collapse and it will seem to go through only one slit. Also, as the other person stated, even a hydrogen atom is really 4 fundamental particles that can interact with eachother. I’m not totally sure if double slit has been demonstrated with atoms but I do know it’s been done many times with electrons.

    Edit: its actually totally possible to do it with much, much larger things. From wikipedia:

    The experiment can be done with entities much larger than electrons and photons, although it becomes more difficult as size increases. The largest entities for which the double-slit experiment has been performed were molecules that each comprised 2000 atoms

    And here’s the study that did it: https://doi.org/10.1038%2Fs41567-019-0663-9

    Ehh, its a bit more than that.

    Its a particle in that we know they are quantized into single photons. As in, it is impossible to observe half of a photon, or any non-integer number of photons, and one photon can only be observed in one place. This makes it like a particle.

    But its a wave in the way it behaves - it can interfere (not just with other photons, with itself), and its movement can only be described through wave functions that can even take seperate paths at the same time, according to how waves propogate.

    And, there are ways in which they act like particles no matter how they are observed, and same for wavelike behavior

    Worth noting: “observation” is just physical measurement. You have to keep in mind that observing something fundamentally requires interacting with it - in order to look at an apple, photons must bounce off of it, which is a physical interaction. On the quantum scale, these interactions cannot be ignored.

    Also also: this isn’t just photons, everything is like this. It may not align with how we observe things on a macroscopic scale, but this is fundamentally how the universe works.










  • I find it very promising. As much as I love meat, its pretty undeniable that raising livestock is super inefficient. It takes so much food to raise livestock that, iirc, more farmland in the US is dedicated to growing food for our food than to growing food for us. Lab grown meat doesn’t completely solve this - there are still lost calories in the process to my knowledge - but its way more efficnient. Plus less land usage, less fossil fuel emissions, overall it would be more sustainable.

    I see 2 big problems facing it right now:

    The first is scale, which is the more significant. We’d need to figure out how to grow meat on a truly massive scale. Definitely doable though, just needs more research.

    The second is “realism” or how close it seems to natural meat. Lab grown meat has the advantage over like plant based stuff because it is actually meat. However, ifnits too perfect or uniform, or maybe doesnr have enough fat or variety, it might be seen as unnatural by many (even just subconsciously) and push them away from it.

    But yeah, could be awesome.



  • Ok, the openAI thing is not great. However…

    they advertise themselves as degoogled, but instead let you connect to Google/Microsoft/etc services

    What the fuck are you talking about? Degoogled doesn’t mean you shouldn’t be allowed to connect to Google services. It just mean that it doesn’t require Google services to function and that the default configuration shouldn’t include any Google services. If the end user actively wants to use google/microsoft/etc services then they should be able to. It seems as though you are advocating for an open source operating system to lock itself down from allowing the end user to use certain features, which is against the FOSS ethos. Remember, “free” as in “freedom.”
