    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


  • I mean I could almost see that? Helldivers is kinda a satire on the american brand of fascism so it could be argued its an anti-fascist peace of media. But that’s a stretch to say the least.

    But my real issue with this is that federal investigators saw something they had absolutely no clue what it is and called it a transgender symbol. Its an incredible amount of bias in a particularly very bigoted way.

    Reminds me of a lyric from The Clash - “taking off his turban, they said, ‘is this man a jew?’” They see something unknown to them and just assign it to the marginalized group they have a preconceived notion of being bad.

    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.


  • Ok but these are meant to be in bike lanes, sharing space with regular bikes. Part of the point of bike lanes was because it was dangerous for bikes to be sharing space with vehicles that can go so much faster than them.

    Edit: imo if it has a throttle which can be used to keep up with motor vehicles then it is a motor vehicle. It should be classed with motorcycles.

    If its gonna be considered a bicycle, it should have at the very least a speed limit on the throttle, or maybe no throttle allowed at all and pedal assist only.










  • I have mixed feelings on this one, tbh

    On one hand, that was actually the original name. That changed after WW2 and to be honest I kinda think the name was part of a greater campaign to make it seem as though, somehow, the military actions that followed in the next few decades in the middle east, Asia, Latin America, etc. were actually all just “defending” the US. Which is bullshit.

    On the other hand, having perhaps the most insane president this country has ever seen saying that calling it war instead of defense because its more accurate to the current times is quite concerning to say the least.
