  • Whilst I’ve heard this idea said plenty of times by scientists as a way of demystifying the double slit and similar experiments, it doesn’t really do justice to the weirdness of the quantum world.

    Firstly in the “default” interpretation there’s no mechanism or explanation for how an observation causes wavefunction collapse, it’s just a rule that it just does that. And the collapse doesn’t correspond to a change in momentum of a particle or any other change in classical physical state, but something else entirely.

    In the double slit experiment a detector at one slit somehow seems to affect the particle as it leaves the source, before it reaches the detector (so the effect is backwards in time!) And without the detector it goes through both slits at once.






  • At the risk of explaining what everyone here already gets: I like how the bottom picture could literally be a diagram of a 4-way deadlock where the buses are threads of execution and the roundabout exits are object locks.

    Whereas in top picture there are no passengers and I’m fairly sure the buses aren’t moving. Which probably says something about the state of the documentation

    The percentages all seem low, I would usually assume that everything except the bottom tier is 95%+ liked. I suppose there’s not many vegetarian options here which must be a factor.

    Personally I’d say yes to all the others but I don’t think I’ve ever tried jellied eels. Anyone know if they’re they any good?
