Okay, so, like, that's punchier writing than the actual truth, but how am I supposed to buy anything else about physics in the article after that? The level of oversimplification of relatively commonly known concepts does not give me confidence that the rest won't be pop sci drivel.
Luckily you can check out the author’s bio right from the article:
Okay well maybe I'll circle back to it, then. Maybe bad science writing has made me a little cynical.
A bit of cynicism is always healthy!
Oh snap, so this guy is on the faaaaaaaar side of the bell curve wearing the hood and agreeing with me. Well played.
The guy just invents particles and you think we should trust him?
j/k
The concepts are basically right arent they?
I mean, they're both at least illustrative I guess. In the case of particles and waves I may be quibbling a bit over the distinction that something is a particle or a wave versus exhibiting the properties of one or the other.
In the case of Schrodinger's cat, the thought experiment suggests that if the life or death of the cat is tied to the collapse of the state vector, an eigenstate of the two implies simultaneous life and death. But the varying interpretations of this problem aren't so straightforward as 'both dead and alive', and it's kind of misleading to just leave it at that.
Personally, I find it odd that they'd discount the cat's own awareness of the state vector's collapse. Obviously when the atom decays and kills it, it's going to know before you are regardless of the presence of cardboard.
It just seems like a lot of kind of imprecise throw-away mentions of more complex ideas for one sentence. But again, maybe I'm being cynical.
I don't think he was planning to explain these concepts, just hint at them to the layman reading thr article who probably barely know what Schodinger's cat is.
Shrodinger’s cat wasn’t some simplified lesson for the layman. It wasn’t even an explanation. It was a commentary about the quantum model itself and how the current state of the model is laughably incomplete and unable to adequately answer or predict anything of value (yet). It wasn’t until more recently that some Newtonian physics might be explainable as emergent properties of quantum mechanics, but we are still a long ways away from a unified or blurred model.

And the cat observes it but that doesn't mean that the cat is now in a discrete state that is either alive or dead. It is both and will stay both and you'll only see which version of the cat is in your world. At least according to the many worlds theory which makes sense to me
