Interesting framing. But without measurements there isn’t really a need for different interpretations, is there? If that’s what you mean by “in the middle of an experiment”.
I will happily agree that before measurement, it’s very useful to think of the system as existing in many states at the same time.
I don’t know, Many Worlds always led to more confusion than Copenhagen for me. But I suppose that’s a matter of taste since they’re equivalent.
As per the relationship between measurement and entanglement, from an empiricist viewpoint all quantum mechanical terms are related to measurement. If entanglement didn’t affect the outcome of measurements, it wouldn’t exist.
Indeed, you can disentangle an entangled system, which of course will change the outcome of measurements - that’s how you know it’s been disentangled.
Copenhagen interpretation doesn’t break down for quantum erasure. Upon measurement you collapse the total quantum state into a result where the two measurements are consistent, that’s simply what entanglement means.
The timing of experiments, and the choice of what to measure, are elements ultimately irrelevant to the above statement, as the quantum erasure experiment demonstrates.
Unlike the Copenhagen interpretation, it does not privilege measurement over other types of interactions between systems.
Hmm, you could say it instead privileges the subjective experience over other types of interaction. There’s no reason in principle why you couldn’t experience every “world” at the same time, in the same way a measurement could in principle return all possible results at the same time.
But you don’t. Somehow your experience of reality is above unitary time evolution, even though “you” aren’t.
If you are reading this, you probably suspect that physics took a wrong turn about a century ago. You aren’t alone.
It didn’t. While new ideas are important and very welcome, the last century of physics has been brilliantly insightful and useful.
The legal framework for Greenland to declare independence has been in place for decades.
They’re currently a self-ruling territory that is part of the Danish realm by choice. Not saying that forgives old colonialist crimes, but it hasn’t been a Danish colony for a while now.
I guess that’s the joke - this is so stupid and obviously won’t work, but that perspective is subverted when it turns out to actually work, causing humour.
I quite like it.
I’d say there’s a difference between assessing people’s fitness to have children, and their fitness to raise children. The latter is a lot less eugenics-related, and clearly necessary in some form to protect children from being abused by their parents.
Though of course it isn’t always done perfectly or even well.
What does the parental test of this story have to do with eugenics then?
As I understand eugenics, it’s all about ensuring babies with “correct” genes are born and babies with “wrong” genes aren’t, so yes, preventing pregnancies or births seem to be at the heart of eugenics.
And doesn’t seem to directly appear in this story.
Yes, I believe so. Are you implying there’s some sort of contraception involved in this case?
These competence tests are being used on Danish parents as well, just to be clear. The law mentioned in the article is one that exempts the Inuit from being tested under the same conditions as other citizens in the kingdom.
To be clear, nobody is forbidding anyone from giving birth based on these tests.
All together now: there are no paradoxes in quantum mechanics
TBF imaginary time is a math trick and not something that actually progresses. It lets us apply results from statistical physics to quantum field theory through a Wick rotation.
Absolutely. Both me and my siblings. My parents were in an okay spot at this point, but they supported us to do far better.
Times were pretty borked compared to now, at least in this country.
I won an Xbox 360 a long time ago from a Coca Cola competition. You had to use codes from the bottle caps and then quickly answer some quiz questions correctly. But you had unlimited tries. So I just kept clicking random answers quickly until I got all questions right at a ridiculously low time.
Good times. Borrowed Guitar Hero, LA Noire, Batman Arkham Asylum and Red Dead Redemption at the library, had a blast.
Neat! Didn’t know that.
No. But I know true love, so I’d say you’re wrong.
