I gave references in my paper here. -
bhobba replied to the thread High School Interesting paper on QM in Scientific American.Von Neumann's famous writing on this in his classic text on QM never really caught on (and when I first read it, it left me scratching...

But then what is doing the observing? Ultimately, we would like QM to not even have such a divide--to be able to describe everything...

bhobba replied to the thread Undergrad Sean Carroll's description of the Many Worlds interpretation.Highly recommended, but very math-heavy. Fine for math nerds like me, but others may not enjoy it as much as I did. Thanks Bill

In the MWI, the universe is the universal wave-function. The universe doesn't split into two universes, as there is still the one...

bhobba replied to the thread Undergrad Sean Carroll's description of the Many Worlds interpretation.I rather enjoy Sean's books. But Sean does not point out one important fact (I can link to an advanced paper on it, but at this level...

The ##\alpha## and ##\beta## apply initially to the state of an electron, but after the interaction with a measuring device, they apply...

@DaveBeal, as my responses should show you, you can't just wave your hands about what the MWI says. You have to do the actual math...

No, it is one single wave function with two terms in it--each term is referred to as a "branch". There's no question of whether it...

bhobba reacted to Peter Morgan's post in the thread Undergrad Sean Carroll's description of the Many Worlds interpretation with Like.
In that book, Sean Carroll specifically focuses on Quantum Field Theory, with MWI as a side hustle. There are multiple ways to approach...

Sort of. There is only one wave function, which includes both branches; but in the wave function after the measurement, the electron is...

It feels old. Howsomever, my mind does keep writing checks my body can't cash!

There are old pilots and bold pilots but never any old and bold pilots.

I gave up at -9,431 I'm older and have been retired since 2012, so I go down a new rabbit hole every few years. It's been quantum...

Yes, but its absolute value squared is not exactly the probability density of photon position.
