Like.
...and there you go citing measurements and observations to try to prove that just measuring and observing isn't enough. -
PeterDonis replied to the thread High School I don't understand the Michelson–Morley experiment.The fact that nature acts according to predictable regularities, which is what you're saying here, is a much weaker statement than the...

PeterDonis replied to the thread High School I don't understand the Michelson–Morley experiment.You're misdescribing the theory. It doesn't say the motion of the air around the wing is a circle. It says that the circulation of the...

PeterDonis replied to the thread High School I don't understand the Michelson–Morley experiment.How do you know?
-
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.One possible item: I assumed in my previous posts that the operator ##U## realized by the Bell state analyzer was unitary. But it might...
-
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.To be clear, the kets that ##U## operates on are kets at the input channels to the BSM/SSM (the ones labeled b and c with no primes in...

PeterDonis replied to the thread High School I don't understand the Michelson–Morley experiment.Please give some.
-
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.If I discard the concerns I raised in my last two posts, and just try to compute this from the evolution given in the Ma paper, I get...
-
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.Indeed, looking at this and the diagram of the experimental setup (Figure 2 in the paper) makes me even more confused, because the...
-
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.Unfortunately, after looking at this, it doesn't tell us what we need to know. This evolution starts with the two distinguishable Bell...

PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.Can you be more specific?

PeterDonis reacted to Matterwave's post in the thread Undergrad Spatial separation of entangled particles implies physical separability? with Like.
By "independence" here, do you mean statistical independence of measurements? In analyzing an argument such as EPRs, it is best if we...
-
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.This might be one of those cases where we have to be very careful about distinguishing two different cases, which intuitively "look the...
-
PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.Yes, and something more like my post #76, where I described what my account would look like for a setup in which all four Bell states...

PeterDonis replied to the thread Undergrad Entanglement swapping and Bohmian mechanics.But, as I think has already been noted, this implies backwards in time causation. Which means... ...this can't possibly be true, since...
