Every time he himself turns by an angle x relative to the ground beneath his feet, he also turns the arrow by -x relative to himself, so... -
Nugatory replied to the thread B Does a Probabilistic Multiverse Invalidate the Value of Scientific Inquiry?.You are starting from the premise that there is such a thing as a "multiverse". Maybe there is, maybe there isn't, but nothing in our...

Nugatory replied to the thread I Is there a bad intuition or bad explanation in quantum entanglement?.thank you, yes.

Nugatory reacted to Herman Trivilino's post in the thread I Is there a bad intuition or bad explanation in quantum entanglement? with
Like.
I can't speak for @Nugatory but my understanding of what he said is not that we shouldn't look, but that until we succeed in finding... -
Nugatory replied to the thread I Is there a bad intuition or bad explanation in quantum entanglement?.By proposing a further explanation. Until this happens there is no explanation, just as a book does not exist until someone writes it.
-
Nugatory replied to the thread I How strong is the justification for low probability extreme thermal fluctuations?.You have not thought through the implications of the question in post #16 of your other thread. Say that we set this random number...
-
Nugatory replied to the thread B Is a table levitating possible, even at a minuscule probability?.The way to get a levitating table is through classical physics: just by random chance a substantial fraction of the air molecules under...

Nugatory replied to the thread I Commutation of operators for particle in a box.Take ##\psi(x)## to be an arbitrary function and expand the commutator. You will end up with a term proportional to ##\frac{dV}{dx}##...

Nugatory reacted to dextercioby's post in the thread I Commutation of operators for particle in a box with Like.
Finite walls or infinite walls? Start down by writing the Hilbert space, then the two operators. You may discover that the commutator is...

Nugatory replied to the thread I Commutation of operators for particle in a box.Does it? We have ##[H,P]=[P^2/2m,P]+[V(x),P]##; the first term is trivially zero but there’s no reason to expect the second one to be...

Nugatory replied to the thread B What qualities does time have other than linearity, motion, and speed?.There's no sensible answer to your question until you have defined what you mean by the word "time". This being a physics forum where we...
-
Nugatory replied to the thread I Quantum Entanglement and Synchronization.No. There is no way of distinguishing a so-called collapsed state from an uncollapsed state (the “so-called” is there because even...

Nugatory reacted to pervect's post in the thread I Confused about time dilation -- motion vs energy with Like.
As others have pointed out, it's a bit more complicated than that. I'm guessing that you are assuming there is some state of "absolute...
-
Nugatory replied to the thread I Confused about time dilation -- motion vs energy.It cannot, because time dilation is independent of the energies and momenta involved. This is to be expected because time dilation is...

Nugatory replied to the thread I Quantum behaviour of an electron around a positively charged sphere.That's not a "serious" error, a serious error is something like flying a perfectly good airplane into a mountain because you thought...
