PeterDonis replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.Which "metric compatible equation:"? There isn't just one. There are as many different metric compatible equations as there are... -
PeterDonis replied to the thread I Does a qubit break interference in the double slit experiment?.Only if the result of measuring the particle is only consistent with one given result for the qubit. Whether that's the case will depend...

PeterDonis replied to the thread I Does a qubit break interference in the double slit experiment?.There are already plenty of calculations in the literature showing how which-way information can destroy interference. There are also...
-
PeterDonis replied to the thread I Does a qubit break interference in the double slit experiment?.Not as stated, no. If all you have is the qubit, you've just entangled the qubit with the particle going through the slits. Decoherence...

PeterDonis replied to the thread I Does a qubit break interference in the double slit experiment?.That isn't a quote from @pines-demon. It's @pines-demon quoting from the transcript of the podcast he linked to.

A vector ## \ket{\Psi} ## in Hilbert space, multiplied by any complex number(*), represents exactly the same state. That's why it is...

PeterDonis replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.No, because "compatible" isn't just one thing. "Compatible" if the connection is the Levi-Civita connection gives you one equation that...

PeterDonis replied to the thread Does it make sense to build new radio telescopes?.Then it probably wasn't a good idea for you to describe explicitly in this thread how to do that. (Not that I think the radio astronomy...
-
PeterDonis replied to the thread I Violation of Bell Inequality with unentangled photons.Your two assumptions are inconsistent. If a classical model matches the experimental results, the experimental results cannot violate...
-
PeterDonis replied to the thread Does it make sense to build new radio telescopes?.I still don't understand. You're describing ways in which the accuracy of detection could be improved. That would involve continuing...

PeterDonis replied to the thread Insights Quantum Entanglement is a Kinematic Fact, not a Dynamical Effect.You might not understand that @Greg Bernhardt did not write the Insights article that is referenced, and is not the right person to ask...

Like.
Basic research is founded on the basis of advancing knowledge, not with necessarily achieving a particular goal. History has taught us... -

If you were right, then why are the observation times on our existing telescopes notoriously overbooked? Source: ALMA Certainly not...

PeterDonis replied to the thread Does it make sense to build new radio telescopes?.I don't understand. Changing location--to space or on the Moon--does increase the resolving power available. You've explained why...
