Dale reacted to PeterDonis's post in the thread B Need help understanding particle physics and quantum physics with
Like.
According to our best current theoretical models, they're quantum fields. Yes. This is much too vague. We can't give you a course in... -
Dale replied to the thread A Free surface problem in electrohydrodynamics.Yes. That is why I said “moving normal relative to the surface”.
-
Dale replied to the thread A Free surface problem in electrohydrodynamics.It doesn’t matter if it is small or large. What matters is the direction. If the charge is moving normal relative to the surface then...
-
Dale replied to the thread A Free surface problem in electrohydrodynamics.Not necessarily. As I said above, surface charge is not intrinsically tied to the bulk charge, but you could get a surface charge...
-
Dale replied to the thread A Free surface problem in electrohydrodynamics.Yes. That is what I am saying. This is an example of a scenario where there is not a surface charge.
-
Dale replied to the thread A Free surface problem in electrohydrodynamics.For a uniform ball of charge (eg a solid charged insulator) both the tangential and normal components are continuous at the boundary
-
Dale replied to the thread A Free surface problem in electrohydrodynamics.The bulk charge does not intrinsically produce a surface charge. Consider the case of a sphere with uniform charge density. In that case...

Dale reacted to stovenn's post in the thread B Applying the Gauss (1835) formula for force between 2 parallel DC currents with Like.
Hi thanks for your attention. TLDR: I have actually solved my primary goal of demonstrating that the Gauss equation gives the same...

Dale reacted to Ibix's post in the thread I Synchronizing clocks in an inertial frame if light is anisotropic with Like.
No you aren't. Dividing the round trip time by two and assuming that is the appropriate clock offset is an assumption of isotropic light...
-
Dale replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.Indeed, to be clear post a spacetime diagram with each event labeled and each signal indicated. And perform your calculations using one...
-
Dale replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.No. They know that at step 1 because that is the time in their own clock when they send the signal. They could be sending the signal by...
-
Dale replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.Also did you read all of the material on this topic that we posted last time you asked a question on this same topic...
-
Dale replied to the thread I Synchronizing clocks in an inertial frame if light is anisotropic.Umm, A can already determine t[B1] in step 1.

Dale reacted to Sagittarius A-Star's post in the thread I Synchronizing clocks in an inertial frame if light is anisotropic with Like.
Why is this given?

Dale replied to the thread B Applying the Gauss (1835) formula for force between 2 parallel DC currents.Which formula are you referring to here?
