Rrenormalize replied to the thread In the early days of electricity, they didn't have wall plugs.Agreed, one could modify a standard two-terminal light socket to accommodate a ground terminal and make an adapter that would then...

Rrenormalize replied to the thread In the early days of electricity, they didn't have wall plugs.OK, that's a fair observation. But for those sockets, to which terminal would it be proper to connect a green (in the US) ground wire...

Rrenormalize replied to the thread In the early days of electricity, they didn't have wall plugs.I don't think those modern adapters have a ground wire either. I've never seen a light socket that could accommodate any additional wire...

The Jellyfish Nebula (a.k.a. IC 443, Sh 2-248) scooped up from my back patio, Feb. - Mar. 2025. The nebula is a supernova remnant found... -
Rrenormalize replied to the thread Using AI in experimental physics.Alas, I missed it due to a scheduling conflict. Did anyone else hop on the Zoom meeting?
-
Rrenormalize replied to the thread Direction of the magnetic field of an oscillating charge.How about integrating Faraday's law ##\nabla\times\vec{E}=-\frac{\partial\vec{B}}{\partial t}## w.r.t. time ##t## to get...

Rrenormalize replied to the thread A Free surface problem in electrohydrodynamics.So do you agree that the authors meant to write ##\nabla## and that their eq.(2) is therefore not nonsense?
-
Rrenormalize replied to the thread A Free surface problem in electrohydrodynamics.I think that ##\nabla^2## is just a typo; it should instead be the vector-operator ##\nabla## according to Fick's laws of diffusion. The...

Rrenormalize replied to the thread A Free surface problem in electrohydrodynamics.OK, I can see from your attached paper that you are quite knowledgeable regarding EHD, so providing a detailed answer to your question...

Rrenormalize replied to the thread A Free surface problem in electrohydrodynamics.You say in the first line of your abstract: Research on free-surface flows in electrohydrodynamics has predominantly focused on the...

Rrenormalize replied to the thread A Free surface problem in electrohydrodynamics.The OP posits a fluid medium with a constant bulk charge density and so it carries a nonzero total charge. Assuming that the fluid does...
