Hello everyone.

I was wondering why it was that we don't have any discussion of general physics. In the spirit of general education here I am.

Feel free to post questions of any kind regarding physics or mathematics useful in physics, I know I will help best I can and I hope others will too. As for myself I have a question:

I have trouble visualizing electrostatic systems. Electrodynamics I find easy (I am well versed in vector field analysis and calculus), but I have completely missed creating a mental model for electrostatics. I know the equations but it feels like a teachers password. Anything will probably help.

There are plenty of discussions, forums and resources online. Not sure how having another one here would help.

If you want more interactivity, the freenode ##physics channel usually has knowledgeable regulars almost round the clock. If you are not sure whether the person replying to you knows what s/he is talking about, check the channel access list, everyone on it has been vetted.

Can you describe in greater detail what sort of mental model you have for electrodynamics and lack for electrostatics? Since electrostatics is a limiting case of electrodynamics, I find your visualisation abilities puzzling. Is it really more difficult for you to imagine a scalar field than a vector field?

Hmm. I am unsure of that as well.

I guess I just need to find some formulations of electrostatic as scalar fields. Thank you.
