AI Thread Summary
Field variables include potential, strength, and possibly coilness, with the discussion focusing on the relationship between field lines and potential lines. It is noted that potential lines can only cross at singularities where the potential is undefined. The conversation emphasizes that potential and strength are not independent variables; rather, a field is fully determined by its potential function. The idea of potential growing spirally around a 'twister source' is introduced, linking it to the concept of vorticity, which is quantified by the curl of the field. This highlights the interconnectedness of field properties in physics.

fields local variables are its potential P, strenght E, and... coilness? 8)
hmm..is it possible that field-lines can twist around a center certain way that potential-lines can cross in one spot
 
Physics news on Phys.org
If a field has a potential, then potential lines can cross only at singularities: points at which the potential is not well defined.

By the way, it is incorrect to think of potential and strength as independent "variables". A field is completely determined by its potential function.
 
oops, you are right:)

i was thinking can potential grow spirally:
-field lines twist to a spiraloid around 'twister source'. what would it mean?
 
Sounds like you are thinking of "vorticity" which is measured by the curl of the field.
 
Thread 'Is there a white hole inside every black hole?'

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
