Some more interesting discussions with Ed Dellian has resulted in this ‘summary’, made in context with my current level of understanding of Catt Theory of electromagnetism):
- Energy current (E-vector) causes momentum p.
- Causality is made via the proportionality coefficient c (speed of energy current)
- Momentum p is what mediates between E-vector and changes in the matter.
- Momentum p is preserved as energy current hits the matter.
- Momentum in the matter presents another form of energy (E-scalar).
- E-scalar characterises the elements of the matter as they move with a (material) velocity.
- As elements of the matter move they cause changes in Energy current (E-vector) and this forms a fundamental feedback mechanism (which is recursive/fractal …).
Telling this in terms of EM theory and electricity:
- E-vector (Poynting vector aka Heaviside signal) causes E-scalar (electric current in the matter).
- This causality between E-vector and E-scalar is mediated by momentum p causing the motion of charges.
- The motion of charges with material velocity causes changes in E-vector, i.e. the feedback effect mentioned above (e.g. self-induction)
I’d be most grateful if someone refutes these items and bullets.
