Need to take my sandals off to count how many times someone's stated something along the lines of 'Thermal energy is the sum total of particle kinetic energy' or some such.

The refutation is a work in progress. Please chip in if I get some of the maths wrong.

Apologies for expanding tensor matrices out in full. It's the only way I can get my head around them.

Quick response.

No apology needed. That's the Engineer in you. Engineers have to get all the relevant numbers out of an analysis.

In my experience that means solving all the equations neatly bundled up in a matrix or tensor.

Only a Physicist can say ohm's law says E = Z I , where E is the circuit voltage vector, Z is the circuit impedance matrix and I is the circuit current vector., leave things at that.

An Engineer needs to know what all those voltages and current etc actually are, so has to solve all the equations one way or another.

Long term response

It will take some time to read through all 6 pages, but thank you for the thread.
