I have added an additional section to chapter 8 of the textbook, on the intrinsic structure of fields. This completes the section of unified fluid dynamics in a suitable way, as I think. The Résumé is:
The path of arguments is based on experimental facts. It is explained what a field really “is”. These ideas are new in the ECE context. Standard physics cannot give an answer to this question. It only knows the effects of fields and ignores this question. Some “out of the box” thinkers like Nicola Tesla and Tom Bearden have given answers to this question, but could not integrate their results into the frame of complete physics. This should have been successfully achieved through the current work.
