Look, Miguel, my million dollar education
certainly included the science of electrical
engineering. I bet you yourself do not know if the
generator that provides your home with electricity is
either a delta or a "Y" generator? What country do
you live in? But you see, we are not talking about
what I knew. I am the least on this net, and no one
should care about what I know. What do we know, as a
science, about our reality? We have no evidence that
our reality is 4-D. That is a fact that can no
longer be hidden. And we are going to do something
about it. Not because I know anything. We are going
to do something about it because that is what the
science demands that we do, and it demands that it
should be done now.


You would lose your bet. I have been a professor of electrical
engineering for 30 years now, and have lectured circuit analysis for
many years. I have told you before that SR was developed starting from
very simple AND physical considerations (for instance using things
like clocks and rulers). I gave you the Landau and Lifshitz reference
(Classical Theory of Fields) in which the first 20 pages treat in
depth most of the subjects normally addressed in this group. I even
told you that Landau clearly states (page 6) the use of a "fictitious
quadridimensional space". So using 4-D is just a tool that eases the
analysis, but the whole derivation is solidly based on physics, not
math. Just like in the "Y" or delta generators, phasors are used to
simplify the calculations and also to gain insight of other useful
properties, like showing that the 3-phase instantaneous power is a
constant.
