The thread Title is: "Could a cell membrane

I stand on what I posted.
Why do you think the RF is interpretable?
It's the always-there-ness of both E and H.
Set H, and you also set E.
Think I'm "imagining"? Or post-posting?
Google sufficiently, and you'll see that
I've accurately discussed it all in the past.

Hey, that's not my 'fault'.
But the Problem you've noted is worth
discussing, a bit.
I work at the edges, Matthew. That means that
the stuff I discuss has never been discussed
before. It's always this way. With respect to
the post that we're both discussing, here, the
'point' from-out-at-the-edges that I was dis-
cussing was [is] with respect to the way that,
within nervous systems, "directionality"
The way I wrote my post was [literally] calc-
ulated to evoke an image of "directionality"
within the reader's consciousness.
To do this, I used folks' awarnesses of MRI
images, and referred them to the way that "The
magnetic field would vary with the distribution
of the cellular constitution."
I was 'painting a picture' of "directionality", and
how one sort of information-content, an MRI
image, is derivable in-it.
Am I "satisfied" with the imagery?
Which is why I'll keep explaining stuff that
folks, probably including you, don't [yet] understand.
