| : | out of them. Here's one of interest to your double star studies.
| : | http://web2.airmail.net/nptbs/doc/DIEL.doc
| : | I haven't given it a good read but I want to make time because
| : | it is closely related to displacement current.
| :
| : I gave up here:-
| : "Perform this thought experiment or even in reality. For the glass
| jar, let
| : it become thinner and thinner until it is only one molecule thick".
| : I figured my rolling pin wouldn't work, it's a wooden one that has a
| surface
| : accurate to 1 micron only, which is way too big, and my oven has never
| : softened CorningWare to sufficient maleability.
| :
| Yeah... my brain started getting mushy about the same point but
| I think in he making the point that the matter (surface) that is the
| biggest and closest is what you have to consider. I sort of got
| side tracked by the "shell games" with the materials and need to
| read it again. I think he is saying something... just not very
| clearly.
Seriously though, all physics boils down to one basic principle,
action at a distance. We look at any aspect, it always comes back to that.
For there to be any action, there has to be an actor/actee and an
actee/actor,
and there is always distance between them, that distance being filled with
nothing. I cannot envisage a massless (and indeed solid yet liquid yet
gaseous substance that is totally inert, save for the mechanical
transmission of pressure of some kind jamming itself between the electron
shell and the nucleus of an atom, let alone pervading the entire universe.
All matter (whatever that is, electrons/protons/neutrons, the stuff they are
made from), interacts with other matter over a distance that is not matter.
For gravity,
we've no dielectric to consider. For electromagnetism, we can consider
intervening matter between the actor/actee pair acting as a dielectric, but
it is
itself composed of matter, a kind of catalyst for the enabling/disabling of
the action at a distance that is apparent between two magnets separated by a
sheet of paper or the charged plates of a capacitor. The matter itself is
only the monopole, the centre of the field that is the action at a distance.
We can all write m = E/c^2, but that is only a clue as to what is really
going on.
I think we are at a position where we can say electrons exist, action at a
distance happens, and little more. We can propose our ideas and say what
things are not, but do very little in saying what they are.
So I'm open to suggestion from any quarter, but don't be surprised if it is
rejected.
