--- Quote from: RudySchneider on April 02, 2008, 04:00:14 pm ---Quote from Wikipedia entry for dielectric:

"Many phenomena in electronics, solid state and optical physics can be described using the underlying assumptions of the dielectric model"

--- End quote ---
They can be described, but a dielectric is a material that has the ability to store electrical charges. I think the word should not be applied here.

RudySchneider:
My goodness we're stubborn!  Then again, it's obvious you didn't look at the Wikipedia entry for dielectric.  So, I'll quote from there, again:

"Dielectrics ... are not a narrow class of so-called insulators, but the broad expanse of nonmetals considered from the standpoint of their interaction with electric, magnetic, of electromagnetic fields. Thus we are concerned with gases as well as with liquids and solids, and with the storage of electric and magnetic energy as well as its dissipation."  And by the way, light is in the magnetic spectrum.

I'm an electrical engineer, so I appreciate your comfort level with Webster's definition, "a nonconductor of direct electric current," but I prefer the broader, systems-level implications to which Wikipedia refers.

I do not always agree with wikipedia definitions, but that doesn't mean I'm stubborn. If you see the origin of the word "dielectric" it means "two electrical poles". By your classification metals are also dielectric, because they interact in a special way with light. Actually, photons loosen electrons from the metal atoms. When the electron falls back to a lower energy level, it sends a photons. That is why metals are so shiny. But they are unable to store different electrical charges because they are conductive.

RudySchneider:
Good observation and argument, cumesoft.  And while I don't fully share your views, respect, acknowledgment, and appreciation for different insights and opinions is always a good thing.  Good discourse helps to expand and exercise the mind.

Indeed. Well said.

I must add that if all people had the same pattern of though, the world wouldn't evolve and all ideas would eventually fail at the same time. Because ideas are different, if one fails the other persists, and there is always space for adaptation and always new knowledge to cultivate the mind.
