Directional wires/cables

“..the label aligns with the flow of electrons” electrons in cable move only for DC connection! All audio signals’ are AC, thus electrons are only shaking both ways, and generate EM wave moving from source to load! Not absorbed EM wave in impedance mismatched signaling schemes, such as “RCA <=> high input impedance and low output driver impedance”, creates reflections, thus time domain signal distortions.

@r27y8u92 -

     Here's a rehash, of something I posted in response to a thread entitled, 'Ok, but does your audio gear have rotons (metamaterials)?', back in 2021.

     The skill of paragraphing on this site had eluded me, at the time.

                         The following should be an easier read.

     Don't take anything toward the end of the post personally, as it was in response to a genuine dolt, back then.

           Back in 1927 Vienna, at the fifth Solvay Conference on Physics, some of the greatest minds on the planet (ie: Einstein, Bohr, Schrodinger, Heisenberg, Curie, etc) got together to discuss things like photons and electrons.   

            Arguments quickly ensued between those that wanted the universe to make sense, based on classical Physics and/or Relativity and those that were theorizing about quanta (packets of energy) and how so many things, observed in their experiments and in their theorems, based on such as Planck's Constant and Heisenberg's Uncertainty, seemed irrational. 

            Every day: Einstein would come up with an objection, as to why such must be in error and by evening: Bohr would have an answer.   

            As an example: Wave-Particle Duality.      Einstein wanted electrons to just be solid particles, all the time.    Bohr asserted that they existed as fuzzy/indistinct waves, with no particular position.   Only a multitude of possibilities, until observed or detected, at which time, they become particles.  

             Einstein replied, "So, you're telling me the moon doesn't exist, until I look at it?"   

             Anyway, that's a miniscule, much simplified slice of what took place then.               

             What followed that conference, is a matter of history and experimentation.   

                                                        Some proved Einstein's assertions. 
                                                                      Others: Bohrs    

              Probably: the resultant inventions that are most notable, whether you believe them to be evil or not, were the Atomic and Hydrogen Bombs.  

                                                    Obviously: Quantum Mechanics works.   

               One of the arguments, of which I was most interested, back in the 60's, while studying Physics, was that of Entanglement (if a photon or electron are split into two entities, each when detected/observed, will exhibit identical properties (spin), whether across the room, or across the universe.    Einstein called it, "spooky action at a distance".  

                To make it fit with Relativity, his universal speed limit (speed of light) and make any sense, at all: he postulated that when a photon is split in two, both (at the source) already have those properties determined.     

                 Quantum Mechanics stated they exist as wave functions and don't exhibit any properties until observed/detected, at which point the information is instantaneously communicated (again: regardless of distance).      

                 No one had a theorem, by which to test that, until a guy named Bell (who I believe to have actually been ambivalent about the whole thing) came up with one.   He lacked the means by which to test his math, however.     

                 Then: a couple guys at Berkley, California cobbled some equipment together and proved the Quantum Mechanics view correct, using Bell's theorem.    

                 You can deny the facts, until you're blue in the face, BUT: without what's been gleaned from the study of Quantum Mechanics: we wouldn't have a few of the inventions that, I'll just bet, most of you have in your homes.  ie: LASERs, GPS, anything digital (computers, cellphones, smartphones), semiconductors (ie: diodes, transistors, ICs, etc), the electron microscope, and MRI (well... maybe those two: not in your home).  

                                                             The list could go on.     

                  Then, there's Nicola Tesla.   Make fun (if you will) regarding his belief in Quantum Mechanics, but he's to be thanked for the AC you're enjoying, in your home.     His inventions and genius* took the likes of you Deny'intologists, kicking and screaming, into the Twentieth Century.   

                   *ie:  Ever heard of the Niagara Falls Power Project?

       My point always is (refer to my prior posts): no one has all the answers, yet! 

                                                      Happy listening!                                   

                         Still working on those paragraph/typing skills.

     In the Feynman/QED model: the electron oscillates and generates a virtual photon/particle.

                  Someone mentioned liking to hurt their head?

       Dielectric polarization also comes up in the discussion, toward the conclusion and Feyman diagrams.

@rodman99999,

Would I be wrong saying nothing, life, would exist without EM waves?

I ran across this video years ago which, to me, says life would not exist.

Electromagnetic waves and the electromagnetic spectrum

(To watch the video X out of the blue box by clicking on the white X upper right hand side of blue box. Then press start.)

Audio frequencies would be to the far left of the electromagnetic spectrum. My understanding because of the audio frequencies EM wavelengths wires are required to guide the EM waves from the source to the load.

What say you?

And or herman?
