I quoted a fact. No more, no less. The quote is entirely correct. You read exactly what you wanted into my quote to suit your own purposes. Your inferences are precisely that, and not mine

Why are humans so homogeneous? 10000 years ago, most humans were wiped out. Down to just a few. couplea thou. Then you got your Genghus Khan who knocked up so many, that now, one in ten in asia, are directly related.
The F word denotes Fornication under consent of the king. But humans are notoriously promiscuous. We must have a little of the strange stuff, even if you are cro magnon, and the hot stuff is Neanderthal. So, attempts to direct selective human breeding come to naught.
This is not to say there are not vast variations in one individuals senses and another. Some see colors as sound. And visa versa. Some drugs color perceptions. Some permanently. Fortuitous mutations are not rare, but rarely go dominant. Evolution seems to operate in fits and starts, due to environment, and seeming advantages like heightened senses don't appear to become mainstream. Thus, golden ears, or perfect pitch, is more likely due to something like compensation, as in idiot savant, or aspergers. Blindness or such.
Those things that might have given us a situational awareness advantage, like better sight, or hearing, healthier etc, are not given their full Darwinian survival expectation. Even the Neanderthals cared for ill and diseased members.

You better stick on your own business profession and leave to electricians the rest regarding material evaluation.
Are you using twisted pairs CAT4 at 1Mbit networks instead CAT6+ or better? because even this is a hype in your eyes?
CAT standard cable is engineered, not some audiophile myth based cable...
The cable between the mains socket outlet and the equipment that needs mains power is just a simple 2, or 3, core copper clad in two layers of insulation.
Well it's not that simple. That cable pair (excluding the PE) has an impedance. That impedance can have a filtering effect on the current passing to the equipment.
The biggest filtering effect will be at the higher harmonic frequencies and at the higher interference frequencies.
A cable that is pure resistance and has zero reactive contibution cannot filter unless some other reactive component is installed in the equipment.
But that argument when reversed implies that the reactive impedance of the cable can have a filtering effect, even when there is no added reactive component in the equipment.
All the foregoing should indicate that changes in the proportions of resistance and capacitance and inductance of the mains cable can have different filtering effects on the higher frequencies included with the mains fundamental that comes to our equipment.
It's the different reactive parameters of the cables that can change what is delivered to our mains powered equipment.
Sometimes those differences will be audible.
Even when it is not audible, it will usually be measureable. Measurements will reveal much.
Maybe that's why many cable suppliers existing in the exotic priced end of the market do not include data. It would show their cable to be inferior to "ordinary" cable with "ordinary" reactive cable parameters.
Russ Andrews I believe got a wrist slap for claiming their cables had a filtering effect... the effect with mains cable is going to be very very very very very small.
This has certainly gone right off the rails.![]()
People certainly got charged up by the discussion. Maybe even a few sparks flew. 😛
What it boils down to is, use materials for their intended purpose. Many of our advances, are space crap. So, you use exotic materials in space, to get as good a signal etc transfer as possible, and as reliable as possible. And doesn't change over time.
All else is jewelry. BUT, in every game, achieving that, is quite a ways up the beautiful engineering solution scale. And so what if you add a little bling? You don't say, I will ONLY add performance parts to my sportscar. Some are embellishment.
But, the sales shtick, where you just gotta wait and believe, when they finally gel, is bunk.
Oh, I am as one of my hats, a product designer, and even I am smart enough to know that just being good aint enough, you gotta look pretty.
Pretty much normal copper based cables, no fancy metals, same with the PCBs just omit the solder mask....
How can you be so sure, how my personal brain is wired and how my mind works? I consider it ridiculous to claim how the senses of another living being work.
And no, you cannot convince me with modern biological and psychological scientific "proofs" simply because science still develops. And this simply means - it isn't perfect. Period.
LOL a true believer... no matter what proof is put in front of you, you will deny it....😀

I am sure of one universal proof. The world we perceive and the proofs we know only exist the way they are through our 5 senses.
Trying the standartize the understanding of the universe through science that is still developing and claiming definite "proofs" is just ridiculous and arrogant.
But of course, life is much easier to understand by simplified science. Why making your life complicated? In a power cable for example, AC current travels at 50/60 Hz and nothing more. Why would a piece of wire from the wall make a difference? It's easy to blame the human nature for psychological problems. 😀
I am just curious. How can a human being that has so many psychological flaws and imperfection claim about laws and proofs?

That is called naive perception. I learned that things aren't the way that my 5 senses portray them the first time I encountered a mirage, which was maybe when I was 4 or 5 years old. No mirages where you live? Don't go out?
The science of perception finds that there are two types of perceptions, those that are veridical or reliable, and those that are illusions. Nobody ever showed you any of the well known visual illusions?
Well then, its time to show you how people with a little more experience in life see things. Read here:

What is arrogant to a large extent is the believers trust in their infallible hearing abilities, whereas us lesser mortals use BT and DBT as well as science and engineering to determine whether our senses are fooling us or not. Any claims made on any sighted hearing is invalid as proof without further evidence....
AC current does NOT travel at 50/60Hz it travels at a ratio of the speed of light determined by the dielectric material the EM waves are travelling through actually... or for a lossless transmission line....

Further the electrons will travel at approx. 0.1mm/sec so wont even leave the cable in most cases, but just jiggle about.

You're right about how people with a bit more experience in life see things.
I tend to see strange things after drinking a litre of vodka. But I can always tell illusory objects from real ones. That's real proof of the science of perception actually working

You are aware, that with that obscure science that doesn't understand or now anything, it is perfectly possible to PREDICT mathematically how nature behaves up to parts of an atom?
I was more thinking of electrons in circuits, chemical reactions and the likes.
Thermodynamics are a tough field and "the weather" is tough to predict but even that can be handled pretty well. How off is the weather forecast usually these days?

Can the wingbeat be quantified? Because when it can then the prediction can take care of that. This is not a problem of "the science" but a problem of an incomplete set of data.
In LTSpice you can predict circuit behaviour very precisely when you give the full set of data needed for that prediction. Of course when you just give the capacitance of a capacitor and not the full set of parasitics it gets mushy.

As someone who cycles regularly the answer is 'which forecast'? Different services often have significantly divergent forecasts for the same region. I learned long ago to rely on live webcams and weather radar.
