It gets tiresome to have your 42 years of experience ignored over and over again.
It gets tiresome to have 20 years of education supposed to make the difference between kindergarten behaviors and those of a friendly conversation between adults ignored over and over again.
It gets tiresome to see millions years of civilisation trying to transform 'homo erectus' in gentlemen ignored over and over again.

The kindness and elegance of our behaviors seem to me more important qualities than the accuracy of the opinions we can have as a result of the experiences of both good and bad electrical contacts we all have experienced in our lives.

BTW: Sorry about your house's problems. Hope you will soon find a solution .

No there is no policy to my benefit, the current owner bought the house with an unprobated will involving the property and wants me to assume the same risk. Probate takes 6 months or more and I'm not interested, there are other houses. I have not bought the house and I have no damages, I can recover all my earnest money and move on. Living in temp housing with all my stuff in storage sucks that's all.

At least you didn't unpack!!!

It's even worse!

It only applies to the speed of light in a vacuum (is there a true vacuum?) and not through any differing gravitationally warped SpaceTime (good luck finding that!)!

We're screwed!

😀

Ya... I already pointed out lights only constant is the top speed. Electro stuff in space can slow down light. It also does weird stuff passing through some mediums (including speed). But gravity itself does not change light speed, just direction.
 
And now for a musical interlude

Hi Tryphon,

It gets tiresome to have your 42 years of experience ignored over and over again. 40yr. ago we hand tested IC's by the 10's of thousands and these contact issues were never a major problem. We trim amplifiers to uV offsets and -140dB CMRR/PSRR (8000 or more on a wafer) do you you think we stop every few hundred and clean the probes?

I did not ignore it. I said, I havent heard directional affects in cables. If such exists, there are contact or bad soldering or shield/ground methods or some other asymmetrical issues with connections/connectors. Not from just the wire.

I dunno, will buy me the first Americano if we're going to start down that path? Sure why not. 🙂

If we start talking about black holes I might have to go on the wild side, and you might be tempted to throw your coffee on me so plz order iced.
It's what red shift is.
As light drops into a gravity well like earth, there is a blue shift because it cannot go any faster, so it picks up energy.

Getting back to the wire loop, hams often use homemade ladderline with high characteristic impedance. For instance I saw one made from copper wire with infrequent 6" spacers. I don't see a big jump from a shorted meter of this to a wire loop. The classic solution of a sudden application of a battery is a current stairway to heaven or until the wire explodes.

As we have shown the TL solution is a piecewise fit exactly to the LRC solution for short lengths. It's all about storing energy in the fields and both solutions have to be the same.
 
Before transfering ourselfs toward outer space, can we agree to deside -unless solid measuring data is provided- burying the cable directionality issue for good?

yes, as a literal interpretation for a coax wire/cable....

Some audio cables are not just a coax. Some are two wires plus a shield and the shield may be grounded at one end only. And then there are what might be called defects in mfr... bad solder joints, for example. Which is common with 'custom', hand made audio mfr.

When someone raises such a controversial issue, I would expect that he would have placed upfront the con founder of not symmetric end construction or termination of a particular cable he is describing.

And then there are what might be called defects in mfr... bad solder joints, for example. Which is common with 'custom', hand made audio mfr.

Same as above. End asymmetry does not make the scenario of (audio, usb) cables are directional.

Cable end comes first among the details to be investigated when any test set-up might be used to examine the scenario.
