Funniest snake oil theories

Also skill isn't hard to find, at least not in Germany. Of course a bunch of bearded hipsters seem to have invented craftmanship a couple of years ago but there are loads of trained craftspeople with really high skills.
One of the standard tasks we had to do in machinists training, when we learned how to use files was to file a square hole into a steel plate and then file a square piece that exactly fits into there. Exactly means it must be able to be pushed out by two thumbs and held against a light source no gap is to be visible. Standard job.

It might be true that people with the skill is easy to find in Germany. Lots of good products come out of Germany. The square you are talking about is very general skill, the sliding fit is easily accomplished by machine. But there are situations when you start having strict tolerance requirements, the human skill is more important than most can imagine. At least here, such people with such patience and dedication is hard to find across multiple industries.

I am not dissing 'conventional' theory, but I am suggesting that it does not fully describe the likes of BQP, my filters, and indeed the effects of power cables.
You are asking for new physics in order to explain snake oil products and snake oil ideas.

So let's talk physics....how does a ferrite bead filter work, I mean really work, not just overview description, and what secondary effects are to be expected ?.
The quick answer is that if you could understand the answer you would not need to ask the question. A slightly slower answer is that it adds impedance to the conductor threaded through it over a limited frequency range. Secondary effects may include distortion if too much current is present. Given knowledge of the ferrite properties you could probably model it using Comsol Multiphysics.

Only the fool laughs at that which he does not perceive or understand.
The wise man can laugh at that which he understands only too well.

In this fully extremely automated world, the devices that require extreme precision are still refined by the skilled hand.
So that is why we need hand made mains cables?

Absolutely. Hand labour is way more prone to error and tolerances are much wider (how do I properly say this in English?). So there's a greater difference between each cable then with completely (and properly) machine made ones.
This finally opens the gates for listening for differences in mains cables as there are slight differences.
Probably none that matter, but still.

Sure, and according to the ferrite formulation.

Ok, using which parameters ?, and thanks, I will give it a look.
Ferrite should not affect the sound of a system seems to be engineering opinion, but practice shows this not to be the case.

Yes, when the wise man really understands....do any of us know how magnetics really works.

I heard that the reason why we don't fall through floors and walls is because of the magnetic fields surrounding atoms are repelling each other pushing against the atoms of our clothes/bodies. If you could suppress that magnetic field you could walk through walls.

So go ahead, please educate us all on how magnetism is generated, and how magnetic fields and strongly magnetic and weakly magnetic materials interact, don't forget all the magnetic classifications of materials.

I am not your teacher of physics. But if you are really interested, Feynmans Lectures on Physics are imho one of the best tutorials ever written. And they are sometimes entertaining as well🙂
