So you think wire conductors in cables are directional? Think again...


Here is a very relevant discussion among physicists about the directionality...the way signal and electrons should flow... based on conductor orientation. Some esoteric, high-end manufacturers say they listen to each conductor to see which way the signal should flow for the best audio quality.

Read this discussion. Will it make you rethink what you’re being told and sold?

Why human use stick unlike bats and dolphins?

Because they take advantage of their hands and because they walk on solid earth they dont swim or fly...

To some very limited degree. If a blind person can ride a bike on a crowd street then there may be something to it. I am sure blind people mental capacity can develop to compensate for the lost of vision, but to say human can have the ability as bats which is quite inaccurate.

Because they take advantage of their hands and because they walk on solid earth they dont swim or fly...
Because they need to use the stick to know if there are obstacles on their path.  They can't do that with sound echo.
I do recall some circumstances where people claim to have cured their cancer with their mind, but there are on a few reported cases.
The miraculous healing of Bruno Groning are so well documented   that this 3 hours videos will blow your mind...

It is a bit difficult here to establish fraud....Try it.... 😊 Good luck....

Hey maybe you can start a business curing people with cancer using their mind.  Can make a lot of money.  Win a Nobel Prize too.
