Ok, with all the responses, I had to read it. It was painful, but like most, I got the gist. And I will say that I have always noticed 32768 Hz referenced in electronics documents. I never thought much of it as I saw 32768 referenced in any binary based system. I found it interesting that it has "Magical" properties. Tesla would be proud of all of us for noticing `,~)
Thanks to those that posted it and those that elaborated on it as well. It's good to know that Crystal Hippies were actually right about magical crystals and it is supported by science.

Reminds me of a harsh joke I picked up in the 70s (that has MANY exceptions): How do you tell the difference between a computer salesman and a car salesman? A car salesman knows when he/she is lying. (Hmm. ChatGPT will slot right in for the current century. But maybe "perceives" would be better.)
