Stochastic

Not terribly familiar with the term but after a short hop over to wikipedia feel a bit more enlightened...and find that it is related to another word I think you've mentioned of import, sinusoidal, and both are related to a word near & dear to my heart which is resonance.

If you care to expand on the above I'm all ears, no pun intended.

One of the things that felt familiar to me when I learned about TTB listening to signals via rocks was previous reading about people who study the Schumann resonance. The echoes of lightning thunder bouncing around the atmosphere. The planet Earth's equivalence to whale song, one might say. Within that 7.8Hz range there's some variation as well as what I might now tentatively term "stochastic" noise (am I getting that usage properly, Trickfox?). A few of these amateurs have built very large receiving antennae to graph and track how the Schumann resonance changes over days, weeks, years. Some of them are concerned that we are artificially messing up a signal that is important to biological regulation.

splashing in a stream

Interesting story Trickfox, indeed.

And you know me. I get certain variations on other peoples themes and when I read about the "naked boys splashing in the stream" I thought immediately of Dr. Brown and his beloved Ohio river ... doing what he loved so much! I understand that he loved splashing in water! It was a lifelong passion for him.

Paul has an article about the young Townsend Brown splashing in a fountain when he was a little guy ..... he had stripped down to nothing ... escaped from his parents ... climbed into a fashionable park fountain and his escapes made the paper " TOWNSEND BROWN STARTLES STAID TERRACE."

I know this is wierd. But Trickfox, I responded to your transfer of the above story as if he had reached out, or over somehow and touched us all. Sometimes information transfers in the strangest of ways. Elizabeth
