There was a song that sprang to mind when I saw this challenge. It was popular in the sixties, and sung by Judy Collins.
I’ve looked at clouds from both sides now
From up and down, but still somehow
It’s clouds illusions I recall.
I really don’t know clouds at all.
Isn’t that the truth of it? What or whom we think we know, no matter how well we’ve studied and investigated, we find out we are only at the beginning of discovery. And more is of the ephemeral nature of clouds than we have any idea!
