Continuing report ... re <<recurse>> ... builds memories
- one thing we do get to keep is our memories
- memories of ourselves, where we had been, who with, what's doing, etc, with family, friends, and opponents
- from the beginning, to the next beginning
I discover this day that my fat Jack is reasonably astute. perhaps more so than I.
I was puzzled w/r to the water lily / duck pond outside of my window at the farmer’s bed & breakfast, seeing water flowing endlessly in from somewhere and so we traced to the origin
Jack said, “dada, it runs by the twirly thing at the river” - I thought the Jack was talking about either a water wheel or an electrical pump mechanism.
Jay: does it use solar electricity?
Jack: no dada, it just runs without electricity.
Jay: no way. It is a question of potential energy of the higher height of the pond, and the lower level of the river. Need kinetic energy to bridge that potential energy gap by the laws of conservation of energy (I was deliberately talking above my 8-years young brain)
Jack: dada, the twirly thing does not use electricity make the water flow up.
Jay: no way (I got you Jack. No way!)
Alas, I was wrong.
Here is the higher level pond ...
The small winding aqueduct through the neighbourhood that feeds the pond ...
The water from here, which is ~4 meters higher than the river, and I figured, look at the flow! There has got to be a pump going 24/7, even as the economic mathematics make no sense for such to feed a pond when there are only two ducks about and the water lilies are not in season.
Jack: dada, look, the whirly thing. I looked.
And the pipe connected to the twirly-thing guiding the water upward from the river below ...
I corrected myself. I explain to the Jack, see, Jack, they channeled the water from the broad river to the progressively narrowing side channel, speeding up the water flow, guiding the speeding water flow into a cul de sac w/ a deep hole at the end. The water twirls into the hole, loses potential energy from the increased kinetic energy, and then used that sped up kinetic energy to force the water into a sharply upward inclined pipe contraption … to gain potential energy. Are you getting all that, Jack?!
Jack: dada, I told you, the twirly thing, and it uses no electricity!
Jay: oh look, Jack, a bird!
Snowshoe, just imagine, there are people in this world wanting africa to say no to hi-speed rail, hospitals schools, nuclear reactors, and twirly things. Incredible :0)
Back story, Jack did not trace the flow ahead of me. He simply does not recall where he saw such a contraption, but remembers the schema.
Nice. |
