o.O Ya know? I have never really thought about this and took "lift" for granted. I think what the brains need to do is take a page from one of the techs that was installing a new communications system in the Comm Center many moons ago. I asked him how something worked and he looked at me and said "PFM" (Pure Fucking Magic). I think this fits perfectly with this scenario.  |

A prime example of overthinking. We started with a theorem, tested it, saw that it was correct, then tested more and more to optimize and fine tune, in a universally-proven way, does it really matter?There is more air pressure on the bottom of the wing and less at the top. more push one one side than the other moves the wing in the direction of the lower air pressure.

Airplanes fly because of treadmills, everybody knows that.

I can die in peace without ever solving that mystery. Here's something to think about: I saw a house finch stuff herself at the feeder. Then she sat on the ground away from the feeder area for a long time. I think she weighed too much to take off! So weight is a factor in lift. Not exactly breaking news!  |

I had a Zebra Finch, he lived to 12-14, which is about 150 people years. He wore out at least 4 mates, siring at least 15 offspring. And up until the day he passed, the one thing he always did was splash in the water dish right after I put new water in, happy as a clam in mud.

I looked up that bird. I see it is a native of Australia. The house finch I was watching was just a visitor to my backyard when we lived in SLC. Here in Idaho, I have a birdbath and a heater to keep it from freezing in winter. Birds love to wallow in it. Such fun to watch!
