Once many decades ago I was standing under a little
tree with either apples or blossoms on it, can't remember.
But it was during a solar eclipse. The amazing thing was
the shadow under the tree during the partial eclipse part.
The images of the leaves and blossoms became so
detailed it was like a painting. This is because the source
of the light was closer to a pin-point than normal.
Now today I was looking at blurry shadows off the deck
below of me holding weights over my head. When
I moved the barbells closer to my head I noticed
something I've seen before, but made a mental note
of it. When you move two objects with blurry shadows
due to a large light source, move the 2 objects
fairly close together, then a new adjoining
shadow forms between them in the shadow, kind
of like a connector. I'm sure there's a good reason
for this, but I can't envision it well. I guess when
the 2 objects get close together, the light from the
sun is doing a "slit" experiment sort of, but a wide
slit. And then you get the darker region in the middle
