A Seussian Lesson in Perspective

As we saw last Wednesday, balls in parks
*can* be used to teach parabolic arcs. 

 

But even more so - if such is your objective -
they can be used to demonstrate a bit of art perspective. 

For if one places a clever ball in front of one's human eyes,
One can make distant objects small, rather like a portable disguise!

So to continue this Seussian tale of educative learning,
I ask aloud where the Spire has gone, my voice all full of yearning.
But while I question, puzzle and ponder,
Oh look! The Maestro moves and something's seen off yonder. 

The ball is gone; the Spire's in range, and we've learned lots - for instance!
We've seen that seeming size can change, thanks to the art of relative distance.

So now we're homeward bound, and as we explore,
We're thankful for the world around and learning galore.
