A 'c' change
If you should search for knowledge
To answer the riddle of your self
All the books found on every library shelf
Might not relieve your puzzle a smidge
Because ‘h’ is the difference of self from shelf
Search within and you’ll see without eyes.
Things happen in a test tube
That we can easily observe and explain
But anywhere outside of it
It’s not quite the same
That’s because it’s out in the open
Where there’s less control and closure.
Some advise taking only two steps
Once into and once out of water
Supposedly while you’re watching
Perpendicular to a flowing stream
So firstly you get your feet wet
And then you get them dry.
Or you take the opposite length
Over the adjacent length
Then every measured distance
Makes each tangent different
But if trigonometry was used at Pisa
That’s not why the place is famous.
So if a princess was in a tower
And let’s assume she was a prisoner
At least she should have a window
Because horizons offer a fine view
Then the next time the witch calls her
Rupunzel throws down her chair.
