The great wall...

One day while traveling down the knowledge road
Across the streams and rocks I strode
Some were large but most were small
And then I came upon the wall.

The height of it I could compute
It’s mass I knew was not minute
Of brick and mortar it was made
Each one upon the other laid

At first I tried to climb the wall
I’d slip and slide and then I’d fall
Then proceed to fume and cuss
That dreaded wall called calculus!
