Feeling Poetic

The one poem that I had to learn by heart in school and still remember in its entirety is this:

Der Logarithmus
von A zur Basis B
ist die Zahl,
mit der man B
potenzieren muss,
um A zu erhalten.

(The logarithm
of a number A
to base B
is the exponent
to which B
must be raised
to produce A.)
