When solving problems in mathematics, the constraints that are imposed on the solution often are helpful in solving it. As a simple example, if we are given the lengths of the two shorter sides in a scalene triangle, the problem becomes easily solvable if we know that the triangle is a right triangle.
Poets also often find constrains helpful in shaping their words into special meaning. For example, the rhythm and rhyme scheme of the poetry-pattern called a sonnet have led to many notable poems. In this blog, in earlier postings, we have celebrated the FIB -- a six line poem whose syllable-counts obey the Fibonacci numbers. A popular form of poetry for calling attention to a particular idea is an ACROSTIC poem -- a poem in which the first (or other) letters of each line spell out a word or phrase. Here is my sample: MATH POEMS HELP US SEE.

Here is a link to a statistics-acrostic poem posted in this blog back in 2014. And this link leads to a selection of mathy sonnets.
