Twice a year a new issue of the Journal of Humanistic Mathematics is published online; here is a link to the Table of Contests for the July, 2025 issue which I have recently enjoyed browsing. This issue contains a plentiful variety of poems and articles related to poetry. The term "Linear Poem" was a concept new to me -- found here in the article, "Introducing the Linear Poem" by Cristian Ramirez Rodriguez -- and I offer it below:
Linear Poems
Are poems where each line
increases or deceases by the same number of
words every single line, this number is the slope, m, and
the words in title are b (intercept); Here m is 3, b is 2.
The author goes on to tell how he has used this form with math students -- and he offers additional examples.
