It starts with counting . . .

Mathematical imagery is one of the many features I enjoy in the work of Canadian environmental scientist and poet Madhur Anand.  Here is a sample from her new collection (A New Index for Predicting Catastrophes).
 
Background:  In an experiment designed to test the truth of a given statement 
(often called the null hypothesis), a Type I error occurs if the experiment results in a true hypothesis 
being rejected (a "false positive") and a Type II error occurs if a false hypothesis is accepted. 

Type One Error     by Madhur Anand

I avoid news, talk to strangers, walk around the block
a thousand times and toss nickels for random samples.
I still get a few false positives.  I'm fine.  It's good.

Caught in an infinite loop . . ..

Philadelphian Marion Cohen has been a mathematician since girlhood and a poet almost that long.  Besides her mathematics and writing, she teaches an interdisciplinary math-and-literature course at Arcadia University.  Here is a sample of Cohen's math poetry -- which imaginatively links mathematics to everyday life, sort of -- from her recent collection, Parables for a Rainy Day (Green Fuse Press, 2013).
