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.

More statistics -- from Hiawatha

As the author of this poem owes a debt to Henry Wadsworth Longfellow, I too owe Greg Coxson -- who showed the poem to me.

Hiawatha Designs an Experiment   by Maurice Kendall

Hiawatha, mighty hunter
He could shoot ten arrows upwards
Shoot them with such strength and swiftness
That the last had left the bowstring
Ere the first to earth descended.
This was commonly regarded
As a feat of skill and cunning.
