Noted in the poem “The Paper of My Enemy Has Been Retracted,” Andrew Gelman, Statistical Modeling, Causal Inference, and Social Science, from which I outtake the relevant partial stanza:

His sensibility and its hair-like filaments,
His delicate, quivering sensibility is now as one

A volume graced by the descriptive rubric
‘The simplex method visits all 2d vertices.’
