NUMBERS

Glancing at a column, my grandfather Max

Knew instantly what they’d add up to.

My grandfather Joe could play chess in his head
And once forced the ghost of Paul Morphy
To accept a draw. My brother at ten
Half invented calculus before finding out
Leibniz and Newton had beaten him to it.
Once, because I missed you greatly,
I discovered a way to square a circle
Which, unfortunately,  I have forgotten.
