Why physicists should seek the counsel of poets before making a Valentine promise:

Leibniz in Love

A poet without an ear

used an alphabet without letters

to write a poem without words.

(It's) the rhythm we overhear

within the color of birds-—

within the eyes of coquetters

within true love, my dear.

Love Debunks Leibniz

A poet without an ear

used an alphabet without letters

to write a poem without words.

(It's) the rhythm we overhear

recorded in the color of birds—

translated by mate-getters

left speechless every year.
