Well-known and beloved writer Ursula Le Guin (1929-2018) died last month -- at the age of 88. Although best known for her fiction, Le Guin also was a poet -- and I include samples of her poetic work (and links) below.
An adaptation for the stage of Le Guin's novel, The Lathe of Heaven, is currently in performance (until March 11) at the Spooky Action Theater as part of Washington, DC's Women's Voices Theater Festival. I had the privilege of attending last Saturday's performance -- and liked it a lot.
Le Guin's poetry is not substantially mathematical, but I include a couple of verses below that each contain a mathy term or two . . .
The verse above is found here along with links to other Le Guin poems. And, below, a brief poem found in Le Guin's The Left Hand of Darkness, (Ace Science Fiction, 2000, page 233).
Light is the left hand of darkness
and darkness the right hand of light.
Two are one, life and death, lying
together like lovers in kemmer,
like hands joined together,
like the end and the way.
