Bachelard, Gaston, The Poetics of Space, Beacon Press, 1994.

This renowned modern philosophical text, first published
in 1964, explores poetry's relationship to the
measurable, physical world.

Dove, Rita, The Poet's World, Library of Congress, 1995.

This publication actually consists of the texts of two
addresses that Dove made to the Library of Congress
while she was poet laureate. Her view of poetry's
overall significance and her goals as an individual
poet are emphasized.

Mlodinow, Leonard, Euclid's Window: The Story of Geometry from Parallel Lines to Hyperspace, Free Press, 2001.

Dove's poem assumes that its reader has a sense of
what geometry is about. In this book, Mlodinow
traces the history of geometry by discussing the major
figures who have shaped modern thought, giving
a funny, spry spin to a topic that students can sometimes
find dull and dense.
