Spheres and parallels

On 23 January 2013 I posted a latitude-longitude poem "Zero-Zero" by Elizabeth Bodien and today I offer another of her poems of celestial geometry, this one inspired by a painting by San Francisco artist Blazin.  Here, first, is Blazin's painting, followed by Bodien's poem -- both entitled "Midnight / Noon Along the Solar / Lunar Meridian." 

Because the mind circles an idea

Besides eight books of poetry and a memoir, California poet Lucille Lang Day has co-authored a textbook, How to Encourage Girls in Math and Science -- a book of activities for teachers and parents to encourage students from kindergarten through eighth grade.  Her close connection to mathematics and science is evident in the following poem.

Because     by Lucille Lang Day

My heart will beat two billion times
because Krishna plays his flute in the forest
because the planets trace elliptical orbits
because Krishna's skin is blue
because a moon will fly in a straight line forever
unless a planet snares it
the way a woman attracts a man with her gaze 

Lagrange points

The Italian-French mathematician Josef Lagrange discovered the existence of five special "Lagrange points" (aka Lagrangian points) in the vicinity of two orbiting bodies where a third, smaller body can orbit at a fixed distance from the larger ones. More precisely, Lagrange Points mark positions where the gravitational pull of the two large bodies precisely cancels the centripetal acceleration required to rotate with them. Poet Catherine Daly considers these points in a poem:
