Math lyrics -- Lehrer et al

Mathematicians with poetic tendency often use their word-talents to write song-lyrics rather than poems; a master of the song-writing art was/is Tom Lehrer.  As an undergraduate at Harvard in the 1940s,  Lehrer majored in mathematics; he is best known for songs he recorded in the 1950s and 1960s.  Here are Lehrer's lyrics for "The Derivative Song" -- written to be sung to the tune of "There'll Be Some Changes Made" (by Benton Overstreet, with original lyrics by Billy Higgins).

Poets who Count

For some poets, counting is part of the language of the poem. For others, counting determines the structure. Here are two poems of the former sort -- "Counting" by British poet Philip Larkin (1922-1985) and "Adding It Up" by New England poet Philip Booth (1925-2007) -- followed by opening stanzas of a poem for which counting is part of both content and structure:  "Millennium" by mathematician Peter Cameron .
