"Mathematics is a large reasons why certain poems have a rhythmic quality and cadence. For example, stanzas have a certain number of lines, and lines contain a certain number of syllables. This influences how one reads or recites a poem, since the numerical features of a poem change how it sounds." The American poet Ezra Pound expressed very well the resonances between poetry and mathematics in The Spirit of Romance (1910): "Poetry is a sort of inspired mathematics, which gives us equations, not for abstract figures, triangles, spheres and the like, but equations for the human emotions." However, the question is: Is poetry a mathematical? How mathematics and literature are similar? Why are poems important in mathematics? This haiku collection explores mathematics as poetry.
