There's real poetry in the real world. Science is the poetry of reality.
Poetry is a sort of inspired mathematics, which gives us equations, not for abstract figures, triangles, squares, and the like, but for the human emotions. If one has a mind which inclines to magic rather than science, one will prefer to speak of these equations as spells or incantations; it sounds more arcane, mysterious, recondite.
In science one tries to tell people, in such a way as to be understood by all, something that no one ever knew before. In poetry it is the opposite.
