Why circle and square? There is really no good reason, except that these are simple, classic shapes beloved by mathematicians, artists, and children. The circle appears everywhere: in the sky, as the face of the sun and moon; in children’s drawings as a primitive shape to which eyes, mouth, nose, ears, arms and legs are later added; in philosophy and Greek science, as the perfect form; in mathematics, as one of the principal shapes treated in Euclid’s elements; in art, as an element of composition; in music, as the circle of fifths governing harmonic movement. A good starting point for a blog whose purpose is at yet undefined. (This is an experiment).
