Squaring the circle

Is there a bijection of the plane sending every circle to a square?

One thought on “Squaring the circle

  1. Consider an infinite family of circles such that their pairwise intersection is a single point x, as in the construction of the hawaiian earring. If such a bijection existed, it would have to send this family to an infinite family of squares that pairwise intersect in a single point, which is clearly impossible.
