Abstract: A Borel (or even analytic) subring of $\mathbb R$ either has Hausdorff dimension

or is all of $\mathbb R$ . Extensions of the method of proof yield (among other things) that any analytic subring of $\mathbb C$ having positive Hausdorff dimension is equal to either $\mathbb R$ or $\mathbb C$ .
