The author defines a ``loose-covering'' of \(\mathbb{R}^2\) by circles \(C_i\), that is each point \(x\in \mathbb{R}^2\) lies in some \(C_i\), but at most in the interior of two of the \(C_i\), and the center of a circle is not contained in the interior of any other circle. He then gives an example of such a ``loose- covering'' by unit circles deriving
