I have a simple geometry question hopefully I'm posting this in the right forum. I want to draw a simple logarithmic spiral using only compass and ruler or any other simple mechanical means. The requirement is that each spiral must be halfway from the center to the next spiral. Is there a simple method for drawing this?(adsbygoogle = window.adsbygoogle || []).push({});

something like the one in this picture.
