The distinctive properties of the logarithmic spiral which permit it to be used for lines of pitch of cams and non-circular wheels 38 are: (a) that the difference of radii vectores of the ends of equal arcs is constant; (b) the curve cuts radii vectores under a constant angle. For these reasons two equal logarithmic spirals may roll together with fixed poles and a fixed distance between the poles.

Euclid is not the father of geometry; he is the father of mathematical rigor. The Elements consist of twelve books, and the elementary geometry taught in the world's high schools corresponds, in one form or another, to the first four. Alas, the reason why it should be taught is very often grossly misunderstood. The system of numeration adopted the Greeks is described later,1 but it was so clumsy that it rendered the scientific treatment of numbers much more difficult than that of geometry; hence Euclid commenced his mathematical course with plane geometry.
