Re: LOGO-L> natural circle, the never ending story

Spot on Erich,

This is the identical equivalent of driving a floor turtle with 
differential inputs to the two motors. And, of course, it implies the need 
for a physical operation and hence the expenditure of energy to maintain 
the circular movement - a point noted by a chap called Newton.

By the way, if energy is expended, can the story be without end? 

Your second point I never disputed.
A sample of a sinusoid of appropriate frequency is a good enough 
approximation to reproduce that sinusoid digitally. It is not, however, a 
sinusoid any more.
