evolvent

It is the locus of the centers of all the circles which are osculatory to the given curve or evolvent.

It is important to note that an evolvent is defined as a principle which behaves as the material cause for the evolution of another principle.

For example, intellect while itself created out of Prakriti causes the evolution of ego-sense or ahamkara and is therefore an evolvent.

The shape of the front of the rotating spiral wave in the distance from the centre of rotation is close to the evolvent of the circumference - the boundaries of its core.

In the differential geometry of curves, an involute (also known as evolvent) is a curve obtained from another given curve by attaching an imaginary taut string to the given curve and tracing its free end as it is wound onto that given curve; or in reverse, unwound.
