The curvature of these parabolas is extrinsic.The enormous exponents make it evident that these units are far removed from our everyday experience. It would be absurd to tell somebody, “I'll call you back in 1.08×10 14 centimetres”, but it is a perfectly valid way of saying “one hour”.

A curvature unit alone defines a planar arm behavior, as it defines a change in the curvature level along a section of the arm as a function of time, with a zero value for the torsion associated with the arm. Coupling a curvature and a torsion unit, such that both of them refer to a common section of the arm, defines a 3D behavior.

curvature is to measure how quickly this unit tangent vector changes, so we compute kT0 1 (t)k= kh cos(t); sin(t)ik= 1 and kT0 2 (t)k= D ˇ 2 cos(ˇt=2); ˇ 2 sin(ˇt=2) E = ˇ 2: So our new measure of curvature still has the problem that it depends on how we parametrize our curves.

13.3 Arc length and curvature. Sometimes it is useful to compute the length of a curve in space; for example, if the curve represents the path of a moving object, the length of the curve between two points may be the distance traveled by the object between two times.
