Abstract
Under certain experimental conditions, the angular velocity ascribed to the relative rotation of a bacterial flagellum has observed values which are given by the rotational quantization condition
ω =
m
h
̵
:
I
r
, where
I
r is the moment of inertia associated with the rigid rotating part of the flagellum and
m (the apparent rotational quantum number) has been observed to equal + 1, −1 and zero. It is conjectured that the biological design values for ω stem from an evolutionary antecedent of the bacteria, a protoform without flagellar filament development and viscous-dominated dynamics, in which the rigid part of a flagellum had rotated freely in accord with the quantization condition.
