Rehinging Bi-Flagellar Locomotion in a Viscous Fluid

[SaverioIV]

Same as optimal elastic flagellum response: the passage of a wave is not time-reversible. ;)

here i see that its a two armed swimmer and the way it is flapping its arms forward is not the same as it flaps them backward so the motion of arms is time irreversible and hence it is able to propel forward.
