The Experiment

The Pictures

Orientational turbulence. Each line is a wall separating domains where the molecules have different orientations:

Orientational turbulence. Each line is a wall separating domains where the molecules have different orientations.

When the rotary motion of one plate is stopped, the turbulent state melts in a similar way as it was constituted of ice blocks melting in liquid water:

The remaining droplets serve as seeds for a new starting shear motion: Single domains will disappear but double ones will grow with their characteristic shape:

Between crossed polarizers, the differently oriented domains are made visible:

Between crossed polarizers, the differently oriented domains are made visible: a) without polarizers
a) without polarizers

Between crossed polarizers, the differently oriented domains are made visible: b) with polarizers
b) with polarizers
