Sedimentation is the settling under the action of gravity of particles suspended in a viscous fluid, a process that is influenced by many physical effects. Here the authors investigate the sedimentation of an achiral particle, a rigid U-shaped disk, in a regime where inertia is negligible and find evidence of chiral trajectories whose handedness is determined by the disk’s initial orientation rather than its shape.
