through mathematical modeling and experimentation. Our models are based
on standard ideas of center of gravity, center of buoyancy, and
Archimedes’ Principle extended to the notion of a two fluid scenario. We
investigate floating shapes with two-dimensional constant cross sections
and identify a potential energy landscape that helps identify stable and unstable
floating orientations. We compare our analyses and computations to experiments
on floating objects designed and created through 3D printing.
