en.wikipedia.org The dispersion relations show conics of the free-electron energy dispersion parabolas for all possible reciprocal lattice vectors.
en.wikipedia.org For certain fossils in paleontology, understanding conic sections can help understand the three-dimensional shape of certain organisms.
en.wikipedia.org Consequently, spiric sections are fourth-order (quartic) plane curves, whereas the conic sections are second-order (quadratic) plane curves.
