That the speed of light is a constant is one of the most important facts about space and time in special relativity. That fact gets expressed geometrically in spacetime geometry through the existence of light cones, or, as it is sometimes said, the "light cone structure" of spacetime. One interesting building block shape that self-organizes into precise structures is the cone. Certain amphiphilic nanoparticles (), molecules (4, 10, 11), and some virus capsomers (12, 13) that self-assemble into precise structures can, to first approximation, be modeled as cone-shaped particles associating via weak attractive interactions.Cone-in-cone is a peculiar structure consisting of usually vertical nests of cones, one inside another, that are found either in thin beds or at the edges of large concretions. Some cones are less than an inch tall, and others are as much as 10 inches high. They have a ribbed or scaly appearance. To this end, we remark the relationship between both notions: a Lorentz-Finsler metric uniquely determines a cone structure, and a cone structure uniquely defines a class of Lorentz-Finsler metrics whose lightlike pregeodesics coincide with the cone geodesics of the cone structure (Theorem 1).Abstract. We investigate the existence of hyperbolic, spherical or Euclidean structure on cone-manifolds whose underlying space is the three-dimensional sphere and singular set is a given two-bridge knot. For two-bridge knots with not more than 7 crossings we present trigonometrical identities involving the lengths of singular geodesics and ...A conifer cone or pinecone is a seed-bearing organ on gymnosperm plants.
