Cone

A cone is a basic geometrical shape: see cone (solid). Several things have also been called "cones" on account of their shape:

• A volcanic cone is a mountain formed by material ejected from a volcanic vent.
• In relativity, the light cone of an event consists of all spacetime events that can interact with it.
• The scaly fruit-like reproductive bodies of certain plants, especially conifers and cycads, are called cones: see conifer cones.
• In vertebrate anatomy, a cone cell is a type of light-sensitive cell found along with rods in the retina of the eye.
• In ceramics manufacture, a pyrometric cone is a conical or pyramidal mineral stick that is used to gauge the temperature of an oven.
• An ice cream cone is a container for ice cream, shaped like an inverted cone open at its top. It is often made of edible pastry.
• A traffic cone is a brightly colored cone-shaped plastic object commonly used as a temporary traffic barrier or warning sign.
• In basketball, a cone is a player who is so slow and unskilled that he can be dribbled around as if he was a traffic cone.
• Cone is the bassist for the Canadian band Sum 41.
• Fairfax M. Cone was an American advertising executive sometimes called the "father of modern advertising".
• To 'smoke a cone', using a bong and a Conepiece is a term used by Marijuana smokers.

The word cone and its derivatives also have several specialized meanings in mathematics:

• In geometry,
• cone (geometry)
• cone (surface)
• cone (solid)
• Also in geometry, the cone of an arbitrary set $X$ means the union of all line segments connecting a fixed point to points of $X$. For example, this coning operation will turn a triangle into a tetrahedron.
• In topology, too, coning may be applied to a topological space, e.g. to define the barycentric subdivision of a cell complex; see cone (topology).
• In linear algebra, the convex cone of a set of vectors consists of all linear combinations of those vectors with non-negative coefficients.
• In graph theory, a cone graph is a graph with a universal vertex (a vertex that is connected to all others vertices).
• In descriptive geometry, "conical projection" is another name for the perspective projection.
• In cartography, however, a conical projection maps the spherical surface of the Earth to a conical surface, that is then unrolled onto a plane.
• A conic section is any curve obtained by cutting the surface of a cone (more precisely, a conical surface) by an arbitrary plane.

Shape: In geometry, two objects are of the same shape if one can be transformed to another (ignoring color) by dilating (that is, by multiplying all distances by the same factor) and then, if necessary, rotating and translating. Dilation changes the size but not the shape; rotation and translation preserv...

Cone (solid): In common usage and elementary geometry, a cone (Greek: κώνος) is a solid object obtained by rotating a right triangle around one of its two short sides, the cone's axis. The disk swept by the other short side is called the base, and the endpoint of the axis which is not on...
