Lead and follow

In some types of partner dance, lead and follow are designations for the two dancers comprising a dance couple. In the case of mixed-sex couples, the male is traditionally the lead and the female is the follow. The lead is responsible for guiding the couple and initiating transitions to different dance steps and, in improvised dances, for choosing the dance steps to perform. The lead conveys his choices and direction to the follow through subtle physical and visual signals, thereby allowing the couple to be smoothly coordinated.

Theory

The amount of direction given by the lead depends on several factors, including dance style, social context of the dance, and experience and personalities of the dancers. Some partner dances (e.g., Lindy Hop) employ an open position that encourages improvisation by the follow. Others, such as Argentine Tango, involve a close embrace (or closed position) that requires the follow to strictly conform to the lead's direction.

Richie Havens

Richard Pierce "Richie" Havens (January 21, 1941 – April 22, 2013) was an American singer-songwriter and guitarist. His music encompassed elements of folk, soul, and rhythm and blues. He is best known for his intense and rhythmic guitar style (often in open tunings), soulful covers of pop and folk songs, and his opening performance at the 1969 Woodstock Festival.

Life and career

Early life

Born in Brooklyn, Havens was the eldest of nine children. He was of American Indian (Blackfoot) descent on his father's side, and of the British West Indies on his mother's. His grandfather was Blackfoot of the Montana/South Dakota area. Havens' grandfather and great-uncle joined Buffalo Bill's Wild West Show, got off in New York City and ended up on the Shinnecock Reservation in Long Island. There he got married then moved to Brooklyn.

As a youth in Bedford-Stuyvesant, Havens began organizing his neighborhood friends into street corner doo-wop groups and was performing with the McCrea Gospel Singers at age 16.

Vertex (graph theory)

In mathematics, and more specifically in graph theory, a vertex (plural vertices) or node is the fundamental unit of which graphs are formed: an undirected graph consists of a set of vertices and a set of edges (unordered pairs of vertices), while a directed graph consists of a set of vertices and a set of arcs (ordered pairs of vertices). In a diagram of a graph, a vertex is usually represented by a circle with a label, and an edge is represented by a line or arrow extending from one vertex to another.

From the point of view of graph theory, vertices are treated as featureless and indivisible objects, although they may have additional structure depending on the application from which the graph arises; for instance, a semantic network is a graph in which the vertices represent concepts or classes of objects.

The two vertices forming an edge are said to be the endpoints of this edge, and the edge is said to be incident to the vertices. A vertex w is said to be adjacent to another vertex v if the graph contains an edge (v,w). The neighborhood of a vertex v is an induced subgraph of the graph, formed by all vertices adjacent to v.

Vertex (geometry)

In geometry, a vertex (plural: vertices or vertexes) is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices.

Definition

Of an angle

The vertex of an angle is the point where two rays begin or meet, where two line segments join or meet, where two lines intersect (cross), or any appropriate combination of rays, segments and lines that result in two straight "sides" meeting at one place.

Of a polytope

A vertex is a corner point of a polygon, polyhedron, or other higher-dimensional polytope, formed by the intersection of edges, faces or facets of the object.

In a polygon, a vertex is called "convex" if the internal angle of the polygon, that is, the angle formed by the two edges at the vertex, with the polygon inside the angle, is less than π radians ( 180°, two right angles) ; otherwise, it is called "concave" or "reflex". More generally, a vertex of a polyhedron or polytope is convex if the intersection of the polyhedron or polytope with a sufficiently small sphere centered at the vertex is convex, and concave otherwise.
