A circle is a simple shape of Euclidean geometry consisting of those points in a plane that are equidistant from a given point, the centre. The distance between any of the points and the centre is called the radius.
Circles are simple closed curves which divide the plane into two regions: an interior and an exterior. In everyday use, the term "circle" may be used interchangeably to refer to either the boundary of the figure, or to the whole figure including its interior; in strict technical usage, the circle is the former and the latter is called a disk.
A circle can be defined as the curve traced out by a point that moves so that its distance from a given point is constant.
A circle may also be defined as a special ellipse in which the two foci are coincident and the eccentricity is 0. Circles are conic sections attained when a right circular cone is intersected by a plane perpendicular to the axis of the cone.
A circle's diameter is the length of a line segment whose endpoints lie on the circle and which passes through the centre. This is the largest distance between any two points on the circle. The diameter of a circle is twice the radius, or distance from the centre to the circle's boundary. The terms "diameter" and "radius" also refer to the line segments which fit these descriptions. The circumference is the distance around the outside of a circle.
Ludovico Einaudi OMRI (Italian pronunciation: [ludoˈviːko eiˈnaudi]) (born 23 November 1955 in Turin, Piedmont) is an Italian pianist and composer.
Einaudi was born in Turin, Italy. His mother played to him on the piano as a child. He began his musical training at the Conservatorio Verdi in Milan, gaining a diploma in composition in 1982. That same year, he studied with Luciano Berio and gained a scholarship to the Tanglewood Music Festival.
After studying at the Conservatory in Milan, and subsequently with Berio, he spent several years composing in traditional forms. In the mid-1980s he began to search for a more personal expression in a series of works for dance and multimedia, and later for piano. His music is ambient, meditative and often introspective, drawing on minimalism, world music, and contemporary pop. He has made a significant impact in the film world, with four international awards to his name.[citation needed]
His father, Giulio Einaudi, was a publisher, and his grandfather, Luigi Einaudi, was President of Italy between 1948 and 1955. He currently resides on a vineyard in the Italian region of Piedmont.
