An ogive (/ˈoʊdʒaɪv/OH-jyv) is the roundly tapered end of a two-dimensional or three-dimensional object. See etymology, below, for origin of term.

In ballistics or aerodynamics, an ogive is a pointed, curved surface mainly used to form the approximately streamlined nose of a bullet or other projectile.

The traditional or secant ogive is a surface of revolution of the same curve that forms a Gothic arch; that is, a circular arc, of greater radius than the diameter of the cylindrical section ("shank"), is drawn from the edge of the shank until it intercepts the axis.

If this arc is drawn so that it meets the shank at zero angle (that is, the distance of the centre of the arc from the axis, plus the radius of the shank, equals the radius of the arc), then it is called a tangential or spitzer ogive. This is a very common ogive for high velocity (supersonic) rifle bullets.

The sharpness of this ogive is expressed by the ratio of its radius to the diameter of the cylinder; a value of one half being a hemispherical dome, and larger values being progressively more pointed. Values of 4 to 10 are commonly used in rifles, with 6 being the most common.

Éric Alfred Leslie Satie (pronounced: [eʁik sati]) (17 May 1866 – Paris, 1 July 1925; signed his name Erik Satie after 1884) was a French composer and pianist. Satie was a colourful figure in the early 20th century Parisian avant-garde. His work was a precursor to later artistic movements such as minimalism, repetitive music, and the Theatre of the Absurd.

An eccentric, Satie was introduced as a "gymnopedist" in 1887, shortly before writing his most famous compositions, the Gymnopédies. Later, he also referred to himself as a "phonometrician" (meaning "someone who measures sounds") preferring this designation to that of a "musician", after having been called "a clumsy but subtle technician" in a book on contemporary French composers published in 1911.

In addition to his body of music, Satie also left a remarkable set of writings, having contributed work for a range of publications, from the dadaist 391 to the American culture chronicle Vanity Fair. Although in later life he prided himself on always publishing his work under his own name, in the late nineteenth century he appears to have used pseudonyms such as Virginie Lebeau and François de Paule in some of his published writings.

William Orbit (born William Mark Wainwright, 15 December 1956) is an English musician, composer and record producer, perhaps best known to most for his work on Madonna's album Ray of Light. He has won three Grammy Awards for his work with Madonna. He produced 13 by Blur and remixed some of the songs on the album.

William Orbit was born William Wainwright in London's East End in 1956. His mother, of Italian and Swedish descent, and his father, from Yorkshire, were both schoolteachers.

He does not have a formal education, having left school at 15 and being entirely self taught. Aged 16, and living in a squat in Norwich and working as a strawberry picker in the summer, he started to devote himself to guitar playing.

Living in squats around Europe and working at various jobs, hotel kitchen worker, motorbike messenger, at a ladies shoes factory, as an accounts clerk (in the days before computers), a night shift worker at the old Heineken Brewery in Amsterdam, junior draftsman at a North Sea oil rig design company (he was 'creative' with his CV') and so on.
