One Minute Wonders (piano) One Minute Wonders (piano) One Minute Wonders is the name given to a series of piano pieces by leading British composers, commissioned by the pianist Clive Williamson in association with the University of Surrey. The challenge, laid down to all contributing composers, was that submitted compositions had to last no longer than 60 seconds (although, in practice, several pieces exceeded the time limit). Contributing composers included Colin Matthews, John Woolrich, Julian Anderson, Matthew King, Tansy Davies, Steve Goss and Michael Finnissy. Many of the compositions were premiered at a concert at the University of Surrey in 2005. Anthony Payne, writing
Longitude of the periapsis Longitude of the periapsis In celestial mechanics, the longitude of the periapsis, also called longitude of the pericenter, of an orbiting body is the longitude (measured from the point of the vernal equinox) at which the periapsis (closest approach to the central body) would occur if the body's orbit inclination were zero. It is usually denoted "ϖ". For the motion of a planet around the Sun, this position is called longitude of perihelion ϖ, which is the sum of the longitude of the ascending node Ω, and the argument of perihelion ω. The longitude of periapsis is a compound angle,
