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 with part of it being measured in the plane of reference and the rest being measured in the plane of the orbit. Likewise, any angle derived from the longitude of periapsis (e.g., mean longitude and true longitude) will also be compound. Sometimes, the term "longitude of periapsis" is used to refer to "ω", the angle between the ascending node and the periapsis. That usage of the term is especially common in discussions of binary stars and exoplanets. However, the angle ω is less ambiguously known as the argument of periapsis. "ϖ" is the sum of the longitude of ascending node
