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 then the longitude at a point would be equal to the angle between a vertical north–south plane through that point and the plane of the Greenwich meridian. Everywhere on Earth the vertical north–south plane would contain the Earth's axis. But the Earth is not radially homogeneous and has rugged terrain, which affect gravity and so can shift the vertical plane away from the Earth's axis. The vertical north–south plane still intersects the plane of the Greenwich meridian at some angle; that angle is the astronomical longitude, calculated from star observations. The longitude shown on maps and GPS devices is the
