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 magnetic fields is used as a reference instead. In the case of the Sun, even this criterion fails (because its magnetosphere is very complex and does not really rotate in a steady fashion), and an agreed-upon value for the rotation of its equator is used instead. For "planetographic longitude", west longitudes (i.e., longitudes measured positively to the west) are used when the rotation is prograde, and east longitudes (i.e., longitudes measured positively to the east) when the rotation is retrograde. In simpler terms, imagine a distant, non-orbiting observer viewing a planet as it rotates. Also suppose that this observer is
