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
Mercator 1569 world map that OE=OD, here approximately 54°. This is a measure of the rhumb line distance between the points on the sphere corresponding to A and B on the spherical Earth. Since each degree on the equator corresponds to 60 nautical miles the sailing distance is 3240 nautical miles for this example. If B is in the second quadrant with respect to A then the upper rose is used and if B is west of A then the longitude separation is simply reversed. Mercator also gives a refined method which is useful for small azimuths. The above method is explained in Legend
