Autorenportrait

Professor Brian R Martin, Emeritus, Department of Physics & Astronomy, University College London, UK Brian Martin was a full-time member of staff of the Department of Physics & Astronomy at UCL from 1968 to 1995, including a decade from 1994 to 2004 as Head of the Department. He retired in 2005 and now holds the title of Emeritus Professor of Physics. He has extensive experience of teaching undergraduate mathematics classes at all levels and experience of other universities via external examining for first degrees at Imperial College and Royal Holloway College London. He was also the external member of the General Board of the Department of Physics at Cambridge University that reviewed the whole academic programme of that department, including teaching. Dr Graham Shaw, School of Physics & Astronomy, The University of Manchester, UK Graham Shaw (http://www.hep.man.ac.uk/u/graham/) was a full-time member of staff of the School of Physics & Astronomy at Manchester University until September 2009. He continued to teach part-time until September 2012 and currently holds an honorary position in the department. He has extensive experience of teaching undergraduate physics and the associated mathematics and was a member of the school's Teaching Committee and Course Director of the Honours School of Mathematics and Physics for many years.
