I'm the convener of the "Q Seminars", which is a group of staff, students and exstudents, who meet fortnightly over dinner, to share their enjoyment of mathematics in a relaxed and friendly environment. Each year is devoted to a special theme:  1998: Galois Theory
 1999: Probability and Measure Theory
 2000: the Riemann Hypothesis
 2001: the Fundamental Theorem of Algebra
 2002: the Continuum Hypothesis
 2003: Group Representations
 2004: Celestial Mechanics
 2005: Nonstandard Analysis
 2006: Hilbert's Nullstellensatz
 2007: Quaternions and Octonions
 2008: Integer Partitions
 2009: The Mathematics of Voting
 2010: Google PageRank and the mathematics of the internet
 2011: Combinatorics of words
 2012: Arnold’s “Dynamics, Statistics and Projective Geometry of Galois fields”
