The Annual Theory Meetings ("Christmas Meetings") started in 1961 and have been held every year since (with the possible exception of two years), previously at the Rutherford Appleton Laboratory and more recently at Durham.
This year, accommodation is in Collingwood College, and the lectures are in the new
Wolfendale Lecture Theatre, Calman Learning Centre on the University's Science Site.
Note that 15 or 30 minute question and discussion periods are scheduled after each talk
