In 1978 the Royal Institution Christmas Lectures featured for the
first time a talk on Mathematics. Presented by E. Christopher Zeeman
and entitled "Mathematics Into Pictures", it generated such a wave
of interest that a Mathematics Masterclass series was set up.
Since then there have been many regional groups running
master classes. You can find out more about these from the RI
The format of a mathematics masterclass is usually to have
2 1/2 hours on a Saturday morning, with a break in the middle
for squash and biscuits.
Several of the Mathematics Talks that Colin gives can be done
in this format. The Juggling Talk is one, but others are
Maths In A Twist, The Distance To The Moon, The Doodle Theorem, and
the talk with the short title "NOOG", but with the longer
title "NIM, Officers, and Other Games".
