The study of geometry is at least 2500 years old, and it is
within this field that the concept of mathematical proof - deductive
reasoning from a set of axioms - first arose. The lecture will present
four areas of geometry: Euclidean, non-Euclidean, projective geometry in
Renaissance art, and geometry of space-time inside a black hole.

Tea, coffee and biscuits will be served in room 409 before the lecture,
at 15.30.
