This lecture is part of a series of public lectures organised by Computing Science and Mathematics, University of Stirling.
The golden ratio is a special number approximately equal to 1.618 which appears many times in geometry, art, nature and other areas. In this talk I will explain where it comes from, look at where it appears in the real world, whether it is the most irrational number and how it relates to witchcraft.
All are welcome to attend this free event, there is no need to book a place.
