*Watch Online/In person*: From the Ancient Greeks onwards, proportion and mathematics has been central to our ideas of form and beauty. This lecture looks at the famous golden ratio, from Greek temples to spiral seashells, discussing where it appears in nature (and why), and how people have tried to pinpoint the 'perfect' proportions of the human body and face. It will also look at why A4 paper is the shape it is and what Mrs Beeton has to do with the Rhind Papyrus.
