SUMS: Poladian -- A geometric journey: Periodic geometry from art to biology

Speaker: Leon Poladian

Repeating patterns are very popular in art, from the mosaics of the Alhambra in Spain to
the mind-boggling designs of M.  C.  Escher.  Periodic structures also occur in nature
and cause stunning iridescent colours such as those on peacocks, beetles and butterflies
when these patterns are the same size as wavelengths of light.  This talk is an
abbreviated repeat of a recent Sydney Science Forum public talk.
