This fourth book in the Nexus series offers papers that further broaden the horizons of studies in architecture and mathematics. Over the years, Nexus has truly shown itself to have created a just that: a nexus between disciplines, between "languages", between cultures. This new collection of papers carries on the splendid interdisciplinary variety that has characterized the previous three volumes: architects, historians, theoreticians, mathematicians and scientists from Australia, Canada, China, France, Italy, Portugal, Turkey, the United Kingdom and the United States, present papers on subjects as diverse as shape grammars, amphitheaters, neo-Platonism, Stonehenge, scientific rationalism, Vastu geometry, cubic equations and systems of proportion. Western architecture of almost every period is examined: Egyptian, Roman, medieval, Renaissance, Baroque, Enlightenment, twentieth-century, as is the architecture of China, India and Islam. Containing such diversity in a single volume is quite a feat; that is, it is a volume as rich as the Nexus conferences themselves.
