Nexus Network Journal 13,2, 2011 Architecture and Mathematics Nexus Network Journal Series, Vol. 13,2

The Summer 2011 (vol. 13 no. 2) issue of the Nexus Network Journal features eight papers that resulted from the eighth international, interdisciplinary conference entitled ?Nexus 2010: Relationships between Architecture and Mathematics, held in Porto, Portugal, in June 2010. This is the second issue of this volume that contains papers presented at the conference. In the spirit of interdisciplinarism that characterises the NNJ, the presentations range in time from the historical to the contemporary; in scale from the level of the individual building to urban design; in subject matter from pure architectural theory to building practice; and in themes from geometry and perspective to music. The aim of the NNJ is to provide a wide panorama of the relationships that exist between the disciplines of architecture and mathematics, and this issue captures those relationships in all their richness and variety.
