Log 43 responds to the many geometries seen in contemporary forms with “The Issue of Geometry,” a special section guest edited by architectural designer and educator Cameron Wu. Some 25 years after the digital revolution of the ’90s, Wu asks, “If we are now armed with a more mature understanding of instrumental design tools, how do we reanimate geometry as a design protagonist rather than a mere design enabler or incidental outcome?” The architects’ responses range from Peter Carl’s interest in rhythm to Iman Fayyad’s perspectival anomalies; from Wes Jones’s reassessment of the many relationships of geometry and architecture to Patrik Schumacher’s advocating for tectonism; from Andrew Witt’s concept of “grayboxing” to George L. Legendre’s form haiku. Wu also offers geometric analyses of five recent buildings, and artist Olafur Eliasson, architect Preston Scott Cohen, and architect Henry N. Cobb talk about their advanced uses of geometry. Log 43 also features essays on architecture’s withdrawal from and engagement with architectural austerity, the architecture of crypto mining, and Miesian materiality, as well as a conversation with Japanese architect Hiromi Fujii.
