With new eyes, things become active and smart.
Ludger Hovestadt led the chair of Computer Aided Architectural Design (CAAD) at ETH Zürich for over two decades. His ten-volume On Digital Architecture is less a software manual than a treatise on how digital culture changes the very objects of architecture — from singular things to numerical, generic, alive structures.
Hovestadt's design studio — where the numerical thinking lands.

caad.arch.ethz.ch ↗Hovestadt's ten books sit inside a centuries-long canon: Vitruvius's ten books on the rational, Alberti's ten books on the real, and now Hovestadt's ten on the complex. Each rewrites architecture for a new mathematical scalarity.
The Applied Virtuality Book Series (Birkhäuser) holds Hovestadt's contribution. On Digital Architecture spans ten volumes, currently grouped into two collected editions on Xenotheka.

Ten Books on Architecture — the rational scalarity. Hovestadt's first ancestor.

Hovestadt reads architectural thinking through numerical structures — each level adds a different relation, a different way of articulating the world.
The reference is the Sun, not Nature, not Earth.
You can't improve by doing better.

youtube.com ↗One question worth carrying across the lectures: how do objects breathe?
I am not what I can DO. I am what I can THINK about.
I am not talking about technology, this distant thing which is definite. I am talking about techniques, which can become me. I incorporate techniques. I embody techniques.
