Sasaki proposes an engineering revolution - an overturning of traditional empirical methods in favor of new kinds of shape analysis that use the principles of evolution and self-organization to generate rational structural shapes with a computer. This book describes the morphogenesis of the concept of flux structure through four projects - Island City Central Park and Kakamigahara Crematorium (with Ito) and Qatar Education City Convention Centre and Florence New Station (with Isozaki).
