"A Theory of Architecture" is a book by NikosSalingaros published in 2006 by Umbau-Verlag. http://www.umbau-verlag.com/Buecher/ATOA.html The book explains, advances and promotes PatternLanguage thinking in architecture. The author introduces three laws of structural order. They explain what makes things most differentiable at different scales: * In the discrete scale, simple alternation makes things most differentiable, as in a light wave. * In the global scale, reducing entropy - which is to say, maximizing deliberateness - makes things most differentiable. * In the intermediate scales, a linked hierarchy of scales approaching but not exceeding e=2.718... makes things most differentiable. Good architecture, good systems allow for maximum differentiability. MinciuSodas is promoting this book. Please contact the publisher UmbauVerlag for free books for reviewers. --AndriusKulikauskas
