Query: Exhausting!

Calculus textbooks read easier than this book. The content is probably concise but the communication is not. The writing is awkward and often incoherent.Whatever happen to the simplistic yet skillful writing style of a Hemingway? His style was neither haughty nor indolent. He did not have to impress with fancy wordage. And his simplistic, flowing style took far more effort and thought than the rudimentary level of stringing out difficult sentences.This book is okay for the intellectual or the elitist but for the real world it can be painful. Architects are not always known for their communication skills. This book does'nt help.
