For Bernard Tschumi, "drawing is thinking" and "being with a piece<br><br>of paper and a pen does not feel like working. It can be sheer bliss",<br><br>he writes, "seeing thought materialise itself in front of your eyes<br><br>through the almost unconscious mediation of your hand. It is a form<br><br>of notation of the mind."<br><br>This collection of previously unpublished drawings, diagrams, and<br><br>other remnants of the architectural process provides new insight into<br><br>well-known projects like the Parc de la villette and the New Acropolis<br><br>Museum, as well as tracing a number of unbuilt pr oposals and<br><br>speculations. Notations (Diagrams & Sequences) offers a unique view<br><br>into the working process of Bernard Tschumi and his office.
