Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as:
HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS
only to find a reference to another leaf: Please see
HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS
and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.
This, I think, is the brilliance of Notion, and what makes it one of the best examples of “fidelity to digital information” that I’ve come across. The structure of the app reflects the structure of the web itself: digital content is purposefully formatted, like semantic HTML elements, and exists in a hierarchical structure (directories on the web, nested pages in Notion), yet can be linked and referenced to create a complex network of information. And pages in Notion reveal the structure of the information: when nesting a page within a page, the child page always displays on the parent page. There’s no way to create a child page that doesn’t display on a parent page, no way to obscure the structure of the information. The semantic structure of Notion reflects the semantic structure of the web itself.
Truchet's approach was more topological than geometric, and the qualitative aspects of pattern take priority over the metric ones. His principles provide a kind of metaphor for the hierarchy of separation and connection in all things.
Don’t play it like the flute. Play it as if it was the wind whistling through the desert dunes.
No matter what you love to create, there is something to be learned from the way Hans Zimmer approached the Dune score. We are all striving to create work that is novel, innovative, memorable, and inspiring. To get there, however, we tend to focus on getting things right, on avoiding mistakes, on “being professional”. Yes, it is important to have the commitment, dedication, and attention to detail of a professional. But being right? That will only take you so far. What is much more important is to approach the problem in front of you with curiosity and an open mind. With an urge to explore what can be found beyond the ordinary, beyond the right way of doing things. If you want to create something that nobody has come up with yet, it is important that you try out all the crazy ideas others are afraid to try, that you build prototypes, improvise, and freely play with the materials and the technologies you have at hand.
