Living in Information Space
Describing abstract destinations
Content versus Index Addressing
Information can be described according to what it is ("content addressing") or where it is ("location addressing") alternatively, you can describe the path to find it.
Easy to describe, difficult to find
There are destinations in abstract space that are easy to describe, but difficult to find.
In the physical world
Information structures physical space according to our destination.
In the information world
Pick a number.
Now find it.
Alternative information spaces
What if they were page numbers in a book?
How do you look for an entry in a dictionary?
Structure of abstract space
What is the structure of these information spaces?
This procedure, dividing the space into smaller halves, is known as binary search.
Algorithms are procedures for constructing and navigating abstract spaces. A typical example is a binary tree constructor algorithm.
Information in physical space
Physical space can be given abstract content through information design.
Physical space can also be navigated using abstract algorithms:
