Chapter 17
Observer Dependence

Scale determines the level of detail used to describe a system.
Different scales reveal different patterns while hiding others.

Understanding scale allows complex systems to be analysed without losing structural meaning.

Resolution defines how finely a system is observed or measured.
Higher resolution reveals detail, while lower resolution highlights broader patterns.

This chapter explores how description changes as observational resolution shifts.

Complex systems often contain more detail than can be directly described.
Compression reduces information while preserving the patterns that matter most.

This chapter explores how useful descriptions arise through structured information reduction.
