A transformation is an operation that changes the representation of a system without altering its physical content.
Transformations relate different representations of the same system.
Description
Transformations allow switching between different descriptions of a system, such as between different bases. They preserve the underlying physics while changing how it is expressed.
Properties
- changes representation
- preserves physical content
- linked to basis
