DIGGING INVOLVES REMOVAL OF STUFF; DEFORMATION DOES NOT.

All of the above are extremely complicated ways of holemaking, involving removal of stuff and repeated cutting and gluing of the surface of the object that is being dug or drilled. A simpler process is continuous deformation of the object's surface, consequent (for instance) on the exercise of some pressure upon it (figure 10.1). This is a relatively smooth process, and one that does not involve any cut.
