Document Summary
Jean piaget (1896 - 1980): stages of development. A grasp of conservation of matter, of causality and an ability for classification of concrete objects. Only 30% - 35% of adolescents conquer fourth stage. A means of achieving stepwise refinement by accentuating relevant details (and, by. Examples from common experiences implication, suppressing unnecessary details) Sometimes, an abstraction removes the complexity of an underlying machine . At times, the abstraction might even be a safety measure. A shower knob not allowing you to scold yourself. A view of a problem that extracts the essential information relevant to a particular purpose and ignores the remainder of the information. The essence of abstraction is the extract essential properties while omitting inessential details. Abstraction is doing just what our small minds need: making it possible for us to think about important properties of our program - its behavior - without having to think about the entirety of the machinations.
