  • Distinguish parts which are significant from a design standpoint to fragments (broken glass example)
  • Atomic theory, example of IBM spelled out in Xenon atoms with AFM.
  • Examples of parts
    • Chemistry (functional groups) (reactions)
    • Mechanics (screws)
    • Electronics (resistors)
    • Architecture


Abstraction

  • decomposition of complex structures into simpler pieces
  • different ways to decompose depending on the goal
    • example: mechanical system (support structure) (power transfer)
  • Structural composition
  • Functional composition


Interfaces and standards

  • standard methods of connecting one part to another
    • screws
    • lego blocks
    • electrical wiring
    • plumbing


Hierarchical abstraction

  • Black boxes
  • interfaces between boxes


Decorative components


Connectors


Flexibility
