July 11, 2017 – 2:30 am

This week’s episode has us discussing the use of abstraction in engineering and in pet management.

  • Why is it important? It allows you to deal with a problems in a more componentized way.
  • A good gauge for abstraction is when you create something, do you just “ask it questions” without fear that it will do something unexpected

Examples of abstraction:

  • Shadow Is  a Kitty, and she eats. Her favorite food is tuna
  • Unicron is a giant robot and he eats. His favorite food is earth.
  • Amoebas are single celled organisms and they eat. Their favorite food is brain tissue.

  • They all eat
  • They all have a favorite food
