We will be working a lot with systems. We define them by setting a systemborder and look at everything thats in it and also at things that might go in or out through this border.
ToDo: Write a short summary about this tedX-talk.
Worlds are Systems in which we find ourselfs being, living, acting.
In my opinion we should be aware that different worlds exist, try to understand them and use this to get an idea on what to do.
