closure feedback cycles
•Attractors
•Negative

insights
•Modelling systems is a complicated activity when treated with rigor. But conceptually, it’s fascinating.
•Second-order Cybernetics engages transdisciplinary approaches.
•Informatics is derived in part from Cybernetics.
inquiry & reflection
•What is the cybernetic approach for HCI Design?
•Does it make sense?
Thank you!
