From online The Ecology of Systems Thinking group to meeting in person, PJ came for a coffee, talking while watching me eat a full English breakfast. Worked through jams of orange marmalade vanilla, raspberry rose, blood orange marmalade, pear. Discussed history of science within the systems thinking community and the variety of notable figures, up to current day theoreticians and practitioners.
