Around that same time, to better understand the discord surrounding the 9/11 attacks, Joshua entered the World Trade Center Memorial Competition. This project initiated research into the use of interactive architecture to both explore and ameliorate the traumas surrounding human dynamics. This led to independent research of creative, learning and adaptive behavior in sentient creatures and the societies they populate. This research led to work with Prof. Terrance Deacon at UC Berkeley, and others, on thermodynamically grounded theories of semiotics and abiogenesis — how living dynamics and semiosis emerge from non-living dynamics and sustain themselves.
At the social scale, Joshua was able to implement many of these research ideas in practice at the Exploratorium where he co-developed the Studio for Public Spaces (SPS) with Shawn Lani and others. SPS built a collaborative process and body of work that deeply explored these questions of vitality at the individual, community and institutional scales.
Sentient Societies is the next evolution of this praxis.
