Since 2015, the Action Mechanics program has advanced a new approach to thermodynamics, first outlined in Action in Ecosystems: Biothermodynamics for Sustainability (Ivan R. Kennedy, 2001). Developed with insights from research at the Sydney University Nitrogen Fixation Centre (SUNFix), this program explores:
-
Biological nitrogen fixation
-
Risk management of agrochemicals
-
Ecosystem action dynamics
At its core, the program quantifies Gibbs field energy required for sustaining quantum action in material particles, applying the principle of least (or stationary) action. This pioneering approach is detailed in recent publications in Scientia and Research Features (2023 & 2024).
Our Ackle Abstracts series simplifies these concepts into practical tools:
-
Mechanics Lessons – Teaching and expanding core principles of action mechanics.
-
Climate Lessons – Applying novel methods to current climate science challenges.
We invite you to explore these groundbreaking papers and discover new scientific perspectives that could unlock future solutions for planetary sustainability.
