In the blink of a geological eye, self-christened Homo Sapiens has existentially fouled the life support system of the spaceship it shares with a dwindling number of extra-species co-inhabitants. As the anthroposphere transgresses Planetary Boundaries that have protected the rise of modern civilisations, humanity is shockingly close to losing agency over its future. Can complex systems science provide understanding of the anthroposphere-ecosphere interactions that have brought us to this brink? More crucially, can it assist us in stepping back from the abyss? This seminar will provide no answers to those questions. Rather, with an emphasis on anthropogenic climate disruption, this novice with a Beginner's Mind will explore with the audience whether the human interactions responsible for this planetary crisis can be modelled meaningfully using complex systems science.

![Landscape and Flux Theory for Nonequilibrium Biological Systems
Jin Wang, Stoney Brook University
Life is characterized by a myriad of complex dynamic processes allowing organisms to grow, reproduce, and evolve. Physical approaches for describing systems out of thermodynamic equilibrium have been increasingly applied to living systems, which often exhibit phenomena not found in those traditionally studied in physics. Spectacular advances in experimentation during the last decade or two, for example, in microscopy, single-cell dynamics, in the reconstruction of subcellular and multicellular systems outside of living organisms, and in high throughput data acquisition, have yielded an unprecedented wealth of data on cell dynamics, genetic regulation, and organismal development. These data have motivated the development of concepts and tools to dissect the physical mechanisms underlying biological processes. Notably, landscape and flux theory has been proven useful in this endeavor [1,2]. Together with concepts and tools developed in other areas of nonequilibrium physics, significant progress has been made in unraveling the principles underlying cellular regulatory networks, differentiation and development, cancer, neural network dynamics, population dynamics, ecology, and evolution. Here, recent advances are reviewed with examples such as cell fate decision making with low and high throughput experimental data [3,4]. Many of these results are expected to be important as the field continues to build our understanding of life.
