Research in Physical Review Letters introduces a temperature-like variable that addresses the breakdown of the second law of thermodynamics.

The Einstein relation links the strength of thermal fluctuations to energy dissipation, but it falters in non-equilibrium systems like chemical reactions or bacterial swarms. The newly defined variable is independent of — and thus could resolve — the limits of the Einstein relation.

Conventional approaches to modeling unstable or disturbed complex systems often take either a bottom-up or top-down approach. But these unidirectional models can’t capture the interactions between the small-scale behaviors and the system-level properties.

In a new paper in PNAS, External Professor John Harte
UC Berkeley and colleagues present a theory that could resolve this problem and offer deeper insights into systems from disturbed ecosystems to volatile economies.

How do we assess intelligence?

🎙️ Episode 5 of the 'Nature of Intelligence' season is out on podcast!

When it comes to assessing intelligence, people have all kinds of tests — the SAT, IQ tests, and so on. There’s controversy over how fairly these tests really measure human intelligence, but at the very least, we know that they correlate with some general reasoning skills when people take them. That assumption breaks down when we try to assess intelligence in non-humans. What does it mean when a large language model passes an intelligence test meant for humans? Does it actually have the same reasoning skills that a human does, or is it doing something else? In today’s episode, with guests Erica Cartmill and Ellie Pavlick, we investigate the best ways to assess intelligence in non-humans, whether animals or machines.

SFI President David Krakauer writes the introduction to the latest issue from ISOLARII — a palm-sized version of Philip K. Dick’s How To Build A Universe That Doesn’t Fall Apart Two Days Later.

“Themes related to the nature of reality are of profound interest to complexity science since they touch on questions of patterning, order, intelligence, robustness, and control,” says Krakauer. “PKD raises several of these and we are now in a position to start to address them. My own objective was to present some of these responses in a lyrical and experimental style.”

PKD's essay is “a mind-bending lecture on the fragile nature of reality and the quest for authentic human experience in an increasingly mediated world.”

Before writing their groundbreaking 1993 paper on Balinese water temples as a complex adaptive system, “Emergent Properties of Balinese Water Temple Networks: Coadaptation on a Rugged Fitness Landscape,” J. Stephen Lansing and James N. Kremer met by happenstance while surfing at the same California beach. Here they are pictured during a research trip to Bali, circa 1987. The 1993 paper will be featured in the upcoming fourth volume of Foundational Papers in Complexity Science, available soon from SFI Press.

Highly quantitative approaches to studying human interactions can miss important qualitative aspects. SFI Complexity Postdoctoral Fellow Izabel Aguiar, who holds a Ph.D. in computational and mathematical engineering from Stanford University, is developing models that synthesize a rigorous balance of quantitative and qualitative approaches to studying human relationships and other complex systems.
Welcome Izabel!

1973 – Herbert A. Simon published “The Organization of Complex Systems in Hierarchy Theory,” a far-reaching and reasonably accessible account arguing that complex systems can decompose neatly into digestible components.

SFI’s External Professor John Kaag makes the case for Simon’s paper prefiguring and facilitating our developing understanding of subjects from machine learning to climate change.

Read Kaag’s introduction, and Simon’s paper, in Foundational Papers in Complexity Science, Vol. 3 – available September 17 from SFI Press: sfipress.org/books/foundational-papers-in-complexity-science

🎙️ Episode 2 of the 'Nature of Intelligence' season is out on podcast!

What’s the relationship between language and thought?

Complex language is unique to the human species. It’s part of how we evolved, the backbone of our societies, and one of the primary ways we judge others’ intellect. Is it our intelligence that leads to our language abilities, or conversely, does our ability for language enhance our intelligence, or both? How do language and thinking interact? And can one exist without the other?

Join our guests Evelina Fedorenko, Steve Piantadosi, and Gary Lupyan to explore this important and often contentious debate.
