Comparative Mysticism
Strip away the theology and mystics across traditions report the same phenomenology: ego dissolves, boundaries vanish, dimensionality expands. That convergence demands an explanation.

Gene-Culture Coevolution
Most animals are shaped by their environment. Humans reshape their environment — and that feedback loop has been quietly rewriting our genome for thousands of years. Gene-culture coevolution is the theory of how.
Cliodynamics
Can mathematics predict when societies will destabilize? Cliodynamics — Peter Turchin's brainchild — applies structural-demographic theory to history and keeps making uncomfortably accurate forecasts.
Free Energy Principle (Redirect)
The Free Energy Principle is either the most important idea in neuroscience or the most over-extended. Either way, you need to understand it. This is the clearest starting point on the site.
Technosignatures
Forget radio signals. The modern search for alien civilizations looks for Dyson spheres, industrial chemistry, and assembly index anomalies. Here's what JWST can actually tell us—and what remains frustratingly out of reach.
Topological Data Analysis in Neuroscience
Traditional statistics asks "how much?" Topology asks "what shape?" Topological Data Analysis applies that question to neural activity — finding structures in brain data that dimensionality reduction destroys and that turn out to matter.
Assembly Theory
Lee Cronin's assembly index measures how many steps it takes to construct a molecule. Above a certain threshold, only life produces that complexity — making it a potential biosignature anywhere in the universe.
