Wai H Tsang - FRACTAL BRAIN THEORY
Chasing Consciousness
The Ubiquitous Presence of Binary Trees
This chapter explores the concept of binary trees and their presence in various contexts, including nature, evolution, ontogenesis, and the cosmic tree. It discusses how binary tree structures are fundamental to our bodies and brains, playing a significant role in cognition and underlying scaffolding.
What does symmetry and self-similarity between life and intelligence mean for the nature of reality? How are neurones like genes?
Today we have the extraordinary Fractal Brain Theory to discuss. After episode #38 about the World as a Neural Network, with Russian physicist and computer scientist Vitaly Vanchurin, i’ve become more open to a unified theory of universe that reconciles quantum mechanics with general relativity, as Vanchurin’s equations seem to offer. So when I was recommended today’s guest’s Fractal Brain Theory by one of the wonderful listeners, I was curious if a little sceptical given all the psychedelic hype about fractal geometry. So a symmetrical theory of repeating self-similar, self-modifying behaviour in the universe is not so far from the vision of the universe as a thriving, adaptable neural network. And according to today’s guest the symmetry directly connects the often divorced worlds of neurones, brains and intelligence with the world of genes, evolution and life.
He is multi-disciplinary researcher, computer scientist, musician and author Wai H Tsang. A self-taught thinker in the world of neurology, evolutionary biology, consciousness and philosophy of mind, Tsang is in the unique position of combining these traditions into a single theory of brain, that promises to solve even the hard problem of consciousness. Trained in computer science at Imperial college, he wrote the first version of his Fractal Brain Theory in 2016, in his book of the same name, and it was picked up by quantum consciousness theorist Stuart Hameroff, who invited him to the Science of Consciousness Conference, alongside heavy weights in the field like David Chalmers, Roger Penrose, Sue Blackmore, Donald Hoffman - many who’ve been on this show already. This recognition catapulted his theory into the field, so it’s with great pleasure that I include it on the show for us to compare alongside the theories of many of the giants.
