Just over an hour on how one mathematical idea, self-similarity across scales, runs through biology, physics and cosmology: from the Koch snowflake and the bifurcation diagram to Kleiber's law and the fractal structure of space.
Why it matters for Neural Cosmology: the programme starts from the claim that reality is organised by one repeating computational architecture at different levels, from cellular bioelectricity to the cosmic web. The lecture is a popular introduction to the same intuition through the classic material on fractals.
