Cities scale like organisms—but the 15% salary bump isn’t a law, it’s a rough correlation with no mechanism, margin of error, or boundary conditions.

All briefs
Per Bak
Self-organized criticality is not a law of nature—it’s a sandbox with one working toy.
Benoit Mandelbrot
Fractals do not explain nature — they rename its roughness with precision.
Catastrophe theory
René Thom classified every possible way a stable system can suddenly break into seven geometric templates. The mathematics is settled; its 1970s use to explain animal and human behaviour was not, and a public critique said so.
Mitchell Feigenbaum
Chaos isn’t random — it’s tuned to a single number, discovered on a pocket calculator.
Stuart Kauffman
Biological order isn’t just selected — it’s attracted.
Mandelbrot set
Benoit Mandelbrot
Mandelbrot visualised a known mathematical object with unprecedented clarity — making topology legible through computation.
Riemann hypothesis
Bernhard Riemann
Riemann’s 1859 hypothesis is a precise, unproven claim about zeta zeros — central to prime distribution, yet untouched by proof for 165 years.
