Dr Michael Batty - 'Fractal geometry and cellular automata in urban design'

Though the title may sound a tad scary the concept of the lecture was pretty simple.

Fractal Geometry is an irregularity that has order e.g coastlines and trees. Batty used the Kosch curve (aka snowflake curve) to demonstrate this
Kosch Curve
Fractal geometry occurs in nature because successful patterns are replicated. Batty hoped that by finding an efficient (successful) model of urban growth then we could replicate it.
