The Science of Cities: Defining Size, Shape, Scale & Performance Using Percolation Theory
Показать описание
AURIN proudly presents a seminar by world-renowned British urban planner and geographer Mike Batty (Professor of Planning, University College London).
In this talk, Professor Mike Batty will explore how cities change qualitatively in terms of their performance as they change in size. Essentially cities like many animal species change qualitatively as they get bigger. Not only their shape changes but so does their performance across a range of indicators. We live in an era when big cities are being favoured much more than small and these ideas suggest that if you live in ever bigger cities you will reap ever bigger rewards. In fact this is an extremely controversial idea and it is weakened by increasing globalization and by the fact that big cities also seem to attract greater income inequalities. Our argument here turns on ‘how we define a city’ spatially which is an age-old problem. Professor Mike Batty will illustrate how we are addressing this problem using percolation theory where we explore how we fracture up a nation into regions and cities across many levels of hierarchy and in so doing produce thousands of city definitions, most of which refute the notion that big is better. We do this for UK cities. Others have shown the opposite from standard definitions of cities in other countries but our approach builds cities from the bottom up giving much greater flexibility in defining meaningful entities.
