Uma interessante analogia entre o crescimento e expansão das cidades e .... o ovo. Uma forma de representar de forma significativa a evolução das cidades ao longo de vários milénios, que se assemelha a um ovo cozido, ao ovo estrelado e ao ovo mexido.
"From its origins in the mists of time up until fairly recently, the
urban form resembled a hard-boiled egg. The city was a dense, compact
centre, protected by defensive walls from the evils of the wider world. (...) the rapid growth of population and industry around that
time, caused cities to expand rapidly. This is the poached-egg model:
the core retains its ancient function as the place of reference and the
seat of power, but it is surrounded by expanding rings of residential
and industrial areas, and infrastructural networks providing utilities
and transportation. But the centre cannot hold. Like a star at the end of its
life, the core of the city collapses under the weight of its own sprawl.
The car has made it much easier (and cheaper) to live, work and shop
near the ring roads than in the choked middle of town. This, the
scrambled-egg model, is also the most relevant type of urban development
today. And what type of egg will the city of the future resemble?
This will probably depend on the future cost of mobility, which might
become too prohibitive to sustain the present, scrambled-eggs model." (Stange Maps)
