All cities can be exactly mapped onto to all other cities

London has no equivalent of Montmatre, as far as I can see.

I think we are stretching the definition of the word exctly here.

geeta said that every single bit of london seems to be brooklyn

Does London have a Bronx?

I'm fairly sure you cannot map NYC onto Canterbury, but I'd be impressed if anyone could give it a try.

Suzy actually did most of both cities here.

I think the currently equivalent of Brixton is like a combo of Harlem and Flatbush, with Irving Place (the venue) dropped right into the middle of it, for fun.

Knoxville's answer to Le Marais is about 40 feet of road near Cummberland avenue, behind the law school. Cafe tables, gay men, dog shit everywhere. It's eerie.

"Nikos Salingaros (NS): For the past few years, I have been applying the analytic thinking of a scientist to find basic laws for architecture and urbanism, following the lead of my friend, the brilliant architectural theorist Christopher Alexander. The results derived so far show that a building, or city, is subject to the same organizational laws as a biological organism and a complex computer program. The New Architecture depends upon scientific rules rather than stylistic dictates."

1. dead by day, packed by night bar/club districts with entire population seemingly consisting of twentysomethings and cloistered immigrants

2. packed by day, dead by night neighborhoods which support an incredibly high property value and crazy shopping, shoe and furniture boutiques every 15 feet type of thing, population strangely consisting of professionals and gasp students

also

3. McMansion suburban neighborhoods where everyone leaves the house at the same exact time, businesses would be better off holding hours from 5-10pm, basically people putting up with a hard commute because "I don't want my kids to have to go to school in the city."

and what are the pressures that create these phenomena/how do really explain Georgetown or the Lower East Side evolving into what they've become?

get a copy of grady clay's 'real places' IMMEDIATELY. it's exactly what you're talking about.

Brooklyn, with a population of nearly 2.5 million, such that were it separately incorporated it would be the fourth-largest city by population in the United States, is larger in population than South London. The population is 65% non-white, nearly 35% black, 20% hispanic or latino of any race and 7.5% asian. Nearly 38% of residents are foreign-born. There are large communities of Caribbean, Russian Jewish, Italian, and Arab immigrants, and the largest hasidic community in America.

Brooklyn has a land area of more than 70 square miles (more if you include water), which I imagine is smaller than that of South London. It includes multiple neighborhoods that are home to a mix of low-density residential housing, public housing projects, a regional downtown business district, and more than one waterfront industrial sector. Four bridges and one tunnel connect Brooklyn to Manhattan and Staten Island.

This, my friends, is why I'm moving.
