Architecture: What does Big Data mean for our cities?

Size, population and the number of petrol stations can yield fascinating insights into how our cities function best - but we must remember that any self-organising system is more than the sum of its parts.

In a blog post last year, the scientist Stephen Wolfram, creator of the Mathematica software and the “computational knowledge engine” Wolfram|Alpha, suggested that the next revolution would be in “personal analytics”. He demonstrated this idea by collating and charting his life using his vast archive of personal data, including every email he had sent since 1989. In this way, he could see which years were the most busy or what times of the day he sent the most emails. His desktop calendar also revealed data about the course of an average day, while his phone records showed who he was talking to and for how long.

Wolfram’s company has already released a similar app on Facebook, so that people can chart their personal data to see everything from which friends live the highest above sea level to how networks of contacts interweave. We are, Wolfram might suggest, the sum of our information trail. Our lives have become data sets to be probed, charted and, once collated, analysed for efficiencies and savings.

In the new age of “Big Data”, does the same go for our cities? Just as Wolfram has reduced his life to packets of data, many urban thinkers now believe that the city is no longer just a place but a living field of information to be harvested.

Big claims are being made for this notion. Le Corbusier once called for the rationalisation of the city, making it a machine for living; today, many think that data, in the words of Assaf Biderman, the associate director of MIT’s Senseable City Lab, will make our cities “more human”.

Urban living used to be an art. Now, it is a science, burdened with the heavy-sounding label of “quantitative urbanism”. It is preached with the moral fervour of a Victorian public health official and involves some of the biggest names in the software, consultancy and infrastructure industries: IBM, Cisco, Philips, McKinsey & Company and Booz Allen Hamilton, among others.

Yet away from the hard sell, does this quantitative approach to ourselves and our cities tell us anything? Is the accumulation of data the same as the development of knowledge?

In 2003, the British-born physicist Geoffrey West started to study the metabolism of cities and soon came up with some surprising results. West wanted to find out whether the zoological rules first devised in the 1930s by Max Kleiber – which showed how all forms of life, from a fly to an elephant, follow the same equation that combines size, energy use and life expectancy – might apply to something as large and chaotic as a city.

West and his team at the Santa Fe Institute gathered together a huge data set: measurements of scale for urban centres in the US of over 50,000 citizens; statistics on “gross metropolitan product”; crime figures; the amount of money made by petrol stations in all 50 states; patents, as well as tax returns. Then, they put it all together into one database. They also included figures from the National Bureau of Statistics of China and Eurostat and even measurements of road surfaces from across Germany, as well as the amount of copper used in overhead wiring.

Surprisingly, the results reduced the life of a city to a mathematical rule: a Kleiberesque “unified theory of urban living”. So, while we can view individual cities as having their own particular history and personality, underlying rules apply that mean they have a lot in common with each other.

Yet cities do not follow Kleiber’s law exactly – rather than slowing down as they get bigger, cities speed up: they become more productive, creative, efficient and sustainable. As West points out, if you tell him the size and population of a city, he can cal - culate its crime rate, the number of patents it produces a year, how many petrol stations it needs, how many HIV-positive people reside there. According to West, the essential characteristics of a city can be reduced to an equation. Size matters, it seems.

Other urban thinkers, meanwhile, are starting to use the mathematics of complexity in an attempt to rethink how cities work. In this method, our understanding of networks and their emergent properties allow us to see how cities might work like beehives, ant or termite hills, the flow of liquids or the neural patterns of the brain.

This new urbanism – which views the city as a combination of networks and information – does not, in the words of John Keats, unweave the rainbow but forces us to question some of our long-held assumptions: what we consider to be the ideal size for a city; how we can use the qualities of complexity to rethink how the city is organised. Often, these discussions are conducted in the esoteric language of calculus and network theory. However, this can only have an impact when it is once again translated back into the language of the city – a place made up of people.

However, it would be wrong to think that data is the story. Information is the message, not the medium, and we need to be careful that this full-throttle embrace of data does not wash away the many other ways of looking at the city.

Just as Wolfram’s personal analytics do not show us the full extent of his life story, quantitative urbanism does not give us a complete picture of the modern city with all its elements. As complexity theory tells us, one of the characteristics of a self-organ - ising system – such as a city or a beehive – is that it will always be more than the sum of its parts.

Defining The Defenders: the long history of the superhero team-up

Netflix's new show draws on an established traditon of bringing together disparate characters.

Today Marvel’s The Defenders dropped worldwide. It’s the culmination of Marvel Studios’ interlinked series for Netflix, and all episodes will be available simultaneously as is the streaming services’ wont.

The Defenders, and the Netflix series that have preceded it, seem modelled on how the Marvel Cinematic Universe films have worked in multiplexes. At least superficially. Characters get their own solo films/series, which become increasingly interlinked over time, before all featuring together in an onscreen ‘team up’. Here, they combine against a threat greater than any they could plausibly win against on their own, sparring and generating alliances, friendships and even enmities in the process.

This structure, of course, is Marvel’s film and TV projects aping their source material. Marvel’s comics, and superhero comics more generally, have long relished the "team up" and the "super team". The use of this approach by Marvel’s other media ventures is intuitively right, allowing the mass audience for film and television to experience one of the specific pleasures of how superhero comics work in the characters’ new medium.

The concept of the super team goes back a long way. The Justice Society of America, from Marvel’s Distinguished Competition, is usually considered the first. They debuted in All-Star Comics #3 (1940) and the team consisted of the Flash (the Jay Garrick version, Flash TV fans), Green Lantern, Hawkman, and now lesser known characters like Hour-Man, the Sandman (not the Neil Gaiman one), the Atom, The Spectre and Doctor Fate. Within a few issues Wonder Woman would join: as secretary. Because it was the 1940s.

What’s interesting about this initial super team is that half of these characters were published by All-American Comics (who actually published All-Star) and half by DC Comics themselves, making this an inter-company crossover. (The companies would later merge). It also used to be claimed as the first example of characters created separately, and with no intention of them being connected, interacting. It isn’t. There are countless examples in the pulp fictions of the late nineteenth century, but the claim stood for so long because it felt right that the original super team should be the source of such meta-fictional innovation.

The Defenders were created much later in comics history and first appeared in 1971’s Marvel Feature #1. The team, though, had its origins in the "Titans Three" an informal grouping of heroes who appeared in a three part story serialised across Doctor Strange #183 (November 1969), Sub-Mariner #22 (February 1970), and The Incredible Hulk #126 (April 1970).

All three of those comics were written by Roy Thomas. Caught on the hop by the sudden cancellation of Doctor Strange (#183 was the final issue), he wrapped up ongoing plotlines from the cancelled comic in other series he scripted, bringing the now title-less Strange into those other series in the process. A couple more appearances of the group together followed, before the team was formally named in the aforementioned Marvel Feature #1.

Dr Strange. The Sub-Mariner. The Incredible Hulk. It’s quite likely that anyone reading this who is only familiar with the publicity for Netflix’s The Defenders would be surprised by that roster of headline characters. (And that’s assuming they’re even familiar with Namor the Sub-Mariner, a character of 1939 vintage who has not yet reached the MCU.) This is a radically different group to Daredevil, Jessica Jones (a character not even created until the 21st century), Luke Cage and Iron Fist, the stars of the current TV series. None of the telly team are characters a Marvel zombie would associate with The Defenders, although Iron Fist has been a very occasional member of the team’s roster, as has Luke Cage. (In which context, it’s unfortunate that Iron Fist has been the least liked of Netflix’s series, with a mere 17 per cent approval on Rotten Tomatoes.)

The complete absence of all three of the original Defenders from its television incarnation could be seen as an odd decision. Neither Benedict Cumberbatch’s Steven Strange nor Mark Ruffalo’s Bruce Banner are expected to turn up, even for cameos. Marvel Studios has policed a strict division between its Netflix series and its cinematic outings, despite announcing them as being set in the same "continuity". The fourth "classic" Defender is even less likely to turn up. The Silver Surfer (who joined the team in 1972, less than a year after it was formed) is, due to some bad deal making in the 90s, off limits to the MCU. His film rights sit with Fox, who utilised him in the rightly all but forgotten Fantastic Four: Rise of the Silver Surfer (2007). 

One of the reasonably consistent features of previous incarnations of The Defenders is that the characters have generally faced mystical threats. They first teamed up to fight monsters from HP Lovecraft’s Cthulhu Mythos, and generally their antagonists have operated on that kind of scale. With Stephen Strange in the gang, that makes sense. You don’t need the sorcerer supreme to take out organised crime. But organised crime is largely what you’d expect Daredevil, Luke Cage, Jessica Jones and Iron Fist to take on, especially based on the Netflix versions of the characters. All four are "street-level" heroes, operating in New York, interacting with characters like murderous vigilante The Punisher and Kingpin of Crime Wilson Fisk. Perhaps splitting the difference, their team up series will see them take on The Hand. This is a ninja organisation, with mystical origins, that is nevertheless involved in organised crime and can be presented, as it has been so far for Netflix, within the context of crime stories.

Marvel’s Chief Creative Officer Joe Quesada has defended The Defenders being The Defenders by pointing out that the original team are largely unknown outside comics fandom, and their name means nothing to the public at large. (Although they have, of course, heard of all three of its constituent members.) Of course, for some this might sensible provoke the question "Why use it then?" What is this series called The Defenders at all?

The (original) Defenders were seen as a "non-team", a phrase occasionally used in the pages of their appearances. There was something deconstructive about this kind of team up. It was the pairing of characters who were unsuited to working, even to appearing, together and who would really rather not. (They had, after all, been brought together in the first place simply because Roy Thomas happened to write their separate titles.) The stories told with the group in some ways challenged and confronted the cliches of the decades old form that had begun back in All-Star Comics #3.

The line-up, and tone, of Netflix’s Defenders more resembles that of another, deliberately slightly interrogative non-team, that of the short-lived Marvel Knights book of 2000-2001. This did share The Defenders somewhat abstract definition of "team", featuring characters who didn’t like each other and didn’t want to work together, albeit without any mystical element to how they were brought together. Marvel Knights was also, in theory, the flagship of the line of the same name, at the time edited by... Joe Quesada. Hmm.

In recent years, Marvel have frequently cheerfully remodelled their comics - the original medium for almost all their characters - in order to incorporate changes and innovations pioneered as part of their film and television projects. Remixing their characters and the way they are grouped together in response to the success of their screen empire. The Guardians of the Galaxy, for example, have become more prominent in the comics, while characters whose film rights lie with film companies other than Marvel’s own, such as the aforementioned Fantastic Four, have been pushed to the margins. Accordingly, this August sees the launch of a new The Defenders title, featuring the lineup of characters from the television series.

Some loyal comics readers see this a case of the tail wagging the dog. Others might like to take notice of the metaphor used by comics writer Grant Morrison in his 2011 book SuperGods: Our World In The Age Of The Superhero. There, Morrison argued that comic books, while the medium in which these characters were created, was essentially the discarded booster section of the rocket in which they had been fired into the public consciousness, reaching vastly greater audiences in the process. 

“That’s not The Defenders,” commented a friend of mine on seeing a publicity photograph for the series a few weeks ago. It is now, mate. It is now.
