There are only four types of cities

first_imgAny globetrotting tourist will tell you that all cities are unique. The challenge is to figure out what they have in common. Fortunately, there’s at least one thing that is nakedly apparent for every single city: the contours of its streets as seen from outer space. A team of researchers has now taken those street maps and analyzed them as mathematical networks. It turns out that all cities can be boiled down to just four different types based on the “fingerprint” of their street networks, the team reports online today in the Journal of the Royal Society Interface: a grid of medium-sized blocks that are mostly square or regular rectangles, a dominant fraction of small blocks with a diverse array of shapes, mostly medium-sized blocks with diverse shapes, or a mosaic of patches of mostly small squares or rectangles. For example, those who say that American and European cities tend to be “laid out differently” now have mathematical evidence. Boston’s famously confusing street map—which produces small and diversely shaped city blocks—is more like a European city’s than that of the typical gridlike U.S. city. And some of the largest cities are revealed to be a hodgepodge of different parts. The five boroughs of New York City (above) are closer matches to different cities around the world than they are to each other. Manhattan has the gridlike street layout of Brazilian cities like Campo Grande and Curitiba, while the Bronx’s streets look like those of Porto, Portugal. Brooklyn is strikingly similar to Detroit, Michigan, at least in layout. And Staten Island? It’s like walking the streets of As-Suwayda, Syria.last_img read more

Stefanos Tsitsipas beats Dominic Thiem in 3 sets to win ATP Finals title

first_imgLATEST STORIES Don’t miss out on the latest news and information. The Greek has already grown quite the fan base, partly because of a Bjorn Borg-style haircut and partly because of an aggressive playing style that is a bit old-school with frequent forays to the net.”He’s great for tennis, because he has a very attractive game style, one-handed backhand, comes in a lot,” Thiem said. ”It’s great that he’s up on the top. It’s great that he’s going to fight for the big titles in the future. I’m 100% sure of that. I’m also very sure of the fact that I can challenge him in every single match we’re going to play. … I really hope that we’re going to have a lot of big matches coming, the two of us.”Thiem beat both Federer and five-time winner Djokovic in the group stage but lost another big final after twice finishing runner-up to Nadal at the French Open.This one was much closer than his losses to Nadal, though, which made it tougher to swallow.”That’s why it’s probably mentally the most brutal sport existing, because you can play such a great match and end up losing in the championship match,” Thiem said. ”From that point of view, it’s a very disappointing loss, very hard to digest. But on the same hand, I had some amazing wins also.”It is the fourth year in a row that there is a first-time champion at the ATP Finals, following wins by Andy Murray in 2016, Gregor Dimitrov in 2017 and Alexander Zverev last year.Earlier, French duo Nicolas Mahut and Pierre-Hugues Herbert won the doubles title by beating Raven Klaasen of South Africa and Michael Venus of New Zealand 6-3, 6-4.Sports Related Videospowered by AdSparcRead Next Duterte officials’ paranoia is ‘singularly myopic’ Far from done What’s behind the display of Chinese flag in Boracay?

It was a great match from both of us.”The win caps a breakthrough season for Tsitsipas, who reached the semifinals of the Australian Open, won two ATP titles and became the first Greek man to break into the top 10.He also leaves London with $2.6 million in prize money for this win and joins a group of young players — including last year’s ATP Finals champion Alexander Zverev and U.S. Open runner-up Daniil Medvedev — who are seen as the top up-and-coming talents and challengers to the sport’s Big Three of Roger Federer, Novak Djokovic and Rafael Nadal.ADVERTISEMENT MOST READ Rice industry paralysis Matteo Guidicelli had saved up for Sarah G’s ring since 2014?
