Whoever said that engineering is boring? In Tianjin, China the Yongle Bridge over the Hai River was equipped with a Ferris wheel, consequently combining dull infrastructure with fairground fun! It’s height of 120 meters makes Tianjin Eye the fourth tallest Ferris wheel in the world.

260px-Ferris-wheelThe word Ferris wheel, by the way, is derived from the name of it’s inventor, George Ferris. He built the first one for the 1893 World’s Columbian Exposition in Chicago. The 80 meter tall construction was inspired on a bicycle wheel, in which the iron spokes maintain the tension in the wheel.

Sometimes the traveler strays from his straight path and finds himself in need of guidance. For this reason the guiderail (or guardrail, or crash barrier) was invented. Besides its guiding function, it also has a safety aspect; it protects people and goods along the side of the road against the impact of incoming traffic. The guiderail is so common that the average motorist barely notices its presence anymore. Until he comes in contact with it, of course. Or if he finds himself stuck in traffic next to one. For a long time, without any other distractions. Then he rediscovers it and certain questions start to arise in his mind.  Continue reading

Hear no evil, see no evil…

sound barier

This week, hundreds of prominent scientists, including Stephen Hawking, published an open letter warning against the use of autonomous weapons, such as military drones that can select and attack a target without human control. It is the well-known specter of the invention turning against its inventor, of technology ultimately taking over the human race. It is clear that this is no longer fiction. In numerous fields, technological and economic, humanity is being dominated by its own inventions. Also in spatial planning. Have we become enslaved to our ever growing need for more infrastructure?

Mankind can roughly be divided into two: city people and nature lovers. Granted that there exists a potential overlap between the two groups, most people still have a clear preference for either the city or the countryside. Nevertheless, it is rare for an urban area to be situated directly next to real nature. Continue reading

L: Hofplein, Rotterdam before WW II, R: Luchtsingel

Before May 14, 1940 Rotterdam was considered a compact city. The street profiles were generally narrow, even for that time. Ports located in the center of the city were becoming inaccessible for road transport. The smoke of the bombings had not cleared until the city government started making reconstruction plans. Plans in which space was created for wide roads cutting through the city center. After the war they were executed rapidly. The previously lacking access to the city wwas laid out and the spaces in between were filled in a more or less ad hoc manner, during the decades that followed. Rotterdam had become infrastructure instead of a city.  Continue reading
