既然还没人提，那可以看看克里斯托弗·亚历山大的《城市并非树形》[0]，了解一下建筑师对“自发演化”与“规划式”城市的独到见解。[0]：http://worrydream.com/refs/Alexander%20-%20A%20City%20Is%20N...
Since nobody has cited it yet, see Christopher's Alexander "A city is not a tree" [0] for an architect's take on "natural" vs. plannes cities. [0]: http://worrydream.com/refs/Alexander%20-%20A%20City%20Is%20N...
…页面反过来又可以链接回这些页面，形成极度复杂的环状结构。关于树状结构在城市规划中的局限性，一些有趣的讨论可以参考克里斯托弗·亚历山大的《城市并非树形》（他也是软件工程中 Design Patterns 运动的灵感来源）：http://www.rudi.net/node/317
…the page can link back to those pages in turn, producing cyclic structures of immense complexity. For some interesting discussion on the limits of tree structures with respect to urban planning see A City is Not a Tree by Christopher Alexander (who is also the inspiration for the Design Patterns movement in software engineering). http://www.rudi.net/node/317
…都可以被建模成一个系统。很遗憾，这正是目前 Tech/STEM 界占主导地位的思维方式。叫得最欢的人（通常是读过索卡尔的人）往往最搞不清什么时候该用什么框架。克里斯托弗·亚历山大的《城市并非树形》[1]就是个极佳的例证，展现了“科学至上”的思维定势是如何让我们与美好的事物失之交臂的。另一个关于蠢人的典型例子（这种例子可太多了）就是认为智能合约…
…can be modeled as a system. it's the mindset that dominates Tech/STEM sadly. those who scream the loudest (usually those who read Sokal) are also the most clueless about what framework to use when. "A city is not a tree"[1], by Christopher Alexander is a fantastic example of how a "science above everything" mindset keeps us from having good things. Another example of fools (we have many) would be the idea that smart-contracts,…
克里斯托弗·亚历山大的《城市并非树形》是另一篇关于系统思维（systems thinking）的绝佳论文。http://www.bp.ntu.edu.tw/wp-content/uploads/2011/12/06-Alexa...
Christopher Alexander's A City is Not a Tree is another great essay on systems thinking. http://www.bp.ntu.edu.tw/wp-content/uploads/2011/12/06-Alexa...
克里斯托弗·亚历山大的《城市并非树形》非常值得一读，推荐给还没看过的朋友：https://isites.harvard.edu/fs/docs/icb.topic1050153.files/A%...
Christopher Alexander's A City is Not a Tree is worth reading, for anyone who hasn't. https://isites.harvard.edu/fs/docs/icb.topic1050153.files/A%...
…因为付费墙打不开了）结尾给出的结论是“唯一的解决办法就是在大家最想去的地方多盖房子”，听着挺有道理，但其实并不对。就像克里斯托弗·亚历山大在《城市并非树形》里阐述的那样，“场域”（place）和“区位”（location）不是一码事。只要高效地将一个地方与其它区位连接起来，我们就能将它的场域辐射范围大幅外延。盖房子固然要盖，但真正靠谱的公共交通同样得建。去帮…
…can't load again due to paywall) ends on the note of "the only solution is to build more housing in the most desired places" which is well enough but not true. like Christopher Alexander explained in A City Is Not A Tree, places and locations are not the same thing. We can extend a place far beyond its location by connecting it efficiently to other locations. Build homes, yes. But build really good transit as well. Help…
