  What is complexity? property: Complex collective behavior: each typically following relatively simple rules with no central control or leader. It is the collective actions of vast numbers of components that give rise to the complex, hard-to-predict, and changing patterns of behavior Signaling and information processing: Adaptation: All these systems adapt—that is, change their behavior to improve their chances of survival or success—through learning or evolutionary processes an alternative definition of a complex system: a system that exhibits nontrivial emergent and self-organizing behaviors. How to measure complexity effective complexity Gell-Mann proposed that any given entity is composed of a combination of regularity and randomness. To calculate the effective complexity, first one figures out the best description of the regularities of the entity; the effective complexity is defined as the amount of information contained in that description, or equivalent...

  引子 最近这两年逛了70+ 湾区图书馆，覆盖了san mateo 和 San Leandro 以南到 san jose 所有图书馆，以及部分三番及以北的图书馆，每一个都拍了很多照片，做了笔记记录，以下是其中的值得一提的图书馆~~ 东湾 Fremont Main Library ⭐⭐⭐⭐⭐ 热闹游乐园一角的宁静而又不失乐趣的灵魂港湾 位于Lake Elizabeth 一角，湖的周围满是各种来烧烤或者野餐开party的人，还有各种游乐设施，比如水上乐园，pickleball场地，船坞等等，非常热闹 图书馆占地面积很大，所以整体非常宽敞。 里面有很多有意思的小装饰和布置， 比如窗边的小绿植，以及植物角 还有各种历史文化的小展柜， 二楼围着中间的“光柱” 放了一圈公用电脑，感觉大家围着这光柱用电脑的场景让人不禁往科幻片的方向遐想。 一楼还有二手书甩卖角，小说类50美分一本，非小说类1美刀一本，教科书2刀一本，选完书自己把钱投入旁边的信箱 还有一楼中间的仔细去，巨型的圆弧落地窗外是广阔的草地和蓝天白云，在这里自习一定很惬意 但是只有2-3人 study room，没有大型study room Hayward Public Library ⭐⭐⭐⭐⭐ 光影之间的摩登书屋 hayward public library 地处hayward downtown， hayward 给人的传统印象是湾区比较差的区 确实能看到很多破落的地方，比如流浪汉和奇怪的人很多，图书馆门口就有，养老院门口还有一个帐篷。这是暗的一面。 但让我吃惊的是光的一面。 首先是距离不远的养老院，竟然还配备了一个专属的日本花园 Japanese Gardens。 这个日本花园十分精美，虽然面积偏小，但是内容丰富而精致，有山，池，树，花，石，瀑布，鲤鱼，岛，桥，庭，石灯笼，悬崖，河，曲径，沙 而且都精心布置和修剪，十分雅致，在其中散步是一种享受。感觉精致程度不逊色于sf 的japanese tea garden，和 南湾的 hakone garden 而且一旁还有个小的影院，最近在放映日本经典电影。 然后是Hayward downtown，意外充满艺术气息，各种大型壁画，还有随处可见的utility box 上面的精美画作。还有各种漂亮的公园，大树，古典风...
