A witty, exhilarating and mind-expanding exploration of the word of our times - data - with mathematician Dr Hannah Fry. Following in the footsteps of BBC Four's previous gleefully nerdy, award-winning maths films The Joy of Stats, Tails you Win - The Science of Chance and The Joy of Logic, this new high-tech romp reveals exactly what data is and how it is captured, stored, shared and made sense of. Fry also tells the story of the engineers of the data age, people most of us have never heard of despite the fact they brought about a technological and philosophical revolution.
For Hannah Fry, the joy of data is all about spotting patterns. She's Lecturer in the Mathematics of Cities at UCL as well as being the presenter of the BBC series Trainspotting Live and City in the Sky, and she sees data as the essential bridge between two universes - the tangible, noisy, messy world that we see and experience, and the clean, ordered, elegant world of maths, where everything can be captured beautifully with equations.
Along the way the film reveals the connection between Scrabble scores and online movie streaming, explains why a herd of Wiltshire dairy cows are wearing pedometers, and uncovers the remarkable network map of Wikipedia. What's the mystery link between 'marmalade' and 'One Direction'?
The Joy of Data also hails the giant contribution of Claude Shannon, the American mathematician and electrical engineer who, in an attempt to solve the problem of noisy telephone lines, devised a way to digitise all information. It was Shannon, father of the 'bit', who singlehandedly launched the 'information age'. Meanwhile, the green lawns of Britain's National Physical Laboratory host a race between its young apprentices in order to demonstrate how and why data moves quickly and successfully around modern data networks. It's all thanks to the brilliant technique first invented there in the 1960s by Welshman Donald Davies - packet switching - without which there would be no internet as we know it.
But what of the future, big data and artificial intelligence? Should we be worried by the pace of change, and what our own data could and should be used for? Ultimately, Fry concludes, data has empowered all of us. We must have machines at our side if we're to find patterns in the modern-day data deluge. But, Fry believes, regardless of AI and machine learning, it will always take us to find the meaning in them.
将近三个小时全是战争场面，让人视觉疲劳，没有第一部火车上看长城那种美得动人心魄的神来之笔，本质上就是在看徐克的武侠片，最后结尾两兄弟的对话是最感动的地方，结果被突兀又难听的片尾曲吓了一跳，这歌太减分了。
不论镜头语言还是表演，不论是当时的电影环境还是现在都是经典！
潜伏的基础版，致敬为新中国解放所有贡献生命的烈士
后世对经典的致敬多种多样，有《潜伏》、也有《永不磨灭的番号》
2021.04.14@崔永元口述历史中心 剪辑叙事都非常流畅，故事略微流水账情节冲突不是很强，也许地下工作正是这样平淡如水，但又那般隐秘而伟大吧，向革命先烈致敬！｜｜2021.11.14 黑白转彩色修复版重温。
党的眼睛，党的耳朵。中国电影资料馆，4K修复上色版，清晰度很好，但是这个上色差强人意吧。
节奏很慢很慢，快一个小时了还在慢条斯理的进行家庭故事，可能真的是时代不同了，感受 不同了。
从电影里看，他们在上海的工作作用重要吗？
电影的故事原型为在上海从事地下工作的中国共产党党员李白。
修复的挺好，相似蒙太奇像刚学会拼命用，相对窃听可观看性没这么高，但58年拍成这样不错了，反派也有血有肉，就是女主有点样板了
令人动容的真实英雄事迹改编，令人动容的一句“同志们，永别了，我很想念你们”。单纯的电影技术有着不少缺陷，但是这样一个历史影像的余温，依旧能够温暖这片大地上的人们。3.5
向故事原型李白邱裘慧珍夫妇致敬！
王心刚演反派实在是……有点像乔宏演的爱情片
七连全军就义只剩一面旗，万里能留下来全因为是大年初一。
还是很有趣的，十七年中很具有代表性的谍战片，王苹导演的拍摄手法非常细腻，刚柔并济，让人感觉到李侠不仅仅是一个伟光正的英雄人物（虽然不可避免地用了很多仰拍镜头来突出他的伟大），更能看到他在日常生活中的细致敏感，体贴入微，对于家人和革命战友真挚和深沉的情感。情节起伏较大，在谍战剧大火的今天，依旧可以调动观众的注意力（虽然到后边叙事确实有些疲软）但是在那个年代能够如此深层次地讲好这个故事，将人物内心之中的伟大情怀很有层次地展现已经很不错了。感觉后边叙事有些过紧了，1949年前拍的时间好长，之后十几分钟结束让人有些猝不及防，不太明白如此优秀的谍报人员怎么就这么容易牺牲了。叠印的镜头语言效果很好，结尾处用电报哒哒的声音和交叉蒙太奇结合很棒，情绪点达到了，有被感动
红色经典啊，不过在电影中孙道临好不容易打入了敌人的内部，对于敌人给的消息我们一五一十报道出来，这样很容易让敌人警觉，让孙道临暴露啊。。。
孙道临浓眉大眼高鼻梁还方下巴……有几个镜头想到了留小胡子的谢霆锋。边上都是年纪大点的观众，会直接叫演员名字“王心刚要出来了”，和我爷爷奶奶一个样。
跑老远找到一家艺术院线看，彩色修复观感极佳。《潜伏》等谍战经典都能看到这部的影子，鼻祖。“同志们，永别了。我想念你们。”
最后一分钟“营救”电台版，除了节奏现在感受太慢，情感烘托还是很浓的。
推荐星级：★★
