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.
李白烈士，您所期盼的黎明，到了。
修复版能不能多排片啊，想看(⊙o⊙) 孙道临老师是真帅啊( ⊙ o ⊙ )啊！
一辆破车都能开上山顶，美军的装备却只能过那个破桥。
当黑白画面变得高清而又彩色时，我才知道，李侠离开监狱的那天，兰芬穿得是多么的好看。
被捕前孙道临发报的特写，成为地下党员的经典写照。
文革前的老电影还是不错的，孙道临真是演技派，王心刚很少见的扮了个反派
时代局限性太强。若不是修复上院线，几乎看不下去。“首部黑白转彩色4k修复故事片”这个意义超越了电影本身。
正好和《兰心大剧院》一前一后上映，都看了。两部谍战片，一部当代拍的彩色转黑白，一部当时拍的黑白修复成彩色。一部风格化小景别摇摇晃晃，一部程式化有板有眼端端正正。可前一部我觉得矫揉，后一部我却觉得真实，我被打动了。
其实它并没有达到我平时打五星的标准，但是为着这我已经很久没有见到的真诚，我想打五星。
那个时代的电影 导向很明显 摄制技术也相对偏弱。但演员的演技和表达能力真的太强大，彩色修复也非常棒，让眼泪的质感更绝了。我们永远不能忘记革命先辈们。
电影没有高超多彩的镜头语言，绝大部分转场也基本都靠叠化和黑幕，但恰恰是朴素真实的笔触，才能描摹出那个时代最坚定的信仰、最深沉的爱，正如敌人的形容“这般点划清楚，犹如一汪清水。”
总之，我更加喜欢这一部一丢丢。
1.比最新的（2021年）类似情节的电影拍得好，因为人家这个是真情实感，而2021年翻拍的这个是个垃圾，没有无产者奉献的真情实感
2.姚苇对李侠有微妙的情感，基本可解释全片最大的bug
影片拍摄的时候，还没有“谍战片”的概念与类型。但所谓“地下工作者”和“地下斗争”的故事情节，其实就是当今谍战的内容。孙道临与袁霞，完美地塑造了一对谍战情侣与特殊情境下的夫妻形象，既具有时代的典型性，又充满人情人性。人物形象的充实丰满，从而造就了影片能够具有相当的开创性价值。也成就了一部“红色经典”、“谍战经典”与“艺术经典”……
推荐星级：★★
致敬中国人民解放军，为了祖国甚至牺牲生命，什么样的大爱啊，有信仰的生命最有价值。
彩色修复的真不错(*๓´╰╯`๓)♡ 向老一代共产党人致敬
3.整体还可以，属于中等水平，但是又有一两个闪光点的电影
尽管那个年代宣传用途的电影说教意味从来都比较重并没有什么意料之外的东西，但这个4K修复加上色的质量还是值得去电影院感受一下。
