故事综述
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.

生动直白有趣的科普，香农熵和分组交换部分尤其好评，布里斯托这个可编程城市的概念有点酷哦，同系列的the joy of statistics也值得一看。冷知识：点击维基百科任何一页的第一个链接最后总能把你带到哲学philosophy的页面。
记住的：1、从维基百科推演，任何一个词语最终都回归到“哲学”上 2、二进制编码是香农在解决电话噪音时发明的 3、数学与现实世界的平行宇宙由数据链接 4、了解了香弄信息，出现频率越少的词汇携带的信息量越大 其他虚的没在记住了。 拍摄方式随性特别、被采访者的人物介绍安排巧妙
无需恐惧技术本身，应在意应用技术的目的。
数据（数学公式 ）=定性+定量；数据-信息-知识-智慧； 前十五分钟比较好，后面很水而且是广告
数据分析让人类更加精确的认识身边的世界，并加速了生产力水平的进步，与此同时还带来了新的问题:谁有权利收集数据并分析数据？谁又能决定收集的对象？谁又能够保证数据不被滥用或误用？这几个问题将持续困扰着生活在数字化时代下的当代人。矛盾伴随着事物发展的始终，这一点老马诚不欺我。
