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.
但这类表达反抗的，种族歧视的，战争创伤的故事，却总是让我们不仅要反思，为什么我们会如此激动，为什么我们会感动或愤怒，时代明明在进步，可那些永无休止的问题为何却总是挥之不去，萦绕脑畔
自由的代价是什么？Everything ! 三名南非战士行动失败被困银行，在明知没有退路之后提出释放曼德拉作为交换人质的条件，通过人质的众生相可以感受到那个时候南非种族隔离的严重性，黑人地位的低下，三位战士的牺牲最终促成了释放曼德拉运动。
各种型号的今井翼都好帅，有魅力；如果阿诚不是骗婚gay（最低），人设还是蛮适合做伴侣的。
我不了解一个男同喜欢上女生的概率有多少 但从电影里看出的 安藤同学从压抑自己到拆下围在身边那堵墙到可以和周围的人融合 是个自我和解的治愈之路。
只要我们有一个人被拷着，就没人拥有自由。
即便这一切是个童话，可愿意去相信，并为之奋斗的你，才是真正的勇士
I don't know.
性少数群体也想做一个有幸福家庭的普通人，世界是有摩擦力的而不是理想状态的，大多数总是会对少数有着恶意不解和攻击，盼望每个人都在不断前进成长不再迷茫，男主演技有些不好。
自由的代价 牺牲。牺牲自己唤醒自由
What's the price of freedom? Everything!
前半部分的情节和节奏尚可，后面就一言难尽了。总体上不够打动人。
这片子评分有点低啊，个人赶脚挺不错的，黑与白，自由，人类，演员演技也不错
或许白左们今天来谈南非现状颇为讽刺，但是这部电影真正关注的并不是历史与政治本身，而是自由与平等的诠释！是的，自由可以用用一切来换取，包括生命。自由也绝非妥协与忍让得来，反抗与牺牲是自古以来换得自由与平等的第一步！
同为动作类型片，重看《无耻混蛋》，我恨不得一气看完。这个……
其实是一个既要又要的故事，这是人的天性当然无可厚非，但是它与爱的排他性对立，与普世的价值观对立。出路是什么，只能他们这个群体自己找了，我们再怎么样也不可能感同身受的，我们能做的就是包容不同。
总体来说质量还行，不过剧情进展太和平了，显得过于理想化了，其实在1980年，南非的种族歧视制度还是非常残酷的，但影片里太多白人是同情黑人甚至反对种族歧视制度的，这是在让我无法相信。关键历史上这次事件的真实情况被改动的实在太大，除了大框架，细节方面跟历史真相完全不一样。我给4星7分！
她喜欢看BL漫画到接受不了自己男友的BL
摩天轮上，女主羞涩地想要表白，但一直说不出口，男主主动说「我喜欢你」，女生喜极而泣。看到这段，在联系到现实中很多gay一面说自己是同性恋，一面又骗婚生子，目的达到后就冷暴力妻子……觉得男主惨，女主更惨。不过从某个角度来说，男主只是个高中生，他努力想要融合进刻板印象及其深的高中生活，做个普通学生。他最终也意识到自己的行为不对，不再伪装。
就是篇幅有点长....
自由的代价是“生命的一切”。故事很精彩，描绘了南非一群为了理想和正义而战斗、牺牲的战士和英雄，同时也展示了殖民主义、种族主义分子的偏狭残忍。
