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.
只有为自由而前赴后继人们，才让现在的人们享受和平年代，向英雄们致敬。
两个破防的泪点：一个是万里说“百里是我哥，你也是我哥，七连都是我哥。”一个是最后七连全员牺牲，只剩万里一个人报到：“第七穿插连应到157人，实到1人”。致敬先烈。
很好，比第一部还要饱满，主旋律影片几乎成为当代类型片的top了，我们是可以做出工业化好电影的
文戏少了许多，战斗画面更加激烈了，令人潸然泪下的点也很触动，明知道会这样发展的剧情，到那个点还是忍不住酸鼻子。这就是钢少气多的人民志愿军吧！
真理，只在大炮射程之内。
战争是残酷的，有些地方还可以！但是还是有两点我觉得没有改善，1人物2节奏感！人物上来说还是不够饱满，尤其是伍万里，我个人感觉他在第一部的冲动还可以说是初生牛犊不怕虎的话，那么第二部里的冲动表现就让我对这个人物没有一丝好感，还有就是对美军的刻画还是呆板不够立体！节奏感是现在国产电影急需改进的地方，这电影某些时刻让我觉得好多余，比如抱着五千里的尸体时美军突然的停手不接着烧啦，还有比如一群美军围住啦伍千里突然停手啦？坐看伍千里炸桥吗？实在觉得在故事上需要更多打磨，千万不要只是为了让人感动而强行煽情，水到渠成的自然才能使得故事更有回味，比如像拯救大兵瑞恩
打得我看懵了，几次分不清敌我，结尾有点多余，叫那一声但吴京别出现最好了我不过去拍一次没完成的任务，也算有意义
希望如果有下一部，导演编剧还是多抓抓剧情故事线吧
没有打不死的英雄
徐克的“独自上场”，令时长虽未减去多少却大幅提升观感的下集，成了最符合大档期需求的动作类型片，很多上集里被单纯渲染为狂轰滥炸的场面都被注入“有趣”的设计，无用但必需的文戏也成了头尾的装点，更为凸出战斗转场的层次感与刺激点的连续。
感觉这一部比上一部好，都三月底了，而是是周一很晚的晚上，电影院居然还有这么多人看。 我其实不喜欢看战争片，我喜欢看到人有尊严体面地活着，不喜欢看到人被枪炮炸得体无完肤。我痛恨一切战争。 但是中国人真的好了不起啊，那样的年代，那样的气温，感觉真的全凭一口气一股信念吊着了。
看完上部，我就说还可以再拍3个小时，这不就是了！但虽然是高潮部分，反而没有上部那么有层次了，文戏有故意喊solgan的嫌疑，讲悲壮，讲惨烈，讲中美当时的差距倒是很到位，战争的残酷和无奈也第一次有所触碰，不太喜欢这样这头没讲完就讲那头的节奏，眼花缭乱的剪辑有些无所适从，但或许这就是亲历者的感受，观众失去上帝视角反而彻底沉浸式体验了。
感觉不如第一部了，没哭出来，有点像以前玩过的射击游戏。能够想到从水管进入泵房真是厉害！
比第一部好，但是有些偏离历史了，水门桥战役之惨烈还是要看历史才能感知到，致敬先辈英雄们❤️
充分展现了志愿军不怕死的精神。但国力的差距实在是太大了，制空权、武器装备。牺牲那么大炸的桥，并没有成为障碍。
影片高潮不断，战斗不断，马不停蹄，几乎无修整就接连奔赴下一个战场，慢镜头和长镜头穿插得当，是电影很好的注释和表达。
全片一直在打，很压抑，看完以后心里堵得慌，费那么大劲，消耗那么多血肉战士，最终只是把桥炸出了一个小洞，人家飞机一来就能修好，这是一场根本没有胜利的战役，但是他好像一直在告诉我们，对于这场力量悬殊的仗，我们抱有必胜的信念。信念坚定，就胜利了大半。
相比于长津湖的刻意煽情，水门桥中第七穿插连应到一百五十七人，实到一人，是真真实实看哭了我。相比于长津湖的拖沓，这一部故事性更强，开篇即开战看起来也更紧张刺激。
希望如果有下一部，导演编剧还是多抓抓剧情故事线吧
两个字：燃，炸！
