剧情介绍

  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.

    整部电影的暗讽寓意不错:在科技面前可以用密码保护自己的住所却防不了陌生人的突如其来;科技大咖以为自己建立一个安全堡垒却轻易信任他人随意出入;700万的毕加索画在杀手眼里只不过是一张可以穿破的纸;在穷人眼里富人全都看不起他们;在离异夫妻之间最终剩下的都是戒备和利益。糟点就是设置最后杀死杀手的人不是很恰当和一部分镜头过于血腥……

    剧情无新意,结局有破绽:为什么杀了自己的后爹!左轮手枪居然有七发子弹!

    欲擒故纵真是高,把人迷得魂魄抛。用小电钻用镰刀,子弹一颗注了销。

    “结束战争”的唯一方法是自杀小队带着“神秘武器”滑冰到奥德,一行六人最后只剩下两人,途中发现是生化武器,为了阻止生化武器的研制、使用,女主带着样本自杀,全片以女儿贯穿了女主的信念。挺不错的。倾覆的救生艇周围,各种姿势冻死的人与冰面融为一体、年轻狙击手的口述,无不展现了战争的残忍

    当了妈的“安娜”战力也下降了,干不过女一,爷青结!

    Noomi 的动作片从未让我失望过。这部虚拟战争背景的影片,没有正面硬刚或者谍战的桥段。冰冷结冰的湖面上,士兵决心完成最关键的任务来结束战争。冻结的冰面变数多端,就好似暗喻了这场任务的不确定性。队员因为意外落水,组员间的互相不信任,发现任务的真实秘密后内心产生的动摇。到基地前的那段都很好看。最让人震撼的是无辜市民遭殃最后冻结在湖面的场景,令人心酸。最后到基地的15分钟剧情就有些狗血了。总体观感还是很不错的

    剧情老套,但有露点,最后是孩子拯救了全家,其实银行搞个人脸识别就没辙了,啥都拿不走。

    个别段落拍的是不错,但片子整体还是不够吸引人,显得很一般了

    在这场该死的战争中,获得自由的唯一途径,就是拒绝服从他们的命令。

  • 祁子议 6小时前 :

    2022032不知道为什么豆瓣打了这么低的评分,这是我近两个星期以来最DigIn的片子了。简直是末日战争公路片的冰雪版本,虽然人物刻画和剧本冲突不够完美,但依然不能掩盖它的亮点。当一切理想主义的光辉和使命摆在切身的亲情爱情利益面前,可能都不值一提,所以这才是人们想发明机器人的主要原因吧——没有情感和冲突去解决问题的最佳办法

    正在和老婆协议离婚的退休在山庄的年轻富豪,自以为遇到了真命天女,殊不知一步步陷入设置好的陷阱之中,几近失去所有的财富和性命之际,妻女的出现,使情况出现了更为复杂的变化。在千钧一发之际,竟然是五六岁的女儿开枪杀死女罪犯!有几个蠢点大牙的槽点,但不失为一部吸引人的惊悚片。

  • 莫如柏 6小时前 :

    剧情平淡无奇 女主够靓与角色形成的反差有点意思 老戏骨有限的表演时间现功力

  • 梦琛 8小时前 :

    各种元素 一盘散沙 再浅陋的主题也是必不可少的

  • 谛辰 8小时前 :

    反战题材,描写了一个有信念且强大的母亲。评分咋这么低,我不李姐。战争有时就是立场问题,没有对错。女主的前后反差,也是立场问题。一个不知孩子死活的妈妈,为了见到女儿,做多大的“错事”也说得过去。到终点之前,是带着见女儿的希望,明知携带的病毒是罪恶的,但也要坚持到底;希望幻灭之后,同样也是为了让不知死活的女儿远离病毒的威胁,那不惜一切销毁病毒也是合理的。男主后来活过来了,确实有点不合理,挨一枪躺冰上,早就应该冻死了吧,找也很难找到。女主都快死了,就这样撞上了大本营,确实有点巧。滑冰小分队还蛮新颖的。

  • 苍沈靖 9小时前 :

    6/10.

  • 真夏真 0小时前 :

    故事完整,女主颜值有说服力,为拉分强打五星。“你以为别人约你是因为你有趣,其实是因为你有钱”,富豪警示恒言。
